Overview

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")

Engine parameters

EngineRoot

The top of the directory tree under which the engine's configuration and log files are kept.

DO NOT add a slash at the end of the directory path.

ListenPort

Optional. Engine's listen port.

Supports multiple values delimited by comma.

LogFileName

Optional. Engine's log file name. If this parameter is commented or empty, LogFileName = "engine.log" as default.

Actually represents the alias for the "Log.Engine.File.Name" parameter. If both parameters are specified simultaneously, then:

If Log.Engine.Device is not specified, "LogFileName" is used;
If Log.Engine.Device is specified, "Log.Engine.File.Name" is used;

ListenAddress

Optional. Engine's local IP address to bind to.

It can be used on a multi-homed host for a FIX Engine that will only accept connect requests to one of its addresses. If this parameter is commented or empty, the engine will accept connections to any/all local addresses.

LicenseFile

The license file path.

LogDirectory

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.

ConnectAddress

Optional. Engine's local IP address to send messages from.

It is used only for multi-homed hosts If this parameter is commented or empty, the engine will send IP datagrams from any/all local addresses.

NumberOfWorkers

A number of threads that serve FIX sessions (heartbeat generation/check, message rejecting, message delay delivering, etc) On Linux the recommended value is 2.

On other platforms the recommended value is 10. The value must be integer and greater than zero.

Changing this value will impact upon the performance of FIX Engine.

Workers are used for the following operations:

Process incoming connections (for acceptors) until incoming Logon message is delivered
Initiate session reconnect (for acceptors) when logout is received and Application marks session to connect again
Process outgoing connections (for initiators) until TCP connection is established and outgoing Logon is sent in case async connect is used
Deliver rejected messages back to Application if EnableMessageRejecting = true and message cannot be sent on time
Deliver delayed messages to Applicationwhenfirstcallofprocess() returns false

OutOfSequenceMessagesStrategy

Optional. This parameter sets strategy for processing out-of-sequence messages. Parameter is available since FIX Antenna 2.23.0
Valid values:

RequestAlways - send resend request with BeginSeqNo (7) = <out-of-sequence message number>, EndSeqNo (16) =0 on any out-of-sequence message.
RequestOnce - send the only resend request on the gap. Duplicates of resend requests for the same interval are not sent.
IgnoreGap - send resend request on gap and process out-of-sequence messages.
Queue - use temporary queue for storing out-of-sequence messages and process them after the gap is closed.

Is not supported for FAST sessions

Default value: RequestAlways.

OutOfSequenceMessagesStrategy.QueueSize

Optional. The size of temporary queue for processing out-of-sequence messages (measured in a count of messages). The parameter is used if parameter OutOfSequenceMessagesStrategy=Queue. Parameter is available since FIX Antenna 2.23.0

Default value is 2000.

A queue should be cleared after exceeding the limit out-of-sequence messages and a new resend request should be sent.

Session parameters

LogonTimeFrame

This parameter sets the time period after which a session is non-gracefully terminated if a response is not received to a first "Logon" message (message type A).

The corresponding Logout message is sent to the counterparty. This value is in seconds. The recommended value is 30 seconds for dedicated connections or private networks. Trading connections via the internet will require calibration. If it is set to "0", then the time period is unlimited. The value must be integer and not negative.

LogoutTimeFrame

This parameter sets the time period after which a session is automatically terminated if a response is not received to a "Logout message" (message type 5).

This value is in seconds. The recommended value is 10 seconds for dedicated connections or private networks. Trading connections via the internet will require calibration. The value must be integer and greater than 0.

IntradayLogoutTolerance

An option not to reset sequence numbers after Logout.

Valid values:

true - enables IntradayLogoutTolerance mode;
false - disables IntradayLogoutTolerance mode.

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.

ReasonableTransmissionTime

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 then Engine sends a TestRequest message. If the required Response Heartbeat message is not received during Heartbeat interval plus Delta then the session moves to the state "Telecommunication link failed". This parameter is specified in (Heartbeat Interval/100). The recommended value is twenty percent.

ForceSeqNumReset

This parameter allows to resolve sequence gap problem automatically.

