Performance Days

The Event to gain maximum Oracle Database knowledge and to meet international specialists from all over the world. 
Oct. 27. & 28. 2020, Zurich, Switzerland


Meet international oracle database performance specialists and improve your skills

Trivadis organized the 9th Performance Days congress with top guest speakers in Zurich. This year’s focus was on Oracle Database performance and query optimization. Since performance is not simply a product one can buy but rather the results of an accurate planning and a correct implementation, the seminars present valuable techniques not only for troubleshooting performance problems, but also to avoid them in first place.

2019 was a blast!

What you learned

Performance Days provided a lot of valuable and practical information to diagnosing, resolving and avoiding performance problems in applications involving Oracle Database.

The speakers covered topics such as:
  • New indexing and partitioning features introduced in Oracle Database 18c and 19c
  • Why it is of paramount importance to keep your SQL statements simple
  • The role of the infrastructure in Oracle Database performance
  • Using resource management to deliver predictable performance
  • In-depth look at how Oracle Database processes joins and star queries
  • Leveraging execution plans for problem solving
  • Using Oracle's kernel debug, diagnostics and tracing infrastructure as well as ASH for troubleshooting
  • Why you probably do not need to read a 10053 trace file
  • How to gather object statistics
  • Tracing parallel executions to better understand how it works
  • What parent and child cursors as well as adaptive cursor sharing and statistics feedback are
Exclusive Speakers

Who were the exclusive speakers on the 9th "Performance Days" Convention?

Christian Antognini

Christian Antognini is a strong believer that at the core it is all about the data, and on how effectively companies process and take advantage of it. For that reason, since 1995 he has focused on the efficient use of database engines. His main interests include logical and physical database design, query optimizers, and basically everything else related to data processing and application performance management. He is currently working as a senior principal consultant and trainer at Trivadis in Zürich, Switzerland.

If Christian is not helping one of his customers get the most out of databases, he is somewhere lecturing on application performance management or database performance features. In addition to classes and seminars organized by Trivadis, since 2001 he has presented at 100+ conferences and user-group meetings in two dozen countries. He is a proud member of the OakTable Network and is an Oracle ACE Director.
