Installing Oracle Database Software

Oracle Database Tips by Donald Burleson

The following steps will guide you through the process necessary to install Oracle Software.

1.      The installer CD 1 should be inserted into the CDRom on oracle1. Launch the oracle installer as the oracle user. Use the cd command to switch to the home directory of the oracle user, ensuring that the current working directory is not within the mount-point of the CD-Rom. It is important to be able to switch CDs! There should be no user with a current working directory as a subdirectory of the cdrom mount-point. Run the command /mnt/cdrom/runInstaller to launch the Universal Installer.

2.      Hold the shift key and click the nodes to select them all. If all the nodes are not visible, then Cluster Manageris not running on all of them, in which case, quit the install and start Cluster Manager on each node.

3.      If the $ORACLE_HOME variable is set properly, the path will be correct.

4.      Select Database software for install.

5.      Choose Enterprise Edition.

6.      Select Software Only.

7.      The file named as the Shared Configuration File was pre-created on shared storage using the dd command. Type in the full path and filename (case sensitive!).

8.      The summary screen will list the software that is about to be installed.

9.      To switch CDs, return to the terminal window from which dbca was launched. Press the [Enter] key to wake up the command prompt.

10.  Unmount the cdrom with the umountcommand, and then eject it. Place the next CD into the CDRom and wait a moment for the system to mount it. Then, return to the Installer window and click the OK button to continue the install. This step will have to be repeated again in order to switch to CD 3.

11.  The installer will ask that a script be run as root. Open a new terminal window. Use the suommand to switch to the root user and run the script. Accept the default value for the local bin directory by pressing [Enter]. Allow the script to finish on the first node before you begin it on the second. This step must be completed on each node.

12.  The entire software installation will require an hour or more on most systems. At the very end of the install, the Oracle Enterprise Managerwill open for no apparent reason. Just quit the OEM.

With the Oracle software installed, there are a number of tasks that must be completed before a RAC database can be created.
