The 8.1.6 install is not compatible with the version of libc that comes with RedHat 7. The version of libc that comes with RedHat 7 is supposed to be backwards compatible at run-time, however because of the relinking process Oracle goes through it breaks.

I would suggest you copy over the binaries and libraries from your working Redhat 6 box. This is normally not recommended however in this case it's *exactly* what you want.

If you can't do this you could try following these instructions. They amount to downloading the libraries and link tools you used on Rehat 6 to your new box and using them there. The result should be exactly the same as simply copying the binaries and libraries from the old box.

The Redhat bug ("tar" in Oracle-speak) that tracks this issue is at:  http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=18391

It was decided it's an Oracle problem however. As long as Oracle's installation process includes a relink phase it will continue to be tied to specific versions and have compatibility problems.
