Create Users Like Another User In Oracle Database

How To Create Users Like Another User In Oracle Database At SQL Command Line, Not From OEM (Doc ID 1352212.1)

Solution 1:
exec  dbms_metadata.set_transform_param(dbms_metadata.SESSION_TRANSFORM,'SQLTERMINATOR',TRUE);

select dbms_metadata.get_ddl( 'USER', '' ) from dual
    UNION ALL
    select dbms_metadata.get_granted_ddl( 'SYSTEM_GRANT', '' ) from dual
    UNION ALL
    select dbms_metadata.get_granted_ddl( 'OBJECT_GRANT', '' ) from dual
    UNION ALL
    select dbms_metadata.get_granted_ddl( 'ROLE_GRANT', '' ) from dual

    UNION ALL

select dbms_metadata.get_ddl('TABLESPACE','USER_DATA') from dual;

Solution 2:
To get the user's privileges you can query the following tables:

--  For Table privileges: DBA_TAB_PRIVS

-- For Column privileges: DBA_COL_PRIVS

-- For System privileges: DBA_SYS_PRIVS

-- For Roles:  DBA_ROLE_PRIVS


You can also use the DBMS_METADATA package:

-- For object privileges granted to a user :
SELECT DBMS_METADATA.GET_GRANTED_DDL('OBJECT_GRANT',upper('&GRANTED_USER'))
FROM DUAL;

-- For system privileges granted to a user :
SELECT DBMS_METADATA.GET_GRANTED_DDL('SYSTEM_GRANT',upper('&GRANTED_USER'))
FROM DUAL;

-- For roles granted to a user :
SELECT DBMS_METADATA.GET_GRANTED_DDL('ROLE_GRANT',upper('&GRANTED_USER'))
FROM DUAL;

The following scripts can be used to create a user identical to another user :

NOTE:
The above generated commands must be executed to actually create the new user with its privileges


-- Set Default Role...
set serveroutput on

    if length(defroles) > 0 then
      defroles := defroles||','||c1.granted_role;
    else
      defroles := defroles||c1.granted_role;
    end if;
  end loop;
dbms_output.put_line('alter user &&newname default role '||defroles||';');
