Each of the 10,000 users was performing a variety of transactions, some simple and some complex, all typical of real life for the proposed system. There were 30 individual activities in the scenario, designed to provide a simulation of the proposed production work load. All of the activities were performed by each user. This included creating new orders, key look-ups, index look-ups on full and partial values, a multi-screen maintenance procedure, and others. The actual production code was used, including all entry screens, to ensure there would be no concerns about a "mocked-up" simulation. Simulated users were pushed from a p570 running 4 LPARs so the burden of administering the load would not be imposed on the database server. The simulated users appeared to the database server as telnet sessions, again to most closely simulate a real-world scenario. The initial goal was to make sure UniVerse could handle the proposed production load and that a file of greater than a terabyte with over a billion rows would not cause problems. Since we had some spare time at the benchmark center after proving that, we ramped up the users by another 50%, just for fun. ;-) Tim Snyder Consulting I/T Specialist , U2 Professional Services North American Lab Services DB2 Information Management, IBM Software Group 717-545-6403 [EMAIL PROTECTED] ------- u2-users mailing list [email protected] To unsubscribe please visit http://listserver.u2ug.org/
