Skeeve:

mje has it right, you just can't do it that way. However, you could have multiple connection strings. Try the first one, and if it fails, move on to the next one. Stop when you get one that works. Something like the following (untested and probably dreadful):

use DBI;
my $dbh;
my @DSNs = [
   { DSN='blah1', UID='user1', PWD='password1' },
   { DSN='blah2', UID='user2', PWD='password2' },
];
=DBI->connect("dbi:Oracle:host=host1.my.do.main;sid=MYDB","me","secret
+");

my @DSNs = [
'blah1', 'blah2', 'blah3');
for my $hr (@DSNs) {
   $dbh = DBI->connect($$hr{DSN}, $$hr{UID}, $$hr{PWD});
   last unless defined $dbh;
}
