Hello I am trying to use batch to request TREP data using ema api.

I request 9000 Rics in batch mode. I am running into this exception. Can you advise please?

Below my config file:

I tried setting the property GuaranteedOutputBuffers to 10000 and then to 100000.

<EmaConfig>


    <ChannelGroup>
        <ChannelList>
            <Channel>
                <Name value="Channel_1" />
                <ChannelType value="ChannelType::RSSL_SOCKET" />
                <GuaranteedOutputBuffers value="100000"/>
		<Host value="xxxxxxx" />
                <Port value="14002" />
            </Channel>
        </ChannelList>
    </ChannelGroup>

    <DefaultConsumer value="cunsumer1"/>
    <ConsumerList>
        <Consumer>
            <!-- Name is mandatory-->
            <Name value="cunsumer1"/>
            <!-- Channel is optional: defaulted to "RSSL_SOCKET+localhost+14002"-->

Hi @badie.saada

There is a payload size limit on a Batch request - please see this related post

What is the maximum number of RICs in an EMA batch request?
