Specifies a unique name for the database at this destination.
|Valid values||The name must match the value that was defined for this database with the DB_UNIQUE_NAME parameter.|
|Requires attributes ...||None|
|Conflicts with attributes ...||None|
|Corresponds to ...||DB_UNIQUE_NAME column of the V$ARCHIVE_DEST view|
This attribute is optional if:
This attributes is required if the LOG_ARCHIVE_CONFIG=DG_CONFIG initialization parameter is specified and if this is a remote destination (specified with theSERVICE attribute).
Use the DB_UNIQUE_NAME attribute to clearly identify the relationship between a primary and standby databases. This attribute is particularly helpful if there are multiple standby databases in the Data Guard configuration.
The name specified by the DB_UNIQUE_NAME must match one of the DB_UNIQUE_NAME values in the DG_CONFIG list. Redo transport services validate that theDB_UNIQUE_NAME attribute of the database at the specified destination matches the DB_UNIQUE_NAME attribute or the connection to that destination is refused.
The name specified by the DB_UNIQUE_NAME attribute must match the name specified by the DB_UNIQUE_NAME initialization parameter of the database identified by the destination.
This 10g new parameter must be set differently for a standby from that of the primary even though their db_name's are the same.
