When you want only to verify the accuracy of your aggregate recovery without actually recovering the data sets, issue the ARECOVER command with the VERIFY parameter. This optional test run allows aggregate recovery to determine if any errors or data set naming conflicts exist. In the event of unresolved data set naming conflicts, aggregate recovery fails and a conflict resolution data set is created to help you resolve the conflicts. Remember, no data sets are recovered.
When performing verification processing, aggregate recovery calls installation exits ARCSKEXT and ARCCREXT, if requested and successfully loaded. ARCSKEXT allows you to specify if a data set should be skipped so that it is not included in the aggregate recovery. ARCCREXT allows you to specify how a data set naming conflict should be resolved.
If the data set naming conflicts are not resolved, the verification fails and a conflict resolution data set is created.
When processing completes, make sure that the ARECOVER command completed successfully with a return code of zero.
