[jboss-user] [Clustering/JBoss] - Re: Does clustering require traffic over 1098 as well as 118
HAPartition logs a State was retrieved successfully message at DEBUG level; if you don't have that logging level enabled you won't see it. If you have DEBUG on and don't see it, there's a problem. I'll change that so it logs the receipt at INFO as well.

hi again! i've changed BindAddress in HA-JNDI and ServerAddress in JRMPInvokerHA. with iptables disabled (traffic can go freely) everything starts smothly but when i limit external interface to only accept petitions from outside i get some errors. actually, servers get clustered but i receive some bad messages from second server (first starts with no problem): [org.jboss.ha.framework.interfaces.HAPartition.SiapPartition] Fetching state (will wait for 6 milliseconds): here it get freezes for some time and then continues. should i receive some state was retrieved successfully message? can i ignore this issue or must i dig more? if you want further info, please just ask View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=3967179#3967179 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=3967179 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

thanks for the response but i dont really get it. in a multi-ethernet scenario where all clustering traffic is supossed to go through second/internal interface, why do i need to open also communication between first/external interface? is this by desing or is configurable anywhere? my goal is to separate all cluster related traffic from external traffic. maybe im not heading correctly the problem so i'll be glad to hear your comments.

Thanks for asking; we resolved this on our support portal and I forgot to post the result here. The issue is the RMI stub for the HA-JNDI service. Clients that connect to HA-JNDI use RMI as the transport, so each server running HA-JNDI creates an RMI stub for use in communicating with that server. When a client contacts the HA-JNDI service and downloads a proxy for that service, the proxy includes the RMI stubs for *all* the servers in the cluster. The presence of these stubs is what allows the proxy to fail over from one server to another if needed. So, say you have a 3 server cluster, A, B and C. A client contacts C (e.g. at port 1100) and downloads an HA-JNDI proxy. The proxy includes separate RMI stubs for A, B and C. How does C have a stub for A and B? When C joins the cluster, it fetches A and B's stubs, and sends its stub to A and B. The traffic Anne was seeing was the normal traffic of an RMI stub communicating back to its origin server for the purpose of maintaining a lease on the RMI server object. This lease is used by RMI's distributed garbage collection; without it the RMI server object could be gc'd. By default, this communication happens when the stub is first deserialized, and every 5 minutes thereafter. This communication is part of standard RMI stub behavior; it's not something JBoss wrote. The communication occurred on 1098 because that's the RMI port they had configured for HA-JNDI. By default in current versions of the AS, this port is 1101.

Can you post your JGroups protocol stack config? (IIRC you're using TCP).

Hi, I dont know if you have seen it already, but it comes in handy: http://wiki.jboss.org/wiki/Wiki.jsp?page=UsingJBossBehindAFirewall.

Hi Marc, thank you I have seen that document. I wonder if I haven't phrased my question well, but what I'm trying to find out is when a new member joins a cluster, does it make an RMI call to the existing member? So do the members of a cluster use RMI for any communication with each other? thanks Anne View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=3959964#3959964 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=3959964 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
