Eurex Exchange Readiness Newsflash | Refresher Newsflash: Incident Handling

Dear Eurex Participants,

The average availability over the last 12 months of the Eurex T7 trading system is far above 99.90 per cent. However, we want to support our Trading Participants to be prepared as best as possible for the rarely occurring incident cases, as experienced on 14 April 2020.

Hence, we will start publishing Newsflash messages on a regular basis dealing with the incident handling of different special incident cases or providing more general incident handling information. 

Partition-Specific (PS) Gateway Failure/Secondary Partition-Specific (PS) Gateway starts as leader Partition-Specific (PS) Gateway

1.    Background information

A PS Gateway service might become unavailable for reasons such as hardware failure, network outages or software problems. 

Active sessions on that gateway will be disconnected and all quotes and non-persistent orders of sessions logged in via the failed PS Gateway will be deleted.

The designated standby PS Gateway will be activated and will start accepting session logins. After a timeout period, order maintenance will become available on the now active PS Gateway.

A failure of a Gateway leads to the termination of the TCP connection. The T7 System will recognise the failure of the PS Gateway and will activate the standby PS Gateways. Sessions may subsequently login to the activated PS Gateway. T7 broadcasts a message of the form “XEUR: Partition x: PS Gateway failover triggered, please login to standby PS Gateway".

In case the secondary PS Gateway starts as leader PS Gateway, T7 broadcasts a message of the form “XEUR: Partition x: standby PS Gateway is active gateway".

Broadcast messages are also published on the Production Newsboard on the Eurex website under the following path:

Trading > Production Newsboard 

2.    Best practice

If an active ETI session is disconnected, for any reason, the Trading Participant application should first try to reconnect to the PS Gateway and in case of a failed connection should try the secondary PS Gateway (IP addresses available in the Network Access Guide). The Session Login Response (or reject) will inform about the status of the PS Gateway.

3.    Further information

For further information, please have a look into the T7 Incident Handling Guide (Chapter 3.2), under the following path:

Technology > T7 Trading architecture > System documentation > Release 8.1 (or latest release version) > Production
