I'm new to Oracle so forgive me if I don't have all the terminology down, but I've installed Oracle 10g and I'm constantly getting an "ora-12154 Could not resolve the connect identifier" error at step 12 in database configuration assistant. I beleive it has something to do with the tnsnames.ora file and I've played around with the variables but I can't get it to work.
the tnsnames file that is created, I guess by default, looks as below.
# tnsnames.ora Network Configuration File: D:oracleora101networkadmintnsnames.ora
# Generated by Oracle configuration tools.
