Important: Beginning with z/OS® V1R3, WLM compatibility mode is no longer available. Accordingly, the IEAICSxx member, the IEAIPSxx member are no longer valid. Options in the IEAOPTxx member that were valid only in compatibility mode also are no longer valid. However, there are some parameters in IEAOPTxx that are still valid and still used by SRM in goal mode. For information on compatibility mode, see a previous version of this publication.

See z/OS MVS Planning: Workload Management for more information on WLM goal mode.

To a large degree, an installation's control over the performance of the system is exercised through the system resources manager (SRM).

Section 1: Description of the system resources manager (SRM) discusses the types of control available through SRM, the functions used to implement these controls, and the concepts inherent in the use of SRM parameters. The parameters themselves are described in z/OS MVS Initialization and Tuning Reference.

Section 2: Basic SRM parameter concepts discusses some basic OPT parameters. z/OS MVS Initialization and Tuning Reference provides descriptions of the OPT parameters and syntax rules.

Section 3: Advanced SRM parameter concepts discusses some more advanced topics.

Section 4: Guidelines provides some guidelines for defining installation requirements and preparing an initial OPT.

Section 5: Installation management controls contains information about commands for SRM-related functions.
