java remote profiling

Remote debugging is useful for application development. For example, a low-end machine developer that cannot host a development platform, or a debugger on a dedicated machine, such as a WEB server where a service cannot be interrupted. Other scenarios include Java applications that run on devices with low memory or CUP performance, such as mobile devices, or developers who want to separate applications from

One of the most fundamental issues in a distributed service framework is how remote services communicate, and there are many technologies in the Java domain that enable remote communication, such as RMI, MINA, ESB, Burlap, Hessian, SOAP, EJB, and JMS, What is the relationship between these nouns? What exactly are they based on, knowing that these are the basics o

Web development is so good, HTML is used so much, mainly because of convenient deployment and fast updates. The disadvantage of applications is the complexity of updates. Through this article, the application can be deployed as easily as the web. Easy to use. As mentioned in the previous article, Java programs only rely on bytecode. Modifying the class file read/write mode can implement code encryption. The so-called "bytecode" is only a byte sequenc

Java RMI refers to remote method invocation (invocation). It is a mechanism that enables an object on one Java virtual machine to invoke a method on an object in another Java virtual machine.Any object that can be called with this method must implement the remote interface.

Starting with Java 5, the JDK provides some API for JVM detection, which is known as the Java.lang.management package, which provides many Mxbean interface classes that can be easily retrieved to the JVM's memory, GC, Thread, lock, class, Even the operating system level of various information, this article is a simple introduction of the use of JMX on the Java process CPU, heap memory usage monitoring. Some

I. Summary This article compares the transmission performance of five communication protocols, including RMI, Hessian, burlap, httpinvoker, and Web Service, in different data structures and data volumes. RMI is a remote communication protocol provided by the Java language. It is stable and efficient and is the basis of EJB. But it can only be used in Java Progra

Java VisualVM monitors remote JVM and javavisualvmjvm We often need to perform various tests on the software we developed, and the use of the software to system resources is even more indispensable. Currently, there are multiple monitoring tools, compared with JProfiler, which consumes a lot of system resources, especially memory, JDK1.6 comes with VisualVM, which is a good monitoring tool.This tool is loca

We often need to do a variety of testing of our development software, software use of system resources is not limited , there are a number of monitoring tools , compared to jprofiler system resources, especially memory consumption is very large, JDK1.6 began to bring the VISUALVM is a good monitoring tool.This tool is in the java_home\bin\ directory of the Jvisualvm.exe, double-click the file will be able to see a more intuitive interfaceAs you can see from the left applications tree, you can mo

RMI is a set of Java APIs that support the development of distributed applications. RMI defines a remote object using the Java language interface, which aggregates the Java serialization and Java Remote Method Protocol (

The Jconsole is a graphical tool introduced from Java 5 to monitor JVM performance and resource consumption. The Jconsole can connect to a local Java program or to a remote Java program.
