How to enable heartbeat on EJB connections in JBoss EAP 7.2 wildfly-config.xml

Environment

• Red Hat JBoss Enterprise Application Platform (EAP) 7.2

Issue

• How to enable heartbeat on EJB connections in JBoss EAP 7.2 wildfly-config.xml

Resolution

In EAP 7.2 CP2+ , there is a default heartbeat-interval of 60000 ms (60 s) and default read-timeout of 120000 ms (120 s).

Configuring default for all connections (EAP 7.2 CP3+)

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <endpoint xmlns="urn:jboss-remoting:5.1" heartbeat-interval="30000" read-timeout="60000">
        <connections>
        </connections>
    </endpoint>
</configuration> 

Note: To be able to configure the default the xmlns must be urn:jboss-remoting:5.1

Configuring specific connections

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <endpoint xmlns="urn:jboss-remoting:5.0">
        <connections>
            <connection destination="remote+http://host1:8080" read-timeout="60000" write-timeout="60000" heartbeat-interval="30000"/>
            <connection destination="remote+http://host2:8080" read-timeout="60000" write-timeout="60000" heartbeat-interval="30000"/>
        </connections>
    </endpoint>
</configuration>
