ORA-12705: Cannot access NLS data files or invalid environment specified

安装oracle 出现的提示：

ORA-12705: Cannot access NLS data files or invalid environment specified

搜索了一下ORA-12705 这个关键字，大概意思就是字符集的配置问题

今天写脚本把oracle的数据同步到mysql,在oracle导出的时候，发现是乱码，然后加了export NLS_LANG=AMERICAN_AMERICA.UTF-8在脚本前，结构脚本连接

oracle数据库时报上面的ORA-12705错误。后来找到原因是和/etc/sysconfig/i18n中的设置不匹配。

拿我的机器作为例子：

[root@oracle01 /]# cat /etc/sysconfig/i18n
LANG="zh_CN.UTF-8"
[root@oracle01 /]#

那我的NSL_LANG的设置应该是这样的：

NLS_LANG='SIMPLIFIED CHINESE_CHINA.AL32UTF8'; export NLS_LANG

也就是说 NLS_LANG的设置/etc/sysconfig/i18n 文件中的设置对应。

类似“SIMPLIFIED CHINESE_CHINA.AL32UTF8” 带空格需要加单引号''，其他的无空格可以不加。

export NLS_LANG="AMERICAN_AMERICN.AL32UTF8"
export NLS_LANG="CHINESE_CHINA.ZHS16GBK"
