Transferred from: http://javis163.iteye.com/blog/1679059When using the CMS collector, the collection process for the old generation is as follows when the collection is started:1, first the JVM decides what time to start garbage collection according to-xx:cmsinitiatingoccupancyfraction,-xx:+usecmsinitiatingoccupancyonly;2, if the-xx:+usecmsinitiatingoccupancyonly is set, then the CMS GC will only be triggered if the old generation occupies exactly the

A monitor in front of the monitoring is defective, this article uses jmeter4.0+ version, using plug-in Sshmon Samples collector to do resource monitoring1. Download the plugin: Plugins-manager.jar, then put it in the Lib/ext directory and restart the jmeter.2. Open options--> Plugins Manager, tick Sshmon Samples Collector in the "Available Plugins" column and click Apply Change and Restart Jmeter3. The use

In the various parts of the Java Memory Runtime area: Program counter, virtual machine stack, local method stack with line generates and off,For the heap and method extents in Java, which objects will be created only while the program is running, this portion of memory allocation and recycling is dynamic, and the garbage collector focuses on this part of memory.What memory needs to be recycled?When do I recycle?How to recycle?The garbage

, objects that can be used as GC roots include the following:1) The object referenced in the virtual machine stack (local variable table in the stack frame);2) The object referenced by the class static property in the method area;3) The object referenced by the constants in the method;4) The object referenced in the local method by JNI (that is, the general native method).Reference definition in Java: If the value stored in the data of the reference type represents the starting address of anothe

A few days ago to do a novel series of procedures, because of the fear of updating trouble, incidentally wrote a collector, collection eight Chinese network, the function is relatively simple, can not customize the rules, but probably the idea is inside, custom rules can be extended by themselves. Use PHP to do the collector mainly use two functions: file_get_contents () and Preg_match_all (), the former i

Any language that creates objects in the process of running it means that they need to allocate space in memory for these objects, and when those objects lose their meaning, they need to be freed up to make sure that the memory is available to the new object. The release of object memory is a garbage collection mechanism, also called a GC, for Java developers, GC is a double-edged sword. We've got two funny pictures here to show the C-language garbage collection and Java garbage collection. Note

that are accessible from the root node, then move all objects to one end, and then clear out the memory benefits beyond the bounds: no memory fragmentation Disadvantage: The object is moved on top of the tag, the cost is relatively high, The efficiency is also not high 4.

The collector, usually called the Thief program, is mainly used to crawl other people's web content. About the production of the collector, in fact, is not difficult, is to open the Web to be collected remotely, and then use regular expressions to match the required content, as long as a little bit of the basis of regular expression, can make their own collector.

Read the "Deep Understanding Java Virtual Machine" Art Chapter III, "Garbage collector and memory allocation strategy", to copy the important concepts in this chapter for subsequent memory and understanding.In the heap, where almost all of the object instances in the Java world are stored, the first thing the garbage collector can do before reclaiming the heap is to determine which of these objects is "aliv

The following problems can be found in the implementation of the stylistic file grouping summary directly in Java:1. The file is not a database and cannot be accessed with SQL. When grouping and summarizing expressions change, you can only rewrite the code. To realize the flexible expression, it is necessary to implement dynamic expression parsing and evaluation, and the programming work is very large.2, the traversal process records the results of grouping, the result is small can also exist in
