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

--11g客户端导入

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

>log=/tmp/t_xifenfei.log tables=chf.t_xifenfei

--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.

One thought on “使用exp/imp 导入11g数据到9i”

  1. Export From 11g using EXP Utility Version 9iR2 Produces Corrupt Export Dump

    Applies to:
Oracle Server - Enterprise Edition - Version: 11.1.0.6 to 11.2.0.1 - Release: 11.1 to 11.2
Oracle Server - Enterprise Edition - Version: 9.2.0.1 to 9.2.0.8   [Release: 9.2 to 9.2]
Information in this document applies to any platform.
Symptoms
You need to export data from 11g and import into 9iR2. For this reason,
the exp utility version 9iR2 is used to extract data from 11g. There are two aspects of this problem:
1. On some Unix platforms, the exp utility either returns no errors or crashes with core dumps.
2. On Windows platforms, exp crashes with core dumps (Dr.Watson)
Both created dumps are corrupt, the imp utility crashes immediately after the export dump header is read.
Cause
Exp utility version 9iR2 internally uses the dictionary view EXU9DEFPSWITCHES to get information about some
parameters like PLSQL_COMPILER_FLAGS and NLS_LENGTH_SEMANTICS. The parameter PLSQL_COMPILER_FLAGS doesn't
exist in 11g anylonger and so the view EXU9DEFPSWITCHES returns unhandled 0 rows.
Solution
1. Connect to database 11g as SYSDBA with SQL*Plus
2. Change the definition of view EXU9DEFPSWITCHES from:
CREATE OR REPLACE VIEW exu9defpswitches (
                compflgs, nlslensem ) AS
        SELECT  a.value, b.value
        FROM    sys.v$parameter a, sys.v$parameter b
        WHERE   a.name = 'plsql_compiler_flags' AND
                b.name = 'nls_length_semantics'
to:
CREATE OR REPLACE VIEW exu9defpswitches (
                compflgs, nlslensem ) AS
        SELECT  a.value, b.value
        FROM    sys.v$parameter a, sys.v$parameter b
        WHERE   a.name = 'plsql_code_type' AND
                b.name = 'nls_length_semantics'
(see new parameter PLSQL_CODE_TYPE)
3. Re-start exp version 9iR2 to extract from 11g
4. Import the new dump using imp version 9iR2.
    回复

  2. 使用方法3:9i客户端导出,9i客户端导入 修改11g的view : exu9defpswitches ,如果我的表里面有blob字段，这个也可以吗。谢谢
