IntroductionWho Should Read This Book?Senior consultants, experienced system administrators, and DBAs may find portions of thisguidebook very elementary, but hopefully useful.To help you use this guidebook, and to prevent this guidebook from becoming as thick asan unabridged dictionary, we defined a baseline for user knowledge and systemconfiguration. The two sections below (User and System) define this baseline. Review thesesections to determine how you and your system match. This book is also written withcertain assumptions about your knowledge level and the expectation that particular systemrequirements have been met.We assume that you have a baseline knowledge of R/3, the operating system, and thedatabase. If you lack knowledge in any of the following points, we recommend that youconsult the many books and training classes that specifically address your operating systemand database.You should know how to complete the following tasks at the: R/3 System level: Be able to log on to R/3 Know how to navigate in R/3 using menus and transaction codesThere are screens that do not have menu paths and the only way to access them is byusing the transaction codes. In the “real world,” navigating by transaction codes isfaster and more efficient than menus. Operating system level: Be familiar with the file and directory structure Be able to use the command line to navigate and execute programs Set up a printer Perform a backup using standard operating system tools or third-party tools Perform basic operating system security Copy and move files Properly start and stop the operating system and server Database level Properly start and stop the database Perform a backup of the databaseR/3 runs on more than five different versions of UNIX. In many cases, significantdifferences exist between these versions. These differences contributed to our decision tonot go into detail at the operating system level.System Administration Made Easyxxiiixxiii
