Hi,
I m using mqseries using java. My sender channel is at different location and reciever is at different location.
I want to know at sender side whether reciever channel got the data or not.
Is there any method using which sender will get the acknowledgement from the reciever.
thnx in adv.
regards,
ritesh  |

| Try searching here for COA and the manual is either the application programming guide or reference. However, I'd suggest you look at both. |

hi all,
thanks a lot for all ur suggestions.
here is my scenario
i m having sender qmgr in which i have create one remote queue and one transmission queue, i have created one svrconn channel and one sender channel.i have developed separate application for accessing sender qmgr and sending data.
at receiver side i have create one receiver qmgr, queue and one receiver channel for receiving data. all are created using wsmq explorer. i m having one java application for reading the data from mqseries.
now my question is where to use COA/COD. whether it is at sender side or receiver side. i searched the forum but i m not getting how and where to use this.
pls don't mind as i m new to mqseries.
regards,
ritesh |

You specify the COA/COD options before sending the message.
So it is the sender side that specifies these options.
Enjoy  |

hi,
this is what i m doing at sender side.
qMgr = new MQQueueManager("sender");
int openOptions = MQC.MQOO_OUTPUT +MQC.MQOO_FAIL_IF_QUIESCING;
MQQueue myQueue = qMgr.accessQueue(remote_queue, openOptions, null, null, null);
MQMessage myMessage = new MQMessage();
myMessage.messageType = MQC.MQMT_REPORT;
myMessage.report = MQC.MQRO_COA ;
myMessage.feedback = MQC.MQFB_COA;
myMessage.replyToQueueName = "feedback";
myMessage.replyToQueueManagerName =(String)vecQueueInfo.get(3);
myMessage.messageId = null;
myMessage.correlationId = null;
myMessage.groupId = null;
strData = "test";
myMessage.writeString(strData);
myMessage.format = MQC.MQFMT_STRING;
MQPutMessageOptions pmo = new MQPutMessageOptions();
pmo.options = MQC.MQPMO_LOGICAL_ORDER | MQC.MQPMO_SYNCPOINT;
myQueue.put(myMessage, pmo);
qMgr.commit();
myQueue.close();
qMgr.disconnect();
i m getting reason code 2027 exception.
regards,
Ritesh |

Wait a sec, can I first ask why you want to do this?
Way I see it, it's quite simple; say you sent a message, and it's persistent - if it's still in the xmitq, it hasn't been sent, if it isn't, it has been sent. This is WMQ we're talking about, assured delivery and all.
So unless you have a buisness requirement to have CODs (as some sites do) I would not recommend investing time doing this. Moreover, by the fact you wrote "urgent" I deduce that this has more to do with some malfunction you're having, and not some robust solution, so we're probably going about this the wrong way.
Please restate the exact scenario - what's the prob, what you want to do and why. |

That's because you did not specify a ReplyToQ, as is written quite clearly in the manual. Listen, urgent or not, we cannot write your code for you, or read the manual for you; it seems that you do not understand CODs at all, otherwise you wouldn't have forgotten ReplyToQ...
If this is indeed the solution you want, read the manual, search this site (when I searched I found Report Message which is quite exhaustive), and find samples on the internet to help you code; most importantly, accept the fact that all this will take you at least a few days. |

You mean the database from which you take the data that should be sent? If so, just update it as "sent" after you get an MQRC_NONE from your MQPUT - again, this is WMQ, assured delivery is guaranteed. |

Wow there! hold your horses!
Could you, for the sake of future generation and the health of mind of those that helped you, fill in the gaps between "I have a prob" and "it's over"? What was the initial problem? How did you solve it?
I'd personally much appreciate it |
