Tailored to the needs of people who know Oracle, SAP R/3, or a little of both, Oracle SAP Administration explains the conventions and utilities that integrate these software tools before getting into optimization techniques and strategies for achieving increased data safety. Appropriately, author Donald Burleson emphasizes optimization of disk-access operations. He relates two methods for identifying I/O hotspots–specifically, he shows how to examine the Oracle file statistics and how to use Unix’s iostat utility to get a picture of what’s going on. He then describes strategies for restructuring tablespaces to minimize holdups. He also discusses RAID implementations, their performance penalties, and the increased level of reliability they provide.

Beyond file system considerations, Oracle SAP Administration describes how to reorganize tables, tablespaces, and indexes to achieve top performance. You’ll find explicit listings of SQL statements and Korn shell scripts that restructure databases, plus a wealth of diagrams that illustrate how inefficient databases differ from optimized ones (a concept that’s not always easy to communicate in text). The author tackles Oracle’s parallel-processing solutions and explains how they (particularly the ones that came before Oracle8) interact with SAP. A quick discussion of how very large Oracle/SAP databases behave rounds out this coverage of a robust enterprise duo. –David Wall

Topics covered: Naming conventions, SAPDBA, SAPGUI, optimizing file access, reorganizing Oracle objects for better performance, administration tasks and utilities, and Oracle Parallel Server (OPS) as it applies to SAP. Burleson uses SAP R/3 and Oracle versions 7 and 8 in his documentation.

Product Description
While thousands of organizations use both the SAP business system and the Oracle database management system in combination, until now there has been no book that described the intersection between the two systems. This concise book is aimed at experienced Oracle database administrators, system administrators, and developers who are using either Oracle8 or Oracle7. It emphasizes the differences between traditional Oracle administration and Oracle/SAP administration, and it supplements the Oracle and SAP documentation. The book covers the most useful administration tools, SAPDBA and SAPGUI. It provides recommendations for the most efficient placement of data files; monitoring databases; reorganizing tables, tablespaces, and indexes; backing up and recoving databases; and tuning Oracle/SAP databases for best performance. There are chapters on special issues for parallel processing and for very large SAP databases, and a summary of additional resources for the Oracle/SAP administrator. The tried-and-true tips and techniques in this book should save you hundreds of hours of aggravation while you adapt to using Oracle and SAP in combination.
