Stopping/resuming batch extract execution

File-AID/RDX provides the ability to identify a checkpoint in an extract request that will stop the execution of the extract in a controlled manner. Stop a checkpoint enabled extract at a pre-determined checkpoint or any time during execution with a z/OS MODIFY command (see Stop Extract Execution with z/OS Operator MODIFY Command). In all cases, processing on the object currently being extracted will complete before the checkpoint is taken and a controlled stop occurs. After the controlled stop, submit the extract request again to resume the extract execution from the checkpoint.

Use this functionality when you anticipate a long running extract that might not complete within your site’s constraints or when executing complex related extracts.

For more information, see Checkpoint-Resumption.

Stop Extract Execution with z/OS Operator MODIFY Command

To stop the execution of an extract in a controlled manner without a pre-determined checkpoint, enable Checkpoint/Resumption and specify the Checkpoint Data File for the extract request. Then, during extract execution, use the z/OS MODIFY command with parameter NOW.

Important

The MODIFY command requires proper OPERATOR authority.

The verb MODIFY can be abbreviated, F.

Syntax:

F jobname,NOW

Important

If you cancel an extract without Checkpoint/Resumption Enabled, the extract will be incomplete and will not be usable for extract resumption or load.
