SQLServer2008 is able to see the subscription to Oracle or DB2 when the subscription is being placed, but there is no indirect interface for copying to MySQL.The end of the test, through MySQL ODBC driver, is able to implement the SQLServer2008 copy to MySQL, thus implementing the schema from the library is SQL Server, read-only library for MySQL.Firstly, a general distribution and release database is requi

But I think this feature is also useful for setting up a backup server or a test server. On a single machine to publish services, you can subscribe to other machines in the SQL, according to your release of different conditions, you can make a timed synchronization, real-time synchronization, synchronization and other different publications and subscriptions.

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 publishe

In this example, there are two major special features; any sales Manager or sales backbone can modify the sales informa

In this dialog box, you can find out what the Snapshot Agent has done so far, and how long it has been running. Summary of this chapter This chapter focuses on t

Further discussion of its principle and configuration is discussed later. 4.Mirror Mirror is a powerful high-availability scenario provided by SQL Server 2005. Its mirror database cannot be read directly, which is not in accordance with our requirement scenario, so it is no longer. 5.Integration Service The integrati

In this section we will compare the basic functions of these four technologies and then delve into how to supplement or provide a better solution for database mirroring.
