今天登录一台服务器用roote用户登录的,在切换到oracle用户,执行sqlplus sys/ as sysdba进入数据库提示如下错误:
SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory
在/home/oracle目录下查看文件.bash_profile,它是隐藏文件。
$ cat .bash_profile # .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs PATH=$PATH:$HOME/bin export PATH export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=/u01/app/oracle/product/11.1.0/db_1 export ORACLE_SID=orcl export PATH=$ORACLE_HOME/bin:$PATH export LD_LIBRARY_PATH=$ORACLE_HOME/lib LANG=zh_CN.UTF-8; export LANG NLS_LANG='SIMPLIFIED CHINESE_CHINA.AL32UTF8'; export NLS_LANG
[oracle@localhost ~]$ cd $ORACLE_HOME
-bash: cd: /u01/app/oracle/product/11.1.0/db_1: 没有那个文件或目录
发现oracle安装定义的家目录是在/u01/app/oracle/product/11.1.0/db_1目录下的 u01目录是root用户的权限,在切回到root用户,执行如下命令: [root@localhost ~]# cd $ORACLE_HOME [root@localhost dbhome_1]# pwd /u01/app/oracle/product/11.2.0/dbhome_1 [root@localhost dbhome_1]# sqlplus / as sysdba 或是 [root@localhost dbhome_1]# cd bin [root@localhost dbhome_1]# pwd /u01/app/oracle/product/11.2.0/dbhome_1/bin [root@localhost bin]# ./sqlplus / as sysdba SQL*Plus: Release 11.2.0.4.0 Production on Thu Oct 12 17:20:48 2017 Copyright (c) 1982, 2013, Oracle.
