You can terminate a Data Guard association by terminating the DB system with the standby database.

You must terminate the DB system with the standby database before terminating the DB system with the primary database. Terminating the DB system with the standby database automatically terminates the Data Guard association. If you try terminating a DB system that has the primary before terminating the standby, the terminate operation will not complete.

Alternatively, you can switch over the primary database to the standby role, and then terminate it.

For more instructions on terminating a DB system, see Terminate a DB System.
