Suppressing WebSphere MQ for z/OS dumps using z/OS DAE

We can suppress SVC dumps that duplicate previous dumps. The MVS Diagnosis: Tools and Service Aids manual gives details about using z/OS dump analysis and elimination (DAE).

To support DAE, WebSphere MQ for z/OS defines two variable recording area (VRA) keys and a minimum symptom string. The two VRA keys are:

• KEY VRADAE (X'53'). No data is associated with this key.

• KEY VRAMINSC (X'52') DATA (X'08')

WebSphere MQ for z/OS provides the following data for the minimum symptom string in the system diagnostic work area (SDWA):

• Load module name

• CSECT name

• Abend code

• Recovery routine name

• Failing instruction area

• REG/PSW difference

• Reason code

• Component identifier

• Component subfunction

Dumps are considered duplicates for the purpose of suppressing duplicate dumps if eight (the X'08' from the VRAMINSC key) of the nine symptoms are the same.
