Introducing IBM® DB2® 10 for z/OS
In today's business and economic environment, the challenge for IT is clear: improve operational efficiencies, reduce costs, and adapt quickly to support business growth -- all without sacrificing the resiliency required for today's demanding business requirements. DB2 for z/OS continues to be the undisputed leader in total system availability, scalability, security, and reliability at the lowest cost per transaction. DB2 10 for z/OS continues to build on these formidable capabilities of DB2 9 for z/OS, and delivers innovations in these key areas:

Improved operational efficiency for "out-of-the-box" DB2 CPU savings
DB2 10 delivers great value by reducing CPU usage. IBM's internal testing and early beta customer results revealed that, depending on the specific workload, customers could achieve out-of-the-box DB2 CPU savings of up to 5% - 10% for traditional workloads and up to 20% for specific workloads; when compared to running the same workloads on DB2 9. DB2 reduces its CPU usage by optimizing processor times and memory access, leveraging the latest processor improvements, larger amounts of memory, and z/OS enhancements. Improved scalability and virtual storage constraint relief can add to the savings. Continued productivity improvements for database and systems administrators can drive even more savings.

Unsurpassed resiliency for business-critical information
Business resiliency is a key component of the value proposition of DB2 for z/OS and the System z platform. Uniquely integrated technology allows DB2 for z/OS and System z to support your efforts of keeping your business running even when things go wrong or you need to make changes. DB2 10 innovations raise the bar on data resiliency through scalability improvements and fewer outages. This release delivers the ability to support up to five to ten times more concurrent active users in a single DB2 subsystem than in DB2 9, allowing customers to scale-up or scale-out simply, and with less system management. Schema evolution or data definition on demand as well as query performance manageability enhancements support improved availability and performance manageability.

Rapid application and warehouse deployment for business growth
Staying competitive in today's global economy is tougher than ever, requiring agility, adaptability, and responsiveness. SQL and pureXML enhancements in DB2 10 help extend usability, improve performance, and ease application portability to DB2 for z/OS, supporting your efforts to create an efficient, productive application structure with a sustainable competitive advantage.
DB2 10 adds unique temporal capabilities to support business and system time within the database itself, making application development and maintenance significantly simpler and more cost effective.
