Sending Ack with Multi-Server

[Marcus de Leon]

Hi,

When I try to send an ACK back through a TCP/IP multi-server with the MLP PDL, it doesn’t work. If I switch it to Server it works.

Any Ideas?

Thanks,

Marcus

Marcus,

You need to include some additional code in the ACK proc to tell Cloverleaf which port to send the ack back on, since there are multiple simultaneous connections.

Your ACK proc has to be setup properly in order for ACK’s to be returned.  You’ll need something like the following:

           # If multiServer, the following metadata must be set

           if { $multiServer } {

               msgmetaset $obMsg DESTCONN [msgmetaget $mh ORIGSOURCECONN]

               msgmetaset $obMsg SOURCECONN [msgmetaget $mh DESTCONN]

               set driverCtl [msgmetaget $mh DRIVERCTL]

               keylget driverCtl CONNID connID

               keylset connIDKey CONNID $connID

               msgmetaset $obMsg DRIVERCTL $connIDKey

           }

           msgset $obMsg $ACK

I use the same ACK proc for both server and multi-server.  I just use an argument of {MULTI 1} to trigger the code for multi-server ack’s.

Hope this helps!
