Track 1 OpenTelemetry and Databases: The New Era of Monitoring rozwiń opis
Modern database monitoring is undergoing a paradigm shift with OpenTelemetry (OTel), which provides vendor-neutral, standardized telemetry for both Oracle and PostgreSQL. Unlike traditional siloed tools, OpenTelemetry unifies metrics, traces, and logs into a single observability pipeline, enabling more profound insights into performance bottlenecks, query latency, and resource contention.
Opentelemetries Database Receivers gain from:
Distributed tracing to correlate slow queries with application code
Custom dashboards for real-time visibility into connection pools, cache efficiency, and lock contention
Chaos-ready monitoring by combining OpenTelemetry’s metrics with failure injection testing
The fusion of OpenTelemetry Collectors (receivers/processors/exporters) with databases eliminates proprietary agents, offering scalable, cloud-native observability.
This talk dives into how the OpenTelemetry Receiver works and collects data and current problems. It also explains why your existing monitoring is considered legacy.
We will see why the future lies in declarative database observability—where OpenTelemetry’s extensible schema and open standards replace fragmented monitoring stacks, making Oracle and PostgreSQL as observable as stateless microservices.

Track 3 The Love and No Love with Oracle Performance Tools rozwiń opis
Oracle Database provides a solid set of performance tools that are essential for troubleshooting and optimization. While they are powerful and useful, some aspects are less than ideal. In this talk, I’ll go over the features that work well for me, the ones that don’t, and the changes that, in my view, would make these tools significantly better.

Track 1 How to completely botch your Database Migrations to OCI (and maybe how to avoid it) rozwiń opis
Are you ready to mess up your database migration to OCI, big time? Then this session is for you! I’ll walk you through some of the best ways to ensure delays, confusion, and frustration at every step of your project. From misguided technical decisions to expert-level miscommunication, learn how to make your migration as painful as possible.

Track 3 Online Schema Changes: Real-world Experience with Edition-Based Redefinition rozwiń opis
Rolling deployments have become standard for application updates, but database schema changes remain a major challenge. Developers often resort to workarounds that compromise data quality or require intricate coding solutions.

What if there was a better way? Oracle Edition-Based Redefinition (EBR)—combined with Online Table Reorganization—can seamlessly evolve database schemas without downtime.

In this session, we'll start with the fundamentals of EBR before diving into a real-world case study with ČSOB, a major financial institution from the Czech Republic. You'll hear firsthand how they leveraged EBR to implement zero-downtime schema changes, ensuring business continuity while lowering deployment risks. We'll also demonstrate a live deployment to showcase EBR in action.

Track 1 Path of suffering and hit pattern - CIS Benchmark and hardening for beginners rozwiń opis
This is our project report on the subject of hardening project systems on a Linux basis and with the Oracle database on top. Since it has come to us completely out of the blue, even as "Oracle users" and "Linux users" with many years of experience, we first looked around and wondered what is to be learned in the security environment! It is the story of criminal energies, self-restrictions, risks to be taken, unknown threats, dear habits, external determination, reality, practice, performance, overhead, overview, tools and the question of who is supposed to maintain all this?

Join us on the road which should lead to greater security - but at what cost?

Track 2 Performance Optimization: How do start rozwiń opis
I face this situation again and again in practice. The beginning is always a hurdle. For me, the point at which I can relax is only reached when I have runtime statistics available for execution plans. Until then, however, it is a journey with several alternative paths.
After 30 years of performance analysis, I do indeed have something of a script in my head that I follow. I would like to show you my first steps and the decision points at which you need to question your approach. Among other things, the following questions will be answered: What tools do I have, what do I use when and where are the pitfalls?

Track 3 A Brewery Use Case for Data Use Case Domains in Oracle 23ai rozwiń opis
Finally, Domains are available in Oracle! – "Data Use Case Domains” are one of the major SQL enhancements in Oracle 23ai. But what are typical use cases for this new feature? In an extensive live demo, the speaker (and hobby brewer) will show how we can create a data model for a craft beer brewery with different types of domains.

Track 1 Upgrade Internals rozwiń opis
Oracle AutoUpgrade has made upgrades so easy that there really is no need to know the inner workings of an Oracle Database upgrade. But we’re techies – and techies are curious and want to tear that black box apart and know about bits and pieces inside.

This session covers how an Oracle Database upgrade works and how the upgrade engine changes the data dictionary. It also explains the newer method called Replay Upgrade (which you might be using already without knowing). Further, the session describes the “lightweight” AWR that is active during an upgrade, where the normal AWR is inactive. This will help us shed some more light on what happens during an upgrade. Finally, the session shows you some advanced features in AutoUpgrade and how you can use them to tweak an upgrade.

If you’ve never upgraded an Oracle Database before you can gain valuable insights from this session. Plus, experienced “upgraders” can learn a few more tricks to put in their toolbox for the next upgrade.

Track 2 Fighting Bad PL/SQL & SQL with VS Code rozwiń opis
Improving code is like losing weight. First, you need to know what is good and what is bad. You need metrics and appropriate measurement tools to express your goals and achievements. Then you get results as a series of small steps in the right direction.

In PL/SQL and SQL, code complexity can be expressed in lines of code, number of statements, as McCabe's cyclomatic complexity, Halstead's volume, or the maintainability index. Reducing complexity is one way of improving code quality.

However, in this talk I will focus on coding guidelines for PL/SQL and SQL and discuss my favourite guidelines. These guidelines are actually rules and must be followed. Therefore, there is (almost) no room for different interpretations. So, if we violate any of these rules, it means our code is broken. I will show you how you can use the dbLinter extension for Visual Studio Code to find these bugs in your code and fix them manually or even automatically.

