Book Description
This IBM® Redbooks® publication discusses in detail the facilities of DB2® for z/OS®, which allow complete monitoring of a DB2 environment. It focuses on the use of the DB2 instrumentation facility component (IFC) to provide monitoring of DB2 data and events and includes suggestions for related tuning. We discuss the collection of statistics for the verification of performance of the various components of the DB2 system and accounting for tracking the behavior of the applications. We have intentionally omitted considerations for query optimization; they are worth a separate document. Use this book to activate the right traces to help you monitor the performance of your DB2 system and to tune the various aspects of subsystem and application performance.

Book Description
IBM® DB2® buffer pools are still a key resource for ensuring good performance. This has become increasingly important as the difference between processor speed and disk response time for a random access I/O widens in each new generation of processor. An IBM System z® processor can be configured with large amounts of storage, which if used wisely, can help compensate by using storage to avoid synchronous I/O. Several changes in buffer pool management have been provided by DB2 10 and DB2 11. The purpose of this IBM RedpaperTM is to cover the following topics: Describe the functions of the DB2 11 buffer pools Introduce a number of matrixes for read and write performance of a buffer pool Provide information about how to set up and monitor the DB2 buffer pools The paper is intended to be read by DB2 system administrators, but it might be of interest to any IBM z/OS® performance specialist. It is assumed that the reader is familiar with DB2 and performance tuning. In this paper, we also assume that you are familiar with DB2 11 for z/OS performance. See DB2 11 for z/OS Technical Overview, SG24-8180; and DB2 11 for z/OS Performance Topics, SG24-8222, for more information about DB2 11 functions and their performance.

Book Description
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.

Book Description
This IBM® Redbooks® publication is intended to make System Programmers, Operators, and Availability Managers aware of the enhancements to recent releases of IBM z/OS® and its major subsystems in the area of planned outage avoidance. It is a follow-on to, rather than a replacement for, z/OS Planned Outage Avoidance Checklist, SG24-7328. Its primary objective is to bring together in one place information that is already available, but widely dispersed. It also presents a different perspective on planned outage avoidance. Most businesses care about application availability rather than the availability of a specific system. Also, a planned outage is not necessarily a bad thing, if it does not affect application availability. In fact, running for too long without an IPL or subsystem restart might have a negative impact on application availability because it impacts your ability to apply preventive service. Therefore, this book places more focus on decoupling the ability to make changes and updates to your system from IPLing or restarting your systems.

Book Description
IBM DB2 11 for z/OS focuses on CPU savings and performance improvement through innovations within DB2 and the synergy with IBM 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 Data Definition Language (DDL) updates. This IBM Redbooks publication provides the details of the performance of DB2 11 for z/OS, discussing the possible performance impacts of the most important functions when migrating from DB2 10. It includes performance measurements made in the Silicon Valley Laboratory and provide considerations and high-level estimates. It assumes familiarity with DB2 11 for z/OS. --
