Does anyone on the list remember advice that a change occurred with z/OS 1.11
that might result in UCATs being allocated to the CATALOG task under z/OS 1.11
early on in IPL, when this almost certainly as not happening under z/OS 1.10?
We have been upgrading a 3-LPAR non-SYSPLEX system from z/OS 1.10 to 1.11, and
didn't have any problems with the first two, but in the last one ended up in a
VARY OFFLINE PENDING situation when a volume was varied offline.
The system is not a sysplex but does share several volumes across the LPARS.
A F CATALOG,UNALLOCATE(catname) command did unallocate the catalog and the
allocation against the volume that we wanted t take offline.
...
At least during normal system operation a UCAT is only allocated if
there is a reference that requires it to be opened, and it tends to stay
open and allocated at that point even if not needed. If you are certain
it is not needed, try closing the UCAT first
(F CATALOG,CLOSE(catname) and then see if you can UNALLOCATE it. You
can't un-allocate while it is still open.
