Background documentation-3068: Mismatch of parameter configuration between backup and instance Locate this document in the navigation structure

 

Explanation

When data is backed up, the database parameters are backed up too. Before data is restored, a check is run first to see if the database parameters from the data backup are compatible with the current database parameters of the target database instance.

Example Example

A UNICODE database instance backup is not allowed in a non-UNICODE database instance.

End of the example.
User Response

The DB parameters of the target database must match the DB parameters saved in the data backup. At present, this only affects the special database parameter _UNICODE.
