Recovering Real-time Sessions

Recovering Real-time Sessions

If you enabled session recovery, you can recover a failed or aborted session. When you recover a session, the Integration Service continues to process messages from the point of interruption. The Integration Service recovers messages according to the real-time source.
The Integration Service uses the following session recovery types:
  • Automatic recovery.
     The Integration Service restarts the session if you configured the workflow to automatically recover terminated tasks. The Integration Service recovers any unprocessed data and restarts the session regardless of the real-time source.
  • Manual recovery.
     Use a Workflow Monitor or Workflow Manager menu command or
    pmcmd
     command to recover the session. For some real-time sources, you must recover the session before you restart it or the Integration Service will not process messages from the failed session.
