, distributed Application system puts forward the demand for large-scale transaction processing, such as a large number of critical transactions in commercial activities. Transaction processing monitoring interface between client and server for transaction management and coordination, load balancing, failure recovery, etc., to improve the overall performance of the system. It can be seen as the "operating system" of a transactional application. In general, transaction processing monitoring has t

If two threads modify the same record in the database at the same time, it causes the latter record to overwrite the previous one, causing some problems.For example:A ticketing system has a number of votes, the client every call to the ticket method, the number of votes minus one.Scene:A total of 300 tickets, assuming that two tickets, exactly at the same time ticket, they do the operation is first check the number of votes, and then minus one.General

Take a look at an example without thread synchronization, this example is very simple, just let two threads output the same content, do not do other things, so, thread synchronization is not obvious here. Import Java.util.Date; public class ThreadTest extends thread{int pausetime; String name; /** * @param args */public static void main (string[] args) {//TODO auto-generated method stub ThreadTest tT1 = new ThreadTest (1000, "Thread1"); Tt1.s

transactional processing, supports foreign keys, supports crash-repair capabilities, and concurrency control. If you need to have high integrity requirements for transactions (such as a bank) and require concurrency control (such as ticketing), then choosing InnoDB has a big advantage. If you need frequent updates, delete operations of the database, you can also choose InnoDB, because the transaction support commits (commit) and rollback (rollback).

One: Let's consider the following solutions for several business scenarios:-The payment system runs daily at 1 o'clock in the morning and is cleared for one day, and the monthly number 1th is cleared last month. -Taobao on the hour, the price of goods 8 o'clock the start of the promotion -12306 ticketing system, more than 30 minutes did not successfully pay the order, for the recycling process -After the product has been successfully shipped, you need

you access, and the other transaction cannot update the data until the transaction releases the lock.The task of concurrency control in a database management system (DBMS) is to ensure that multiple transactions concurrently access the same data in the database without disrupting the isolation and uniformity of the transaction and the consistency of the database. The following is an example of the data inconsistency problem caused by concurrent operations:There are two tickets available at the

concurrency controlThe task of concurrency control in a DBMS is to ensure that the isolation of transactions is not broken and the consistency of the database is ensured when multiple transactions concurrently access the consolidated data in the database.Example: There are two tickets for ticket sales at the same time, while reading a train ticket in the database, the ticket balance is X. Two ticketing points sell a ticket at the same time, while the
