Chapter 3. Features of DB2 10 and the<br />
zEnterprise System as applied to<br />
SAP<br />
This chapter describes how SAP products benefit from the recent developments by <strong>IBM</strong> on<br />
the hardware side with the zEnterprise 196 (z196) server and in z/OS and DB2 10 for z/OS.<br />
This chapter examines the following areas:<br />
► The features used implicitly by SAP, including the immediate benefits that result from<br />
improvements in the technology stack without modifications of the SAP product<br />
► The features used explicitly by SAP, including the expected benefits and how to<br />
productively use them<br />
Many features that were in part requested by SAP, require modifications to the SAP<br />
solution or require customer intervention.<br />
► The major investments already made by SAP to optimize the combined solution stack,<br />
using the new hardware and software features<br />
This chapter includes the following sections:<br />
► Features implicitly used by SAP<br />
► Features explicitly used by SAP<br />
► SAP modifications to optimize the solution stack<br />
► New access types<br />
