Preparing and Maintaining VLS Libraries in CA Ideal

Each CA Ideal PROGRAM, PANEL, REPORT, and DATAVIEW entity consists of one or more VLS library members and an entity-occurrence in the dictionary facility. (MEMBERS consist of a VLS member only, not a dictionary facility entity-occurrence.) CA Ideal requires that the environment (both VLS members and dictionary facility entity-occurrences) be valid and consistent. If a discrepancy is found, CA Ideal issues an internal error indication and terminates the operation.

The VLSUTIL utility manipulates VLS members to regain continuity between the VLS libraries and the dictionary facility. For more information about VLSUTIL, see the CA IPC Implementation Guide.

The CREATE SYSTEM command creates a new system. The resulting system definition fill-in assigns the VLS libraries. The three libraries for applications in that system are the program source library, the program object code library, and the panel library.

Any of the libraries can be shared across systems or in one system. The administrator can use one library for all systems, one library per system, three individual libraries per system, or any other combination.

This chapter describes the procedures to follow before CA Ideal can use a library (also known as a VLS file).
