The entries on the DSNTIPZ panel allow you to install and tailor data
definition control support.
Two SQL tables (application registration and object registration) are identified and created even
if data definition control support is not installed. This simplifies future activation of the
facility. Specified application identifiers (Db2 plans or collections of packages) can be
registered in the application registration table, and, optionally, their associated Db2 object names can be registered in the object
registration table. Db2 consults these two
tables prior to accepting a given DDL statement to make sure that a particular application
identifier and object name are registered.
