Re: Questions on ECB status when task abends
In [EMAIL PROTECTED], on 08/23/2005 at 02:32 PM, Vic Petrone [EMAIL PROTECTED] said: The main task is waiting on an ECB to be posted by an external event. Does the ECB list include the ECB for the subtask? 1) Will the main task's ESTAE exit now receives control even if it's still waiting on the ECB? Not unless the main task is ABENDing. 2) If so, what is the status of the ECB that was being waited upon? Why would it change? 3) Can the main task's ESTAE exit retry and then re-issue the wait on this ECB if it hasn't been posted yet? If there is an ABEND of the main task, the ESTAE requests a retry and the retry routine determines that it is safe, then yes. You might have to clean up the ECB. Why not just include the subtask ECB in the wait list? -- Shmuel (Seymour J.) Metz, SysProg and JOAT ISO position; see http://patriot.net/~shmuel/resume/brief.html We don't care.

Re: Questions on ECB status when task abends
Thank you both for your replies. No, I'm not using EXTR nor was the STEP specified on the ABEND. I understand the problem. After the subtask percolates, the system post the main task's ECB with the subtask's completion code. The abend will not interrupt the main task. The main task can check the ECB when it needs to and then take appropriate action.

Questions on ECB status when task abends
Hi, I have a main task and subtask running. The main task has an ESTAE established and the subtask has an ESTAI established. The subtask runs asynchronously with the main task. The main task is waiting on an ECB to be posted by an external event. During this wait the subtask abends, the abend is trapped by the ESTAI exit which then cleans up and percolates. 1) Will the main task's ESTAE exit now receives control even if it's still waiting on the ECB? 2) If so, what is the status of the ECB that was being waited upon? 3) Can the main task's ESTAE exit retry and then re-issue the wait on this ECB if it hasn't been posted yet?

Abends are not percolated to the parent task under any circumstances, so the answer to 1) is no. On the other hand, if you meant to ask about the main task's ETXR exit, the answer to 1) would be yes. The ETXR runs as an IRB which interrupts the waiting RB, and when the ETXR completed, the main task would still be waiting on the ECB. Jim Mulder z/OS System Test IBM Corp.
