This section addresses questions that relate to the operation of the license server. The answers to these questions usually involve running one of the licensing administration tools.
To update a license file, you should terminate your license server, replace the old license file with the new license file, and restart the license server. If necessary, you can also update the license file without stopping the license server so that there will be no interruption to Abaqus users. Both techniques are described in detail in “Updating an Abaqus license file,” Section 3.2.
The easiest way to see if a license server is running is to execute the command
abaqus licensing lmstatThis command will list the license servers that are running for a general broadcast. To see if a license server is running on a specific computer, you can enter the command
abaqus licensing lmstat -c [port]@license_server_hostwhere license_server_host is the hostname of the license server that you want to query. If the license server is using a port that is not between 27000 and 27009, you must specify the port number as well.
You must login on the license server host to restart the server (on Windows platforms you must login as Administrator) and then run the lmgrd program (see “FLEXnet license server manager lmgrd,” Section 3.5). For an alternate method, see “Starting the server using LMTOOLS,” Section 3.6.9.
You use the FLEXnet Licensing administration tool lmdown to terminate an Abaqus license server. If you use lmdown to terminate a license server that is part of a redundant license server configuration, all three license servers in the redundant configuration will be terminated. If you do not want to terminate all three servers, you must use an operating system utility, such as the ps and kill commands (UNIX platforms) or the Windows Task Manager, to terminate the license server. Do not use the -9 option when using the kill command. For more information, see “lmdown,” Section 3.6.2.
The client enters a state of “suspended animation.” The client will attempt to reestablish contact with the license server until a user-defined expiration time is exceeded (the default is to continue checking perpetually until contact is reestablished). The minimum expiration time is 60 minutes. If the predefined expiration time has not been set, the client may be terminated by using the standard kill command (UNIX platforms) for the process. On Windows platforms the client can be terminated by entering <Ctrl>-C in the DOS window where the client was started if the job was run in interactive mode; otherwise, use the Task Manager.
Tokens are normally returned immediately. If the tokens are not returned immediately, ensure that the job is not running and stop the executable for the analysis by using abaqus terminate or the appropriate operating system utility, such as the ps and kill commands (UNIX platforms) or the Windows Task Manager.
Do not use the lmremove tool to free license tokens used for analysis jobs, as it will not have the intended effect. You can use lmremove to free Abaqus/CAE or Abaqus/Viewer license tokens; you must first obtain token information using the lmstat tool (for an example, see “lmstat,” Section 3.6.7).
No, only log file information is available. When an analysis job is in the license queue, information about the queue status is written to the log or status file for the job every 30 seconds. Abaqus/CAE and Abaqus/Viewer interactive sessions are not queued.
The command simulia_dir/License/lmstat -a, where simulia_dir is the SIMULIA parent directory, will list users and the license features that they are using. For more information, see “lmstat,” Section 3.6.7.
Yes, you must obtain new license keys from your local office or representative when you upgrade to a new general release of Abaqus (for example, from Abaqus 6.10-3 to Abaqus 6.11-1). The new license keys will run previous releases of Abaqus that used FLEXlm or FLEXnet Licensing. Maintenance deliveries do not require new license keys within the same general release. For example, a license key obtained for use with Abaqus 6.11-2 will work with later maintenance deliveries (such as Abaqus 6.11-3, Abaqus 6.11-4, etc.) and previous releases (Abaqus 6.10-1). This license key will not work with Abaqus 6.12-1 or later.
Yes, if the new release of Abaqus uses a later version of FLEXnet Licensing than your existing license server. Abaqus 6.11 uses FLEXnet Licensing Version 10.8.7. If you have a version of FLEXnet Licensing earlier than Version 10.8.7 installed on your system, you should use the licensing installer to automatically upgrade the license server. If you have an existing license server that uses a version of FLEXnet Licensing higher than Version 10.8.7, you should use the procedure described in “Updating an Abaqus license file,” Section 3.2, to update your license file without overwriting the existing license server. For more information, see “Licensing installation,” Section 2.1.2. If your Abaqus license file is integrated with FLEXnet license files for other products using a combined license file, you must ensure that the lmgrd version meets the FLEXnet version compatibility rules (listed in Appendix I of the FLEXnet Licensing End User Guide Version 10.8).
You can check under Licensing on the Support page at www.simulia.com for the FLEXnet Licensing End User Guide or to see if a maintenance delivery includes a later version of FLEXnet Licensing.
