Adding or editing a service class

A service class identifies a block of related transactions that share common response-time goals for a single workload; the transactions must be related by transaction name, the user ID that invoked them, the VTAM terminal ID (LU name) that submitted them, the CICS region running them, or any combination thereof. Defining new service classes, associating them with a workload, and setting their response-time goals usually compose the second step when implementing the SLA support within OMEGAMON XE for CICS on z/OS. To define a new service class:

  1. Within the Service Classes window, press the Create button.

    The Define new Service Class pop-up window opens:

    This graphic shows the Define new Service Class pop-up window, which you use to create a new service class.
  2. Within the service-class editor, define a name for your new service class. The name you supply is converted to uppercase.
  3. Pull down the list of available workloads, and select the existing workload you want to associate this service class with.
  4. Within the Response Time pane, specify the response time you expect for the CICS transactions associated with this service class.
  5. Within the Goal pane, select one of these options:
    Average
    Activating the Average radio button means that the average response time for all matching transactions must at least meet the Response Time specified.
    % of Goal
    Activating the % of Goal radio button and specifying a percentage mean that the given percentage of matching transactions must at least meet the Response Time specified.
  6. Press the OK button.

OMEGAMON XE for CICS on z/OS provides 31 default service classes (ATRANS through ZTRANS, CSM1, CSM2, CSM3, CSM5, and CSMI). Service classes ATRANS through ZTRANS cover transactions based on the first character of the transaction name. Service classes CSM1, CSM2, CSM3, CSM5, and CSMI cover the transactions with those names.

You can also change an existing service class's associated workload or its response-time settings:

  1. Within the Service Classes window, select the service class you want to edit, and press the Edit button.

    The Edit Service Class—Base Goal pop-up window reopens, showing the name of the selected service class, the workload it is currently associated with, and its Response Time and Goal settings:

    This graphic shows the Edit Service Class—Base Goal pop-up window, which you use to edit an existing service class.
  2. Here you can redefine this subset of the service class's current parameters:
  3. When you have correctly redefined the service class, press the OK button.

After you have created a service class, you must identify the CICS transactions, userIDs, LU names, and CICS regions associated with it; continue with Editing a service class's classification rules.
