Oracle11g Oracle 11g:无法从EE转储还原XE中的方案

我使用了

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版本是否支持EE版本序列化方案的格式？

涉及多种类型的错误。但其中两个确实与enterprise edition中提供但express edition中未提供的功能相关：

ORA-00439: feature not enabled: Deferred Segment Creation

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

实际上，不可能直接导入这些转储。作为一种解决方法，您可以尝试在导入转储之前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支持的功能。一旦该表存在，导入将发出警告，指出该表已经存在，但如果架构兼容，则无论如何都应该导入数据

关于细粒度访问控制的错误最初可以忽略。但是为了生产性使用，您需要想出另一种控制数据访问的方法。

XE不支持11G EE的许多功能。最安全的方法是将版本as 10.2添加到impdp命令中。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 

impdp Target\u schema/@directory='DATA\u DUMP'dumpfile=DATA\u DUMP\u EE.dmp logfile=import.log REMAP\u schema=：version=10.2
