Gateway Recovery:
Hardware
Example Scenario 1 -
Single CME Gateway
6 Disaster Recovery
Warning: Starting the Order Server in this manner can result in the loss of fill
information.
After you replace any failed hardware and restart the CME Gateway, recovery
processes are identical to those listed above for Gateway Software Recovery.
However, if the hard drive is replaced, traders are unable to access any of their
order or fill information as the relevant log and table files are permanently lost.
Traders must call the exchange and cancel their working orders. If the trader is on
a position and must close it, he must do so through a broker.
Quick Financial Services (QFS) has one CME Gateway. During trading hours, their
gateway experiences a drive head crash, and immediately, all traders lose their
connection to the exchange. The exchange displays red in Guardian, prices stop
updating, and traders stop receiving fills. Even if they have X_TRADER® open,
traders lose the ability to trade on CME Group. Before closing out of their
workspaces, traders document their positions. Traders, who must cancel orders,
call the exchange.
QFS installs and starts up another CME Gateway that same day. After startup, Jim
(a trader) logs into the new CME Gateway. Jim opens up his workspaces and
grids. He then begins trading at current market prices.
