What is a companion license? A companion license grants license portability to a fixed product license. Each fixed product can be assigned to up to three computers: an office, a lab, and a home computer as long as all are only used by the same person. The license restricts the user to only one computer at a time. What is a checkout license? A checkout license enables portability for users with only floating seat licenses. The license administrator can issue a two-week fixed license allowing one of the users to have access to the same product licenses from the network while traveling with a laptop.
Why hasn't my license file arrived by email yet? Although most license files are sent a few minutes after they are requested, it may take up to 24 hours for you to receive a license file after requesting it. You will not receive the license file if the email address provided was incorrect. How do I set up a license? Do I need to activate my software? I want to know the reason why this error Fatal intialization error occurs. License error, Error server not connected. I am still an Engineering student.
How can I get a free QuestaSim license? License renewal for the student version Automatic session termination of the license on the server. I have a new Workstation. Do I need a new License File? New licenses provided do not recognize features. Topics Show Topics. Siemens Digital Industries Software. The specified directory must exist and be writable by the user invoking the client application. If the directory does not exist or is not writable, then no debug log file is generated.
Each invocation of the application starts a new log file. Therefore, no log files are appended to or overwritten. The licensing default is fifteen days, but some sites may require earlier notification. The first method uses the pathname of the license file. This allows you to contact a license server without having to know the pathname to the license file the license server is using. The list is a colon-separated list of feature names that licensing searches from left to right. You should include the keyword ANY at the end of the list, which allows licensing to use any available license to satisfy the request after it checks the other licenses listed.
The MGLS options file is a text file that is usually stored in the same directory as your license file. These two files are mutually exclusive, where options in one file do not affect options in the other. During installation, the licensing software sets the necessary values in the system registry.
Setting Environment Variables on Windows The licensing installation software sets the necessary registry settings during configuration. If the values need to change, you can try running the Configure Licensing menu item to change the values. The list is a semicolon-separated list of feature names that licensing searches from left to right. You can include the keyword ANY at the end of the list, which allows licensing to use any available license to satisfy the request after it checks the other licenses listed.
For an example, refer to Figure Use of the daemon options file is optional; you only need to use it if you want to restrict or customize license usage. Information about the location of the daemon options file and how to reference it appears in the following section.
An example daemon options file appears on page These two files are mutually exclusive, where options in one file do not affect options in the other file. If you want to use a daemon options file for example, you want to add custom information for your site to this file , you will also need to edit the license file with the correct pathname to the options file and restart the license server for the options to take effect. The licensing software locates the options file by the pathname you enter as the fourth field in a DAEMON line in the license file.
For example, if you name the options file mgcld. Because the daemon options file is associated with the mgcld licensing daemon, any feature you name in the daemon options file following a keyword must be supported by the mgcld daemon.
For information on more of the option keywords, refer to the License Administration Guide. Example Options File The following shows an example daemon options file Note: There are more command possibilities than those shown.
And, at least one calibredrc license will always be reserved for HOST bigengine. USER randy will always be prevented from using qhsimvh licenses. Messages for queued licenses are not logged. For more information, refer to the License Administration Guide.
Controlling License Consumption There may be many different types of licenses on your network that will authorize the same application.
Also, any station, composite, or option license can be nodelocked or floating. If you have a license file that contains multiple types of licenses for the same application, you might want to control the order in which licenses are consumed. You can only designate a nodelocked license for one particular system in your network, while you can use a floating license for any system in your network. Using up a floating license, when a node-locked license is available, deprives one user of a floating license and leaves the node-locked license idle, since no other workstation can use it.
When you consume a station license for a given application, the license offers broad functionality, but only the user holding the station license can use applications associated with that station license. The first mechanism uses the order of the license file entries to determine which license to check out. If Feature2 appears before Feature1 in the license file, and both licenses can satisfy the license request, Feature2 will be used if it is available for check out.
The second mechanism applies to license entries with the same feature name. During execution, the application program communicates with the vendor daemon to request a license.
