Create Type as Object not working in linux oracle 11g

Question

Pleae refer to the following simple create type as object statement.
CREATE OR REPLACE TYPE EC_VIEWABLETYPES as object ( CASE_TYPE_ID NUMBER)
It is working in oracle 11g and windows server 2008 environment.
But it is not working in oracle 11g with linux environment.
I am executing this statement as dynamic sql as follows
CREATE OR REPLACE PROCEDURE TEMP_SP
AS

DECLARE vcType VARCHAR2(30);
BEGIN
SELECT OBJECT_TYPE into vcType FROM USER_OBJECTS
WHERE OBJECT_NAME='EC_VIEWABLETYPES' AND OBJECT_TYPE='TYPE';
EXCEPTION
WHEN NO_DATA_FOUND THEN
EXECUTE IMMEDIATE 'CREATE OR REPLACE TYPE EC_VIEWABLETYPES as object ( CASE_TYPE_ID NUMBER) ';
COMMIT;
RETURN;
END;
END;
exec TEMP_SP
