Original: SQL Server replication-publish subscription (SQL Server data Synchronization)SQL Server synchronization is achieved through SQL Server's own replication tool, with 2 major strides in sub-publishing and subscription.A, copy-publishBefore publishing, you need to set several preconditions, publish properties, and snapshot locations. The main issue is to se

Now, service-oriented development has become an essential concept for b\s and c\s development, and has previously done a WCF service to invoke this service in the MVC Development mode on the Web side, which involves the replication of entity class data. Because the server-side model and the model in MVC are theoretically scoped differently, when you get the data

Disclaimer: This is a reference to Secooler's "Data Migration replication--network_link parameters between different users of the same database instance" (http://space.itpub.net/519536/viewspace-631571), thank you. In actual development and operation, we often encounter the need to transfer the structure and content of a schema, a tablespace, or some data tables

Database synchronization Issues1. There is a primary database server A and another database server B, the client first accesses database B, when the B database server is hung up to access a, when DML operations on database B, while the A is updated, if the communication between A and B fails, the updated data is stored in the temporary table, when the communication is resumed, Automatically update and delete the temporary

1. Basic Steps for copying It takes only three steps to create a simple copy. Configure a server as the Master database, that is, the Master database. Configure another server as the slave database, that is, the slave database. Connect the slave database to the master database. 2. Configure the master database To configure the server as the master database, make sure that the server has an active binary log and a unique server ID. This binary log stores all

option automatically turns off the lock table functionDo not know the translation is right, make a look at it ~ ~Simply put, is the master-slave replication in the full amount of backup, this option can automatically help us lock the table and identify the Binlog critical file, we do not need to lock the table, then look at the critical file number, and then perform the change Master fills in the Binglong location information from the library Master.

Enables replication of complex linked lists.Because each node in a complex list has a pointer to any node. So when it comes to determining the replication of this list. We need to make space in exchange for time efficiency. Then we can combine the linked list copy items in the split.That's the idea.I give the code directly:#pragma once#includeThis article from "Left Egg June" blog, reproduced please contact

The reason for the data delay of mysql replication slave server and the inherent cause of the solution delay is that the master server has two threads from the server, but it can only be executed in a single thread sequence, and there are also network latency and other reasons. Cause of delay: the master server can execute in parallel with multiple threads, but the slave server cannot execute in parallel be
