Dbvisit Replicate communicates with both source and target database to replicate data. This communication includes reading and writing data through Data Source Name (DSN) configured using ODBC data source and drivers. A DSN for SQL server on source system is required by Dbvisit Replicate to successfully execute configurational scripts that prepares the target MSSQL environment for replication. On target system, a DSN with same name as source system is required by the APPLY service which interacts with target database to replicate changes of source database.
