Go to a machine that has internet connections and is the same platform as you are on. Use PPM to download (but not install) DBI and DBD::Oracle. Move them to your machine and install them. You may need to set your PPM repository to some directory at http://www.esoftmatic.com/ which has good windows binaries of DBI stuff. You'll have to set some environment variables, read the DBD::Oracle docs and check the archives of dbi-users@perl.org for details. Good luck!
