The goal of the paper is that each can find a part of the material that is new and useful - an SAP BASIS administrator with experience on other databases will see some of the DB2 specific tuning tools and techniques, and DB2 DBAs with experience in traditional DB2 environments will see some SAP specific tools and techniques. When doing performance monitoring for SAP on DB2 for OS/390, there are many different layers (SAP BASIS, SAP functional, DB, OS, network) and a variety of tools involved. Some problems can be solved in one layer, but some require monitoring and analysis in several layers. One of the goals of this paper is to show how to follow a problem through the various layers to the source.
