Rules and Guidelines for Session Recovery

Rules and Guidelines for Session Recovery

Use the following rules and guidelines when recovering sessions:
  • The Integration Service creates a new session log when it runs a recovery session.
  • A session reports performance statistics for the last successful run.
  • You can recover a session containing a transformation that uses the random number generator (RAND) function if you provide a seed parameter.
  • During session recovery, the PowerCenter Integration Service resets mapping variables to the start value.
