SQS Adapter

Properties   Config Settings  

The SQS Component provides access to Amazon's Simple Queue Service (SQS).

Remarks

The SQS Adapter connects to Amazon's SQS service to download or upload messages in queues. SQS allows you to create globally accessible queues on Amazon's servers. These queues can be used by developers to transfer data between distributed application components, without losing messages or requiring each component to always be available. Please refer to Amazon SQS documentation for details.

To begin set AccessKey and SecretKey to the corresponding values for the AWS account. Queue specifies the existing queue to work with.

SQS Receive Adapter

The SQS Receive Adapter will download messages from the specified Queue. To delete messages after they are downloaded set DeleteMode to OnSuccess.

By default if messages are not deleted they may be returned in subsequent polling intervals if they are still present in the queue. To prevent duplicate messages from being downloaded even if they are still present in the SQS queue set DownloadCacheFile to a file on disk where information about downloaded message is stored. When DownloadCacheFile is specified the adapter will check if the message has previously been downloaded, and will skip it if so.

SQS Send Adapter

The SQS Send Adapter uploads messages to the specified Queue. The SQS Send Adapter is designed to be simple to use and requires only minimal configuration. By default the adapter will read the SQS message data from the BizTalk message body, however Message may also be set explicitly.

Please refer to the section on adapter configuration for a description of how to configure receive locations and send ports for this adapter.

SQS Transmitter

Setting the SQS Adapter Configuration Properties for a Dynamic Send Port

A dynamic send port does not provide any transport configuration options in BizTalk Explorer because it is expected that these properties will be provided with the context properties associated with the message. These properties can be set in a custom pipeline or in an orchestration. To set message configuration properties in an orchestration you can do the following:

  • Add a Construct Message shape to your orchestration.
  • Configure the Construct Message shape to construct a new message. (for example Message_2)
  • Add a Message Assignment shape to the Construct Message shape.
  • Add code to the Message Assignment shape to initialize the message that you constructed and to set the appropriate configuration properties for the message.

Configuring the SQS Send Port with the BizTalk Server Administration Console

To configure the send port by using the BizTalk Server Administration console, use the following procedure:

To configure variables for a SQS send port:

DeleteMode Property (SQS Adapter)

Controls if and when the remote message is deleted after download.

Data Type

Enumeration

Possible Values

Never (0)
On Success (1)
On Failure (2)
Always (3)


Default Value

0

Remarks

This property informs the adapter as to whether or not it should delete a remote files from the server after a successful download. The possible values and their meanings are as follows:

NeverThe remote file is never deleted.
OnSuccessThe remote file is deleted after a successful download.
OnFailureThe remote file is deleted if the transfer fails.

Note: the default value is Never for data protection purposes. Unless modified this will result in the adapter continuously receiving the same data.

This property is not available in the Sender.

DownloadCacheFile Property (SQS Adapter)

The file location where downloaded message information is cached.

Data Type

String

Default Value

""

Remarks

This property specifies an optional file on disk which holds information about previously downloaded messages.

By default if messages are not deleted they may be returned in subsequent polling intervals if they are still present in the queue. To prevent duplicate messages from being downloaded even if they are still present in the SQS queue set DownloadCacheFile to a file on disk where information about downloaded message is stored. When DownloadCacheFile is specified the adapter will check if the message has previously been downloaded, and will skip it if so.

The DownloadCacheFileDuration configuration setting may be used to expire old entries from the cache file.

If this property is not set, no caching will be performed.

This property is not available in the Sender.

ErrorThreshold Property (SQS Adapter)

The maximum number of errors before the component shuts down.

Data Type

Integer

Default Value

5

Remarks

This property limits the number of errors that the adapter can incur before it shuts down and stops processing messages.

If set to 0 the adapter will never shutdown.

Note that if the operation completes successfully the current error count will be reset.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Sender.

Firewall Property (SQS Adapter)

A set of properties related to firewall access.

Data Type

Firewall

Remarks

This is a Firewall type property which contains fields describing the firewall through which the adapter will attempt to connect.

HTTPProxy Property (SQS Adapter)

A set of properties related to proxy access.

Data Type

Proxy

Remarks

This is a Proxy type property which contains fields describing the proxy through which the adapter will attempt to connect.

MaxBatchSize Property (SQS Adapter)

The maximum size, in MB, of the current batch (0 indicates no limit).

Data Type

Integer

Default Value

0

Remarks

This property limits the maximum amount of data the adapter can store before finalizing and processing the current batch to the number of bytes indicated.

Note: the default value, "0" indicates that there is no limit on the size of the batch. This value is not recommended for production environments as it may result in extremely large batches being held in memory before the adapter moves the data to the next stage of processing.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Sender.

MaxFileCount Property (SQS Adapter)

The maximum number of files in the current batch (0 indicates no limit).

