Difference like this, where cgi & perl scripts work fine, but mod_perl/ASP
doesn't, often has to do with %ENV where mod_perl is concerned.
This is because Apache clears %ENV. The best way I have found to know
what is in your %ENV for Oracle connections is to explicitly set it
before the connect like:
$ENV{'ORACLE_HOME'} = '/path/to/oracle/home';
$ENV{'NLS_LANG'} ='american_america.WE8ISO8859P1';
$ENV{'ORA_NLS33'} = $ENV{ORACLE_HOME}.'/ocommon/nls/admin/data';
DBI->connect('dbi:Oracle:' ...);
This likely has nothing to do with Apache::ASP
You can also try PerlPassEnv & PerlSetEnv for things like the
above, but explicitly setting has always given me the most mileage.
