In this example, you’ll see how to get CICSPlex® SM to monitor the LU 6.2 connections in CICS® system CICSPT02, which has recently been experiencing LU 6.2 problems. Both an external message and an event notification are to be issued whenever any connection is found to be in RELEASED status. The monitoring will not be limited to specific hours of the day, but will be continuous.
The task is fundamentally the same as the one shown in the example Monitoring resources permanently. The interesting differences arise in the creation of the evaluation definition, the action definition, and the analysis definition. Those steps are shown here:
From the current view, issue the EVALDEF command. From the EVALDEF view, issue the CRE command. Complete the first Create Evaluation Definition panel as shown here:
------------------- Create Evaluation Definition for PLXPROD1------------------ COMMAND ===> Name ===> RTEPAY03 Description ===> Connections in CICSPT02 Sample Interval ===> 30 Interval between samples in seconds TableName ===> CONNECT Resource Table Name or * Instance Pattern ===> * Specific or generic pattern Result Set Action ===> ANY Operation(ALL,ANY,SUM,MIN,MAX,AVG,CNT) Separate Task ===> NO Run as a separate task (YES, NO) Evaluation Column ===> CONNSTATUS Column name to evaluate or * either Operator ===> EQ (EQ,NE,LT,GT,LE,GE) Value ===> RELEASED Severity ===> VHS (VLS,LS,LW,HW,HS,VHS) or set Thresholds: Provide 3 low and/or 3 high values, N=Normal VLS LS LW (N) HW HS VHS View ===> CONNECT View invoked for this Evaluation Type DOWN or UP to view other Evaluation Definition screens. Press Enter to create Evaluation Definition. Type END or CANCEL to cancel without creating.
In this example:
Issue the DOWN command and complete the second Create Evaluation Definition panel as shown here:
------------------- Create Evaluation Definition for EYUPLX01------------------ COMMAND ===> Name ===> EYURTE01 Filter string expression: (Type FILTER to list columns) ===> TYPE=LU62. ===> ===> ===> ===> ===> ===> ===> ===> ===> Modification string expression: (Type MODIFY to list modifiable columns) ===> ===> ===> ===> Type DOWN or UP to view other Evaluation Definition screens. Press Enter to create Evaluation Definition. Type END or CANCEL to cancel without creating.
In this example, the filter string limits the checking to LU 6.2 connections.
From the current view, issue the command ACTNDEF. From the ACTNDEF view, issue the command CRE. Complete the Create Action Definition panel as shown here, and press Enter:
-------------------- Create Action Definition for PLXPROD1 -------------------- COMMAND ===> Action Name ===> RTAPAY03 Description ===> Connections lost in CICSPT02 Event ===> YES Generate Event (Yes/No) Event View ===> CONNECT View for Event Priority ===> 255 Event Priority (1 to 255) Event Text ===> Connections lost in CICSPT02 External Msg ===> YES Generate External Message (Yes/No) Enter Msg ===> Connections lost in CICSPT02 Exit Msg ===> CICSPT02 connections now OK Alert ===> NO Generate Alert (Yes/No) CMAS Name ===> CMAS to Issue Alert Enter Text ===> Exit Text ===> Restart ===> NO Cancel for ARM Restart (Yes/No) Press Enter to create the Action Definition. Type END or CANCEL to cancel without creating.
This action definition tells CICSPlex SM that you want both an event notification and an external message to be issued.
Issue the command RTADEF from the current view. From the RTADEF view, issue the command CRE. Complete the Create Analysis Definition panel as shown here, and press Enter:
------------------------ Create Analysis Definition for PLXPROD1 -------------- COMMAND ==> Name ===> RTDPAY03 Description ===> Connections in CICSPT02 Perform Ops ===> NO Perform EVALDEF operations changes (YES, NO) Sample Interval ===> 30 Interval between samples in seconds (1-86400) Action Name ===> RTAPAY03 Action definition name or generic VLS LS LW HW HS VHS Entry Intervals ===> 0001 0001 0001 0001 0001 0001 Exit Intervals ===> 0001 0001 0001 0001 0001 0001 Evaluation expression: ===> RTEPAY03 ===> ===> ===> ===> ===> ===> Press Enter to create the Analysis Definition. Type END or CANCEL to cancel without creating.
(You can allow the Entry Intervals and the Exit Intervals to default to 0001.) CICSPlex SM will evaluate the results of the evaluation definition (defined in RTEPAY03) every 30 seconds.
You would install the analysis definition in the CICS system CICSPT02 by specifying CICSPT02 as the scope of the analysis specification.
