FIXEdge Java packages are cluster ready. Minimal changes are required.

...

1. Define a unique node name for each instance (conf/cluster.xml):

   Code Block
   language xml
   <instance-name>fej1</instance-name>

   
   

2. (Optional) If Hazelcast Cluster Quorum mechanism must be used, then it is required to enable it and define the minimum number of machines required in a cluster for the cluster to remain in an operational state (conf/cluster.xml):

   Code Block
   language xml
   <quorum enabled="true" name="fixedgeJQuorum"> <quorum-size>2</quorum-size> </quorum>

   Please note that the minimum value for quorum-size is 2.

3. Update the profile parameter to fej-ha in wrapper configuration (conf/wrapper.conf) to enable the HA functionality:

   Code Block
   language powershell
   # Java Additional Parameters wrapper.java.additional.1a = -Dspring.profiles.active=fej-ha

   
   

4. Define parameters for FIX session replication in session configuration (for example, in conf/session/samples/s_fixDefault.propertiesto enable for all FIX session samples)

   Code Block
   language powershell
   # use the Persistence API for storing the FIX session state storageFactory=com.epam.fixengine.storage.persistence.PersistenceEnableFactory # use the Persistence API implementation with replication between nodes storage.persistenceFactoryBuilder=com.epam.fixengine.storage.persistence.ReplicatedPersistenceFactoryBuilder # replication timeout in milliseconds. A zero value for this option will enable asynchronous replication for the FIX session. replicationTimeout=0
