Scenario 1

In this scenario, you wish to assign storage protection and/or CPU protection to address spaces.

Figure 1. Scenario 1: Address Spaces

Scenario 1: Address Spaces, showing address spaces HAMLET1, HAMLET2, and HAMLET3.

Suppose you have the following classification rules:

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

           -------Qualifier---------    -------Class------   Storage
 Action    Type       Name     Start    Service     Report   Critical
  ____  1  TN         HAMLET1    ___    PRODBAT     ______   NO
  ____  1  TN         HAMLET*    ___    PRODBAT     ______   NO

Note: Many of the panels shown in this section are actually composites of the information displayed after scrolling right from the Modify Classification Rules panels.

To assign storage protection to the address space HAMLET1, change the Storage Critical value to field to YES in the classification rule for HAMLET1:

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

           -------Qualifier---------    -------Class------   Storage
 Action    Type       Name     Start    Service     Report   Critical
  ____  1  TN         HAMLET1    ___    PRODBAT     ______   YES
  ____  1  TN         HAMLET*    ___    PRODBAT     ______   NO

To assign storage protection to the address spaces HAMLET2 and HAMLET3 (but not HAMLET1), change the Storage Critical value to field to YES in the wild card rule for HAMLET*:

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

           -------Qualifier---------    -------Class------   Storage
 Action    Type       Name     Start    Service     Report   Critical
  ____  1  TN         HAMLET1    ___    PRODBAT     ______   NO
  ____  1  TN         HAMLET*    ___    PRODBAT     ______   YES

Note that in this instance, HAMLET1 will not be protected, as it will match the HAMLET1 rule first. To protect all of the address spaces, you would have to specify YES in both rules.

The default values (with no CPU protection assigned) in the service class definitions would be:

Service Class Name . . . . . . PRODBAT   (Required)
Description  . . . . . . . . . Production Batch_____________
Workload Name  . . . . . . . . JES       (name or ?)
Base Resource Group  . . . . . ________  (name or ?)
Cpu Critical . . . . . . . . . NO        (YES or NO)

To assign CPU protection to all of these address spaces, change the value in the Cpu Critical field in the service class definition for PRODBAT:

Service Class Name . . . . . . PRODBAT   (Required)
Description  . . . . . . . . . Production Batch_____________
Workload Name  . . . . . . . . JES       (name or ?)
Base Resource Group  . . . . . ________  (name or ?)
Cpu Critical . . . . . . . . . YES       (YES or NO)
