Test Performance version 8.2 or later requires IBM® Rational® License Server version 8.1.1 or later. If you have used a previous
version of Test Performance with a license server, this error message can be displayed
when the IBM® Rational® License Key Administrator points
to an incompatible version of the license server. Ensure that the IBM® Rational® License Key Administrator has been
configured to point to the correct version of the license server.
Use Rational® License Key
Administrator version 8.1.1 or later. On Microsoft™ Windows™, Rational® License Key Administrator 8.1.1 is installed in the IBM® Rational® program group. For more information on licensing, see the Installing and upgrading section of the product documentation.
If the error message persists, specify the port on which the license
server is listening as the Port ID value. By
default, the Port ID on the license server
is 27000.
Test Performance comes with a compatible version of Rational® License Server. If you install
another version of Rational® License Server on the same computer, this error can occur. Use the
version of Rational® License
Server provided with Test Performance.
