Uninstalling Oracle 10g (optional)

You can uninstall Oracle 10g or choose to run Oracle after uninstalling SF Oracle RAC. If you do not want to uninstall Oracle, then you must unlink the Oracle binaries from the Veritas libraries.

See Unlinking the Oracle Binary From Veritas Libraries

If you choose to uninstall Oracle 10g, use the Oracle runInstaller utility.

• If Oracle 10g is installed locally on each node, run the utility on each node.
• If Oracle 10g is installed on a cluster file system, run the utility once.

 To uninstall Oracle 10g

1. Log in as oracle user.
2. Set the DISPLAY variable. Depending on the shell you use, execute the following command:

    

   Bourne Shell (sh or ksh)	$ DISPLAY=host:0.0;export DISPLAY
   C Shell (csh or tcsh)	$ setenv DISPLAY host:0.0

3. Run the Oracle 10g runInstaller utility:

   $ /cdrom/Disk1/runInstaller

4. Select the option to uninstall the Oracle 10g software.

   Refer to the Oracle 10g documentation for details on this utility.

5. If necessary, remove Oracle 10g from the other nodes.
