Cross-row referencesEarly SQL does not directly support cross-line references, and it is extremely cumbersome to generate serial numbers and then join. SQL after the introduction of the window function makes it easier to reference other row data, but the notation is still not concise, and the code is very long when there are multiple cross-line reference items. Moreover, as mentioned above, the window function is implemented on the basis of other operation result sets, and the re-reference of th

Clever use of PHP functions to implement collectors. PHP has been developing for a long time and many users are familiar with PHP. now we can use PHP functions to implement the collector program. What is a collector? it is usually called a thief program. it is mainly used to catch PHP. after a long period of development, many users know PHP very well. now we can use PHP functions to implement the

In this article, we will talk about the relationship between the garbage collector and the virtual memory and physical memory of the program. Let's talk about how to determine whether your managed heap is healthy. Why does the program throw an OutofMemoryException when the machine has a large amount of memory. Relationship between garbage collection and physical memory virtual memory: If you know this topic well, skip this section. GC needs to allocat

CMS (Concurrent Mark Sweep) collector C:concurrent M: Tag (Marking) object: GC must remember which objects are available to delete unreachable objects S: Clear (sweeping): Remove unmarked objects and free their memory CMS is a collector with the shortest pause time, and the CMS does not achieve the highest GC efficiency, but it minimizes the downtime of the service at GC. Use the mark-purge algorithm (Mar

the objects in these areas are selected as GC roots, and the objects referenced by GC roots are not recycled by GC.　　　　If you want to refine GC ROOTS,GC Roots include:　　　　　　1, all aged with objects2, all global objects3, all JNI handles4, all Locked objectsObjects held by 5,JVMTI6, Code snippet Code_cache7, all ClassLoader, and its loaded class8, all dictionaries9,flat_profiler and Management10, most importantly, all of the reference type variables running on the thread stack. 3.

When 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 proportions set by the-xx:cmsinitiatingoccupancyfractio

The computer configuration is not high enough, and the JVM is configured on the original basis. The G1 garbage collection in jdk1.7 is occasionally seen, so it is replaced with the G1 garbage collector, which is faster than the previous configuration, in addition, eclipse does not occasionally get stuck when you do not manually click recycle (only for eclipse optimization, compilation for project reasonsCodeUse 1.6.0 _ 30 ). The original configuration

The garbage collector (garbage COLLECTOR,GC) is basically transparent to Java programmers, but a good Java programmer must understand how the GC works, how to optimize GC performance, and how to interact with the GC in limited ways, because some applications have higher performance requirements , such as embedded systems, real-time systems, can improve the performance of the entire application only if it im

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

It is not difficult to create a collector, that is, to remotely open the webpage to be collected, and then use a regular expression to match the required content, as long as there is a little basis for a regular expression, can make their own collector SyntaxHighlighter
