About DBCA Noninteractive (Silent) Configuration for Oracle RAC

You can perform a noninteractive, or silent configuration of Oracle RAC using DBCA. To perform a silent configuration, you must have completed an Oracle Grid Infrastructure (Oracle Clusterware and Oracle ASM) installation, run the root.sh script from the Oracle Database home, and defined the Oracle home directory environment variable.

You can use DBCA to create a database from templates supplied by Oracle, or from templates that you create. The templates contain settings optimized for a particular type of workload.

Oracle provides templates for the following two workload types:

• General purpose or transaction processing

• Data warehouse

For more complex environments, you can select the Custom Database option. This option does not use templates and results in a more extensive installation interview, which means that it takes longer to create your database.
