OK we have an RS/6000 running AIX - of course - and we have a program called Bizflow running on it - I would like to test a load on the server to simulate more users on the box/hitting the box - maybe even logging on to the program - something to that effect -
I just want to make sure that the box can handle the load - of a lot of users up to 1000 - but right now 50 - 100 would be fine -
anyway - I hope this is clear - if not you know where i am at -

You could try writing a C-program, but depending on the construction of the Bizflow application, this may give false results. You could try a shell script, but again - it may give false results.
Without knowing the architecture of the application (language written in, original platform, etc...), it will be quite difficult to generate something yourself; you need to mimic exactly how the program allocates memory, handles disk I/O, stores user spaces ... ... ... and on and on.
Unfortunately, there is no simple canned solution for something like this. You can look at TPCC numbers, but I don't put alot of value in them.
Contact your vendor and see if they have a load tester or a "hardware compatability listing". With SAP, they have a worksheet that you can fill out with the needs you have (# of users, expected response times, etc) and the hardware platform you intend to use - and they run it through a magic program and come up with a hardware recommendation.
Every application is different, so to come up with a benchmark application - this would be quite difficult.
Good luck, Bill.
