Why Do I Need to be Able to Log In as Root at Certain Times During Installation?

Oracle Application Server Installation Guide

At least once during installation, the installer prompts you to log in as the root user 
and run a script. You need to be root because the script edits files in the 
/var/opt/oracle

 directory.

The installer prompts you to run the root.sh script in a separate window. This script 
creates files in the local bin directory (/usr/local/bin, by default).

If the script finds files of the same name, it prompts you if you want to override the 
existing files. You should back up these files (you can do this from another window), 
then overwrite them.

The following lines show the prompts from the root.sh script. The default values are 
enclosed in square brackets.

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]:  y

 Copying dbhome to /usr/local/bin ...

The file "oraenv" already exists in /usr/local/bin.  Overwrite it? (y/n)[n]:  y

 Copying oraenv to /usr/local/bin ...

The file "coraenv" already exists in /usr/local/bin.  Overwrite it? (y/n)[n]: y

 Copying coraenv to /usr/local/bin ...

After you run root.sh, you may see warnings that begin with "chmod: WARNING: 
Corresponding set-ID also disabled..." You may ignore these warnings.

During the installation of an Oracle Application Server instance, you should not 
change the configuration or passwords of other installations in your environment. For 
example, if there is an OracleAS Infrastructure installation in your environment, you 
should not modify it during the installation of a middle tier.

Inventory directory

When you install the first Oracle product on a computer, you 
specify this directory, which the installer uses to keep track of 
which Oracle products are installed on the computer. In 
subsequent installations, the installer uses the same inventory 
directory.

/var/opt/oracle

 

directory

This directory contains information on locations of Oracle homes 
on the computer.

If you installed Oracle9iAS Release 2 (9.0.2) on your computer, 
this directory also contains files that provide information for 
Oracle Enterprise Manager 10g.

/tmp

 directory

The installer writes files needed only during installation to a 
"temporary" directory. By default, the "temporary" directory is 
/tmp

. To specify a different directory, set the TMP environment 

variable. See 

 for details.
