Uninstalling a patch

5. Click Upgrade.
If the patch process is interrupted (for example, loss of power), you must restart the patch
process.
The patch installer performs the following functions:
•
Extracts patch files to the Install_Home folder.
•
Creates a back up (zip) of the original files to be updated and copies the zip file to the
Install_Home\patch-backup directory (for example,
Install_Home\patch-backup\na_11-3-0a.zip).
The first time you apply a patch, the back up patch zip file uses the following naming
convention: <Application>_<Major_Version>-<Minor_Version>-<Revision_Number>
<Patch_Version>.zip (for example, Install_Home\patch-backup\na_11-3-0a.zip).
Each additional time you apply a patch, the back up patch zip file uses the following
naming convention: <Application>_<Major_Version>-<Minor_Version>-
<Revision_Number><Patch_Version>-<Previous_Patch_Version>.zip (for example,
Install_Home\patch-backup\na_11-3-0-patch-a.zip).
•
Generates a patch log.
•
Updates the conf file (Install_Home\conf\patch.conf) to include the patch version applied
and patch created date.
•
Updates the patch version in the About dialog box (Select Help > About in the main
window).
6. Start all services by completing the following steps.

Uninstalling a patch
Note that only one set of back up files are retained which enables you revert back to the previous
version. You can only revert back one version. For example:

If you upgrade from patch A to patch B, you can revert back to patch A.
•
If you upgrade from patch A to patch B to patch C then to patch F, you can only revert back to
patch C.
