FIX Antenna reads the configuration parameters by default from the engine.properties file during initialization.
The user can also assign another name for the configuration file, such as the Engine::FixEngine::init(const std::string& aPropertiesFileName = "") call parameter.
For example:
Engine::FixEngine::init("FE.properties") |

If the real value is not equal to the expected one, then the connections are disconnected without sending a message and the error condition is generated in the log output.
Default 0.0.0.0 - accepts all connections from IP addresses on every network interface.
The license file path.
This property is the path of the directory in which the logs for all incoming (if LogIncomingMessages is set to "true") and outgoing FIX messages are stored.
It is possible to specify a path related to the EngineRoot directory. For example, if LogDirectory is set to "logs", then the real path is /logs. The specified directory must exist.
Optional. Engine's local IP address to send messages from.

An option not to reset sequence numbers after Logout.
Valid values:
If set to true, sequence numbers are not reset after Logout. Logout sender should initiate session recovery by sending Logon message with SeqNum = <last outgoing="" seqnum>=""> + 1; expecting reply Logon with SeqNum = <last incoming="" seqnum>=""> + 1. If a gap is detected, standard message recovery or gap filling process takes place.
If set to false, sequence numbers are reset after Logout.
This parameter specifies the delta (increment) to the Heartbeat interval between a TestRequest message being sent by FIX Engine and a Response Heartbeat being received.
The session attains a "telecommunication failed state" if no Response Heartbeat message is received after the normal Heartbeat interval plus delta. For example, if no message (application or session level) is received during the Heartbeat interval, the engine sends the TestRequest message. If the required Response Heartbeat message is not received during Heartbeat interval plus Delta, then the session moves to the "Telecommunication link failed" state. This parameter is specified in (Heartbeat Interval/100). The recommended value is 20%.
This parameter allows to resolve sequence gap problem automatically.
When the mode is ON, the session uses the 141(ResetSeqNumFlag) tag in sending/confirming Logon message to reset SeqNum at the initiator or at the acceptor. Valid values:
Specifies how much same ResendRequests received before Application::onResendRequestLoop is called.
This option is disabled if value is less than 2.
This parameter defines the list of additional (custom) protocols which require registering of the corresponding parsers.
When FIX Antenna is started, all dictionaries from DictionariesFilesList are loaded. If dictionaries are standard, predefined standard parsers (like FIX40; FIX41; FIX42; FIX43; FIX44; FIXT11) are created basing on them. If any dictionary from DictionariesFilesList is custom, parser is not automatically created and therefore such parsers should be listed in the AdditionalParsersList parameter.
Format of the value: [UNIQUE_PARSER_NAME@][FIXT_PROTOCOL1:]APP_PROTOCOL1[,APP_PROTOCOL2...], where:
Below are examples of possible parsers with correct format:
These are examples of one entry. Entries can be combined with semicolon to define more than one parser:
AdditionalParsersList = FIX44; FIXT11:FIX50SP2; FIXT11:FIX50SP2,FIX50SP1; MyFixParser@FIXT11:FIX50SP2,FIX50SP1 |
Parsers are not used for Market Data Adapters and for FAST Sessions. |

This parameter specifies the number of attempts to restore the session.
The session is considered as restored if the telecommunication link was restored and the exchange of Logon messages was successful. If it is set to "-1", then the number of attempts is unlimited. This value is integer.
Optional. This parameter sets the time period after which a message rejecting is started while the session doesn't exist.
Value is specified in milliseconds (seconds*10-3), must be integer and greater than 0.
This parameter is an option whereby the version of FIX protocol used for the outgoing message is validated against that of the established session.
If set to "true", then the application must use the same version of the protocol as the established session otherwise an error occurs. If set to false then the application level message will be sent to the counterparty. The recommended value is "true".
Changing this value will impact the performance of FIX Engine. In the development should be true. In production should be false. |

| Deprecated since FIX Antenna 2.26. Correspondence between the key and certificate will be checked automatically. FIX Antenna does not establish a session if the key doesn't correspond to the certificate. |
Mandatory. Engine's SSL protocols to use.
It is a comma-separated list of protocols to use. Valid values are SSLv2, SSLv3, TLSv1, TLSv1_1, TLSv1_2.
Since some security issues with SSL v3 and RC4 encryption algorithm have been discovered recently and TLS 1.0, TLS 1.1 also contain known vulnerabilities, we strongly recommend using TLS 1.2 protocol. |
Optional. Whatever client's certificate is mandatory.
Decline clients without a valid certificate if true. The default value is false.
| Deprecated since FIX Antenna 2.26. Use SSLValidatePeerCertificate parameter instead. |
Optional. A certificate's password.
| Introduced in FIX Antenna 2.26 |
Optional. A private key's password.
Introduced in FIX Antenna 2.26 |
Optional. If set to "true" then client connections without a certificate will be rejected.
The default value is false.
Introduced in FIX Antenna 2.26. Use SSLValidatePeerCertificate parameter instead of deprecated SSLRequireClientCertificate. |
The parameter is optional. The default OpenSSL built-in configuration is used in case of the parameter absence.
The list is passed as is to OpenSSL during engine initialization in case of acceptor sessions (acceptor sessions are sharing the same configuration) and during session initialization in case of initiator sessions. See a list of the supported ciphers and list format is at official OpenSSL site: https://www.openssl.org/docs/man1.0.2/apps/ciphers.html
| Introduced in FIX Antenna 2.25.1 |
| The set of parameters below is applicable since FIX Antenna C++/.Net 2.24.0 |
The property enables TCP protection.
Valid values: true/false. The default value is false.
The property to specify connection timeout (in milliseconds) of waiting for logon.
Disable when equal to 0. The default value is 0.
The property will be enabled only if ProtectionTCP.Enabled = true
The property to specify a maximum of connections waiting for logon from one host. When the number of connections from the same host exceeds the specified value of the property, new connections will be rejected.
Disable when equal to 0. The default value is 0.
The property will be enabled only if ProtectionTCP.Enabled = true
Specifies the maximum size (in bytes) of the buffer to be able to avoid the situation when users end high-loaded garbage.
When the limit is exceeded, the connection will be closed and the corresponding reason will be written to the log.
The minimum size of the property which can be specified is 262144. If a lower value is specified in the property, it will be replaced with 262144 on the start of the FIXEdge.
If 0 is specified, there is no limit for the size of the buffer.
The default value is 0.
The property will be enabled only if ProtectionTCP.Enabled = true
AnchorFile
Optional. DBL TCP listen address and port.
Format: <XXX.XXX.XXX.XXX>:<port>.
Optional. This property tells how will be initialized Myricom DBL TCP API.
If true, it will use SocketAdaptor to emulate DBL API via generic sockets. The default value is false.
When it's set to true there is being enabled backward resolve based DNS entry spoofing detection mechanism in DNS related functions.
This option is disabled by default. |
If the parameter is enabled, a user should use Fully Qualified Domain Name (FQDN) or IP addresses as configuration/function parameters (e.g. 'workstation1.epam.com' instead of 'workstation1'). Otherwise, errors about DNS spoofing will be reported. |
Defines how to serialize UTCTimestamp or UTCTimeOnly field values:
0 - default mode - if the value of milliseconds is not equal to 0 then it will be serialized.
1 - always serialize milliseconds
2 - always truncate milliseconds
By default, this parameter is 0.
It is a global option for FixEngine. It works only when a value is passed as Engine::UTCTimestamp or Engine::UTCTimeOnly. |
