Look on the site : metalink.oracle.com there is a note about it :
You receive this error because AIX 5.1 introduces the option to run the AIX
kernel in 64-bit mode. This mode is not supported, as Oracle 8i uses at
least one 32-bit kernel extension.
Oracle 8.1.7 Server Enterprise Edition 32-bit cannot be loaded on an
AIX 5L 64-bit server.
The solution for this is that AIX-based systems must be booted with kernels
in 32-bit mode.
For further details on this please refer to the article:
Note:109843.1
Hope that helps.

QUICK START GUIDE:
Oracle 8.1.x Installation Guide for AIX
PURPOSE
=======
This document is designed to be a quick reference that can be used when
installing Oracle 8.1.x on the AIX platform. It is NOT designed to take the
place of the Installation Guide. Please refer to the 'Oracle8i Installation
Guide Release x (8.1.x) for AIX-Based Systems' for additional information on
any
of the steps listed below.
OVERVIEW
========
Quick and easy steps for installing Oracle 8.1.x on AIX.
Each step should be done in the order that it is listed. These steps are
the
bare minimum that is necessary for a typical installation of the 8i RDBMS.
Verification of Version Certification:
======================================
Steps required to verify the version of Oracle is certified with the version
of the Operating System.
1. Enter http://metalink.oracle.com into a web brower
2. Click button labeled "Certify & Availability"
3. Click button labeled "Certification"
4. Click link "View Certifications by Product"
5. Select "Oracle Server" ... Click Submit
6. Select "Oracle Server - Enterprise Edition" ... Click Submit
7. Select "IBM RS/6000 AIX" or "IBM SP AIX" ... Click Submit
8. Select the version of Oracle ... Click Submit
9. Check the column "Status" for Certification Status
10. Click link "Yes" in the column "Addtl. Info." for PatchSet information.
Pre-requisite Requirements for System Administrator:
====================================================
For a successful installation of Oracle Rdbms software, make sure to
meet the requirements below. You can check them manually or use the
convenient "Unix InstallPrep script" to generate a report of configuration
steps that you need to perform prior the installation. Please refer to
[NOTE:189256.1] Unix InstallPrep script
For assistance with system administration issues please contact your system
administrator or operating system vendor.
NOTE: As of 25-Oct-2001, the only version of Oracle8i certified for use on
AIX 5.1 is 32-bit 8.1.7, which requires that the AIX 5.1 system is booted in
32-bit kernel mode. Booting the AIX 5.1 system in 64-bit kernel mode will
not
work with either 32-bit or 64-bit 8.1.7.
Steps required as the Root User (login as root to perform each of the
following
tasks):
1. Configure System Resources:
Ensure that the system has at least the following resources:
400 MB in /tmp *
256 MB of Physical Memory (RAM)
Three times the amount of Physical Memory for Swap space (unless
the
system exceeds 1 GB of Physical Memory, where two times the amount
of
Physical Memory for Swap space is sufficient)
* You may also redirect /tmp by setting the TEMP environment variable.
This is only recommended in rare circumstances where /tmp cannot be
expanded to meet free space requirements
2. Create a Software Owner and Group:
Create a Unix user and group that will own the Oracle software
(user = oracle, group = dba)
Use the "smit mkuser" command to add a new user.
Use the "smit mkgroup" command to add a new group.
This user must be local to the machine.
3. Create a Software Mount Point and DataFile Mount Points:
Create a mount point for the Oracle software installation
(at least 1.2 GB, typically /u01)
Create a second, third and fourth mount point for the database files,
control files, and log files to be created, (typically /u02, /u03, /u04).
The oracle user should own these mount points and all of the
directories below the mount point.
4. Test the Permissions:
Ensure the oracle user can write to the new mount points
As a test, change directories to each of the new mount point
directories as the oracle user and create a file or directory.
Example:
% touch /u01/test
5. Ensure that AIO is configured at system restart:
# lsdev -Cc aio
Verify that the status shown is "Available". If the status shown is
"Defined", then change the "STATE to be configured at system restart"
to "Available" after running the following command:
# smit chaio
6. Ensure that the math library is installed on your system:
# lslpp -l bos.adt.libm
If this fileset is not installed and "COMMITTED", then you must
install
it from the AIX operating system CD-ROM from IBM. With the correct
CD-ROM mounted, run the following command to start the process to
load
the bos.adt.libm fileset:
# smit install_latest
7. Mount CD-ROM:
Mount the Oracle 8.1.x CD-ROM using the command:
# mount -rv cdrfs /dev/cd0 /cdrom
8. Run the rootpre.sh script:
# cd /cdrom
# ./rootpre.sh
NOTE: You must shutdown ALL Oracle instances (if any) before running the
rootpre.sh script. Do not run the rootpre.sh script if you have a
newer version of an Oracle database already installed on this
system.
INSTALLATION STEPS
==================
Steps required to be performed as the Oracle user.
1. Set up the Environment Variables:
Set the following environment variables in the .profile or .login file of
the oracle user, (depending on the default shell for the oracle user),
before
starting the Installer.
The values in the examples are assuming that your software mount point is
/u01 and you are installing 8.1.7.
Parameter Value
---------- --------
ORACLE_HOME /u01/app/oracle/product/8.1.7
ORACLE_BASE /u01/app/oracle
PATH
/u01/app/oracle/product/8.1.7/bin:/usr/ccs/bin:
/usr/bin/X11:
and whatever else you want to have set
follows
these three items in the PATH
ORACLE_SID Set this to what you will call your database
instance.
(Typically 4 characters in length)
DISPLAY <ip-address>:0.0
If installing 8.1.5, you must set LINK_CNTRL:
LINK_CNTRL L_PTHREADS_D7
If installing 8.1.6 or higher, ensure that LINK_CNTRL is not set.
ENSURE THAT 'CLASS_PATH' AND 'EXTSHM' ARE NOT SET IN
THE ENVIORNMENT
2. Set the umask:
Set the oracle user's umask to 022 in your .login or .profile file.
3. Verify the Environment:
Log off and logon as the Oracle user to ensure all environment settings
are present.
Type env at the Unix prompt to view all the environment variables.
Before attempting to run the Oracle Universal Installer, verify that
you
can successfully run the following command:
% /usr/bin/X11/xclock
4. Start the Oracle Universal Installer and install the Oracle software:
Change directories to the CD-ROM and start the installer.
cd /cdrom
./runInstaller will start the Oracle Universal Installer
Verify that the Destination listed for File Location is your
ORACLE_HOME.
NOTE: If this is the first installation of Oracle 8i on this
machine, you will be prompted to run the script,
/tmp/orainstRoot.sh, before proceeding. This script
will
create the pointer file /etc/oraInst.loc which contains
the oraInventory directory location.
Select "Enterprise Edition" for the Install Category.
Select Typical to install the software, create a database and
start the database (Other selections are available for
minimal
or custom installs).
The install will begin.
Follow instructions regarding running root.sh and other
prompts.
When completed, the install will have created a default
database,
configured a Listener and started both for you.
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 unmount/eject
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 'umount' the 1st cd-rom.
