Trivadis is very pleased to organize the 6th Performance Days congress with top guest speakers in Zurich. This year’s 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 seminars will present valuable techniques not only for troubleshooting performance problems, but also to avoid them in first place.



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 will cover topics such as:

  • New optimizer features in Oracle Database 18c
  • How To Correctly Use AWR Reports
  • Thorough look at how external tables work
  • Most common reasons why the optimizer doesn't select appropriate indexes
  • Problems and workarounds related to object statistics
  • Leveraging Data Guard features beyond data protection
  • In-depth look at the trace files generated by event 10053
  • How Oracle Database really manages space inside tablespaces
  • Identifying performance problems in a Multitenant environment
  • What Oracle's in-memory databases can do
