在新上线的网管系统中，发现维护的数据库存在大量的无效对象，其中大量的无效对象（800多个）所有者为系统用户，虽然对应用暂时没有影响，但为了避免隐患，对无效对象进行了处理。

$select object_name,object_type,owner,created,last_ddl_time,timestamp from dba_objects where status='INVALID' order by 1,2;

无效对象产生可能有多种原因：

产生SQL对象名无效的问题大多原因是由于数据迁移导致的，另外应用程序的变化等也会造成数据库产生无效对象。

解决办法：

$ sqlplus /nolog

SQL*Plus: Release 10.2.0.1.0 - Production on Tue Mar 23 08:03:59 2010

SQL> conn /as sysdba
Connected.
SQL> @/oracle/10g/rdbms/admin/utlrp.sql

重新编译后，无效对象只有10多个，系统用户没有无效对象。
