Full Abstract:
During this seminar Jan will take you through the important aspects that influence your application performance and high availability. In the last two releases many new features have been added that will have an important impact on the efficiency of your applications. There is a lot of information available in books and articles but this ODS is based on real life cases, many which have been implemented by Jan in customer engagements. All of this with the fundamental principle that we don’t tune and design for the sake of the tuning but to make sure we meet the application objectives.

Full Abstract:
Many DB2 systems are still running as if it where the 90's. There are many reasons for this lack of adaptation but one of the most important ones is lack of time. This means in many cases not lack of time but simply lack of priority. This presentation helps you to look at problem and to build a business case around it. How much will you gain if you make this change. Putting the numbers behind the change will greatly help you with the sell.
