LIBTUX_CAT:489: ERROR: Performed tpreturn() with outstanding replies

Question

Hi all,
We have three asynchronous call (tpacall with flags TPNOTRAN).
Service A:
tpacall(TPNOTRAN) Service B -> tpcall Service X
tpacall(TPNOTRAN) Service C -> tpcall Service Y
tpacall(TPNOTRAN) Service D -> tpcall Service C
If one call returns fails, we use tpcancel for the other services, but in the ULOG we can see:
LIBTUX_CAT:489: ERROR: Performed tpreturn() with outstanding replies
It is possible to know what are the outstanding replies?
Thanks in advanced

Hi,
I think you are referring to the documentation for error LIBTUX_CAT:1286, which suggests tuning the kernel parameters as a more general solution. The explanation for LIBTUX_CAT:669 is more specific (earlier messages in the ULOG usually give a more specific reason for the problem):
+669 ERROR: Message operation failed because of the invalid message queue identifier+
Description
msgsnd to a queue failed because of invalid message queue identifier. This can also occur if a request is made by a client who exits before the request is satisfied. The cleanup after the client exits removes the message queue.
Action
Check the message queue identifier in msgsnd(). The message may be corrupted. Contact your ORACLE TUXEDO system Technical Support.
Increasing the kernel parameters will not help in this case, as the problem is due to the queue having been removed, which happens when the client program terminates, and it is quite likely that there will be no messages in the ULOG indicating what happened. You will need to follow the suggestions made earlier in this forum thread and find out what happened to the client.
