Safe Mode

Safe Mode

In safe mode, access to the PowerCenter Integration Service is limited. You can configure the PowerCenter Integration Service to run in safe mode or to fail over in safe mode:
  • Enable in safe mode. Enable the PowerCenter Integration Service in safe mode to perform migration or maintenance activities. When you enable the PowerCenter Integration Service in safe mode, you limit access to the PowerCenter Integration Service.
    When you enable a PowerCenter Integration Service in safe mode, you can choose to have the PowerCenter Integration Service complete, abort, or stop running workflows. In addition, the operating mode on failover also changes to safe.
  • Fail over in safe mode. Configure the PowerCenter Integration Service process to fail over in safe mode during migration or maintenance activities. When the PowerCenter Integration Service process fails over to a backup node, it restarts in safe mode and limits workflow activity and access to the PowerCenter Integration Service. The PowerCenter Integration Service restores the state of operations for any workflows that were running when the service process failed over, but does not fail over or automatically recover the workflows. You can manually recover the workflow.
    After the PowerCenter Integration Service fails over in safe mode during normal operations, you can correct the error that caused the PowerCenter Integration Service process to fail over and restart the service in normal mode.
The behavior of the PowerCenter Integration Service when it fails over in safe mode is the same as when you enable the PowerCenter Integration Service in safe mode. All scheduled workflows, including workflows scheduled to run continuously or start on service initialization, do not run. The PowerCenter Integration Service does not fail over schedules or workflows, does not automatically recover workflows, and does not recover client requests.
