The CA Global SubSystem, CA‑GSS, lets CA 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 products use CA‑GSS services during their normal operation. For example, CA‑GSS lets CA Jobtrac Job Management access data gathered by CA SYSVIEW Performance Management, and then use this information to determine how to schedule a particular job.
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 called an IMOD.
IMODs can monitor, automate, and regulate system activities. CA products use IMODs to communicate among themselves, and to provide additional product functionality. You can use IMODs for, but not limited to, the following types of tasks:
