Trends Industry signals to keep you in the know What’s Ahead? DB2 X leads the industry to minimize complexity and maximize productivity BY TERRIE JACOPI AND JEFF JOSTEN I n today’s business and economic environment, the challenge for IT is clear: improve responsiveness, reduce costs and boost productivity. Building on the formidable capabilities of DB2* 9 and the System z* platform, the next release of DB2 meets these challenges head on. DB2 X delivers unique capabilities to drive your competitive advantage. Exper ience signif icant performance improvements, along with scalability and availability levels that continue to outpace the industry. These improvements are delivered along with core capabilities that minimize complexity, maximize resource productivity, and reduce CPU and resource costs. same workload, with no application or significant administration changes, you’ll require fewer MIPS and resources. SQL performance improvements include: more aggressive pushdown of predicate evaluation; more efficient processing of OR and IN predicates; and better use of work files to avoid fallback to table space scans for large quer ies. Leveraging new database design capabilities—such as in-line large objects (LOBs) and hash access—can bring additional performance improvements and cost savings. Core performance goals include a 5- to 10-percent improvement for traditional transaction workloads and up to a 20-percent improvement for newer, nontraditional workloads like those that use SQL Stored Procedures. Individual SQL statements may see larger improvements. DB2 X will bring cost savings across all types of workloads. The improved transaction times and lower CPU usage can allow you to be more efficient and effective, deliver more with your current investment and free up capacity for new workload requirements. Even More Scalability DB2 and the System z platform continue to lead the industr y with unique, integrated scalabilit y capabilities. The industr y-proven data-sharing capabilities, architected together with z/OS* and System z Parallel Sysplex*, provide efficient, linear scalability that solutions on other platforms can’t match. In addition, the capability to scale horizontally is a proven, effective way to efficiently support extreme scaling requirements for large workloads. Single-member limits are being pushed as the data explosion on the System z platform continues. DB2 X addresses vertical growth by allowing substantially more threads per DB2 image (data-sharing member or non-data-sharing subsystem). Compared to DB2 9, Performance Improvements As customers move from DB2 V8 to DB2 9 Conversion Mode (CM), they generally find CPU improvements, particularly in the utilities. Most see CPU reductions of around 20 percent. Picking up where DB2 9 left off, IBM is focusing on “out-of-the-box” CPU processingtime improvements for all workload types including transactions, queries and batch.
