oracle中文亂碼的解決方法（linux）

亂碼：

[oracle@orcl12c ~]$ sqlplus / as sysdba

SQL*Plus: Release 12.2.0.1.0 Production on Fri Dec 6 10:45:56 2019

Copyright (c) 1982, 2016, Oracle.  All rights reserved.


???:
Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production

SQL> startup
ORA-01081: ????????? ORACLE - ??????
SQL> exit

解決辦法：
修改oracle用戶的環境變量文件。加入NLS_LANG="SIMPLIFIED CHINESE_CHINA.al32utf8"; export NLS_LANG

實例在startup狀態下，查詢

SQL> select userenv('language') from dual;

USERENV('LANGUAGE')
----------------------------------------------------
SIMPLIFIED CHINESE_CHINA.AL32UTF8

配置用戶環境變量：

[oracle@orcl12c ~]$ cat ~/.bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

export ORACLE_SID=orcl
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.2.0/dbhome_1
export PATH=$PATH:$ORACLE_HOME/bin
export DISPLAY=:0
export UMASK=022
NLS_LANG="SIMPLIFIED CHINESE_CHINA.al32utf8"; export NLS_LANG
PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH

如圖：

ok，命令行中文顯示正常了。
