Enterprise grid computing aims to consolidate IT resources - including both infrastructure software and applications - and optimize their usage, cutting costs substantially along the way. Since Java and J2EE are widely used as enterprise software platforms, how do they align with this vision? This article outlines a set of challenges that JDBC faces as the database connectivity layer within enterprise grid environments and illustrates how the Oracle Database 10g JDBC driver addresses these challenges. First, I'll introduce the concept of enterprise grid computing; then I'll examine how Java and J2EE operate in grid environments and identify their database co... (more)
