oracle 实时查询最耗CPU资源的SQL语句

 

1. 先通过top命令查看产用资源较多的spid号

 

2.查询当前耗时的会话ID,用户名,sqlID等:
select sid,serial#,machine,username,program,sql_hash_value,sql_id,
       to_char(logon_time,'yyyy/mm/dd hh24:mi:ss') as login_time from v$session
where paddr in (select addr from v$process where spid in ('5648612','256523'));


3. 如果上一步sql_id或者 hash_value不为空,则可用v$sqlarea查出当前正在使用的sql
select sql_text
  from v$sqltext_with_newlines
  where hash_value = &hash_value
order by piece;

select * from v$sql where sql_id=''

 

 

 

---CSDN 网友提供的----

 

SELECT sql_text
 
FROM v$sqltext a
WHERE (a.hash_value, a.address) IN
       (
SELECT DECODE(sql_hash_value, 0, prev_hash_value, sql_hash_value),
               DECODE(sql_hash_value,
0, prev_sql_addr, sql_address)
         
FROM v$session b
        
WHERE b.paddr = (SELECT addr FROM v$process c WHERE c.spid = '&pid'))
ORDER BY piece ASC
