Load simulating

Hello,
The Environment Im working is based on UNIX and Oracle.

 1. Is it possible to simulate a workload change (more transactions, more concurrent users, less CPUs,....) with no extra tools, only scripts (how).

 2. If not, what is the best product to get simulating the existing production systems workload.

My best regards
Aly ELMarsafy

LoadRunner will do the job - trust. We have been using it on a massive scale on a huge project here in the UK, and it is definately the tool for the task.

Its not a Web Based application, rather its mainly the DWH, the Billing application, and other UNIX  tools.

So, Im going to try that Loadrunner to simulate an increase in the number of users, transactions, ....

Note: Does it simulate a change in the hardware specifications!

Apache has a new tool called JMeter.  You have the ability to customize several parameters including simulated users, # of concurrent connections, how often the connections are made and so on.  Best of all, it is OpenSource and freely available for use.  It may be obtained from www.apache.org