When mode is ON session uses 141(ResetSeqNumFlag) tag in sending/confirming Logon message to reset SeqNum at the initiator or at the acceptor. Valid values:

"0" or "false" - Disable ForceSeqNumReset mode;
"1" or "true" - Enable SeqNum reset at first time of session initiation;
"2" - Enable SeqNum reset for every session initiation.

DuplicateResendRequestLimit

Specifies how much same ResendRequests received before Application::onResendRequestLoop is called.

This option is disabled if value is less than 2.

AdditionalParsersList

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 AdditionalParsersList parameter.

Format of the value: [UNIQUE_PARSER_NAME@][FIXT_PROTOCOL1:]APP_PROTOCOL1[,APP_PROTOCOL2...], where:

UNIQUE_PARSER_NAME - optional, name of the parser;
FIXT_PROTOCOL1 - optional, session protocol. Required if APP_PROTOCOL doesn't contain session messages;
APP_PROTOCOL1 - required, application protocol;
APP_PROTOCOL2, ... - optional, list of other application protocols.

Below are examples of possible parsers with correct format:

MyFixParser@FIXT11:FIX50SP2,FIX50SP1;
FIXT11:FIX50SP2,FIX50SP1;
FIXT11:FIX50SP2;
FIX44.

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.

ThirdPartyRoutingIsEnabled

FIX Engine has inbuilt FIX message routing capability and fully supports the "Deliver To On Behalf Of" mechanism as specified by the FIX protocol.

If this parameter is set to "true" then Engine will redirect FIX messages automatically to other FIX sessions it maintains if OnBehalfOfCompID field in the message is defined. If this parameter is set to "false" Engine directs all messages received to the client application.

DelayedProcessing.DeliveryTriesInterval

This parameter specifies the time interval between attempts to deliver an application level message to a registered client application in the event the application does not confirm receipt and operation upon the message.

DelayedProcessing.MaxDeliveryTries

Optional. This parameter specifies the number of attempts that will be made to deliver an application level message to the registered client application.

If this value is exceeded then the session will be closed with the logout reason "Application not available". The recommended value is 10. The value must be integer and not negative.

Reconnect.Interval

This parameter specifies the time interval between reconnection attempts in order to restore a communications link.

This value is specified in milliseconds (seconds*10-3). The recommended value is 1000 for dedicated connections and private networks. Internet connections require calibration. The value must be integer and greater than 0.

Reconnect.MaxTries

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.

MessageTimeToLive

Optional. This parameter sets the time period after which a message rejecting is started while session doesn't exist.

Value is specified in milliseconds (seconds*10-3), must be integer and > 0.

CheckVersionOfOutgoingMessages

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 upon the performance of FIX Engine. In the development should be true. In production should be false.

ResendMessagesBlockSize

Resend Request resend messages by blocks.

This parameter defines how many messages proceed in block. The value “0” means that all messages will be resend in one block. The value must be integer and not less than 0.

The default value is "1000".

Introduced in FIX Antenna 2.26

Storages

LogIncomingMessages

This property provides an option to log incoming FIX messages (those received) from a counterparty FIX Engine.

They will be stored in the directory specified by the LogDirectory parameter in a file with extension "in".

Changing this value will impact upon the performance of FIX Engine. In the development should be true. In production should be false.

OutgoingMessagesStorageSize

This parameter defines the upper limit to the number of outgoing messages that are resent in the event of a Resend Request.

The recommended value is 20000 if no data on mean activity is known.

Changing this value will impact upon the performance of FIX Engine. Large storage increases application working set.

ExtraSafeMode

If this parameter is true than file streams are flushed after each I/O operation.

Changing this value will impact upon the performance of FIX Engine. In the development and in production should be true.

TimestampsInLogs

Optional. An option to write timestamps in the log files.

The default value is true.

Changing this value will impact upon the performance of FIX Engine. In the development should be true. In production should be false.

EnableIncrementalLogFileCreation

Setting property "true" will reserve 10Mb of disc space for logging.

If log reaches 10Mbs, another 10Mbs will be reserved and so on. When property is "true" FixAntenna performance is greatly increased.

