Introduction: fastThread is a fine thread dump analyzer, having all the basic features required to analyse a simple as well as a complex thread dump. It is an online open-source tool and can be accessed via URL. Basically, fastThread comes under the analysis tool category and is majorly used for performance engineering to find out the exact … Read more
There are several thread dump analysis tools are available to carry out the investigation on Threads and find out the root cause of the issue. Out of those, I found 2 thread dump analysers which are really good. Thread Dump Analysis Tools: To understand the thread dump analysis practically, we will use the ‘fastThread’ tool. We … Read more
Before discussing the type of garbage collector, it is important to understand some basic terms related to it. Type of Garbage Collector: 1. Serial GC: Serial GC is designed for single-threaded environments. It uses just a single thread for garbage collection. As a result, this GC implementation freezes all application threads when it runs. This leads … Read more
A Garbage Collector is a Java program which tracked the referenced (live) objects and allowed them to keep in the heap memory whereas the memory of the unreferenced (dead) objects is reclaimed and reused for future object allocation. To understand it more practically we have to take some pictorial examples of JVM object creation and management cycle. Let’s … Read more
What is Memory Heap? A heap is a portion of memory which is used for dynamic allocation. The blocks of the memory in the heap are frequently allocated and freed based on the status of the object. The allocation and release of memory take place in an arbitrary order and hence the unreferenced or dead … Read more
A Garbage Collector is a Java program which tracked the referenced (live) objects and allowed them to keep in the heap memory whereas the memory of the unreferenced (dead) objects is reclaimed and reused for future object allocation. This method of reclaiming unused memory is known as Garbage Collection. In Garbage collection, neither the explicit deletion of … Read more
