Database mirroring can be used in conjunction with replication to improve availability for the publication database. Database mirroring involves two copies of a single database that typically reside on different computers. At any given time, only one copy of the database is currentl...
Unlike replication, which works at the logical level, database mirroring works at the level of the physical log record. Beginning in SQL Server 2008, the principal server compresses the stream of transaction log records before sending it to the mirror server. This log compression occurs in all...
The database mirroring for replication is documented @ https://msdn2.microsoft.com/en-us/library/ms151799.aspx One important point you should not is that for database mirroring to work, you should be running SQL Server services under a domain account (by default it is under LOCAL SY...
The great advantage of using the database mirroring support built into ADO.NET and the SQL Native Client driver is that you do not need to recode the application, or place special code in the application, to handle a database mirroring failover.If you do not use the ADO.NET or SQL Nati...
(For more information, see "Database Mirroring and Replication" in the Implementation section later.) Client-side Redirect In SQL Server 2005, if you connect to a database that is being mirrored with ADO.NET or the SQL Native Client, your application can take advantage of the drivers' ...

1、Clustering vs. Witness AlwaysOn必須架設在Windows Cluster(WSFC)上,而如果Database Mirroring要作到Auto Failover時,就必須有第三台進行監控,也就是Witness的角色,就兩者相比由於Cluster必須要有特定硬體支援,而Witness的電腦只需要非常簡單的配備與SQL Server Express的版本就好,但是由於WSFC在節點偵測上(Heartbeat...
A larger database size means more logging, which can impact the performance of transactional replication, log shipping, and database mirroring, for example. A smaller database may be preferable over a larger one. But how can the database size be reduced? And what is the impact of a smaller...
