Informix Fires CEO

Informix Corp., a maker of database software, fired Chief Executive Jean-Yves Dexmier, replacing him with board member Peter Gyenes just a little more than a week after Informix surprised investors with a weaker-than-expected second quarter. Gyenes, 54, becomes chief executive immediately, replacing Dexmier, 48, who held the position since July 1999. Informix, based in Menlo Park, Calif., plans to report second-quarter earnings July 19.
