License key file

License key definitions are stored in a text file called the license key file.

The license key file is created based on the data that you provided in IBM Rational® License Key Center. The license file can contain license key data for several products and is created for a specific host. License Key Administrator (LKAD) installs the license key file.

The license key definition contains information about the server nodes and vendor daemons, and at least one line of data (called FEATURE or INCREMENT lines) for each licensed product. Each FEATURE line contains a license key based on the data in that line, the host ids specified in the SERVER lines, and other vendor-specific data.

When users start an IBM Rational product, the environment variable LM_LICENSE_FILE is automatically defined for them. License manager uses this variable to locate the license file.
