Some messages appear frequently and only indicate a problem if they appear with more than the usual frequency. The example in Figure 103 demonstrates the handling of a message for which the number of occurrences exceeds a specified threshold.

MESSAGE JES CHECKPOINT CONTENTION PROBLEM - PLEASE CHECK
Explanation
The following threshold is specified in the ON MESSAGE statement:
APPEARED 006 TIMES IN 0003 MINUTES
This specification causes the rule to be triggered only when the specified message ($HASP263) is issued at least six times within a three minute time span.
The THRESHOLD parameter in the CTOPARM member also limits the number of times that a rule can be triggered in one interval.
If the THRESHOLD parameter of a rule is set to a value different from that set in the THRESHOLD parameter in the CTOPARM member, the value in the rule overrides the value set in CTOPARM.
If no value, or a value of 0, is set in the THRESHOLD parameter of a rule or the THRESHOLD parameter in CTOPARM, Control-O does not limit the number of times that the rule can be triggered.
