Tired of being a punching bag, Oracle Corp. is hitting back at the State of Oregon over claims that the software company and the contractors it provided were responsible for the failure of the state's health insurance exchange to produce a functioning self-service website. According to the lawsuit filed Friday, the state has been using a smear campaign to deflect attention from its own project management failures -- particularly constantly changing, never-finalized requirements that sabotaged the software development process. In addition to suing for unpaid consulting and licensing fees, Oracle used the filing to defend its reputation.
