From downstream machine - Check products on upstream machine, output should come to the screen % notifyme -vl - -o 36000 -h <upsteam machine> - Downstream machine, need to stop/delete|make queue/start % ldmadmin stop % ldmadmin delqueue % ldmadmin mkqueue Remaking the queue will by pass the product duplication problem In bin directory, edit ldmadmin line 634, change $cmd_line = "rpc.ldmd"; to $cmd_line = "rpc.ldmd -o 36000"; This will request old products. % ldmadmin start % ldmadmin watch Shows the products arriving to your machine. If no products are arriving then pqact can't act apon the queue.

Noop, pqact is a queue reader. It just reads the data products as they arrive.
