Fast step restart

When you invoke the step restart function, you are required to go through several panels before the step restart is actually run. For example, the STEP RESTART SELECTION LIST panel (EQQMERSL) is displayed for you to select the restart range. The CLEANUP ACTION LIST panel (EQQMCMDL) might be displayed to let you change the cleanup action list. The editing panel (EQQMMJCL) might be displayed to let you edit the JCL during restart. Also, confirmation panels (EQQMERJP, EQQMERTP) are shown. To skip these panels, leaving all choices as defaults, you can invoke the Fast Step Restart function.

Like the Step Restart function, Fast Step Restart lets you restart a job or a started task at the step level and performs the appropriate cleanup actions. Unlike Step Restart, it lets you do it with a single command. Fast Step Restart is based on the same simulation mechanism from the history of the previous runs as the Step Restart function. The EQQCLEAN step is added and performs the simulation of return codes, cleanup actions, and resolution of GDGs, but defaults are used where selections were allowed with the Step Restart. For details, see Return code simulation logic, Data set cleanup, and GDG resolution.

The Fast Step Restart function can be requested for any operation, which ran at least once, by issuing the FSR command from any of the following operation lists in the MODIFY CURRENT PLAN panels:
  • Ended-in-error operation list
  • Operation list
  • Operation displayed when you request to rerun an occurrence
Note: The first time you issue the FSR command, message EQQM601I (Scheduler has requested needed JOBLOG information to process the command) is displayed if the JOBLOG information is not yet available to data store. In this case, you must issue the FSR command again. Message EQQM676I (Fast step restart is being processed) is then displayed and, unless other warnings are issued, the operation is finally completed.
