Web site, www.globetrotter.com. You can also go to the support page on the MathWorks Web site, www.mathworks.com, and find additional information about a particular license manager error.
License Manager Error -2: Invalid License File Syntax
This error typically indicates that there is a problem in your License File.
On client systems, make sure your License File has the following format.
Note that there should be a carriage return immediately following the USE_SERVER line.
License Manager Error -3: Cannot Connect to a License Server.
This error can occur if the SERVER line in your License File is incorrect or missing.
SERVER line in your License File matches the SERVER line in the License File on your license server. On Windows systems, the license.dat file on the client can be found in $MATLAB\bin\win32. On UNIX systems, it is located in $MATLAB/etc on UNIX/Linux machines.
| Note You must restart the license manager after making any changes to the License File on the license server. |
SERVER line in your License File is not already being used by another application. Change the port number on the SERVER line to a port that is not being used. FLEXlm has reserved ports in the range 27000 to 27009. Restart the license manager after making this change.
mlm) running. Check your FLEXlm log file for the error "Multiple MLM Servers Running."
License Manager Error -5: License Checkout Failed. No Such Feature Exists.
This error usually indicates that you are trying to use a product for which you are not licensed.
#, SERVER, DAEMON, or INCREMENT and replace any tab characters in INCREMENT lines with spaces.
| Note You must restart the license manager after making any changes to the License File on the license server. |
License Manager Error -6: No TCP "License" Server Exists
This error can occur if a SERVER line does not specify a TCP port number, and the TCP license service does not exist in /etc/services.
SERVER line in your License File contains a TCP port number, typically 27000.
telnet hostname command where hostname is the name of the computer running the license server. If the telnet command does not connect to the specified hostname computer, there is a problem with your network configuration. You must resolve this problem before you can run MATLAB.
License Manager Error -8: Encryption Code in License File Is Inconsistent
The passcode in an INCREMENT line does not match the other data in the license file. The log file, usually named /var/tmp/lm_TMW.log, should indicate the specific INCREMENT line where it found bad codes in your License File, $MATLAB/etc/license.dat.
01-mar-99 instead of 01-mar-2002. The date format should always match the passcodes that were sent by e-mail or faxed to you.
License Manager Error -9: Invalid Host
The host ID specified in the License File does not match the node on which the software is running.
SERVER line in your License File.
lmhostid command on the node. If the host ID returned is different from the host ID in the License File, contact The MathWorks for new passcodes. See Obtaining or Changing Your License File for more information.
License Manager Error -10: Feature Has Expired
This error indicates that one or more of your license keys has expired.
INCREMENT lines in your License File. If the dates in the license file have already passed, contact the Customer Service department at The MathWorks (through the Web or through e-mail at service@mathworks.com). When contacting The Mathworks, include your License Number and the host ID of your license server.
License Manager Error -11: Invalid Date Format in License File
This error indicates that the start date or the expiration date in the License File is invalid. This can happen if the expiration dates in the License File have been changed.
You can also get this error if the space character between the number of users field and the 20 digit encryption code in the INCREMENT line is missing. Compare the INCREMENT lines in your license file with the INCREMENT lines in your original license e-mail. They must be exactly the same.
This error can also occur if the SERVER and DAEMON lines are missing from the license.dat file. The installer adds these lines to the License File as part of the installation process.
License Manager Error -12: Invalid Returned Data from License Server
This error occurs when incompatible daemons are running. Most often this error is caused by doing an upgrade installation of MATLAB in the same directory as the previous version where the daemons were not shut down before the update was installed. If the daemons are not shut down, then an update of MATLAB will not replace the daemon files.
$MATLAB/etc/lmstart to start the license manager and vendor daemons corresponding to the current version of MATLAB.
License Manager Error -13: No SERVER Line in License File
This indicates that there is no SERVER line in the License File. This line should be added by the installer during the installation process.
To remedy this problem, run the installer again or manually edit the License File, $MATLAB\flexlm\license.dat, adding the SERVER line. See License File for information about the format and contents of the SERVER line.
License Manager Error -14: Cannot find SERVER Hostname in Network Database
The gethostbyname() system call failed for the SERVER name in the License File. The license server and the client running MATLAB are in different domains. The local hostname listed in the License File cannot be resolved on the remote domain.
