Oracle Solution for Error ora-39779

ORA-39779: type "string

"."string

" not found or conversion to latest version is not possible

What triggered the Error:

Unable to import table data using the specified type. The type was nonexistent in the database or the input type could not be converted to the existing type. The reasons why a conversion was not possible are: *1. The version of the type in the database was greater than the version of the type at export time because 1 or more attributes have been added or dropped from the type. *2. If the type existed in the database prior to the import operation, then its internal identifier may not match the internal identifier of the type from the export database. The identifiers must match for an import to succeed.

What should we do to fix it:

Ensure the types in the database match those at export time.
