Abstract: Bank posting and balancing operations (discussed in more detail in the paper) are often called core banking. These processes are crucial to all commercial banks. Historically, core banking was one of the first parts of a banking operation automated with computers. Not only is it crucial to the bank’s business, but it generally has the highest processing volumes and resource requirements and has extremely high availability requirements. According to some sources, core banking was done mainly on mainframes – mostly as custom developed CICS or IMS applications. However, changes in the competitive market place as well as legal and regulatory requirements have caused many banks to consider application packages from vendors such as SAP AG. These packages can provide quick to implement and less expensive applications that support new competitive environments as well as assured compliance with new regulations and can provide more integration with other business processes.

However, banks want to have the confidence that the application, and the platforms it runs on, can support their business volumes. This is especially true for large banks. The purpose of the measurements shown and discussed in this report is to help demonstrate large core banking business volumes. In particular, we concentrated on the Database Server (DB Server) and DB2 10 for z/OS, as they are key to an SAP solution-based system’s scalability and availability.

SAP’s Banking Services (SBS), and its core banking component, are part of the SAP for Banking portfolio. For many large banking customers, core banking is the most resource intensive part of the solution. This is because it often has critical windows within which all the processing must be completed. For example, some customers want to complete all the account balancing activity at month end in one night. Often banks also have near continuous availability and high security requirements. To discuss and help satisfy these and other banking needs, SAP has co-authored a paper with IBM, “SAP for Banking on System z Reference Architecture”.

We have a long history of working with SAP on core banking. For example, there were a set of core banking measurements done in 2002 with DB2 V6 for z/OS and a 75,000-account database. Since then we have tested newer versions of the application with newer versions of DB2, and expanded the number of loaded accounts to 5 million and later 40 million. We have over the years published on the web technical papers discussing some of these as well as other experiences with this workload. For example, there are currently four technical papers available on the World-Wide Web.

This paper describes a set of measurements we did with 150 million loaded accounts, SAP AG’s most recent SBS 7.0, our most recent DB2 10 for z/OS, our largest current zEnterprise system, and our System Storage DS8800, the most advanced model in our high-end disk portfolio. Our goal was, within schedule and other resource limits, to reach significantly higher business transaction processing rates in the more stressful 150 million-account environment using SAP’s latest Banking release.
