TRANSFER Server
Messages
TRANSFER servers write various types of messages to their output files; these files are
defined in the PATHWAY configuration. The server output files can be examined for
errors that have occurred and for purposes of tracking the activity of the TRANSFER
servers.
Any server that detects a problem with a file writes an error message to the output file
indicating the error and the file name and gives a trace of the P register (calling
sequence).
If TISERV, TWORK, or TRECV is having difficulty communicating with TSCHED, the
server continues and schedules its events independently of TSCHED. In this situation,
TISERV, TWORK, or TRECV writes the following message to its output file:
Error xxx attempting communication with TSCHED. Continuing
TISERV Error Messages Attempts to break the TRANSFER security for establishing sessions can be monitored
by examining the output file for the TRANSFER interactive server (TISERV). When a
correspondent repeatedly enters an incorrect password, a message is written to the
TISERV output file specifying the depot (correspondent name) for which the security
violation occurred.
TWORK Error Messages TWORK generally writes messages to its output file in the following format:
xxxx failure: nn/nn
The variables in a TWORK message indicate the name of an internal routine, a
TRANSFER error code, and a detail code. If the error is anticipated by TWORK,
TWORK generates the appropriate TAREQ event package; otherwise, TWORK returns
an error to the TAREQ that invoked the TWORK.
One TWORK warning message that you can get is the following:
Concurrent open of remote name disallowed
TRANSFER allows the TWORK process to do only one OPEN to a remote node at a
time. TRANSFER lets multiple paths be open, but they cannot be in the process of
opening concurrently. As soon as one OPEN is open, another OPEN can begin.
TRECV Error Messages TRECV writes messages to its output file in the following format:
xxxx failure: nn/nn
The variables in a TRECV message indicate the name of an internal routine, a
TRANSFER error code, and a detail code. If the error is anticipated by TRECV,
TRECV generates the appropriate TAREQ event package; otherwise, TRECV returns
an error to the TWORK that invoked the TRECV. When TRECV returns an error to
TWORK, TWORK either passes the error to the TAREQ that invoked the TWORK or
informs TSCHED that the network operation is to be rescheduled for later processing.
