[jboss-jira] [JBoss JIRA] Commented: (JBAS-6307) Cross-cluster cross-talk on JBM-DATA channel

[Kevin Lohmann (JIRA)]

    [ https://issues.jboss.org/browse/JBAS-6307?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12576529#comment-12576529 ] 

Kevin Lohmann commented on JBAS-6307:
-------------------------------------

The file jgroups-channelfactory-stacks.xml in all\production\web server contains the configuration

<MPING timeout="5000" mcast_addr="${jboss.jgroups.jbm_data.mping_mcast_addr:228.6.6.6}" [..] />

So no improper syntax, but not the above given config

<MPING timeout="5000" mcast_addr="${jboss.partition.udpGroup:228.6.6.6}" [..] />

Mean both values for mcast_addr the same?

> The configuration syntax in the jbm-data protocol stack config's MPING.mcast_addr attribute is not understood by the JGroups parser; it's syntax only supported by the String property replacement code in jboss-common-core.jar.
> <MPING timeout="5000" mcast_addr="${jboss.messaging.datachanneludpaddress,jboss.partition.udpGroup:228.6.6.6}"
> will be evaluated by JGroups as "use value for system property 'jboss.messaging.datachanneludpaddress,jboss.partition.udpGroup', if not found use 228.6.6.6".  Which results in 228.6.6.6.
> Fix is to replace with 
> <MPING timeout="5000" mcast_addr="${jboss.partition.udpGroup:228.6.6.6}"
> in which case setting -u at AS startup will set jboss.partition.udpGroup, which JGroups will find and use.
