WebSphere MQ link receiver
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.
- We 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 to receive messages from a
WebSphere MQ network.
You do not need an MQ link receiver if you want only to send outgoing messages.
