Revision with unchanged content. The Performance and Capacity Planning Method for BPEL4WS-based Busi ness Process Automation refers to the ability to predict resource con sump tion of a defined set of business processes automatically executed on an IT ser ver system. A prediction model integrates all factors that influence a re source consumption prediction into a single tool. On the basis of a prediction model an accurate hardware configuration can be proposed which is able to run the defined set of business processes with the required throughput. This book gives a complete overview of how to develop, verify, and apply a performance and capacity planning method for BPEL-based processes in ge neral. In particular, the performance and capacity planning method is established for BPEL-based business processes on IBM WebSphere software. This includes the WebSphere Process Choreographer Version 5.1 workflow engine of the WebSphere Business Integration Server Foundation Version 5.1, WebSphere Application Server Version 5.1, WebSphere MQ Version 5.3 and the DB2 Universal Database Version 8.1.
