Restarting and Recovering Real-time Sessions

You can resume a stopped or failed real-time session. To resume a session, you must restart or recover the session. The Integration Service can recover a session automatically if you enabled the session for automatic task recovery.

The following sections describe recovery information that is specific to real-time sessions.
