Oracle Database 11g: Managing Oracle on Linux for DBAs

This course is designed to give the Database Administrator a firm understanding of the components required to successfully deploy an Oracle 11g database on Oracle Enterprise Linux. Students will learn how to configure and verify the Linux operating system for optimal performance with an Oracle database. Students will also learn how to tune the database to take advantage of the Linux operating system and the Enterprise level features of the OS.

The course covers administrative tasks related to the database like file system choices, kernel and memory model selection, automated startup and shutdown scripts, and customizing the database for Linux. Lectures are reinforced with hands-on practices designed to walk the student through the entire installation, tuning, configuration and troubleshooting process.

This course is based on Oracle Database 11g Release 1.
