The best way to check the GC status of the Web Application Server (WAS) in operation is to use thejstatcommand. I have explained the jstat command inHow To Monitor Java Garbage Collection, so I will describe the data to check in this article. The following example shows a JVM for which...

Returning back to Garbage Collection, there is a term that you should know before learning about GC. The term is "stop-the-world." Stop-the-world will occur no matter which GC algorithm you choose.Stop-the-worldmeans that theJVMis stopping the application from running to execute a GC. Wh...

for an application. This selection assumes that the class of the machine on which the application is run is a hint as to the characteristics of the application (i.e., large applications run on large machines). In addition to these selections is a simplified way of tuning garbage collection....
11How you can force the garbage collection? Garbage collection automatic process and can't be forced. 12What is OOPS? OOP is the common abbreviation for Object-Oriented Programming. 13Describe the principles of OOPS. There are three main principals of oops which are called Polymorphism, Inheritan...

The concurrent collector performs most of its work concurrently (i.e., while the application is still running) to keep garbage collection pauses short. It is designed for applications with medium- to large-sized data sets for which response time is more important than overall throughput, since ...
