    Domain Controller Failover Error

    Joseph Pugh Newbie

      I've read the WildFly book and the online documentation for configuring the Domain Controller failover.  I recently tested my setup and the following error was logged on the Host controller attempting to connect to the backup domain controller (actual IP address obfuscated):

       

      [Host Controller] 15:38:42,578 WARN [org.jboss.as.host.controller] (Controller Boot Thread) WFLYHC0001: Could not connect to remote domain controller remote://XXX.XXX.XXX.XXX:9999 – java.io.IOException: Unknown service name

       

      I haven't been able to find any information on this error.  I've tested networking and the port on the backup domain controller is available.  Here is the <domain-controller> entry from the Host controller attempting to connect

       

      <domain-controller>

              <remote protocol="remote" host="${jboss.domain.master.address:Y.YY.Y}" port="${jboss.domain.master.port:9999}" security-realm="ManagementRealm" username="user">

                <discovery-options>

                  <static-discovery name="discovery" protocol="${jboss.domain.master.protocol:remote}" host="${jboss.domain.master.address:X.X.X.X}" port="${jboss.domain.master.port:9999}"/>

                </discovery-options>

              </remote>

          </domain-controller>

       

      Thanks in advance to anyone who can share their ideas or provide insight into the error.  If needed I can provide additional configuration information.
