About this task
If you intend to use IBM Integration Bus to process MQ messages, you
must install WebSphere MQ in addition to installing IBM Integration Bus. On distributed systems, if you want to
connect to a remote queue manager to process MQ messages, you must install either an
MQ Client or MQ Server on the same machine as IBM Integration Bus, in addition to installing MQ server on the machine that is running your queue
manager. On z/OS®, you use only local connections to
queue managers. WebSphere MQ is available as a separate
installation package, and your IBM Integration Bus license
entitles you to install and use WebSphere MQ with IBM Integration Bus. For more information, see Enhanced flexibility in interactions with WebSphere MQ and Installing WebSphere MQ.
The following nodes are provided for working with
WebSphere MQ messages:
- MQInput node
- Use an MQInput node
if the messages arrive at the integration node on a WebSphere MQ queue, and the node is to be
at the start of a message flow.
- MQOutput node
- Use an MQOutput node
if the target application expects to receive messages on a WebSphere MQ queue, or on the WebSphere MQ reply-to queue that is specified
in the input message MD.
- MQGet node
- Use an MQGet node to
retrieve a message from a WebSphere MQ queue,
if you want to get the message later in the message flow.
- MQReply node
- Use an MQReply node
if the target application expects to receive messages on the WebSphere MQ reply-to queue that is specified
in the input message MD.
- MQHeader node
- Use the MQHeader nodes
to manipulate WebSphere MQ transport
headers and their properties without writing compute nodes. Use the MQHeader node to add, modify,
or delete Message Descriptor (MD) and Dead Letter Header (DLH) headers.
- JMSMQTransform node
- Use the JMSMQTransform node
to transform a message with a JMS message tree into a message that
has a tree structure that is compatible with the format of messages
that are produced by the WebSphere MQ JMS
provider.
The JMSMQTransform node
can be used to send messages to existing message flows and to interoperate
with WebSphere MQ JMS and WebSphere MQ Publish/Subscribe.
- MQJMSTransform node
- Use the MQJMSTransform node
to receive messages that have a WebSphere MQ JMS
provider message tree format, and transform them into a format that
is compatible with messages that are to be sent to JMS destinations.
You
can use the MQJMSTransform node
to send messages to existing message flows and to interoperate with WebSphere MQ JMS and WebSphere MQ Publish/Subscribe.
