108.You are installing Oracle Database 11g on your server. During the installation Oracle Universal

Installer (OUI) prompts you to enter the path of the inventory directory and also prompts you to specify an

operating system group name. Which statement is true in this case?

A.The ORACLE_BASE parameter is not set.

B.The installation is being performed by the root user.

C.The operating system group that will be specified should have root user as its member.

D.The installation is being performed without the "Create Starter Database" option selected.

E.The operating system group that will be specified must have permission to write to the inventory directory.

答案：E

解析：

这里其实是在安装过程中，指定inventory目录的路径，并且指定操作系统用户组名

inventory这个目录，其实就是安装软件的时候存储一些安装的信息，它的主要作用就是安装和升级，它的路径是通过oraInst.loc文件指定的
指定的系统组对该目录必须有些的权限，因为安装的时候会往里面写，还有日志

A：ORACLE_BASE解释如下

ORACLE_BASE is the root of the Oracle Database directory tree. The Oracle Base directory is the top level directory that you can use to install the various oracle software products. 

You can use the same Oracle base directory for multiple installations. 

For example, /u01/app/oracle is an Oracle base directory created by the oracle user.
