Handling a TRANSFER
Network
Two features help you handle traffic between nodes in your TRANSFER network.
You can determine how much network traffic TRANSFER generates, and you can set
the priority for your EXPAND line.
Network Traffic Logging
The TRANSFER TWORK and TRECV processes can write network traffic information
to a file, which can then be accessed to provide an ENFORM report for a given node.
For TWORK, one record is written to the traffic log file for every system to which the
process tries to transport an item. A Y in the SUCCESS field indicates that the send
was successful; an N indicates it needed to be postponed.
For TRECV, one record is written to the traffic log file for each open and close
combination by a remote TWORK. Success is indicated when the TRECV submits a
package on the top-level item.
The Traffic Logging File. The file generated by the servers contains the following
information:
Start time of item transport
The start time (START-TIME) is the time that the server began processing the
specified item.
Destination or source node
The destination or source node (NODE-NAME) is the EXPAND node name of the
node where the item is going to or coming from.
Transport direction
The transport direction (DIRECTION) helps to determine which type of server is
processing the item. An I indicates inbound for a TRECV; and O indicates
outbound for a TWORK.
Type of work
The type of work (TYPE-OF-WORK) helps determine whether this transport is for
package submission or package cancellation. An S indicates ship; a C indicates
cancel.
Process name of process making the entry
The process name (PROCESS-NAME) is the process name of the process making
the entry. This is used to help make the key unique.
Current top-level item ID
The ITEM-ID field helps identify the package that is being transported. If there are
component items, they are added to the transport, but only the top-level item is
identified.
