European SQLAdria Seminar – Dubrovnik 2015 Practical exploitation of DB2 LUW auditing
Often, there is a need to track the activity of an application or the actions of a user on a DB2 database. Whenever you need to profile a new application, to troubleshoot a weird behaving program, or to simply keep track of what changes administrators are doing, the DB2 audit facility can be of help.
“What is this user doing?” - “What are the most executed SQL statements?” - “Who is connecting to this DB2, and from where?” - “How many rows were modified?” - “How many rows were returned?”… You will find that the DB2 audit facility can answer these questions and many more. Easy to implement and quite powerful, the DB2 auditing facility deserves to be kept at hand. So the purpose of this session is to provide you with a quick introduction to its practical use.

European SQLAdria Seminar – Dubrovnik 2015 The one man dba team: how automation can save the day
Often, the number of databases, subsystems, applications, and tasks are in disproportion to the number of database administrators. Often, a small number of DB2 professionals have to manage a vast number of processes and operations. Automation can help to leverage the power and efficiency of well designed and repeatable processes. Automation can help to alleviate the database administrator workload making his/her life easier.
This session discusses common industry examples of practical application of ready available automation tools to administer DB2 for LUW environments.

European SQLAdria Seminar – Dubrovnik 2014 What’s new for SQL optimization in DB2 for z/OS
DB2 for z/OS is a solid, a mature, and a state of the art database management system.
But despite more than 30 years of development, DB2 continues to add SQL Optimization features that help to get the most of DB2 for applications with every release. These are great news, but you have to make sure that you can get the best advantage of this for your environment.
This session describes changes in the DB2 Optimizer that provide new query access path and query optimization enhancements with query rewrite and predicate evaluation.
We will see how recent changes can help to reduce CPU and Elapsed time of complex queries in a dramatic way. We will review how the DB2 Optimizer interfaces with a DB2 Analytics Accelerator and the controls that you can use at your advantage.
We will discuss about the improved zIIP query offload and how it can help to reduce total cost of ownership and, in some cases, to improve performance.       
 
This session is an update on what is new, what is great, and what is not so great in DB2 10 and DB2 11 in DB2 for z/OS SQL Optimization. We will discuss things that you have to know, and we will demystify the DB2 Optimizer to help you to get the most of DB2.
