CA-GSS (System Interfaces) Requirements

CA‑GSS has the following installation requirements:

An IBM supported z/OS version.
CA‑GSS must be installed into an APF authorized library. The CA‑GSS routines can be executed from a STEPLIB concatenation or from a LNKLST concatenation.
Due to cross‑memory communication requirements, CA‑GSS makes itself non‑swappable.
Since CA‑GSS services multiple applications and tasks, the CA‑GSS dispatching priority must be greater than or equal to the highest dispatching priority of any task requesting CA‑GSS services.

The following lists the minimum storage requirements for each CA-GSS distribution library and does not necessarily represent the actual distribution library allocation that is provided during the installation. Data set allocation JCL and (MSM) XML contains a block size of 0 for FB data sets with a LRECL of 80. This change was made in order to follow both IBM’s SMP/E packaging standards, and CA’s packaging standards. Specifying BLKSIZE=0 will allow your system to choose the most efficient block size for these data sets.
