Understanding Tape Retention › Retention Hierarchy

Retention Hierarchy

If retention is defined in more than one place, CA TLMS uses this hierarchy to determine which definition to use:

• Specific Retention Master File entries
• A unique CA TLMS keyword value coded on the JCL EXPDT parameter
• The Retention Master File default entry

For example, if a data set has an EXPDT keyword value, that value will override the RMF entry created by the default retention control statement. However, the EXPDT keyword value will, in turn, be overridden by an RMF entry created by a retention control statement that has been coded to cover this specific data set.

Note: This is true only if it is a specific keyword, and does not necessarily apply to an IBM EXPDT or RETPD coded in the JCL. Examples of keywords are EXPDT=98ddd, 99000 and 99ccc.
