Performance Days

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


Meet international Oracle Database performance specialists and improve your skills

Trivadis will host the 11th Performance Days congress with top guest speakers. As in the previous years the focus will be 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 talks will present valuable techniques not only for troubleshooting performance problems, but also to avoid them in first place.

Impressions from last year!

What you will learn

Performance Days will provide 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:
  • How you should be measuring and testing your upgrades and migrations
  • Most common performance problems and how to troubleshoot them
  • In-depth look at how Oracle Database parses SQL statements
  • Problems, workarounds and common practices related to object statistics and indexes
  • Which technologies enhance and in some cases self-tune performance in an ADW environment

  • Leveraging the query rewrite capabilities of materialized views
  • Thorough look at the performance of parallel hash join
  • How to design and build database applications that are easier to monitor, manage, and maintain
  • What are the features that Oracle Database provides to improve the performance of distinct operations?
  • How the logwriter really works
  • New performance-related features in recent Oracle Database versions
Exclusive Speakers

You can look forward to these speakers at the 11th annual Performance Days
