ERR_1000001:未知的系统错误(ORA-01652: unable to extend temp segment by 128 in tablespace TEMP
ORA-06512: at "WMSYS.WM_CONCAT_IMPL", line 31
) Nested Exception is:ORA-01652: unable to extend temp segment by 128 in tablespace TEMP
ORA-06512: at "WMSYS.WM_CONCAT_IMPL", line 31
可以用如下语句进行temp 表空间的使用情况：
select * from
(select username,session_addr,sql_id,contents,segtype,blocks*8/1024/1024 gb
from gv$sort_usage order by blocks desc)
where rownum<=200;
经检查发现是一个查询语句把temp表空间给撑满了。
