Former MySQL CEO Marten Mickos is leaving Sun Microsystems. He is the third senior MySQL executive to leave since Sun's acquisition of the open source database company.
Mickos became senior vice-president of Sun's database group after last year's acquisition.
MySQL creator Michael "Monty" Widenius said in a blog last week that he was leaving. His departure came after dissatisfaction over the way he said Sun was managing MySQL development.
MySQL co-founder David Axmark left the firm last year. Mickos has been replaced by Sun executive Karen Tegan Padir.
Padir is now vice-president of the new MySQL and Software Infrastructure Group, which includes identity management, service oriented architecture (SOA), and Java enterprise development.
Sun said MySQL development will now be more closely integrated with its other technologies.
