Ellison looked back on the history between the two companies at the analyst meeting in September.

"I got kind of got cute commenting about Amazon uses Oracle, doesn't use AWS, blah, blah," he said. "And that hurt some people's feelings. I probably shouldn't have said it."

He said a friend at a major New York bank had asked him to make sure the Oracle database works on AWS.

"I said, 'Great. It makes sense to me,'" Ellison said.

The multi-cloud strategy should deliver gains in database market share, said analyst Siti Panigrahi of Mizuho, which has the equivalent of a buy rating on Oracle shares. Cloud deals related to AI will also help Oracle deliver on its promise for faster revenue growth, he said.
