RAC安装时需要执行4个脚本
1) $Oracle_BASE/oraInventory/orainstRoot.sh (clusterware 结束时执行)
2) $CRS_HOME/root.sh (clusterware 结束时执行)
3) $CRS_HOME/bin/vipca.sh(该脚本是在第二个节点执行$CRS_HOME/root.sh时被自动调用)
4) $ORACLE_HOME/root.sh (安装完数据库以后执行)

if [ $? != 0 ]; then

echo "The execution of the script is complete"
从脚本我们可以看出，这个脚本主要是创建/var/opt/oracle目录（如果不存在的话）,再在该目录下建oraInst.loc文件（该文件记录orainventory的位置和组）。并改变orainventory的属性。

从输出我们可以看出，该脚本主要执行crs的配置，格式化ocr disk,更新/etc/inittab文件，启动css进程，在/var/opt/oracle/新建了ocr.loc文件及，scls_scr，oprocd文件夹。
