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:
- Within the Service Classes window, press the Create button.
The Define new Service Class pop-up window opens:
Figure 9. The Define new Service Class window for adding a new service class
- Within the service-class editor, define a name for your new service class.
The name you supply is converted to uppercase.
- Pull down the list of available workloads, and select the existing workload
you want to associate this service class with.
- Within the Response Time pane, specify the response time you expect for
the CICS transactions associated with this service class.
- 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.
- 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:
- 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:
Figure 10. The Edit Service Class—Base Goal window for updating an existing service class
- Here you can redefine this subset of the service class's current parameters:
- The workload it is associated with
- Its response-time goal: either increasing or decreasing it
- The type of goal for this service class, either average or percentage,
as well as the percentage itself
- 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.
