ORACLE 11g导入9i dump的问题及解决

因为系统迁移,需要将一部分的9i的数据导入11g的库里, 目标库是11.2.0.3.0 64位的环境。 导入dump的时候,有一个比较大的分区表,需要用导入分区的方式,就写了如下的命令。但是奇怪的是过了一会,抛出来一个imp的错误就完事了。

-bash-4.1$ imp n1/n1@testdb tables=TEST_DB:TEST_DB_PAR_P1        file=TEST_DBP1.dmp     ignore=Y statistics=none grants=n indexes=n buffer=9102000 log=imp_log_TEST_DB_PAR_P1_test

我以为我的表名和分区写的有问题,检查了一下,都在的。 为了继续,然后尝试直接按表导入,但是还是导不进去,不过报错信息倒是不太一样了。

-bash-4.1$ imp n1/n1@testdb tables=TEST_DB       file=TEST_DBP1.dmp     ignore=Y statistics=none grants=n indexes=n buffer=9102000 log=imp_log_TEST_DB_PAR_P1_test

开始怀疑是不是dump有问题了,确认了下checksum也是一样的。 最后尝试如下的方式,加了 fromuser ,touser选项,竟然可以了。

imp n1/n1@testdb tables=TEST_DB:TEST_DB_PAR_P1      fromuser=TEST_APPO touser=PSCNVDBO1   file=TEST_DBP1.dmp     ignore=Y statistics=none grants=n indexes=n buffer=9102000 log=imp_log_TEST_DB_PAR_P1           &

查看metalink,也没有发现类似的帖子。也算自己为ORACLE出了一点力吧。
