intern() is an interesting function in java.lang.String object. intern() function eliminates duplicate string objects from the application and has potential to reduce overall memory consumption of your application. To understand how string intern() function works you may refer to this interesting blog. Intern strings are stored in a string pool in the JVM memory. JVM Memory has following regions:

When you tune Garbage collection performance, you are not only improving Garbage collection pause time but also the overall application’s response time and reducing cloud computing cost. Recently we helped to tune the Garbage collection behavior of a popular application. Just by making a minor change, it resulted in a dramatic improvement. Let’s discuss this garbage collection tuning success story in this post.

Analyzing garbage collection log provides several advantages like: Reduces GC pause time, reduces cloud computing cost, predicts outages, provides effective metrics for capacity planning. To learn about the profound advantages of GC log analysis, please refer to this post. In this post let’s learn how to analyze GC logs?

When the application’s memory is under-allocated, it will result in the following side-effects:
a. Transactions response time will degrade
b. CPU consumption will spike up
c. OutOfMemoryError will be thrown
Only when OutOfMemoryError is thrown, most of us start to look at our application’s memory settings. This is like only when a patient goes to a critical condition; we begin to give treatment :-).
In this post, let’s discuss how to detect whether your application’s memory is under-allocated or not in a proactive manner.

As the author of GCeasy – Garbage collection log analysis tool, I get to see few interesting Garbage Collection Patterns again & again. Based on the Garbage collection pattern, you can detect the health and performance characteristics of the application instantly. In this video and the post, let me share few interesting Garbage collection patterns that have intrigued me.
