sql server synchronous replication

Manual repair of fields added in the release and subscription for replication of SQL Server against schema changes Due to previous requirements, the replication architecture changes are prohibited, and even adding a field to the release will not be synchronized to the subscription. Now, a field with the same name is ad

Monitoring SQL Server Transactional replicationIn general, we can use the Replication Monitor in SSMs to monitor replication. But we can't stare at it for 24 hours, and we have to use an automated way to monitor it. Microsoft provides system stored procedure DBO.SP_REPLMONITORSUBSCRIPTIONPENDINGCMDS in the distribution

Cause and solution of SQL Server database replication failure During database operations on SQL Server, the following error occurs during database replication. The error message is shown in: Cause and solution of

I. BACKGROUND When you build SQL Server replication, if the network environment is within the LAN, through the host name can be achieved, but if it is across the network segment, across the computer room to build replication when you need to pay attention to, because SQL

Although SQL Server 2008 has so far been considered a new version of the database system. But it will continue to update. For this reason, database administrators still need to consider backward compatibility issues when deploying SQL Server 2008. In order to reduce the problem of later upgrades, it is necessary for th

The last article on MySQL replication focuses on the design points and constraints of the two-way synchronous replication architecture. The dual-master, dual-write, and bidirectional synchronization scenarios of databases are restricted, mainly considering data integrity, consistency, and conflict avoidance. For the last article about MySQL

You might want to explore ways to take advantage of different kinds of replication for a variety of reasons, but probably the biggest reason is to allow administrators to provide SQL Servers to customers, and those customers ' companies are investing a lot in other data systems. SQL Server allows you to replicate data
