Oracle suffered a blow when the Pentagon axed the database giant from bidding for JEDI, the massive Department of Defense cloud contract, worth up to $10 billion. Catz and Oracle have persistently challenged the DOD’s bidding process, filing appeals ­intended to put the company back in the running. In September, Catz’s purview expanded internally when her co-CEO, Mark Hurd, took a medical leave of absence.