Persistents.LogIncrementSize

Specifies amount of memory in bytes reserved for memory mapped file message storage for *.out/*.in files.

It defines how FIX Antenna reserves space on the HDD for PersistentMM (in any cases) and Persistent (if EnableIncrementalLogFileCreation is ON). It is recommended to set large enough value to minimize number of resizes during the storage life time. Each resize can cause latency spike.

Changing this value will impact upon the performance of FIX Engine.

Persistents.IdxIncrementSize

Specifies amount of memory in bytes reserved for memory mapped file message storage for *.idx file It defines how FIX Antenna reserves space on the HDD for PersistentMM (in any cases) and Persistent (if EnableIncrementalLogFileCreation is ON).

It is recommended to set large enough value to minimize number of resizes during the storage life time. Each resize can cause latency spike.

Changing this value will impact upon the performance of FIX Engine. In the development should be true. In production should be false.

SplitPersistentMsgStorage.BackupDir

This property is the path to the directory, where sliced message storage will search for log files in case they are not found in the primary location.

It is user responsibility to move files from the primary location to backup. The default value is empty - backup path disabled.

SplitPersistentMsgStorage.MaxSliceSize

Specifies maximum size of one slice for sliced message storage.

Storage slices are created with step, specified with Persistents.LogIncrementSize parameter value. If MaxSliceSize value is no multiple of Persistents.LogIncrementSize,result file size willbeless, than specified. If value is less than LogIncrementSize, LogIncrementSize value will be used.

Recommended value: any multiple of Persistents.LogIncrementSize Default value is 500000000 - 500Mb.

MessageStorage.IndexRebuildEnabled

Optional. If this parameter is true, FIX Engine will try to restore the index file from the log file in case the index file is missed or corrupted. The default value is false.

Please be careful when you enable this property: restoring process uses some heuristic algorithms, and some data (not messages) could be missed.

MessageStorage.RequireRejectFlagSupport

Optional. If this option is enabled, FIX Engine will not rebuild index files for message storages, that does not support embedded Reject Flag Marker. The default value is true.

MessageStorage.TimestampUnit

This property specifies precision of timestamps in session logs (.in / .out storage files).
Possible values are: "millisecond", "microsecond", "nanosecond".

Optional. The property is global for all sessions. The default value is "millisecond".

Unregistered Acceptors parameters

CreateUnregisteredAcceptorSession

This parameter provides an option whereby FIX Engine will accept a FIX session for which it has no registered application (an acceptor).

If set to "true" Engine accepts incoming connection and creates corresponding Session object. If there is no Application associated with session, all application level messages are rejected with Application Level Reject(3) message. If an application is registered, the behavior is as standard. If set to false then Logon messages are ignored and incoming connection is dropped. Property is obsolete, UnregisteredAcceptor.CreateSession should be used instead.

UnregisteredAcceptor.CreateSession

This parameter provides an option whereby FIX Engine will accept a FIX session for which it has no registered application (an acceptor).

If set to "true" Engine accepts incoming connection and creates corresponding Session object. If there is no Application associated with session, all application level messages are rejected with Application Level Reject(3) message. If an application is registered, the behavior is as standard. If set to false then Logon messages are ignored and incoming connection is dropped.

UnregisteredAcceptor.IgnoreSeqNumTooLowAtLogon

This parameter allow to resolve seqNum too low problem at logon.

When it true - session continue with received seqNum.

UnregisteredAcceptor.maxMessagesAmountInBunch

FA able to join packages that wait for sending into the socket, this parameters controls how many messages could be joined.

0 means infinite. Value should be less than 1000000.

UnregisteredAcceptor.RejectMessageWhileNoConnection

When true, unregistered acceptors will reject messages in case they couldn't be sent during the interval specified in the MessageTimeToLive parameter.

You can find more information about how to use this parameter here: How to use "RejectMessageWhileNoConnection" parameter

UnregisteredAcceptor.tcpBufferDisabled

When true, the TCP buffer (Nagle algorithm) will be disabled for unregistered acceptors.

