刚刚接触oracle不久，最近做window 32位系统下数据库（oracle10g）到 linux 64位系统（oracle11g）的表空间迁移，遇到如下问题：
将数据从原库中通过rman工具命令transport tablespace导出后，上传至linux系统中，执行impdp导入出现如下问题：
$ impdp system/xxxxx@xxx directory=dumpdir dumpfile='DMPFILE.DMP' transport_datafiles=/oracle/ora11g/oradata/elms/PERFSTAT01.DBF,/oracle/ora11g/oradata/elms/USERS001.DBF,/oracle/ora11g/oradata/elms/TBS_ELMS_8610_DEV_PRD01.DBF logfile=imp_8610_three.log

请高手们帮忙看看，是怎么回事啊，我在window下执行导入时，可正常导入，但是编译(utlirp.sql)是又有报错：select to_number（'must_be_open_upgrade'）from v$instance where status ！='open migrate'--------ora-01722:无效的数字。
