Exp and Imp are the best way to go for a single data move. Exp和Imp是进行单个数据移动的最佳方法。 I would second the suggestion of database links if you need to have continuous access to the data. 如果您需要连续访问数据，我会建议使用数据库链接。

One problem is the files produced by imp and exp are not backwardly compatible. 一个问题是imp和exp生成的文件不向后兼容。 That is if you use the 10g version of exp to create a dump file, you can't use the 9i version of imp to import the data. 也就是说，如果使用exp的10g版本创建转储文件，则不能使用imp的9i版本导入数据。

In this case you need to use the 9i version of exp, connected to the 10g database, then use the 9i version of imp to import the data. 在这种情况下，您需要使用连接到10g数据库的exp的9i版本，然后使用imp的9i版本导入数据。

You should be able to do the export using the usual exp / imp commands to perform the transfer. 您应该能够使用常用的exp / imp命令执行导出以执行传输。

You can also create a database link between the databases. 您还可以在数据库之间创建数据库链接。 exp / imp is faster but a database link makes it possible to do continuous export / import. exp / imp更快，但是数据库链接使连续导出/导入成为可能。
