I would like to know if LoadRunner can be used to execute the performance and load testing on:
1- non GUI Java applications
2- non GUI J2EE applications
3- non GUI CORBA (IDL) applications

Thanks,
Mohamed

Mohamed,
Yes, there is nothing in LoadRunner that is java specific.

Keep in mind that load runner does two things: load and monitoring for bottlenecks.

I would like to add to Jeanne's answer that LoadRunner is in fact a performance/monitoring tool and not a tool helping to test your code. It is more related to use case testing (full functionality), rather than unit testing.

Ali,
I agree with half of that statement (performance/monitoring tool). While LoadRunner can test use cases, it isn't testing for functionality. It is testing for performance. You still need some other way of testing for the right functionality.

IMO it is pretty wrong to test unit performance. As M.Fowler explained applying optimization and analysing performance on unit and not on overall solution will increase the volume of work and not always provide the solution (the 80-20 rule).

By the way, is Topaz (Mercury Interactive's service level monitoring tool) running something of its own or does it use the same "scripts" as LoadRunner?

I agree that it is not the place to start. But once you know which units are the bottleneck, it is good for before and after testing. Here the unit is usually an EJB rather than a class.
