bash环境是配置没错的， 但就是报错：
复制代码 代码示例:
[root@jbxue ~]$ vi .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
unset USERNAME
export EDITOR=vi
export ORACLE_SID=dg1
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib
export PATH=/u01/app/oracle/product/10.2.0/db_1/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin
export PATH=$ORACLE_HOME/bin:$PATH
umask 022
解决方法：
复制代码 代码示例:
[root@jbxue ~]$ sqlplus /nolog
bash: sqlplus: command not found
[root@jbxue ~]$ ln -s $ORACLE_HOME/bin/sqlplus /usr/bin
ln: creating symbolic link `/usr/bin/sqlplus' to `/bin/sqlplus': Permission deni ed
[root@jbxue ~]$ su - root
Password:
[root@dg1 ~]# ln -s $ORACLE_HOME/bin/sqlplus /usr/bin
[root@dg1 ~]# su - oracle
[root@jbxue ~]$ sqlplus /nolog