Data Type

Integer

Default Value

10

Remarks

This property places a limit on the number of files that can be transmitted in a single batch.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Sender.

MaxFileSize Property (SQS Adapter)

The maximum size, in MB, of a file in the current batch (0 indicates no limit).

Data Type

Integer

Default Value

0

Remarks

This property limits the maximum size of any file in the current transmission batch to the number of bytes indicated.

Note: the default value, "0" indicates that there is no limit on the size of the batch. This value is not recommended for production environments as it may result in extremely large batches being held in memory before the adapter moves the data to the next stage of processing.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Sender.

MaxMessages Property (SQS Adapter)

The maximum number of messages retrieved from the queue.

Data Type

Integer

Default Value

1

Remarks

This property specifies the maximum number of returned messages.

Allowed values are between 1 and 10. All other values are considered illegal by Amazon.

This property is not available in the Sender.

MaxPersistentConnections Property (SQS Adapter)

The maximum number of simultaneous persistent connections when sending.

Data Type

Integer

Default Value

1

Remarks

This setting specifies the maximum number of simultaneous persistent connections when sending.

The default value is 1, which limits the adapter to using one persistent connection for the adapter at any one time. This means when ConnectionLifetime is set to Persisted the send adapter will first check to see if an existing connection is present before transmitting data. In the case where a connection exists but another instance of the send port is using the connection the adapter will wait for the connection to become free. A value of 1 effectively serializes all communication for the send port through one persistent connection.

By setting a value greater than 1 a pool of persistent connections can be created. This allows multiple simultaneous persistent connections to be used. When the send adapter is active it will check to see if there are any existing connections. In the case where a connection exists but is being used by another instance of the send port it will attempt to create a new persistent connection. If creating a new persistent connection would exceed the limit specified in this setting the adapter will instead wait for a connection to become free. Setting this to a value greater than 1 allows multiple simultaneous connections to be made while still taking advantage of persistent connections to reduce the overhead of re-connecting.

Note: This only applies to the send adapter.

The default value is 1.

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Receiver.

MaxThreads Property (SQS Adapter)

The maximum number of threads that the component may consume.

Data Type

Integer

Default Value

20

Remarks

This property limits the number of concurrent threads that the adapter may consume while completing its work.

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

MaxTransmissionBatchSize Property (SQS Adapter)

The maximum number of messages that can be sent in a single batch.

Data Type

Integer

Default Value

1

Remarks

This property controls the maximum size of an outbound message batch.

Note: be careful when modifying this property as it directly effects the efficiency of the transmit adapter. Setting MaxTransmissionBatchSize to a low value in an environment that requires transmission of large quantities of data will result in the adapter accumulating several small batches. If TransmitBatchMode is set to Parallel, this will result in the adapter transmitting many small batches at once and can put a heavy load on the processor.

Conversely, if TransmitBatchMode is set to Serial, setting MaxTransmissionBatchSize to a large value may result in long transmission delays as the adapter will wait on existing work to complete before accepting new messages from the BizTalk Message Engine. This is especially true when the adapter is transmitting large data.

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Receiver.

Message Property (SQS Adapter)

The message to add to the specified queue.

Data Type

String

Default Value

""

Remarks

This property specifies the message to add to the Queue selected by Queue. If left unspecified the BizTalk message body will be used as the SQS message content.

This property is not available in the Receiver.

MessageGroupId Property (SQS Adapter)

The ID that groups together messages in a FIFO queue.

Data Type

String

Default Value

""

Remarks

When uploading messages to a FIFO queue, only messages that share a MessageGroupId are guaranteed to be processed in-order. If all messages should be processed in-order, then this should be set to an arbitrary static integer.

This property is required when UseFIFOQueue is True and not applicable when UseFIFOQueue is False.

This property is not available in the Receiver.

Other Property (SQS Adapter)

Defines a set of configuration settings to be used by the component.

Data Type

String

Default Value

""

Remarks

The adapter accepts one or more configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the adapter, access to these internal properties is provided through the Other property.

The Other property may be set to one or more configuration settings (name/value pairs). Set one setting per line. For example: configname1=value1 configname2=value2

PollingInterval Property (SQS Adapter)

The amount of time, in seconds, between download attempts.

Data Type

Integer

Default Value

60

Remarks

The adapter will wait for the number of seconds indicated before attempting another download.

This property is not available in the Sender.

Queue Property (SQS Adapter)

The name of the queue to access.

Data Type

String

Default Value

""

Remarks

This property specifies the SQS queue which will be used for all operations.

ReceivedMessageId Property (SQS Adapter)

The Id of the message received by the SQS component.

Data Type

String

Default Value

""

Remarks

This identifies the message returned by the server.

This value is also placed in the ReceivedMessageId context property. This is to ensure compatibility with other adapters that poll those context properties when filling out macros such as %SourceFileName%.

This property is not available in the Sender.

