IBM MQ link receiver
The IBM MQ link receiver receives messages sent to a messaging engine over a IBM MQ link. The messages are sent from a sender channel on a IBM MQ gateway queue manager or (for WebSphere® MQ for z/OS®) queue-sharing group in a IBM MQ network to a IBM MQ link on a messaging engine.
The IBM MQ link receiver, which is part of the IBM MQ link, emulates the behavior of the receiver channel in IBM MQ.
- You can define the attributes of the MQ link receiver when you define the IBM 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 IBM MQ sender channel on the gateway queue manager or queue-sharing group, and converts messages in IBM 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 IBM MQ link starts, which means it is available when senders connect to it. When the IBM MQ link is set to Stopped, the MQ link receiver stops.
- An MQ link receiver can choose to balance inbound messages across partitioned destinations. To read about workload balancing, see Workload sharing with queue destinations
- If an MQ link receiver is stopped, the IBM MQ link becomes unavailable and messages are held on the transmission queue on the IBM MQ gateway queue manager or queue-sharing group in the IBM MQ network.
- Define an MQ link receiver only if you want to receive messages from a IBM MQ network. You do not need an MQ link receiver if you want only to send outgoing messages.
