WebSphere MQ for z/OS diagnostic information
WebSphere MQ for z/OS functional recovery routines use z/OS services to provide diagnostic
information to help you in problem determination.
The following z/OS services provide diagnostic information:
- SVC dumps
- The WebSphere MQ abend completion code X'5C6' uses the z/OS SDUMP
service to create SVC dumps. The content and storage areas associated with
these dumps vary, depending on the specific error and the state of the queue
manager at the time the error occurred.
- SYS1.LOGREC
-
Entries are requested in the SYS1.LOGREC data set at the time of
the error using the z/OS SETRP service. The following are also recorded
in SYS1.LOGREC:
- Subsystem abnormal terminations
- Secondary abends occurring in a recovery routine
- Requests from the recovery termination manager
- Variable recording area (VRA) data
- Data entries are added to the VRA of the SDWA by using a z/OS VRA defined
key. VRA data includes a series of diagnostic data entries common to all WebSphere MQ for z/OS abend
completion codes. Additional information is provided during initial error
processing by the invoking component recovery routine, or by the recovery
termination manager.
