Creating Storage Control File Objects for New Schema Objects
If you define a new table in Siebel Tools (for example, if you add a new extension table), you must add the table object definition to your storage control file in order for the table to be placed in the appropriate table space.
For example, if you create a new extension table called X_EXTENT, you must create a corresponding object definition in the storage control file:
NOTE: If you have different storage control files for your development environment and production environment, then you must add the new table object definition to both storage control files.
