Documentation
Definition
This ratio shows how many lock requests are not propagated to XES and coupling facility because of global locking optimizations.
It is computed as
100 * (QTGALSLM - QTGALPLK) / QTXALOCK
where
QTGALSLM:
The number of lock requests propagated to MVS XES synchronously (that is, under the user's execution unit).
This count includes both L-locks and P-locks. It is not incremented if the request is suspended before going to XES.
QTGALPLK:
The number of lock requests for P-locks.
QTXALOCK:
Lock request count.
