Data definition control support database
The data definition control support (DDCS) database refers to a user-maintained collection of tables that are used by data definition control support to restrict the submission of specific Db2 DDL (data definition language) statements to selected application identifiers (plans or collections of packages).
This database is automatically created during installation. After this database is created, you must populate the tables to use this facility. The system name for this database is DSNRGFDB.
