Oracle Database 11g: Implement Streams Release 2

The Oracle Database 11g: Implement Streams course is a hands-on introduction for Streams Administrators, DBAs and others who need to know how to share data and messages between schemas, applications, and Oracle databases which can be continents apart.

This course begins with “Guided Configurations”, both in Oracle Enterprise Manager and via command line (using PL/SQL packages). The second unit addresses “Manual Configurations”, which is followed by “Customizing your Configurations” with transformations and apply handlers.

The unit on “Extending Streams” includes topics such as Configuring Downstream Capture, Synchronous Captures, XStream, and extending the Streams configuration automatically, with a single MAINTAIN procedure or wizard, or by adding components individually in multiple steps.

The last unit on “Managing and Monitoring Streams” includes the split-and-merge functionality, analyzing and avoiding data conflicts, comparing data, best practices and troubleshooting guidelines. The appendices can be used to address additional customer needs, such as Advanced Queueing (AQ).

This course is based on Oracle Database 11g Release 2.
