The WebSphere® MQ link receiver receives messages
sent to a messaging engine over a WebSphere MQ
link. The messages are sent from a sender channel on a WebSphere MQ gateway queue manager
or (for WebSphere MQ for z/OS®) queue-sharing
group in a WebSphere MQ network
to a WebSphere MQ link on a messaging engine.
The WebSphere MQ link receiver, which is part
of the WebSphere MQ link, emulates the behavior
of the receiver channel in WebSphere MQ.
- You can define the attributes of the MQ link receiver when you
define the WebSphere MQ link. The foreign bus connection
wizard helps you to do this.
- A number of MQ link sender and MQ link receiver 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 MQ link receiver communicates with a WebSphere MQ sender channel
on the gateway queue manager or queue-sharing group, and converts
messages in WebSphere MQ format
to messages in service integration format.
- If the initial state of the MQ link receiver is set to Started,
the MQ link receiver starts when the WebSphere MQ
link starts, which means it is available when senders connect to it.
When the WebSphere MQ link is set to Stopped,
the MQ link receiver stops.
- An MQ link receiver can
choose to balance inbound messages across partitioned destinations.

- If an MQ link receiver is stopped, the WebSphere MQ
link becomes unavailable and messages are held on the transmission
queue on the WebSphere MQ gateway
queue manager or queue-sharing group in the WebSphere MQ network.
- Define an MQ link receiver only if you want to receive messages
from a WebSphere MQ network.
You do not need an MQ link receiver if you want only to send outgoing
messages.
