A20: Aggregate item limit exceeded from RTO

Daniel Zhang

Hi,

I am using EMA API Java to connect to RTO end point ap-northeast-1-aws-3-sm.optimized-pricing-api.refinitiv.net via tcp/14002/rwf protocol. When sending a batch request of more than 2000 rics, we are receiving many status message saying state="Closed / Suspect / Too many items / 'A20: Aggregate item limit exceeded.'" Based on the stream Ids of refresh messages received, the first around 900 rics were successfully returned the refresh message.

Do we have any such limitations in EMA API / RTO end and if so, how we can increase it ?

Regards,

Daniel

Hello @Daniel Zhang

The "A20: Aggregate item limit exceeded." error message means the item open limit for the user has been reached.

The aggregate item limit value is controlled by the ADS aggregateItemLimit configuration parameter, so it generally occurs with the deployed Refinitiv Real-Time Distribution System (aka RTDS/TREP) connection scenario.

However, since you are connecting to the RTO server, I highly recommend you contact the RTO support team to verify the issue on the server-side.

You can contact them via the my.refinitiv.com website.

Thank you wasin. This was sorted out after adding my machine ID's watchlist limit.
