DAE_SUPPRESSING

Description:

Checks that DAE is active and has the configuration recommended by IBM®.

Reason for check:

The system requests dumps that you may not need. Dump Analysis and Elimination (DAE) is designed to suppress duplicate dumps and to help prevent the system from using unneeded resources by capturing diagnostic data repeatedly for the same problems. This check will detect whether DAE is active and your settings match those recommended by IBM.

z/OS® releases the check applies to:

z/OS V1R11 and later.

Parameters accepted:

The following parameters are supported to identify the expected suppression options.

SVCDUMP(SUPPRESSALL | SUPPRESS | NONE)

Specifies that the check compare the current SVCDUMP suppression option (specified in the SVCDUMP statement of the ADYSETxx parmlib member) to the specified value and write exception message ADYH004E upon mismatch.

Default: SUPPRESSALL

SYSMDUMP(SUPPRESSALL | SUPPRESS | NONE | ANY)

Any choice other than ANY indicates that the check should compare the current SYSMDUMP suppression option (specified in the SYSMDUMP statement of the ADYSETxx parmlib member) to the specified value and write exception message ADYH005E upon mismatch.

ANY indicates that any option is acceptable so that there is never a mismatch.

Default: ANY
