Re: db_unique_name

I am assuming you are talking about Data Guard configuration.


It depends upon the type of the standby database (physical/logical).


In a case of a physical standby database DB_NAME must be the same for all
databases participating in the configuration. On other hand DB_UNIQUE_NAME
specifies a globally unique name for the database which is used to uniquely
identify a database in the standby configuration. Therefore only one
database, usually the primary one, will have same value for both parameters.

In a case of a logical standby database, DB_NAME for the standby database
may be different than the primary one hence both DB_UNIQUE_NAME and DB_NAME
parameters could be set to the same value.
