I have not installed 8i myself. but found this stuff on metalink. hpoe it helps. tell me if it works.


Note: If you are installing 8.1.7, depending on the products that are being
installed, the installer may prompt you to "insert Oracle8i disk 2
into your disk drive or supply an alternative location".

You may get "Device busy" messages when attempting to pfs_unmount
the 1st cdrom of the product set, because on the session that started
the installer the current working directory is the cdrom mount point.

To overcome this problem:

. Return to the session/window where the installer was launched.

. Press the Return key once or twice to get the Unix prompt.

. Change directory to a location other than the cdrom mount point,
for example 'cd /tmp'.

. You should now be able to 'pfs_umount' the 1st cd-rom.
