VTCPD Status and Exception Conditions Reference
The following table lists the status and exception conditions and their messages.
Status and Exception Conditions Messages
Error Message Description
ertimeout
The host did not respond to a VTCPD message request within the
interval set by the enquiry/response timer. See VTCPD Message
Timing on page 96.
getfail
The application could not get a VTCPD connection to the host — the
specified pool or the common pool is full. See Specifying the Host
Connection on page 81.
gotres
The application successfully connected to the host. Condition data
associated with gotres contains the connection number, the slot
number, and the port number. This data can be used to route
messages (see Using the VTCPD Port Number on page 91).
hostdown
The application requested a host connection but VTCPD does not
have any host connections. The application also receives hostdown
if the host process terminates.
If VTCPD is in UPD mode, the application does
not receive hostdown. The application only
receives hostdown if VTCPD receives a
corrupted message from the UPD host.
hostfail
VTCPD can not allocate memory, or some other internal problem.
hostup
VTCPD can be configured to send hostup to the application when
the host process restarts (vtcpd -mu). By default, applications
ignore hostup. However, the applications can be set to wait for
hostup rather than looping when the host goes down.
inf
The string from the host is not large enough for the message ID.
intertimeout
The host did not respond to a VTCPD message request within the
interval set by the intermediate timer. The application speaks a
“Please hold on” message and the intermediate timer restarts. See
VTCPD Message Timing on page 96.
invreq
1) application requested a host message and VTCPD has not
established a message ID.
2) application specified a connection that is not in the valid range
3) the application sent a message that is not long enough for the
message ID — the length of the message must not be less than the
length of the message ID plus the position of the message ID (see
Sending Messages on page 84)
unexdata
VTCPD is configured for asynchronous data delivery or notification.
See Asynchronous Replies and Reply Notification on page 89.
