ORA-16795

Error: ORA-16795: Database resource guard detects that database reinstantiation is required

Causa: In the act of failover or switchover, the database resource guard may detect that reinstantiation of the database is necessary due to the impending role change. This occurs when the database resource guard recognizes a situation in which the database in question cannot be a viable standby database for the new primary database.

Acción: Reinstantiate the database on the site indicated by the broker and then re-add that site to your broker configuration.