ReceivedMessageMD5 Property (SQS Adapter)

The MD5 hash of the remote message received by the SQS component.

Data Type

String

Default Value

""

Remarks

This property holds the MD5 hash of the SQS message, as returned by Amazon.

This value is also placed in the ReceivedMessageMD5 context property.

This property is not available in the Sender.

RequeueEndpoints Property (SQS Adapter)

Whether to requeue receive endpoints if the polling interval has not been reached.

Data Type

Boolean

Default Value

false

Remarks

This setting controls whether receive endpoints are requeued for later processing if the polling interval has not yet been reached. When this setting is set to No (default) each thread will block until the polling interval for the corresponding receive location is reached. If there exist more active receive locations than MaxThreads it is possible for some threads to block the execution of others since they may be waiting for a polling interval.

When this setting is set to Yes if the polling interval has not been reached the thread will not block until the polling interval is reached, and instead the endpoint will be requeued to be processed later. This lets subsequent endpoints in the queue to be processed.

If MaxThreads is set to a low value and there are a larger number of receive locations setting this to Yes will help assure that polling intervals are respected and receive locations poll in a timely manner.

The default value is No.

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Sender.

RuntimeLicense Property (SQS Adapter)

Specifies the component runtime license key.

Data Type

String

Default Value

""

Remarks

You can use the RuntimeLicense property to set the runtime key for the adapter license.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

SecretKey Property (SQS Adapter)

The Secret Key for the Amazon Web Services account.

Data Type

String

Default Value

""

Remarks

This property specifies the AWS Secret Key for the account with permissions to the SQS Queue.

SSLAcceptServerCert Property (SQS Adapter)

Instructs the component to unconditionally accept the server certificate that matches the supplied certificate.

Data Type

Certificate

Remarks

If it finds any issues with the certificate presented by the server, the adapter will normally terminate the connection with an error. You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.

This property is used to set a Public Key Certificate.

Ordinarily, the system will attempt to locate the public key in trusted certificate stores in the system registry. If a match is found, the certificate is trusted, and the process proceeds without error. If the certificate is not trusted, the adapter will report an error.

You may explicitly set a public key, either to accept a key that is not installed on the system, or to ensure that a specific key is presented. Public key certificates may be loaded from the machine registry or from file. If you click on the ellipses, a certificate selection dialog will open. To select a public key from the system registry, select the System Store tab or the User Store tab, and highlight the appropriate registry store. The list of available certificates will be shown below.

Alternatively, you may specify a public key on file. Select the PEM or Certificate File tabs to load a public key from file. You can use the browse button to examine the file system for the certificate that you wish to use. Public keys typically are stored in .CER, .DER, or .PEM files, but other formats may be used. You can click on the Open button to examine the contents of the certificate. Or, if you have a certificate stored in memory, you can write the contents of the certificate into the text box provided. Note that if you are loading a certificate from memory, the certificate must be Base-64 encoded, or the string representation of the certificate may become corrupted and uninterpretable.

Regardless of how you selected the certificate, once you hit the OK button, the adapter will attempt to verify that certificate selection. If successful, the subject of the certificate will be displayed in the property field. If the adapter was not able to verify the selection, a dialog box will appear instead detailing the verification error.

Note: You may also set the Accept Any field to Yes without opening the certificate selection dialog to force the adapter to unilaterally authenticate any server during the security handshake. It is strongly recommended that you use this only for testing purposes. Set the LogMode to Info to cause the adapter to report the server's credentials to Location.

SSLCert Property (SQS Adapter)

The certificate to use for client authentication during the SSL handshake.

Data Type

Certificate

Remarks

This property is used to assign a specific certificate for SSL client authentication.

This field is used to set a Private Key Certificate.

Private key certificates may be loaded from the registry, from files in PKCS#12 format, or from a PEM file format. If you click on the ellipses, a certificate selection dialog will open. To select a private key from the system registry, select the System Store tab or the User Store tab, and highlight the appropriate registry store. The list of certificates which have private keys will be shown below.

To select a private key certificate from a file in PKCS#12 format, select the PFX Store tab. The browse button can be used to examine the file system for PKCS#12 (.pfx or .p12) certificates. If you wish to examine the certificate, provide the password in the field provided and click on the Open button to examine the file store for certificates present. To load a certificate from PEM files, select the PEM tab. Like the PFX file selection, you can specify the password and click the Open button to examine the certificates in the PEM store, or you may paste any PEM data stored in memory.

Regardless of how you selected the certificate, once you hit the OK button, the adapter will attempt to verify that certificate selection. If successful, the subject of the certificate will be displayed in the property field. If the adapter was not able to verify the selection, a dialog box will appear instead detailing the verification error.

Timeout Property (SQS Adapter)

A timeout for the component.

Data Type

Integer

Default Value

60

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion, or an error condition is encountered.

