Re: BRMS - full save with least amount of restricted time

[Jim Oberholtzer <midrangel@xxxxxxxxxxxxxxxxx>]

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.
