oracle用户的ORACLE_SID按照规划的实例名进行相应设置，例如规划实例名为xdja，这里的ORACLE_SID分别设置为xdja1/xdja2

首先配置本地yum源，软后使用yum命令安装所有依赖包

查看是否认出前面配置的共享磁盘
# ll /dev/sd*

查出每块共享磁盘的wwid
# scsi_id --whitelisted --replace-whitespace --device=/dev/sdb

# scsi_id --whitelisted --replace-whitespace --device=/dev/sdc

36000c295385cc5aec648a12c665d88e0

根据wwid对共享磁盘进行绑定
