A table consistency check is performed each time the Datapump application connects to the relational target.
The table consistency check imports the definition of all tables associated with class mappings for the database and checks that column names and types match those defined in the JADE schema. This consistency checking detects cases where a table definition or redefinition has not been applied or you have altered the definition of a target table for some reason, introducing a mismatch.
When a mismatch is detected, details about the mismatch are logged and the connection attempt fails. An administrative user must correct the mismatch before retrying the RPS connection.
