.ce CNFGLS13 - A spreadsheet
.ce to generate a 'starting point' LAN Server 1.3 Configuration
:ehp1.
.sp2
:hp2.Overview:ehp2.
:p.CNFGLS13 is an EXCEL (tm) (V2.2) or LOTUS (tm) (123 V3.0, 123/G)
spreadsheet which will generate, for a LAN Server configuration, an
IBMLAN.INI file and OS/2 Communications Manager configuration
parameters which are required to run a the Server. It may be
used for an initial setup of a Domain Controller or Additional Server.
It will take into account Communications Manager 802.2 requirements
for other functions in addition to the server which might be running
on the server machine. These include other NETBIOS applications,
SNA Gateway, APPC, RDS, IBM LAN Network Manager and 802.2 applications.
:p.
The generated INI file is complete, and it may be cut from the
spreadsheet, pasted into an editor session and saved directly into the
IBMLAN subdirectory if you use EXCEL. 123 users can copy the generated
parameter settings and enter them into the IBMLAN.INI file manually.
Look in column I to see the values you'll need to change.
Or, look at the generated INI file - the changed parameters will be
found to the right of the INI parameter names (except for SRVHEURISTICS).
SRVHEURISTICS changes too, so make sure you copy them down!
Any changes to text strings (server name, domain name, server services)
are handled like the SRVHEURISTICS, so check to be sure you get 'em.

:hp2.Running the spreadsheet:ehp2.
:p.
When you load the CNFGLS13 spreadsheet, you will see columns A-D
and rows 1-22 displayed. Column headings are furnished to help you get
oriented. There are several questions which you must answer about your
server before a configuration can be generated, and they are in column A
under the heading 'Questions to Answer'. Your answers will be entered
in column B under the heading 'Response'. Where help may be needed to
explain what is meant by a particular question, column C ('Comments')
provides additional information. As your responses are entered and
checked, error messages may be displayed in column D ('Potential Errors')
which you should monitor during data entry. Correct any entry errors as
they occur. One question, number 7, has caused some confusion. It asks
for the 'number of apps shared'. What it does with the number entered is
straightforward. It multiplies it by 3 to get the first cut at MAXSHARES
and later adds the responses to question 11 and 13 to that for the final
result you will see in the generated INI file.
:p.
Under the questions on the first screen is a second screen of questions
which furnish information necessary to generate Communications Manager
NETBIOS and 802.2 configuration parameters required to support a
variety of additional communications functions you may have.
The last of these questions can be used if you want the server to
also be used as a 3270 workstation (not a Gateway). Say you have one
application, then say how many stations you'll need. Usually, this is 2.
:p.
Under these questions in column A is an additional 'Errors Encountered'
message area. As your configuration is generated, storage maps are
generated internally and checked to make sure your server has enough
memory, that you do not have other potential errors for which the
spreadsheet checks, That your NetBIOS work area will be able to contain
all the resources required by your configuration,
that your Token-Ring Adapter will have enough RAM for your configuration
and that you do not have too many machines in your Domain.
:p.
You should ensure that 'OK' or 'None' appears in column B for each of
these tests before attempting to use the generated configuration.
Some errors may be diagnosed in Column K. If these occur, the message
you see will direct you to it for further information. Most of these
merely indicate you have reached a parameter's maximum limit - they
can generally be treated as warnings.
:p.
Do NOT use the 'memory map' feature to configure the minimum memory
required for a server. Performance of a minimum configuration may be
minimal.
:p.
Starting in cell A68, you will find your generated INI file. It ends
in row 201, and is a complete INI file which should require no
modifications by you. Cut it out, paste it into an editor session and
save it into the server's IBMLAN subdirectory as IBMLAN.INI, and you
are ready to go. Doing this requires Excel. 123 users will have to copy
the generated parameters down and enter them into the INI file manually.
123 users should note the NET1 statement does not have required ','
characters in it. These commas should go between the Xn parameters.
:p.
Starting in cell A221, you will find the CM IEEE 802.2 configuration
recommendations. Starting in cell A230, you will find the CM NetBIOS
configuration requirements for the server function ONLY. Finally,
starting in cell A238, you will see a recommended cache value
for your server and the statements required in your CONFIG.SYS to enable
the HPFS file system. The spreadsheet does not take all available memory
in the server, but leaves some to allow for dynamic allocation of memory
by other functions (EG spooler, dynamic bigbuffs, NET RUN, Admin, etc.)
:p.
Make a note of these parameters, and use them to adjust your CM
configurations as required. To do this, at your server you should
go to the Task Manager (Crtl-Esc), select
Communications Manager->Advanced->Configuration, specify the
configuration file name which is used in your CONFIG.SYS on the
device driver statements for the Token-Ring Network, and press Enter.
Then, select LAN feature profiles. At the LAN Profile Configuration
screen select adapter 0, and the interface you want to update. Then
fill in the appropriate fields on the displayed configuration.
:P.NOTE: The most common problem users have with the spreadsheet is
caused by not updating the CM configuration files. Be sure
to do this! And be sure your CONFIG.SYS device= statements
point to the configuration files you are updating in CMLIB.
:p.
After the configuration changes are made to IEEE 802.2 and NetBIOS,
and you are back at the LAN Profile Configuration screen, press ESC,
and (at the Communication Configuration Menu screen)->Verify. Once
the configuration has been successfully verified, exit the CM function.
:p.
IPL to restart, and your server should startup and run without error.
:p.
If it doesn't, you may have installed it on D:. The NETLOGON path points
to C:. You'll have to modify the INI file to fix this to point to D:.
The symptom of this problem is a failure to start NETLOGON services.
:pa.
:hp2.Nitty-Gritty Stuff:ehp2.
:p.
For those of you who want to see more than was just described,
return to the top of the spreadsheet (Ctrl-Home) and move the
cursor to columns G and H.
Here you can see the formulas and intermediate
results generated during the spreadsheet run.
:p.
If that isn't enough for you, continue to columns I, J and K.
In this set of cells are the final calculations for generating the
INI values used in the generated parameter file. Notice that column K
is still another 'error' check. Here you will find indications of
generated parameters which are pushing the limits of the LS 1.3 product.
:p.
STILL not satisfied? OK, move to columns L and M. The 'Memory Required'
numbers are pretty much from the Announcement Letter, but have been
checked to be sure they are still valid.
:p.
Columns P & Q show assumptions
which have been made in the spreadsheet to make your job (and mine)
a bit easier. The most important one to note is that a Token-Ring
16/4 Adapter is assumed to be used. If your server is an AT with the
original 8KB adapter, the generated configuration may fail to run
properly.
:p.
Now, if you're still hanging in there, move to columns S and T, and
you'll see still another work area (will we never run out of them?)
This is used to convert yes/no answers to manipulable numbers, and to
help us stay organized.
:p.
But wait! There's more! Move to column AA, and you'll see still
more fascinating stuff - in this case a list of all the error messages
which can be output. We had to put them somewhere.
:p.
Oh, yeah! You'll find, if you like to explore spreadsheets (and
have nothing better to do with your time) a few other things scattered
here and there. Don't mess with them!

:hp2.Secret Stuff:ehp2.
:p.
If you haven't noticed yet, the spreadsheet is protected so the
innocent cannot hurt themselves. If you insist on having that
privilege, the password is 'sstuner'. Use it with care. Be gentle.
:P.
Good installing!
