In a meeting with Oracle President Safra Catz in Brussels on Wednesday, Competition Commissioner Neelie Kroes "expressed her disappointment that Oracle had failed to produce, despite repeated requests, either hard evidence that there were no competition problems or, alternatively, proposals for a remedy to the competition problems identified by the Commission," a Commission spokesman said.

Kroes said the Commission was willing to move quickly towards a final decision but "underlined that a solution lies in the hands of Oracle," according to the spokesman.

An Oracle spokeswoman said the company declined to comment.

Oracle's proposed US$7.4 billion Sun acquisition was by U.S. regulators in August, but two weeks later the Commission announced it would launch an of the deal, citing "serious concerns" about its effects on competition in the database market.

The Commission said it was concerned about Oracle, the world's top seller of database software, taking ownership of MySQL, the leading open-source database, which Sun acquired last year.
