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:

Thu Nov 25 17:21:05 2004

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
