During Standard auditing, once a record has been selected by the sweep process, CA IDMS/DB Audit can perform set walk processing. The main function of set walk processing is to ensure the integrity of a set occurrence. If the record retrieved by CA IDMS/DB Audit is the owner of one or more set occurrences, CA IDMS/DB Audit walks the set from the owner record until it reaches the end-of-set.
If CA IDMS/DB Audit encounters any physical integrity errors during set walking, it returns to the owner record and walks the set again, creating an extract record for each record found in the set. The file of extract records is saved for later use by the FIX phase or the REPORTS phase.
The two options used to initiate set walking are USERSETS and CALCSETS. The SETLIMIT and DBKEYTBL options provide additional controls on set walking.
