Based on user specifications, Record Analysis and Processing accepts and inspects the SMF and EXPORT records. Only the most current version of a catalog record is actually processed, although older records are also analyzed. If the only record for a catalog entry is the one from the EXPORT input, that record is written to the new "EXPORT data set". If the most current SMF record is an insert or an update, it is written to the "EXPORT data set" (if necessary, after a common VSAM password is inserted to replace VSAM security fields blanked out in the SMF record). If the most current record is a deletion, that record is omitted from the new "EXPORT data set". As each record is processed, it is tallied in an appropriate category. Finally, reports of errors, anomalies, correct processing and a report of records by data set are produced to aid in error resolution and, if desired, in auditing the process.

In summary, CRURRAP needs start and stop dates and times and a multi-system clock difference as execution parameters. The sorted SMF catalog records covering the start/stop interval and an EXPORT copy of the catalog from the start date and time are supplied as input. A new "EXPORT" data set is produced as output.

Note: It is also possible to use programs other than IDCAMS EXPORT for regular backups, but additional recovery steps will be required. See Alternate Backup Methods.
