Release Date January 16, 1990Introduction
The LANimation(TM) Netware Application Software Control Program
consists of two programs and a data file which allow a network
administrator to control simultaneous access to any applications
software program on a Novell Network (Version 2.0a and above). This
is useful in those situations where a limited number of licenses
for a particular software package have been purchased, but access
is required from any station in the network (and the license allows
such access).
MEDIT Program
The MEDIT program is the administrative module of the package and
provides the tool necessary to set up your applications for
metering.
METER Program
The meter program uses the parameters you establish to control the
number of users simultaneously operating a particular program on
the LAN.
Installation for Experts
The MEDIT.EXE, METER.EXE, and the MET_CTL.FIL should be installed
in the PUBLIC directory of the file server. The MET_CTL.FIL should
be flagged Shareable, Read-Write, while the EXE files should be
flagged Shareable Read-Only.
Setting Up Applications to be Metered using MEDIT
After installation, log in as SUPERVISOR (with a search drive
mapped to PUBLIC). Execute the command MEDIT from the DOS prompt.
This should pop a window on the screen. The contents of the window
reflect the contents of the MET_CTL.FIL loaded in the PUBLIC
directory. You will notice that the file already contains an entry
for the TURBO.EXE program and this program has been set with a
maximum session count of 2. This means that any time the METER
program is used to start the TURBO.EXE program on this file server,
the number of other METERed TURBO users will be checked first and
if the simultaneous session count has been exceeded, access to the
program will be denied.
To insert a new application, press the INS key. The program will
ask you for the name of the program to be metered. Enter the name
of the command (without options or parameters) along with the
program's extension (COM or EXE). It is important to enter the
extension with the command name.
After entering the name, the program will ask for the number of
simultaneous sessions to allow. This number is the maximum number
of simultaneous users that you have licensed the software package
for. Enter the number of simultaneous sessions you wish to allow.
After completing input, the entry is added to the list. <ESC>
aborts input during data-entry. The <Del> key deletes an entry. To
edit an entry, highlight it with the up or down arrow keys and
press Enter.
That's all there is to it. Press <ESC> on the main screen to exit
the program.
METER Operation
To perform a controlled start of a program, simply issue the
command METER followed by the command you would normally use to
start the program:
>METER LOTUS COLOR
The METER program will check the network to see how many other
METERed copies of the LOTUS program are currently executing. If the
number is less than the number you specified, the METER program
will start up LOTUS along with the COLOR startup option. If all of
the LOTUS program's sessions have been exhausted, a message will
appear indicating there are no more sessions available. An
ERRORLEVEL of 6 will be set in this case.
METER will only count the number of other sessions of a program
which were also started with the METER command. Program copies
which were started conventionally are not registered. For this
reason, it is a good idea to use common batch files to start
METERed programs.
METER will execute programs across search paths.
METER will only work with .COM and .EXE files.
METER may be used to start programs that have not been set up using
MEDIT. METER will simply see that the program is not in the list
and execute the program without restriction.
METER requires about 10k of memory overhead from the METERed
program at execution time only (it is not a TSR).
Multi-Server Networks
The count of simultaneous users is maintained on a server-by-
server basis. That is each server's program counts are independent
of the others in the internetwork. When a user is logged-in to more
than one server and a metered program is executed, the server which
is checked is determined by the default drive mapping at the time
METER is executed. Therefore, if system-wide metering is required
in a multi-server network, make sure that the default drive points
to a central server prior to running METER. A version of METER
which overcomes this limitation, as well as shows real-time
statistics plus some other features is available from:
