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 Export: Release 11.2.0.3.0 - Production on Fri May 18 18:15:18 2012 Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved. Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - Production With the Partitioning, OLAP, Data Mining and Real Application Testing options 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 Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved. 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 Export: Release 11.2.0.3.0 - Production on Fri May 18 18:15:18 2012 Copyright (c) 1982, 2011, Oracle and/or its affiliates.

方法3:9i客户端导出,9i客户端导入

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.
