IBM Cognos Data Manager support is ending on 30th September 2015. Since June 2014, customers with valid support contracts have been provided licenses for IBM InfoSphere DataStage. The new licenses are not simply for IBM InfoSphere DataStage but will also allow continued usage of IBM Cognos Data Manager.
