To send updates from a VM node into a non-VM system, use the :gateway tag to define a gateway service machine. The VM service machine will send all updates to this gateway machine, which in turn will transmit them by the specified protocol at regular intervals using the program FATSEND.
Valid protocols are TCPIP, BITNET and MVSJOB. TCPIP, which is the default, results in the files being transferred using the CSPACK routines, as described above. One should normally also set the :receive.yes option so that updates are also retrieved from these remote systems.
Specfiying BITNET together with a gateway machine permits updates to be sent to remote nodes at specified intervals, rather than immediately.
Although it is possible to use SENDFILE to send files to MVS nodes, these files are generally unreadable and hence the preferred method is to specify the protocol MVSJOB. This will result in an IEBGENER job being submitted to the remote node, which will copy the updates to a temporary file in the input queue of the specified server. The usual restrictions on remote job submission apply.
