Use multiple hosts with EMA Java

Parik

Hello,

We are able to successfully connect and retrieve data using EMA java library,

EmaFactory.createOmmConsumer(EmaFactory.createOmmConsumerConfig().host("host_1:14002").username("user123"));

How do we specify multiple hosts for failback reasons : host_1, host_2, etc.

Can it be done using the libraries or there is any other alternative method?

Thanks

Thank you for reaching out to us.

You need to use the EMA Configurations for configuring failover.

EMA provides the ChannelSet configuration for failover.

		<Consumer>
			<Name value="Consumer_2"/>
			<!-- ChannelSet specifies an ordered list of Channels to which OmmConsumer will attempt to -->
			<!-- connect, one at a time, if the previous one fails to connect -->
			<ChannelSet value="Channel_1, Channel_2"/>
			<Dictionary value="Dictionary_2"/>
			<XmlTraceToStdout value="0"/>
		</Consumer>
