Track 2 The database platform – the end of progress? expand description

Not any new processors? Not any new disk arrays? The same SAN till the end of the time? Moor’s low not working anymore? Marketing instead of technology?

Over the last decades the enterprise class systems, and database systems as a part of it, was perceived as IT market locomotive.

It was reflected by technology trends, strong attention of most important vendors and – as a result - wide offer of new announced, truly innovative products.

The IT market is still growing dynamically and cover wider area of technology and users activities. The grow caused as an effect deep structural market rebuilding, which has close the market of enterprise solutions as narrow and shrinking niche. The consequences of it make important changes to Enterprise Solutions Market, IT environments and actual availability of new technologies. I have tried to summarize the prominent (and natural) trends from wilder perspective because we, professionals caring about business critical solutions deeply depends of them.

Track 3 Accelerate Development with automation expand description

In this presentation Ron will discuss DevOps and the explore why automation is key to developer agility. Ron will demonstrate how automation can accelerate development and improve quality by ensuring consistent platform configurations and by delivering the right data to the right people, fast!

Lecturer

Ron Ekins

11:00-11:45

Track 1 Deep Dive into the Implementation of Oracle's Join Methods: Past, Present and Future expand description

Join processing in relational databases involves combining the output of two row sources (e.g. tables) into one result row source. Most SQL analytic workloads are dominated by time spent in join processing because of the nature of the operation being heavily compute and bandwidth intensive. Oracle has developed numerous traditional join methods over the years (e.g. nested loop, sort merge, hash joins, etc.). Some of these methods have fallen out of favor over time by the optimizer (i.e. past), others are time-tested and commonly selected by the optimizer to this day (present), and then there's a new class of join algorithms which leverage the latest In-Memory Columnar data formats to deliver the fastest join evaluation known in industry (future). This talk will dive into the technical implementation details of Oracle's plurality of join methods (including specialized ones such as vector transformation which optimizes aggregations over joins), give insight into why the optimizer may choose one method over the other, and what the SQL and storage engines are actually doing under the hood to implement the join.

Lecturer

Shasank Chavan

Track 2 We are Serverless - It still Works. And this (what we think) has happened. expand description

Going Serverless to a cloud-provider gave use some interesting experiences. The result was Positive, but with interesting lessons about the tools (java, pl/sql, python, docker and lambdas), the data, the (oracle-)database, and the people and processes needed to control the new situation.

Lecturer

Piet de Visser

Track 3 Beer Pong: SQL vs PGQL expand description

Track 1 Lunch

14:00-14:45

Track 1 A deep dive into Oracle parsing expand description

As a spoiler/teaser: the documentation is mostly wrong about it, and certain critical parts of parsing can be moved to execution time. Because what is happening is generally considered to be taking place at parsing time, that time is now spend in in sql execution in the statistics, however since it’s considered parsing, that time is added to parsing time too, making it hard if not impossible to understand the statistics if there are actual parsing problems.

Lecturer

Frits Hoogland

Track 2 Long live to CMAN! Or why Oracle still cares about CMAN and why you should do it too expand description

Oracle Connection Manager (CMAN) is the Swiss-army knife for database connections. Starting with Oracle 18c, it has been extended with the new Traffic Director Mode (CMAN TDM), that allows transparent failover for applications that do not implement it natively. Come to this session to know more!
