3.6 Selecting DBCA Options to Create an Oracle RAC or Oracle RAC One Node Database

Review this information to use Database Configuration Assistant (DBCA) to create Oracle RAC or Oracle RAC One Node Database.

You no longer need to set the operating system environment variables ORACLE_HOME to the Oracle RAC database home, or ORACLE_UNQNAME to the database unique name.

Note:

You can no longer set up email notification for Oracle RAC databases either from DBCA or Oracle Universal Installer (OUI).

Starting DBCA
To start DBCA, connect as the installation owner account (for example, oracle) to one of your nodes where Oracle RAC is installed, load SSH keys into memory, and enter the command dbca from the $ORACLE_HOME/bin directory.
Cluster Detection and Node Selection when Using DBCA
When you start DBCA, it automatically shows Oracle RAC options if it detects from the central Oracle Inventory that the Oracle home is enabled for Oracle RAC.
Using DBCA to Select Storage to Use With any Oracle RAC Database
You can choose to use either Oracle ASM disk groups or a supported cluster file system as storage.
Selecting Server Pool Option with DBCA
When creating a database using Database Configuration Assistant (DBCA), you can choose the server pools to host policy-managed databases.
Using DBCA to Specify Database Initialization Parameters for Oracle RAC
Specify initialization parameters if you intend to add more nodes in your cluster.