By the end of this session, you'll know how to check your code in Visual Studio Code and efficiently eliminate bad code.

Track 3 Agentic Systems: empowering AI to achieve goals rozwiń opis
Everybody already played with an LLM, asking the most random questions and seeing what kind of answer they got. That is precisely what ChatGPT was like at first: an LLM receiving an input and generating an output. All other AI services started like this, just a different LLM model behind the screen.
But, if you look at ChatGPT today, you already see how much it did evolve. You ask a question, and instead of having a generated answer right away, there are extra steps to find the best answer first. For example, it will search online for content to help produce a better answer. That is an example of agentic behavior.

An agentic system is the next big step in AI-powered automation. It combines the reasoning power of LLMs with the ability to take action with several tools. The more tools you provide an agentic system, the more actions it can handle autonomously, without the need for constant human guidance.

You could believe it's incredibly complex to develop an agentic system. Wrong, it's surprisingly simple!
Join me in this session to show you how simple it is to create an agentic system. We start by looking at some examples, then developing one "live" in 45 minutes using Python and an LLM (or a few).

Track 2 TTT - Total Tuning Theory rozwiń opis
45-minute presentation on the history and practice of Oracle DB tuning – from Oracle parameters and metrics, through AWR, ASH, waits, session analysis, and the full history of SQL queries.
FlameGraph will be presented as an optional visualization tool that helps to more quickly understand complex execution plans.
The goal of the presentation is also to spark a discussion on how to present data in a way that becomes a fishing rod for developers and product definition managers – not just a fish caught in murky waters.
The session will showcase what’s happening inside the database and how it impacts the client’s business.

Track 3 SQL*Net Encryption & Authentication rozwiń opis
We’ll explore Oracle Native Network Encryption and Transport Layer Security (TLS) settings in Oracle Database, starting with encryption basics and configuration examples for both servers and clients.

Next, we’ll dive into TLS setup, discussing client and server authentication using certificates. We’ll also cover the setup and management of Oracle Wallets required for secure communication.

At this point we’ll already know how to authenticate database clients with certificates, so now we’ll also provide a brief example on how we can authenticate them with Kerberos.

Finally, I’ll present best practices on when and how to use such configurations and what other Oracle Database features, such as proxy users, can be used in conjunction with everything described so far.

This session is relevant for any edition of Oracle Database, including Standard Edition.

Track 1 Search and you shall find. A walk through the Oracle 23ai search landscape rozwiń opis
This presentation will discuss AI Vector Search and the new AI Vector Hybrid Search, along with a few other more classic search techniques.

With recent 23ai additions — AI Vector Search, Hybrid Vector/Text Search and Ubiquitous Search — alongside the classic Text Search and Simple Search, understanding these search options is essential for choosing the right approach when building PL/SQL, APEX, and other Oracle applications.

This session explores the characteristics of each search technique, highlighting their advantages and disadvantages through real-world examples, live demonstrations, and discussions. Attendees will gain insights into the factors to consider when selecting and implementing the search approach that best meets their needs.

Track 3 Predictions, Plans and Problems rozwiń opis
Interpreting a query block, the basic unit of an execution plan, is simple (for a serial plan, parallel can be a little harder).

Deciding why each query block exists and how Oracle will connect them when a plan has multiple query blocks is harder, but it's a task that becomes much easier if you can predict all (or most) of the ways that the optimizer might choose to transform your query.

Even if you can "join the dots" correctly, though, you may still find that the work done at various points through the plan exceeds your expectation, so you need to be aware of odd edge effects of the optimizer and the fundamental infrastructure of Oracle and know how to diagnose any anomalies.

This presentation will be a traditional "show and tell" (slides and talk) that starts with a fairly short query and pushes the optimizer (and the audience) to the limits of the possible.

Track 1 Around the World in 80 Dogs: A Rough Guide to the Database Character Set rozwiń opis
Yes, nowadays you can get by just sticking with the default. But this session is for those who want to know a little more.

The default, AL32UTF8—what exactly is it, and why should we use it? Did you know it’s self-synchronizing? Find out what that means and why it’s important. And what about that other character set called UTF8—what’s that, and why shouldn’t we use it? And what’s the deal with the National Character Set?

With the help of furry friends from all over the world—including “dog,” “pies,” “cão,” 狗, “köpek,” “كلب,” 🐶, and 𓃡—we’ll contrast various character sets to compare coverage and efficiency

Track 2 Assertions Creed rozwiń opis
We all use constraints to secure our data integrity, right? Right?
Primary and unique keys to make sure a row is unique in a table. Foreign keys to make sure a row has a matching parent row. Check constraints to make sure data within a row meets certain standards.

The common denominator here is "a row". What about a constraint that extends beyond the borders of a row, to other rows in the table or even in another table or multiple tables?
For example a constraint that will enforce "if a car is leased for an employee (cars table) no options (lease_options table) are allowed that cost more than 5% of the value of the car"

For things like that that you'd have to resort to triggers. And please don't be offended, but there's a high probability you would do it wrong because most people do.

Fear no more. Oracle is the first database vendor who succeeded in implementing a feature from the ANSI standard called Assertions.
Which allows you to enforce such business rules declaratively, like other constraints, and let the database worry about how and when to check it.

This talk will introduce Assertions to you and discuss its benefits and its limitations, some of which are planned to be temporarily.
