Oracle RMAN出現 rman: can't open target

$ rman target /
rman: can't open target

這是因為呼叫了非ORACLE的RMAN
$ which rman
/usr/X11R6/bin/rman

解決方法-修改環境變數
修改.bash_profile
把oracle的放到最前面，修改成
export PATH=$ORACLE_HOME/bin:${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
登出後再登入，就會用到oracle的RMAN
$ which rman
~/product/10.2.0/db/bin/rman
