Are there any tools for performance testing of mainframe applications? I am not too sure at this point, what needs to be tested on a mainframe for the performance, would like to research based on the tools available and dig deep. One tool that I have heard is from Compuware.
LoadRunner supports the creation of RTE (Terminal Emulation) users for TN3270 and Telnet which are the likely candidates for commuication with your mainframe. Since this is your first project with this interface it is recommended that you seek out someone who has used this interface before and is conversant with its capabilities and limitations. You should also find someone to use as a mentor who is familiar with the monitoring peculiarities associated with monitoring of a mainframe using standard performance testing tools.
