The RDS is used to supply expiration criteria after a tape data set has been created. The batch program TMSEXPDT and the Real-time Expiration option process the RDS and compare the control statements that it contains with the TMC records. For the RDS to override the expiration date, a status indicator in the TMC record must indicate that the data set is eligible to be overridden. This indicator is always turned on when there is no JCL-supplied EXPDT, RETPD or ACCODE parameter.
CA 1 system option RO provides the means to turn this indicator on even when the JCL supplies the retention, giving the RDS the final authority on all tape data set retention. When the option is on, it facilitates centralized enforcement of retention standards. A RDS option of SELECT=ALL allows all TMC records meeting selection criteria to be assigned a new expiration date regardless of the status indicator in the TMC.
The SELECT=ALL RDS option can only be used with the batch program TMSEXPDT. This option is not supported by the Real-time Expiration option.