Otherwise, TCP may join and enqueue small packages until timeout ends.

UnregisteredAcceptor.SessionStorageType

Default storage type of created unregistered sessions.

By default persistentMM storage type used. Use "transient" value to use transient storage for the sessions.

Message Validation parameters

MessageMustBeValidated

Mandatory. Defines whether each application message is checked for the existence of required tags.

Valid values: "true" | "false"

If set to ‘true’ then all application-level messages are checked. If set to ‘false’ then the responsibility for message validity rests with the counterparty.

Note: Session level messages are checked in all cases. The recommended setting is ‘false’. Changing this value will impact up on the FIX Engine performance. Use ‘true’ for debugging and ‘false’ to increase performance.

Default value: MessageMustBeValidated = false

VerifyTagsValues

Optional. Defines whether each application message is verified for tag values

Valid values: "true" | "false"

If set to ‘true’ then all messages will be verified. If set to 'false' then the responsibility for message verification rests with the counterparty.

Note: Ignored if MessageMustBeValidated = false

Default value: VerifyTagsValues = true

ProhibitUnknownTags

Optional. Defines whether each application message is checked for the unknown tags.

Valid values: "true" | "false".

If set to ‘false’ then all application messages with unknown tags will be handled. If set to ‘true’ then the engine will reject messages with unknown tags.

Note: Ignored if MessageMustBeValidated = false

Default value: ProhibitUnknownTags = false

VerifyReperatingGroupBounds

Optional. Defines whether each application message is verified for repeating group size.

Valid values: "true" | "false".

If set to ‘true’ then the engine will reject messages with incorrect repeating group size. Otherwise, the message will be passed to the application layer. In this case, the responsibility for message validity rests with the counterparty.

Note: Ignored if MessageMustBeValidated = false

Default value: VerifyReperatingGroupBounds = true

VerifyReperatingGroupBounds = "false" has no effect since FIX Antenna 2.26

IgnoreUnknownFields

Mandatory. If true then any undefined field that is unknown to the dictionary will be ignored. Should be false for development, true for production because if false FA stores all unknown fields in the FIXMessage in the list on the heap. With true it would ignore these fields thus limit storage on a heap

Valid values: "true" | "false".

Important: this value has priority over all other validation settings: Even If (MessageMustBeValidated = true and (ProhibitUnknownTags = true or VerifyTagsValues= true)) unknown fields are ignored.

Warning: Changing this value will impact upon the performance of FIX Engine.

Note: Ignored if MessageMustBeValidated = false

Default value: IgnoreUnknownFields = false

Validation.CheckRequiredGroupFields

Optional. Controls the validation of required fields inrepeatinggroup.

Valid values: "true" | "false".

If set to ‘true’ then repeating groups will be checked for the presence of required fields. If set to ‘false’ then the responsibility for repeating group validity rests with the counterparty. The recommended setting is 'true'.

Note: Ignored if MessageMustBeValidated = false

Default value: Validation.CheckRequiredGroupFields = true

AllowZeroNumInGroup

Mandatory. Defines whether the leading group tag with "0" value will be ignored.

Valid values: "true" | "false".

If set to ‘true’, a leading group tag with “0” value will be ignored in a raw message. Otherwise, an exception will be fired.

Default value: AllowZeroNumInGroup = false

AllowEmptyFieldValue

Mandatory. Defines whether the raw message may contain tags without values.

Valid values: "true" | "false".

If set to ‘true’, the raw message may contain tags without values that will be ignored.Otherwise an exception will be fired.

Default value: AllowEmptyFieldValue = false

Logging parameters

Log.File.Format

Customformatoflogfilerecord. Can be defined separately for each log file e.g. Log.Version.File.Format = ...

Format string can contain any symbols and keywords:

%% - put '%' symbol;
%level - put severity level name: 'ERROR', 'WARN' etc.;
%tablevel - put extra spaces for vertical alignment of records after %level;
%date{FIX} - date in 'YYYYMMDD-HH:MM:SS.sss' format;
%date{ISO8601} - date in 'YYYY-MM-DD HH:MM:SS,sss' format;
%date - date in 'DD MMM YYYY HH:MM:SS,sss' format;
%timezone - time zone abbreviation or name (setup TZ env variable to take abbreviation in windows) or 'UTC';
%logger - log category, component;

%message - logged message.