To fix this problem, perform this procedure:
telnet to log in remotely to the server computer (using the fully qualified name) from itself and from a client. If the telnet connection succeeds, then the fully qualified name is resolvable.
License Manager Error -15: Cannot Connect to License Server
The license manager could not connect to the vendor daemon on the SERVER node. This error is displayed when starting MATLAB.
hostname command where hostname is the name of the license server. If telnet does not return a successful session on hostname, there is a problem with your network configuration. You must resolve this problem before you can run MATLAB. Contact your local system administrator for help
License Manager Error -16: Cannot Read Data from License Server
This error indicates that the path to the MATLAB vendor daemon, mlm.exe, is incorrect in your License File DAEMON line. See License File for an example of a DAEMON line.
License Manager Error -18: License Server Does Not Support This Feature
The feature has expired (on the server), has not yet started, or the version is greater than the highest supported version.
INCREMENT line in your License File exactly matches the INCREMENT line in the license information you received from The MathWorks. Check for typographical errors.
License Manager Error -21: License File Does Not Support This Version
If you are getting this error on your license server, make sure you have installed the version of FLEXlm included with Release 13. Release 13 License Files will not work with the older FLEXlm versions.
If you have updated an existing license.dat file with new Release 13 passcodes, you still need to install FLEXlm 8.0d from the MATLAB CD.
If you are getting this error on one of your client systems and not on the server, make sure the License File on the client is in the following format.
The SERVER line in the client system License File should be the same as the SERVER line found in the License File on the license server.
Also, make sure you are using your Release 13 license and not a license from a previous release.
License Manager Error -25: License Server Does Not Support This Version of This Feature
This error indicates that you are trying to run MATLAB 6.5 with an old license. You must update your license.dat file with your new license passcodes.
If you do not have your Release 13 license, contact Customer Service at The MathWorks.
License Manager Error -31: Feature Not Yet Available
The current date is before the feature start date. Check the log file for the name of the feature.
INCREMENT line in your License File exactly matches the passcode in the license information you received from The MathWorks. Check for typographical errors.
date command at the UNIX prompt.
License Manager Error -39: No License for Feature
You are not listed as a user in your options file.
INCLUDE line for the product you are trying to use. The installer creates the options file, named $MATLAB/etc/MLM.opt.
License Manager Error -83: FLEXlm Version of Client Newer Than Server
This error message usually indicates that the version of the license manager on the client system is newer than the license manager on the server system. When MATLAB starts, the license file is pointing to the wrong version of the license manager.
To correct the problem, change the path of the DAEMON line in your license.dat file. For a UNIX server, the DAEMON line for all license files should resemble this sample (the path of your daemon will be different).
For a PC server, the DAEMON line for all license files should read
where $MATLAB is your MATLAB installation directory. After changing your License File, be sure to restart the license manager.
License Manager Error -84: Missing Options File
This error typically indicates one of these conditions:
DAEMON line in you License File does not include the path to the options file
$MATLAB\flexlm\MLM.opt, where $MATLAB is your MATLAB installation directory.
DAEMON line in your License File.
INCLUDE lines in your options file.
License Manager Error -88: License Checkout Failed
This error indicates that your system clock has been set incorrectly. Check that your system date and time are correct.
License Manager Error -96: Server Node is Down or Not Responding
This error can occur if you are running DHCP (to obtain a dynamically assigned IP address) on your license server. MATLAB cannot connect with the License Manager because it uses TCP/IP protocols for communication and your IP address is changing.
To fix this problem, follow this procedure.
ifconfig command. On a PC running Windows, you can use the ipconfig command at a DOS prompt.
/etc/hosts file. On Windows NT and Windows 2000 systems, edit the C:\Winnt\system32\drivers\etc\hosts file.
License Manager Error -97: License Checkout Failed
This error is often caused by trying to run both MATLAB 5.3 and MATLAB 6.5 on the same system with different license managers. If this is the case, run both copies of MATLAB with the same License File. See Running Multiple Versions of MATLAB for more information.
If you are not trying to run MATLAB 5.3 but only want to run MATLAB 6.5, make sure you have installed FLEXlm version 8.0d from the Release 13 CD. MATLAB 6.5 will not run with an older version of the license manager.
