Re: Recovering from a hosed up CUME install

Actually what he says about the subsystem descriptions may, or may not, be
true. Here's the catch: If you do what I used to do, which is copy over
qbatch subsystem description from a backup library prior to the upgrade
after every upgrade then you'll notice you have to keep doing this because
you lost your change. Why? Because somewhere in the internals of the
subsystem description is it's release level and if it's really old (V2 I
think) it cannot upgrade it during the OS upgrade so it replaces it. I
have thousands of job queue entries in QBATCH. Finally called IBM on this
and the workaround is to recreate my subsystem description from scratch
(or manually add the thousands of job descriptions to the new qbatch). I
wrote a program to retrieve the attributes of the backup qbatch and create
a new qbatch. Now IBM updates it fine and I don't lose my job queue
entries. Again, I only had to run the program once and every os upgrade
since then has been fine.

Perhaps if you are one of those shops that tried something clever and
restored a machine onto another machine because you were more than n-2
levels behind or just would rather spend a month cleaning up problems than
a day doing two upgrades to get there the official way, then you may have
also fell into this trap.
