RAPCache Subscriber Express Configuration

RAPCache subscriber configuration dialog 1

RAPCache subscriber listens to one or more data channels for data sent by publishers. Use this dialog to identify each channel that you want RAPCache subscriber to monitor.

RAPCache subscriber dialog 1 configuration options
Field name	Description
Channel Name	Identifies a specific data channel that a particular publisher uses to send messages to RAPCache subscriber using multicast. The channel name depends on the data channel you want RAPCache subscriber to monitor. For example, if you want to RAPCache subscriber to monitor FAST feed handler, and kept all the defaults when you defined the FAST feed data channels, use FAST channel 1 as the first channel name. Subsequent channel names match those of other data channel names.
Publisher Name	Identifies the publisher that sends messages to this subscriber, in the event that an error is logged.
Local Interface	Identifies the IP address of the network interface that the publisher uses to send multicast messages to RAPCache subscriber. This value must match the local interface value that the publisher uses to send messages via multicast. For example, if you want RAPCache subscriber to monitor a particular FAST feed handler data channel, the local interface value you use here must match the local interface value for the data channel you defined for FAST feed handler.
Broadcast IP Address	Identifies the Class D multicast IP address that the publisher uses to send multicast messages to RAPCache subscriber. This value must match the multicast address that the publisher uses to send multicast messages to RAPCache subscriber. For example, if you want RAPCache subscriber to monitor a FAST feed handler data channel that sends multicast messages on 224.0.2.0, use that address for this field. All multicast IP addresses must range from 224.0.2.0 – 224.0.255.0.
Broadcast Port	Identifies the port from which the publisher sends multicasts messages to RAPCache subscriber. Publishers can send multicast messages to a RAPCache subscriber on multiple data channels that share the same local interface and broadcast IP address, but the broadcast port must be unique to each data channel.

Note:

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

Click Next, making sure that "I would like to define another data channel" is selected.
Unselect "I would like to define another data channel", and click Next to display the next set of configuration options.

Unselect "I would like to define another publisher", and click Next to display the next set of configuration options.

RAPCache subscriber configuration dialog 3

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

If this dialog appears, you must identify the JINI server host name to register the RAPCache subscriber with the JINI server.
