Incremental patch
Incremental patches are dependent on previous patches and cannot separately run. For example, if a
patch file has three patches, patch 3 can be running only after patch 1 and 2 take effect. You cannot run
patch 3 separately.
Patches that have been released are all incremental patches.
Common patch and temporary patch
Common patches are formally released to users.
Temporary patches are interim solutions that are provided to fix critical bugs. They are not formally
released.
A common patch always includes the functions of its previous temporary patches. The system deletes all
the temporary patches before loading the common patch.
Patch states
A patch is in IDLE, DEACTIVE, ACTIVE, or RUNNING state, depending on the patch manipulation
command.
Patch manipulation commands include patch load (load), patch active (run temporarily), patch run
(confirm running), patch deactive (stop running), patch delete (delete), patch install (install), and undo
patch install (uninstall).
For example, if you execute the patch active command, patches in DEACTIVE state change to the ACTIVE
state.
Figure 92 shows the patch manipulation commands and how they affect the patch state.
IMPORTANT:
Patch state information is saved in the patchstate file on the storage medium. To make sure the device can
correctly find the patches, do not edit, delete, move the file, or change the file name.
