Lost in metrics, rescued by pandasrozwiń opis
Database consolidation brings another level to performance analysis. How to measure shared resources utilization, interaction between workloads and consolidation efficiency when running tens of databases on single Exadata or SuperCluster node? To address this challange you should consider tools like Enterprise Manager, BI Publisher or even Python language with Pandas - and I will show you them in practice.

Oracle App Dev tools for Oracle Database, past, present and futurerozwiń opis
You can’t see or modify data within a database without using some tool or driver. My job at Oracle is to provide productivity tools and data access technologies to simplify and improve application development with the Oracle database. This includes Oracle APEX, SQL Developer, JDBC, open source drivers, ORDS, and developer tools for .NET. All are free for use and work with our free Oracle XE database. In this session I will share how challenges are changing and discuss future direction at the intersection of application development and Oracle database.

DBAs versus Autonomous Databasesrozwiń opis
Databases are going to the Cloud. Sooner or later. Most of them perhaps. How does this affect the DBA profession? Accenture conducted a battery of tests looking at Oracle databases in the cloud. Nearly half the world’s data runs on Oracle databases, making them a valuable focal point for such tests.

Where is Waldo? The 0x memory leak edition - Published by Geek Pressrozwiń opis
Everybody knows the children’s book series “Where is Waldo?” and how hard it can be to find this guy in his red-and-white-striped shirt, bobble hat and glasses. The same problem applies to finding memory leaks in Oracle. This will be an interactive talk and with help of the audience I will work out and demonstrate a systematic troubleshooting approach for finding memory leaks in Oracle. Together we will analyze and drill-down a memory leak bug in Oracle’s core/kernel code with help of a very simple and pretty common application case. Be prepared to find Waldo aka. the memory leak!
