Database A and Database B are built on two independent database servers. Using dblink is a feasible way. There are two data synchronization processes: First, when the database A is running normally, the data needs to be synchronized to the standby database, ie, the database B; 2. When database A is not normal, database B is enabled. Before database A recovers, data updates occur in database B. Therefore, database B needs to be synchronized to database A. The first way: the premise is that database A and database B local network are 24-hour interoperable and have high requirements for windows 7 real time file sync-time data synchronization. Then DBLINK can be established. Triggers are built in both libraries, regardless of the current library. Real-time synchronization of data to the target database when data updates occur; Database A and Database B are built on two independent database servers. Using dblink is a feasible way.
