The example in Figure 112 demonstrates how a rule can issue a command and analyze the results of the command request.

Explanation
This rule checks the status of a specified job (CICSTEST) every ten minutes. If the job is not active, a message is sent to notify the operator of the problem. The rule works as follows:
ON EVENT...
Since ON EVENT is specified for the rule, the rule is triggered immediately when runtime criteria are met. The specified runtime criteria, a value of 010 specified for the INTERVAL parameter, indicates that the rule is triggered every ten minutes.
DO SET=%%MYSTC = CICSTEST
DO SET=%%JSTAT = INACTIVE
Two local variables are set using the above statements at the beginning of this rule:
DO COMMAND=D A,%%MYSTC
The rule issues this command to obtain information on the job specified in the %%MYSTC variable (CICSTEST). If the name of the job is contained in the response to the command, it indicates that the specified job is active.
IF %%$W2 %%$M* EQ %%MYSTC
DO SET=%%JSTAT = ACTIVE
This IF statement checks if the second word (%%$W2) in the current command response line (%%$M*) is the job name (%%MYSTC). If the second word in the current command response line is the job name (CICSTEST), the %%JSTAT variable is set to ACTIVE. Since the response to this command is usually more than one line, the ENDMSG parameter is specified to ensure that the IF statement is applied to each line of the command response.
IF %%JSTAT NE ACTIVE
DO SHOUT = = TO OPER URGENCY R SYSTEM CTO282I
MESSAGE %%MYSTC IS NOT ACTIVE - CHECK WHY
When the last line of the command response is detected, this IF statement checks if the %%JSTAT user-defined variable now contains the value ACTIVE. If %%JSTAT does not contain the value ACTIVE, this indicates that the job name was not located in the command response and the operator is notified that the job is inactive.
Note: The %%MYSTC variable is used to contain the name of the job to be checked so that the rule can be used to check other jobs by changing only the specification of the job name in the statement at the beginning of the rule (DO SET=%%MYSTC = ).
