License manager commands

System administration commands and daemons used by License Manager.
IBM Rational Common Licensing uses the License Manager from Acresso Corporation. The License Manager includes the following components:
  • A vendor daemon named rational or ibmratl that dispenses IBM Rational® licenses. The rational daemon is used for most IBM Rational licensed products. The ibmratl daemon is used for licensed IBM Rational products built on the Eclipse framework. If you have other products from other vendors that also use FLEXlm software, they will include their own vendor daemons.
  • A license daemon named lmgrd. The lmgrd daemon does not process requests on its own, but forwards requests to the appropriate vendor daemon.
  • A license file that you maintain. The license file specifies your license servers, vendor daemons, and product licenses.
Note: Use a single combined license file for all Rational products.

To verify that your license manager is operational, you can enter these commands on your UNIX® system license server to see if its daemons are started:

% ps axw | grep -v grep | egrep “lmgrd|vendor"

or

% ps -e | grep -v grep | egrep “lmgrd|vendor"

Where vendor is rational or ibmratl.

The output should include lines similar to the following (your path names may vary):

538 ?? S 0:03.50 /rational/base/cots/flexlm.7.0f/platform/lmgrd

-c /rational/config/servername.dat

-l /rational/config/servername.log

539 ?? I 0:00.90 rational -T brazil 6.0 3 -c ...
