About compat-libstdc++-33* installation

[Nicosia Gaetano]

Hi to all,

I have installed RHEL 6. Because I must to install Oracle DB 11g, I need 
the packages compat-libstdc++-33*

But when I run the command rpm -Uvh compat-libstdc++-33*, more errors 
errors are displayed like this:

 >> libc.so.6 necessary to compat-libstdc++-33-3.2.3-69.el6.i686

How can solve this problem ?

Thank You and Best Regards
Gaetano
