I've had a question from a customer running Scheduler V2.1B who states that when a SCHEUDLE ABORT is done, the postfunction of the job sometimes is not executed and sometimes is executed only half. They use the postfunction to activate pagers to notify the operators. They noticed that sometimes, if they abort the job the postfunction is not executed at all, and sometimes, funny enough, that the postfunction is being activated. This led to a situation where the pagers were activated, but the main job was already gone. What is the intended behaviour of abort concerning postfunctions? Is it possible to specify that you do want the postfunction executed, no matter what happened to the main step? Cheers, Willem

| 1213.1 | kills the process that would have executed them | RUMOR::FALEK | ex-TU58 King | Thu Feb 13 1997 19:17 | 12 |
Since the pre- main and post- functions all are executed in the same
process, (if they didn't, it could cause problems with things like
device allocations) and SCHED ABORT kills the main process, the
postfunction generally does not execute. This is documented somewhere.
Postfunctions should *not* be treated as a reliable mechanism that is
guaranteed to always execute. For example, if you put the line
$ logoff
in the middle of a job's command procedure, or if you do $ STOP/ID on
a running job, then the postfunction won't execute.

| 1213.2 | status of a job excplained | HLFS00::ERIC_S | Eric Sonneveld MCS - B.O. IS Holland | Mon Feb 24 1997 10:04 | 12 |
The official job run sequence is: If there is a pre function - execute it If status ok then execute main function, if status is failed then stop execution, end status of the job is the status of the (failed) prefunction. After execution of main function and there is a post function run this (in all cases, you can override the main status always in the post function). If there is no post function the end status of the job is the status of the main funtion If there was a post function the end status of the job is the status of the post function. Eric | |||||
