According to my experience ,the reason is that if Apache during jk2 initialization does not find some JBoss node, it exclude it from the list and will not try it again. what happen if one of jboss server failed in the cluser,I have to restart this jboss server while the apache and all of others jboss server are still runing? do I have to stop the apache,wait for this jboss server started,the restart the apache? if so,the web site has to stop for a moment. If JBoss after some successful period failed to respond to jk2 request, Apache will try it again, so you can safely restart failed JBoss instance, and it will be recognized by Apache without Apache restart.

There is not.

According to my experience with Jetty, sticky sessions
did not work
for (web.xml) web applications by

the same is valid for Tomcat. Do you use this tag?

I use mod-jk2 from beginning, and it works.

Re: [JBoss-user] [Clustering/JBoss] - Re: JMS queues started on both nodes in a cluster after temp
Not exactly the same issue because you use a TCP-based stack, whereas JBoss Clustering by default uses UDP (IP multicast). crobert wrote: Hello, That looks like the same problem I'm having in http://www.jboss.org/index.html?module=bb&op=viewtopic&t=45855 with JBoss 3.2.3.

Re: [JBoss-user] [Clustering/JBoss] - TCPGOSSIP clustering problem with server restart
That is a well-known bug. I have fixed this in JGroups (CVS head), and will release a new version hopefully within the next 2-3 weeks. If you can't wait, simply checkout JGroups from CVS, do a build.sh jar-1.4 and copy the resulting jgroups-all.jar into your server dir as jgroups.jar.

However I noticed that in the following scenario, the cluster is not always formed: 1. Start GOSSIP server 2. Start JBoss on my first machine 3. (after the first machine JBoss starts successfully) Start JBoss on my seconds machine. 4. The cluster is formed and I get load balancing. 5. If I kill server 1 and restart it before the GOSSIP server detects that the first node is dead, in most of the cases, the cluster is not formed back, although the GOSSIP server on trace mode detects as having two servers in the cluster (and accepts connections from both of the servers). The two nodes no not see each other and I don't have failover or loadbalancing: all requests go to only one server. Is this the expected behavior ?

Re: [JBoss-user] [Clustering/JBoss] - Re: Auto-discover node in the client
kaobe wrote:
Hello again,
I don't know why, but I'm still (again?) facing problems concerning
cluster node auto detection.
I have now the following properties for the InitialContext:
Properties prop = System.getProperties();
prop.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
prop.put("java.naming.factory.url.pkgs",
"org.jboss.naming:org.jnp.interfaces");
prop.put(Context.PROVIDER_URL, "");
I think these are right because sometimes I get a connection and am
able to lookup my stateless session bean.
But most of the times it doesn't work. I think it works more often
when I started the cluster nodes freshly, but I don't know if that is
just my imagination.
It would be really great if somebody could help me with this problem.
Perhaps someone out of the JGroups team.
By the way, here is the stacktrace of the exception when my client
doesn't get a connection.
javax.naming.CommunicationException: Receive timed out. Root exception
is java.net.SocketTimeoutException: Receive timed out

HA-JNDI discovery is *not* done by JGroups. Can you increase the timeout
value for jnp.discoveryTimeout, to e.g. 1 ? Also, try putting a list
of at least some of your servers in PROVIDER_URL. If none are found,
only then do we use multicast discovery.

