Course Overview
Deep dive - Threads, Memory, JDBC pools, Dynamic caching, Session mngt, Security - for optimal WebSphere performance.
Do you want to learn how to troubleshoot JVM crashes, analyze dumps, tune memory, and optimize clusters like a true L2/L3 administrator?
This course – WebSphere Performance Tuning – L2 & L3 – is designed to take you deep into the real-world tuning and troubleshooting techniques that every middleware engineer, administrator, and support professional must master.
You’ll gain hands-on knowledge on:
Understanding and tuning threads and thread pools for different workloads.
Identifying and resolving stuck threads, deadlocks, and contention issues.
Configuring and troubleshooting Dynamic Cache Service, Replication Domains, Session Affinity, and Sticky Sessions.
Managing memory and JVM heap, selecting the right GC policies, and tuning garbage collection.
Performing thread dump and heap dump analysis to find bottlenecks and memory leaks.
Using profiler tools to detect inefficiencies and optimize application performance.
Configuring JDBC connection pools and datasources, including tuning connection pool parameters for stability and throughput.
Applying best practices for real-time troubleshooting and performance tuning in clustered WebSphere environments.
This course is filled with step-by-step demos, real-world use cases, and production-grade scenarios to prepare you for L2 & L3 support challenges.
By the end of this course, you’ll be able to:
Troubleshoot performance issues confidently in live environments.
Analyze dumps and logs to find the root cause of JVM and application slowdowns.
Tune JVM, threads, caches, and JDBC pools for high performance.
Handle WebSphere performance like an expert administrator.
