Acknowledging a procedure allows you to manually change the status of procedures that either failed or have errors in order to control where the next attempt to run the procedure will start. Procedures with a status of *CANCELED, *FAILED, or *COMPERR can be acknowledged (set to *ACKCANCEL, *ACKFAILED, or *ACKERR, respectively) to indicated you have investigated the problem steps and understand the implications.
There is one exception to this for a virtual switch procedure. If a problem occurs in any step within the range performed while the replication status for the application group indicates virtual switch activity (starting, testing, or recovering) and the virtual switch procedure fails or is canceled, you cannot acknowledge the failed or canceled procedure. The procedure must be resumed.
A procedure of *CANCELED or *FAILED allows you to rerun the procedure from its first step. Once acknowledged, a procedure with either of these statuses cannot be resumed from the point where the procedure ended. This is appropriate when you have determined that your environment will not be harmed if the next attempt to run starts at the first step.
A *COMPERR procedure that is acknowledged (*ACKERR) can never be resumed because the procedure completed. By acknowledging a procedure with this status, you are confirming the problems have been reviewed.
The last run of a procedure with a status of *ACKCANCEL or *ACKFAILED and the last run of the set of start/end/switch procedures can be returned to their previous status (*CANCELED or *FAILED, respectively). The next attempt to run the procedure will resume at the failed or canceled step or at the first step that has not been started.
Important! Before changing status of a procedure, it is important that you evaluate and understand the effect of the partially performed procedure on your environment. Changing procedure status does not reverse the actions taken by preceding steps that completed or the actions performed by other asynchronous jobs which did complete the same step and then processed subsequent steps. It may not be appropriate for the next run of the procedure to begin with the first step, for example, if the failure occurred in a step which synchronizes data or changes states of MIMIX processes. Likewise, it may not be appropriate to return to the previous status to resume a procedure run was not recently run.
To change the status of a procedure, do the following:
From the Work with Procedure Status display type
13(Change status) next to the failed or canceled procedure you want and press Enter.The Change Procedure Status (CHGPROCSTS) display appears. Specify the value you want for the Status prompt and press Enter.
If you specified *ACK in Step 2, the Start time prompt appears with *ALL specified for Start time (STARTTIME). To acknowledge all previously failed or canceled runs of the selected procedure, press Enter.
