This topic describes the WebSphere MQ link receiver, which receives
messages sent from a queue manager in a WebSphere MQ network to a WebSphere MQ link on
a messaging engine in a service integration bus.
The WebSphere MQ link receiver (MQLinkReceiver) receives messages sent
to a messaging engine with a WebSphere MQ link,
from a sender channel on a WebSphere MQ gateway queue manager. The WebSphere
MQ link receiver, part of the WebSphere MQ link,
emulates the behavior of a WebSphere MQ receiver channel in WebSphere MQ.
- You can define the attributes of the MQLinkReceiver when you define the WebSphere MQ link.
- A number of MQLinkSender and MQLinkReceiver attributes, which are grouped
together on the same administrative console panel, are common, that is, the
value you enter is used for both the sending and receiving ends of the link.
- The MQLinkReceiver communicates with a WebSphere MQ sender channel on
the gateway queue manager, and converts messages in WebSphere MQ format to
messages in service integration format.
- If the MQLinkReceiver's initial state is set to start, it will start when
the WebSphere MQ link starts, which means
it is available when senders connect to it. When the WebSphere MQ link is
set to stop, the MQLinkReceiver stops. For details of the states of the WebSphere
MQ link receiver, see States of the WebSphere MQ link and its channels.
- If the MQLinkReceiver cannot send an inbound message to a target destination,
the message is sent to an exception destination. To read about exception destinations
see Exception destinations.
- If an MQLinkReceiver is stopped, the WebSphere MQ link becomes
unavailable and messages are held on the transmission queue on the WebSphere
MQ gateway queue manager in the WebSphere MQ network.
- Define a receiver channel only if you wish to receive messages from a
WebSphere MQ network; that is, not if you wish only to send outgoing
messages.
