If the operation can't be finished, the session's dynamic status won't be changed.

System response

The system reacts differently depending upon whether an initiator session or an acceptor session was started.

...

  • An acceptor session:
    1. Waits for a Logon message
    2. Changes the current dynamic status to "Connecting". The color indicator turns yellow.
    3. Receives the Logon message from the initiator session
    4. Sends the confirming Logon message
    5. Changes the current dynamic status into "Running". The color indicator turns green.

System response

The system response to the stop operation is as follows:

  • If Stop is selected, FIXICC H2 shuts the connection down and the session changes its current dynamic status to "Disconnected". The color indicator turns red.
  • If Stop with logout option is selected, the session sends the Logout message, waits for a response on the logout message, and the session changes the current dynamic status to "Disconnected" upon receiving the response. The color indicator then turns red.
