Make the last line of 

sub query_databases {
....
 return \%dbs;
}

[download]

Call it so: 

my $dbsref = query_databases ();

[download]

Then pass that to do_compare() 

my $result = do_compare( $dbsref );

[download]

Within do_compare() us the passed hashref 

sub do_compare {
  my $dbsref = shift;
  for my $key ( keys %$dbsref ) {
    if ($dbsref->{$key}{ORACLE1} eq $dbsref->{$key}{ORACLE1}) {
        # the same
    } else {
        # different
    }
  }
 }
