Restricting Subschema Names

Determines Valid Subschemas

You can request that the subschema name bound by an application be present in the database name table in order for the application to execute using the subschema. You can use this feature to prevent access to the database from an unauthorized subschema.

To request this feature, specify MATCH ON SUBSCHEMA REQUIRED on the DBNAME statement.

Note: You can also achieve the same or better protection using rununit security documented in CA IDMS Security Administration Guide.
