I've gone with this
option in standalone mode, writes to the model are not backed up until the standalone
server has successfully booted.
Now, the question is when the domain is considered to be properly started?
-Once we are ready to start the servers? Bad config in host/domain here could screw up
startup for one or more servers.
-Once all the servers have been started successfully? If a server does not start for
whatever reason we won't get the domain files backed up.
For the command line stuff, I am adding this extra system property for standalone mode
(default value is 'standalone.xml':
-Djboss.server.config.file
and these two extra possible properties for the command line for domain mode:
-Djboss.domain.config.host
-Djboss.domain.config.domain
The default values will be 'host.xml' and 'domain.xml'.
If specified it can either be a full path:
-Djboss.domain.config.host=/somewhere/blah/some-host.xml
Or if a simple name, a file in jboss.domain.config.dir:
-Djboss.domain.config.host=special-host.xml
Or any of the backed up files using the known prefixes:
-Djboss.domain.config.host=initial
-Djboss.domain.config.host=last
-Djboss.domain.config.host=original
-Djboss.domain.config.host=v4
