Oracle MAA Building Blocks: RAC und Data Guard
Oracle Maximum Availability Architecture (MAA) offers proven concepts for high availability, reliability, and uninterrupted database services. The two central building blocks are Oracle Real Application Clusters (RAC) and Data Guard. However, between theory that sounds good and stable practice, there are often unclear details, unexpected side effects, and critical design decisions.
In this presentation, the speaker draws on over 20 years of project experience with RAC and Data Guard. Technical fundamentals, typical pitfalls, architectural concepts, performance tuning, storage design with ASM, and organizational and licensing aspects are covered. The focus is on the smooth interaction of these technologies in the spirit of MAA – from load balancing to disaster recovery.
The presentation offers honest recommendations, concrete configuration tips, and empirical values from productive system landscapes. The whole thing is supplemented by historical classifications and anecdotes from the everyday life of a RAC architect – with a focus on what will (still) matter in 2025.

Gateway to Hell – Network Basics for DBAs, DEVs and DevOps
New environments are increasingly based on a software-defined data center, both on-premises and in the cloud. However, more conventional approaches also require database administrators or DevOps teams to understand and handle the network stack. Knowledge of this basic technology is more relevant today than ever before – even if, at its core, it is mostly a creation of the 1980s and 90s.
With a twinkle in our eye, we answer the following questions, among others:
– What’s so great about the Classless Society?
– What does a salami pizza have to do with network technology?
– If Superman likes supernetting, who does subnetting?
– How do nuclear weapons affect network design?
– If my routes come from the GPS, what do I need a router for?
– Who has DNS in their DNA?
We would like to invite all DBAs, developers and DevOperators to rediscover the basics of network technology with us. Everything seen through the practical eyes of experienced, strictly practice-oriented database experts. The lecture is therefore aimed at experienced IT professionals who (only) have little to do with network technology in their day-to-day work and would like to widen their view.
