How to Download MQ Client
If you want to develop applications that communicate with IBM MQ queue managers, you need to install MQ client libraries on your system. In this article, we will explain what MQ client is, what are its features and benefits, what are some alternatives to it, and how to download and install it on different platforms. We will also show you how to test the connectivity between your MQ client and the queue manager.
What is MQ Client?
An MQ client is a component of the IBM MQ product that can be installed on a system where no queue manager runs. It allows an application running on the same system as the client to connect to a queue manager running on another system, using a communication protocol such as TCP/IP or HTTP. The application can then send and receive messages from the queue manager, using the MQI (Message Queue Interface) API or other APIs and protocols supported by IBM MQ.

MQ Client Features and Benefits
Some of the main features and benefits of using MQ client are:
There are no direct connections between applications. The communication is indirect, through messages that are stored on queues owned by the queue manager.
The communication is independent of time. The applications do not have to wait for each other or be available at the same time. The messages are retained by the queue manager until they are processed by the receiving application.
The applications can be decoupled and distributed across different systems, platforms, and networks. This increases scalability, reliability, and flexibility.
The applications can assign a priority to a message, and the queue manager can deliver the messages according to their priority.
The communication is secure and reliable. The queue manager can encrypt, authenticate, and authorize the messages, and ensure their integrity and delivery.
The communication can be driven by events. The applications can use triggers, subscriptions, or notifications to react to changes in the message flow.
MQ Client Alternatives
There are other products and technologies that offer similar functionality as MQ client, such as:
RabbitMQ: An open-source message broker that supports multiple messaging protocols, such as AMQP, MQTT, STOMP, and HTTP.
Kafka: An open-source distributed streaming platform that can handle high-volume data ingestion and processing.
Google Cloud Pub/Sub: A cloud-based service that provides scalable and reliable messaging and event streaming.
Amazon SQS: A cloud-based service that provides a fully managed message queue service.
Azure Service Bus: A cloud-based service that provides a reliable and secure message broker service.

How to Test MQ Client Connectivity
In this section, we will show you how to test the connectivity between your MQ client and a queue manager using two methods: using MQ Explorer and using MQ command line interface (MQ CLI).
Using MQ Explorer
MQ Explorer is a graphical tool that allows you to manage and monitor IBM MQ resources. You can use it to connect to a queue manager and perform various tasks such as creating queues, sending and receiving messages, setting permissions, and viewing statistics. To use MQ Explorer, you need to have it installed on your system as part of the IBM MQ client installation.
To test the connectivity using MQ Explorer, follow these steps:
Launch MQ Explorer from the Start menu on Windows, or from the Applications folder on MacOS.
On the MQ Explorer window, right-click Queue Managers, and select Add Remote Queue Manager.
On the Add Remote Queue Manager dialog box, enter the name of the queue manager that you want to connect to, and click Next.
On the Connection Details screen, select the communication protocol that you want to use, such as TCP/IP or HTTP. Enter the host name or IP address of the system where the queue manager is running, and the port number that it is listening on. Click Next.
On the Security screen, select the security options that you want to use, such as SSL/TLS or user ID and password. Enter the required information, and click Next.
On the Finish screen, review your settings, and click Finish.
If the connection is successful, you will see the queue manager appear under Queue Managers in MQ Explorer. You can then expand it and view its resources and properties.
If the connection fails, you will see an error message with a reason code. You can then troubleshoot the issue by checking the network connectivity, firewall settings, queue manager status, security settings, and error logs.
Using MQ Command Line Interface
MQ CLI is a tool that allows you to perform various tasks on IBM MQ resources using commands. You can use it to connect to a queue manager and execute commands such as creating queues, sending and receiving messages, setting permissions, and viewing statistics. To use MQ CLI, you need to have it installed on your system as part of the IBM MQ client installation.
To test the connectivity using MQ CLI, follow these steps:
Open a command prompt or terminal window on your system.
Set the environment variables for MQ CLI. For example, on Windows, you can run setmqenv -s -k to set the variables for 64-bit mode. On Linux or MacOS, you can run . /opt/mqm/bin/setmqenv -s -k to set the variables for 64-bit mode.
Run dspmqver to display the version of MQ CLI that you are using. For example:
C:\Users\user1>dspmqver Name: IBM MQ Version: 9.2.0.0 Level: p920-L200813.DE BuildType: IKAP - (Production) Platform: IBM MQ for Windows (x64 platform) Mode: 64-bit O/S: Windows 10 Enterprise x64 Edition (Build 19042) InstName: Installation1 InstDesc: Primary: Yes InstPath: C:\Program Files\IBM\MQ DataPath: C:\ProgramData\IBM\MQ MaxCmdLevel: 920 LicenseType: Developer
Run runmqsc to start an interactive session with the queue manager that you want to connect to. For example:
C:\Users\user1>runmqsc QM1 5724-H72 (C) Copyright IBM Corp. 1994, 2020. Starting MQSC for queue manager QM1. AMQ8526I: Connected to queue manager QM1.
If the connection is successful, you will see a message indicating that you are connected to the queue manager. You can then enter commands to perform various tasks on the queue manager and its resources. For example:
dis q(*) where(type=local) 2 : dis q(*) where(type=local) AMQ8409I: Display Queue details. QUEUE(Q1) TYPE(LOCAL) AMQ8409I: Display Queue details. QUEUE(Q2) TYPE(LOCAL) AMQ8409I: Display Queue details. QUEUE(SYSTEM.ADMIN.ACCOUNTING.QUEUE) TYPE(LOCAL) AMQ8409I: Display Queue details. QUEUE(SYSTEM.ADMIN.ACTIVITY.QUEUE) TYPE(LOCAL) ...
If the connection fails, you will see an error message with a reason code. You can then troubleshoot the issue by checking the network connectivity, firewall settings, queue manager status, security settings, and error logs.
To end the interactive session, enter end at the prompt. For example:
end 3 : end One MQSC command read. No commands have a syntax error. All valid MQSC commands were processed. AMQ8567I: Disconnecting from queue manager QM1.
