Composite Entities

The most important concept that must be considered when establishing multiple environments is that most CA Ideal entities are not simple library members, but composites of multiple members and Datadictionary entries that must be kept together.

• Program source is a composite of a Datadictionary entry and members for Procedure, Working data, and Parameter data.
• Program object is a composite of multiple members and includes the Datadictionary entry for non-Production programs.
• Panels are composites of a Datadictionary entry and Panel library members.
• Systems are composites of Datadictionary entries and VLS files.
• Members (for example, express signon) are composites of the Datadictionary entries defining the user and the VLS members themselves.
• Program or Panel Load Modules are composites of Datadictionary entries and the (multiple) executable members. If Application Module Tables are used, these can take the place of the dictionary entries.
• Regions that share these entities must therefore share the entire set of storage for them. You must consider a Datadictionary and the VLS files and load modules it describes as a unit for sharing.
• If, for example, a development environment and a production environment do not share the dictionary, they must not share the other files, and the Ideal entities must be transported between them using the appropriate utilities to ensure that all components are present and matched.
