1.使用sys登录Oracle，利用dbms_xdb修改端口设置

  SQL> -- Change the HTTP/WEBDAV port from 8080 to 8081
  SQL> call dbms_xdb.cfg_update(updateXML(
    2        dbms_xdb.cfg_get()
    3      , '/xdbconfig/sysconfig/protocolconfig/httpconfig/http-port/text()'
    4      , 8081))
    5  /

  Call completed.

  SQL> -- Change the FTP port from 2100 to 2111
  SQL> call dbms_xdb.cfg_update(updateXML(
    2         dbms_xdb.cfg_get()
    3       , '/xdbconfig/sysconfig/protocolconfig/ftpconfig/ftp-port/text()'
    4       , 2111))
    5  /

  Call completed.

  SQL> COMMIT;

  Commit complete.

  SQL> EXEC dbms_xdb.cfg_refresh;

  PL/SQL procedure successfully completed.

2.使用OEM console，选择数据库，XML Database，Configuration。更改XDB的有关设置。
