Scenario 5

This scenario is similar to Scenario 2, but here you'll see what happens when WLM is not allowed to manage one of the regions to the transactions' goals, and how this will prevent protection of a transaction. In this case, assume that it is transaction BB that you wish to give both storage and CPU protection, and assume that at the same time you have exempted region CICSREGT from management to the transaction response time goals.

You've assigned the storage protection to transaction BB using the CICS® classification rule:

Subsystem Type . : CICS         Fold qualifier names?   Y  (Y or N)
Description  . . . IBM-defined subsystem type

           -------Qualifier---------    -------Class------   Storage
 Action    Type       Name     Start    Service     Report   Critical
  ____  1  TN         AA1        ___    TRXAA       AA1RPT   NO
  ____  1  TN         AA2        ___    TRXAA       AA2RPT   NO
  ____  1  TN         BB         ___    TRXBB       ______   YES
  ____  1  TN         CC         ___    TRXCC       ______   NO

You have also assigned CPU protection to the transaction service class TRXBB in the service class definition:

Service Class Name . . . . . . TRXBB     (Required)
Description  . . . . . . . . . CICS Transactions_______________
Workload Name  . . . . . . . . CICS      (name or ?)
Base Resource Group  . . . . . ________  (name or ?)
Cpu Critical . . . . . . . . . YES       (YES or NO)

In the classification rule for CICSREGT, you have exempted the region from management to the transaction response time goals:

Subsystem Type . : STC          Fold qualifier names?   Y  (Y or N)
Description  . . . IBM-defined subsystem type

           -------Qualifier---------    -------Class------   Storage   Manage Region
 Action    Type       Name     Start    Service     Report   Critical  Using Goals Of:
  ____  1  TN         CICSREGP   ___    PRODRGNS    ______   YES       TRANSACTION
  ____  1  TN         CICSREGT   ___    TESTRGNS    ______   YES       REGION

As illustrated in Figure 1, transaction BB runs in both regions, CICSREGP and CICSREGT. Since WLM will not manage region CICSREGT to transaction response times, it will not inherit storage or CPU protection from the TRXBB transaction service class. Transaction BB will therefore not run with storage or CPU protection in region CICSREGT.
