FIX Session Configuration

FIX Session attributes can be divided into three groups:

• Static configuration
• Dynamic state
• Dynamic attributes

To create a new Session configuration, define the static attributes such as:

• Identification parameters
• Specific parameters of the Initiator and Acceptor Sessions
• Others

The parameters of static configuration define the initial parameters for the dynamic parameters. The static configuration can be changed when the current FIX Session is not connected. The parameters of the static configuration can be modified at any time. If the Session is connected, the changes are stored in the database and only the latest changes are applied when the Session becomes disconnected.

A dynamic state exists only when the Session is connected. FIXICC H2 handles the events which are happened during the endpoint's life cycle. These events come from the FIXEdge Server. For the dynamic state, the sequence of events is important for tracking.

Dynamic attributes also exist only when the Session is connected. FIXICC H2 checks the state of these attributes in a configured time interval. The set of metrics depends on the type of FIXEdge Server. For the dynamic attributes, the snapshot at the moment is important.

Static FIX Session Configuration

1. Select a Server to add a new Session configuration to.
   
   Figure. Selecting the Server from the list.
   
   
2. Go from the Servers page to the Server Sessions page by:
   • Clicking FIX in the View drop-down menu on the Servers page (item 1).
   • Clicking the Server Name in the navigation menu and FIX under the Server Name (items 2 and 3).
   • Double-clicking the selected Server configuration.
3. Then FIXICC H2 opens the page with the list of sessions configured for the selected Server.
   
   Figure. The Server Sessions list.

Adding a New FIX Session Configuration from Scratch

To add a new Session from scratch:

1. Press Add.
   
   Figure. Add a Session from scratch.
   
   
2. Choose the new session role from the Add drop-down menu:
   • The Initiator is responsible for establishing the connection (TCP/IP) and sending the first Logon message to the Acceptor. There is a set of parameters for Initiator Sessions.
   • The Acceptor performs authentication and replies with the confirming Logon message to the Initiator as a declaration that the FIX Session has been established. In case of a connection failure, the Acceptor waits until the Initiator initiates reconnection. There is a set of parameters for Acceptor Sessions.

You can also create a new session configuration by:

1. Clicking Create Acceptor Session or Create Initiator Session in the context menu.
2. When you select a new session role, FIXICC H2 opens the New Session page.

Create an Acceptor Session

To create a new Acceptor Session:

1. Select Acceptor from either:
   • The Add drop-down button
   • The context menu
     Figure. The Add Acceptor Session option.
     
     
2. FIXICC H2 opens the New session for a new Acceptor Session.
   
   Figure. Acceptor Session parameters.

The Acceptor Session allows setting the Reset Threshold parameter.

Create an Initiator Session

To create a new Initiator Session:

1. Select Initiator from either:
   • The Add drop-down button
   • The context menu
     
     Figure. Add an Initiator Session.
     
     
2. FIXICC H2 opens the New Session page for a new Initiator Session.

The Initiator Session has a specific, mandatory set of parameters to establish a connection:

• Host - Defines the network IP address of the computer to which the connection is established
• Port - Defines the port network number on the computer to which the connection is established
• HeartbeatInterval - Defines the heartbeat interval (seconds) – a time interval between Heartbeat messages. The recommended value is 10 seconds for dedicated connections or private networks. Trading connections via the Internet requires calibration. '0' means that no Heartbeat messages will be sent.

You can see the parameters in the figure below.

Figure. Initiator Session parameters.

Complete adding a new Session configuration

After you've defined the mandatory connection parameters (Host, Heartbeat Interval, and Port), define the mandatory identification parameters that are highlighted in red in the figure above:

• Name - unique session identifier.
• SenderCompID - the key parameter for purposes of session identification.  Sets the value of the SenderCompID (49) tag in outgoing FIX messages.
• TargetCompID - the key parameter for purposes of session identification. Sets the value of the TargetCompID (56) tag in outgoing FIX messages.
• FIX Version - identifies the session-level FIX protocol version of a message. Sets the value of the BeginString (8) tag in outgoing FIX messages.
• AppVersion - identifies the application-level FIX protocol version of a message. Sets the value of the ApplVerID (1128) tag in outgoing FIX messages. Required if FIX Version is set to FIXT.1.1.

You can find the full list of session parameters and descriptions on the FIX session configuration for FIXEdge Java page.

After specifying all the details, you have the following options:

• Save the new session configuration by clicking OK.

• If all mandatory parameters are specified and the Name, SenderCompID, and TargetCompID values are unique, then a new Initiator Session is added to the selected Server and FIXICC H2 displays the sessions table including the new Session configuration.

  If the Session Name is not unique, FIXICC H2 displays the error form with the message 'Session <session-name> already exists'.
  

  If the session SenderCompID and TargetCompID are not unique, FIXICC H2 displays the error form with the message 'Session with <SenderCompID> and <TargetCompID> already exists'.

Figure. The default Scheduler section.

You can also configure the sequence numbers of a new Session to reset on start by checking the Reset sequence numbers on start checkbox or while editing a Session on the Modify Session page.

Figure. The Scheduler section.

By default, the Session starts/stops with the server option (item 1) is selected and the Session starts and stops with the Server.

When the Session starts/stops according to the schedule option (item 2) is selected, you have the ability to:

• Select a schedule name from the drop-down list by clicking the symbol  (item 3). When you click the schedule name, the Schedule Name, Start Time, Terminate Time, and Time Zone fields are filled with the schedule parameters.

You can also use the Extended Filter for searching Server information.

When you specify the custom schedule for the current session, the View Sessions button is enabled and you can open the Schedule Details page in a new tab by clicking it.

To finish the binding, click OK.

FIXICC H2 binds the current Session with the selected work mode:

• If the Session starts/stops with the server option is selected.
• If the Session starts/stops according to the schedule option is selected and Schedule Name is specified.

If the binding operation failed, an error form and the following notification are shown:

Figure. The binding error form.

Dynamic FIX Session Configuration

Server Sessions

You can monitor the dynamic state of the configured Sessions for a given Server.

Figure. The Servers page.

Go from the Servers page to the Server you choose by using one of the following options:

• Click FIX in the View drop-down menu on the top panel (item 1).
• Click a Server name in the left-side menu > FIX (items 2 and 3).
• Double-click the selected Server configuration.

Now you can see the session monitoring layout.

Figure. The Server Sessions page.

The first column of the table contains the Session status indicator. This parameter shows the dynamic status of each Session configured for the selected Server.

You can easily detect the session status according to the following list:

You can also see the Status column so you can filter the displaying list of the Sessions by dynamic status.

You can monitor the changing of the Session metrics and Session state just by staying at the layout.

The dynamic Session parameters are changed as a response to the Session events during the connection.

The frequency with which the metrics values are updated can be configured. The default value is 1 second.

Filtering

You have the ability to filter the sessions list by using the Default Filter.

You can filter sessions by Status, Name, SenderCompID, TargetCompID, or a combination of them.

You can also use the Extended Filter for searching Server information.

Session Dynamic State

To see the dynamic state and metrics of the selected Session, click on the selected Session on the Server Sessions page in the sessions table in the Table view layout part.

FIXICC H2 displays the Session Dynamic State page in the Object info layout part.

You can also open the Session Dynamic State page in a new tab:
