How about a dynamic activate that succeeded but a component (catalog) that 
doesn't listen to the ENF signal that a UCB was removed, that had stored the 
old address in a common control block and *after* the activate abends CAS with 
very frequent 0C4s trying to touch the (now freemained) storage. While IBM took 
an apar on that 4 or 5 years ago, when we were hit with this problem and had an 
unscheduled installation wide outage because of it, the apar was closed SUG or 
some such and as far as I know it is still NOT fixed. During the escalation I 
was assured that IBM would fix it (in 1.13 at the latest), but the apar still 
doesn't say that the requirement was fulfilled. And that's IBM code.

And don't tell me how to move a catalog. The documentation how to do it if you 
delete and then re-add the UCB to your config under a different name was 
written due to our outage. I think the HCD book now has a footnote that says 
'don't do it'.
