Essential information about early customer experiences, migration advice, and performance specifics from IBM experts directly involved in the development of DB2 11
 
Building on the previously published DB2 11: The Database for Big Data and Analytics, this book is particularly for new and existing DB2 for z/OS customers and users who want to learn as much as they can about the new software version before migrating their organizations to DB2 11 for z/OS. The guide begins with a technical overview of DB2 11 features and explains how the new functions in DB2 11 can help enterprise customers address the challenges they face with the explosion of data and information. There has been rapid growth in the variety, volume, and velocity of data due to the increase of smart devices, mobile applications, cloud computing, and social media, and many of the enhancements in DB2 11 are focused on enabling enterprise customers to respond to these market opportunities in a cost-effective way. The book includes a detailed discussion for helping customers plan their DB2 11 migration strategy, and shares experiences of people who have already upgraded to DB2 11 and participated in IBM's Early Support Program. A third section of the book addresses one of the most common obstacles that prevents customers from migrating to a new release: the need to implement any code changes required due to application incompatibilities. With DB2 11's "application compatibility" support, such applications can continue to run under the new release until those changes can be implemented, removing them as an upgrade dependency.
