For DDL to be replicated as desired, the pdb_setrepddl command must be used to set filtering rules accordingly. Also, you must set the ddl_username and the ddl_password. See the Replication Agent Reference Manual for details on using the pdb_setrepddl command.
DDL replication is not available for UDB.
To replicate DDL:
Replication Agent requires a unique user name to be supplied that has authority to execute all DDL commands at the standby database.
Replication Server must have a database-level replication definition with replicate DDL set in the definition.
For details about configuration property ddl_username and for database-level replication definition, refer to the Replication Agent Reference Manual.
