MSSQL合并复制：极致运维体验（mssql 合并复制）

Merge replication is a SQL server feature that allows data to be synchronized between multiple databases. It is a powerful tool that can be used to efficiently keep a production environment in sync across multiple servers, while deducting most of the manual work and headaches associated with manually copying and maintaining data in multiple locations.

Merge replication combines the best of both worlds – the strong data security of a one-way replication process and the bi-directional data synchronization of a two-way replication process. With merge replication, any data that is modified in one database is replicated in all other databases so that all databases contain the same data. This ensures consistency across the databases and allows you to maintain the data in one place.

Merge replication begins with a snapshot of the source database. This is the first time that the source data is copied to the destination database. There are several options available to determine how frequently the snapshot should be taken. After the initial snapshot is complete, the database is constantly updated with any changes that are made to the source database.

The biggest advantage of merge replication is that it eliminates much of the manual intervention that is usually required to keep databases in sync. Merge replication keeps the databases in sync at all times, eliminating the need to manually copy data between them. For example, if a table in the source database is modified, the changes are automatically propagated to the other database, saving time and effort.

Another advantage of merge replication is its flexibility. Merge replication allows database administrators to specify how often the replication should take place and to which databases the changes should be propagated. This flexibility allows for granular control over when and where the data is replicated, so that it can be tailored to best suit a companies’ specific requirements.

To create a merge replication from the command line, use the SQL Server Merge Agent, which requires a few simple parameters. The parameters specify the source database, the destination database, and the replication schedule. Once the Merge Agent is created, it will run at the specified intervals and keep the databases in sync.

Merge replication is a powerful tool that allows database administrators to keep their production environments in sync in a very efficient manner. It eliminates the need to manually copy data between databases and provides flexibility to tailor the replication process to best suit a company’s requirements. In the end, Merge replication provides an excellent way to ensure that the data in each database is up-to-date and consistent.
