Product Subsystems

CA SYSVIEW no longer requires you to define an MVS subsystem entry as in releases of CA SYSVIEW before Release 13.5. Nor does it use or dynamically create an MVS subsystem entry.

A SYSVIEW subsystem ID now associates with each instance or installation of CA SYSVIEW. The subsystem ID is used to define or determine the system configuration parameters.

Use the following guidelines:

• Use a four-character SYSVIEW subsystem ID that associates with each instance or installation of CA SYSVIEW. This subsystem ID defines or determines the system configuration parameters.

  Default SYSVIEW subsystem ID: GSVX

  Note: We recommend using the default of GSVX unless you use multiple instances of CA SYSVIEW on the same system.

• Specify the SYSVIEW subsystem ID as a parameter on each invocation of CA SYSVIEW. You can specify the parameter differently depending on the type of invocation.
• Use the user replaceable module, GSVBSSID, only when the subsystem ID is not provided as a parameter on the invocation of SYSVIEW. GSVBSSID contains the default SYSVIEW subsystem name.

Server Address Spaces

GSVXMAIN program alias has been removed.

In previous releases, the program you executed for the server address spaces was specified as GSVXMAIN. GSVXMAIN was an alias to the program GSVXASCT. The alias GSVXMAIN is no longer defined.

The following SYSVIEW started task procedure specifies GSVXASCT as the program to execute:

SYSVIEW - Main Services Address Space
SYSVUSER - User Interface Address Space
SYSVAUX - Auxiliary Services Address Space
SYSVIEW EXEC PGM=GSVXASCT
