A Configuration Parameters
CME Gateway System Administration Manual 133
Trading Technologies International, Inc.
Parameter Description
FastTemplates For 7.16.0 or higher versions, sets the location
of the FASTTemplates.xml file. The path to the
file can be changed to a customized location
relative to the TT configuration directory
(\config) by configuring this parameter. By
default, this parameter is not present and the
gateway automatically locates the
FASTTemplates.xml file in the \config
directory.
For information on how the CME Gateway uses
the FASTTemplates.xml file, refer to the section
called FIX/FAST Behavior on page 52.
FASTSubject#=Subject/ Configures the type of data (i.e., products) to
which the CME Gateway subscribes. You can
subscribe to any market data that has a
[fastInterface] section in the fast.cfg file.
The value of this parameter must exactly match
the value of a subject parameter in the fast.cfg
file. The CME Gateway uses fast.cfg to
determine how to connect to CME Group to
subscribe to the specified data.
The # in the FASTSubject# parameter starts at
1 for the first subject you include and increases
by 1 for each additional subject parameter you
include in this section. Each # must be unique.
The Price Server limits subscribing to more than
14 FIX-FAST market data channels per CME
Gateway. For recommendations on which
combinations of subject parameters to enable in
order to configure the CME Gateway for
optimal perfomance, refer to the section
called Recommendations for Optimal
Performance on page 58.
Warning: If the CME Gateway
subscribes to more than 14 FIX-FAST
market data channels, the Price Server
immediately logs an error message and
displays as Exchange Feed Down (half
red, half green) in Guardian. If this occurs, you
will need to adjust the number of FASTSubject#
parameters enabled in the [price_session]
section and restart the Price Server.
NetworkInterfaceFeed*=IP Sets the IP Address of the CME Group-facing
NIC. If you use multiple CME Group-facing NICs,
using Feed* you must specify which MDP feed
the TT Gateway routes over the NIC. The Feed*
section of this parameter maps to the same
section in the parameter AddressFeed* in the
fast.cfg file. If you have only one CME Groupfacing
NIC, use NetworkInterface=IP, the TT
Gateway uses this as the default NIC for all MDP
feeds.
For further details and examples, refer to the
section called Configuring Multiple NIC
Setup on page 41.
