This course prepares a Linux system administrator for managing a system on which Oracle Database has been installed. Elements of how Oracle works on Enterprise Linux and specific steps for preparing Linux for a database installation are covered. This course provides the system administrator, who already has some Linux experience, with the skills needed to diagnose an Oracle Database using system administration tools. The Oracle Database architecture is covered, which will help the system administrator understand what affect database activity and configuration can have on the process list, disk space, memory use, and CPU utilization.

The Linux system administrator will also learn how to perform some tasks that are sometimes shared between the system administrator and database administrator.

The course provides information on how the operating system tools and techniques affect the tasks and settings that are often the DBA’s responsibility. File systems, including OCFS2, network configuration, memory management, and package management using the Unbreakable Linux Network are discussed. Demos and practices reinforce the concepts presented, including the installation and use of several tools that help in gathering diagnostic information that can be provided to Oracle Support Services.
