Components

CA‑GSS provides a simplified communication interface that lets various CA products communicate easily, seamlessly, and reliably. The following components make such communication possible:

• GOAL (the CA‑GSS anchor)—Provides a single identification point for all other CA‑GSS components, and all CA products that use the CA‑GSS services.
• CA‑GSS Base Product—Provides authorized services for CA products to reduce the dependence on CA‑supplied SVC routines. This includes communication between address spaces on a single z/OS system.

  It comprises a set of service routines and data areas in the extended common services area (ECSA), and an active address space owning a system linkage index (LX).

• IMODs—Are compiled REXX‑based routines executed by ISERVE. CA supplies many IMODs to perform numerous integral services. You can also create IMODs to interface with CA products or to provide locally maintained functions.
• ISERVE (IMOD services routine)—Enables execution of IMODs. A primary ISERVE runs in the CA‑GSS address space. You can use secondary ISERVEs for isolation, chargeback, or testing purposes. ISERVE is also available as a single‑user utility program (SRVBATCH) for the batch execution of IMODs.
• IMOD Editor—Is an ISPF‑based editor program that enables easy creation and maintenance of IMODs. Included in the editor is an IMOD test facility.
• GoalNet—Links multiple ISERVEs on multiple systems into a single integrated environment.
