spool audit.log

select name || '=' || value from v$parameter where name like '%audit%'
---"if auditing is disabled then issue this command and bounce"
alter system set audit_trail=db,extended scope = spfile
shutdown immediate
startup
create tablespace ORDER_DATA datafile '+DDATA' size 50m;
create user INFO identified by INFO;
Grant connect,resource to INFO;
Alter user INFO quota unlimited on ORDER_DATA;
create table INFO.ORDER as select * from sys.aud$;
alter INFO.ORDER add db_unique_name varchar2(50);
create table INFO.ORDER
partition by range (Timestamp#)
subpartition by hash(dbid)
subpartition template
(subpartition sp1 tablespace users,
subpartition sp2 tablespace users)(
partition p1 values less than (TO_DATE('07/29/2010','MM/DD/YYYY')),
partition p2 values less than (TO_DATE('07/29/2011','MM/DD/YYYY')),
partition p3 values less than (MAXVALUE)) tablespace BGORDER_DATA as select * from sys.aud$
spool off;
