Processing IBM MQ messages

IBM® App Connect Enterprise provides a number of nodes for handling messages that are received from or sent to IBM MQ applications.

About this task

If you intend to use IBM App Connect Enterprise to process MQ messages, you must install IBM MQ in addition to installing IBM App Connect Enterprise. 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 App Connect Enterprise, in addition to installing MQ server on the machine that is running your queue manager. IBM MQ is available as a separate installation package, and your IBM App Connect Enterprise license entitles you to install and use IBM MQ with IBM App Connect Enterprise. For more information, see Interaction between IBM App Connect Enterprise and IBM MQ and Installing IBM MQ.

The following nodes are provided for working with IBM MQ messages:
MQInput node
Use an MQInput node if the messages arrive on an IBM 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 an IBM MQ queue, or on the IBM MQ reply-to queue that is specified in the input message MD.
MQGet node
Use an MQGet node to retrieve a message from an IBM 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 IBM MQ reply-to queue that is specified in the input message MD.
MQHeader node
Use the MQHeader nodes to manipulate IBM 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 IBM MQ JMS provider.

The JMSMQTransform node can be used to send messages to existing message flows and to interoperate with IBM MQ JMS and IBM MQ Publish/Subscribe.

MQJMSTransform node
Use the MQJMSTransform node to receive messages that have an IBM 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 IBM MQ JMS and IBM MQ Publish/Subscribe.
