>I would NEVER want to see automation of a FORCE >(other than maybe a FORCE ARM. Maybe.).
Clearly you're not running AVM (that archaic component called availability manager that IMS shops use and that was around way before ARM): *That* address space doesn't even have a shutdown command! It cannot be canceled, you *have to* force arm it! If the thing would make itself invisible on a D A,L command, it wouldn't be so bad at system shutdown, but it is always visible and causes problems for operating. You wouldn't believe how often I told them: Keep it up, don't shut it down, they will start experimenting every time. :-( (And no, IBM doesn't think they should provide a 'clean' shutdown command! I tried and got the typical 'This is working as designed - we don't care.') >I've had some seemingly good results by issuing a cancel three times, >waiting about a minute between each command. Almost like each cancel >takes out a layer. It does. Kinda sorta. Jim, please step in, because I am even more fuzzy on this. Here goes: In the ninetees RTM was rewritten to avoid the address space hang problems after cancel (usually deadlocks between terminating TCBs). From then on when an address space wouldn't come down, the bottom tcb is always the one holding off shutdown, as the top ones will not terminate anymore until all daughters are gone. In some cases repeated CANCELs go and cause re-entry to RTM. RTM then knows to 'escalate' the termination, taking away control from the recovery routine that is just supposed to be running. This doesn't always work, as the cancel command isn't necessarily propagated down to the bottom tcb a second or third time. I am not really clear anymore *why* this sometimes works and sometimes doesn't. My experience with the callrtm program has always been that I needed to run the same program several times to see a result. Sometimes even in combination callrtm'ing the top application tcb and the bottom tcb. So yes, in a way each cancel command takes away a 'layer'. Regards, Barbara -- Psssst!
