Automatic restart step adjustment

The user normally specifies the step at which the restart must begin, either in a DO IFRERUN statement in the job scheduling definition, or in the Restart window used to manually issue a restart request.

If, however, the restart job step chosen by the user is not recoverable, the Restart Step Adjustment facility automatically can replace the user-specified restart step with the closest recoverable job step prior to the requested restart step, and issues an appropriate message to notify the user of the change.

The facility thereby enables the user to choose the restart step on the basis of application considerations without worrying if the step is actually recoverable.

By default, the Restart Step Adjustment facility is operational and performs step adjustment as needed. However, step adjustment can be disabled in either of the following ways:

• by specifying the appropriate parameter in the Control-M/Restart PARM library
  For more information, see [NO]STEPADJUST parameters.
• by specifying N (No) in the STEP ADJUSTMENT field in the Rerun/Restart or Confirm Restart window

If step adjustment is needed but step adjustment was disabled, job restart is terminated with a non-zero return code.
