DB2 UDB for z/OS Version 8 Performance Topics

IBM DATABASE 2 Universal Database Server for z/OS Version 8 (DB2 V8 throughout this IBM Redbook) is the twelfth and largest release of DB2 for MVS. It brings synergy with the zSeries hardware and exploits the z/OS 64-bit virtual addressing capabilities. DB2 V8 offers data support, application development, and query functionality enhancements for e-business, while building upon the traditional characteristics of availability, exceptional scalability, and performance for the enterprise of choice. Key improvements enhance scalability, application porting, security architecture, and continuous availability. Management for very large databases is made much easier, while 64-bit virtual storage support makes management simpler and improves scalability and availability. This new version breaks through many old limitations in the definition of DB2 objects, including SQL improvements, schema evolution, longer names for tables and columns, longer SQL statements, enhanced Java and Unicode support, enhanced utilities, and more log data sets. This redbook introduces the major performance and availability changes as well as the performance characteristics of many new functions. It helps you understand the performance implications of migrating to DB2 V8 with considerations based on laboratory measurements. It provides the type of information needed to start evaluating the performance impact of DB2 V8 and its capacity planning needs.
