The system resources manager

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.
