FAST Feed Handler Express Configuration

As part of the Express installation, you can choose to configure the FAST Feed Handler. You can provide FAST feed parameters, identify data channels to be used by the Feed Handler, and enter the JINI server host name.

FAST Feed I Handler configuration dialog 1

FAST Feed Handler listens for FAST messages sent by a FAST feed. This dialog prompts you for the FAST feed parameters.

FAST Feed Handler dialog 1 configuration options
Field Name	Default value	Description
Listen Host IP Address	None	Identifies the IP address for a network interface to which the incoming feed's UDP channel will be bound. This allows the optimization of network resources by allowing various channel loads to be spread out among multiple physical network adapters.
Listen Port	3170	Identifies the UDP Local listening port for incoming messages.
Multicast Host IP Address	224.0.255.0	Identifies the class D (multicast) IP address on which this data channel will operate. A publisher can multicast messages to a subscriber on multiple channels, and the combination of the Broadcast IP Address and Broadcast Port must be unique for each channel. All multicast IP addresses must range from `224.0.2.0` through `224.0.255.0`.

FAST Feed Handler configuration dialog 2

FAST Feed Handler multicasts messages to subscribers over one or more data channels. Four channels are recommended for a system that handles 300,000 messages per second. Use this dialog to identify the data channels.

FAST Feed Handler dialog 2 configuration options
Field name	Default value	Description
Channel Name	FAST Channel 1	Identifies the data channel that FAST Feed Handler uses to send messages to a subscriber. Although the installer assigns FAST Channel 1 to the first data channel by default, you can use any value as the channel name. You must supply a Channel Name to any subsequent data channels you define. Assigning unique names to channels can help you track each one more easily in the event that an error is logged.
Local Interface	None	Identifies the IP address of the network interface to which this channel will be bound. This allows you to bind various data channels to separate network interfaces to enhance performance. If you plan to install all publishers and subscribers on the same server, you must configure the Local Interface to use the loopback interface (127.0.0.1). If you install publishers and subscribers on different servers, use the local machine address of the secondary Ethernet network card installed by the system administrator.
Broadcast IP Address	224.0.2.0	Identifies the Class D multicast IP address that FAST Feed Handler uses to multicast messages to subscribers. This value should match the multicast address that the subscriber uses to receive messages. Although the installer assigns 224.0.2.0 as a default multicast IP address to all Broadcast IP address fields, your Network Administrator can choose an alternate multicast address. All multicast IP addresses must range from `224.0.2.0` through `224.0.255.0`.
Broadcast Port	3150	Identifies the local port on which this data channel will operate. Publishers can multicast messages to a subscriber on multiple data channels. Data channels can share the same local interface and Broadcast IP Address values, but the Broadcast Port must be unique for each data channel.

Note:

After you define the first channel, do one of the following:

Click Next, making sure there is a checkmark in the I would like to define another data channel box to define another data channel.
Remove the checkmark in the I would like to define another data channel box, and click Next to display the next set of configuration options.

FAST Feed Handler configuration dialog 3

Installing Operations Console also installs a JINI server that tracks RAP components. This dialog only appears if you install components separately. If you install multiple components at the same time, and previously identified the JINI server host name, the installer does not display this dialog.

If this dialog appears, you must identify the JINI server host name to register FAST Feed Handler with the JINI Server. The JINI server host name is the same host machine where you install Operations Console.

FAST Feed Handler dialog 3 configuration options
Field name	Description
JINI Server Host Name	Identifies the host name of the server where the RAP JINI server resides. This is the machine on which Operations Console is installed.
