This topic describes the Drop Copy impacts for a DR event on EBS Market and eFix, for both MSGW and CGW source sessions.

After notification that a DR event has occurred, impacted customers will be required to connect to the DR environment for the Drop Copy service and real-time copies of their execution reports. Since the trading platform moves to a regionally diverse datacenter, network latency may be affected.

Drop Copy DR Impacts

Please review the full DR Process overview, then see below for Drop Copy specifics.

State 1: Normal Production Processing (Pre-DR)

EBS Market on and eFix Drop Copy are in a normal production state.

State 2: DR Event

In the affected Production environment, Drop Copy gateways will be unavailable. CME Group will eliminate all open orders but Drop Copy messages will not be sent to customers; customers must clear their systems of any working orders.

State 3: Connect and Trade in the DR Environment

Drop Copy MSGW sessions for EBS Market and eFix Matching are replicated in both environments. An MSGW client can consume Drop Copy messages in the DR environment using their production session, with the DR IPs and ports.

• The Drop Copy MSGW session must be redirected to the EBS Market on CME Globex DR environment by reconnecting using your sessions' DR IP and port.

• The Drop Copy MSGW IDs in DR may be different than those used in Production. If different, customers will receive a Logout message (tag 35=5) stating the new Drop Copy MSGW ID. Customers can then send a new Logon message with the Drop Copy DR MSGW ID. 

Drop Copy CGW sessions are only created on a single gateway. A Drop Copy CGW client must use a session created in the DR data center.

Please see the Drop Copy scenarios below for examples.

Pre-DR event message recovery is not available.

State 4: Return to Production

For the return to Production, Drop Copy MSGW clients must revert their session configurations to their Production IPs and ports. Drop Copy CGW clients must re-establish their sessions in the Production data center.
