If you have upgraded from a release prior to 3.3, you must remove the temporary files that are created as part of the upgrade process. These files can be used by Oracle Support to help you recover your environment if something goes wrong with your upgrade and you did not take adequate steps to backup your database before the upgrade. However, they also contain information about your entire environment that should not be left in temporary file space indefinitely.

It is important that you verify that your upgrade has completed successfully and that Oracle VM Manager is fully functional before you remove these temporary files. Log into the Oracle VM Manager Web Interface and check that your environment is configured as it was prior to upgrade. Check that you are able to perform actions on your Oracle VM Servers and storage via the Oracle VM Manager Web Interface. If your environment is functional, you can proceed with the removal of the temporary files generated by the upgrade.

To remove temporary files after upgrade, do the following as the root user on the Oracle VM Manager host:

# rm -Rf /tmp/workdir_sel*
# rm -Rf /tmp/ovm*

On many systems, temporary files are deleted automatically on reboot. If you have any concern about security after an upgrade, in most cases a system reboot ensures that these files are cleaned up properly.
