Software Changes

Changes are required to set up subsystem IDs, load libraries, and VTAM:

Two subsystem IDs are required for the initialization of the required subsystems. The IDs have the following default values:
- SOLV for the SOLVE Subsystem Interface (SSI), which enables a region to communicate with other software on the system
- Domain ID of the region for the region interface that enables a region to issue operating system commands and receive messages
The SOLVE SSI started task and the region automatically identify these IDs to the system. If you want to set the IDs permanently, you can set them in the SYS1.PARMLIB(IEFSSNxx) member. Add the ID for the region interface first (after the job entry subsystem (JES)) in the list of subsystem names.
The following load libraries for CA NetMaster NM for TCP/IP must be APF-authorized:
- CC2DLOAD
- CC22DPLD (if SSL is installed)
A VTAM major node member, which contains application definition statements for all ACBs required by your product region, must be created and added to SYS1.VTAMLST. You can use the Create VTAM Definitions and Table option of the product's Install Utility to perform this task.

Note: For more information, see the Installation Guide.
