RAPStore Subscriber Express Configuration

As part of the Express installation, you can choose to configure RAPStore Subscriber. You can choose where to store temporary market data files, assign data channels and publishers, and identify the JINI server host name.

RAPStore Subscriber configuration dialog 1

The RAPStore Subscriber temporarily writes market data messages to files. The location of these directories should match the values on your worksheet. These directories are created for you during the install.

Field name

Description

Primary file location

Identifies the directory where the subscriber temporarily writes market data messages before it loads the database.

Overflow file location

Identifies the directory where the subscriber stores temporary market data message files when the primary directory is full.

RAPStore Subscriber configuration dialog 2

RAPStore Subscriber listens on one or more data channels for messages sent by publishers. Use this dialog to identify the data channels you want RAPStore Subscriber to monitor.

Field name

Description

Channel Name

Identifies a specific data channel that a particular publisher uses to multicast messages to RAPStore Subscriber.

The Channel Name depends on the data channel you want RAPStore Subscriber to monitor. If, for example, you want to RAPStore 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 RAPStore Subscriber. This value must match the local interface value that the publisher uses to multicast messages.

If you want RAPStore 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 RAPStore Subscriber. This value must match the multicast address that the publisher uses to multicast messages to RAPStore 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 RAPStore Subscriber.

Publishers can multicast messages to a RAPStore 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.

RAPStore Subscriber configuration dialog 3

The RAPStore Subscriber communicates with one or more publishers. Use this dialog to identify the publishers you want the RAPStore Subscriber to monitor.

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.

RAPStore Subscriber configuration dialog 4

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 RAPStore 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.
