Learn how to easily run SQL, PL/SQL, and shell scripts on a large number of databases and hosts.  The open source program Method5 provides agentless remote execution, built entirely inside Oracle.  Remote execution lets us find, fix, and prevent problems that could never be solved one-database-at-a-time.  Querying and controlling all our databases starts with this…

Many DBAs and Architects think they understand Oracle database replication. But it is often only physical replication, as performed by Data Guard, rather than logical replication as done by GoldenGate, Streams and others. There are 3 fundamental principles that govern how these logical replication tools operate, centred on conversion, identification, and conflict handling of the…

Reducing work done by the database is key to improving performance in Oracle-intensive applications. The Server Result Cache allows applications to virtually eliminate work done when processing repeated queries. For applications dealing with growing data sets, this ability can be very beneficial. The presentation will begin by focusing on SQL Query Result Cache and PL/SQL…

What does “autonomous” really mean, and what makes the database autonomous? If you’re looking for an answer to this question, this session is for you. In this session, we’ll cover the many benefits of autonomous capabilities and invite you to take a peek under the hood for a deep dive into the machine learning algorithms…

One of the most critical aspects of building effective systems is the successful management of unstructured/semi-structured information. The database is no longer only a place to store dollars and cents for the purposes of accounting. Efficient manipulation of JSON has become one of the most critical elements of contemporary database infrastructure. Even though you can…

This session will provide a blue print for customers to achieve Maximum Availability using  using Oracle RAC and Data Guard. We will go over the internals of the Architectures involved along with recommendations on each layer so Customers can attain maximum availabiliity.

The Oracle Database Security Assessment tool offers the databsase administrtor the ability to check their database environments to understand the risks that exist to their environment.  Knowning where the environment is not following security best practices, where there are open known security risks is the first step is closing those risks and hardening the environment. …

New DBA's hear stories from their experienced peers about databases being recovered from certain failure and the heroics involved, but what's the reason for those successes? One of the main tools, used by the savior DBA, is the Recovery Manager: RMAN. We're entrusted with our customer's data and the novice DBA has to know how…

Is sometimes difficult to quickly identify the root cause of a performance issue in the database. Automatic workload Repository (AWR) contains most of the information needed to identify these issues, but it could be overwhelming due the amount of data and statistics. Then, there's a need of a method to quickly identify if the database…

A new database architecture called sharding was introduced in Oracle 12cR2 database for linear scalability and complete fault isolation for OLTP workloads. This Oracle sharding architecture partition horizontally partitions data across discrete Oracle Databases (shards). All shards collectively form a single logical database. Come to this session to learn this new architecture and the related…
