  1. Listening ports can be defined via FIXServer constructors:

    Code Block
    languagejava
    // Create a FIX server, with default configuration from fixengine.properties, which listens to ports 8090, 8091, 8092
FIXServer server = new FIXServer(8090, 8091, 8092);
server.start();
...
    Code Block
    languagejava
    // Create a FIX server, with custom configuration, which listens to ports 8090, 8091, 8092
FIXServer server = new FIXServer(serverConfiguration, 8090, 8091, 8092);
server.start();
...
  2. It's possible to set listening ports for an already existing FIXServer instance but before its start:


    Code Block
    languagejava
    // Create a FIX server, with custom configuration, or that doesn't listen to ports
FIXServer server = new FIXServer();
// Configure server to listen to ports 8090, 8091, 8092
server.setPorts(8090, 8091, 8092);
server.start();
...

  3. There is also a way to open a listening port for an already started server:

    Code Block
    languagejava
    // Create a FIX server, with custom configuration, or that doesn't listen to ports
FIXServer server = new FIXServer();
server.start()
...
// Open port 8090 to listen
server.openPort(8090);

    The FIXServer.openPort() method can be used with the second parameter, which defines if the port can be automatically closed when deregistered the last acceptor for such port (see Managing listening ports via configuration):

    Code Block
    languagejava
    // Create a FIX server, with custom configuration, or that doesn't listen to ports
FIXServer server = new FIXServer();
server.start()
...
// Open port 8090 to listen 
server.openPort(8090, true); // autoclose = true

    FIXServer.openPort() method can be used with the second parameter, which defines is the port can be automatically closed when deregistered the last acceptor for such port:

...

  1. FIXServe.getPorts() return a list of actually configured ports. It also returns a list of ports, defined with constructor or with setPorts() method, before the start:

    Code Block
    languagejava
    FIXServer server = new FIXServer();
server.getPorts(); // returns {}

server.setPorts(8090, 8091, 8092);
server.getPorts(); // returns {8090, 8091, 8092}

server.start;
server.getPorts(); // returns {8090, 8091, 8092}

  2. FIXServe.getOpenPorts() return a list of opened ports - only those ones with can accept incoming connections:

    Code Block
    languagejava
    FIXServer server = new FIXServer();
server.setPorts(8090, 8091, 8092);
server.getOpenPorts(); // returns {}

server.start;
server.getOpenPorts(); // returns {8090, 8091, 8092}

Close open ports

Closure Explicit closure of the port explicitly is performed in the following way:

...

FIX Antenna Java engine can automatically manage listening ports for a server during registration/deregistration acceptor sessions. It works only if the port property is defined for the acceptor session. Additionally, such an acceptor could be connected only on the defined port:
