ORACLE 11G数据库迁移到9I报 IMP-00003 ORA-00096 IMP-00000

haloi

今天有个朋友问我为什么11G的exp出来的文件不能导入到9I中？由于exp/imp工具的不兼容性，把高版本的数据库导到低版本时，需要使用低版本的exp/imp工具来导入导出。朋友用9i的exp去导出11G数据后再imp导入到9i中，正常导入，然而我自己在自己测试环境测试中切报错了，报错信息如下：

在11G，SHOW PARAMETER命令已经找不到plsql_compiler_flags这个参数，由另一个参数代替。

GOOGLE,BAIDU,METALINK相关的错误代码后没有找到解决方法。更改关键字plsql_compiler_flags在metalink找到解决方法,如下：
