This paper outlines the results that were collected from the implementation of the COPAR Service  in an Opnet Modeler simulation environment. The system carries out two (2) types of transaction processing techniques; Optimistic (Temporary) and Pessimistic (Permanent) Processing. The Opnet simulation environment was used to expand the projects capacity by increasing the number of servers and transactions that could be processed by the system. Results show the processing times for simulations that ran with nodes ranging from 20 to 100 nodes and transactions ranging from 200 to 1000.
Results also showed statistics for the distribution of transactions amongst servers with different classifications. Classifications of server ranged from 1 to 6, 1 being the lowest and 6 being the highest. The number of transactions used for testing transaction distribution ranged from 1000 up to 4000, with each simulation run using 100 server nodes. These results can act as a guide to help implement systems that can provide optimal processing times in a real world environment.
