Can SQL Mirroring be implemented on .NET 1.1

The straight answer is NO, let me find some tweeks and update this topic.

And yes its true, for mirroring , failover implementation it need to provide the failover partner into the connection string which is not supported for .NET Framework 1.1 and 1.0.


http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.connectionstring.aspx


Key: Failover Partner
Default Value : N/A
Description: The name of the failover partner server where database mirroring is configured.
The Failover Partner keyword is not supported by .NET Framework version 1.0 or 1.1.

Database Mirroring Vs Database Replication [SQL 2005 and Above]


Database Mirroring

Database Replication

Making the same database with transaction logs [ synchronous or asynchronous]

Making the same database replicated on other server.

Only snapshot can be used to fetch the data from mirroring server.

Can be fetched data directly from the replicated server.

Mirroring is preferred when we want database online most of the time.

Replication used when we need to run the reports without affecting the primary database performance.

In case of failover the mirroring database in as primary database.

In case of failover you have to specify the secondary database name, it's not failover automatically.
