Welcome
IBM Z Workload Scheduler
Welcome to the IBM Z Workload Scheduler documentation, where you can find information about how to install, maintain, and use the product. The documentation has been updated for version 10.2 SPE (Revised April 2025).
Customization and Tuning
Customizing IBM Z Workload Scheduler
Implementing security
This chapter explains how you use IBM Z Workload Scheduler security features to protect IBM Z Workload Scheduler functions and data.
Examples of security strategies
A centralized security strategy
All IBM Z Workload Scheduler users are gathered in one area. They have at least a working knowledge of all the major functions of IBM Z Workload Scheduler. Because they share the same tasks, there is little need to divide authority.

      - Controlling access to IBM Z Workload Scheduler
      - Functions and data that you can protect
        You can use fixed resources and subresources to protect IBM Z Workload Scheduler functions and data.
      - Access requirements to fixed resources for dialog users
        To use an IBM Z Workload Scheduler dialog, you need the authority to access the required resources.

        External access to IBM Z Workload Scheduler
        Access through the IBM Z Workload Scheduler subsystem
        A decentralized security strategy
        Most IBM Z Workload Scheduler work is delegated to representatives of the user departments. They perform all IBM Z Workload Scheduler functions (including reruns and JCL corrections during the day) but only for the applications in their own department.

External access to IBM Z Workload Scheduler

Update access to the IBM Z Workload Scheduler data sets is given to OPCSPEC. This provides access outside IBM Z Workload Scheduler so that the manager and group leaders can submit batch jobs that cause updates, such as daily-plan-extend. The system programmers can use non-IBM Z Workload Scheduler programs to extract diagnostic information.
