Responding when CANCEL Is the Only Option

Under the following circumstances, CANCEL is the only option available to the operator:

• WAIT is not an option on the IEF238D message
• There are no offline devices to satisfy the request, or all offline devices have been eliminated for one of the following reasons:
  • Job reserve
  • z/OS or other vendor software
  • TPCEDLXT exit routine
  • Overgenned status
  • Externally DEDICATED status
  • NOT AVAILABLE status

When CANCEL is the only option available to the operator, you can have TPCF automatically respond CANCEL by specifying SETOPTION AUTOREPLY=(ON,NOWAIT=(CANCEL=YES)). This is the default setting.

Note: If CANCEL=NO is specified, then the MIM2060 WTOR is issued with CANCEL as the only option. The operator is forced to reply CANCEL. Until the operator replies CANCEL, the job in allocation recovery holds the tape device allocation resources that are serialized across the MIMplex. Tape allocations on all systems in the MIMplex experience delays until the operator replies CANCEL.

We recommend that you specify CANCEL=YES unless you have a specific reason for not doing so.
