3.7 Tasks to Complete Before Using DBCA to Create an Oracle RAC Database

Before you can create an Oracle RAC database using Oracle Database Configuration Assistant, you must configure your system to meet the software requirements, if this was not done as part of the Oracle Grid Infrastructure installation.

• Decide on a Naming Convention to Use for Your Oracle RAC Database
  The global database name for an Oracle RAC database must meet the naming requirements. The global database name consists of the database name and the domain name.
• Configure Shared Storage for the Oracle RAC Database
  Before starting Oracle Database Configuration Assistant (DBCA) to configure an Oracle RAC database, you must install Oracle Grid Infrastructure for a cluster, and configure shared storage areas for Oracle RAC files.
• Obtain the Password for the Oracle Home User
  If you use Oracle Database Configuration Assistant to create an Oracle Home User, then create an Oracle Home User password.
