However, I think this function is also useful for setting backup servers or testing servers, Publishing Services on one machine can be subscribed to in the SQL statements of other machines.

Suppose you want to test the data in a production environment, such as modifying and testing stored procedures, changing and optimizing indexes, and so on. But if your users are connected to the database, you cannot disconnect the database. How do I get a copy of the database?I. Using the Copy Database menu in a database taskThe example is to copy the Northwind database from the default instance MSSQLSERVER to the named instance MySQLServer. Open the service as follows:Figure ANext, we'll fight.

ReplicationMysql> set global rpl_semi_sync_slave_enabled = on;Query OK, 0 rows affected (0.00 sec)Rpl_semi_sync_master_enabled and rpl_semi_sync_slave_enabled can also be configured in the master and slave configuration files, so that the server restart will take effect.In this way, the configuration of a semi-synchronous replication is complete. After configuri

The SQL Server replication divides large transactions into small transaction distribution methods. In SQL server replication, when a large transaction is executed in the published database, for example, 100,000 or more data is ope

server| Create We know that SQL Server 2000 's merge replication supports dynamic filter functionality. If we have multiple subscriber, each Subscriber only needs to maintain its own specific data, we simply create a publication and then take advantage of the function of dynamic filter, Copy the specific data that each

In the previous article, SQL Server 2005/2008 merged and copied step by step.ArticleThe text explains how to use SQL Server's replication function step by step. If the replication test is performed on the same machine (the same machine is both a publisher and a subscriber),

not enabled, or switches to asynchronous replication state The Rpl_semi_sync_slave_status state on the slave, 1, indicates that it is enabled and I/O threads are running, and 0 indicates an inactive state. Several questions to consider when using semi-synchronous replication: 1, when all the slave crashes, how does the state of the semi

Q: How to copy the structure of other tables into a specified table, such as the following example:The following three tables are available:Table A: Field 1, Field 2, Field 3Table B: Field 1, Field 2, Field 3Table C: Field 1, Field 2, Field 3Now you want to copy the field of Table 1,b table field 2,c table field 3 to table 4. The data in the table is not required.How should SQL statements be implemented?A: In fact, here is a question to consider, the

after mysql5.5. Two plug-ins are available: semisync_master.so and semisync_slave.so. Semi-Sync: In a master-slave architecture, the master database only waits for one slave database to copy the data and return a normal response. This means that the synchronization is complete and the next step is implemented, that is, asynchronous and high-speed, and synchronization security. Once the master database waits for the response from the slave database to time out, semi-

The differences between MySQL semi-synchronous and asynchronous replication are as shown in the architecture diagram above: In the case of MySQL asynchronous replication, MySQL master server transfers its binary log through the replication thread, MySQL Master Sever automati
