Overview

This Oracle Database 12c: Architecture and Internals training class begins with a discussion of the broad systems infrastructure where one finds Oracle database installations, and we outline how the database fits with other systems in a multi-tiered architecture, including web servers, application servers and engineered systems such as the Oracle Exadata database computing platform. We then explore the intricacies of a single database installation, including memory, process and storage structures. Periodically we delve into the internals of the database, probing into such areas internal locking mechanisms, kernel module calls and database failures.

The target audience is all Oracle professionals: database administrators, application designers and developers, web server administrators, system administrators, implementation specialists, and data center support engineers.

  2. Learn to understand grid computing.
  3. Learn to the background and foreground process architecture.
