Oracle 10g中数据泵支持本地导出/导入分区表的分区,但是NET_LINK不支持分区表的分区。以下为导出部分实验,导入与导出相识。
本地导出:
C:\Users\xionglang>expdp test/test dumpfile=test.dmp logfile=test.log directory=dir_dump tables=t:p1
Export: Release 10.2.0.4.0 - 64bit Production on Tuesday, 19 June, 2012 22:57:09

NET_LINK方式导出:
C:\Users\xionglang>expdp test/test dumpfile=test1.dmp logfile=test.log directory=dir_dump tables=t:p2 network=test
ORA-39001: invalid argument value
ORA-39203: Partition selection is not supported over a network link.
很明显10g并不支持通过网络方式的分区选择功能。而且对于分区表而言,无论是导出还是导入,都是已一个整体完成的。
