Source code analysis: HotSpot GC Process (1), hotspotgc For the garbage collection process of HotSpot virtual machines, this section analyzes and introduces the garbage collection content of MarkSweepPolicy and TenuredGeneration under the default configuration, and introduces other GC policies and GC ideas of generation implementation. The

This article on the Java Virtual Machine Memory management mechanism to explain, I feel the content is very good and clear, so the article reproduced over, I suggest that readers can calm down to read. The original address Java memory area and the GC mechanism most detailed. Here I also write my own personal understanding for the reader to refer to: When it comes to memory, for our programmers, the most I can think of is stacks and heaps. Stack Stack:

Terminology Explanation: 1. Garbage The so-called rubbish (garbage) is the object that needs to be recycled. As a writer, you can judge that "this variable is no longer needed," but the computer can't. Therefore, if the program refers directly or indirectly to an object, then the object is considered "alive", whereas an object that has not been referenced is considered "dead". It is the nature of the GC to find these "dead" objects and then recycle th

First, introduce one person: Jon Masamitsu. This person's background is unknown, but he does JVM in Sun, so his blog I think everyone who wants to tune the JVM should read it. Many of the ideas and figures in this article are also taken from his blog.Blog link: http://blogs.sun.com/jonthecollector/ In his blog [1], the three most important options for GC optimization are written:The third place is the proportion of young generation in the entire JVM h

Java GC mechanism and AlgorithmGC stageFor each object, garbage collection is divided into two stages: finalization and reclamation. Finalization: the method used to run the finalize of this object. Reclamation: reclaim the memory used by this object. Basic steps of GC Process First, make sure that the object is inaccessible and will be recycled soon. Second, if the object has a finalize method, the

This article is for WebSphere Portal version 6.0 or later (and 5.1 or later), running Java™software Development Kit (SDK) 1.4.2. For best tuning, it is recommended that you use the latest service release of the SDK to use at least one new SR13 Service release for the tuning discussed here. Garbage collection can be simply defined as JAVATM Virtual Machine (JVM) frees the heap behavior of objects that are no longer referenced or used by the process, heap refers to a predefined part of memory that

thread executes the bytecode.Java Heap memory allocation mechanismJava memory allocation and recycling in a nutshell: Generational allocation, generational recycling. The object will be divided according to the time of inventory: young generation, Old generation,permanent generation.Yong Generation: When an object is created, the allocation of memory occurs first in the younger generation (large objects can be created directly in the old generation), and most of the objects are not used immedia

Transfer from CSDNThe previous article summarizes the basic algorithm of GC, the basic principle of various GC collectors, or the concept of coarse granularity. This article will collate some of the common concepts of GC, understand these concepts, and believe in a more in-depth understanding of GC1. When will the minor GC
