EXP-00011: XX.tab does not exist

测试环境:11.2.0.1.0  Linux x86 64-bit
现象:空表,记录为0的表导出会报错。
导出如下:
D:appproduct11.2.0dbhome_1BIN>exp labtt/labtt@192.168.101.127/orcl tables=(TE
ST_TIME,TEST_FR,my_test) FILE = D:TEST.DMP LOG=TEST.LOG

导入如下:

查看lwh下的表,没有MY_TEST。

总结:
看样子exp对延迟段创建的表,有一定影响。还是expdp靠谱,但是expdp又必须在服务器端执行。
如果要用exp,deferred_segment_creation又必须设置为false,这样新特性有没有利用。
所以要用exp导出,我都是先把表结构导出,然后再用exp,imp这么执行,这样就不怕空记录的表了。

我觉得应该在导出的时候oracle应该要把表定义导出。这样exp就完美了。
