WebSphere MQ link sender
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.
- We 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 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.
