Dpump - Problems with object types when importing full export from version 10.2.0 to version 11.2.
I have made a full export of database 10.2.0 with a data pump and tried to import it to a newly created database 11.2.
The source database contains several user-defined object types and tables with attributes having these types and, besides, one attribute having the SDO_GEOMETRY data type.
These tables coudn't be imported producing the error ORA-39779: type "string"."string" not found or conversion to latest version is not possible. The object types were correctly defined in the target database after import.
According to the documentation the only possible cause was the problem with OID's, so I tried to use the TRANSFORM:OID:n:TYPE parameter, but the result was the same.
