linux下 sqlplus命令无效，怎么解决
提示：
[oracle@localhost /]$ sqlplus
bash: sqlplus: command not found
我的provile设置：
.bah_profile:
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$HOME/bin:$ORACLE_HOME/bin:$PATH
export PATH
ORACLE_HOME=/u01/app/oracle/db_1; export ORACLE_HOME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_SID=demo1; export ORACLE_SID
[解决办法]
PATH=语句放在ORACLE_HOME=的后面，再export
