SAN FRANCISCO — Oracle America Inc. on Wednesday was sued by the Department of Labor for allegedly favoring people of Indian descent in hiring while paying white men more than women and minorities, making it the third major Silicon Valley company to land in the labor enforcer’s crosshairs in less than a year.

Oracle, represented by Orrick, Herrington & Sutcliffe senior counsel Gary Sinsicalco, is also accused of failing to turn over compensation and hiring data in violation of rules that apply to federal government contractors. The Labor Department complaint seeks to cancel Oracle’s millions of dollars in existing contracts and debarment to preclude it from participating in future bids.
