ADYSETxx allows an installation to control dump analysis and elimination
(DAE) processing, which suppresses dumps that it considers unnecessary
because they duplicate previously taken dumps. DAE suppresses ABEND
dumps that would be written to a SYSMDUMP data set (SYSMDUMPs), Transaction
dumps (IEATDUMP), and SVC dumps, when the symptom data of a dump duplicates
the symptom data of a dump of the same dump type previously taken.
DAE uses the ADYSETxx parmlib member to determine the actions DAE
is to perform.
To change the ADYSETxx parmlib member specification, enter the
SET DAE command.
DAE can take the following actions for SYSMDUMP dumps, Transaction
dumps, and SVC dumps in either a single system or in a sysplex:
- Matching, which means that DAE compares each dump occurrence for
a dump type (SVC dump, or SYSMDUMP and Transaction dumps) to dumps
previously recorded in the DAE data set.
- Updating, which means that DAE records either a unique symptom
or an occurrence of a duplicate symptom string in the DAE data set.
- Suppressing, which means that DAE prevents a dump from being taken
if the dump's symptom data duplicates the symptom data of a previous
dump (of the same dump type) recorded in the DAE data set. Dump suppression
must also be permitted through one of the following:
- The SUPPRESS option is specified in the ADYSETxx parmlib member,
and the VRADAE key is contained in the variable recording area of
the SDWA.
- The SUPPRESSALL option is specified in the ADYSETxx parmlib member,
and the VRANODAE key is absent from the variable recording area of
the SDWA.
