Okay. I just uninstalled and deleted all traces and reinstalled ActivePerl & DBI & DBD::Oracle and I had no trouble getting my "use DBI;" to work. Now I've hit the next bit of ignorance. I've got Toad. Toad is accessing all of the Oracle dbs in the tnsnames.ora file just fine. When I check for Oracle data sources I get nothing. Can anyone advise me on how to inform my script whatever it needs to know in order to avail itself of the network Oracle sources? Thank you.
