Miscellaneous Shell Scripts1.1 IntroductionThe Unix for Oracle DBAs Pocket Reference is a quick reference describing the Unix commandsmost often used by Oracle database administrators. Its the result of my 20 years of accumulatingUnix tips and techniques. For each of the commands included in this book, Ive provided the basicsyntax and a short, illustrative example. This guide also contains many short Unix scripts that shouldsave you dozens of hours of manual effort.Ive organized the commands and examples in this book into the following major topic areas:Understanding Unix Gives you a little bit of the history of Unix and tells you some things that you need to know regarding case sensitivity, safety, and shells.Building Unix Commands Describes the process of creating complex Unix commands for Oracle.Unix Server Environment Describes the commands that make Unix easier for DBAs.Process Management Describes the basic Unix commands you use to display and manage server processes.Server Values Shows you how to display relevant server values in Unix.Memory and CPU Management Shows the main commands used to display information about memory segments, swap space, and semaphores used by an Oracle database. Also covers commands used to monitor CPU utilization.Semaphore Management Shows you how to monitor semaphore usage by your Oracle server and how to remove semaphore sets for an instance that has crashed.System Log Messages Shows you how to view operating-system log files.Server Monitoring Describes the details of using the server utilities vmstat, sar, and glance.File Management Describes commands that assist in file management tasks.Disk Management Shows you how to get information about the disks on your system. This section includes commands to list physical volumes, logical volumes, and mount points.Miscellaneous Shell Scripts Presents a number of shell scripts that Ive found to be useful over the years, but that dont fit into any of the other sections.Writing this pocket reference was especially challenging because of the dialect differences betweenthe major implementations of Unix. For example, commands in HP-UX are often different fromthose in Sun Solaris. Ive emphasized commands that are common to all Unix dialects. Wheredifferences occur, Ive attempted to cover the following platforms: HP-UX, IBM AIX, and SunSolaris. Youll also find some specific dialect commands for IRIX and DEC Unix.In addition to experimenting with the commands shown in this book, I encourage you to read moreabout them in books such as Unix in a Nutshell by Arnold Robbins (OReilly). Also, remember thatthe online Unix manpages are a great source of information about Unix commands. For example, tolearn about the cat command, enter man cat at the command prompt.1.1.1 AcknowledgmentsThis type of book requires the dedicated efforts of many people, and I have worked closely as a teamwith many others who have supported this effort. Foremost, I need to acknowledge the efforts of mywife, Janet Burleson, whose impatience with Unix syntax led to the development of this book.This book certainly would not have been possible wi ...
