WLM definitions for a colocated Tailored Fit Pricing DevTest or New Application Solution

For a colocated Tailored Fit Pricing DevTest or New Application solution, the service level administrator must define tenant resource groups, tenant report classes, and classification rules as part of the WLM service definition.

The tenant resource groups and tenant report classes are comparable to resource groups and report classes. They allow for the metering and optional capping of workloads, along with the ability to map those workloads directly to Tailored Fit Pricing for IBM Z solutions.
  • Tenant resource groups have sysplex scope, with support for up to 32 tenant resource groups across the sysplex. For each tenant resource group, the system programmer defines one or more tenant report classes, which can be used in classification rules to associate work with the tenant resource group.
  • Tenant report classes are similar to standard report classes. You can configure the information that is reported on behalf of tenant resource groups by associating their tenant report classes with address spaces or enclaves using classification rules.

With this new function, the WLM Administrative Application level changes to 32, which is only available with z/OS V2R2 and above when APAR OA52312 is applied. The functionality level of the WLM service definition changes to 32 as soon as a tenant resource group is defined. A WLM service definition with functionality level 32 cannot be extracted, displayed, modified, installed or activated from a z/OS V2R2 or V2R3 system without APAR OA52312 applied. As soon as the functionality level of the WLM service definition changes to LEVEL032, all actions must be taken from a z/OS V2R2 or z/OS V2R3 system with this APAR applied.
