Uninstalling locally installed Oracle (optional)

If Oracle is installed on a cluster file system, skip to Running the uninstallsfrac utility.

If Oracle is installed locally and you choose not to uninstall Oracle, go to the next section, Unlinking the Oracle binary from the Veritas libraries.

If Oracle is installed locally and you choose to uninstall it, use the Oracle runInstaller utility. Run the utility on each system you are removing from a RAC cluster.

 To uninstall locally installed Oracle

1. On one system, log in as oracle.
2. Set the DISPLAY variable.
   • If you use the Bourne Shell (bash, sh or ksh):

     $ export DISPLAY=host:0.0

   • If you use the C Shell (csh):

     $ setenv DISPLAY host:0.0

3. Run the Oracle utility runInstaller.

   $ cd $ORACLE_BASE/oui/install

   $ ./runInstaller

   • As the utility starts up, be sure to select the option to uninstall the Oracle software from the local node you are removing.
   • Refer to the Oracle Installation Guide for additional information about running the utility.
