四、安装oracle
软件
[oracle@rac1 ~]$ cd /home/software/database
[oracle@rac1 database]$ ls
doc install response rpm runInstaller sshsetup stage welcome.html
[oracle@rac1 database]$ ./runInstaller
接下来又是漫长的等待，但这一步是安装过程中唯一不会出问题的。
节点1
[root@TRAC1 lib]# /home/app/oracle/product/11.2.0/root.sh

The following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME= /home/app/oracle/product/11.2.0