If Timeout is set to a positive value, the adapter will wait for the operation to complete before returning control.

If Timeout expires, and the operation is not yet complete, the adapter fails with an error.

Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by Timeout seconds when data is successfully sent or received.

Optionally, the behavior of the adapter may be changed to absolute timeouts, i.e. the adapter will wait for a maximum of Timeout seconds since the beginning of the operation, without extending the timeout period during communications.

This behavior is controlled by the AbsoluteTimeout configuration setting.

The default value for the Timeout property is 60 (seconds).

TransmitBatchMode Property (SQS Adapter)

How the transmitter processes batches.

Data Type

Enumeration

Possible Values

Parallel (0)
Serial (1)


Default Value

0

Remarks

This property controls how the transmitter processes message batches:

ParallelThe adapter will process however many batches the BizTalk Message Engine sends it.

The number of maximum concurrent batches may be controlled by the MaxThreads property.

SerialThe adapter will queue batches from the BizTalk Message Engine and process them one at a time.

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Receiver.

TransportLog Property (SQS Adapter)

Tells the component where and how to report information about its operations.

Data Type

Log

Remarks

This is a Log type property which contains fields describing how and where the adapter will record information about its execution.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

URI Property (SQS Adapter)

The Uniform Resource Identifier (URI) of the send port or receive location.

Data Type

String

Default Value

""

Remarks

This property specifies a URI for the send port or receive location. Setting this property is optional.

By default the adapter will automatically generate a URI. You may choose to specify your own value here to be used in place of the generated URI.

If this value is specified it must begin with the correct prefix, as seen in the default value.

UseFIFOQueue Property (SQS Adapter)

Whether the component should use FIFO queues instead of standard queues.

Data Type

Boolean

Default Value

false

Remarks

Amazon SQS supports both standard and FIFO (First-In First-Out) queues. The order in which messages are sent and received is preserved. Messages are delivered exactly once and remain available until the receiver deletes it. FIFO queue names must end in ".fifo".

When set to True, the Queue property must end in ".fifo" and the VisibilityTimeout must not be zero. Setting VisibilityTimeout to zero when using FIFO queues prevents the adapter from being able to delete messages.

VisibilityTimeout Property (SQS Adapter)

The visibility duration for messages in the queue in seconds.

Data Type

Integer

Default Value

-1

Remarks

Visibility timeout is a mechanism defined in the SQS service which controls when existing messages in the queue become visible again after being processed. When using FIFO queues, this value also determines how long after download a message can be deleted from the queue. Because of this, a value of 0 is not allowed when UseFIFOQueue is True.

For instance if the visibility timeout is 100 seconds a message will be listed once, but will not be visible in subsequent list operations until the timeout has elapsed. This may be used to prevent duplicate processing, however in this case it is expected that the message will be deleted from the queue before the timeout expires.

A default visibility timeout is configured when a queue is created it can also be specified when a message is added or when they are listed.

The default value for VisibilityTimeout is -1, which indicates that the default timeout for the Queue should be used.

The maximum value is 43200 seconds (12 hours).

Note: To prevent duplicate downloads of messages regardless of this property value see DownloadCacheFile.

This property is not available in the Sender.

Certificate Type

The digital certificate being used.

Remarks

This type describes the current digital certificate. The certificate may be a public or private key. The fields are used to identify or select certificates.

Fields

Store
String

Default Value: "MY"

The name of the certificate store for the client certificate.

The StoreType field specifies the type of the certificate store specified by Store. If the store is password protected, specify the password in StorePassword.

Store is used in conjunction with the Subject field in order to specify client certificates. If Store has a value, and Subject is set, a search for a certificate is initiated. Please refer to the Subject field for details.

Designations of certificate stores are platform-dependent.

The following are designations of the most common User and Machine certificate stores in Windows:

MYA certificate store holding personal certificates with their associated private keys.
CACertifying authority certificates.
ROOTRoot certificates.
SPCSoftware publisher certificates.

In Java, the certificate store normally is a file containing certificates and optional private keys.

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e. PKCS12 certificate store).

If the provider is OpenSSL, the certificate store is a file containing a certificate and a private key. This property must be set to the name of the file.

StorePassword
String

Default Value: ""

If the certificate store is of a type that requires a password, this property is used to specify that password in order to open the certificate store.

StoreType
CertStoreTypes

Default Value: 0

The type of certificate store for this certificate.

The adapter supports both public and private keys in a variety of formats. When the cstAuto value is used, the adapter will automatically determine the type. This field can take one of the following values:

0 (cstUser - default)For Windows, this specifies that the certificate store is a certificate store owned by the current user.

Note: This store type is not available in Java.

1 (cstMachine)For Windows, this specifies that the certificate store is a machine store.

Note: This store type is not available in Java.

