Hi ,
I have a synchronous message flow set-up where by the reply is sent via queue manager aliases.While putting the reply back i am getting an 2058
The reply final needs to be sent to a queue named A1 under queue manager A.
The response application is connecting to queue manager C and tryng to put the message to Queue A1 , Queue Manager A .We have an qmgr alias named A under queue manager C and the Setup between A and C are perfectly fine .
But when my application Connects to Queue manager C and tries put an response back it gets and error 2058. Is it that for such instances where by the actual queue manager to which the message needs to be sent is not the one to which the application is connected do we need to make any special changes in java code. ??
Please advise!
bits of my code are as mentioned below :
MQEnvironment.hostname=hostname;
MQEnvironment.channel=channel;
MQEnvironment.port=Integer.parseInt(port);
mqqueuemanager = new MQQueueManager(qmanagername);
.
.
.
.
int openOptions = MQC.MQOO_OUTPUT;
queue = mqqueuemanager.accessQueue(qname,
openOptions,
null,
null, // no dynamic q name
null); // no alternate user id
MQMessage objMQMessage = new MQMessage();
objMQMessage.writeString(message);
objMQMessage.replyToQueueManagerName = "TEST";
objMQMessage.replyToQueueName="SampleQueue";
MQPutMessageOptions pmo = new MQPutMessageOptions();
queue.put
queue.put(objMQMessage, pmo);

Why a queue manager alias called A? Why not a transmission queue?

Thanks for the prompt response.
I would just like to elaborate a bit more ..
The synchronous reply messages pass through an an hub and spoke set-up before finally reaching Queue A1 under Queue manager A.
say for eg: message is put in QMGR C it goes to QMGR D then To QMGR B and then Finally it reaches QMGR A
and each of the QMGR's C , D and B have an queue manager alias and Qmgr A has an Local queue.
Could you please advise me as to what is that i am doing wrong out here .
LIke i said ealier do i need to change my java code in such a scenario where by though the messages are put for QMGR A but the application is actually connecting to QMGR C.

If the client is connecting to C then it must specify C in the connection information or you'll get a 2058.
The queue manager alias is a routing construct once the message has been put.

Clients only need to specify a queue manager name if they are using a client connection table.
If they are specifying host/channel/port, it's usually a waste of effort to specify qmgr name. As, among other things, it leaves you open to 2058s that you would otherwise not worry about.

Well if i don't mention the queue manager name then the application will look for the queue A under queue manager C and i would get an 2085.

THanks again for the quick response.
Well if i mention the queue manager name C how will mention the message reach actual Queue A1 and queue manager A which has been picked up from the reply to Q and reply to Qmgr field of the request message.

There's a difference between mentioning the Queue Manager on the MQCONN and mentioning a different Queue Manager on the MQPUT.
And in the case of an application that is sending replies, you should always be getting and honoring the ReplyToQmgr field from the message, and not anything else.

In order to become a programmer, rather than merely someone who writes code, you will have to learn how to answer these questions yourself.

A very polite way of Jeff to point you to the documentation link at the top of the page. Read the Using Java manual....
