PowerCenter Integration Service Behavior

PowerCenter Integration Service Behavior

Safe mode affects PowerCenter Integration Service behavior for the following workflow and high availability functionality:
  • Workflow schedules. Scheduled workflows remain scheduled, but they do not run if the PowerCenter Integration Service is running in safe mode. This includes workflows scheduled to run continuously and run on service initialization.
    Workflow schedules do not fail over when a PowerCenter Integration Service fails over in safe mode. For example, you configure a PowerCenter Integration Service to fail over in safe mode. The PowerCenter Integration Service process fails for a workflow scheduled to run five times, and it fails over after it runs the workflow three times. The PowerCenter Integration Service does not complete the remaining workflows when it fails over to the backup node. The PowerCenter Integration Service completes the workflows when you enable the PowerCenter Integration Service in safe mode.
  • Workflow failover. When a PowerCenter Integration Service process fails over in safe mode, workflows do not fail over. The PowerCenter Integration Service restores the state of operations for the workflow. When you enable the PowerCenter Integration Service in normal mode, the PowerCenter Integration Service fails over the workflow and recovers it based on the recovery strategy for the workflow.
  • Workflow recovery.The PowerCenter Integration Service does not recover workflows when it runs in safe mode or when the operating mode changes from normal to safe.
    The PowerCenter Integration Service recovers a workflow that failed over in safe mode when you change the operating mode from safe to normal, depending on the recovery strategy for the workflow. For example, you configure a workflow for automatic recovery and you configure the PowerCenter Integration Service to fail over in safe mode. If the PowerCenter Integration Service process fails over, the workflow is not recovered while the PowerCenter Integration Service runs in safe mode. When you enable the PowerCenter Integration Service in normal mode, the workflow fails over and the PowerCenter Integration Service recovers it.
    You can manually recover the workflow if the workflow fails over in safe mode. You can recover the workflow after the resilience timeout for the PowerCenter Integration Service expires.
  • Client request recovery. The PowerCenter Integration Service does not recover client requests when it fails over in safe mode. For example, you stop a workflow and the PowerCenter Integration Service process fails over before the workflow stops. The PowerCenter Integration Service process does not recover your request to stop the workflow when the workflow fails over.
    When you enable the PowerCenter Integration Service in normal mode, it recovers the client requests.