2 (cstPFXFile)The certificate store is the name of a PFX (PKCS#12) file containing certificates.
3 (cstPFXBlob)The certificate store is a string (binary or Base64-encoded) representing a certificate store in PFX (PKCS#12) format.
4 (cstJKSFile)The certificate store is the name of a Java Key Store (JKS) file containing certificates.

Note: This store type is only available in Java.

5 (cstJKSBlob)The certificate store is a string (binary or Base64-encoded) representing a certificate store in Java Key Store (JKS) format.

Note: this store type is only available in Java.

6 (cstPEMKeyFile)The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 (cstPEMKeyBlob)The certificate store is a string (binary or Base64-encoded) that contains a private key and an optional certificate.

12 (cstP7BBlob)The certificate store is a string (binary) representing a certificate store in PKCS#7 format.
13 (cstSSHPublicKeyFile)The certificate store is the name of a file that contains an SSH-style public key.
14 (cstPPKFile)The certificate store is the name of a file that contains a PPK (PuTTY Private Key).
15 (cstPPKBlob)The certificate store is a string (binary) that contains a PPK (PuTTY Private Key).
16 (cstXMLFile)The certificate store is the name of a file that contains a certificate in XML format.
17 (cstXMLBlob)The certificate store is a string that contains a certificate in XML format.
18 (cstJWKFile)The certificate store is the name of a file that contains a JWK (JSON Web Key).
19 (cstJWKBlob)The certificate store is a string that contains a JWK (JSON Web Key).
21 (cstBCFKSFile)The certificate store is the name of a file that contains a BCFKS (Bouncy Castle FIPS Key Store).

Note: This store type is only available in Java and .NET.

22 (cstBCFKSBlob)The certificate store is a string (binary or Base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format.

Note: This store type is only available in Java and .NET.

23 (cstPKCS11)The certificate is present on a physical security key accessible via a PKCS#11 interface.

To use a security key, the necessary data must first be collected using the CERTMGR adapter. The ListStoreCertificates method may be called after setting CertStoreType to cstPKCS11, CertStorePassword to the PIN, and CertStore to the full path of the PKCS#11 DLL. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the Store and set StorePassword to the PIN.

Code Example. SSH Authentication with Security Key: certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

99 (cstAuto)The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

Subject
String

Default Value: ""

The subject of the certificate used for client authentication.

When this property is set, a search is performed in the current certificate store certificate with matching subject.

If an exact match is not found, the store is searched for subjects containing the value of the property.

When setting the property to a partial subject, CN= should be omitted. For example, the following code would find the certificate with subject CN=Test Certificate, OU=People, C=US

Example (Searching with partial subject)

Control.CertSubject = "Test"

If a match is not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

If a matching certificate is found, Subject is set to the full subject of the matching certificate.

Thumbprint
String (read-only)

Default Value: ""

The thumbprint of the certificate.

This field is used to specify the thumbprint of the certificate. When there are multiple certificates in the store that have the same subject, the thumbprint will be used to distinguish between them.

Default Value: ""

A user name if authentication is to be used connecting through a firewall. If the Host is specified, the User and Password fields are used to connect and authenticate to the given Firewall. If the authentication fails, a trappable error is fired.

Constructors

Constructors are only relevant when configuring adapters in orchestrations.

public Firewall();

Log Type

A log where the component will record information about its operations.

Remarks

This describes how and where the adapter will record information describing its execution.

Fields

Location
String

Default Value: "Application"

This field describes the location where the logging information is to be written.

If the EventLog LogType has been chosen, this field must contain the name of the Event Log to which the information should be written. The default value for this field is "Application". If a value other than "Application" is set the computer must be restarted for the change to take effect. Note that the same event log must be used for all send ports and receive locations that use the same adapter.

If the File LogType has been chosen, this field must contain the location of the file to write logging information to on the file system.

The adapter also supports logging to files based on the current date and time. This allows for log files to be organized by days, months, or other intervals as specified. When specifying a log filename include a valid .NET date and time format string within the < and > characters. For instance C:\logs\sftp_<yyyyMMdd>.log or C:\logs\as2_<yyyyMMdd>T<hhmm>.log.

LogMode
LogModes

Default Value: 3

This field controls what information the adapter logs. The possible values have the following affect on the adapter's behavior:

VerboseThe adapter will report all information regarding the transport.
Info The adapter will report all major operations, as well as all warnings and errors.
WarningThe adapter will report any conditions that could result in unpredictable behavior as well as errors.
ErrorThe adapter will report all errors that prevent normal operations from completing.
FatalThe adapter will report only serious errors that cause the adapter to completely stop functioning.

LogType
LogTypes

Default Value: 1

This property controls where the adapter will log the information. The possible values have the following affect on the adapter's behavior:

NoneThe adapter will not report any logging information.
EventLogThe adapter will report all logging information to the event log. The specific event log must be defined in the Location field when this type is selected.
FileThe adapter will report all logging information to a file. The desired file must be specified in the Location field when this type has been selected.

