Administering a queue manager using MQ Explorer and the runmqsc command line

This guide documents how to adminster an IBM MQ on Cloud queue manager using the MQ Explorer application and the runmqsc command line interface.

MQ Explorer:

MQ Explorer is an Eclipse-based tool for administering IBM MQ that you install on a machine of your choice and which connects remotely to one or more queue managers using a client connection. There are native installers for Windows and Linux 64-bit environments and it can be run on Mac OS via a Docker container as described in the prerequisites below.

The Eclipse plugin for MQ explorer on Mac OS does not, at the time of writing, support TLS connection. The administration channel for MQ on Cloud queue managers newer than version 9.2.1 revision 1 will have TLS enabled. These should be administered from Linux or Windows.

runmqsc

Part of the "MQ clients" bundle, runqmsc is a command-line interface (CLI) tool that allows you to automate the configuration of MQ queue managers by executing a series of pre-defined steps at the command-line or in a script file. It is supported on a range of operating systems including Windows and Linux (but is not currently supported on Mac OS).

There are many actions you can perform by using MQ Explorer or runmqsc from an MQ client. You can

  • Connect to a queue manager
  • Create a new queue
  • Put a message onto a queue
  • Delete a queue

In addition to this, on MQ Explorer, you can browse a queue to view messages In the runmqsc command line, you can also get messages from a queue

Before you begin

  • An existing installation of IBM MQ Explorer. Download and installation instructions for Windows and Linux can be obtained from here and for Mac OS from here. or
  • An existing installation of IBM MQ Client on your own machine.
  • Download the client from here.
    • Clicking the HTTP link next to the latest available version of the CD Clients will take you to Fix Central. From there you can search for and select the appropriate Redist (redistributable) client bundle for your operating system platform. This will include the sample applications and runmqsc.
    • Once downloaded, unpack the bundle into a location of your choosing.
    • Make a note of the full path to the bin directory, the location of which will depend upon where you chose to unpack the bundle. This path will be referenced as <PATH_TO_BIN_DIR> for the rest of this task.
    • Make a note of the full path to the directory containing the sample applications. This path will be referenced as <PATH_TO_SAMPLE_BIN_DIR> for the rest of this task.
      • For Windows, this will be the bin directory unpacked in the previous step, the location of which will depend upon where you chose to unpack the bundle.
      • For Linux, this will be the samp/bin directory unpacked in the previous step, the location of which will depend upon where you chose to unpack the bundle.

Gather required connection details

  1. Log in to the IBM Cloud console.

  2. Click on the 'hamburger menu'.

  3. Click Dashboard.

    • Ensure that RESOURCE GROUP is set to All Resources.

  4. Locate and click on your IBM MQ service instance, found under the 'Services' heading.

  5. From the list of your queue managers, click on the one you want to administer.

  6. Make note of the Queue manager name, Hostname and Port values for use in the next steps.

  7. If you already know your MQ Username and IBM Cloud API Key, you can skip to the next section of this task. Otherwise, Click the Administration tab.

  8. Make a note of your MQ Username for future use.

  9. If you do not already have an existing IBM Cloud API key:

    • Click Create IBM Cloud API Key.
    • Click Show to display the API key to copy and save it for later, or click Download to store the API key in a file.
      • Note that the API key generated in these steps is used to authenticate with IBM Cloud as the user who created it. Therefore, it should not be shared with any other users and should be stored securely.
      • An API key created through the IBM MQ service can be reset from the queue manager Administration tab.
    • Click Close.

Connect to your queue manager

Using MQ Explorer:

  1. Start IBM MQ Explorer.

  2. In the 'MQ Explorer - Navigator' panel, expand IBM MQ.

  3. Right click Queue Managers.

  4. Click Add Remote Queue Manager....

  10. Click Next.

  11. Click Next.

  12. Tick the checkbox for 'Enable user identification'.

  13. Untick the checkbox for 'User identification compatibility mode'.

  14. Type your MQ username as the user id.

    Image showing the complete username fields

  15. Click Finish.

  16. Paste your platform API key into the 'Password' text box.

  17. Click OK.

Your queue manager connection now appears under the Queue Managers folder in the 'MQ Explorer - Navigator' panel.

