B05 - DB2 11 for z/OS Performance Topics

Topic: 2015 EMEA

Subtopic: DB2 for z/OS

DB2 10 for z/OS provided a strong performance improvement that drove great value for IBM clients. DB2 11 for z/OS continues the trend by focusing on further CPU savings and performance improvement through innovations within DB2 and the synergy with System z hardware and software. Most of CPU reductions are built-in directly to DB2, requiring no application changes. Enhancements often take effect after the rebind in the case of static applications, while some enhancements require user actions such as DDL updates. DB2 11 CPU reduction can potentially provide significant total cost of ownership savings depending on the application mixture and type of transactions. In this session we will discuss some of the changes that are documented more fully in the IBM redbook SG24-8222 (by the same title), including IBM internal measurement results of DB2 11.