But, nevertheless ,here's the whole problem description: - I am running JBoss server as a thread in my application and one more thread is waiting for it to complete for a time period of 5 minutes.There is a ping java thread running in my system which just ping on a machine after some time interval and returns. Above scenario used to work fine in clustering mode for JBoss3.2.2RC3_Jetty4.2.11,except for "additional data" issue.All my application ears(2 in number) used to deploy successfully in the given time. Now since we needed to move to JBoss3.2.3RC1_Jetty4.2.11[JDK1.4.2],JBoss server itself fails to start itself completely. It only deploys "one" of my ear file and the other one never gets any chance.One particular observation was that ,it waits for a considerable amount of time once, it starts deploying "cluster-service" xml. I am seeing only my "ping" thread output after the "cluster-service.xml" deployment. Before "cluster-service.xml" file deployment,everything deploys as it used to do as I can see from "server.log". - Pls let me know in case of any more inputs! Thanks in advance, Nishant. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Sacha Labourey Sent: Tuesday, December 30, 2003 6:38 AM To: [EMAIL PROTECTED] Subject: RE: [JBoss-user] Clustering Problem in Jboss3.2.3Rc1_Jetty4.2.14 We need the stacktrace of the errors at least. sacha > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of > Nishant Aggarwal > Sent: mercredi, 31. décembre 2003 05:03 > To: [EMAIL PROTECTED] > Subject: [JBoss-user] Clustering Problem in Jboss3.2.3Rc1_Jetty4.2.14 > > Hi, > I have an application which used to run on JBoss3.2.2RC3_jetty4.2.11 > [JDK1.3.1_08]. > Since there was some problem in clustering[(additional data) > not coming] > with the above version,we had decided to move to > "JBoss3.2.3RC1_jetty4.2.14[JDK1.4.2]". > But in this release(3.2.3RC1),we have encountered another > problem ,due to > which my application "ears" fail to deploy completely,if the > "cluster-service" is run. > Here is the problem description: > 1.If the "cluster-service.xml" is there,then one of my application ear > deploys successfully,but other one fails. > 2.If I remove "cluster-service.xml",both of my application > ears get deployed > successfully ,no probs,like the way they used to do in Jboss3.2.2RC3. > > NOTE:I used to run the above application in "Jboss3.2.2RC3" > in cluster mode > without any "deployment" issues as mentioned above. > > Any help would be greatly appreciated! > > Thanks in advance, > Nishant. > > > > > --- > This SF.net email is sponsored by: IBM Linux Tutorials. > Become an expert in LINUX or just sharpen your skills.

RE: [JBoss-user] Clustering memory usage, can we use more agressiveGC settings?
Well, I don't have anything in mind except that there may have a "leak" somewhere in the GC of sessions. You've used tomcat or Jetty? Which http session replication implementation?

Re: [JBoss-user] Clustering memory usage, can we use more agressive GC settings?
I just realized what I said is pointless - you would have to use JGroups 2.1 or higher and I would have to make changes to the JBoss Clustering in order for you to use the new optimized flow control for JGroups. I will make these changes once I join JBoss (Oct 6th): - Update JGroups to the latest stable version - Change package names from org.javagroups to org.jgroups - Update the X-service.xml files affected (cluster-service.xml) and - Provide an example of an efficient high-throughput protocol stack for JGroups in cluster-service.xml - Plus: documentation of how to use the newer stack This will be relevant for high-throughput high load situations, but I'm not sure if this is applicable to you.

Re: [JBoss-user] Clustering memory usage, can we use more agressive GC settings?
You should try to run JGroups with the fc.xml properties: copy them from the JGroups distro, and modify you cluster-service.xml. Joao Clemente wrote: Hi! Load testing my application ( with Jboss 3.0.8 ) I had these strange results: If using 1 jboss node, with cluster settings active but without another machine, I runned a test scenario that consisted of 10, 100 and 200 users navigating through my site. I had this batch file that would do "run 10x scenario with 10 users, then run 10x scenario with 100 users, then run 10x scenario with 200 users" I left this running over night, and got the results in the next day... Then I added the second machine, with similar settings, to the cluster. I went home and left my batch test running... 50% of load to each machine. Each machine would see the load corresponding to the following batch test: "run 10x scenario with 5 users, then run 10x scenario with 50 users, then run 10x scenario with 100 users" (which would total a cluster load the same as above) Well... my test client locked soon after beginning the 50 users test... there were exceptions thrown in JBoss because of "out of memory" errors... I changed my java memeory settings by using "%JAVA%" -Xmx384m %JAVA_OPTS% in my run.bat file. I went home once again, confident that now it would work... I rerun the "10x 50users + 10x 100users" test When I got back... it was locked soon after starting the 100 users test, with exceptions on JBoss and the memory usage (measured by windows task manager) was over 400Mb... Well, I rerun the 100 users test, and it eventually locked again, exceptions and memory usage again over 400Mb after running 5x the 100 users test... While I've not reached a conclusion, these questions are bothering me: - Why did the batch rest run completely when there was only 1 machine, without exceeding the standard (128, right?) Mb memory usage? - Why do I triple the memory available to java and it still goes to maximum usage, and after hours of not loading the server the memory usage does not decrease? - Could I set more aggressive memory settings to java that could free more memory, making my app work without the "out of memory"? -- Bela Ban http://www.jgroups.org Cell: (408) 316-4459 --- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user

