If you use the 2.11 version f Netbios, you may run into timeout problems, since
Netware's default timeout (30 secs) is less than the Netbios timeout values
used by MDBS (128 secs). To make Netware's timeout value higher than MDBS's,
put NETBIOS ABORT TIMEOUT = 2559 in each CPU's SHELL.CFG. This is the maximum
allowable value and raises Netware's timeout to about 140 secs.
Use of the -e parameter on the MDBSDMS (or MDBSRTL) command line can greatly
improve performance. MDBSDMS is a small memory model program, but the -e
parameter allocates some or all of the remaining 640 KB as a write-through
cache for MDBS's page buffers. If the pool size you specify with this
parameter exceeds the amount of available memory, you will get a mesage to that
effect, reporting how much memory was found and used. The number reported,
however, is modulo 256; e.g., the program might use 330 KB and tell you it is
using 74 KB. Of greater interest to you is that there are some bugs with the
-e support in the initial release that may cause random corruption to your data
base.
There is another bug in the initial 3.09 MDBSDMS where a routine that purges
ghost IDs sometimes gets overzealous and purges valid IDs, resulting in an
unexpected DMS error 38 at a work station. MDBS fixed this in a maintenance
release, but their software control procedures are sloppy at best and the bug
crept back into later maintenance releases. (continued...)

(...continued) Depending on various factors, possibly including your page size,
the number of members in various sets and your use of duplicate sort keys, you
may run into a bug, where some perfectly valid operations of yours may leave
some internal data base pointers inconsistent. This bug is known to MDBS as
the "DMS 114" problem. This is another bug which was fixed but has crept back
into later maintenance releases.
If you should get a maintenance release from MDBS, watch out for a version of
MDBSNETM.EXE that is about 60 KB. This version has a bug which, depending on
your use of the -e performance option, can produce random and rampant
corruption of your data base.

Dear John,
One of my clients received the following message on their LAN:
'DOS network return error 15h (8h) during communications'
Thjey are currently running SFT NetWare 2.11 on their IBM AT system with a
Maxtror 1140 hard disk type 9. The topology is SMC/Pure Data ARCNET with about
11 or 12 workstations attached.
On this particular LAN, the clkient has been running solomon accounting for
several years. Needless to say, the client had their Solomon consultant (at
least he calls himself that) install the latest version of Solomon with a
dedicated database server. This database server is the Compaq 386/20 with a
130MB hard disk installed. From what I know of Solomon, this new version
requires that NETBIOS be loaded. Of course, the INT2F application had also been
loaded where applicable. Is there anything I can check on the LAN side, or is
this something that may be software related.
Thanks in advance.

The message is being issued by MDBS III, the DBMS product used by Solomon III.
The version of MDBS III you are using uses Netbios calls to communicate between
work stations and the data base server. MDBS III reports Netbios error returns
in the manner your client saw. MDBS, in its often user-unfriendly manner,
expects you to have the IBM PC Network Adapter Technical Reference, which
describes the Netbios error return codes. Error 15H is "Name not found, cannot
specify *, or 00H". Error 8 is "Illegal local session number". I have never
seen a 15H from MDBS, and I have seen error 8 only occasionally, when a work
station reboots following a crash.
Is the error occurring on the data base server (this is _not_ the file server)
or on a work station? Is the problem repeatable?
