Since its initial inception in DB2® for z/OS®, the cost-based Optimizer has continually evolved to deliver expert-based query and workload analysis and many other performance-enhancing functions. Based on the latest use by customers, the Optimizer delivers even more in DB2 10. This session will show you how the Optimizer in DB2 10 for z/OS can help reduce your total cost of ownership. We’ll discuss incremental query optimization enhancements available with the upcoming release of DB2 10 that build on DB2 9 enhancements, such as global query optimization.
