IBM said Monday that it doesn't plan to open-source its DB2 database, despite a published report quoting a company executive in the U.K. saying that an open-source move might become necessary.

Chris Livesey, IBM's director of information management software in the UK, told a ZDNet UK reporter that changing conditions in the database market could eventually prompt the company to open-source its flagship database.

"We have a light version of the product offered for free, which is a step towards exposing our core technology," Livesey was quoted as saying in reference to the company's DB2 Express-C software. "Looking at IBM's heritage in contributing to the open-source market, we've been particularly keen to lead that market. . . . As the future unfolds, and the economics become clearer, there's going to be more commitment to open source by everybody. We've made good steps towards that."

Among large IT vendors, IBM is widely considered the strongest supporter of Linux and open-source technologies. It has open-sourced a number of products, such as its Cloudscape Java database, Eclipse application development framework and Lotus Symphony office suite. It has also created proprietary versions of popular open-source software, most notably those from the Apache Software Foundation.

But in an e-mail sent on Monday, an IBM spokeswoman wrote flatly: "IBM has no plans to open source DB2."
