CICS SLA Alternative view
OMEGAMON XE for CICS on z/OS provides the CICS SLA view, a different view from the Tivoli Enterprise Portal's
Physical view. This alternative view allows you to set workload-performance
thresholds with which you can monitor your CICS transactions to ensure they
comply with your site's service-level agreements (SLAs).
Three new Tivoli Enterprise Portal objects support the SLA feature within OMEGAMON XE for CICS on z/OS:
- service classes
- This object identifies the transactions that share common response-time
goals, grouped together by transaction IDs, user IDs, VTAM terminal ID (that
is, LU names), and CICS region names. A service class is associated with exactly
one workload.
- workloads
- This object groups one or more service classes that you must monitor
as a unit: a workload reflects the status of all the service classes within
it. It is a tool for monitoring multiple related classes and highlighting
the group's worst-performing class in the Service Class Analysis workspace.
- service policies
- This object includes all workloads and all service classes defined for
the enterprise. Service-class goals can vary by service policy; that is, with
service policies, you can change a service class's response-time goals as
dictated by your site's varying requirements. For example, you can define
one service policy for prime-shift operation, another for evening operation,
and yet a third for weekend operation.
Your site's CICSplex can have only
one active service policy at any time.
Using the CICS SLA view within Tivoli Enterprise Portal, you can define and activate each
of these objects. Complete these tasks, in this order:
- Opening the CICS SLA view
- Adding or editing a workload
- Adding or editing a service class
- Editing a service class's classification rules
- Adding or editing a service policy and activating a service policy
- Overriding a service class's goal
- Verifying the CICSplex control settings and saving the updated SLA
definitions
- Returning to the Physical view
Other tasks you might need when implementing the OMEGAMON XE for CICS on z/OS SLA support:
When you have defined your site's SLA environment, you can see the resulting
monitoring data in the Service Class Analysis workspace.
Notes:
- Before your Tivoli Enterprise Portal user ID can access the CICS SLA view and begin modeling
your site's SLA requirements, a user ID with administrator authority must
give it that access; see Allowing access to the CICS SLA view.
- If your installation chooses to monitor its service-level compliance using
only z/OS's native, ISPF-based workload manager, the service policies, workloads,
and service classes you create using this view are ignored. OMEGAMON XE for CICS on z/OS instead
uses the service classes and goals defined by the z/OS workload manager. In
this case, the only procedure you need complete to activate CICS SLA monitoring
is Verifying the CICSplex control settings and saving the updated SLA
definitions.
