Title: Fix for 3+Open NBP Workstation Hang With PC/FOCUS Multiuser DBMS
Date: 03/18/91

Copyright 3Com Corporation, 1991.  All rights reserved.

There is a problem when PC\FOCUS Multiuser DBMS is run under 3+Open with
NBP.

PC\FOCUS requires a dedicated database server for database file integrity
and for the user workstations.  When a user exits FOCUS from his workstation,
the session between the database server (SYNC machine) and the user station
should be disconnected.  However, under NBP, the database server never
receives the request to disconnect from the workstation, and hangs until it
is rebooted.  If a user attempts to re-enter FOCUS before the SYNC is
rebooted, FOCUS will start in standalone mode only.

3Com has developed a new version of NBP to fix this problem.  The release
date of this new version is 11-1-90, and is called NBP 1.1y.  This file,
along with a new NBP.OS2 driver, is available in ZIP format in the Ask3Com
forum, Patches and Fixes library.  It is also the same version of NBP
currently released for LAN Manager 2.0.

To install NBP 1.1y, follow these steps:

1.  On each DOS Enhanced workstation, copy NBP 1.1y to this directory:

      \3OPEN\DOSWKSTA\LANMAN\DRIVERS\nbp.exe

2.  On the 3+Open fileserver, copy the new NBP.OS2 driver to this directory:

      \3OPEN\SERVER\LANMAN\DRIVERS\nbp.os2

3.  Copy the new NBP.EXE and NBP.OS2 files to these server directories:

      \3OPEN\SERVER\DOSDRV\nbp.exe
      \3OPEN\SERVER\OS2DRV\nbp.os2

Step 3 allows NETSETUP to grab the files when needed to configure a new
workstation.  Even after steps 1 and 2 are performed, the latter must also
be completed to allow new workstations to have the correct files.

4.  Set the class of operation used by the database server (not the
fileserver) to be Power-User or greater.

5.  Set the class of operation used by workstations to be Light-User or
greater.

In the PROTOCOL.INI file, the [NBP] section parameter DEFAULTS= controls
the class of operation for NBP.  Consult your 3+Open Tuning Guide pages 5-13
and 5-14 for information about the NBP protocol parameters.
