Stopping and Aborting Overview

Stopping and Aborting Overview

You can stop or abort a task, workflow, or worklet at any time.
You can stop or abort a session just as you can stop or abort any task. You can also abort a session by using the ABORT() function in the mapping logic. Session errors can cause the Integration Service to stop a session early. You can control the stopping point by setting an error threshold in a session, using the ABORT function in mappings, or requesting the Integration Service to stop the session. You cannot control the stopping point when the Integration Service encounters fatal errors, such as loss of connection to the target database.
If a session fails as a result of error, you can recover the workflow to recover the session.
When you stop a workflow, the Integration Service tries to stop all the tasks that are currently running in the workflow. If the workflow contains a worklet, the Integration Service also tries to stop all the tasks that are currently running in the worklet. If it cannot stop the workflow, you need to abort the workflow.
The Integration Service can stop the following tasks completely:
  • Session
  • Command
  • Timer
  • Event-Wait
  • Worklet
When you stop a Command task that contains multiple commands, the Integration Service finishes executing the current command and does not run the rest of the commands. The Integration Service cannot stop tasks such as the Email task. For example, if the Integration Service has already started sending an email when you issue the stop command, the Integration Service finishes sending the email before it stops running the workflow.
The Integration Service aborts the workflow if the Repository Service process shuts down.
