A.5 Replacing Codes on an Existing Windows Server
Follow these steps if you have an existing Patran installation (version 7.0 or later) and have received new codes (as a renewal, change, etc.).
Edit The New License File
Place the new codes as a license file in the same directory as the existing license.dat file. Name it license_new.dat. Change the SERVER and DAEMON lines in the new license file to include the same port number, server name, and paths as the existing file. For example:
SERVER server1 123465 1700
DAEMON MSC /msc_licensing/flexlm/bin/msc
Replace License File
Use Windows Explorer to rename the existing license.dat file to license_old.dat, and the new file to the current license file name (i.e. license.dat).
Stop and Restart the FLEXlm Service
Using lmtools.exe,
1. Click ON CONFIGURATION USING SERVICES Radio Button.
2. Select appropriate license server in box below (if you have more than one).
3. Click ON START/STOP/REREAD Tab.
This should re-read the license.dat file and enable your new licenses. If there is a problem with this, or if the licenses still do not appear to be available, restart the system.
