A Goal-driven Auto-Configuration Tool for the Distributed Workflow Management System Mentor-lite

s to form so-called "virtual enterprises". A communication manager is responsible for sending and receiving synchronization messages between the engines. In order to guarantee a consistent global state even in the presence of site or network failures, we have built reliable message queues using the CORBA Object Transaction Services. For administration, Mentor-lite provides a Java-based workbench for workflow design, workflow partitioning across multiple workflow servers, and a Java-based runtime monitoring tool. 2 The Auto-Configuration Tool A distributed configuration of Mentor-lite consists of different workflow servers (i.e., instances of the workflow engine), application servers, and one communication server (i.e., ORB). Each server of the first two categories can be dedicated to a specified set of workflow activities and invoked applications, resp., on a per type basis. Each of these dedicated servers and also the communication server can be replicated across mult

A Goal-driven Auto-Configuration Tool for the Distributed Workflow Management System Mentor-lite

The Mentor-lite prototype has been developed within the research project "Architecture, Configuration, and Administration of Large Workflow Management Systems" funded by the German Science Foundation ({DFG}). In this paper, we outline the distributed architecture of Mentor-lite and elaborate on a goal-driven autoconfiguration tool for Mentor-lite and similar workflow management systems ({WFMS}). This tool aims to recommend an appropriate system configuration in terms of replicated workflow, application, and communication servers, so as to meet given goals for performance, availability, and performability at low system costs. The demo will show the monitoring capabilities of Mentor-lite and the various components of the autoconfiguration tool
