The example in Figure 113 shows how a KOA script is run in a Special server and used to check whether or not CICS is responding.

Explanation
If it is important to you to know if CICS is responding at your site, a rule such as this one can help you track CICS response. This EVENT rule is triggered every two minutes (specified by the value set in the INTERVAL parameter) between the hours of 7 a.m. and 6 p.m. (specified by the FROM and TO parameters).
A KOA script is used to check whether or not CICS is responding:
DO KSL=CICSKOA
This statement activates the specified KOA script (CICSKOA).
INITPROC CICP1
The INITPROC subparameter is used to specify a Special server where the KOA script should be run. Use of a Special server can reduce possible delays in script execution.
For more information about Control-O servers, see Chapter 5, "Control-O Servers,".
An IF statement checks the %%$KSLRC System variable, which contains the return code of the KOA script.
If the return code is not 0 (meaning that the script did not end OK), the operator is informed by a SHOUT message.
