Rule Search

The purpose of the rule search is to fill in (locate actions for) all Action categories. (Action categories are described under "Loading and Accessing Rules in Memory" on the preceding pages.) For example, Control-M/Tape tries to determine, based on rule specifications, how stacking, pool allocation, retention, vaulting, and so on are performed.

Control-M/Tape may have to search several rules until all Action categories are located. The search continues until all Action categories are located, or until a matching rule is found that specifies the expression CONTINUE SEARCH=N (No).

Action categories that are not filled in by a specific rule for a given data set can be filled in by more generic rules.

To understand how the rule search works, examine the examples below:
