Technote (FAQ)


Question

How do you change IBM Rational ClearCase clients and license server configuration between Atria and FLEXlm licensing On UNIX and Linux?

Answer

Switching from Atria licensing to FLEXlm licensing:
To switch from Atria licensing to FLEXlm licensing, follow these steps.

  1. Identify the name of the FLEXlm license server host

  2. On the client machine, stop ClearCase

  3. Copy the flexlm_host.template file (located in one of the following directories) to the /var/adm/rational/clearcase/config directory
    • /opt/rational/clearcase/config/rcl/flexlm_host.template
      or
    • /opt/IBM/rational/clearcase/config/rcl/flexlm_host.template
      or
    • /opt/IBM/RationalSDLC/clearcase/config/rcl/flexlm_host.template

  4. Rename the flexlm_host.template file to flexlm_host

  5. Verify that this file has read access for all users

  6. Open the flexlm_host file and replace the word hostname with the name of the FLEXlm license server host

    Example:
    SERVER hostname ANY <port optional>
    USE_SERVER  


  7. If you still have another copy of the flexlm_host or license_host file, delete it to avoid confusion

  8. Restart ClearCase service. The license should be checked out from the specific FLEXlm license server.
