查詢Oracle中正在執行和執行過的SQL語句

查詢Oracle正在執行的sql語句及執行該語句的用戶

SELECT b.sid oracleID,
    b.username 登錄Oracle用戶名,
    b.serial#,
    spid 操作系統ID,
    paddr,
    sql_text 正在執行的SQL,
    b.machine 計算機名
FROM v$process a, v$session b, v$sqlarea c
WHERE a.addr = b.paddr
  AND b.sql_hash_value = c.hash_value

其它網友給出的正在執行的sql語句代碼

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 '2016-10-1/09:24:47' and
    '2016-10-1/09:24:47' order by b.FIRST_LOAD_TIME

（此方法好處可以查看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 

查看正在執行sql的發起者的發放程序

SELECT OSUSER 電腦登錄身份,
    PROGRAM 發起請求的程序,
    USERNAME 登錄系統的用戶名,
    SCHEMANAME,
    B.Cpu_Time 花費cpu的時間,
    STATUS,
    B.SQL_TEXT 執行的sql
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

查出oracle當前的被鎖對象

SELECT l.session_id sid,
    s.serial#,
    l.locked_mode 鎖模式,
    l.oracle_username 登錄用戶,
    l.os_user_name 登錄機器用戶名,
    s.machine 機器名,
    s.terminal 終端用戶名,
    o.object_name 被鎖對象名,
    s.logon_time 登錄數據庫時間
FROM v$locked_object l, all_objects o, v$session s
WHERE l.object_id = o.object_id
  AND l.session_id = s.sid
ORDER BY sid, s.serial#;

kill掉當前的鎖對象可以為

alter system kill session 'sid， s.serial#‘;

查找前十條性能差的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 ; 

查看占io較大的正在運行的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
