JDG Configuration Files

A JDG instance intended to provide access to an internal local cache (maintained within the memory of the JVM running the JDG instance) is configured from $JDG_HOME/standalone/configuration/standalone.xml A JDG instance intended to cluster with other instance to provide a distributed cache space is configured from $JDG_HOME/standalone/configuration/clustered.xml.

The clustered instance is supposed to be started using $JDG_HOME/bin/clustered.sh. When started this way, the configuration file $JDG_HOME/bin/clustered.conf is sourced. However, when systemctl starts the instance, the systemd startup scripts are written to invoke $JDG_HOME/bin/standalone.sh -c clustered.xml and this sources standalone.conf and not clustered.conf. It is best to keep both of those in sync with configuration.

JDG Main Configuration File

The JDG main configuration fille is standalone.xml or cluster.xml, depending the mode JDG is started in. Relevant sections:

infinispan:server:endpoint Section

This is the section where various connectors (HotRod, memcached and REST) are configured.

<subsystem xmlns="urn:infinispan:server:endpoint:6.1">
  <hotrod-connector cache-container="clustered" socket-binding="hotrod">
    <topology-state-transfer lazy-retrieval="false" lock-timeout="1000" replication-timeout="5000"/>
  </hotrod-connector>
  <memcached-connector cache-container="clustered" socket-binding="memcached"/>
  <rest-connector cache-container="clustered" auth-method="BASIC" security-domain="other" virtual-server="default-host"/>
</subsystem>

Procedures

• Add a Custom Cache
• Switch Clustering from Multicast to TCP
