FAST Feed Handler Configuration

FAST Feed Handler configuration dialog 1

Operations Console communicates with the FAST Feed Handler through an intermediary UAF agent. Use this dialog to set the UAF agent listening port and optional UAF agent component name.

Table 1. FAST Feed Handler dialog 1 configuration options
Field Name	Default value	Description
Listen Port	3101	Identifies the UDP Local listening port for incoming messages.
Component Name	None	Identifies this component. This name appears in the component’s panel on the Operations Console Monitor. Naming the component provides an identity that distinguishes this component from other components of the same type. Projects may include several subscribers or publishers. Track items easier by assigning unique component names to them.

FAST Feed Handler configuration dialog 2

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

Table 2. FAST Feed Handler dialog 2 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. Network resources are optimized since the various channel loads are allowed 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 3

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.

Table 3. FAST Feed Handler dialog 3 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. Track Channel Names more easily in teh event that an error is logged by assigning unique names to channels .
Local Interface	None	Identifies the IP address of the network interface to which this channel will be bound. Enhance performance by binding various data channels to separate network interfaces. 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 4

FAST Feed Handler listens for administrative requests from Operations Console and resend requests from subscribers. Use this dialog to set different listening ports and performance options.

Table 4. FAST Feed Handler dialog 4 configuration options
Field name	Default value	Description
Administration Listening Port	3102	Identifies the listening port that the publisher uses to monitor administrative requests (including shutdown, restart, and refresh commands) from Operations Console.
Resend Listening Port	3103	Identifies the port that the publisher uses to resend cached message packets to the subscriber. Publishers maintain a cache of recently sent message packets to ensure that the subscriber processes all message deliveries.
Number of packet buffers	10000	Identifies the number of packet buffers. The publisher holds onto arriving packets of messages until the packets are processed. The number of packet buffers is per data stream. This setting can have a value between 1 and 4 billion, but the machine must have enough memory to hold the number of packets specified. This setting should be adjusted if resend requests from publishers are failing, because the packet no longer exists at the publisher. For the publisher, a value of 10000 will usually provide sufficient packet history to maintain data integrity under moderate loads.

FAST Feed Handler configuration dialog 5

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 theJINI server host name, the installer does not display this dialog.

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

Table 5. FAST Feed Handler dialog 5 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.
