MATLAB: Doesn’t the installer create a SERVER / USE_SERVER client license file for all platforms

MATLAB

When I install a concurrent client on UNIX, Linux, or Mac, the installer doesn't create a SERVER / USE_SERVER license file as it does on Windows.

Best Answer

Releases prior to R2008a will not create a SERVER / USE_SERVER license file because the Linux installer requires the TMW_ARCHIVE line for installation. Thus, the "INCREMENT TMW_ARCHIVE" line, along with all the other INCREMENT lines, is left unchanged by the installer.

However, installation is actually possible with a SERVER USE_SERVER type license file, as long as it points to an existing server that has an INCREMENT TMW_ARCHIVE line. You can manually create this file, using the SERVER line from the license manager as the SERVER line, and USE_SERVER as the second line. For example:

SERVER serverName serverAddress TCPport

DAEMON pathToVendorDaemon

INCREMENT TMW_ARCHIVE

INCREMENT MATLAB

ect..

would become

SERVER serverName serverAddress TCPport

USE_SERVER

MATLAB: Do redundant servers fail to run properly if the primary server is killed

This issue can occur if the MATLAB client points to the license servers via a license file instead of using the MLM_LICENSE_FILE variable. After the installation is complete the client license file should be removed and an environment variable used in its place. The client license file for MATLAB will be one or more of the following:

For R2008a and higher:

$MATLAB\licenses\network.lic

For pre-R2008a:

On Windows the client license.dat file is located in $MATLAB/bin/win32.

On UNIX/Linux/Mac this license.dat file is placed in $MATLAB/etc.

(where $MATLAB is the installation folder for MATLAB)

The environment variable that should be added is as follows:

MLM_LICENSE_FILE=port@server1,port@server2,port@server3

-port refers to the number at the end of the SERVER line in the license file. By default this is 27000.

-server refers to the hostname of your server as defined in the SERVER line of the license file.

NOTE: The entries in the environment variable must be separated by commas (","), not semicolons (";") or colons (":").

This step allows client redundancy so that if a server fails while a client license is checked out the client will search to the next server instead of posting an error. This also will remove the need to update the client license files if the server license files are changed.

MATLAB: Using two license servers

This answer may help you.

You can specify first and second license servers using MLM_LICENSE_FILE environment variable.

Add a new environent variable MLM_LICENSE_FILE in Windows, Linux or Mac and set the value as

Windows

port1@licenseserver1hostname;port2@licenseserver2hostname

Linux/Mac

port1@licenseserver1hostname:port2@licenseserver2hostname

Or, you can also specify the license files.

For example, first, rename license files as network1.lic (for accessing license server1) and network2.lic (for license server2).

And set environment variable MLM_LICENSE_FILE as follows.
