Default Rule

If necessary, define Control-M/Tape rule that implement Tape Default Retention policies (DEF statements) specified in the CA-TLMS System Options (TLMSIPO) member. This ensures compatibility between Control-M/Tape and CA-TLMS operations. For example, define rule to handle datasets that are managed in CA-TLMS with Keep Date retention type (Type 2).

The conversion process converts the TLMS RMF Default record into a Control-M/Tape rule named $DEFAULT. This enables Control-M/Tape to use the same default retention period that was used by TLMS. If there is no $DEFAULT rule, Control-M/Tape uses the retention period set in the DEFEXPDT parameter in the CTTPARM member that was created when Control-M/Tape was installed. Compare the retention period specified in the $DEFAULT rule with that in the DEFEXPDT parameter, and consider whether to delete the $DEFAULT rule and allow the setting in the DEFEXPDT parameter to take effect.

For more information on the DEFEXPDT parameter, see the Control-M/Tape installation parameters section in the INCONTROL for z/OS Installation Guide.
