Data Source Name(s) or DSN is defined in Pervasive Control Center (PCC) in order for users to use the following functionalities in the system:
This greatly helps the improvement of speed in searching on the database of the system. Since, most of the customers are using old versions of Pervasive Database Engine (e.g. V9.5, V8, and V7), they definitely have defined their DSN’s in PCC for their datasets. In view of the fact that we need to uninstall the older versions before installing PSQL v10, previously defined DSN gets lost of the connection as well as could bring or prompt an error message: “[Microsoft][ODBC Driver Manager]Data Source Name not found and no default driver specified. Component is SQL Database, Status 51 owned by dm1” upon installation of the new version.
