the theoretical maximum number is 65535 (actually it is limited by memory space,
so the maximum number set for the FAM patch is 200).
A patch file includes all the patches that are installed for the same basic version.
Patches are released in the form of patch files. Corresponding patch description
files are also released together with the patch files. A patch description file
describes detailed information of a patch, such as problems this patch file can solve,
patching precautions, and so on.
III. Easy for installing patches
An operator can perform software patch installation through MML commands
without stopping the running of the system, so as to recover the faults.
Caution:
Because online software patching affects the operation of software in CPU, only the
system administrator can perform this operation.
IV. Self-healing capability
When the system is faulty, such as system power failure or abnormal restart,
patched modules in the FAM can automatically restore to the previous patched
status.
