Cause of the Problem
Oracle tries to open the shared object file libXp.so.6 but it could not find any. In RHEL 4 and from fedora core release (1,2,3,4 ....) "libXp.so.6" is deprecated and as such, the "xorg-x11-deprecated-libs" package is missing.

If available, then "libXp.so.6" should be found in the /usr/X11R6/lib64 directory of Linux.

On disk 2 of the linux installation CD "libXp.so.6", is available under rpm package,

xorg-x11-deprecated-libs-6.8.1-12.i386.rpm

Solution of the problem
Install the missing "xorg-x11-deprecated-libs" package.
1)Issue the following command to be sure whether libXp is missing,
$ rpm --query --whatprovides 'libXp.so.6'

or by,
$ rpm --query --whatprovides 'libXp.so.6'
2)Install the package by,
# rpm -ivh xorg-x11-deprecated-libs..rpm

Examples of rpm packages containing libXp.so.6 are,
xorg-x11-deprecated-libs-6.8.1-12.i386.rpm,
xorg-x11-deprecated-libs-6.8.2-31.i386.rpm
