In case it is of interest I have solved the problem like this.
package GSystem::Common::DBH;
use strict;
use warnings;
use Log::Log4perl qw(get_logger);
use DBI;
our $dbh = undef;
sub dbh {
my $log = get_logger('GSystem::Common::DBH');
my $dbusr = "user";
my $dbpwd = "pwd";
my $dsn = "GSystem";
$dbh = DBI->connect("DBI:ODBC:$dsn", $dbusr, $dbpwd, {RaiseError => 0,
PrintError => 0}) || $log->logdie ("Could not connect to database")
unless defined $dbh;
return $dbh;
}
1;
So when I want a dbh I use
my $dbh = GSystem::Common::DBH::dbh;
and I (think) I either get a new or existing dbh.
I would be interested to know of any flaws in my logic...
