14:00 - 15:00		 European SQLAdria Seminar – Šibenik 2017 Protecting "The Crown Jewels" – Your Data

This presentation will start by looking at why your application data is under threat and how hackers are no longer ignoring the Mainframe as a source of high value sensitive information. It will then move on to describe the features and functions, such as column level security, column masking, audit policies and trusted contexts, supplied out of the box with DB2 for z/OS to help automatically protect this sensitive and valuable data in your applications.

16:00 - 17:00		 European SQLAdria Seminar – Dubrovnik 2015 Resetting Your Pain Threshold

The internals of DB2 and the way it is used have changed over the years although sometimes the methods and rules of thumb we use to monitor it haven’t kept pace. This session will take a look at some of the metrics we should be monitoring, explain why and, where appropriate, suggest credible thresholds you should be implementing to help you proactively monitor your subsystems and data sharing groups. Helping you catch issues before they turn into real pain.

16:00		 SQLAdria Seminar – Dubrovnik 2011 Back to the Future

With DB2 10 IBM introduced the concept of Temporal Tables, providing the ability to associate data with a period or point in time. The vast majority of business applications rely on some notion of time. This innovation will help to drastically reduce the volume of application logic required to manage different, time constrained, versions of application data. This session will cover the various flavours of Temporal Tables and dig into the mechanics of what happens when the data in these tables is altered.

To firstly look at the real business reasons behind why we tune and why a little knowledge can be a dangerous thing when it comes to SQL. The bulk of the presentation will concentrate on illustrating how SQL can be ‘tweaked’ to produce better performance at a cheaper cost.

Outline:
Why do we tune?
What are the benefits?
Tuning SQL
Tips, techniques and pointers

Full Abstract:
Get more from your SQL, this section will cover how to tune your statements to provide the best return with the least resources. It’s often easy to get SQL to return the data you are looking for...but could you be doing it better?

Outline:
The DB2 Catalog
A brief History
Real Time Statistics
Distribution Statistics
Including Histogram Statistics
Defining, detecting and fixing column correlation
A look at the importance of good filtering

Full Abstract:
We spin a lot of cycles collecting them, how can we get the best out of them? A look back at how the catalog has grown in recent releases and what DB29 brings us in this area. We will also take a look at column correlation, what it is, how to detect it and how to fix it. Real Time Statistics, filtering and the importance of Distribution Statistics are also covered.
