PMOD Software Installation
The computer for the PMOD license server doesn't require a high performance, but needs to be running continually. Therefore, a robust, vintage machine is well suited as a PMOD license server. Preferably, it is also dedicated to serving the PMOD license.
To install the PMOD license server first perform the steps described in the Stand-alone PMOD Installation including copying of the license file and plugging the USB key in.
Starting the License Server
The PMOD license server can then be started by executing the RunLcsSvr script in Pmod3.6/Start containing the following lines
#!/bin/sh
cd /opt/Pmod3.6
./java/jre/bin/java -Xmx2G -jar pmtsvr.jar 5000 -ls -d
The meaning of the command arguments is:
-Xmx2G: Size allocated to the license server
5000: IP port over which the license server communicates
-ls: license server only, no data sharing
-d: verbose output
Note: The script has been tailored to the installation directory. Therefore, if the Pmod3.6 directory is moved to a different location, the path needs to be adjusted.
Log Output
The command window will show startup information and log the checking out/in events as illustrated below.

Multiple Licenses Management
Multiple licenses can be served by a single PMOD installation. In order to use this feature please rename the different license files (pstarter.lcs) by appending the license numbers in square brackets (pstarter[1324].lcs, pstarter[427].lcs, ...) and copy them into the Pmod3.6/properties/system/lcs folder. There are two scenarios, a single license server managing multiple licenses simultaneously, or a separate license server for each license.
If the license server script RunLcsSvr.bat is started without modification, it will manage all licenses found in the directory. A specific license can then be defined in the RunPmod.bat script of the client by the command line option "-lsn[<PORT_NO>.<OPTIONAL_LICENSE_NO>@<IP_ADDRESS>", e.g.:
.\java\jre\bin\java -Xmx16G -jar pmod.jar -lsn[5000.1324@192.168.55.103] - to acquire license 1324
.\java\jre\bin\java -Xmx16G -jar pmod.jar -lsn[5000.427@192.168.55.103] - to acquire license 427
In order to operate a dedicated server for each license please create a separate server script for each license with the "-lic[<pattern>]" option included, e.g.
java -Xmx2G -jar pmtsvr.jar 5000 -ls -lic[1324]
java -Xmx2G -jar pmtsvr.jar 5001 -ls -lic[427]
A specific license can then be defined in the RunPmod.bat script of the client by the command line option "-lsn[<PORT_NO>@<IP_ADDRESS>" e.g.
.\java\jre\bin\java -Xmx16G -jar pmod.jar -lsn[5000@192.168.55.103] - to acquire license 1324
.\java\jre\bin\java -Xmx16G -jar pmod.jar -lsn[5001@192.168.55.103] - to acquire license 427
The advantage of separate servers is that the processes can be independently started, stopped and monitored.
Emergency Restart
In the case of connection or license management problems the following procedure is recommended for restoring clean license handling:
If this procedure is completed within 5 minutes, no shutdown of running PMOD clients is required.
