Console messages and dumps
Look for:
- Outstanding WTOR messages
- IXGxxx messages
- Allocation, catalog and HSM error messages
- IO errors for log stream data sets and LOGR couple data sets
- IXCxxx messages, indicating problems with the coupling facility structure or couple data sets.
- 1C5 abends, and other abends from the IXGLOGR address space.
Log stream data sets are of the form IXGLOGR.stream_name.Annnnnnn.
The high level qualifier (IXGLOGR) may be different if the HLQ parameter
was specified when the log stream was defined.
Explanations of MVS logger reason codes which are shown in CICS and MVS messages and traces are in the IXGCON macro and in z/OS MVS Programming: Assembler Services Reference ABE-HSP .
