Starting Oracle DBCA

Start Oracle DBCA in GUI mode to create and manage Oracle RAC databases.

  1. Log in as the software installation owner user, for example oracle.
  2. Start Oracle DBCA by running the following command:
    $ $ORACLE_HOME/bin/dbca

    Note:

    • 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.
    • For new installations of Oracle AI Database 26ai, Release Update 23.26, COMPATIBLE is set by default in the database to 23.6.0. You cannot change COMPATIBLE to an earlier release.
    • Starting with Oracle AI Database 26ai, Release Update 23.26, you can change the COMPATIBLE setting for all sessions in the current Oracle AI Database instance without having to restart the instance.
