Primary CA-GSS Memory

The CA‑GSS primary subsystem requires the following storage. All storage estimates are for the base configuration and reflect only storage that CA‑GSS uses explicitly. Storage that other CA Technologies products, the operating system, VTAM, and other entities use is not included.

• 3 MB (minimum) private storage. Except for I/O buffers and interfaces to some external routines, this storage resides above the 16-MB line.
• 160 bytes of CSA for a subsystem anchor and related storage.
• 120 KB of ECSA. This storage is used for buffers, communication, and PC routines. This storage is released, recovered, or reused upon CA‑GSS termination or restart.
