Explanation
VTAM® has
a write-to-operator with reply (WTOR) message
msgid to
send to the program operator application (POA)
poaname,
but a reply ID is not available for this
poaname.
This can occur for either of the following reasons:
- The POA is not issuing RCVCMD macros quickly enough to receive
outstanding WTOR messages.
- The outstanding WTOR messages have been received by the POA, but
replies have not been received by VTAM.
poaname is the name of the POA that
is to receive the VTAM message.
msgid is
the ID of the failing message.
System action
Message msgid and all subsequent
WTOR messages will be rerouted to the system console until a reply
ID becomes available for this poaname.
Operator response
- Issue DISPLAY ID=poaname and save the system
log for problem determination. Message IST271I will provide the jobname related
to the poaname.
- Request a dump of the application program (jobname)
and VTAM for problem determination.
System programmer response
- If the POA is not issuing RCVCMD macros quickly enough, you can
clear the VTAM message queue
for poaname by issuing RCVCMD macros with OPTCD=NQ
until the queue is empty.
- If RCVCMD macros are being issued quickly enough, examine the
dump and the VTAM internal
trace (if available) to determine why the messages are not being received
or responded to quickly enough.
- The POA must issue a SENDCMD macro to send a REPLY command to VTAM for each of the outstanding
WTOR messages. Check to ensure that the RCVCMD and SENDCMD macros
are being received by VTAM.
- You might need to change the POA RCVCMD processing so that RCVCMDs
are issued more frequently.
- You can also change the dispatching priority of the POA. See your
operating system documentation for information on dispatching priority.
- You can cancel the job related to poaname.
This will clear the VTAM message
queue for poaname.

RCVCMD and SENDCMD macros, and VTAM reply
IDs.
