How to make Stage Area to install Oracle EBS R12

Oracle EBS Installation

1. login to the ROOT user and insert the start here DVD (wait till it is shown up)

2. goto the location
$ cd /mnt -- make your own mount point here
$ mkdir cdrom
$ df -h   -- to see the default mount point in the last line (suppose it is /media/r12Start)

$ umount /media/r12Start

$ mount /dev/cdrom /mnt/cdrom

3. From local user (i.e oracle)
$ cd /mnt/cdrom/Disk1/rapidwiz
$ perl adautostage.pl
    give the stage directory path
    enter n for auto mount
    entter default value for mount point
    enter default value for umount

After start here dvd is completed

$ umount /mnt/cdrom
$ eject   -- to eject the cd
$ df -h   -- to confirm

4. un mount the cd rom from its default mount point

$ df -h to see the default mount point in the last line
$ umount /media/orardb

$ df -h -- to confirm it is un mounted

6.Insert next DVD, now mount to your own mount point

$ mount /dev/cdrom /mnt/cdrom
(continue with this loop from 4 to 6 from root user)
