CME Gateway System Administration Manual 125
Trading Technologies International, Inc.
Configuration Parameters
Overview The CME Gateway uses hostinfo.cfg (located in :\tt\config) to
configure its connection parameters and behavior. If this file is not configured or
used properly, the CME Gateway will not function correctly. You must configure
the hostinfo.cfg file at the time of installation, and again later, if any changes are
made to network setup or trader logon IDs.
The default hostinfo.cfg on CME Gateways includes the following sections that
contain parameters which affect the behavior of the CME Gateway:
• [order_session_#]: The Order Server on the CME Gateway uses this
section to configure an order session with CME Group. Additionally, this
section has two optional parameters to set the deletion of stale orders from
the order book.
• [price_session]: The Price Server on the CME Gateway uses this section to
configure a price session with the CME Group.
Hostinfo.cfg may have lines that begin with the “#” symbol. These lines are
informative and do not configure program behavior.
When editing configuration files (.cfg), each logical set or entry must have its own
line.

Section: [order_session] The Order Server uses this section to configure an order session with CME Group.
For each order session that the Order Server maintains, you must include a
[order_session_#] section. Additional sections configure an Order Server on the
CME Gateway to host multiple CME Group memberships.
You must assign each section a unique name using the # part of the name. For
example, if you have two sections in your hostinfo.cfg, you could simply name
them:
