ADYSETxx (dump suppression)

ADYSETxx controls dump analysis and elimination (DAE) processing, which suppresses dumps that are 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, use 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.
