Configure an AMQP client for high availability
We can configure MQ Light or AMQP 1.0 applications to connect to the active instance of an IBM MQ multi-instance queue manager and fail over to the standby instance of the multi-instance queue manager in a high availability (HA) pair. To do this, you configure the AMQP application with two IP addresses and port pairs.
We can configure the MQ Light API with a custom function, which is called if the client loses its connection to the server. The function can connect to an alternative IP address, for example a standby IBM MQ queue manager or to the original IP address. For other AMQP clients, if the client supports configuration of multiple connection endpoints, configure the application with two host-port pairs and use the reconnect features provided by the AMQP library to switch to the standby queue manager.
