Oracle DBCA – Database Configuration assistant.

Oracle provides several Configuration Assistant tools to facility administrative duties required by an Oracle DBA or Developer. The Oracle’s DBCA (Database Configuration Assistant) is the GUI tool used to create starter databases within the Oracle RDBMS. The DBCA utility was introduced in Oracle 8i and provides the user a GUI to eliminate the need for manual configuration of database creation scripts. In this article we will review the startup of the Database Configuration Assistant within a RHEL environment.

1. Logon to your Oracle Database server as the Oracle software owner.
2. Change directories to your $ORACLE_HOME/bin.

mylinux:> cd $ORACLE_HOME/bin
mylinux:>

3. Export your display to your local machine if you are not logon to the server itself.

mylinux:> export DISPLAY=192.168.0.110:0.0
mylinux:>

4. You will require a terminal emulation program executing on your local machine to produce the display from your database server. Any terminal display software will do, however I would suggest VNC which can be downloaded for free at the URL: www.realvnc.com

5. Execute the dbca shell script to startup the database configuration assistant.

mylinux:> ./dbca

6. The Welcome screen will display and the wizard from here on is pretty self explanatory. The DBCA utility provides you the ability to Create Databases, Configure Database Options, Delete Databases, Manage Database Templates, and Configure ASM instances for storage.
