Before starting installation check rapidwiz version:
Current Version of Rapid Install
The most current version of the Rapid Install wizard
is 12.0.0.22. You can obtain this version by applying
patch 5885627, available at OracleMetaLink. To verify
your current version, use the RapidWizVersion
executable, located in the rapidwiz directory on the
Start Here DVD.

$ cd /Stage12/startCD/Disk1/rapidwiz
$ ./RapidWizVersion

To update the Start Here DVD, uncompress the patch in
the main staging area to overwrite the startCD
directory.

$ cd /Stage12
$ unzip -o p5885627_R12_GENERIC.zip


OS user account settings:
Create groups and user:-

groupadd oinstall
groupadd dba
useradd -g oinstall -G dba oracle
useradd -g oinstall -G dba applmgr

Create directory structure & assign permissions:-

mkdir -p /d01/oracle
chmod -R 777 /d01

Change password of the users created:

passwd applmgr
passwd oracle

Check whether the both users have write permissions in the directory:-
touch abc (login using oracle user)

Start installation:-

$ /<installation file>/startCD/Disk1/rapidwiz/
$ ./rapidwiz
