Oracle ORA-31000: Resource 'http://xmlns.oracle.com/xdb/acl.xsd' is not an XDB schema 解决方法
数据库是从Oracle10.2.0.5 升级到11.2.0.3的：
Oracle 使用RMAN 将 DB 从10g 直接Restore 到11g 示例
http://blog.csdn.net/tianlesoftware/article/details/7311352
在升级的过程中就有这个问题，同时还伴随这XDB和ORDIM 两个组件无效的问题，如下：
SQL> col comp_id for a15
SQL> col version for a15
SQL> col comp_name for a30
SQL> selectcomp_id,comp_name,version,status from dba_registry;

在用XDB Reload 的方法，重建了所有XDB对象后，XDB变成有效对象：
SQL> selectcomp_id,comp_name,version,status from dba_registry;
COMP_ID COMP_NAME VERSION STATUS
--------------------------------------------- --------------- -----------------

APS OLAP Analytic Workspace 11.2.0.3.0 VALID
17 rows selected.
这里的ORDIM 组件还是无效的，在Reload 该组件时，执行@?/ord/im/admin/imxreg.sql;脚本的时候，还是有大量的这种错误：
SQL> @?/ord/im/admin/imxreg.sql;
PL/SQL procedure successfully completed.

ORDIM 的Reload 也会挂住，所以在XDB和ORDIM 组件都无效的情况，不能采用Reload XDB组件的方法来解决，而应该采用reinstall XDB的方式来解决，这样就可以避免出现ORA-31000的错误，也可以顺利Reload ORDIM 组件。
关于XDB 组件重建和Reload 的更多内容，参考我的Blog：

--卸载XDB：
SQL> @?/rdbms/admin/catnoqm.sql
--安装XDB
SQL>shutdown immediate
SQL>startup
SQL> @?/rdbms/admin/catqm.sql oracle SYSAUX TEMP YES
SQL> @?/rdbms/admin/utlrp.sql
验证： XDB 已经正常了：
SQL> set wrap off
SQL> col comp_id for a15
SQL> col version for a15
SQL> col comp_name for a30
SQL> selectcomp_id,comp_name,version,status from dba_registry;

在次Reload ORDIM组件：
SQL>alter session set current_schema="ORDSYS";
SQL> @?/ord/im/admin/imxreg.sql;
SQL>@?/ord/im/admin/impbs.sql;
SQL> @?/ord/im/admin/impvs.sql;
SQL> @?/ord/im/admin/imtyb.sql;
SQL> @?/ord/im/admin/implb.sql;
SQL> @?/ord/im/admin/imxrepos.sql;
这次一次通过，没有遇到ORA-31000错误。
SQL> selectcomp_id,comp_name,version,status from dba_registry;

小结：
（1） 对于XDB 和 ORDIM 组件同时失效的情况下，只能采用reinstall XDB组件，而不能采用Reload XDB组件的方法。 否则在Reload ORDIM 组件的过程中就会遇到ORA-31000的错误：
ORA-31000:Resource 'http://xmlns.oracle.com/xdb/acl.xsd' is not an XDB schema document
（2） 不同的Oracle 版本reinstall 和Reload 方法有出入，具体参考：
