Hi, I was thinking in a tools that capture and replay real database workload for benchmarking and upgrade functionality testing; I have never seen a tool that can reproduce database workload, however I just heard about a tool called iReplay. Probably its a payed tool, so I was considering the mechanism that does that, what to consider and so on. Does anyone know any other tool (preferably free) that does that or similar. Its a point that I consider starting to develop a tool (free) to do that, but I have no idea which mechanism consider. Any clue is more than welcome. Thank you. Alex
