We have installed a new IDM 14.4. cluster on two wildfly-15.0.1.Final servers.
We want to use Unicast and we fed the IDM installation script the hostnames of our two servers, hotimmgmapp01 and hotimmgmapp02.
The IDM installation completes successfully on each server, but when we go to start up via ./standalone.sh we see the following error, and the IDM application fails to deploy:
MSC000001: Failed to start service org.wildfly.clustering.jgroups.channel.ee: org.jboss.msc.service.StartException in service org.wildfly.clustering.jgroups.channel.ee: java.lang.IllegalStateException: java.lang.IllegalArgumentException: java.security.PrivilegedActionException: java.lang.Exception: Property assignment of initial_hosts in TCPPING with original property value imgapp02,imgapp01 and converted to null could not be assigned.
Release : 14.4
Component : IdentityMinder(Identity Manager)
The inital_hosts under the TCPPING protocol underneath the JGroups subsystem requires the unicast port number to be present after the hostnames and surrounded by square brackets.
