现在有个需求，需要使用 exp/imp 导入 Oracle 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

. . 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

IMP-00058: ORACLE error 6550 encountered

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

– 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。
