Configure your Rational license server by specifying license server elements.
27000@myserver
You must enter multiple license servers in port@host format using a semicolon as the separator. For example:
@license1;27000@license2;27000@server2
If no port is specified, the default port is used.
For information about setting up redundant server triads and information pertaining to licensing, see the IBM Rational License Management Guide.
