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：

1. Confirm XML DB is not already installed.
   • SELECT username FROM DBA_USERS where username = 'XDB'; returns 0 rows.
   • DESCRIBE RESOURCE_VIEW fails.
2. As SYS,perform the XML DB installation - Note: this will not be a complete build due to Oracle Bug 9818995:
   • @?/rdbms/admin/catqm.sql xdb <xml db tablespace> <xdb temp tablespace> <use secure files yes|no>
3. As SYS,grant the relevent permissions to the XDB user:
   • GRANT EXECUTE ON utl_file TO xdb;
   • GRANT EXECUTE ON dbms_lob TO xdb;
4. As SYS,ensure their are no invalid objects:
   • @?/rdbms/admin/utlrp.sql
5. 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.
6. As SYS,install the missing contents caused by Oracle Bug 9818995:
   • SHUTDOWN IMMEDIATE;
   • STARTUP UPGRADE
   • @?/rdbms/admin/xsdbmig.sql
   • SHUTDOWN IMMEDIATE;
   • STARTUP
7. As SYS,ensure their are no invalid objects:
   • @?/rdbms/admin/utlrp.sql
8. 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="
