Hello All,

I have one loop and in there i am forking and calling one function which is calling DB handle defined as global variable. Below is the code. 

     foreach my $hostname (@host)
     {
         my $thr = fork();
         if($thr) {
             #parent
             push(@childsall, $thr);
             next;
         }
         else
         { 
            connecttohost($hostname);
         }
     }
      foreach my $child_pid (@childsall) {
         my $tmp = waitpid($child_pid, 0);
      }

sub connecttohost
{
   my($hname) = @_;
    my $query = sprintf("SELECT * FROM $DbName WHERE ue_id='$hname');
    my $hash_ref = $::dbh->selectrow_hashref($query);
}

dbh is defined as global variable. Now my question is how to keep global variable values in case of fork?

thanks --girija
