atsStatus-A23: Service has gone down. Will recall when service becomes available.

Hi,

We are using ETA Value Added API to fetch realtime data from TREP, but for our customer, everyday at 07:00 AM in morning, another team in the bank is restarting their system, and it caused error message "-A23: Service has gone down. Will recall when service becomes available".

What is the way to handle this through ETA? Will ETA take care of it? or we need to resubscribe to all the tickers using that service?

Please sugges, what is recommended way to handle this service.

Thanks

Thanks for reaching out to us.

You need to check the stream state of the subscribed item.

If the stream state is still Open, it means that the API or the infrastructure will perform a recovery on behalf of the application.

StatusMsg
    streamId="5"
    domain="MarketPrice Domain"
    state="Open / Suspect / None / 'F9: Service has gone down. Will recall when service becomes available.'"
    name="IBM.N"
    serviceId="5001"
    serviceName="ELEKTRON_DD"
StatusMsgEnd

However, if the stream state is Closed or Closed_Recover, the application needs to resubscribe to the item.

I hope that this information is of help.

Hi @Jirapongse,

We're seeing this issue as well, and it also happens when other applications on our network begin receiving elevated traffic (for us, our connection to the RTSDK for which we receive European market data suffers when the US markets open).

Do you know why this might be happening? Our application does recover, but it also loses data because of this. How can we configure our application to not be as sensitive to the traffic conditions of the network, if that's what's happening?

This message is sent from the infrastructure (RTDS) to indicate that the service is down and RTDS will perform item recovery. If the application retrieves this message, you need to contact the infrastructure team (RTDS support team) to verify what the problem is.
