You would like to know how to use the network license time-out feature.
The Network License Manager can be configured to reclaim a license when a client workstation is idle for longer than a defined time-out period*, or the connection with the workstation is lost.
*This option is not applicable to AutoCAD 2002 based products.
Any of the following activity in the active application prevents the client workstation from being idle:
Any mouse click.
Any command, Lisp expression, menu macro or script in progress.
Any Modal dialog box opened (a dialog box which needs to close before continuing to other tasks).
Note: Using the Help system does not keep the session active.
Configuring License Time-out
License time-out is configured by implementing an options file with the Network License Manager. For a detailed explanation of options files, please refer to theFLEXlm End User Guide, located by default on the network license server in the following directory:
A brief explanation of options files is provided below:
Options files are created with an ASCII text editor, such as Microsoft Notepad.
Keyword statements are used in an options file to configure various operating parameters of the Network License Manager.
The options file must be named adskflex.opt.
The options file must be located in the same folder as the Autodesk product license file.
All text in an options file is case sensitive.
The options file is read each time the license manager is started or the license file is reread.
License time-out is configured in an options file by using the TIMEOUT keyword.
The syntax is: TIMEOUT [feature] [n], where:
[feature] specifies the application you want to control. The feature code can be found in the license file, right after the word INCREMENT.
[n] is the number of seconds before the license server reclaims an inactive license. The minimum value is 900.
Example: TIMEOUT 48800ACD_2006_0F 3600
This line in an options file would configure the Network License Manager to reclaim an AutoCAD 2006 license (feature code 48800ACD_2006_0F), if the client machine was idle for 3600 seconds (one hour).
License Time-out Behavior
If your license is lost because of the idle time-out, the product attempts to claim a new license once you access the product again. If a license is available, the client pulls a new license and continues the session. If no license is available, you will be prompted to save your work before the product shuts down.
Note: The debug log file can be examined to determine if a license has been reclaimed. When a license has been reclaimed, the debug log file will contain a line similar to:
