Oracle Database 10g: 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 10g Database on Enterprise Linux. Students will learn how to configure the Linux operating system for optimal performance with an Oracle database. Then they will install and create an Oracle 10g database on Linux. In addition, the 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.

Learn To:

• Optimally configure Linux for an Oracle Database installation
• Customize the database to take advantage of Linux features
• Monitor memory, CPU, and I/O activity and performance
• Identify the different kernels and memory models available for Linux
