We have requirement, as per design, third party systems will push XML\CSV messages to IBM MQ queues, and we using Azure logic app need to consume those messages and send to Event hub.
My question is
As we dont have MQ available yet, and I am not able to give details in Azure and using Azure queues. Is there anyway we can mock like we are using MQ.
Logic app once receive messages XML can it store to Data lake instead of pushing through Eventhub(as Event hub storing message in AVRO format)
Any suggestions please.
Thanks
As suggested by Roger, you can install the developer version of IBM MQ to mock for Logic App testing.
Once the IBM MQ Queue is available, you can Send message from an on premise IBM MQ to Azure Service Bus queue and also able to Transform and Validate XML for workflows in Logic Apps.
You can refer to Connect to an IBM MQ server from a workflow in Azure Logic Apps, Transform XML for workflows in Azure Logic Apps and Validate XML for workflows in Azure Logic Apps

There is a kafka connect connector for iothub. This is available from the confluent website (https://www.confluent.io/hub/microsoft/kafka-connect-iothub). However, the iothub connector in kafka connect is archived (see https://github.com/Azure/toketi-kafka-connect-iothub) and the last commit dates from 2018-03-19.
In the meantime the plugin does not work with the current version and needs to be updated.
Is there an alternative repo available. Did microsoft stop supporting this? Is there a plan?
The Kafka connector project for communicating with IoT devices is indeed retired.
If only one-way is desired, Event Hubs does have a Kafka compatibility layer and IoT Hub message routing can be used to take advantage of that scenario.
You can reach out via Azure Support Request if you are looking for other alternatives and we can share our roadmap under NDA. When you open the Azure Ticket, reference this SO thread.
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 collect data from the LoRa node, and then gateway forward to lora server, at last, the data to the lora app server. but i cannot find the following interface.
(https://docs.loraserver.io/lora-app-server/integrate/data/)
enter image description here
You need to implement a MQTT client (or user a command-line one, like mosquitto_sub, as suggested in https://docs.loraserver.io/lora-app-server/integrate/data/) and then subscribe to the receiving topic for the specified node. The image you posted is not an interface but an example message a node will send through the topic. For the case given, appID is "123" and devEUI is "0202020202020202", so you need to subscribe to the following topic to get messages from the node:
application/123/node/0202020202020202/rx
As said, you may consume the messages through a MQTT client (there are plenty of clients for different languages), or from the command line.
Just updating from current versions.
Global integrations
Global integrations are configured through the lora-app-server.toml configuration file and are globally enabled. This means that for every application configured, the application will be published using this / these integration(s).
The following integrations are available:
MQTT
AWS Simple Notification Service
Azure Service Bus
Google Cloud Platform Pub/Sub
Application integrations
Additional to the globally enabled integrations, it is also possible to set up integrations per application.
The following integrations are available:
HTTP
InfluxDB

What is the difference between a Websphere Message Broker and a Queue Manager. I guess the queue manager puts messages in the queue, takes messages out of the queue, moves messages to backout queues etc. So what is the job of the broker?
Does it sit between the publisher and the Queue Manager or between the consumer and the Queue Manager?
Websphere MQ is a software which uses the AMQ(Asynchronous messaging protocol). You can achieve asynchronous messaging between your applications via Websphere MQ, which will make your infrastructure loosely coupled(Applications can keep working even though other applications are down in the infrastructure).
But the applications in your infrastructure may not be able to understand each others' message formats, and hence just sending the message to the target application may not be enough. You may require transformation of the message.
You can do it by writing your own program using the Websphere MQ API.
Your program should be able to do the below things:
Pick message from a specific queue (using MQGET)
Should be able to understand the message. That is say it's an XML message. Then your program must be able to parse the XML and read the
data in it.
After reading the input message you will make your output message based on the requirements.
Then you will either publish the message or put the message in some specific queue(say TargetQ), so that the target application can get
the message. Target application will then get the message either by
issuing MQGET on the TargetQ or subscribing to the topic which was
published from your application.
But writing your own program will take a lot of development time and effort and also may be a bit complex.
So, IBM provided its own software to do the job, which is "Websphere Message Broker".
WMB allows you to create programs very easily and a lot faster.
Appropriate nodes in WMB will do all above steps for you. In fact it provides lot many features than the above steps.
Websphere MQ still doesn't have an HTTP listener. But, a message broker does. It allows you to host web services and have HTTP based flows etc that too in a secure way(Supports SSL).
MQ is providing you the infrastructure for messaging: queues and topics - IBM MQ
IBM Integration Bus (formerly known as WebSphere Message Broker) allows you to apply the common EAI patterns, e.g. Routing, Transformation
Hope that helps.
Best,

I want to add just two points: Message Broker (now IIB) includes a set of optimized and fast parsers (XML, CSV, etc) and useful mapping nodes (msg-msg, msg-db). MQ is also used for internal configuration messages coming from the Configuration Manager.
WebSphere MQ is a solution for application-to-application communication services regardless of where your applications or data reside. Whether on a single server, separate servers of the same type, or separate servers of different architecture types, WebSphere MQ facilitates communications between applications by sending and receiving message data via messaging queues. Applications then use the information in these messages to interact with Web browsers, business logic, and databases. WebSphere MQ provides a secure and reliable transport layer for moving data unchanged in the form of messages between applications but it is not aware of the content of the messages. WebSphere MQ uses a set of small and standard application programming interfaces (APIs) that support a number of programming languages, including Visual Basic, NATURAL, COBOL, Java, and C across all platforms.
WebSphere Message Broker is built to extend WebSphere MQ, and it is capable of understanding the content of each message that it moves through the Broker. Customers can define the set of operations on each message depending on its content. The message processing nodes supplied with WebSphere Message Broker are capable of processing messages from various sources, such as Java Message Service (JMS) providers, HyperText Transfer Protocol (HTTP) calls, or data read from files. By connecting these nodes with each other, customers can define linked operations on a message as it flows from one application to its destination.
Message Broker can do the following:
Matches and routes communications between services
Converts between different transport protocols
Transforms message formats between requestor and service
Identifies and distributes business events from disparate sources
Together, WebSphere MQ and WebSphere Message Broker deliver a comprehensive publish and subscribe facility, connecting Message Broker’s broad transport and format support to WebSphere MQ’s messaging backbone. WebSphere Message Broker extends the WebSphere MQ publish and subscribe functionality with advanced function such as content-based publish and subscribe by means of an enhanced Publication node. The two products share a common publish and subscribe domain for topic- and content-based operations
MQ is mainly for the transforming the messages from on system to another system.
WMB(websphere message broker) will sit between QMGR's and transforming message along with change content of the message format as per the system requirement/Business Logic implementation.

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.
