I was bringing down an ISV product that monitors our DASD. JES2 was
suspended not dead. ok now the truthI was bringing down this
software on one system and started to bring it down on the other before
the first shutdown was complete. This software issues reserves for some
reason and I think that since 2 shutdowns were taking place at the
sometime had something to do with it. It was a timing thing.

Subject: JES2 Checkpoint Lock Held
Hi,
I had a problem where one system in the MAS had the JES2 chkpt lock
held. There are 2 systems in the MAS. In this situation can you reset
the lock being held without doing further damage ? Please advise.
Thanks
Dean

The big question is WHY did the other system have the lock held? If
the other system is DEAD and DOWN (i.e. an IPL is going to be done on
it), then resetting the checkpoint lock is OK. If the other system is
suspended for some reason (such as lack of CPU due to being in a
low-priority LPAR or DASD reserve or ???), then resetting the lock might
cause data corruption on the SPOOL. JES2 will likely recover from this,
but the affect job/tso/stc might die.
