BOEv3 Convenience (BOEv3c)
Order Handler Redundancy in Primary Data Center
There are no explicit separate BOEv3c address, port or credentials. Cboe will activate a replacement order handler when necessary using the same address, port and credentials. Sequences on an activated replacement will match primary, less anything very recent lost during failover. Please note that there is no way to communicate with dormant backup port before it is activated.
Disaster Recovery Data Center
Cboe configures an order handler session in DR data center (Chicago for US) for each primary site order handler session. Members are able to connect, login, and heartbeat to the DR session at any time during trading operations. Unless the DR data center has been activated all application-level messages (orders, quotes) will be rejected.
Login credentials are the same as the primary site.
The DR sessions have independent sequence numbering, and will not support the replay of messages from the primary data center.
