Analytics are the hot business need because the competitive advantage goes to the organization who is first to discover and capitalize on the business insight. Data is at the root of this, but it is the analytics that provide data value. For many years DB2 has been used with OLAP and OLTP systems by SAP customers worldwide to deliver a cost-effective database engine to SAP applications.
Now with DB2 10.5 with BLU Acceleration, you can use this next generation in-memory technology to deliver these insights from data fast and simply. DB2 with BLU Acceleration is an in-memory technology, which makes analytical jobs by factors faster right out of the box, while requiring dramatically less storage and nearly eliminating the need for tuning.
Although BLU Acceleration is in-memory optimized, it is not main memory-limited. DB2 BLU is highly optimized for accessing data in RAM, but performance won’t suffer as data size grows beyond RAM. These benefits are achieved through next generation columnar processing, operating on compressed data, carefully exploiting modern microprocessor designs, and accessing memory efficiently. The result is a system that simultaneously looks and feels like DB2 while being in-memory optimized, CPU-optimized and I/O-optimized.
SAP-DB2 customers have seen tremendous performance improvements with the same hardware. Because of this, customers can reuse their existing IT infrastructure and simply update to the newer DB2 10.5 version-- converting row-store tables to column-store tables.
Join DB2 - SAP expert Guersad Kuecuek for a discussion of the technical features of this solution including how to use BLU, how to derive performance improvement and how to do the sizing for BLU.
Judy Ruby-Brown gives a thorough overview of system level backup and using FlashCopy for disaster recovery as provided by various vendors. This presentation is quite thorough but yet very easy to understand, even for a beginner. Judy explains the types of services that need to be setup for disaster recovery as well as easy scenarios for the DBA in the implementation of disaster recovery. Just the summary at the end is enough to pass on to the system programmers in your shop as a checklist for implementation.
Jef Treece and Shawn Moe, IBM Labs; with Rick Swagerman (host)
The "Internet of Things" is the growing number of devices and sensors that communicate via the Internet, offering vast new opportunities. Harnessing data from billions of connected devices lies in the ability to store, access and query SQL and NoSQL data together, seamlessly. The result of all this data is the need for fast development of web and mobile applications and speed-of-thought insight for fast business decisions.
Learn how to use Informix and DB2 to bridge the gap between new computing technologies designed for big data, cloud, and mobile computing with the enterprise world of relational data in the "Internet of Things" era. Jef Treece and Shawn Moe will present how to develop mobile applications using techniques that preserve the native look and feel specific to such devices as Android and iOS. They will also show device-agnostic techniques and discuss new approaches to handling a range of types of mobile devices. A discussion of how to keep data on the device in sync with a back-end database or cloud service, such as DB2 or Informix on BlueMix will also be included. And finally, using an embedded database to achieve a truly scalable and reliable Internet of Things architecture will be included.
In this comprehensive overview of DB2 10 for z/OS Lori Ann Galluzzo goes through the features of DB2 10 in great detail. Each feature is discussed, along with how and when to take advantage of the feature, as well as some pitfalls and things to watch out for.

Watch a demonstration of IBM Cognos Business Intelligence running on a DB2 BLU Acceleration in-memory database.
The demo compares, side-by-side, the performance of a dashboard sitting on top of a traditional row-based data warehouse with indexes, versus a dashboard sitting on top of the same database, with BLU Acceleration.
BLU Acceleration is an innovation from IBM Research and Development labs that delivers a new generation of In-memory database technology, for "speed of thought" analytics. Coupled with Cognos Dynamic Cubes, it results in sub-second query result times. See it for yourself!
SQL is a powerful language that you will learn to use to a greater extent in this talk! Join us to explore some of the less well-known features of SQL and see how they can help in some practical situations. We will also look at some common mistakes and misconceptions and discuss ways of avoiding them. Among the topics:
- tricks with date and time values
- use of common table expression and recursive queries
- use of data change tables
- use of nested tables
- use of the MERGE statement
- and more.
Nick Ivanov is presenting this talk based on his consulting experience with many customers to maximize use of IBM DB2 and other products; move applications to DB2; and tune database and query performance.
Although the DBA’s tuning efforts often result in both a decrease of CPU consumption and end user response times, the perception of DBA activities at the C-level sometimes is more of the kind “why didn't they do that before?”.
This presentation helps you to better understand the C-level perspective and shows you how we managed to improve the image of the DBA team from a reactive team of techies to a proactive team that is directly involved in improving the business results.

In March 2013 the IDUG DB2 11 Editorial Committee was formed, comprised of volunteers from IDUG’s worldwide community of DB2 users and consultants. Working alongside IBM's formal Early Support Program (ESP), the Editorial Committee gained valuable insight into exactly what makes the new release tick. The White Paper, available on the IDUG web site, contains their findings, including practical experiences and independent evaluations of the new features.
DB2 11 contains a large number of enhancements, but some will be of more interest than others depending on your job role and background. The paper has been organized according to the features likely to be most applicable to each of the three major technical roles in a DB2 for z/OS environment: Systems Programmers, Database Administrators and Application Developers.
This presentation from the IDUG EMEA 2013 Technical Conference looks at some of the key findings presented in the paper.
IBM InfoSphere Optim Workload Replay can significantly improve your database testing experience and help you successfully manage change in your database environments, whether you are adopting BLU Acceleration, upgrading DB2, or making the move to DB2. Using InfoSphere Workload Replay, you can build realistic testing environments to help assess a wide range of database changes before production deployment and without extensive script creation or application setup. This makes the change process faster and less risky.
In this session, we will examine the use of InfoSphere Workload Replay to facilitate database testing in efforts to validate version, platform or infrastructure changes. We will discuss how to use the tool to prepare for BLU Acceleration, and review some of the key use cases. Learn the testing methodology and the various features to control capture, replay and generate reports. Using this realistic testing approach you will find key issues sooner in the test cycle, and resolve them before the deployment day.
