Hi,

You need to set the following environmental variable in your system.

ILOG_LICENSE_FILE

and set to the location of your license file.

Cheers,

I had already done that. It still doesn't work.

Can you try to follow the instructions in the FAQ below

and see if that solves your problem?

Thanks. That solved it. My text editor must not have saved it as a txt file.

Hello,
I followed the instructions indicated at:
http://www.ibm.com/developerworks/university/support/ilog.html
http://download.boulder.ibm.com/ibmdl/pub/software/dw/university/support/ILOGQuickStart.pdf

Everything is fine: My access file access.ilm has no .txt extension. The environment variable points to the good folder.

However, I am still getting the error message:
cplex: CPLEX Error 32201: ILM Error 16: CPLEX: license file not found or unreadable
(see http://support.ilog.com/faqmsg?m=ILM-16&v=2.62f).

Whatb should I do?

What operating system are you using?

Does this happen when you run the CPLEX interactive optimizer from a terminal/DOS prompt, or when you run code that uses one of the APIs, or both?

I happen to have the similar problem.
The CPLEX interactive optimizer works properly, whileas the API (concert technology with C++) method fails all the way, with the license error same as above.

update: CPLEX now functions as expected. Didn't change anything but the license error suddenly disappear. No idea.

I have a similar problem.
My Cplex works fine interactively but when I submit a cplex job to the cluster I am getting the license file not found error message!

echo $ILOG_LICENSE_FILE
/cs/public/lib/pkg/cplex/ILM/access.ilm

which cplex
/cs/public/lib/pkg/cplex/CPLEX_Studio_AcademicResearch122/cplex/bin/x86-64_sles10_4.1/cplex

Any suggestions?

Thanks,
Hannah

Are you sure that the environment in which your application runs on the cluster has the ILOG_LICENSE_FILE variable set?
What job do you submit to the cluster? Is that a program written by you (in which API) or is it the interactive optimizer?

I am trying to run someone else's code to optimize my big set of parameters (~750 parameters).
I am writing a script, which sets the variables and connects to the cluster and runs cplex then.

I tried writing the following lines in the script that calls cplex on the cluster to make sure the cluster environment is the same as mine.
"ILOG_LICENSE_FILE=/cs/public/lib/pkg/cplex/ILM/access.ilm/access.ilm\n"
"PATH=/cs/public/lib/pkg/cplex/CPLEX_Studio_AcademicResearch122/cplex/bin/x86-64_sles10_4.1/:\$PATH\n";

but it did not work.
I even tried:
"export =/cs/public/lib/pkg/cplex/ILM/access.ilm/access.ilm\n";
"PATH=/cs/public/lib/pkg/cplex/CPLEX_Studio_AcademicResearch122/cplex/bin/x86-64_sles10_4.1/:\$PATH\n";

and it did not work either!
any suggestions?

As a first test I would try to launch a script that echos $ILOG_LICENSE_FILE instead of the CPLEX binary on the cluster. This will then show you if the environment variable is set up correctly.

The path to the license file had a slight error in it.

Solution to the error "license file not found or unreadable". Worked for me.

I use Linux system and Eclipse to program in Java. I am getting license error as follows

Error 32201: ILM Error 16: CPLEX: licene file not found or unreadable (see http://support.ilog.com/faqmsg?m=ILM-16&v=2.61c).

I can see that environment has been set up correctly from inside Java program, and I can even read the text in the license file.

Any ideas?

Just to be sure, these two lines both print "true" from inside your application:

System.out.println(new java.io.File(System.getenv("ILOG_LICENSE_FILE")).isFile());
System.out.println(new java.io.File(System.getenv("ILOG_LICENSE_FILE")).canRead());

If they do, how did you obtain your license file? Did you copy/download the file from somewhere or did you copy-and-paste its content from somewhere? Copy-and-paste is a bad idea since this may introduce unwanted characters like DOS line breaks etc.

Thanks for reply.

I didn't even copy the license file - it is the file used by our currently running system. This license file has to be good otherwise our program shouldn't be running.

As for the Java file reading, I can see that it works correctly because my program dumps the content of the license file by reading it.

This is puzzling to me. Any idea is appreciated

Did you double check that your ILOG_LICENSE_FILE environment variable is set correctly (for example using the two statements I provided)?
When you open your file for dumping it from the application, how do you specify the filename? Do you explicitly give it or do you use the ILOG_LICENSE_FILE variable? Does this dump the file correctly

final BufferedReader br = new BufferedReader(new FileReader(System.getenv("ILOG_LICENSE_FILE")));
for (String line = br.readLine(); line != null; line = br.readLine())
   System.out.println(line);

Do you have multiple versions of CPLEX installed on your machine? If so, are you sure the license file is for the CPLEX library you are using with your Java application?

Hey

Thanks it works now.

The mistakes that I made are

1) Using -DILOG_FILE_NAME as JVM parameter to specify the environment variable

I should use Linux/Bash export ILOG_FILE_NAME=...

2) Using System.getProperty(,) for testing.

I should use System.getenv() for testing

Thanks again, Jeff
