This paper describes several tests we performed with IBM System z, DB2 for z/OS and SAP’s Bank Analyzer (BA). BA is an integrated family of financial sub-products intended to provide bank management a consistent and prompt view of the institution’s risk and return. It uses data from the institution’s operations. BA supports several industry standards such as Integrated Finance and Risk Architecture (IFRA), International Accounting Standards (IAS), Basel II, Risk Adjusted Performance Measurement, and Sarbanes-Oxley. In particular, we ran SAP’s new Bank Analyzer 7.0 (BA7). We chose this combination because of previous, and continuing, experience with SAP’s core banking applications as well as non-SAP banking and financial services experiences with customers.The focus of our efforts and this paper were on the interactions of the application with the IBM supplied infrastructure. Infrastructure examples are servers, storage subsystem, operating systems, relational database and associated items. We did not focus on BA7 from a functional level. These tests were not performance tests or formal benchmarks. While we did report several performance related metrics, these tests were more in the nature of function tests. There was very limited exposure of the application to the test environment. Sometimes there was just a single run. In addition, there were relatively low business volumes attempted. As a result, there was very limited tuning, investigation of bottlenecks, and investigation of how to scale up the volumes. Further, we ran on relatively old systems with old features and functions. For example, the DB Server’s System z9 was two generations down level from today’s zEnterprise System. This resulted in relatively slow adapters for networks and disks and no capability to use features like zHPF. We did run relatively recent versions of z/OS, DB2 for z/OS. BA7 was new with several functions, features, and extensions added as the tests progressed. The project enabled SAP to enhance this application to run more efficiently with DB2 for z/OS.
