Setting performance objectives for distributed workloads by using z/OS® Workload Manager

You can use z/OS Workload Manager (WLM) support, to establish z/OS performance objectives for individual DDF server threads.

About this task

z/OS supports enclave system request blocks (SRBs). A z/OS enclave lets each thread have its own performance objective.

The z/OS performance objective of the DDF address space (ssnmDIST) does not govern the performance objective of the user thread.

Procedure

Assign the DDF address space (ssnmDIST) to a z/OS performance objective that is similar to the Db2 database services address space (ssnmDBM1).

The z/OS performance objective of the DDF address space (ssnmDIST) determines how quickly Db2 is able to perform operations associated with managing the distributed Db2 workload, such as adding new users or removing users that have terminated their connections. This performance objective should be a service class with a single velocity goal. This performance objective is assigned by modifying the WLM Classification Rules for started tasks (STC).
