oracle NLS_LANG环境变量设置

查询以下三个参数值：
NLS_LANGUAGE SIMPLIFIED CHINESE
NLS_TERRITORY CHINA
NLS_CHARACTERSET AL32UTF8

查询NLS_LANG的组成规则为NLS_LANGUAGE_NLS_TERRITORY.NLS_CHARACTERSET

export NLS_LANG='SIMPLIFIED CHINESE_CHINA.AL32UTF8'

重新登录sqlplus，显示正常，不乱码。

[oracle@localhost ~]$ export NLS_LANG='SIMPLIFIED CHINESE_CHINA.AL32UTF8'
[oracle@localhost ~]$ sqlplus / as sysdba
