[jboss-jira] [JBoss JIRA] (AS7-5907) Assign an unique NodeID automatically

[Tom Jenkinson (JIRA)]

    [ https://issues.jboss.org/browse/AS7-5907?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12732797#comment-12732797 ] 

Tom Jenkinson commented on AS7-5907:
------------------------------------

This was deferred in JBTM, but I think it might be something AS7 would like to provide for usability aspects.

Generally: assuming the user does not define the node-identifier themselves, use Cleberts algorithm to persistently store a unique node-identifier.

Note the node-identifier must be unique for any server that talks to another server or shares an object store, it may be that UUID is not considered unique enough.

> It shouldn't be needed to assign the node-id manually IMO.
> You could store the node-id on a file and recover it for subsequent starts.
> On hornetQ for instance, we look for the nodeID on a file, if the file doesn't exist we assign a UUID and write to the file.
> In our previous experience UUID would be a best fit to assign the nodes since that was the only way we could guarantee unique IDs between the nodes.
