When working with database transactions, some operations can produce errors, and errors can result in unpredictable operations, especially in bulk transactions. In order to avoid this situation, it is necessary to control the data connection and handle the error information in the database transaction accordingly. 1. Database error message let's look at the error message of the database first. Here, using an Access file dbcon.accdb as the target database, in the

Tags: MongoDB script digital comparison collectorMongoDB Scripting has limited computational power to solve complex problems, and is more difficult to use directly. In many cases, it is necessary to read the data out of the main program to complete the operation, and in high-level languages such as Java to write this kind of aggregate operation is also more troublesome. This can be aided by the esproc of the collector, and the use of this method is il

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

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

In the previous article, the Java Memory Runtime area is described, where the program counter, virtual machine stack, local method stack 3 zones are born out of the thread, and stack frames in the stack are methodically executed into the stack as the method enters and exits. The amount of memory allocated in each stack frame is basically known as the class structure, so the allocation and recycling of memory in these areas is deterministic. The memory is reclaimed when the method is accepted. Ja