RE: [JBoss-user] Clustering Problem
Hello Sacha, Following is the procedure: 1.Install JBoss3.2.2RC1 in "/user/sacha/Jboss3.2.2" and another instance in "/user/sacha/server2/Jboss3.2.2" dir. 2. a)First,Start server 1(/user/sacha/Jboss3.2.2) jboss instance on one Solaris machine and b)After server 1 comes up,start server 2 jboss instance(/user/sacha/server2/Jboss3.2.2) on some other Solaris machine on the same NFS system.The jboss server deploy mode is "all". 3.Now,put the jar(Hello.jar) attached under server 1 "all/farm" directory.Server 2 picks it up and it deploys in server 2 "all/farm" dir also. 4.Delete the Hello.jar from "all/farm" dir of server 1.It is successfully undeployed from server 1 and server 2. 5.Now,put the same jar in "server 2".Only server 2 deploys it.Server 1(which was brought up first) doesn't get any notification of this and its oblivious of this deployment. I am attaching the sample jar I used for my testing! HTH, Nishant. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Sacha Labourey Sent: Sunday, July 27, 2003 11:16 PM To: [EMAIL PROTECTED] Subject: RE: [JBoss-user] Clustering Problem If you have a small example and procedure (starting from a raw JBoss installation) that consistently fails, please send it to me.

RE: [JBoss-user] Clustering Problem
Hi Kevin, Thanks for the info! I don't know if 3.2.2RC2 will sort out this issue.Becaz,the problem seems to be with "order" in which the servers in cluster were started. As asked by you,I had put the jar in server 2 after removing the jar from one of the servers.Thus undeploying it before deploying it! Any help would be appreciated!

Did you put it in node 2 when both were clean? Re-deploying of apps in the /farm dir doesn't seem to work in RC1. You may want to get the very latest RC2 that just came out two days or so ago.

RE: [JBoss-user] Clustering grins and woes
Sorry, I always forget that. 3.2.2RC1. We are not seeing this work. I see the nodes show up and talking to each other, I just don't see the app being deployed (when starting up a new clean node) from an already running node. I also don't see re-deployment farming working at all. At least the several times I have tried it. --- Bill Burke <[EMAIL PROTECTED]> wrote: > What version of JBoss?

Re: [JBoss-user] Clustering broken in 3.0.6 again ?!?
Thanks for your reply. I'll do it today. In the meanwhile I've tried with a older version (3.0.5RC2) and I've got the same behaviour... altought I had it working before (back in December). I did had one change in my network: I now use DHCP to get my machine addresses, when before I had it with fixed addresses... Maybe the dhcp settings are blocking multicast? That would explain it..

Re: [JBoss-user] Clustering broken in 3.0.6 again ?!?
Have you read the JavaGroups doc and got e.g. the Draw demo working ? - do you know that you have multicast routed correctly between the nodes of your cluster ? If not, then no amount of tinkering with Jetty config is going to get this going. I haven't made any such changes to Jetty... maybe JavaGroups has changed ? Works for me ! Jules [EMAIL PROTECTED] wrote: I am trying http clustering with jboss 3.0.6 (jetty) [After seeing some bugs related to JavaGroups getting fixed in cvs before 3.0.6 being release I tought this "stable" would be ok too] I just got 3 similar linux machines (2 with RedHat, 1 with Debian), all using j2sdk1.4.1_01 and Jboss 3.0.6.

RE: [JBoss-user] Clustering and MBean Failover Question
Hello, Nothing in the pipe.

RE: [JBoss-user] Clustering and MBean Failover Question
This sounds like an interesting solution. A question, though: Are there any plans to implement a way to define an mbean as being in a master/slave configuration from a -service.xml descriptor? Not that I'm asking you to implement it, but wanted to see if this is something the JBoss team has had requests for in the past and may be planning to implement. One of your "foes" supports mbeans at a domain level rather than a server level when in a clustered situtation (actual implemention success is unknown at this time, but the docs say so), so I was thinking something similar would be a nice jboss-specific feature as well. Also, does any part of Jboss use this approach already, or all deployed services assumed to be needed on all cluster nodes?

RE: [JBoss-user] Clustering and MBean Failover Question
why not create a second mbean, which would be jboss specific, doing all the clustering registration. When it detects it is the master, it simply send a JMX notification (or any invocation) to the non-jboss specific MBean saying "You are the master". If you then need to port this to another environment, you have one safe mbean and one non-portable mbean: at least they are split. You can do that with any helper class aswell, it doesn't need to be an mbean > -Message d'origine- > De : [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]De la part de McKnight, > David > Envoyé : jeudi, 3 octobre 2002 17:31 > À : '[EMAIL PROTECTED]' > Objet : RE: [JBoss-user] Clustering and MBean Failover Question > > > Sacha, > > First off, thanks to you, Marc, Scott, and everyone else there for such a > cool product.

