ORA-1652错误 unable to extend temp segment by 128 in tablespace

周六下午，收到EM alert邮件

Sfc12db 的TEMP 表空间使用率达到99% 查看alert log

在alert log中有 ORA-1652错误 unable to extend temp segment by 128 in tablespace 。

用如下语句可以查询到是什么程序大量使用的temp tablespace

SELECT se.username,sid,serial#,sql_address,machine,program,tablespace,segtype,contents

FROM v$session se ,

v$sort_usage su

WHERE se.saddr=su.session_addr

发现为PG1中有几个大的查询在跑 例如

其中一个sql-address的查询为

select * from v$sqltext

where address='C0000000C34DE9A8'

order by piece

是一个非常大的排序查询。可能是因此消耗了 过多的temp tablespace

ey in (select val from askey_cache) group by sv.ROUTE_CODE order

by sv.route_code

对于这种问题的最简单的解决办法就是 将这个排序查询kill掉

Alter system kill session sid ，serial#

如果只是短暂的存在 可以不做处理。
