在11g安装 XML DB 组件

昨晚做全库impdp导入时，发现有些表使用了xml的存放。导致导入的时候表都无法创建。

因dbca建库的只安装了jvm组件，所以需要安装XML DB组件。

安装步骤如下：
Confirm XML DB is not already installed.
SELECT username FROM DBA_USERS where username = 'XDB'; returns 0 rows.
DESCRIBE RESOURCE_VIEW fails.

As SYS, perform the XML DB installation - Note: this will not be a complete build due to Oracle Bug9818995:
@?/rdbms/admin/catqm.sql xdb <xml db tablespace> <xdb temp tablespace> <use secure files yes|no>

As SYS, grant the relevent permissions to the XDB user:
GRANT EXECUTE ON utl_file TO xdb;
GRANT EXECUTE ON dbms_lob TO xdb;

As SYS, ensure their are no invalid objects:
@?/rdbms/admin/utlrp.sql

Assuming an spfile is in use, as SYS configure the XDB dispatcher:
ALTER SYSTEM SET DISPATCHERS="(PROTOCOL=TCP)(SERVICE=<SID>XDB)" SCOPE=both;
If init.ora is in use, edit the init.ora file instead.

As SYS, install the missing contents caused by Oracle Bug 9818995:
SHUTDOWN IMMEDIATE;
STARTUP UPGRADE
@?/rdbms/admin/xsdbmig.sql
SHUTDOWN IMMEDIATE;
STARTUP

As SYS, ensure their are no invalid objects:
@?/rdbms/admin/utlrp.sql

As SYS, confirm the XML DB is now fully installed by running the following query and returning the following output:

SELECT
object_value
FROM
xdb.xs$securityclass
WHERE
EXTRACTVALUE(object_value, '/securityClass/@targetNamespace')='http://xmlns.oracle.com/plsql'
AND
EXTRACTVALUE(object_value, '/securityClass/@name')='network'
/

OBJECT_VALUE
--------------------------------------------------------------------------------
<securityClass xmlns="http://xmlns.oracle.com/xs" xmlns:dav="DAV:" xmlns:plsql="
