RESEARCH TRIANGLE PARK – Oracle CEO Mark Hurd has died. He was 62.

The company on Friday confirmed his death. Hurd was on medical leave, and the company did not disclose a cause of death.

Oracle has a major presence in the Triangle with offices in Morrisville and Durham.

Hurd led two high-profile Silicon Valley companies — Oracle and computer maker Hewlett-Packard.

He took a leave of absence from Oracle a month ago for health reasons. Larry Ellison, Oracle’s founder and chairman, said at the time that he and co-CEO Safra Catz would take over his responsibilities.

Ellison says he will miss his close and irreplaceable friend.

“Mark was my close and irreplaceable friend, and trusted colleague,” Ellison said in a memo to Oracle employees that was posted on Mark Hurd’s personal website. “Oracle has lost a brilliant and beloved leader who personally touched the lives of so many of us during his decade at Oracle. All of us will miss Mark’s keen mind and rare ability to analyze, simplify and solve problems quickly.”

When Hurd began the leave of absence, he said in a message to employees: “I’ve decided that I need to spend time focused on my health.”

His LinkedIn page notes of his Oracle career:

“As CEO of Oracle, Mark has helped shift the long-term strategy of the company toward the cloud. Offering a unique blend of on-premise, cloud, and hybrid cloud deployment solutions, Oracle’s cloud portfolio brings flexibility and security–reducing cost and increasing efficiency. Mark called out an industry-wide transition to the cloud in his 2014 Oracle OpenWorld keynote address, predicting that 80% of corporate data centers would be gone by 2025. Adapting to this new business model and staying ahead of the curve have been top priorities.”
