基于OFA，如果是单实例的文件系统，则遵从如下目录

/u01   初始化50G 存放 oracle RDBMS software
/u02   vgoradata_lvoradata01  用于存放系统数据文件 及 用户的数据表空间
/u03   vgoraindx_lvoraindx01  用户的索引表空间
/u04   vgoraarch_lvoraarch01  归档日志目录，可存放归档，闪回，RMAN等文件

oracle,grid 用户的设置文件

vi /etc/profile

if [ $USER = "oracle" ] || [ $USER = "grid" ]; then
        if [ $SHELL = "/bin/ksh" ]; then
              ulimit -p 16384
              ulimit -n 65536
        else
              ulimit -u 16384 -n 65536
        fi
        umask 022
fi
