Postcard - Using Two Queue Managers

Skip to main content

So, you've already started Postcard with a nickname, which we'll call "Will", and you want to send a postcard to another nickname on a second queue manager on this, or another, computer.

  1. Start the second Postcard, choosing either..

  2. When the sign-on dialog appears, enter your second nickname (which we'll call "Tim").

  3. Now, on the Postcard on Will's computer, fill in the To field with your second nickname (Tim), and in the On field put the queue manager name of the second postcard where Tim is (if you don't know this name, on Tim's computer in the Postcard look below the Message box after "On:"; alternatively if both queue managers are in the default configuration cluster you can just type in the short TCP/IP name of Tim's computer and Postcard will build that into the queue manager name in the same way that the create default configuration wizard did).

  4. Type your message in, and click the Send button. Look in Tim's Postcard to see the message arrive, and double-click on it to see the postcard itself.

  5. Now try sending one from Tim's computer back to Will. You can do this easily, by selecting the message that arrived in Tim's list, and clicking the Reply button.

Notes:

  1. The Postcard needs a suitable queue manager to act as mailman. The default configuration is the easiest way to get one. If you did not install this when WebSphere MQ was installed, you will be prompted to do it when you start Postcard. You are recommended to take the defaults - it doesn't take long.

  2. Instead of the default configuration you can also start Postcard on any other local queue manager.

  3. If you want to send postcards to another computer, the default configuration must include the option of being joined in the same cluster, or if you are using other queue managers they must either be in the same cluster or you must create a connection explicitly between them.
