Using the Rollback Options panel

Use the Rollback feature to return an AR/CTL managed participant in the environment to the latest checkpoint.

Warning

Notes

  • Rollback processing is implemented for non IMS environments only.
  • VSAM resources do not participate in AR/CTL rollback processing.

The AR/CTL ROLLBACK processing options define the participants for the rollback. These participants can be:

  • Db2 resources
  • ASAM and QSAM resources
  • AR/CTL managed application program user areas
  • AR/CTL managed subprogram virtual storage areas

The application program requests the AR/CTL rollback services in either of these scenarios:

  • The application cannot continue processing in the current unit of work (UOW).
  • The work performed in the current partially complete UOW has to be rolled back to the latest checkpoint.

Rollback options allow you to control whether AR/CTL automatically triggers a rollback for a job step.

This section describes the processing options on the Rollback Options panel.