Default value:

Log.File.Format = [%level] %tablevel%date{FIX} [%thread] [%logger] - %message

Log.File.CreateUniqueFileName

If true new unique file name will be created. Log.File.Name value is a pattern.

If false Log.File.Name will be used as file name.

If Log.Device is not specified explicitly (in other words, Log.Device = "File" as default), Log.File.CreateUniqueFileName = "false" as default.

Log.Cycling

Enables/disables log file cycling.

Valid values:

true - to enable cycling;
false - to disable cycling.

If set to true, then repeating records in logs will be controlled and replaced with the single "cycling record" according to the specified cyclling parameters. Seecyclling parameters described below for details.

Log.Cycling.Ignore

Number of repeating records to be placed to log before cycling is started.

Example: Log.Cycling.Ignore = 3

Log.Cycling.BlockSize

Number of repeating records to be accumulated (hidden) before write the "cycle record" to the log.

Example: Log.Cycling.BlockSize = 10

Log.Cycling.Multiplier

Multiplier for the BlockSize. If BlockSize number of messages is accumulated and the same message still appears then next BlockSize is calculated as the previous one multiplied by Multiplier.

Example: Log.Cycling.Multiplier = 10

Log.Device

Default target devices.

Valid values:

File - messages will be written to the file;
Console - messages will be written to the console;
EventLog (Windows specific) - messages will be written to the Windows Event Log;
WinDebug (Windows specific) - messages will be written to the OutputDebugString;
Syslog (Linux/Unix specific) - messages will be written to the system log.
Log4Cplus - messages will be written to Log4Cplus (since FIXEdge version 6.7)

If Log.Device is not specified explicitly, Log.Device = "File" as default.

The properties of the device are in the "Log.<name>" section. For instance Log.File contains all properties of the File device.

Multiple devices can be chosen - the names of devices should be separated by a space in this case. E.g.: by setting Log.Device = File Log4Cplus logging will be performed with both creating standard log files and forwarding to Log4Cplus.

Log4Cplus can be used to send log messages to external services such as Splunk. FIXEdge does not guarantee each log message delivery when:

Log message receiver is not available (not listening on the given port).
Log message receiver thoughput is less than log flow produced by FIXEdge.

In these cases FIXEdge will drop the messages it was unable to send.

Log.EventLog.EventSource

A string that specifies the name of the source. The source name must be a subkey of a log file entry under the EventLog key in the registry.

For example, "WinApp" is a valid source name if the registry has the following key: "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Event Log\Application\WinApp".

Log.File.AutoFlush

If set to true then buffer will be flushed after each logging call.

If set to false then flush is not called.

Setting to true decreases program performance; setting to false increases a risk of records loss in case of program failure.

Log.File.Backup.Time

Optional. Local time when logs should be backed up. When the specified backup time comes, the scheduler moves log files to the specified backup directory.

Should be in format 'hh:mm' or 'hh:mm:ss'.

Log.File.Locked

Valid values:

true - lock log file;
false - do not lock log file.

Log.File.Recreate

If true then file will be recreated on each start.

If false then new records will be appended to the existent file.

Log.File.RootDir

The root directory for log files. It will be concatenated with each file name specified by 'Log.File.Name'. If Log.Device is not specified explicitly (in other words, Log.Device = "File" as default), Log.File.RootDir = LogDirectory as default.

You can find more information about how to configure paths to log files here: How to configure paths to FIXEdge log files.

Log.File.Rotate

Affinity parameters

WorkerCpuAffinity

Defines an affinity mask for all worker pool threads.

Affinity is specified as bit mask where the serial number of the bit is the serial number of the core if read from the right to the left. Mask should be presented in the decimal system.

E.g. to specify second, third and fourth cores, the affinity in bytes will look like "1110". It is "14" in the decimal system. So, for proper use the property should be set in the following way:

WorkerCpuAffinity = 14
