Monitoring information
REQ. QU Average number of requests waiting for the release of a buffer
management table or currently using a buffer management table.
If the request queue is always long, this means that there are too
few buffers compared to the number of CMS calls, i.e. that the
number of buffer management tables should be increased. If the
maximum number of buffer management tables is already being
used, the PVS can be subdivided into smaller pubsets. The desired
number of buffer management tables can be specified at system
setup using the BMTNUM parameter.
SER. QU Average number of requests waiting for a serialization lock for exclu-
sively searching a suitable buffer management table or currently
using this lock (relevant for system engineers)
BLOCK QU Average number of requests waiting for an exclusive lock for
processing a block of a partition or currently using this lock (a
partition corresponds to a user ID)
USERID QU Average number of requests waiting for a partition lock or currently
using this lock. This lock is not normally exclusive.
CE QU Average number of requests waiting for an exclusive lock for
processing a catalog entry of a block of a partition or currently using
this lock

pubsets
SMP QU Average number of requests to the catalog index for system-
managed pubsets