Constructors

Constructors are only relevant when configuring adapters in orchestrations.

public Log();
public Log(LogTypes logType, string location, LogModes logMode);

Proxy Type

The proxy the component will connect to.

Remarks

When connecting through a proxy, this type is used to specify different properties of the proxy such as the Server and the AuthScheme.

Fields

AuthScheme
ProxyAuthSchemes

Default Value: 0

Use the AuthScheme field to tell the adapter which type of authorization to perform when connecting to the proxy. This is only used when the User and Password fields are set.

AuthScheme should be set to authNone (3) when no authentication is expected.

By default, AuthScheme is authBasic (0), and if the User and Password fields are set, the component will attempt basic authentication. If AuthScheme is set to authDigest (1), digest authentication will be attempted instead.

If AuthScheme is set to authProprietary (2), then the authorization token will not be generated by the adapter. Look at the configuration file for the adapter being used to find more information about manually setting this token.

If AuthScheme is set to authNtlm (4), NTLM authentication will be used. This option is only available in the SSL package.

For security reasons, setting this property will clear the values of User and Password.

AutoDetect
Boolean

Default Value: False

Tells the adapter whether or not to automatically detect and use proxy system settings, if available.

Password
String

Default Value: ""

A password if authentication is to be used for the proxy.

If AuthScheme is set to Basic Authentication, the User and Password are Base64 encoded and the proxy authentication token will be generated in the form "Basic [encoded-user-password]".

If AuthScheme is set to Digest Authentication, the User and Password fields are used to respond to the Digest Authentication challenge from the server.

If AuthScheme is set to NTLM Authentication, the User and Password fields are used to authenticate through NTLM negotiation.

Port
Integer

Default Value: 80

The TCP port for the proxy Server (default 80). See the description of the Server field for details.

Server
String

Default Value: ""

If a proxy Server is given, then the HTTP request is sent to the proxy instead of the server otherwise specified.

If the Server field is set to a Domain Name, a DNS request is initiated and upon successful termination of the request, the Server field is set to the corresponding address. If the search is not successful, an error is returned.

SSL
ProxySSLTypes

Default Value: 0

Determines when to use SSL for the connection to the proxy. The applicable values are the following:

psAutomatic (0)Default setting. The connection to the Server is SSL-enabled for 'https' URL-s, and non SSL-enabled for other URL-s.
psAlways (1)The connection is always SSL-enabled.
psNever (2)The connection is not SSL-enabled.
psTunnel (3)The connection is through a tunneling (HTTP) proxy.

User
String

Default Value: ""

A user name, if authentication is to be used for the proxy.

If AuthScheme is set to Basic Authentication, the User and Password are Base64 encoded and the proxy authentication token will be generated in the form "Basic [encoded-user-password]".

If AuthScheme is set to Digest Authentication, the User and Password fields are used to respond to the Digest Authentication challenge from the server.

If AuthScheme is set to NTLM Authentication, the User and Password fields are used to authenticate through NTLM negotiation.

Constructors

Constructors are only relevant when configuring adapters in orchestrations.

public Proxy();
public Proxy(string server, int port);
public Proxy(string server, int port, string user, string password);

Config Settings (SQS Adapter)

The adapter accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the adapter, access to these internal properties is provided through the Other property.

SQS Config Settings

DeleteOnSuspend:   Specifies whether files may be deleted from server when message is suspended.

If true, the file on the server will be deleted in accordance with the option selected in DeleteMode even if the message is suspended.

The default value is False.

DownloadCacheFileDuration:   The number of minutes that a message will remain in the download cache.

If a message is added to the DownloadCacheFile and is not returned by Amazon again within DownloadCacheFileDuration minutes, it will be removed from the cache. This can prevent the download cache file from growing too large in certain cases.

The default value is 0, meaning that messages will never be removed.

This setting is only applicable if DownloadCacheFile is set.

URL:   If set, the default URL will be overridden by this value.

By default, the adapter uses the Amazon URL for the service. Setting this will override the default value. The URL must be a valid URL for an Amazon SQS server or the adapter will default to "htttp://sqs.us-east-1.amazonaws.com/".

UseEC2RoleCredentials:   If set to true, authenticate requests with credentials obtained from the IAM role attached to the EC2 instance.

When the adapter is running within an Amazon EC2 instance, this setting can be set to true in order to automatically authenticate requests as the IAM role attached to the instance using temporary credentials obtained from the EC2 instance itself.

In order for the adapter to be able to auto-obtain authentication credentials, the EC2 instance must have an "instance profile" with an appropriate IAM role attached to it. Refer to the "Using an IAM Role to Grant Permissions to Applications Running on Amazon EC2 Instances" page in the Amazon IAM documentation for more information.

