Problem: Unable to Start the License Manager on a Multi-license Server

Scenario:

Suppose a multi-license IDL lmgrd server is moved to a different machine. Now for some reason the administrator is unable to get the license manager to start correctly. It appears to be conflicting with another software license even though they are going to different ports. The administrator decides to combine the license files so they have a single SERVER line, same hostname, and same hostid. The other software license is fine, however IDL gives the following (abbreviated) FLEXnet licensing error:

The desired vendor daemon is down.
FLEXnet Licensing error: -97,121

If the IDL and the other software have separate license files and separate lmgrds, the other software is fine but IDL reports the following when attempting to start the IDL lmgrd:

11:24:34 (lmgrd) ERROR: license files have conflicting port numbers
11:24:34 (lmgrd) 7100 and 1700
11:24:34 (lmgrd) Please edit the license files so the port numbers
11:24:34 (lmgrd) on the SERVER line are identical.
11:24:34 (lmgrd) License files include: /usr/local/othersoftware/license.dat; /usr/local/lib/idl/license/license.dat

Editing the port numbers in either license to match still causes errors...

The recommended solution, to starting and stopping the license manager in an environment that has multiple license servers running, is to use the '-c' switch for lmgrd to specify which license server you want to reference. For example, to start the license manager with respect to an Exelis Visual Information Solutions license file in the default location, issue the following command (as one line):

• /usr/local/itt(or exelis)/idl/idlxx/bin/lmgrd -c /usr/local/itt(or exelis)/license/license.dat
