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_

---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
