[jboss-jira] [JBoss JIRA] Commented: (JBCLUSTER-220) HAPartition.callMethodOnCluster() is not reentrant

[Brian Stansberry (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBCLUSTER-220?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12451173#action_12451173 ] 

Brian Stansberry commented on JBCLUSTER-220:
--------------------------------------------

Yes, these can be ignored. Better yet, remove the attributes mentioned from the channel configurations in the AS so the WARNs will go away.

The standard configurations in AS 4.x are not optimized for JGroups 2.6; perhaps you would be better off replacing them with ones based on the "udp" or "tcp" protocol stack configs in AS 5's ChannelFactory (see http://www.jboss.org/community/docs/DOC-13186 for discussion of where that is in AS 5). This would be a cut-and-paste exercise + changing the mcast_port (to make the port unique for each channel) and removing the singleton_name attribute from UDP/TCP.

If you have more questions about this move, please start a thread on the "Clustering User" forum, rather than mixing the discussion in here.

> An RPC handler of callMethodOnCluster() cannot in its turn call callMethodOnCluster() querying other services. The second call blocks until timeout is reached and returns without results.
> The same relates to facilities based on this method like Distributed Replicant Manager.
