If the primary connection fails and the client system connects to the newly promoted primary Drop Copy Gateway, that instance will begin with the next available outbound sequence number to the client (outbound sequence number could be higher due to unprocessed in-flight messages).The client application should connect to the newly promoted primary Drop Copy Gateway.

CME Globex initiates failover by electing the ranking inactive designated backup Drop Copy Gateway to assume the primary role.

If connection to primary host has been dropped, CME allows to connect to backup host: Handler handler2 = new Handler(senderCompId, targetCompId, senderSubId, targetSubId2, senderLocationId) Same SenderCompId and SenderSubId, but different TargetSubID Handler handler1 = new Handler(senderCompId, targetCompId, senderSubId, targetSubId1, senderLocationId)

The following example demonstrates how to how to connect to multiple segments. SenderCompId and SenderSubId will be same for all segments. Note Segment id is specified as session TargetSubID. Please see miltisegment sample from installation package. To create one handler instance for each segment. To connect to multiple segments, there is need Handler instance allows to connect to single segment only. Methods, which accepts accessKeyID and secretKey parameters. To provide secure keys to DropCopy Handler please call one of Handler.logon() Secure Logon procedure was implemented inside DropCopy Handler. If the values do not match, CME Globex rejects the logon.Ĭustomers must create secure key pairs for iLink and Drop Copy Sessions in the CME Customer Center. To calculate the HMAC value to validate against the logon request. When CME Globex receives the logon message, it uses the identical inputs

(HMAC) generated from a combination of the logon FIX tag values.

Message confidentiality and integrity - to credential the logon message, the client system sends a keyed-hash message authentication code.

#Cme dropcopy implementation verification

Customer identity verification - a client system logon request will be signed with security credentials issued and validated by CME Group.

The new logon procedure secures the client system logon with:

Clean-up resources by invoking. method.ĬME Globex implemented secure authentication for iLink and Drop Copy sessions on Convenience Gateway (CGW) and Market Segment Gateway (MSGW).

Process data of the events for which listeners were previously registered.

Note It's highly recommended to read the ' Drop Copy Service' CME AutoCert+ Drop Copy 4.0 pre-certified.High-level Java API allows to build applications rapidly to get drop copy data without much involving into raw protocol specifics.ĬME Drop Copy Handler implementations features include: To the CME Group Drop Copy services using FIX Protocol.
