I've set the heap size to 512MB, and over time the app runs out of memory. Unfortunately I haven't much time to learn the Resource Analyser or the monitoring/logging that is part of Websphere. Which tool is the best place to start to diagnose this problem?
Are you using WSAD? Then use their profiling tool to figure out how is your heap behaving. I will go with 256 min heap size and 256 max heap size to do this performance testing.
Drove my Chevy to the levee but the levee was dry. A wrung this tiny ad and it was still dry.
