Software upgrade by installing hotfixes
Hotfix can repair software defects of the current version without rebooting the device, protecting the
running services of the device from being interrupted.
Basic concepts in hotfix
Patch and patch file
A patch, also called “patch unit”, is a package used to fix software defects. Patches are usually released
as patch files. A patch file may contain one or more patches for different defects. After loaded from the
storage medium 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.
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 run only after patch 1 and 2 take effect. You cannot run
patch 3 separately.
Currently released patches are all incremental patches.
