Hi,

Remember that you must have installed the oracle libs in order to compile the DBD::Oracle module.

And when using the module, if it don't work, normally it's because you need to set the ORACLE_HOME environment variable, e.g:

use DBI;

$ENV{ORACLE_HOME} = '/usr/local/oracle/OraHome_1';

# Database connection data
my $dsn = "DBI:Oracle:host=$host;sid=$sid";
my $user = 'luser';
my $password = 's3c3t';

my $dbh = DBI->connect($dsn, $user, $password)
   or die "Can't connect: $DBI::errstr";

...

If the Oracle database is an old version and you don't find anywhere the Oracle libs, to compile the DBD::Oracle, you can go with the Java JDBC via JDBC, of course you need the .jar file containing the Java JDBC, but this is very simple to get.

PS: By the way, RTFM
