OK, then this is what I would do: create some benign place for that, say,

/opt/appdynamics

Then install rpm with "--root /opt/appdynamics" option. This will force
rpm prepend all paths with "/opt/appdynamics". Instead of, say, putting
something into /usr/lib, it will put this stuff into
/opt/appdynamics/usr/lib (and will create missing paths there when
necessary). So:

rpm -ivh --root /opt/appdynamics/ [your appdynamics rpm name].rpm

After that done, you may need to describe the paths to binaries, libraries
there, say, by adding for libraries:

echo "/opt/appdynamics" >> /etc/ld.so.conf
/sbin/ldconfig -v

and adding extra paths to, say, /etc/profile...

I hope, this helps.
