On Wednesday, October 21st at 11:00 AM ET, I'll be presenting the Top 10 Performance and Troubleshooting tips for WebSphere Application Server traditional and Liberty:
https://techtv.bemyapp.com/#/conference/5f6d07f9649cbe001b302113
This session will include a live demo showing some of these tips in action. You will have time to ask questions of the experts on the show!
Here's a sneak peek of the topics we'll cover:
Top 5 Performance tips:
Tune maximum Java heap and nursery sizes using verbosegc
Tune thread pools and connection pools
Ensure CPU, RAM, network, and disk aren’t saturated
Monitor arrival rate, response times, utilization, error rate and throughput
Aggressively use caching where possible
Top 5 Troubleshooting tips:
Gather multiple thread dumps and basic OS statistics during an issue. Collect all logs.
Use hung thread detection (tWAS) and requestTiming (Liberty) for long responses
Use a sampling profiler
For J9 JVMs, use OS core dumps instead of PHDs for OutOfMemoryErrors
Consider using the NCSA Access Log
