OID - If the value is specified as n, the assignment of the exported OID during the creation of object tables and types is inhibited. Instead, a new OID is assigned. This can be useful for cloning schemas, but does not affect referenced objects. The default value is y.

ORA-39083: Object type string failed to create with error: string Failing sql is: string 
Cause: Examine original error code to determine actual cause 
Action: Original error code will contain more information 


ORA-02304: invalid object identifier literal 
Cause: An attempt was made to enter an object identifier literal for CREATE TYPE that is either: 
- not a string of 32 hexadecimal characters

- an object identifier that already identifies an existing object

- an object identifier different from the original object identifier already assigned to the type
 
Action: Do not specify the object identifier clause or specify a 32 hexadecimal-character object identifier literal that is unique or identical to the originally assigned object identifier. Then retry the operation 


Hope this Helps.
