现在有个需求,需要使用exp/imp导入11g的数据库数据到9i中,解决这个问题一般来说想到三种方法思路,一个个尝试(其实从高版本服务端支持低版本客户端的原则,可以大概的猜测出使用9i的客户端处理该问题)

     方法1:导出导入都使用11g客户端

--11g客户端导出
[oracle@xifenfei ~]$ exp chf/xifenfei file=/tmp/t_xifenfei.dmp
>log=/tmp/t_xifenfei.log tables=chf.t_xifenfei

Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - Production

Export done in ZHS16GBK character set and AL16UTF16 NCHAR character set
server uses AL32UTF8 character set (possible charset conversion)

About to export specified tables via Conventional Path ...
. . exporting table                     T_XIFENFEI          2 rows exported
Export terminated successfully without warnings.

--11g客户端导入
[oracle@xifenfei ~]$ imp chf/xifenfei@ora9i file=/tmp/t_xifenfei_11g.dmp
>log=/tmp/t_xifenfei.log tables=chf.t_xifenfei

Import: Release 11.2.0.3.0 - Production on Fri May 18 18:17:24 2012

IMP-00058: ORACLE error 6550 encountered
ORA-06550: line 1, column 33:
PLS-00302: component \'SET_NO_OUTLINES\' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
IMP-00000: Import terminated unsuccessfully

    这个错误是版本不兼容导致:PLS-00302: component ‘SET_NO_OUTLINES’ must be declared

     方法2:11g客户端导出,9i客户端导入

--11g客户端导出
[oracle@xifenfei ~]$ exp chf/xifenfei file=/tmp/t_xifenfei.dmp
>log=/tmp/t_xifenfei.log tables=chf.t_xifenfei

--9i客户端导入

--至此导入成功,完成了11gr2数据导入到9ir2中

    通过一系列的实验证明,需要把11g的数据导入到9i中,需要使用9i的客户端进行,其中exu9defpswitches视图需要重建,否则会出现setSegmentation fault异常,导致导入失败.
