1. Re: AS7 configure domain, what exactly has to altered in host.xml and domain.xml
wdfink Dec 22, 2011 4:36 AM (in response to martineikelboom)You have one domain controller (the one with domain-controller.local in the host.xml).
This one must be started first and have a server-group (see domain.xml) main-server-group.
Each host.xml define a server and join a server-group of the domain.
you might have a look to https://docs.jboss.org/author/display/AS7/Domain+Setup
If you have problems please attach the domain.xml and host.xml's and the appropirate server logfile.

2. Re: AS7 configure domain, what exactly has to altered in host.xml and domain.xml
martineikelboom Dec 22, 2011 5:58 AM (in response to wdfink)Is it possible to set this up using 1 IP address?
Or is it required to distinguish the servers on the basis of IP address?
I have multiple standalone servers installed, and I want to configure 1 server as domain controller/host controller, and the others as slaves.
Would be good to get an example, so I can see what is required to be different, altered, default, etc.

3. Re: AS7 configure domain, what exactly has to altered in host.xml and domain.xml
wdfink Dec 22, 2011 6:26 AM (in response to martineikelboom)You might use the same or different IP addresses.
If you look into a fresh installation there is an example of a domain configuration.
If you start the domain there are 3 servers (you have to set auto-start true within the host.xml)
The server start with a port-offset instead of using different ip addresses.
The next host you have to change port-offset or use '-b' during start to set the IP address on the same machine.
Helpful descriptions you will find in the domain setup document (link above)

4. Re: AS7 configure domain, what exactly has to altered in host.xml and domain.xml
martineikelboom Dec 29, 2011 3:14 AM (in response to wdfink)I managed to get a domain configuration going. My understanding is that I now have 1 host controller, and this controls 3 servers, including itself. These servers reside on the same host, although they are called hosts in the configuration files.
I would like to know then what is the definition of a host.
My aim is:
3 separate servers which I consider hosts. I want to link those hosts with the host controller. How do I configure that?
if this is possible, then why the offset, if these hosts all have there own IP range?
I also miss documentation on High Availabilty for release 7.0. Should I be refering to another version for similar concepts?

5. Re: AS7 configure domain, what exactly has to altered in host.xml and domain.xml
martineikelboom Jan 6, 2012 8:52 AM (in response to martineikelboom)Has anybody got an answer to
1. why the offset if they are on different hosts with differing IP numbers. What is the difference to a cluster with offset IPnumbers and cluster on differing hosts
2. how does the host controller start and stop a slave server, or do you have to start these separatly?
3. doc HA version 7 location? Is the version 5 HA comparable to version 7 in regards to HA concepts and configuration?

6. Re: AS7 configure domain, what exactly has to altered in host.xml and domain.xml
wdfink Jan 6, 2012 5:45 PM (in response to martineikelboom)1. You might use port-offset and/or different IP bindings. Functional there is no difference.
It might be easier to track cluster stuff if you have different IPs, otherwise it can be difficult to differing the instances
I would recommend to use one strategie per environment, i.e. IP binding with original ports for test and changed ports for production
2. A host controller will start/stop instances by request it via domain management interface (HTTP or CLI).
The domain cotroller will be the master.
If you add a new host-controller to a domain (start a instance with domain.sh and have a remote domain address)
the host will connect the domain-controller, push the configuration and start the server configured in its host.xml
3. The documentation is not ready yet, see https://docs.jboss.org/author/display/AS71/High+Availability+Guide
concept will be still based on JGroups but the configuration will be completely different
