Hello, I am evaluating tools that capture and replay real database workload for benchamarking and upgrade functionality testing; mostly for 9i to 10g upgrade testing. I have never seen a tool that can reproduce database workload; and at first glance simulation is complex; given issues like intercepting all statements that are issued by connected sessions; co-ordinating the request timing for multiple sessions; handling the response data, etc. Tricky. I am not clear on how it works; whether it snoops on processes at the unix level, or logs into the database and trawl v$sql. I came across this : http://www.exact-solutions.com/products/ireplay which is related to iWatch, which seems to have been around for a while. Has anyone use iReplay? Does it do what it says on the box? Thanks!
