TFRONT Pseudoterminals The TFRONT pseudoterminals are programs that act as front ends for the TRANSFER
network receiver (TRECV) processes. Like TAREQs, they run within standard
PATHWAY TCPs, typically sharing a TCP with a TAREQ and an agent requester.
They are called pseudoterminals because they, like TAREQs, communicate with the
scheduler as though the scheduler were a group of conversational terminals.
The number of TFRONT pseudoterminals defined at a node, in conjunction with the
definition of the TRECV server class, determines the number of simultaneous
incoming network operations that can be active simultaneously.
TRANSFER Network
Receiver (TRECV)
TRECV servers are allocated by TFRONT pseudoterminals to handle all incoming
network operations at the node. The TFRONT pseudoterminals also assign TRECV
servers for remote TWORK processes as needed. Configure at lease one TRECV
process for each TFRONT pseudoterminal defined.
You can assign a log file to the TRECV server class that receives messages for all types
of server activity, including messages related to serious problems encountered by this
server. The information in the log file is often required for diagnosing problems. In
addition, you can assign a debug log file to the TRECV server class that provides
additional information for error analysis. Further information about TRECV and its
log and debug log files appears in the TRANSFER Installation and Management Guide.
TRANSFER Worker Server
(TWORK)
TWORK servers are used by TAREQs to perform all local operations at the node
except for package delivery and agent invocation, and to perform the local portion of
all network operations. Configure at least one TWORK process for every TAREQ
defined at each node. You can assign a log file and a debug log file to TWORK, like
TRECV, that can help in analyzing errors. Further information about TWORK and its
log and debug log files appears in the TRANSFER Installation and Management Guide.
System Management
Server (SMSERV)
SMSERV is the TRANSFER system management server, which performs system-
management functions. SMSERV is called by TMANAGER.
Sampling Program
(TSAMPLE)
TSAMPLE is the TRANSFER sampler server, which takes samples of the TRANSFER
database and scheduler queues for system monitoring.
Name Server
(NAMESRV)
TISERV relies on the name server process, NAMESRV, for name validation and
resolution. In performing these tasks, the name server manages the name directory,
which contains the names of all correspondents, distribution lists, and folders defined
at the local node. The name server refers to this directory whenever a correspondent
refers to a local name. If a correspondent refers to a remote name, the TRANSFER
delivery system contacts the name server on the remote node when the name is being
resolved.
