这一步也可以放到安装完oracle软件后再做。

任一节点，grid用户下执行：

[grid@rac1 ~]$ asmcmd

ASMCMD> mkdg '<dg name="SASDATA" redundancy="external"> <dsk string="/dev/asmdisk_sasdata1" /> <dsk string="/dev/asmdisk_sasdata2" /> <dsk string="/dev/asmdisk_sasdata3" /> </dg>'

[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
