How the Main Services Address Space Is Initialized

Before you start the main services address space, review how the initialization information is obtained.

Initialization performs the following actions:

The primary initialization information is obtained from the System Configuration Options member in the system parameter library SYS1.PARMLIB.
The System Configuration Options member contains the following information:
- SVC number
- Run-time library names
- Enabled features
A System Configuration Options member is defined for each z/OS system.

To run multiple copies of CA SYSVIEW on a single system, review these rules:

Multiple copies of the same release must specify different subsystem IDs.
Multiple copies of different releases can use the same subsystem ID.
When multiple copies of different releases are desired, use the SVC from the highest release and is compatible with the previous releases.
