Hi all together,
i googled for a while and checked this forum but could not find an answer.
I got the following issue:
I set up a JBoss 7 cluster consisting of 2 nodes (a master and a slave) with the "domain configuration" (not standalone)
I adapted the host.xml on both nodes to use the hosts external IP interface in the <interfaces> section. I also configured the slaves <domain-controller> to the mastershost ip address.
So in general i only use IPs instead of hostnames.
Both hosts see each other in the network via IP or via DNS hostnames. Fine so far.
I configured a topic in the domain.xml (full-ha profile section). The topic can be seen in the admin console.
Then i developed a little test application with a JMS producer and a JMS consumer.
The idea is: I produce a message on any node and both nodes receive the message (the way it should be in a clustered environment).
The problem is: It does not work
After very long hours of investigation i stumbled upon /etc/hosts
There are 2 fundamental entries:
127.0.0.1 localhost
127.0.0.1 myownhostname
Our Linux admins said that the second line MUST be present so that myownhostname will be resolved to localhost.
Exactly that is my problem
If I specify the external IP instead of 127.0.0.1 the clustering works as intended.
So for some reason JBoss (HornetQ) uses the local hostname to do JMS although i only configured the JBoss with IP numbers.
My problem is that the Linux guys insist in the /etc/hosts entry to resolve the hostname with 127.0.0.1.
Any ideas how i can get the JBoss to work with such an entry?
I hope you understand my problem here.
Greetings
Volker
