Patch Manager for NetWare 386 v3.10
Several patches have been released for NetWare 386 v3.10 rev A. Patches
for this version fall under three classifications: dynamic, semi-static,
and static.
Dynamic patches are .NLM files that can be loaded and unloaded while the
server is running. Unloading a dynamic patch will restore the
operating system to its original "un-patched" state.
Semi-static patches can also be loaded while the server is running, but
they cannot be unloaded. It is not possible to reverse the effects of
a semi-static patch without first bringing down the server and
bringing it back up without loading the semi-static patch.
Static patches are DOS executable programs that make changes to the
SERVER.EXE file. This type of patch is applied once and its effects
are permanent. We suggest that a backup of the original SERVER.EXE
file be made before applying a static patch.
Dynamic and semi-static NLM patches and static patches are managed and
tracked with a patch manager called PATCHMAN.NLM. Dynamic and semi-static
patches modify the operating system in memory, not on the disk. This means
that dynamic and semi-static patches must be loaded each time the operating
system is loaded in order for any fixes to take effect.
The NetWare Patch Manager and NetWare 386 v3.10 patches are available on
NetWire.
