Providing WLM definitions manually

Edit online

WLM manually provides information about the WLM definition parameters. These definitions describe the separation and affinity requirements for a set of dynamic transactions.

About this task

If you want to manually define the required WLM definitions rather than have the Data Virtualization Manager server automatically install them at startup time, take the following steps:

Procedure

  1. Start the WLM administration tool. The IBM TSO/ISPF WLM administration tool is used in the following examples. Other administrative tools can also be used.
    1. Enter WLM from the ISPF/PDF option 6 panel to log on to the IBM TSO/ISPF WLM administration tool.
    2. Select Option 2 Extract Definition from WLM Couple Data Set from the Choose Service Definition box.
  2. Define the workloads.
    1. Select Option 2 Workloads. Press Enter.
      WLM displays the Workload Selection List panel.
    2. Create workload AVZ_WKLD.
  3. Define the service classes.
    1. Select Option 4 Service Classes. Press Enter.
      WLM displays the Service Class Selection List panel.
    2. Here you create the following service classes:

      • AVZ_SCHI ZIIPCLASS=AVZ IBM Data Virtualization Manager for z/OS high priority

      • AVZ_SCNM ZIIPCLASS=AVZ IBM Data Virtualization Manager for z/OS normal work

      • AVZ_SCTX ZIIPCLASS=AVZ IBM Data Virtualization Manager for z/OS client work

      Note:

      • Do not change service class names.

      • ZIIPCLASS=AVZ is a required keyword in the description.

      • The values that are shown for service class goals are default values that you can modify.

  4. Define subsystem type AVZ and its classification rules.
    1. Select Option 6 Classification Rules. Press Enter.
      WLM displays the Subsystem Type Selection List for Rules panel.
    2. Define subsystem type AVZ and associated classification rules.
  5. Define the report classes.
    1. Select Option 7 Report Classes. Press Enter.
      WLM displays the Report Class Selection List panel.
    2. In this panel, create the following report classes:

      • AVZ_RCP1 Dnnnn Pnnn PERIOD 1

      • AVZ_RCP2 Dnnnn Pnnn PERIOD 2

      • AVZ_RCP3 P100 PERIOD 3

      Note:

      • Do not change report class names.

      • The terms in the report class descriptions are used to provide CPU offload criteria for Data Virtualization Manager server work as follows:

        Dnnnn: The number of service units during which the dispatchable units are in the associated period while eligible for offloading to the zIIP processor.

        Pnnn: The percentage of time in the associated period that Data Virtualization Manager server tries to offload work to the zIIP processor.

  6. Activate a Service Policy.
    1. Select Option 3 Activate Service Policy from the Utilities drop-down menu on the panel.
    2. Follow directions to activate a policy.
