When SVC dumps are not produced
Under some circumstances, SVC dumps are not produced. Generally, dumps are suppressed because of time or space problems, or security violations. The list below summarizes other reasons why SVC dumps might not be produced:
- The z/OS serviceability level indication processing (SLIP) commands suppressed the abend.
The description of IEACMD00 in the MVS Initialization and Tuning Reference manual lists the defaults for SLIP commands executed at IPL time.
- The abend reason code was one that does not require a dump to determine the cause of abend.
- SDWACOMU or SDWAEAS (part of the system diagnostic work area, SDWA) was used to suppress the dump.
