You want to investigate Real Application Testing. Sent from my iPhone On Nov 21, 2010, at 3:03 PM, "Ed Long" <rdhm99a@xxxxxxxxxxx<mailto:rdhm99a@xxxxxxxxxxx>> wrote: Hi everyone. I've been tasked with doing a performance improvement project for a 3rd party application. We presently lack meaningful Jmeter/Loadrunner simulations to use as a driver. Instead, the custom has been to use two in house implementations as real time benchmarks, effectively using the lower priority workloads as guinea pigs. These applications use WebSphere and Tomcat as application servers. So, my question to the group, is there a function or feature within Oracle 11G that I could use to intercept the DML and then replay it later on an experimental system? Once we do the improvement on Oracle we then have to redo it on DB2. Think time is important. It is possible that our only recourse will be to develop scripts but I will have to dot a lot of I's and cross some t's to justify that. Thanks for your kind indulgence.
