We have a simple SDR/RCVR channel pair with the sender being my client and the receiver a 3rd party. Client uses HPUX v11 with MQ53 csd 10. 3rd party uses windows, v53+.
Although I can start the sdr channel to RUNNING and they see the state change from INACTIVE to RUNNING on 3rd Party side, no messages seem to be getting across the channel. There are no errors on my side in any of the three locations.
Here is what I see on the channel status:
AMQ8417: Display Channel Status details.
CHANNEL(XXXX.EQLSG2Q1.C1) XMITQ(XXXX.EQLSG2Q1.X1)
CONNAME(XXXX(14016)) CURRENT
CHLTYPE(SDR) INDOUBT(NO)
LSTSEQNO(0) LSTLUWID(0000000000000000)
CURMSGS(0) CURSEQNO(12)
CURLUWID(442AAC511000020D) STATUS(RUNNING)
LSTMSGTI(10.04.17) LSTMSGDA(2006-03-30)
MSGS(12) BYTSSENT(6290)
BYTSRCVD(524) BATCHES(14)
BATCHSZ(50) HBINT(300)
NPMSPEED(FAST) CHSTATI(09.47.51)
CHSTADA(2006-03-30) BUFSSENT(27)
BUFSRCVD(15) LONGRTS(999999999)
SHORTRTS(10) JOBNAME(00000CF400000001)
MCASTAT(RUNNING) STOPREQ(NO)
LOCLADDR(XXXX(62555)) SSLPEER()
RQMNAME(EQLSG2Q1)
Note the following:
MSGS is 12
CURSEQNO is 12.
All as expected, however both LSTSEQNO and CURMSGS remain empty. The 3rd party claims that they are still seeing all the values at zero, however I can confirm that the messages are leaving my machine and also leaving our firewall.
Also, there are no messages on the DLQ at either end.
Any ideas?

While the channels are INACTIVE, put another message. If the channel stautus goes to RUNNING then something's gone across. If it doesn't, check the xmit queue.
You've clearly checked the DLQ on the target machine and found it empty; have you double checked the remote queue definition on your side to ensure it's pointing to the right place? Also that the target is not an alias & the message is being redirected?
My style of problem resolution is to eliminate the blindingly obvious problems before looking for complex issues. This is because I usually make blindingly obvious mistakes.

Are these messages non-persistent? Your channel's NPMSPEED is set to FAST so the LSTSEQNO is not incremented by non-persistent messages. Additionally the CURMSGS would only ever bee non-0 if you look at the status mid-batch of messages. IIRC non-persistent messages are not sent as part of a batch on a NPMSPEED(FAST) channel because there is no need to sync channels.
Look at the DISPLAY CHSTATUS command in chapter 2 of the MQSC command reference manual.
Since MQ doesn't assure delivery of non-persistent messages, try changing the NPMSPEED to normal so that non-persistent messages are forced into a unit of work by the channel. That way you'll see if there is a problem with the channel.

| Thanks, John. I am using amqsput on the command line. I will try what you suggest but the it still does not explain why they do not seem to be getting the message. Or have I missed something? |

How annoying. The 3rd party had there application q open for input all along. It was getting my test messages and spitting them out to another queue but not recording where they originated from!
Case closed!!!!
Thanks |
