如何从异构环境下9i到10G的迁移？

stzlz

目前要完成一项任务，从windows环境下的9i把数据迁移到AIX下的10GR2。
数据已经从9i上exp出来了，用SYS用户加full=y参数。
在imp到10G时报了很多错。
10G的环境需要怎么准备呢？谢谢

怎么操作的？报了什么错误呢？

你可以imp system/passwd fromuser=用户名（业务系统所属） touser=用户名（AIX下新建的业务系统所属）file=文件名  来导入

stzlz

我有一点搞不清楚，因为之前数据库是厂家布置的，不清楚有几个用户需要导出。所以我用的是FULL导出。
另外问一点，在导入数据之前要不要先建好表空间？还是在导入数据时会自动建表空间？

yzkarchive

先用rows=n导入一次数据库结构，再导入一次数据试下

import的时候, 系统用户的数据不要导入

试过楼上二位的作法，依然不行，提示：

很明显，你应该建上原来系统的表空间。但是角色和用户为什么创建上，就比较奇怪了。

是否需要将相关的用户等信息建立好啊。
