Loading Hot Patch
A patch is a standalone software unit that is released to fix errors found in a system.
A hot patch can fix system errors without rebooting the device or interrupting network operation. That is,
it can upgrade the system dynamically.
Patches can be added to a patch file incrementally. That is, any subsequent patch file contains all the
patches for fixing errors in the previous patch file besides the patches for fixing the current errors. In this
way, all the system errors found can be fixed once and for all by loading the latest patch file.
In the device, a patch can be in one of the following four states:
z IDLE: The patch is initialized but not loaded.
z DEACTIVE: The patch is loaded but not activated.
z ACTIVE: The patch is active but not running.
z RUNNING: The patch is running.
The difference between active patches and running patches:
z After system reboot, an ACTIVE patch becomes DEACTIVE and stops working;
z After system reboot, a running patch remains running.
The active state provides a buffer to help prevent the system from running with errors introduced by the
by the patches.
Any state of the four cannot be switched to another without user intervention on the command line.
Figure 4-1 illustrates how patch states change with commands:
