ORA-00904: "DROP_SEGMENTS": invalid identifier 解决方法

之前按用户imp了一个9i的数据库，今天发现Job 执行失败，alert log 显示：
ORA-00904: "DROP_SEGMENTS": invalid identifier



上网搜了一下， 摘抄如下， 说是要执行下catpatch.sql 脚本。



Oracle 9.2.0.5 added the DROP_SEGMENTS column to the DBA_TAB_MODIFICATIONS view. Internally, the dollar table sys.mon_mods$ received the new drop_segments column. Guess who's responsible for adding this new column during the patch process?
Yup, it's catpatch.sql. Oh, joy!

If you don't run catpatch when patching to 9.2.0.5, a few things will happen with regards to the drop_segments column:
SMON will complain profusely in alert.log whenever it tries to update sys.mon_mods$. That means you get this error message every 15 minutes, or sooner:

Errors in file /u01/app/oracle/admin/mydb/bdump/mydb_smon_8201.trc:
ORA-00904: "DROP_SEGMENTS": invalid identifier


DBMS_STATS.FLUSH_DATABASE_MONITORING_INFO will fail.
According to Metalink Note 285315.1, you'll also get the ORA-00904 error in the alert.log on DROP TABLE and TRUNCATE TABLE.
You will get the ORA-00904 error when you try to update statistics with "GATHER STALE".
If you can't update statistics, you will have bad optimizer plans.



解决方法如下：
1. shutdown database
2. startup migrate
3. @?/rdbms/admin/catpatch.sql --升级数据字典
4. @?/rdbms/admin/catalog.sql --创建系统常用的数据字典视图和同义词
5. @?/rdbms/admin/utlrp.sql --编译存储过程
6. 重启数据库
