Adding, Modifying, or Deleting an Area

When You Might Want to Make This Change

You can add areas to or delete areas from a subschema or make a modification to an existing area. Normally this is done in conjunction with adding or deleting a record or index structure stored in that area or to move records into a new area for performance reasons.

What Components are Affected

The area definition portion of the subschema is affected by such a modification.

Considerations

• If you modify the usage mode so that a mode is no longer allowed, you may have to modify the READY mode of your program to match.
• If you modify the default usage mode, you should check programs using the subschema to see that there is no conflict.
• If you delete an area, make sure that there are no records or indexes mapping to that area still in the subschema.
• If an area is renamed or deleted, all ADS dialogs that use the subschema must be recompiled if they use neither READY ALL nor DBMS autoready.
