When I installed Oracle 8.1.6 on Red Hat Linux 6.2 a lot of scripts in $ORACLE_HOME/bin/ didn't work.
Today I figured out that they are written for Kornshell (#!/bin/ksh), and I had to change them.
I don't use Kornshell and I don't even have it installed on my machine.
The the question is: Is Kornshell a requirement for ORACLE?
There is no requirement for the shell in Linux. I would say, go ahead and install the korn shell if the scripts are using it. There is no requirement to have a Korn Shell as the Default Shell.
The default shell can be /bin/sh, /bin/csh, /bin/ksh, or /bin/bash, but the examples assume the Bourne shell (/bin/sh).
Strange thing is that ORACLE installer never asked me anything about shells, and did not even check mine shell... Very strange... but anyway thanks, will install Kornshell.
The Korn shell is pretty standard on all Unix systems. You usually have a choice between selecting from the Bourne shell, Korn shell (not to be confused w/ the musical group), and C shells. Most software vendors, including Oracle, assume that the person installing the software on a platform at least know the basics of that platform. This isn't a knock at all - I just want to suggest that if you are running Oracle on the platform and if you don't have any experience with it (which I am assuming because you didn't install all of the shells) that you pick up a book on the OS basics and read it carefully.
You shouldn't modify the Oracle supplied scripts in bin unless you have a good reason to.
BTW:
I didn't even realize that you had a choice to not install the basic shells w/ Linux. Are you sure they aren't installed?

What interesting is that when I installed Red Hat 6.2 it never asked me for choice of shells, so I installed default set of shells.
To make sure I don't have Kornshell installed I did:
[root@mylinux /root]locate ksh
and it returned me a 20 lines of crap but not ksh, then I went to /bin and I did not find it there, so I don't have it installed.
Anyway, now I will know that I need to have kornshell installed for Oracle.

Strange...
I'll have to remember to watch out for that if I go to 6.2