By default, this setting is false. When set to true the adapter will do the following before each request:

  1. Make a request against the EC2 instance to get the name of the role attached to it.
  2. Make a request against the EC2 instance to obtain temporary security credentials for IAM role returned in the previous call.
  3. Parse the response, automatically populating the AccessKey and SecretKey properties.
  4. Execute the original request using the temporary security credentials that were acquired.

When using this setting, set the AccessKey and SecretKey properties to dummy values (e.g., "DUMMY").

SSL Config Settings

ReuseSSLSession:   Determines if the SSL session is reused.

If set to true, the adapter will reuse the context if and only if the following criteria are met:

  • The target host name is the same.
  • The system cache entry has not expired (default timeout is 10 hours).
  • The application process that calls the function is the same.
  • The logon session is the same.
  • The instance of the adapter is the same.

SSLCipherStrength:   The minimum cipher strength used for bulk encryption.

This minimum cipher strength largely dependent on the security modules installed on the system. If the cipher strength specified is not supported, an error will be returned when connections are initiated.

Please note that this setting contains the minimum cipher strength requested from the security library.

Use this setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.

SSLEnabledCipherSuites:   The cipher suite to be used in an SSL negotiation.

The enabled cipher suites to be used in SSL negotiation.

By default, the enabled cipher suites will include all available ciphers ("*").

The special value "*" means that the adapter will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.

Multiple cipher suites are separated by semicolons.

Example values when UseInternalSecurityAPI is False (default): // The "Other" property could contain ONE of the following lines: SSLEnabledCipherSuites=* SSLEnabledCipherSuites=CALG_AES_256 SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES Possible values when UseInternalSecurityAPI is False (default) include:

If SSLEnabledProtocols is configured to use TLS 1.3 the following values are supported:

  • TLS_AES_128_GCM_SHA256
  • TLS_AES_256_GCM_SHA384

SSLEnabledCipherSuites is used together with SSLCipherStrength.

SSLEnabledProtocols:   Used to enable/disable the supported security protocols.

Used to enable/disable the supported security protocols.

Not all supported protocols are enabled by default (the value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:

TLS1.312288 (Hex 3000) (Experimental)
TLS1.23072 (Hex C00) (Default)
TLS1.1768 (Hex 300) (Default)
TLS1 192 (Hex C0) (Default)
SSL3 48 (Hex 30)
SSL2 12 (Hex 0C)

Note: TLS 1.1 and TLS1.2 support are only available starting with Windows 7.

Note: Enabling TLS 1.3 will automatically set UseInternalSecurityAPI to True.

SSLIncludeCertChain:   Whether the entire certificate chain is included in the SSLServerAuthentication event.

This setting specifies whether the transport log contains the full certificate chain. By default this value is False and only the leaf certificate will be present.

If set to True all certificates returned by the server will be present in the transport log. This includes the leaf certificate, any intermediate certificate, and the root certificate.

Note: When UseInternalSecurityAPI is set to True this value is automatically set to True. This is needed for proper validation when using the internal provider.

SSLSecurityFlags:   Flags that control certificate verification.

The following flags are defined (specified in hexadecimal notation). They can be or-ed together to exclude multiple conditions:

0x00000001Ignore time validity status of certificate.
0x00000002Ignore time validity status of CTL.
0x00000004Ignore non-nested certificate times.
0x00000010Allow unknown Certificate Authority.
0x00000020Ignore wrong certificate usage.
0x00000100Ignore unknown certificate revocation status.
0x00000200Ignore unknown CTL signer revocation status.
0x00000400Ignore unknown Certificate Authority revocation status.
0x00000800Ignore unknown Root revocation status.
0x00008000Allow test Root certificate.
0x00004000Trust test Root certificate.
0x80000000Ignore non-matching CN (certificate CN not-matching server name).

TLS12SignatureAlgorithms:   Defines the allowed TLS 1.2 signature algorithms when UseInternalSecurityAPI is True.

This setting specifies the allowed server certificate signature algorithms when UseInternalSecurityAPI is True and SSLEnabledProtocols is set to allow TLS 1.2.

When specified the adapter will verify that the server certificate signature algorithm is among the values specified in this setting. If the server certificate signature algorithm is unsupported the adapter will fail with an error.

The format of this value is a comma separated list of hash-signature combinations. For instance: // The "Other" could contain ALL of these lines: UseInternalSecurityAPI=true SSLEnabledProtocols=3072 TLS12SignatureAlgorithms=sha1-rsa,sha1-dsa,sha256-rsa,sha256-dsa The default value for this setting is "sha1-rsa,sha1-dsa,sha224-rsa,sha224-dsa,sha256-rsa,sha256-dsa,sha384-rsa,sha384-dsa,sha512-rsa,sha512-dsa".

In order to not restrict the server's certificate signature algorithm, specify an empty string as the value for this setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.

TLS12SupportedGroups:   The supported groups for ECC.

