Controlling CMEM Rule Operation Mode

The mode of operation (the trace mode) for a CMEM rule is determined by parameter MODE in its rule definition. Sometimes it is useful to override the operation mode of all active rules and verify that events and actions are recorded in a particular way. For example

• Ensure a trace of all rules (that is, all events and actions are recorded) to facilitate analysis of the interaction between rules.
• Record (trace) only the triggering of every rule.

Global trace operations are requested using operator commands, as follows:

Activate a complete trace by issuing the following command:

F CTMCMEM,LOG=ALL

All rules are fully traced as if they were defined with mode LOG. This operator command must only be used temporarily for specific tests, because extended use of LOG mode can adversely affect CMEM performance.

Trace rule triggering only by issuing the following command:

F CTMCMEM,LOG=TRIGGER

Only rule triggering is traced for all rules. However, rules defined with mode LOG are fully traced.

Restore the default operation mode (as defined in the rule definition) for each rule by issuing the following command:

F CTMCMEM,LOG=DEFAULT
