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.
