将Oracle 升级到9.2.0.8. 刚才查看无效对象，发现有几个ODCxx 开头的无效对象。 查看Oracle，说是9.2.0.8 以后的版本中，不知道的原因导致这些对象无效，这些对象在Oracle 10.2 以后的版本中已经删除掉了。 所以可以忽略这些无效对象。
SQL> select object_type,owner,object_name from all_objects where status='INVALID' and owner='SYS';
OBJECT_TYPE OWNER OBJECT_NAME
------------------ ------------------------------ ------------------------------
TYPE SYS ODCICOLINFO
TYPE SYS ODCIINDEXINFO
TYPE SYS ODCIINDEXINFO
TYPE SYS ODCIARGDESC
TYPE SYS ODCICOST
尝试修复对象：
SQL> ALTER TYPE SYS.ODCICOST COMPILE;
ALTER TYPE SYS.ODCICOST COMPILE
*
第 1 行出现错误:
ORA-02311: 无法使用 COMPILE 选项改变具有类型或表相关性的有效类型
ORA-02311: | cannot alter with COMPILE option a valid type with type or table dependents |
Cause: | An attempt was made to ALTER with COMPILE option a type that is valid and has type or table dependents. |
Action: | No need to perform this operation. |

Cause
It is unknown what has turned the objects invalid.
Solution
The objects in question will be dropped during upgrade to Oracle 10.2.x / 11.1.x / 11.2.x due to fact that the following script is run as part of upgrade: ?/rdbms/admin/c090200.sql:
...
Rem Drop these types so that they will be recreated (no longer evolved)
DROP TYPE ODCIIndexInfo FORCE;
DROP TYPE ODCICost FORCE;
DROP TYPE ODCIArgDesc FORCE;
DROP TYPE ODCIEnv FORCE;
