Jeff answered most of your questions, I'll deal with the QUSRSYS and recoverability.

Yes the system is completely recoverable with the SWA on QUSRSYS, in fact I have performed many recovery tests using BRMS, and in many ways it works better than the manual recovery. Were you using BRMS for the SWA processing? If not I suspect that the checkpoint processing my not have been done quite right leaving some objects out of synchronization.

It is also true that a slowdown in normal activity will make the SWA work much better as well. The best situation is to be able to quiesce the the system for a short time (about 5 minutes in my experience) while the checkpoints are taken, particularly with *SYNCLIB or *SYSDFN check points.

Hi Jeff

thanks for sharing, I'm following this with some interest.

2 questions:

- You say all the rest are save while active - what kind of save while
active are you doing ? What is the sync type ? Are you using a message
queue monitor to restart normal processing ?

- By my reckoning QUSRSYS will get saved via SWA. Is this going to be
OK in a recovery scenario ? My experience is not good using SWA on
QUSRSYS.
