Naming Convention

The dialogs assign z/VSE resource names according to some naming convention.

Part of the resource name is the subarea number. This scheme preserves the uniqueness of resource names, even in multi-domain networks.

The naming convention uses a four-digit subarea number. This naming convention accommodates more than 255 subareas. It is a prerequisite for extended subarea addressing, and you are strongly recommended to use this naming convention.

If you migrate your hardware and terminal definitions from an earlier VSE system, you have to stick with the naming convention that you previously used (you cannot change naming conventions during the migration).

If you do not migrate, you can make a selection: after Initial Installation of your z/VSE, the dialog asks you to indicate whether your VTAM® resource names are to follow the old naming convention or the one which carries a four-digit subarea number. Choose the four-digit subarea number option.

Figure 1 shows the 4-digit subarea naming convention.

Figure 1. 4-Digit Subarea Resource Naming Convention
An explanation of this figure is provided in the surrounding text.
Some Special Rules:
  1. The CICS® termID of an autoinstall terminal starts with an 'A'.
  2. Some VTAM books have PU statements that serve as a placeholder and do not correspond to any device you defined. Under the 4-digit subarea naming convention, their names start with 'Z'. An example of such a book is VTMSW1 - the switched line definition.
