Error 6 initializing SQL*Plus

SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory
搞了好久，最后还是环境变量问题！！！
一开始的环境变量这么写的：
HOME=/opt/aa
ORACLE_HOME=/opt/aa/oracle/10.2.0/db_1
PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
最后改成了
export HOME=/opt/aa
export ORACLE_HOME=$HOME/oracle/10.2.0/db_1
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
关键点，只是把前面都增加了export，其他都是次要的！！！原来还是因为环境变量啊
