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).
