Preface<br />
This <strong>IBM</strong>® <strong>Redbooks</strong>® publication describes the benefits of <strong>DB2</strong>® 9 <strong>for</strong> z/<strong>OS</strong>®<br />
and <strong>SAP</strong>® Business Intelligence. It lists best practices and provides per<strong>for</strong>mance<br />
and tuning recommendations <strong>for</strong> <strong>SAP</strong> Business Intelligence.<br />
In today’s fast-moving business environment, there is a need <strong>for</strong> more and better<br />
business in<strong>for</strong>mation. Data wareho<strong>using</strong> and business intelligence (<strong>BI</strong>) systems<br />
deliver that in<strong>for</strong>mation. This imposes new requirements to manage, control, and<br />
use this data <strong>for</strong> business purposes.<br />
<strong>SAP</strong> Business Intelligence is the central reporting tool <strong>for</strong> almost all <strong>SAP</strong><br />
business solutions. It is based on building blocks called InfoObjects that contain<br />
data about customers, sales, and business in<strong>for</strong>mation. InfoObjects include<br />
InfoSources, DataStore objects, and InfoCubes. The business intelligence<br />
solution from <strong>IBM</strong> and <strong>SAP</strong> can help you aggregate and leverage this<br />
in<strong>for</strong>mation, giving you a system-wide view of your business data and delivering<br />
it across your enterprise to support sound business decisions.<br />
However, this structure can lead to slow per<strong>for</strong>mance if the system is not set up<br />
and managed according to good database principles. This book describes best<br />
practices <strong>for</strong> this product on a System z plat<strong>for</strong>m, and provides per<strong>for</strong>mance<br />
and tuning recommendations <strong>for</strong> loading and querying data. It also addresses<br />
general system administration and troubleshooting.<br />
The audience <strong>for</strong> this <strong>IBM</strong> <strong>Redbooks</strong> publication includes <strong>SAP</strong> and <strong>DB2</strong><br />
administrators. Knowledge of these products and of the z/<strong>OS</strong> environment is<br />
assumed.<br />
This <strong>Redbooks</strong> publication is designed to aid the reader based on specific needs.<br />
After describing the product and summarizing its advantages on the zSeries®<br />
plat<strong>for</strong>m, we list best practices <strong>for</strong> the PSA, InfoCube, DSO, and <strong>DB2</strong><br />
components. We give tips on how to gain efficiency by <strong>using</strong> compression and<br />
indexing. We also include a troubleshooting chapter that describes what to do<br />
when best practices do not address a problem.<br />
This edition of the book includes a new chapter (Chapter 11, “Project Jupiter:<br />
large <strong>BI</strong> Accelerator scalability evaluation” on page 227) and an appendix<br />
(Appendix D, “Project Jupiter: evaluation details” on page 325) that describes<br />
Project Jupiter, a joint venture between <strong>IBM</strong> and <strong>SAP</strong> to test the scalability and<br />
per<strong>for</strong>mance of a very large (25 terabyte) database.<br />
