Removing SF Oracle RAC using the uninstallsfrac utility

Run the uninstallsfrac script from any node in the cluster. Prior to invoking the uninstallsfrac script, you must take all service groups offline and shut down VCS.

The example procedure involves removing SF Oracle RAC from the node saturn.

 To remove SF Oracle RAC using the uninstallsfrac utility

1. As superuser, start the uninstallation.

   # cd /opt/VRTS/install

   # ./uninstallsfrac

2. Decline to uninstall SF Oracle RAC from all systems.

   VCS configuration files exist on this system with the following information:

   Cluster Name: rac_cluster101

   Cluster ID Number: 101

   Systems: galaxy nebula saturn

   Service Groups: cvm oradb1_grp

   Do you want to uninstall SFRAC from these systems? [y,n,q] (y) n

   Warning: Be sure to answer "n". Otherwise, the utility begins the process of uninstalling SF Oracle RAC from all systems.
   
3. Specify the name of the system on which you are uninstalling SF Oracle RAC.

   Enter the system names separated by spaces on which to uninstall SFRAC:saturn

4. Review the output as the script checks for packages currently installed on your system. The utility also checks for dependencies between packages to determine the packages it can safely uninstall and in which order.

   # /usr/sbin/shutdown -r now
