今天是周末，难得可以休息一下，晚上8点来到办公室查看下库的情况，发现有条日志报错，这条语句很熟悉了，也就是这几天一直和开发那边沟通的一条报表的存储过程，该语句近一段时间以来一直雄踞ADDM 性能分析中占Top SQL Statements第一位，在7月18号时该语句把undo表空间占满了，日志中出现ORA-01555 caused by SQL statement below 提示，所以马上查看UNDO表空间，

20:25:00 sys@PORTALDB> select sum(maxbytes)/1024/1024/1024,SUM(USER_BYTES)/1024/1024/1024 FROM dba_data_files where tablespace_NAME=‘UNDOTBS1‘;

SUM(MAXBYTES)/1024/1024/1024 SUM(USER_BYTES)/1024/1024/1024
---------------------------- ------------------------------
                  63.9999695                     63.9989624

Elapsed: 00:00:00.02
20:25:02 sys@PORTALDB> select sum(maxbytes)/1024/1024/1024,SUM(USER_BYTES)/1024/1024/1024 FROM dba_data_files where tablespace_NAME=‘UNDOTBS2‘;

SUM(MAXBYTES)/1024/1024/1024 SUM(USER_BYTES)/1024/1024/1024
---------------------------- ------------------------------
                  63.9999695                     63.9989624

undo_management                      string      AUTO
undo_retention                       integer     900
undo_tablespace                      string      UNDOTBS1

这次表空间几乎没有怎么使用；实际上看表空间的大小我会通过OEM查看比较简单明了；

20:29:02 sys@PORTALDB> SELECT DISTINCT STATUS  ,COUNT(*)  , SUM(BYTES) / 1024 / 1024 / 1024   FROM DBA_UNDO_EXTENTS GROUP BY STATUS;
