Creating Dataviews for CA Datacom/DB Native Command Access › Rules for CA Datacom/DB Native Command Access › Cataloging the Dataview

Cataloging the Dataview

A dataview must be cataloged before CA Ideal can use it. After creating an CA Datacom/DB native dataview using Datadictionary, use the CATALOG DATAVIEW command in CA Ideal.

Access the CATALOG prompter by selecting option 2 on the CA Ideal Dataview Menu. For more information about syntax and description of command, see the section Cataloging a Dataview.

TABLE Attributes

The TABLE attribute DBMS‑USED must be CA Datacom/DB.

The attribute ENTY‑HIST‑VER automatically deletes history status entities in the dictionary database. You can set the number stored in this attribute differently for any file in the dictionary database. Datadictionary uses this attribute when new versions of a dictionary entity are copied or modified into production status. After a new entity is copied to production, the previous PROD version is automatically copied to History. Datadictionary consults the file entity in the dictionary database and deletes the oldest history status version if the number of history occurrences is greater than the value specified in the ENTY‑HIST‑VER attribute. The default value for ENTY‑HIST‑VER is three. You can modify it.

The Datadictionary automatic deletion of history status entities deletes these entities from the dictionary without performing corresponding deletes of VLS members. This attribute affects the maintenance of the following CA Ideal entities in VLS libraries: Program, Panel, Report, and Dataview.
