Manually Adding an Oracle RAC Node to an Existing Instance

You can use this procedure when you want to add a new Oracle RAC node to an existing Oracle RAC instance.

This procedure is similar to the one that you use to add a new database to the Oracle RAC pseudo-client. You add the Oracle RAC nodes in each procedure.

You must follow these rules when you add a new Oracle RAC node:

  • Use the SYS login as the Connect string to connect to the database.

  • Do not include "/" when you select the Use SQL Connect option because there are multiple nodes.

If you want to use a SCAN hostname in the connect string for an instance, set the Connect string to: username/password@scan-hostname:1521/servicename. The service name is the database name. Use the physical node name in the scan Connect string because the backup process requires a pre-identified node for backup resource reservation.
