What you mean? A backup option for a host controller?
Sounds not as a real use-case as the ip addresses might different.
Or am I understand something wrong?
My apologies for the confusion.
| A backup option for a host controller?
According to the JBoss EAP BETA documentation a host controller that was started with the
--backupoption can be promoted to act as the domain controller. Which I think it means that you start a host server like ./domain.sh --backup, then it will act like a domain controller backup.
Instead of doing it as a script parameter, I would like to specify that a host controller is a back-up domain controller in either the host.xml or domain.xml. Is that possible? Thanks!
No --backup means that the (slave) HC will store a backup of the domain configuration.
If the DC has failed you can start this HC with --cahced-dc instead and the domain configuration backup will be used and the HC act from now on as the DC.
There is no other way, especially no hot-standby as DC-failover
