[jboss-jira] [JBoss JIRA] (WFCORE-316) Slave host does not register to DC when starting with --cached-dc and DC is available

[Brian Stansberry (JIRA)]

    [ https://issues.jboss.org/browse/WFCORE-316?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13196791#comment-13196791 ] 

Brian Stansberry commented on WFCORE-316:
-----------------------------------------

Another note: the reason persistence of changes to domain.cached-remote.xml can't happen even if the slave connects to a DC is because in the --cached-dc case we use this ConfigurationPersister:

https://github.com/wildfly/wildfly-core/blob/master/host-controller/src/main/java/org/jboss/as/host/controller/ConfigurationPersisterFactory.java#L142

The store() method logs a warn and then returns a no-op PersistenceResource.

I think it probably can just not override the superclass, which is what BackupRemoteDomainXmlPersister just above it does.

> When a slave host is started with --cached-dc option it won't register to Domain Controller although it's available. domain.sh help says "If this host is not the Domain Controller and cannot contact the Domain Controller at boot, boot using a locally cached copy of the domain configuration (see --backup)" and this is not really happening because slave host never contact to DC with --cached-dc
