CA Global SubSystem

Note: The topics in this section assume that you are familiar with REXX programming.

Overview

The CA Global SubSystem, CA‑GSS, lets CA Technologies products communicate with one another using cross memory communications and access authorized operating system services. CA‑GSS gives you quick access to information from different areas to determine how to use your system resources more efficiently.

Many CA Technologies products use CA‑GSS services during their normal operation. For example, CA‑GSS lets CA Jobtrac Job Management access data that CA SYSVIEW Performance Management gathers, and then use this information to determine how to schedule a particular job.

The CA‑GSS services provide connectivity by using a collection of one or more REXX subroutines that are edited, compiled, and executed as a single program. This collection of subroutines is named an IMOD.

IMODs can monitor, automate, and regulate system activities. CA Technologies products use IMODs to communicate among themselves, and to provide extra product functionality. You can use IMODs for, but not limited to, the following types of tasks:
