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.
