SAN FRANCISCO (AP) — Oracle CEO Larry Ellison says the business software maker is helping the Obama administration fix the technological problems that have been preventing people from signing up for government-mandated health insurance.

Ellison told shareholders at Oracle's annual meeting Thursday that the company is pitching in with other government contractors in an effort to make Healthcare.gov more reliable and secure. He didn't say how many Oracle engineers are addressing the issues that have crippled the website during its first month of operation.

Frustrations with the troubled website have been compounded by concerns that it lacks the security measures need to protect the personal information of people looking for insurance.

The U.S. government has long been one of Oracle Corp.'s biggest customers.
