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

Please refer to the Quick Start Guide for installation instructions and setup several nodes on different boxes. After the installation, update the Hazalcast configuration (conf/cluster.xml):

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

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

2. Enable the Hazelcast Cluster Quorum mechanism 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>1</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
