What you will learn
This Oracle Linux Advanced Administration training is ideal for experienced administrators who need to learn more about advanced features of Oracle Linux. You'll learn to configure network and authentication services, implement virtualization technologies to more effectively manage system resources, and deploy new types of file systems to improve performance and increase data integrity, while developing troubleshooting and advanced storage administration skills.

Learn To:
- Automate installation using Kickstart.
- Recover from boot errors.
- Address today's large storage requirements.
- Manage resources to deliver consistent response times and performance.
- Allocate system resources to specific Linux processes.
- Use DTrace to identify performance bottlenecks.
- Configure the Oracle Cluster File System.
- Use new technologies, including Linux Containers.

Benefits To You
After taking this course, you will be equipped to use the advanced features of Oracle Linux to get the most out of your systems and applications. Discover how to take advantage of XFS, which improves file system performance, and Btrfs, with its data integrity, copy-on-write, and snapshotting functionality. You'll also learn how to use Control Groups and Linux Containers to increase your resource utilization by creating secure, isolated environments on a single host.

Gain Hands-On Experience
Extensive hands-on practices will guide you through each concept. You will install different types of file systems, including OCFS2, XFS, and Btrfs. You will also experience how to share storage devices across multiple systems, allocate system resources such as CPU, memory, network and I/O bandwidth to critical processes.
