Pre-requisites
- You need a Quickfix/J installation to try out FIX samples. Please download and extract a Quickfix/J distribution into your local machine.
-
Configure the Executor sample FIX application (shipped with Quickfix/J)
to receive messages from Synapse and start it (refer FIX setup guide
for more details). In previous samples we only had a FIX 4.0 session configured
for Executor. For this sample we should also configure a FIX 4.1 session for
Executor. Therefore before starting it add the following entries to the
configuration file of Executor. (Do not remove or change the FIX 4.0
configuration already available in this file)
[session] BeginString=FIX.4.1 SocketAcceptPort=19877
- Enable the FIX transport listener and sender for Synapse (refer FIX setup guide for details).
-
Start Synapse using the configuration numbered 262 (repository/conf/sample/synapse_sample_262.xml)
Unix/Linux: sh synapse.sh -sample 262If the Executor was configured properly Synapse should establish 2 sessions with Executor upon startup (FIX 4.0 session and FIX 4.1 session)
Windows: synapse.bat -sample 262 -
Configure Banzai sample FIX application (shipped with Quickfix/J) to send
messages to Synapse and start it (refer FIX setup guide
for more details). You should also add the following entry to the Banzai
configuration file before starting it (replace $SYNAPSE_HOME with the actual
path to Synapse home).
DataDictionary=$SYNAPSE_HOME/repository/conf/sample/resources/fix/FIX40-synapse.xmlIf Banzai was properly configured, it should establish a FIX 4.0 session with Synapse upon startup. You should see some session logon messages on Synapse console and Banzai console.
Executing the Client
Send some order requests from Banzai to Synapse containing the synbols 'GOOG' and 'MSFT'. Synapse will forward the messages with the symbol 'GOOG' to the FIX 4.0 session. Messages containing the symbol 'MSFT' will be sent to the FIX 4.1 session. Any other messages will be simply dropped by the service bus since the default case of the switch mediator has been kept empty.
