CMAS Explorer view
In the SM Administration perspective, the CMAS Explorer view shows the CMASs in the CICSPlex®.
The view shows all the CMASs in the CICSPlex. Active systems are
shown with their applid in parentheses after the system name. Inactive
systems are shown without an applid and with their icon grayed out.

When you select a CMAS, the selected CMAS becomes the current CMAS context for any resource views that require a CMAS as a context.
