Hi Istvan,

I have (32bit) running successfully in a Centos 5.3 vm. This doesn't
entirely match your situation I realize but might help others. I did have
some *fun* installing. Things I learned.  Others will already know this.

1) LD_ASSUME_KERNEL controls which libraries are loaded as per In particular

2.4.20 and above is new thread model
2.4.19 is Linux Threads
2.4.1 is old threads
Linux Threads is not available in modern kernels at all (like Centos 5.3) so
LD_ASSUME_KERNEL breaks things quite badly there (or rather allows the
broken app to show how broken it is).

2) The install instructions for RHEL4 don't necessarily work for  distros
compatible with a higher release.

3) when the installer breaks you can tail the log file (in
$ORACLE_HOME/install) and find what the linking stage was doing when it
broke. This can be very useful.

4) I needed a number of compatibility rpms, in particular

I didn't however need to move g++ and gcc and softlink to the old versions.

5) 9i dbca doesn't work out of the box.
I installed          jre-6u15-linux-i586.rpm to provide SUN java and then
edited the dbca script to reference the new java not use the old non
compatible one.

6) 9i oui couldn't detect the xml based 11gR2 inventory on the same machine
so I've got a somewhat odd inventory setup.

7) you probably don't want to run an unsupported rdbms engine on an o/s that
wasn't around when the engine was released .
