_Error while creating a session

Question

While i was creating a session i got an error. My syntax was ..
create schema AUTHORIZATION aijazdb
CREATE TABLE paint
(paint_id NUMBER PRIMARY KEY,
paint_size NUMBER,
colour VARCHAR2(10) )
CREATE VIEW large_paints AS
SELECT paint_id,colour FROM paint WHERE paint_size=100
GRANT select ON large_paints TO aijazdb;
*** ERROR
create schema AUTHORIZATION aijazdb
ERROR at line 1:
ORA-02421: missing or invalid schema authorization identifier
1.) First of all why do we use Authorization keyword while creating a schema.
2.) And what is reason for such error.

Answer 1

This is Metalink Support document note which you can access if you have a valid (and paid) support services license. About the error,
>
ORA-02421:
     missing or invalid schema authorization identifier
Cause:      the schema name is missing or is incorrect in an authorization clause of a create schema statement.
Action:      If the name is present, it must be the same as the current schema.

This is what error description says. So now you may want to tell us that how did you create the user, I mean by which command and what privs you assigned to him afterwards?
