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;
也可直接使用:
select a.*,b.SQL_TEXT from (
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 ('23226'))
) a,v$sql b
where a.sql_id = b.SQL_ID(+)
4.kill占用大资源的session
Alter system kill session 'SID,SERIAL#'
