As part of the Express installation, you can choose to configure the Demo Feed Handler. You can identify multicast data channels and identify the JINI host server.
Demo Feed Handler configuration dialog 1
Demo 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.
Demo Feed Handler dialog 1 configuration options
Field name
|
Default value
|
Description
|
Channel Name
|
Demo Channel 1
|
Identifies the data channel that Demo
Feed Handler uses to send messages to a subscriber. Although the
installer assigns Demo 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 in order 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 Demo Feed Handler uses to multicast messages to subscribers.
This value should match the multicast address that the subscribers
use 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
|
3050
|
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 that there is a checkmark
in the
I would like to define another data channel
box
to display a blank data channel dialog.
-
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.
Demo Feed Handler configuration dialog 2
Installing Operations Console also installs a JINI server
that tracks RAP components. This dialog prompts you for the JINI
server host name, which is the same host machine where you install
Operations Console.You must identify the JINI Server Host Name to
register Demo Feed Handler with the JINI Server.

Identifies the host name of the server
where the RAP JINI server resides. This is the machine on
which Operations Console is installed.
