Hi,
I don't know Oracle 10g, but I guess it is roughly similar to 9i.
And I saw that Oracle's Installer has flawed checks regarding operating system prerequisites. (Not accepting the latest version of Tru64 Unix in my case)
I don't know if your OS/Oracle combination will work, sorry.
But I know you can switch off these checks - at your own risk !!
Start Oracle Installer like this:
./runInstaller -ignoreSysPrereqs
This worked with Tru64 Unix V5.1B and Oracle Installer 10.1.0.2.0
If you decide to give it at try:
Good luck!
