5.3.1. Configure JVM Stack Preferences for IPv6 Networking

This topic covers enabling IPv6 networking for the JBoss EAP 6 installation.

Procedure 5.1. Disable the IPv4 Stack Java Property

  1. Open the relevant file for the installation:
    • For a Standalone Server:

      Open EAP_HOME/bin/standalone.conf.
    • For a Managed Domain:

      Open EAP_HOME/bin/domain.conf.
  2. Change the IPv4 Stack Java property to false:
    For example:
    # Specify options to pass to the Java VM.
    if [ "x$JAVA_OPTS" = "x" ]; then
       JAVA_OPTS="-Xms64m -Xmx512m -XX:MaxPermSize=256m -Djava.net.preferIPv4Stack=false 
       -Dorg.jboss.resolver.warning=true -Dsun.rmi.dgc.client.gcInterval=3600000 
       -Dsun.rmi.dgc.server.gcInterval=3600000 -Djava.net.preferIPv6Addresses=true"
