Analysts have expressed surprise at the sudden resignation of Ray Lane, president and COO of Oracle saying this will increase pressure on the company in Wall Street.
Merrill Lynch analyst Chris Shilakes said: "This could place near-term pressure on Oracle as Lane had held senior positions at Oracle for the past eight years and was highly regarded by Wall Street."
"I think Ray Lane was even more of a guiding force at Oracle than the general public gave him credit for. He will be sorely missed," said Mike Prince, CIO of Burlington Coat Factory. "He called a lot of the shots at Oracle."
Prince sat on a customer advisory board with Lane, and said Lane showed more empathy with customers than other Oracle execs have shown.
"While Lane and [Ellison] (chairman and CEO) had their differences in the past, we had not heard of any increased friction recently. So the departure comes as a surprise," Shilakes said.
However, there have long been open disagreements in business strategy between the No. 1 and No. 2 leaders at Oracle.
Last year, Lane told Computerworld he saw problems with Ellison's new business-unit accountability model, which forces each part of the organisation to be totally accountable for what it delivers, even though other departments may have a large impact on a particular product or service.