Using runmqsc

  1. Open a command shell to use in the next steps.
  2. Export the 'MQSERVER' variable:
    • Linux: export MQSERVER="CLOUD.ADMIN.SVRCONN/TCP/<Hostname>(<Port>)"
    • Windows (Command prompt): set MQSERVER=CLOUD.ADMIN.SVRCONN/TCP/<Hostname>(<Port>)
    • Windows (PowerShell): $env:MQSERVER="CLOUD.ADMIN.SVRCONN/TCP/<Hostname>(<Port>)"
  3. Run <PATH_TO_BIN_DIR>/runmqsc -c -u <your MQ username> -w60 <QUEUE_MANAGER_NAME>
  4. Enter your platform API key when prompted for a password.

Create a new test queue called 'DEV.TEST.1'

Using MQ Explorer:

In the 'MQ Explorer - Navigator > IBM MQ > Queue Managers' view:

  1. Expand the entry for your queue manager.
  2. Right click Queues.
  3. Select 'New' > 'Local Queue...'.
  4. Type 'DEV.TEST.1' in the 'Name' text box.
  5. Click Finish.
  6. Click OK.

Your new queue appears in the list of queues.

Using runmqsc

Queue names should start with DEV.* (example: DEV.myQueue) as application users have been configured with access to this prefix only.

In the same shell used in the previous steps:

  1. Run DEFINE QLOCAL(DEV.TEST.1)
  2. Run DISPLAY QLOCAL(DEV.TEST.1)
    • Details of queue 'DEV.TEST.1' are displayed.
  3. Run end
    • The runmqsc session is closed.
    • Retain the prompt to use in the next steps.

Put a message onto the test queue

Using MQ Explorer:

  1. Right click on queue 'DEV.TEST.1'.
  2. Click 'Put Test Message...'.
  3. Type in a test message in the 'Message data' text box.
  4. Click Put message.
  5. Click Close.
  6. Click Refresh in the 'Queues' panel.

You can see that the 'Current queue depth' for 'DEV.TEST.1' is now 1.

Using runmqsc:

We will make use of the sample program amqsputc to assist in putting messages on the test queue. In the same shell used in the previous steps:

  1. Export the 'MQSAMP_USER_ID' variable:
    • Linux: export MQSAMP_USER_ID="<your MQ username>"
    • Windows (Command prompt): set MQSAMP_USER_ID=<your MQ username>
    • Windows (PowerShell): $env:MQSAMP_USER_ID="<your MQ username>"
  2. Run <PATH_TO_SAMPLE_BIN_DIR>/amqsputc DEV.TEST.1 <your QMGR name>
  3. Enter your platform API key when prompted for a password.
  4. Type in a test message.
  5. Hit Enter twice to exit the amqsputc sample.

Browse a message on the test queue

This step is unique to MQ Explorer and cannot be achieved using the command line.

  1. Right click on queue 'DEV.TEST.1'.
  2. Click 'Browse Messages...'.
  3. Confirm you can see your test message and then click Close.

Get a message using the amqsgetc sample program

This step is unique to runmqsc and cannot be achieved on MQ Explorer.

In the same shell used in the previous steps:

  1. Run <PATH_TO_SAMPLE_BIN_DIR>/amqsgetc DEV.TEST.1 <your QMGR name>
  2. Enter your platform API key when prompted for a password.

Your test message is displayed.

After a short period, the amqsputc sample program should end after finding no more messages.

Delete the test queue

Using MQ Explorer

  1. Right click on queue 'DEV.TEST.1'.
  2. Click 'Delete'.
  3. Click 'Delete'.
  4. Check the 'Clear all messages from the queue' box.
  5. Click Delete.
  6. Click OK.

You can see that queue 'DEV.TEST.1' has been removed from the list of queues.

Using runmqsc

In the same shell used in the previous steps:

  1. Run <PATH_TO_BIN_DIR>/runmqsc -c -u <your MQ username> -w60 <QUEUE_MANAGER_NAME>
  2. Enter your platform API key when prompted for a password.
  3. Run DELETE QLOCAL(DEV.TEST.1)
    • You receive a message stating that the queue has been deleted.
  4. Run DISPLAY QLOCAL(DEV.TEST.1) to prove the queue has been deleted.
    • You receive a message stating that the queue was not found.
  5. Run end
    • The runmqsc session is closed.

Conclusion

You've successfully:

  • Connected to a queue manager using either MQ Explorer or runmqsc and have created a new test queue
  • Put a test message onto the test queue
  • Either browsed the the test queue to view the test message or used amqsgetc to view the test message
  • Cleared and deleted the test queue to clean up
