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.
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.
A well designed application should look beautiful and , maybe more essential, perform outstanding. In this session the focus is on the latter. With APEX it’s just too easy to make a mess of your application. Keep things structured and you’ll be happier.
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.

Increase your programming confidence by using Unit Tests.rozwiń opis
Everybody knows how important testing is, but hardly any developer writes repeatable tests. Sure we create tests to make sure our code works, but this is hardly repeatable. This session will show you how Unit Testing can help your developers getting more productive and confident about their code.
Unplug yourself from APEX’s declarative limits! But APEX declarative functionality is limited, not providing the full capabilities of what is possible with web technologies these days. Fortunately APEX offers a mechanism to expand functionality in a declarative way: Plugins.

It’s possible even without knowing what the environment looks like.
Oracle keep saying default setup of their database works well most of the time. But some of those defaults lead to different issues often enough to question why it is done this way. This talk will be about such defaults.
