This information supports z/OS® (5650-ZOS).

Purpose of this information:

This information provides reference information about JES3 initialization statements used to initialize, manage, and tune JES3.

Who should use this information:

JES3 system programmers or anyone who is responsible for initializing or tuning JES3 should use this document.

How to use this information:

This information describes initialization statements and parameters that you can use to configure your JES3 complex. These statements and parameters enable you to define to JES3 your installation's job management policies and the resources that JES3 can use.

Initialization statements appear in alphabetic order. This arrangement allows you to quickly find a statement description without going to the index.

Many statement parameters influence or change the values of other initialization parameters. For example, a particular parameter coded on one statement may override a parameter coded on another statement. Table 2 and Table 3, in Initialization Statement Reference Summary, identify interrelated statements and parameters. This table also lists the default values for parameters that you omit from your initialization stream.

If you specify an invalid subparameter on certain JES3 initialization statements, JES3 substitutes the subparameters default value and continues to run. To find out which initialization statements and subparameters select defaults, see Table 1.
