Characteristics of message adapters

Event triggers

Messages can be used as source event triggers for a map.

Wildcards

Wildcards can be used for message identifiers. If the message identifier is specified as a wildcard, the value of that wildcard is derived from the value of the message identifier of a message event trigger or from a file source with a wildcard in its name.

OnFailure, and Retry settings

• The OnFailure option for a source or target depends on the specific messaging adapters. For example, for IBM® WebSphere® MQ the source rollback option includes an option to place the source message on an error queue.
• The Retry option for a source or target depends on the specific messaging adapters. In general, the command option for the adapter must be valid on the computer where the Launcher is installed. If a connection to a queue cannot be made because the specified queue is not available, you will get a source not available message or a target not available message. If connection parameters are valid, but the message is unavailable due to, for example, a connection limit that has been reached or the message is locked, the retry will be attempted.
