Reference Database Link string: View the application pool usage:Select * From sysprocesses where dbid = db_id ('database name ') Max pool size: If not set, the default value is 100, and the theoretical maximum value is 32767. The maximum number of connections is the maximum number of connections that can be applied by the connection pool. If the number of datab

In-depth exploration of Java constant pool and java constant pool Java constant pools are generally divided into two types: static constant pools and runtime constant pools. Static constant pool: constant pool in the class file. The constant pool in the class file contains t

Java thread pool and java Thread Pool The cost of starting a thread by the system is relatively high because it involves interaction with the operating system. The advantage of using the thread pool is to improve performance. When the system contains a large number of concurrent threads, the maximum number of threads in the thread

Java thread pool-asynchronous task, java thread pool asynchronous 1. simple and crude thread The most primitive method: when we want to execute a task in parallel or asynchronously, We will directly start a thread, as shown below: New Thread (new Runnable () {@ Override public void run () {// TODO Auto-generated method stub here put the method you want to execute}). start (); However, there are many drawba

Java thread pool technology, java Thread Pool 1. How is the thread pool implemented?Introduction: multithreading technology mainly solves the problem of multiple threads in a processor unit. It can significantly reduce the idle time of the processor unit and increase the throughput of the processor unit.Assume that the time required for a server to complete a tas

Implementation principleWhen the database connection pool is initialized, a certain number of database connections are created in the connection pool, and the number of these database connections is constrained by the minimum number of database connections. Regardless of whether these database connections are being used, the connection pool will always be guarant

Python process pool: multiprocessing. pool, This article goes to workshop. When using Python for system management, especially operating multiple file directories at the same time, or remotely controlling multiple hosts, parallel operations can save a lot of time. When the number of objects to be operated is small, you can use the Process in multiprocessing to dynamically generate multiple processes. A doze

Using the large poolUse large pool Unlike the shared pool, the large pool does not have an LRU list. Oracle does notAttempt to age objects out of the large pool.Unlike the shared pool, the large pool does not contain the LRU list. Oracle will not try to put objectsRemove f

MYSQL thread pool summary, mysql Thread Pool Thread pool is a core function of Mysql5.6. For server applications, high concurrency requests are always a topic that cannot be bypassed, whether it is web Application Service or DB service. When there are a large number of concurrent requests for access, resources must be created and released continuously, resulting

Java thread pool (1), java Thread PoolWhy use a thread pool? 1. reduce resource consumption. Reuse created threads to reduce the consumption caused by thread creation and destruction. Second, increase the response speed. When a task arrives, the task can be executed immediately without waiting for the thread to be created. Third: Improve the manageability of threads. A thread is a scarce resource. If it

destruction are irrelevant to the work originally executed by the creation thread. To improve efficiency, Windows provides the thread pool concept. The thread pool makes it easier to create, manage, and revoke threads. I think the thread pool can be:* Initialize the thread and dynamically create the thread.* Pre-allocated thread

Analysis of Database Connection Pool (2), analysis of Database Connection Pool In the previous blog, I briefly introduced the connection process and resources consumed by common databases, and briefly discussed the connection pool, in this article, we will mainly look at the use of the database connection pool and

Thread Pool data structure and thread Construction Method As we have seen the source code of ThreadPoolExecutor, we can easily see the data structure of the ThreadPoolExecutor thread pool. Figure 1 describes the data structure. Figure 1 ThreadPoolExecutor Data Structure In fact, even if the data structure of ThreadPoolExecutor is not described in the preceding figure, we can guess its data structure accord

Java Virtual Machine: runtime volume pool, Java Virtual Machine volume pool1. Introduction to the runtime frequent pool Runtime Constant Pool, which is part of the method area. In addition to the description of the version, field, method, and interface of the Class, the Class file also contains the Constant Pool Table

Implementation Principle When the database connection pool is initialized, a certain number of database connections are created into the connection pool, which is restricted by the minimum number of database connections. Regardless of whether or not these database connections are used, the connection pool will always ensure that there are at least as many connec

Independent Thread Pool As we discussed last time, there is a CLR thread pool in A. NET application. You can use the static method in the ThreadPool class to use this thread pool. We only need to use the QueueUserWorkItem method to add tasks to the thread pool, and the thread pool
