This is an excellent Linux reference for an Oracle DBA.



The chapters are as follows:



Chapter 1 - Getting Started

Chapter 2 - Working in the Shell

Chapter 3 - Managing Processes and Users

Chapter 4 - Creating and Editing Files

Chapter 5 - Managing Files and Directories

Chapter 6 - Archiving and Compressing Files

Chapter 7 - Shell Scripting

Chapter 8 - Analyzing Server Performance

Chapter 9 - Viewing and Configuring System Resources

Chapter 10 - Managing Server Software

Chapter 11 - Automating Jobs

Chapter 12 - Implementing ASM on Linux

Chapter 13 - Implementing RAC on Linux

Chapter 14 - Working Securely Across a Network

Chapter 15 - Managing X Windows

Chapter 16 - Managing Remote Servers with VNC



There are also two Appendixes:



A - RAID Concepts

B - Server Log Files



My favorite parts were Chapter 7 and Chapter 11. For DBA's, it is very powerfull to understand how to write shell scripts and automate them. Also, Chapters 12 and 13 are great references for a DBA who has to implement ASM and RAC on Linux.



My Linux admin has also used these chapters to look at some OS configuration issues with RAC and ASM as well as querying disks with oracleasm (for ASMLIB).



Definitely a great resource that has clear and concise steps to follow to get things up and running. No fluff here.
