Data set naming conventions
In most cases, the use of z/OS® catalog facilities for image copy and change accumulation data sets is optional because DBRC always records volume serial information pertaining to these data sets in the RECON data set. If you catalog image copy and change accumulation data sets, they must have unique data set names.
DBRC provides a data set naming convention to help you generate unique data set names for those image copy data sets (for HSSP image copies and concurrent image copies, as well as standard image copies) and change accumulation data sets that you define for future use.
If you use this convention all the time, uniqueness of your data set names is assured. If you use the convention only occasionally, you are sent a message at the end of your job step that indicates that you did not follow the naming convention and that duplicate data set names could exist in the RECON data set. DBRC assumes that data set names specified in quotation marks do not follow the naming convention. Therefore, DBRC does not check data set names surrounded by quotation marks.
When you add records to the RECON data set that create data sets
for one of the recovery utilities to use in the future and you are
using this data set naming convention, you can specify either the
fully-qualified data set name or simply the abbreviation high-level-qualifier.*.low-level-qualifier (for
example, ALPHA1.*.OMEGA). You can use these abbreviated names on any INIT, CHANGE, DELETE,
or NOTIFY.REORG command of DBRC when you are specifying
the name of a data set that follows the naming convention. DBRC expands
the abbreviated name to its fully-qualified form before it accesses
the RECON data set.
