Configuring Miscellaneous System Behavior Documentation

Configuring TTM


You can configure TTM’s service numbers and daemon setup (such as the port that the daemon uses, its NIC card interface, and its multicast address).

TTM Daemon Setup


Because the AConfig Utility does not also update the ttmd.cfg file (which TTM also reads from), do not use the AConfig Utility to change Daemon Setup values in aconfig_local.xml. Instead, use the Guardian GUI as described in the TT Trading Systems – Network Administration Manual. The Guardian GUI updates both the aconfig_local.xml and ttmd.cfg files.

There are two areas in aconfig_local.xml that contain TTM Daemon setup parameters:

  • Local: Configures the local daemon’s communication parameters.
  • Remote: Stores the remote daemon’s communication parameters. This section does not configure the remote daemon’s behavior. It only sets the local daemon’s expectations of the remote daemon’s configuration.
TTM Daemon Setup Parameters

Locations: For local daemon setup: AConfigCoreMessagingProximity-SpecificLocal For remote daemon setup: AConfigCoreMessagingProximity-SpecificRemote




Function: Sets the IP address to which the TTM daemon connects.

In the Local section, setting of default sets TTM to use the primary IP address.

Default setting: default


Function: Sets the TCP port number on which the TTM daemon communicates.

Default setting: 10200


Function: Sets the network interface (i.e., NIC card) on which the TTM Daemon sends and receives multicast information. A setting of default sets the TTM daemon to use the primary NIC card.

Default setting: default


Function: Sets the multicast group on which the TTM daemon sends its multicast.

Deprecated in TTM 1.5.

Default setting:

Service Usage

The following table lists parameters that set the service numbers TT applications use when sending data to TTM. For more detailed information on Service numbers and how TT applications use them, refer to the TT Trading Systems – Network Administration Manual.

Both production and simulation modes have their own service settings.


TT recommends that you do not change any of the following default values. However, if you do change these values, all machines that communicate with one another must have the same sets of values.

TTM Service Number Assignments

Locations: For Production data: AConfigCoreMessagingServiceProduction For Simulation data: AConfigCoreMessagingServiceSimulation




Function: Sets the TTM service on which TT applications send orders and non-price data.Default setting: For Production: 8900; For Simulation: 8910


Function: Sets the service on which TT applications send price data.Default setting: For Production: 8901; For Simulation: 8911


Function: Sets the service on which TT applications send order data.Default setting: For Production: 8902; For Simulation: 8912


Function: Sets the service on which TT applications send heartbeats.Default setting: For Production: 8900; For Simulation: 8910


Do not change the default value of these parameters unless instructed to do so by TT support.
