T7 production environment: Increase in the number of partitions and change of the Partition ID for some non-DAX instruments

Release date: 15 Dec 2021

087/2021 T7 production environment: Increase in the number of partitions and change of the Partition ID for some non-DAX instruments Xetra Circular 087/21 T7 production environment: Increase in the number of partitions and change of the Partition ID for some non-DAX instruments

1. Introduction

Deutsche Börse is planning to increase the number of partitions available in the T7 production environment (MIC: XETR) from ten to eleven. Following the addition of the new partition (Partition 60), some non-DAX® instruments will be redistributed to the new partition from business day 21 February 2022 onwards.

For the affected products, the existing multicast addresses and ports for the dissemination of the market data via the EMDI, and MDI interfaces will remain unchanged. The multicast addresses for the dissemination of market data via the EOBI interfaces on the other hand will change in most cases. Participants with high-frequency sessions (HF sessions always use the partition-specific gateways) will also be directly affected by these changes. The product reference data will be modified accordingly to reflect the new partition ID.

On Saturday 19 February 2022, Deutsche Börse will offer a connection test between 14:00 CET and 16:00 CET to provide participants the opportunity to test their connectivity on the ETI, RDI, FIX LF, EMDI and EOBI interfaces following the activation of partition 60 and the move of the products. The reference data containing the respective changes will be provided for the connection test.

The circular outlines the most important information relating to the addition of the new partition. 

Start of production: 21 February 2022

2. Required action

Moving products from one partition to another may lead to a scenario where GTC/GTD orders entered and owned by one high-frequency session come to reside on two different partitions. As a high-frequency session login is always partition-specific (via a partition-specific gateway), the respective owning session needs to login to the new partition to manage orders for products which have been moved. To manage orders for products which have not been moved, the owning session needs to login to the old partition.

Participants may require additional high-frequency sessions for the new partition and must therefore ensure that they order them via the Member Section of Deutsche Börse Group. New sessions ordered between Monday and Friday before 17:30 CE(S)T will become active on the next business day.
