If a PowerCenter Integration Service process becomes unavailable, the Service Manager tries to restart it or fails it over to another node based on the shutdown mode, the service configuration, and the operating mode for the service. Restart and failover behavior is different for services that run on a single node, primary and backup nodes, or on a grid.
When the PowerCenter Integration Service fails over, the behavior of completed tasks depends on the following situations:
If a completed task reported a completed status to the PowerCenter Integration Service process prior to the PowerCenter Integration Service failure, the task will not restart.
If a completed task did not report a completed status to the PowerCenter Integration Service process prior to the PowerCenter Integration Service failure, the task will restart.
