and filter them out. The MySQL solution is too coupled with the MySQL configuration. it is easy to cause problems in the large-scale deployment of online production systems due to incorrect MySQL configuration. Custom tag SQL solution To decouple the MySQL configuration, you can consider a general markup SQL solution. To put it simply, a special mark SQL sta

, it is not necessary to allow subscribers and publishers to maintain a permanent connection because of the long delivery interval between neighboring two replicated data. Another unique feature of transactional replication is the support for parallel snapshot processing, which is also a new feature of SQL Server 2000 transactional replication. As described in t

incorrect ??!~~ After searching on the Internet, it is found to be a BUG because: This problem occurs because Log Reader Agent does not copy the transactions that are marked for replication from the transaction log into the distribution database. log Reader Agent cannot read past a specific log sequence number (LSN ). this specific LSN represents the last LSN that has been hardened to the transaction log

The company uses the Master-slave structure, on the concrete study under, here records the related content. The benefits of replication Read-write Detach: The primary database is responsible for writing and update data and reads from the databaseData security: Because data is replicated to and from the library, and you can stop the replication process from the

maturity and success stories. The principles of such products are basically the same. The working process can be divided into the following processes: Use independent processes outside of Oracle to capture redo log file information, translate it into SQL statements, and then transmit it to the target Oracle database through the network, and execute the same SQL

problems, I converted the table engine of the database from MyISAM to the table of the InnoDB engine. DRBD + Heartbeat + MySQL refer to the previous working documents and the setup was successful. The error 1062 was reported when the replication environment was set up. The detailed process is as follows:In the initial stage, refer to the MySQL manual for operations. Take the snapshot backup of the master m

) rather than responding to the row's final data change. The publisher has a large number of INSERT, update, and delete activities. The Publisher or subscriber is not a SQL Server database (for example, Oracle). By default, Subscribers to transactional publications should be treated as read-only because changes will not propagate back to the publisher. However, transactional

location are recorded in the master-info file, so that the next request is sent to the master;4. The slave SQL thread will detect some new log Content in the relay log and parse it into executable query statements to be executed on the slave side, so as to achieve data consistency between the master and slave. Configuration method:MASTER1. Edit the master configuration file/etc/my. cnf and add the following content to [mysqld:Log-bin = mysql-bin # en

A,B bidirectional replication as a model with two replication servers SQL Server replication is divided into three categories: 1. Snapshot replication A to delete all the data from the corresponding table in B at intervals, and then Insert all into B. This approach is cl
