我使用expdp/impdp实用程序。

在 Oracle 11g XE 中，并非所有表都被还原。以下是日志的一些摘录：

XE版是否支持EE版序列化方案的格式？

涉及多种类型的错误。但是其中两个确实与企业版中可用但在快捷版中不可用的功能有关：

ORA-00439: feature not enabled: Deferred Segment Creation

ORA-00439: feature not enabled: Fine-grained access control

确实不可能直接导入这些转储。作为一种解决方法，您可以在导入转储之前尝试自己创建有问题的表。使用源系统中的定义并删除或替换不受支持的功能。表存在后，导入将发出表已存在的警告，但如果架构兼容，它仍应导入数据。

关于细粒度访问控制的错误最初可以忽略。但对于生产性用途，您需要想出另一种方法来控制对数据的访问。

XE 不支持 11G EE 的许多功能。最安全的方法是将版本作为 10.2 添加到您的 impdp 命令。下面给出的例子

impdp Target_schema/<password>@<DB_TNSNAME>  directory='DATA_DUMP' dumpfile=data_dump_EE.dmp logfile=import.log REMAP_SCHEMA=<Source_Schema>:<Target_schema> version=10.2
