subdirectories in the mount point directory that you identified and set the

# mkdir -p /mount_point/app/
# chown -R oracle:oinstall /mount_point/app/
# chmod -R 775 /mount_point/app/
For example:

8 Configuring the oracle User’s Environment
You run Oracle Universal Installer from the oracle account. However, before you start
Oracle Universal Installer, you must configure the environment of the
oracle user. To
configure the environment, you must:
■ Set the default file mode creation mask ( umask ) to 022 in the shell startup file.
■ Set the DISPLAY environment variable.
To set the
oracle user’s environment:
1. Start a new terminal session, for example, an X terminal ( xterm ).
2. Enter the following command to ensure that X Window applications can display
on this system:
$ xhost fully_qualified_remote_host_name
For example:
$ xhost somehost.us.example.com
3. If you are not logged in to the system where you want to install the software, then
log in to that system as the
oracle user.
4. If you are not logged in as the oracle user, then switch user to oracle :
$ su - oracle
5. To determine the default shell for the oracle user, enter the following command:
$ echo $SHELL
6. To run the shell startup script, enter one of the following commands:
■ Bash shell:
$ . ./.bash_profile
■ Bourne or Korn shell:
$ . ./.profile
■ C shell:
% source ./.login
