在oracle11g的active dataguard中，在备库运行一段时间，一般为几天，然后查询数据视图，数据库就hang很长时间，然后抛出错误：

ORA-00604: error occurred at recursive SQL level 1  
ORA-01555: snapshot too old: rollback segment number 21 with name  
"\_SYSSMU21\_3288119158$" too small

oracle版本：

到oracle的metlink中查，发现是11.2.0.2.0 的bug : 10018789,下载p10018789\_112020\_Linux-x86-64.zip（424K）补丁修复。
