Get the most out of Oracle Data Guard
If you use Oracle Data Guard feature just for data protection, you are using less than half of its potential. You already pay for it, so why not getting the most out of it? In this session I will show how you can use Oracle Data Guard capabilities for common tasks such as database cloning, database migration and reporting, with the help of other features included in Oracle Database Enterprise Edition.

Maria Colgan and Gerald Venzl

An Insiders Guide to Database In-Memory
For more the past 40 years, Oracle has extended the database with industry-leading innovations, never breaking its pledge to bring your existing applications and DBAs along with us. That trend continues, with the introduction of Oracle Database In-Memory, an In-Memory column store. But how does it work and what steps do you need to take to successfully implement In-Memory in your environment? This session explains in detail how Database In-Memory works and will discuss how it integrates with Oracle’s existing performance features, including the Optimizer, indexes, materialized views, and the Exadata platform.
What’s new in Oracle 18c
Oracle Database recently switched to a new annual release model, and Oracle Database 18c will be the first release in this new model. This session is a unique opportunity to get ahead of the curve and learn what’s new in Oracle Database 18c directly from the Oracle Database development team.
IT Wars – DBA Versus Developer
For decades developers and DBAs have battled over who controls the world. With each new development paradigm the battle flares again as developers push DBAs to adopt and support new data structures (JSON), new APIs (REST services), new technologies (In-Memory) and new platforms (Cloud). In this session, Gerald takes on the role of lead developer on a project to deploy a RESTful web-based application, while Maria takes on the role of the DBA. Through the use of live demos, they learn to work together to find a solution that will allow them to embrace a more agile development approach, as well as the latest technology trend without exposing the business to painful availability or security vulnerabilities.

Python for Oracle Professionals
Why should you learn about Python? It's language of data science. It’s beneficial for career
enhancement or even understanding many python apps and system management tools. In this session
learn to start using python from the context of the SQL and PL/SQL language to jumpstart the process
and make easier. Learn the basics and intermediate python, draw charts and oconnect to Oracle
database using CX_Oracle. All will be explained with live examples and the code samples will be
available for download.
1. Learn basics and intermediate topics in python quickly
2. Learn how to pull data from and put data into an Oracle database using python
3. Learn how python can be used in many situations including Oracle DB management

Real World DBA Best Practices in the Cloud
Learn some of the tips and techniques of successfully managing a database infrastructure in the real
world from someone who has been a DBA for 22 years and counting. Each recommendation is explained
with justification and how it works. Some examples – install patches in a different Oracle Home, enable
simple auditing, RMAN validate and restore preview, prefer pfile over spfile and many others. This
presentation was delivered at Collaborate conference earlier to a packed room. This session have been updated since
1. Develop an arsenal of tools for use in any database infrastructure
2. Debunk some of the widely accepted theories on best practices
3. Learn the tips and techniques for managing the database from a practical context
Diagnosing Latch Contentions in Oracle Cloud Databases
Often contentions for latches cripple systems to a halt, even to the point a DBA can’t even login to check
the source of the issue and take corrective action. In those cases you may have no choice but to recycle
the database, only to see the recurrence of that same issue, and a lot of upset customers who lost their
data. In this session you will see how to troubleshoot latch contention issues with proper tools, even
when the database is not accessible to SQL, using oradebug, prelim option and using hang analyzer trace
files. You will learn a specific set of steps to follow to identify the root of the issue and resolve it instead
of recycling the database. All will be explained with live demos.
1. Learn why latch contentions occur
2. Learn how to use oradebug and hang analyzer
3. Learn how to identify cache buffer chain latches

Enabling Self-Service Analytics With Analytic Views & Data Visualization From Cloud to Desktop
Self-Service Analytics is replacing the traditional IT-driven by enabling end users to design their own reports with minimal assistance. Oracle tools like Data Visualisation Cloud and Desktop, or the Analytics Cloud Suite are perfect for this purpose.

The dark side of Self-Service Analytic is that it requires additional knowledge: datasources, relations between items and aggregation methods are only few of the concepts which end users need to assimilate before producing results. Self-Service Analytic tools providing only some support in this area based on column names, types or values.

What if dimensions, hierarchies and aggregation methods could be retrieved directly in the source system? Analytic Views provide exactly that: a new way of modelling metadata directly in the database.

In this presentation we’ll see how to define attributes, hierarchies and metrics in the Analytic Views on top of existing data structures and how end users can benefit when using self-service tools
