Abstract This article introduces the working principle of the JDBC-based database connection pool, describes the transaction processing and multi-database servers of the connection pool technology. Various key technologies propose an efficient connection pool management policy. At last, the specific implementation process of the database connection

The role of the thread pool: The thread pool function is to limit the number of threads executing in the system.According to the environment of the system, can automatically or manually set the number of threads to achieve the best effect of the operation, less waste of system resources, many caused the system congestion efficiency is not high. The thread pool co

1. For the ASP. NET database connection pool, you can use a group of name-value pairs to configure the connection pool as a link string. For example, you can configure whether the pool is valid (which is valid by default). The maximum and minimum capacity of the pool is used for the time when the queued requests that o

What does the 1 thread pool do?Network requests usually have two forms:First, the request is not very frequent, and each connection will remain for a considerable period of time to read data or write data, and finally disconnected, such as file download, network streaming media.Another form is frequent requests, but the connection is disconnected after a small amount of data is read/written. Given the concurrency of the service, if each request comes

Design | data | database | database connection Pick to beThis paper introduces the working principle of database connection pool based on JDBC, expounds the key technologies such as transaction processing of connection pooling technology, multi database server and so on, puts forward an efficient connection pool management strategy, and finally details the implementation process of database connection

. However, for today's Web applications, especially large e-commerce websites, it is normal that hundreds or even thousands of people are online at the same time. In this case, frequent database connection operations will inevitably occupy a lot of system resources, and the website's response speed will inevitably decrease, which may even cause server crashes. This is a technical bottleneck restricting the development of some e-commerce websites. Second, each database connection must be closed a

Definition What is a thread pool? To put it simply, the thread pool is a bunch of threads that have already been created. Initially, they are all in the idle waiting state. When a new task needs to be processed, take an idle waiting thread from this pool to process the task. When the processing is complete, the thread is put back into the

Simply put, if an application needs to create and destroy threads frequently, and the task executes in a very sho

1. Why does it take a lot of time to create and initialize new objects using the object pool technology. In the initialization of such objects, if you rely on rpc Remote calls to create objects, such as connecting to remote service resources through socket or http, the most typical is the database service and RemoteQueue ), establish a connection 1. Why does it take a lot of time to create and initialize new objects using the object

I 've been watching nginx over the past few days and found that pool exists in all the places where I have memory application. Let's take a closer look. The original pool type is ngx_pool_t, which is used by nginx for memory management, so I decided to look at his implementation. 1 nginx memory pool-related struct Ngx_pool_t is defined in core/ngx_palloc.h ngx_pa

Set and view the shared pool size:In 9i, we use the Shared_pool_size parameter to set the size of the Shared Pool. Let's talk about the setting in 10 Gb. In 9i or 10g, the value of Shared_pool_size does not necessarily represent the true size of the Shared

In Java development, sometimes encountered multi-threading development, directly using the thread operation, the performance and maintenance of the program is a problem, using the Java provided by the thread pool to operate can be a good solution to the problem.The disadvantage of new threadPerform an asynchronous task are you still just following the new thread?New Thread (New Runnable () { @Override public void Run () { //todo auto-ge

The Boost library is a portable open-source C ++ function library. Given that STL (Standard Template Library) has become an integral part of the C ++ language, it is no exaggeration to say that, boost is currently the most influential universal C ++ library. The Boost library is initiated by members of the C ++ Standards Committee Working Group. Some of the content is expected to become the content of the next-generation C ++ standard library and is a quasi-standard library.The Boost memory
