Ok. Since you installed AOLserver 3.4 instead of the 3.3+ad13 tarball, you have to make sure you get the other modules, including the oracle driver. Here's what you need to do:
Yes i have got the ora8.so and ora8cass.so in the aolserver bin directory. i installed it from the uncompressed aolserver-3.3 ad 13 version. also im using nsd-oracle as the script.
in nsd.tcl
set serverroot "/home/${user_account}/web/${server}"
set pageroot ${serverroot}/www