The lmgrd daemon handles the initial contact with the client application programs, passing the connection to the appropriate vendor daemon. It also starts and restarts the vendor daemons. In FLEXnet, licenses are handled by running processes. The vendor daemon keeps track of all the licenses that are checked out and who has those licenses.
For Mentor Graphics products, this vendor daemon is named mgcld. The disadvantages include more maintenance overhead, difficulty tracking all licenses, and non-centralized licenses. Merging License Files It is also possible for you to have one license file that contains information for separate software and license daemons.
Some system administrators prefer to consolidate license files for administrative purposes. The advantages to having one license file include centralized administration, one license file to track, and licensing environment variables with smaller values. The disadvantages include conflicting versions and bringing down the license server brings down all vendor daemons and licenses.
The following section describes how to merge license files. File Requirements for Merging License Files In order to merge license files successfully, the server host IDs for all of the licenses must match exactly. Therefore, you can consolidate the licenses from these two files into one file. All of the licenses that are going to be placed in one license file must have been generated using the same server host ID. Select one license file to start. Copy the entire contents of the file and paste into a text editor.
Open the second license file. Save the license file in text format. Stop and restart the license server to bring up and read the combined license file. The merged license file should be ready for use with your license server. For more troubleshooting tips, you can also refer to the License Administration Guide.
Common Troubleshooting Tips You should verify the following three areas when troubleshooting licensing: 1. License availability 2. Status report 3. Environment Variables 4. This utility allows you to attempt to check out and check back in a specified license, and reports any problems.
Optionally, type the Version number of the application you are trying to verify in the Version edit box. Click Apply. Many licensing failures are due to invalid or incorrect license environment configuration. This status report provides the same information as lmstat -a on UNIX. This utility displays server, daemon, and product usage. For the licensed application to access the required licenses, the licenses must either be available locally or from a license server.
Environment Variables Verify variables are set to the correct values. If you have other problems starting an application or with the server workstation, Table contains troubleshooting suggestions.
Troubleshooting Licensing Problem mgcld returns a message telling you the server has the wrong host ID when attempting to start the license server. Probable Cause Solution 1. You are running the license Verify the host ID with server on the wrong machine.
If the host ID does not match, 2. The host ID has changed. For contact 3. The host ID in the license information, refer to file was modified. There is no executable at on startup.
The executable does not have execute permission. The executable is for a different machine architecture. Use the chmod command to set execute and read permissions. Ensure you have the proper version of mgcld for your architecture.
You can run only one daemon. Troubleshooting Licensing cont. Probable Cause 1. The wrong license file is being referenced by the application. The server is down. Solution Verify the application is using the correct license file.
If system. The network is down. The license file was modified. Check the network using standard network commands. Restore the license file from a backup or reinstall the encoded license you received from Mentor Graphics. Call Mentor Graphics. License data corrupted in transmission.
Probable Cause The license server has exceeded the number of file descriptors available to its operating system. Solution There are two possible solutions to this problem: 1. Increase the number of file descriptors available to the operating system. Reduce the number of servers listed in the descriptors. If several users are simultaneously attempting to heavily dependent upon the obtain licenses, and each user network configuration and the is connecting to multiple file number of simultaneous users.
Raise the file descriptor limit The default limit in some operating system shells is 64 in the invoking shell to allow file descriptors. Programs that all licenses to be acquired. Application hangs when file descriptor limit reached. Problem Probable Cause Solution 1. If the license sever is hanging, reboot the license server.
Determine whether or not the license daemon is running. If not, restart the daemon. If the client machine is hanging, reboot the client machine. Ensure the license daemon is running on the server when the client reboots. Contacting Mentor Graphics Support If you have verified the previous areas and still need help solving your licensing problem, login to SupportNet Knowledgebase. For phone support in other locations, contact your local sales office or distributor.
Note Mentor Graphics currently does not support lmadmin. Use the commands listed in this Appendix to manage your license server and disregard the lmadmin documentation in the License Administration Guide.
