How do I send multiple messages to Websphere MQ from HERMES JMS Application in one go?
I was successful in sending a single message, as soon as I process 2 or more messages to the Hermes application it fails.
If you are not stuck with HermesJMS you could give a try to JMSToolBox (on sourceforge) where you can manage "scripts" to post multiple messages to various destinations

I'm newbie on IBM products, and I would like to know what would be the best approach to achieve the following integration solution:
A third party application that uses only AMQP to exchange messages, will put a message on an inbound queue (managed by IBM MQ)
IBM integration bus(version 10) flow will retrieve that message
Parse the message and invoke a rest api, get a response.
Parse the response, and send it back to the output queue so the third party can consume it.
My MQ colleague (amqp in new for him) created the corresponding "AMQP queue manager; channel and topic" using IBM MQ 9.0.4, and provided me of the connection info.
In my understanding I thought about creating a flow that will use "MQInput node" that will connect to the queue used by the third party to drop the message, and continue my processing.
Unfortunately I’m not able to connect to that AMQP channel, neither using: The "MQInput node" on IIB v10 Nor using "MQ explorer"
I strongly believe I miss something in that integration solution: either on the mq side or on the iib side, but not able to know what.
The challenge is to know, in order to achieve the above scenario, does the component IBM MQ and IBM Integration bus are enough, or I'll some other components?
Any documentation or tutorial that could describe/explain such scenario?
I am newbie to Websphere MQ and i have some basic understanding on the concept of MQ. I know that MQ client would create a message (with MQMD and application data) and then send to MQ manager. MQ client will get the correct response back from MQ Manager. Supposedly there are many messages on the MQ Queue Manager, how does MQ client able to retrieve the right messages? What determines the uniqueness of a MQ message?
There are different ways this can be approached - one common way is for the applications processing the messages to use the message ID and correlation ID fields. The message ID can be randomly generated and saved then copied to correlation ID field to be match when the reply is sent. Applications can do gets matching on those fields in the message header.
I suggest you read through the application programming guide and reference in the knowledge center.
i am very new to WebSphere MQ someone please tell me how to see header portion of message in WebSphere MQ (7.0.1.3)
/opt/mqm/samp/bin/amqsbcg on linux can browse the messages for you. It prints the message header as well as the content. But you have to be on the same server as MQ qmgr.
If you are on a mq client, /opt/mqm/samp/bin/amqsbcgc should do, but you need to use a svrconn channel to connect to the qmgr and browse the messages.
I'm new in using Websphere MQ. I need help in this.
I have a websphere located in a server remotely and I have an application that retrieves and sends the information to the websphere. Is it possible to send my queue to a remote websphere server and at the same time retrieve it? It's something like this.
If yes, how should I configure this one in the websphere remote server? Thanks!
Sorry to say your question is confusing. You don't send/receive queue. You send/receive messages to queue or topic. Can you clarify?
Update:
You can have WebSphere MQ queue manager running on machine and client application on different machine. Application can send and receive messages to/from remote queue manager. This is called as the client mode connection to queue manager and most commonly used type of connection mode.
Please read the WebSphere MQ InfoCenter.
I have a program which publishes data to IBM Websphere MQ via the MQAX200 interface. I'm struggling to work out how to test it.
What's the simplest way of setting up an application to consume the messages from the queue and confirm they're correct? I don't currently have any MQ infrastructure here (that's on the client's site).
Do I need a message broker? Are there any open source implementations? Or do i need to purchase Websphere MQ, in which case what's the minimal license I'd require?
Thanks
Ben
As your application is written using a MQ interface, you need MQ to test. If it's just for testing, you can use the trial version of MQ.
As far as I know MQAX200 interface supports only P2P messaging and not Publish/Subscribe messaging. So using your application put message to a queue and then use the application like amqsgetto receive message.
You don't need message broker.
First, you need to clarify what it is you are trying to do. If you are publishing messages then your test program will need to subscribe. If you are putting messages into a queue then your test program will need to GET messages from the same queue.
The WMQ Trial Download will get you a 90-day WMQ license for no charge. The trial code includes the server and the client libraries so you can set up a QMgr and then test your program in client or bindings mode, as appropriate. If you elect to install the sample code you also get compiled binaries with which you can test. For example, amqsget gets messages and amqssub subscribes to topics, both using bindings mode (shared memory). The client versions of these (amqsgetc and amqssubc) attach over the network. If you are using topics, make sure to subscribe before you publish. If using queues, make sure to GET after you PUT.
Other useful programs include amqsgbr to browse messages on queues and amqsbcg which will hex-dump the messages and parse the message headers. Also, WMQ Explorer comes with the Windows and Linux versions of the trial and you can use that to browse, subscribe or get messages.
Just write a simple Java JMS program that subscribes to the Topic. THen you only need to install the free WebSphere MQ Client.
