Interactions supported with commit mode and sync level combinations

The interactions that are supported by the IMS TM resource adapter depend on the combination of commit mode and sync level that you choose.

The following combinations of commit mode and sync level are supported by the IMS TM resource adapter:
  • Commit mode 1 with sync level NONE

    This combination is used for non-transactional interactions. For non-conversational applications, use the SYNC_SEND_RECEIVE interaction. For conversational applications, use the SYNC_SEND_RECEIVE or, optionally, the SYNC_END_CONVERSATION interaction.

  • Commit mode 1 with sync level CONFIRM

    This combination is used for non-transactional interactions. For non-conversational applications, use the SYNC_SEND_RECEIVE interaction. For conversational applications, use the SYNC_SEND_RECEIVE or, optionally, the SYNC_END_CONVERSATION interaction.

  • Commit mode 0 with sync level CONFIRM

    This combination is used for non-transactional SYNC_SEND_RECEIVE, SYNC_SEND, SYNC_RECEIVE_ASYNCOUTPUT_SINGLE_NOWAIT, SYNC_RECEIVE_ASYNCOUTPUT_SINGLE_WAIT and SYNC_RECEIVE_CALLOUT interactions.

    Tip: Commit mode 0 is supported only for non-conversational applications that are running on TCP/IP connections.

For commit mode 1 interactions, the IMS TM resource adapter automatically provides the synchronization level when it communicates with IMS Connect. The synchronization level can also be set explicitly by the Java™ client by using the setSyncLevel(int) method to NONE or CONFIRM. The default sync level is NONE. You can set the interaction verb to SYNC_SEND_RECEIVE without setting the sync level.

For commit mode 0 interactions, only the CONFIRM sync level is supported.

The setSyncLevel(int) method throws an exception for any invalid combination of commit mode and sync level.
