License Manager problems in ANSYS Hello Venkat, I'll attempt to see if I can answer your question: The first thing I'd like to point out is that ANSYS actually uses Elan licensing for ANSYS 5.4, 5.5, and 5.6, *not* FlexLM. ANSYS used to use FlexLM in revision 5.3, I believe, but 5.4 through 5.6 are FlexLM. I'm assuming you're using 5.4 and above? (The reason why I ask is that the following commands are Elan commands, not FlexLM commands) There are several things you can do to "kill" or release a license, even without system administrative priviledges. 1) On UNIX, you can create a "wheel" group to give users administrative priviledges for ANSYS licensing *without* giving a user "regular" administrative rights. The "wheel" group is used by Elan licensing and does not provide a user with regular system administrative rights on the workstation. You sys admin shouldn't have to worry about creating this group as a result. This allows a regular user in the "wheel" group to kill a specific client(s). Please see the ANSYS Installation and Configuration Guide, Appendix A, for more details about the wheel group and how to create one (basically, it is modifying the /etc/group file to create this group). 2) A user should be able to kill his/her own client from the server without special administrative rights (as mentioned above). For the command-based method, use the "elmadmin" command. It is located as follows: UNIX: /ansys55/licutil//elmadmin Windows: C:ansys55licutilintelelmadmin where is your UNIX platform (e.g., "usparc", "sgi32", etc.). You can add the above directory to your PATH (in UNIX and Windows), so you don't have to type it the full pathname all the time. To list the clients, type: elmadmin -l This will list clients with client ID (CID). Find that CID and then type: elmadmin -b # where # is the CID from above. 3) You can perform the same tasks as point (2) above with a GUI-based administrative utility (instead of a command-based utility). To do so: UNIX: /ansys55/licutil//xelmadmin Windows: C:ansys55licutilintelwlmcntrl This is more user-friendly since it is GUI-based. Please see the ANSYS Installation and Configuration Guide on more details on how to use these utilities (it's not hard to use, but it takes a bit longer to explain than the command-based method, so please refer to this document for the various options). I hope the above helps. Points (2) and (3) shouldn't require administrative rights. Also, if you're familiar w/ UNIX commands, you can probably create a simple csh script which will kill your own license on your workstation (license server) to automate this process. There's a few other ways to "release/kill" your license after an abort, but the above may suffice as a first step. Best regards, Sheldon CSI ----- Original Message ----- To: xansys@o... Sent: Tuesday, December 21, 1999 8:41 PM Hello All, Typically we are installing ANSYS on Individual machines making each machine a license server. This we are doing so because if multiple licenses are loaded on a single machine and it serves as a server, in case of system break down nobody could use ANSYS. Hence My colleagues and my self find lot of problems with the Flexlm license manager ANSYS is currently using. When the ANSYS run gets aborted the license does not become free. When you try to invoke the license manager it says you shall not be able to restart the license manager since you re not administrator. you got to try many times to get ANSYS invoked. Most of the times ANSYS says no licenses available and aborts the session. Pro/Engineer by PTC uses a similar license manager. But they use a tool called Pro/Flush. When a run gets aborted, one can run this application which frees all the unused and frozen lines. May be ANSYS INC. also should think in those lines and facilitate users to come out of this embarrassing situation.
