Configuring WebSphere MQ on z/OS

Learn how you can configure WebSphere® MQ in setting up your vz/OS® environment.

To configure WebSphere MQ on z/OS:

1. Create your queue manager.
   When you create your integration node, you must specify the queue manager to associate with it. For more information, see the -q parameter information in mqsicreatebroker command - z/OS.
2. Your queue manager must have a dead-letter queue. If the queue manager does not have a valid dead-letter queue, you must define one. Check the STGCLASS value is valid by completing the following steps:
   1. Check that this queue exists by using the WebSphere MQ command: +cpf DIS QMGR DEADQ
   2. Check that the queue exists by using the command: +cpf DIS QL(name) STGCLASS
   3. Then, use: +cpf DIS STGCLASS(...)
3. Creating and deleting components on z/OS uses the WebSphere MQ command server.
   1. Ensure that the command server component is running. The component is normally started automatically.
   2. The command server requires a reply-to queue based on SYSTEM.COMMAND.REPLY.MODEL; by default, this model queue is defined as permanent dynamic. However, if you leave the queue defined in this way, each time you run a create or delete component command these reply-to queues remain defined to the queue manager. To avoid these queues persisting, you can set the SYSTEM.COMMAND.REPLY.MODEL queue as temporary dynamic.
4. If you have enabled WebSphere MQ Security, you must define a set of security profiles for the integration node to work. For a list of the security profiles that are required and instructions on how to define them, see WebSphere MQ authorizations.
