DGConnectIdentifier

The DGConnectIdentifier configurable property specifies the connect identifier the broker uses when making connections to a configuration member.

If you are using DGMGRL, then you supply the value when you enter the CREATE CONFIGURATION, ADD DATABASE, or ADD FAR_SYNC command. If you are using Cloud Control, the value is supplied automatically. The connect identifier for a configuration member must:

  • Allow all other members in the configuration to reach it.

  • Allow the member to reach itself.

  • Allow all instances of an Oracle RAC database to be reached.

  • Specify a service that all instances dynamically register with the listeners so that connect-time failover on an Oracle RAC database is possible.

    Caution:

    The service should NOT be one that is defined and managed by Oracle Clusterware.

  • Have failover attributes set to allow the primary database's Redo Transport Services to continue shipping redo data to an Oracle RAC standby database, even if the receiving instance of that standby database has failed.

  • Use the VALIDATE NETWORK CONFIGURATION and VALIDATE DGConnectIdentifier to confirm that the value specified for the DGConnectIdentifier is correctly configured.

The value of this property is specified in the SERVICE attribute of the LOG_ARCHIVE_DEST_n parameter when the broker configures redo transport services on the primary database.

Note:

All instances of a database must be accessible via the service in MOUNT, READ WRITE, and READ ONLY modes. The service should NOT be one that is defined and managed by Oracle Clusterware or created via Server Control Utility (SRVCTL). For most users it will be sufficient to use the db_unique_name service.
