问题如下:


centos 8 最小版安装完oracle 18c或者19c以后,使用sqlplus登录或者退出回返回问号。


提示如下:



[oracle@localhost dbhome_1]$ sqlplus /nolog

SQL*Plus: Release 19.0.0.0.0 - Production on Fri Dec 11 09:16:06 2020

解决方案:



[#zeyu#]

修改Oracle用户的环境变量,执行命令:


vi ~/.bash_profile


文件末尾添加语句:export NLS_LANG=american_america.AL32UTF8,文件全文如下:


# .bash_profile

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

export ORACLE_HOME=/opt/oracle/product/19c/dbhome_1
export PATH=$PATH:$ORACLE_HOME/bin
export ORACLE_SID=ORCLCDB
export NLS_LANG=american_america.AL32UTF8
# User specific environment and startup programs

执行完毕后,执行命令:

source ~/.bash_profile

[/#zeyu#]



重新使用sqlplus登录即可正常。
