Software upgrade by installing hotfixes
Hotfix is a fast, cost-effective method to repair software defects of a device. Compared with software
upgrade, hotfix can upgrade the software without interrupting running services or rebooting the device.
Basic concepts in hotfix
1. Patch and patch file
A patch, also called patch unit, is a package to fix software defects. Generally, patches are released as
patch files. A patch file may contain one or more patches for different defects. After loaded from the
storage media to the memory patch area, each patch is assigned a unique number, which starts from 1,
for identification, management and operation. For example, if a patch file has three patch units, they are
numbered as 1, 2, and 3 respectively.
2. Incremental patch
An incremental patch means that the patch is dependent on the previous patch units. For example, if a
patch file has three patch units, patch 3 can be running only after patch 1 and 2 take effect. You cannot
run patch 3 separately.
The currently released patches are all incremental patches.
3. Common patch and temporary patch
• Common patches are those formally released through the version release flow.
• Temporary patches are those not formally released through the version release flow, but temporarily
provided to solve the emergent problems.
The common patches always include the functions of the previous temporary patches so as to replace
them. The patch type affects the patch loading process only; the system deletes all the temporary patches
before it loads the common patch.
Patch status
Each patch has its status, which can be switched only by commands. The relationship between patch
state changes and command actions is shown in Figure 12.
The patch can be in the state of IDLE,
DEACTIVE, ACTIVE, and RUNNING. Load, run temporarily, confirm running, stop running, delete, install,
and uninstall represent operations, corresponding to commands of patch load, patch active, patch run,
patch deactive, patch delete, patch install, and undo patch install. For example, if you execute the patch
active command for the patches in the DEACTIVE state, the patches turn to the ACTIVE state.
