Switching system availability monitoring (SAM) on for a MAS

Start of change

This example describes how to use the Web User Interface (WUI) to set up system availability monitoring (SAM) for a MAS.

CICSPlex® SM’s system availability monitoring is easy to set up and is extremely useful. When system availability monitoring is activated for a particular CICS® system, CICSPlex SM warns you if the system becomes unavailable, or if any of these conditions occurs: short on storage (SOS); system dumps (SYSDUMP); transaction dump (TRANDUMP); maximum number of tasks (MAXTASK); system busy (STALL).

Start of changeYou activate monitoring of system availability (SAMOPS!!) by telling CICSPlex SM at which hours of the day you expect the CICS system to be available. You do this by specifying the name of a valid time period definition in the CICS system definition detail view Period definition name field .End of change

Start of changeYou activate monitoring of the SOS (!!SAMSOS), SYSDUMP (!!SAMSDM), TRANDUMP (!!SAMTDM), MAXTASK (!!SAMMAX), and STALL (!!SAMSTL) conditions by switching on real-time analysis for the CICS system.End of change

In this example, you’ll see how to tell CICSPlex SM that CICS system CICSPA01, in CICSplex PLXPROD1, should be running problem-free between 09:00 and 17:30 and, if it isn’t, to warn you. You want system availability monitoring to be switched on permanently for CICSPA01, and to take effect immediately. The time period definition PDFSHFTA, which covers the hours from 09:00 to 17:30, has already been created.

  1. Update the CICS system definition.
    1. From the WUI main menu, click Administration views-->System availability monitoring administration views-->CICS system definitions to open the CICS system definition tabular view.
    2. If the current context is not PLXPROD1, specify PLXPROD1 in the Context field and click Refresh.
    3. Select the entry for CICSPA01 and click the Update action button. This opens a CICS system definition detail view.
    4. In the Primary CMAS name field, type in the name of the CMAS to which CICS normally connects. For this task, type CMSSYS1.
    5. In the Period definition name field, type PDFSHFTA .
    6. Scroll down to the Real time analysis status field and select YES from the drop-down menu.

      If you wanted to activate monitoring of system availability only (and did not want the SOS, SYSDUMP, TRANDUMP, MAXTASK, and STALL conditions to be flagged), just specify SAM rather than YES in this field.

    7. Click Yes at the bottom of the screen.

      The CICS system definition tabular view is redisplayed. The change takes effect immediately.

  2. Look at the CICSPlex SM event notifications.

    Now that system availability monitoring is switched on for CICS system CICSPA01, you can check the system’s availability by clicking Real Time Analysis (RTA) Outstanding Events on the General views section of the WUI main menu. If CICSPA01 is not active, or is not problem-free, at a time that falls within the period defined in time-period definition PDFSHFTA, there will be an entry to that effect displayed in the view.

If you decide later to switch system availability monitoring off for CICS system CICSPA01, update the CICS system definition again (as described in step 1), and specify NO in the Real time analysis status field instead of YES.
