Performance Modeling of the PeopleSoft Multi- Tier Remote Computing Architecture

Center for Information Technology Integration University of Michigan 519 West William Street Ann Arbor, MI 48103-4943 CITI Technical Report 97–5 Performance Modeling of the PeopleSoft MultiTier Remote Computing Architecture Yi-Chun Chu [email protected] Charles J. Antonelli [email protected] Toby J. Teorey [email protected] Complex client-server configurations being designed today require a new and closely coordinated approach to analytic modeling and measurement. A closed queuing network model for a two-tiered PeopleSoft 6 client-server system with an Oracle database server is demonstrated using a new performance modeling tool that applies mean value analysis. The focus of this work is on the measurement and modeling of the PeopleSoft architecture to provide useful capacity planning insights for an actual large-scale universitywide deployment. A testbed and database exerciser are then developed to measure model parameters and perform the initial validation tests. The testbed also provides preliminary test data on a proposed three-tiered deployment architecture that includes the Citrix WinFrame environment as an intermediate level between the client and the Oracle server.
