This README file accompanies PATCHMAN.NLM v2.20. The following files
are included for this revision:
PATCHMAN.NLM 8,939 12-12-91 11:32a
PCHMN221.DOC (This file)
This version of PATCHMAN replaces any and all previous versions of
PATCHMAN. PATCHMAN v2.21 can only be used with NetWare v3.11+ (all number-
of-user versions). NetWare v3.10a requires PATCHMAN v1.20b.
*** PLEASE NOTE THE TECHNICAL BULLETIN ON THE 3.11 OPERATING SYSTEM
PATCHES INCLUDED BELOW.
PATCHMAN.NLM is the Patch Manager for which tracks and manages all
official patches for NetWare 386 v3.10+.
Patches for NetWare 386 v3.10+ consist of three types:
DYNAMIC -- Dynamic patches are implemented as .NLM files that
can be loaded/unloaded while the server is running. Unloading
a dynamic patch will restore the Operating System to its
original "un-patched" state.
SEMI-STATIC -- Semi-static patches can also be loaded while
the server is running, but they cannot be unloaded. It is not
possible to undo the effects of a semi-static patch without
first downing the server and bringing it back up without
loading the semi-static patch.
STATIC -- A static patch is a DOS executable program that
modifies the SERVER.EXE file. This type of patch is applied
once and its effects are permanent. It is suggested that a
backup of the original SERVER.EXE file be made before applying
a static patch. (In other words, do not patch the SERVER.EXE
on your original distribution diskette!)
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 brought up
in order for any 'fixes' to take effect. It is recommended that the
command "LOAD <patch>" be placed in the file server's AUTOEXEC.NCF
file to ensure that the patch is always in effect as soon as the
server is brought up.
In order to see which patches are currently loaded on the system, type
"PATCHES" at the file server command line. The patches will then be
grouped and displayed according to their type (i.e. - STATIC, SEMI-STATIC,
or DYNAMIC). Typing "MODULES" at the server console will show which dynamic
patches have been loaded, but will not show semi-static or static patches.
The Patch Manager (PATCHMAN.NLM) must be loaded before any dynamic
or semi-static patches can be loaded. If PATCHMAN is not already
loaded, the <patch>.NLM will attempt to locate PATCHMAN and, if
found, will load it automatically. PATCHMAN only needs to be
loaded once; all .NLM patches can then be loaded. PATCHMAN cannot
be unloaded until all patches that rely on it are first unloaded.
NOVELL TECHNICAL BULLETIN
TITLE: Effects of v3.11 Serialization Changes on
Patches and Fixes
DOCUMENT ID#: TB.P.298
DATE: 4 December 1991
PRODUCT: NetWare
PRODUCT REVISION: v3.11
SUPERSEDES: N/A
SYMPTOM: Errors, such as "Unexpected code encountered
in area to be patched" during implementation
of patches and fixes.
ISSUE/PROBLEM
Because of the unanticipated success of NetWare v3.11, the
available serialization range was exhausted. As a result, the
v3.11 operating system has been modified to extend that
serialization range. This modification has required a
corresponding change to all v3.11 operating system patches,
including those previously released. It does not affect any
patches or fixes other than v3.11 operating system patches. When
a user attempts to apply an unmodified NetWare v3.11 operating
system patch to a v3.11 operating system with the extended
serialization range, he or she may receive an error similar to the
one above.
SOLUTION
The modified NetWare v3.11 operating system patches can be applied
to any v3.11 operating system if the PATCHMAN.NLM (v2.20 or later)
that accompanies them is loaded at the file server. PATCHMAN.NLM
performs the application of a given patch to the v3.11 operating
system as it resides in file server memory.
Users should be aware of five important points:
1) PATCHMAN.NLM v2.20 (or later) must be loaded.
2) The modified patches, with PATCHMAN.NLM v2.20 (or later), will
successfully load on NetWare v3.11 operating systems without
the extended serialization range.
3) The re-released patches will not be successfully implemented
if PATCHMAN NLM v2.20 (or later) is not loaded.
4) Unmodified v3.11 operating system patches will work
successfully only on operating systems without the extended
serialization range. They will not work on a newly modified
operating system, nor on an operating system also running
modified patches or PATCHMAN v2.20 (or later).
5) The re-released NetWare v3.11 operating system patches are
dated October 1991 or later.
