---正在執行的

select a.username, a.sid,b.sql_text, b.sql_fulltext

from v$session a, v$sqlarea b

where a.sql_address = b.address

---執行過的

select b.sql_text,b.first_load_time,b.sql_fulltext

from v$sqlarea b

where b.first_load_time between '2009-10-15/09:24:47' and

'2009-10-15/09:24:47' order by b.first_load_time

(此方法好處可以檢視某一時間段執行過的sql,並且 sql_fulltext 包含了完整的 sql 語句)

其他select osuser,program,username,schemaname,b.cpu_time,status,b.sql_text

from v$session a left join v$sql b on a.sql_address=b.address and a.sql_hash_value=b.hash_value order by b.cpu_time desc

select address, sql_text, piece

from v$session, v$sqltext

where address = sql_address

-- and machine = < you machine name >

order by address, piece

查詢前十條效能差的sql.

select * from (select parsing_user_id,executions,sorts,

command_type,disk_reads,sql_text from v$sqlarea

order by disk_reads desc )where rownum<10 ;

檢視佔io較大的正在執行的session

select se.sid,se.serial#,pr.spid,se.username,se.status,

se.terminal,se.program,se.module,、se.sql_address,st.event,st.

p1text,si.physical_reads,

si.block_changes from v$session se,v$session_wait st,

v$sess_io si,v$process pr where st.sid=se.sid and st.

sid=si.sid and se.paddr=pr.addr and se.sid>6 and st.

wait_time=0 and st.event not like '%sql%' order by physical_reads desc

select t2.username,t2.sid,t2.serial#,t2.logon_time 

from v$locked_object t1,v$session t2 

where t1.session_id=t2.sid order by t2.sid,t2.logon_time;

select sql_text from v$session a,v$sqltext_with_newlines b

where decode(a.sql_hash_value, 0, prev_hash_value, sql_hash_value)=b.hash_value

and a.sid=112 order by piece