This setting specifies a comma separated list of named groups used in TLS 1.2 for ECC.

The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.

When using TLS 1.2 and UseInternalSecurityAPI is set to True, the values refer to the supported groups for ECC. The following values are supported:

  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1" (default)

TLS13KeyShareGroups:   The groups for which to pregenerate key shares.

This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange. The groups specified here will have key share data pregenerated locally before establishing a connection. This can prevent an additional round trip during the handshake if the group is supported by the server.

The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result only some groups are included by default in this setting.

Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used which is not present in this list it will incur an additional round trip and time to generate the key share for that group.

In most cases this setting does not need to be modified. This should only be modified if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072

The values are ordered from most preferred to least preferred. The following values are supported:

  • "ecdhe_x25519" (default)
  • "ecdhe_x448"
  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1"
  • "ffdhe_2048" (default)
  • "ffdhe_3072" (default)
  • "ffdhe_4096"
  • "ffdhe_6144"
  • "ffdhe_8192"

TLS13SignatureAlgorithms:   The allowed certificate signature algorithms.

This setting holds a comma separated list of allowed signature algorithms. Possible values are:

  • "rsa_pkcs1_sha256" (default)
  • "rsa_pkcs1_sha384" (default)
  • "rsa_pkcs1_sha512" (default)
The default value is rsa_pkcs1_sha256,rsa_pkcs1_sha384,rsa_pkcs1_sha512. This setting is only applicable when SSLEnabledProtocols includes TLS 1.3.
TLS13SupportedGroups:   The supported groups for (EC)DHE key exchange.

This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange. This setting should only be modified if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_x448,ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1,ffdhe_2048,ffdhe_3072,ffdhe_4096,ffdhe_6144,ffdhe_8192

The values are ordered from most preferred to least preferred. The following values are supported:

  • "ecdhe_x25519" (default)
  • "ecdhe_x448" (default)
  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1" (default)
  • "ffdhe_2048" (default)
  • "ffdhe_3072" (default)
  • "ffdhe_4096" (default)
  • "ffdhe_6144" (default)
  • "ffdhe_8192" (default)

General Config Settings

AbsoluteTimeout:   Determines whether timeouts are inactivity timeouts or absolute timeouts.

If AbsoluteTimeout is set to True, any method which does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

LocalHost:   The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

The LocalHost configuration contains the name of the local host as obtained by the Gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the adapter initiate connections (or accept in the case of server adapters) only through that interface.

If the adapter is connected, the LocalHost configuration shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

TcpNoDelay:   Whether or not to delay when sending packets.

When true, the socket will send all data that is ready to send at once. When false, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this config is set to false.

UseInternalSecurityAPI:   Whether or not to use the system security libraries or an internal implementation.

When set to False, the adapter will use the system security libraries by default to perform cryptographic functions where applicable. In this case, calls to unmanaged code will be made. In certain environments, this is not desirable. To use a completely managed security implementation, set this setting to True.

Setting this configuration setting to True tells the adapter to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to False by default. On Linux/macOS, this setting is set to True by default.

If using the .NET Standard Library, this setting will be True on all platforms. The .NET Standard library does not support using the system security libraries.

Note: This setting is static. The value set is applicable to all adapters used in the application.

When this value is set, the product's system dynamic link library (DLL) is no longer required as a reference, as all unmanaged code is stored in that file.

Supported Macros

The adapter also supports the following Macros. These values are not case sensitive and would be supplied to a property in the form %MacroName%.

TempThis is resolved to the full path to the system's temporary directory. MessageIDGlobally unique identifier (GUID) of the message in BizTalk Server. SourceFileNameThe original file name. This includes the extension and excludes the file path, for example, Sample.xml SourceFileNameNoExtThe original file name without the extension or file path, for example, Sample RemoteFileNameThe name of the file as it was uploaded to the remote server. This includes the extension and excludes the file path, for example, Sample.xml. Valid only for AS3, FTP, and SFTP Send Adapters. DestinationPartyName of the destination party. DestinationPartyQualifierQualifier of the destination party. SourcePartyName of the source party. SourcePartyQualifierQualifier of the source party. DateTime:CustomFormatThis special value allows you to specify your own custom time format. For instance DateTime:yyyy would be resolved to the 4 digit year. DateThe date format yyyy-MM-dd. DateTimeThe date format yyyy-MM-ddThhmmss. TimeThe date format hhmmss. DateTime_BTS2000The date format yyyyMMddhhmmssf. DateTime.TZThe date format yyyy-MM-ddThhmmsszzz. Time.TZThe date format hhmmsszzz. Property#<Schema>#<Name>This special value allows you to include a property from the incoming message. For instance "PROPERTY#http://schemas.microsoft.com/BizTalk/2003/system-properties#ReceivePortName" would resolve to the ReceivePortName property of the message.
