RE: PERL DBI connection to Remote Oracle Database

But if sqlplus does work, it doesn't imply that DBI will. The way sqlplus resolves your connection id is different from the way Perl DBI does it.

When you use Perl DBI, make sure you have the environment variable ORACLE_HOME set to the right value (one that allows Perl DBI to find your tnsnames.ora file). Otherwise, you're going to spend days trying to figure out what's wrong.

Been there. Got the T-shirt.

Can you access this database via SQLPlus from the machine you are running Perl DBI on? SQLPlus does not work then Perl DBI will not work.
