The WebSphere® MQ link sender converts messages
to WebSphere MQ format messages,
and then sends them to a receiver channel on the WebSphere MQ gateway queue manager
or (for WebSphere MQ for z/OS®) queue-sharing
group.
The WebSphere MQ link sender, which is part
of the WebSphere MQ link, emulates the behavior
of the sender channel in WebSphere MQ.
- You can define the attributes of the MQ link sender 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.
- If the initial state of the MQ link sender is set to Started,
the MQ link sender starts when the WebSphere MQ
link starts. When the WebSphere MQ link is set to Stopped, the MQ link sender stops.
- If an MQ link sender is stopped, the WebSphere MQ
link becomes unavailable and messages are held in the service integration
bus until the MQ link sender is started again.
- If the MQ link sender encounters a long reply-to destination name
(that is, too long a name for WebSphere MQ to handle), it
sends the message to an exception destination.
- Define an MQ link sender only if you want to send messages to
a WebSphere MQ network.
You do not need an MQ link sender if you want only to receive incoming
messages.
On the WebSphere MQ link sender channel, there
is a field called Transport chain. This field
can take a value of OutboundBasicMQLink, which communicates
with an unsecured channel, or OutboundSecureMQLink,
which communicates with a secure SSL channel. The unsecured listener
listens for inbound requests on port 5558 and the secure listener
listens for inbound requests on port 5578.
