IntroductionWhat Is This Guidebook About?Release 4.6 of the System Administration Made Easy Guidebook continues in the direction of the4.0 version. The primary focus is the importance of the on-going nature of systemadministration. This book is written for an installed system, where all installation tasks havebeen completed. Installation and related tasks, which are usually performed once, have notbeen included in this guidebook.We have tried to group items and tasks in job role categories, which allows this guidebookto be a better reference book.Real world practical advice from consultants and customers has been integrated into thisbook. Because of this perspective, some of the statements in this book are blunt and direct.Some of the examples we have used may seem improbable, but “facts can be, and are,stranger than fiction.”Because system administration is such a large area, it is difficult to reduce the volume towhat can be called “Made Easy.” Although material in this book has been carefully chosen, itis by no means comprehensive. Certain chapters can be expanded into several books [twoexamples are the chapters on disaster recovery (chapter 2) and security (chapter 11)].Although there are chapters on problem solving and basic performance tuning, thesechapters are only introductions to the subjects. This guidebook is not meant to be a troubleshooting or performance tuning manual. Installation tasks are not presented. We assumethat your SAP consultant has completed these tasks.The target audience for this guidebook is: The customer person or team where: The R/3 administrator is from a small to mid-size company with a small (one tothree people) technical team. Each team member in the team has multiple job responsibilities. The system administrator has a basic knowledge of the operating system anddatabase. The junior consultantxxii xxiiRelease 4.6 A/B
