Install Problem (really libaio architecture issue)

During the "Configuration Assistants" startup I have an error. The "Oracle Net Configuration Assistant" succeeded but then the "Oracle Database Configuration Assistant" failed. It "popped-up" a window saying "ORA-12547: TNS:lost contact". There is only an "OK" button as shown here:

I click it and get a new pop-up window saying:

OUI-25031:  Some of the configuration assistants failed.  It is strongly
recommended that you retry the configuration assistants at this time.
Net successfully running any "Recommended" assistants means your
system will not be correctly configured.
1. Check the Details panel on the Configuration Assistant Screen to
see the errors resulting in the failures.
2. Fix the errors causing thses failures.
3. Select the failed assistants and click the 'Retry' button to retry
them.

This is what the screen looks like then:

I tried stopping the firewall with service iptables stop and retrying but the same thing happens.

The Details box contains:

Solution

After much looking around I found that this problem is because I had installed only the x86 (32bit) version of libaio. You can see the problem via:

[oracle@umors cfgtoollogs]$ sqlplus "SYS/######## as SYSDBA"      

'########' should really be the correct password

SQL*Plus: Release 10.2.0.1.0 - Production on Thu Jul 13 14:55:47 2006

oracle+ASM: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
ERROR:
ORA-12547: TNS:lost contact


Enter user-name: 

The solution is to use up2date --arch=x86_64 libaio

Retrying the above commands then works (puts you at an sqlplus prompt).
