2.5 环境变量配置

数据库配置后su 到oracle 用户下 发现无法登陆进数据库，

ps -ef|grep smon 看到实例已经在运行，提示没有配置环境变量

[root@ORACLE01T tmp]# su - oracle

[oracle@ORACLE01T ~]$ cd /opt/oracle/product/23ai/dbhomeFree/bin/

[oracle@ORACLE01T bin]$

[oracle@ORACLE01T bin]$ ./sqlplus / as sysdba

Error 6 initializing SQL*Plus

SP2-0667: Message file sp1<lang>.msb not found

SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory

[oracle@SZSPLORACLE01T ~]$ ps -ef|grep smon

oracle 42755 1 0 10:49 ? 00:00:00 db_smon_FREE

oracle 43387 43294 0 10:56 pts/0 00:00:00 grep --color=auto smon

-----------------------------------------------

配置环境变量

vi /home/oracle/.bash_profile

export PATH

export TMP=/tmp

export TMPDIR=$TMP

export ORACLE_SID=FREE

export ORACLE_BASE=/opt/oracle/

export ORACLE_HOME=$ORACLE_BASE/product/23ai/dbhomeFree

export TNS_ADMIN=$ORACLE_HOME/network/admin

export PATH=/usr/sbin:$PATH

export PATH=$ORACLE_HOME/bin:$PATH

# User specific environment and startup programs

配置好环境变量后，sqlplus登入提示idle instance，但是确认oracle_sid配置无误

PS:Oracle23ai新特性-报错信息更详细，提供报错信息的官网链接，但是个人认为作用不大，官网只是提供了报错的官方定义，对于解决问题并没有太大的作用

Solution：我这里的处理方法比较粗暴,直接kill掉smon 相当于强制关库，然后重新启动即可

这样Oracle 23ai rpm报的安装方式就完成了，相较于之前的版本安装确实简洁了非常非常多，关注博主，后续更新更多23ai新特性
