TRANSFER Installation and Management Guide

File Descriptions
The TRANSFER Environment
2–12 068837, Update 1 to 013198 Tandem Computers Incorporated
Text File
The Textfile (TEXTFILE) describes text that the TRANSFER system displays to users,
as well as keywords that the TRANSFER system accepts from users. Text items
include command keywords, error messages, the system trigger character, special
folder names, and help text.
The Textfile is not user-configurable; this file is released on the Base TRANSFER
distribution subvolume.
Character Map File
The Character Map (DTCMAPS) file defines the following:
The set of all characters for use in text (the base character set)
The set of characters for use in TRANSFER names (the name character set)
Rules for encoding the base character set
Section 9 of this manual outlines the character map.
The Character Map file is not user-configurable; this file is released on the Base
TRANSFER distribution subvolume.
The Remote Open Control File
The Remote Open Control (ROPENCTL) file is the control file used by the TWORK
servers to control network OPEN requests. When a TWORK server needs to
communicate with another node in the TRANSFER network, it first attempts to write a
control record to the ROPENCTL file. If another TWORK server is trying to reach the
same node by making an OPEN request across the network, the write of the control
record fails. TWORK instead puts an entry in the NET queue so that the request for
that node can be processed later. This prevents multiple TWORK processes from
becoming suspended on the same node if there is a network problem. When the
OPEN has completed, the control record is removed from the file.
The Network Traffic Logging File
The Network Traffic Logging (TRAFLOG) file logs how much network traffic
TRANSFER generates. The TWORK and TRECV servers write network traffic
information to a file that can be accessed to provide an ENFORM report for a given
node. Only one file needs to be created for all TWORKs and TRECVs on the node.
