Resolving the problem


  • Use one of the following types of license keys:
    • node locked ( IBM Rational DOORS AUTH USER LIC)
    • floating (IBM Rational DOORS FLOATING LIC)

  • If you do not have floating or node locked license keys for IBM Rational DOORS available, contact IBM Rational licensing support team for temporary license keys

You may open a New PMR via the SR tool:

The IBM Service Request application will have to be used instead.

As of October 1, 2014, IBM Rational no longer accepts PMR creation requests via email.

For EMEA the same will apply as of January 1, 2015

AP has the change-over planned for April 1, 2015

PLEASE NOTE: This change only affects our clients ability to submit new support requests via email to Rational Support .
Our clients will still be able to correspond with our Rational Support staff via the support email address once a PMR has been created,
The PMR number must be mentioned in the subject line of your email.

For an SR User to submit a new Licensing related support request in the IBM Service Request application he will need to deselect "Show entitled products only" and then enter as keyword "Rational license problem"
