Periodically monitor for SYSZATR RESTART resource contention with
the DISPLAY GRS,CONTENTION command. If you detect contention, Follow
the action specified in the system logger service return and reason
codes shown in message ATR248E or ATR249E. See the IXGWRITE return
and reason codes in z/OS MVS Programming: Authorized Assembler Services Reference EDT-IXG.
If the action in the return and reason code does not resolve the
contention, or if you cannot detect the cause of the contention:
- Capture a dump of RRS, system logger, and GRS on the system that
is holding the resource.
- Recycle RRS on the holding system to free the resource.
Note: If the issue that causes the holder to hang persists,
the resource contention can continue until the issue is resolved.
Search
problem reporting databases for a fix for the problem. If no fix exists,
report the problem to the IBM® Support
Center and provide the dump, system logs, and formatted LOGREC data
set. (A symptom record is created on the system experiencing the failure
and stored in the LOGREC data set.)
