Prepare for an Upgrade with a New Installation Directory

The installation procedure lets you select a new directory for the installation or use the default directory. In some cases, you want to use a different installation directory for a new version of the software when you upgrade CA Performance Center. This scenario requires extra steps during the uninstallation. The goal is to make sure that all the links from an initialization file that are related to CA Performance Center are removed.  The new installation can then get correct links for the variables that determine the location of the Device Manager, Event Manager, and other processes.

You can uninstall processes individually to clean up your installation directories for an upgrade that uses a different installation directory.

Follow these steps:

1. Navigate to the installation directory for the old installation.
2. Change directories to the DM subdirectory and then to the uninstall subdirectory.
3. Run the uninstaller for the Device Manager process:

   ./Uninstall_DM 
   

4. When the uninstallation of the Device Manager has completed, CD back to the installation directory, and then CD to the uninstall subdirectory of the EM subdirectory:

   cd ../
   cd EM/uninstall
   

5. Run the uninstaller for the Event Manager process:

   ./Uninstall_EM 
   

6. (Optional) Do a grep for the Device Manager and Event Manager variables:

   ls -al /etc/init.d  | grep cap
   

   The variables, caperfcenter_devicemanager  and caperfcenter_eventmanager, should not be present after a successful uninstallation of the Device Manager and Event Manager processes.

7. Uninstall CA Performance Center.