An italic font is also used to indicate a pathname, manual name, or highlighted comment. Bold standard text within a paragraph indicates commands or options you type. Monospaced italic text in a shell command should be replaced with user-supplied values. Monospaced bold text indicates user input in an example command.

The pound symbol indicates a UNIX super-user or root shell. Shuts down selected license daemons both lmgrd and selected vendor daemons on all machines. Caution You should protect the use of lmdown, since shutting down the servers causes users to lose their licenses. Requires v6. Shuts down all servers if multiple servers are specified. Restricts lmdown to run only from the machine where the license server is running, if licenses are borrowed.
All licenses that were given out by those daemons are rescinded, so the next time a client program attempts to verify a license, the license is not valid. It does this with a one-minute delay before the servers shut down. To shut down only one of a set of redundant servers, you must kill both the lmgrd and vendor daemon processes on that license server machine. All rights reserved. Starts a license server. This option uses the letter l. Restricts usage of lmdown, lmreread, and lmremove to a FLEXnet Licensing administrator who is root by default.
If there is a UNIX group called lmadmin, then use is restricted to only members of that group. If root is not a member of this group, then root does not have permission to use any of the above utilities. Using this option prevents a Windows user from shutting down the license server with lmdown.
Disables the lmdown command no user can run lmdown. On UNIX, ensure the kill command does not have a -9 argument. Disables the lmremove command no user can run lmremove. Runs lmgrd in the foreground. If the -l argument is not used, separate windows are used for lmgrd and each vendor daemon. Displays usage information and exits.
Command Usage lmhostid [-n] [type] [-utf8] Options lmhostid Table A Header text is suppressed. One of the following hostid types. If not specified, the default hostid for the current platform is displayed. This is applicable only for those platforms that support FLEXid dongles. On Windows, it is the system name or, in the case of a terminal server environment, the terminal server client name.
To view a correct representation of the resulting hostid, use a utility, such as Notepad, that can display UTF-8 encoded strings. Description lmhostid displays the hostid of a system. Note Mentor Graphics recommends you not use lmreread and instead restart the license server if you have replaced the license file or made changes to the options file. Only this one vendor daemon should reread the license file. Instructs all lmgrds to re-read if more than one lmgrd is specified.
Description lmreread allows the system manager to tell the license daemon to reread the license file. Use this if the data in the license file has changed, so the new data can be loaded into the license daemon without shutting it down and restarting it. The license daemon always rereads the original file it loaded.
If you need to change the path to the license file, you must shut down the daemon and restart it with the new license file path. You cannot use lmreread if the server node name or port numbers have been changed in the license file. In this case, you must shut down the daemon and restart it for those changes to take effect.
If the optional vendor daemon name is specified, only the named daemon re-reads the license file and its end-user options file. Uses the specified license file s. Lists all users of the specified feature. This limits the amount of time lmstat spends attempting to connect to server.
Note that lmstat -a generates a lot of network activity. Do not display results. Requests a license with specified product date yyyy. The Server Status tab displays a listing of each feature found in a specified license file or server.
If the license server you reference is online, detailed information about each feature line served by the server displays. If the feature your application requested is not listed, then your licenses are not available on that server. The Server Diagnostics tab prints specific information on each license found in the file s and server s listed in your path. If a license is not available for checkout, the software displays an error message explaining why.
In this dialog box, specify a license feature name and press the Perform Diagnostics button to print specific information on that license. Reread allows the system manager to tell the license daemon to reread the license file. In this mode, you cannot start the lmgrd process, but you can do everything else. To configure this mode, do the following: a.
Click the Configuration using License File button. Type one or more the license file names or [email protected] specifications. For details on configuration using services, see the License Administration Guide.
Allows access to software updates for existing licensed software released prior to a support contract expiration date. Features are either composite, station, or atomic licenses and can be node-locked or floating. Provides a unique hostid for the licensing system Windows only. Ties licenses to a specified server or workstation. If an independent server is off the network, then all licenses associated with the server are unavailable. Mentor Graphics licensing includes two daemons, lmgrd license daemon and mgcld vendor daemon.