RE: [JBoss-user] Clustering and MBean Failover Question
Yes, take a look at the Distributed Replicant Manager (DRM) on top of the partition. Take a look at the very recent api change. You simply register your mbean under a given name in this service, and register for composition change (always in the DRM). Inside the event handler, you call somthing like DRM.iAmTheMasterNode which will return a boolean. If true, you are the master of the cluster, if not, you are a slave. Your mbean doesn't need to be started on all nodes of the cluster: the DRM can work with subset of a cluster.

Re: [JBoss-user] Clustering: Possible to use a "backplane" to connect the servers??
but at all, mind the gap!
... if you are the generating pk with your ejb's for example in a
PrimaryKeyGenerator and not database based like through triggers or
'autoincrement' and the clustering fails on one interface, but all nodes
are still alive ...

(Could you explain me your topology first? how you use it? That's
interesting. )
First, it depends on your switch. If it has enough processing power and a
good backplane, you don't need a second set of interfaces. In this case, you
must either configure your switch to not forward multicast (of a particular
port) from one side to the other => you need a switch working a the OSI
layer 4 (=> a router) or you need to change the JavaGroups properties to use
TCP instead of multicast. Only membership discovery paquets will then travel
from one side to the other => low traffic.
If you have a "slow switch" (or a very big inter-node communication), it
will certainly help to split the load yes.

Sacha

Re: [JBoss-user] clustering question
I know this is OT, but the thread reminded me of this... Has anyone looked at using something like "JSR-107: JCACHE - Java Temporary Caching API" to help in keeping cached entity beans in a cluster synchronized instead of relying solely on the database?

Distributed cache is one way, but you already knew that :) Cheers, Sacha ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
RE: [JBoss-user] clustering question
Hello Dennis, For now, for entity beans, we use pessimistic locking at the database level i.e. we use the ~"SELECT ... FOR UPDATE" features of databases to lock database rows. Consequently, you need to run in commit option C (or B if you have a kid whose name starts with a B... it won't make a huge difference.) Now, if you use commit option A, it means that you have read-only beans. In this case, it makes perfect sense. Then, if you want caching + commit option C, then you will either have to: 1°) wait on a future release of JBoss that may have distributed cache (nothing planed) 2°) use one of JBoss' partners distributed cache (see the partner page on JBoss web site) Anyway, read the clustering doco, you will understand all this very easily ;) Cheers, Sacha > Let's say I cluster two jboss servers and I have an Entity Bean with > commit option A. > > Are the attributes of the Entity Bean clustered? ie: user on server 1 > calls a set Method, then user on server 2 calls the get method for that > attribute.

Re: [JBoss-user] clustering question
I don't see a response yet from the experts...so I will jump in. Don't use commit option A with clustering, and do use whatever your database supplies for select for update. The clustering implemention relies on database locking to synchronize the different copies of entities. I actually don't know of any other way to get consistency, but would be interested in finding out if there are other ways. david jencks On 2002.04.29 17:14:51 -0400 Dennis Muhlestein wrote: > Let's say I cluster two jboss servers and I have an Entity Bean with > commit option A. > > Are the attributes of the Entity Bean clustered? ie: user on server 1 > calls a set Method, then user on server 2 calls the get method for that > attribute.

RE: [JBoss-user] Clustering (failover) works but not RoundRobin load-balancing policy
Hello Michel, I've just made some test yesterday with the latest CVS version (plus fixed a bug). Can you please try the CVS HEAD and if it doesn't work, send me your code. Thank you.

RE: [JBoss-user] Clustering with JBoss
Hello, A first test release of HA features for JBoss is available from here: http://194.38.95.241/jboss/ It provides only HA features for Stateless Session Beans and should be included in Jboss 3.0. I will shortly (I do not have much time these days) post a written proposal for the next version of HA. Anyway, depending on what you want to achieve, you can already built some "cluster" of JBoss servers. Check the archives for some recent posts describing such configurations.

RE: [JBoss-user] Clustering
Hello Gajendra, You will find Stacy's work directly in the CVS tree (or last source daily snapshot available from JBoss web site). As for the HA features for SLSB, you will get everything needed here : http://194.38.95.241/jboss/ Feedback is welcome!
