ClearCase Support: Configuring ClearCase License Server
Each ClearCase server and client must be configured to know which computer is the ClearCase License Server. Here is the text file that each computer with ClearCase installed on it needs to have defined.
|$ cat /usr/adm/atria/config/license_host
The SERVER_NAME must be the License Server's name, such as "license.server.com" or a local alias to the license server. An alias is advisable to minimize down times.
