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

Distributed replicated Block Device (DRBD) is a software-free, shared-sharing, storage-replication solution that mirrors the contents of a piece of equipment between servers. Data mirroring: Real-time, transparent, synchronous (returned after all successful servers), asynchronous (returned after the local server succeeds) DRBD's core functionality is implemente
