今天配置了一下11gR2下单实例asm，发现基于css之上的一切resource或者service都通过crs_*系列命令管理起来了，就像在rac中管理一样，挺爽的。

下面是安装grid之后运行root.sh的提示内容，放在这里做个记录

[root@localhost grid]# ./root.sh
Running Oracle 11g root.sh script...

The following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME= /opt/grid/11.2.0/grid

Enter the full pathname of the local bin directory: [/usr/local/bin]:
The file "dbhome" already exists in /usr/local/bin. Overwrite it? (y/n)
[n]:
The file "oraenv" already exists in /usr/local/bin. Overwrite it? (y/n)
[n]:
The file "coraenv" already exists in /usr/local/bin. Overwrite it? (y/n)
[n]:

Entries will be added to the /etc/oratab file as needed by
Database Configuration Assistant when a database is created
