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 multicast messages to RAPCache Subscriber. The Channel Name depends on the data channel you want RAPCache Subscriber to monitor. If, for example, you want to RAPCache Subscriber to monitor FAST Feed Handler, and kept all the defaults when you defined the FAST Feed data channels, you would use FAST Channel 1 as the first Channel Name. Subsequent channel names would match those of other data channel names.
Publisher Name	Identifies the publisher that sends messages to this subscriber. The Publisher Name can be any value. It is used to identify the publisher in the event that an error is logged.
Local Interface	Identifies the IP address of the network interface that the publisher uses to multicast messages to RAPCache Subscriber. This value must match the local interface value that the publisher uses to multicast messages. If you want RAPCache Subscriber to monitor a particular FAST Feed Handler data channel, for example, 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 multicast messages to RAPCache Subscriber. This value must match the multicast address that the publisher uses to multicast messages to RAPCache Subscriber. If you want RAPCache Subscriber to monitor a FAST Feed Handler data channel that multicasts messages on 224.0.2.0, for example, you would use that address for this field. All multicast IP addresses must range from `224.0.2.0` through `224.0.255.0`.
Broadcast Port	Identifies the port from which the publisher multicasts messages to RAPCache Subscriber. Publishers can 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 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.

RAPCache Subscriber configuration dialog 2

RAPCache Subscriber communicates with one or more publishers. Use this dialog to identify the publisher(s) you want RAPCache Subscriber to monitor.

RAPCache Subscriber dialog 2 configuration options
Field name	Description
Publisher Name	Identifies the publisher that publishes to this subscriber. It is used to identify the publisher in the event that an error is logged.
IP Address	Identifies the IP address of the machine on which the publisher resides. This is used to connect to the publisher to request resends of packets.
Resend Listener Port	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.

Note:

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

Click Next, making sure there is a checkmark in the I would like to define another publisher box to define another publisher.
Remove the checkmark in the I would like to define another publisher box, 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 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 the RAPCache Subscriber with the JINI Server. The JINI server host name is the same host machine where you install Operations Console.

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.
