JMX in clustering

          hi all,
          i was wondering one thing. When u deploy a web application, BEA's MBeans allows
          you to change values in the web.xml descript or files. i have changed some values
          thru the console, and i have noticed that if the change is done meanwhile the
          user is logged in, the user's ession will be invalidated and hte user has to re-login.
          What happens in a clustered environment? is it so that the session will be invalidated
          for all the servers in the cluster?
          What happens if, using the plain old approachinstead of JMX, i shut down the servers
          part of the clusters one at a time meanwhile the user is logged in? will hte user
          lose its Session also in this case?
          regards
          marco

My reference for Websphere 5.1 is the "IBM WebSphere Application Server V5.1 System Management and Configuration" redbook, number SG24-6195-01. It has a section about page 780 and onwards about JMX, in the context of administration and scripting.
Presumably there's a similar reference for WS 5.0.

Behaviour of JMX in clustering

          hi all,
          i want to write my Custom MBean to monitor some part of my web applications
          (such as logging variables), and i wanted to know what is the behaviour of JMX
          in a cluster.
          Suppose that i write my CustomMBean to monitor properties of some components of
          my webapplication.
          If i use my MBean to change the properties of one component, will the change
          affec all teh cluster if teh webapp is deployed in the cluster?
          thanx in advance and regards
          marco


Thanks for your response Patrick.
Your suggestion should work too but I am curious as to why 'NOT IN' is not working now.
As I mentioned earlier that '<>' or NOT EXIST can work, but if I have to make this change then I
would have to do it in the entire codebase; just to be sure that I do not encounter this issue again.

JMX in clustered environment

          hi all,
          i am little confused about how weblogic 'behaves' in following situation:
          - i have one adminserver and 4 managed servers in a clustered environment
          - i deploy an application on all the servers in the cluster
          the application (servlet based) registers an MBean with adminserver.
          question that i would like to ask is the following:
          if my app is deployed in a cluster with 4 servers,does it mean that i will have
          at least 4
          registrations of the same MBean? because in this case i'¨ll have to handle exceptions
          in case same objectname has been registered.
          can anyone clarify me?
          thanx in advance and regards
          marco


Is your configuration any different in the clustered environment? Are you using cache-coordination/synchronization in TopLink?
Any idea of what the application is doing that leads to the server running out of memory?
You may wish to use a memory profiler such as JProfiler or JProbe on the server to determine the cause of the memory leak.

Can single JMX manage two clusters

Hi
Just want to check that is that possible to manage 2 cluster on same machine with one JMX node..
Thanks,
Gaurav

No. The management/jmx mode is a member of the cluster, as such it can't be a member of another cluster.

Q: Hidden clustered jmx execute functionality?

Hello,
In my dev environment I have a cluster of two servers plus a node manager.
I have deployed an ear to the cluster using the console. The ear has a
servlet that registers an MBean.
The interesting thing is that with a third party MC4j JMX utility I can
execute a JMX method on serverA and somehow WebLogic 8.1SP3 replicates
calling this method on serverB.
I can verify this because MC4J shows an attribute has changed on serverB but
I never called the JMX method on serverB.
I've Google'd and read the WLS docs and haven't found this described so I'm
not sure what the limitations are.
Any pointers to documentation or comments on this behaviour would be most
welcome. It seems too good to be true, and I'm likely missing something if
I can't find documentation about such a powerful feature.
Cheers.

Hello Mark,
It indeed seems too good to be true. Perhaps its a bug, or shall I call it a feature :-).
I will try to reproduce this on my environment and see if I can reproduce.
Thanks,

Failed to Deploy Workflow on Clustered SOA

Hi,
We have developed a custom workflow which is working fine in the test environment which is a non clustered environment. However, now when we are deploying the same workflow on live SOA environment which is clustered, we are getting the error below. Can anyone guide how to fix this or identify which class path variables are creating problems. Does this have to do anything with clustering or not?

Error in accessing Processes in a Clustered WLS Environment

Hi all,
We are running a clustered deployment of OBPM in WLS. The cluster is behaving properly execpt published and deployed projects are displaying the following error when accessing the workspace:
The Process '/FooRequestProcess#Default-1.0' is not available.
The Process '/FooCenterRequestProcess#Default-1.0' is not available. Caused by: Process '/FooRequestProcess#Default-1.0' not available. Caused by: Cannot reach engine 'bpmQAengine' at URL: ''. Caused by: While trying to lookup 'engines.bpmQAengine' didn't find subcontext 'engines'. Resolved ''
Now, there was an issue with the JDBC Data Source in WLS which has since been fixed otherwise neither the engine or workspace would have come up. I have rebuilt and redeployed the engine, and I have undeployed and unplished the project then republished and redeployed it yet I still see this error.
The XA definitions are correct. Does anyone have a clue as to the cause of this?
TIA,
IGS

Am getting the same error

Am not sure of this error... Please advice how to recitfy.. I have given the host and port correctly (pointed to one of the managed server)
The most interesting part is I have configured cluster in distributed environment. I have deployed the project to a cluster with two managed servers. one managed server is configured to another physical server..
When i try the workspace with server1:9001\workspace am able to see the deployed processes without any errors/exceptions
but when i try the workspace with server2:9002\workspace am getting process unavailable error..
server1:9001 -- managed server1 of the cluster to which the process is deployed
server2:9002 - managed server2 of the cluster to which the process is deployed
Kindly help
Thanks,

BlazeDS clustering with JBoss AS

Greetings,
I'm currently working on a system that uses Adobe Flex 3 and BlazeDS. It works fine in the actual TomCat standalone server, but we got plans to upgrade our infrastructure to a cluster environment running JBoss AS.
I got really concern when I begin to read many articles and forum posts about BlazeDS issues with clustering.
Is this a risk to my project ? Should I quit using BlazeDS ?
Thanks is advance,
Daniel Cheida

Hi Mauricio,
I installed OCMS in JBOSS AS 4.0.5.GA installation mode.I m facing the same problem on ocms startup, i.e., proxyregistrar war file is not deployed properly. OCMS not working properly with JBOSS AS 4.2.1 GA and JBOSS AS 4.2.2 GA too i.e., OCMS MBeans are not shown in the jmx-console page and the oc is not getting connected to the ocms, traffic.log file shows that application proxyregistrar is not found. Please help me out in solving this issue.
Regards,
Harini Dhanasekaran.

Specifications of deployment and lifecycle of JMX beans in a JEE server

Hello,
one colleague of mine is developping a service that uses an MBean to mimick a singleton (the MBean is not used for instrumentation or administration, it just holds a pool of shared non-standard resources) within a Glassfish server.
I fought this idea (as I found a static utility would be both straightforward and easy to implement), but I took it, from this forum in particular, that it is a recommended way to use an MBean to serve as a shared resource holder. Point taken (I'm not concerned with clustering yet, I mean it's OK if the singleton is not cluster-wide)
The problem is, my colleague warns that he witnesses "strange deployment behavior" with regard to the MBEan: in particular, it seems that the MBean is not unregistered upon EAR undeployment, and not redeployed upon EAR re-deployment. In particular updates to the MBean code (currently packaged within the EAR) require a server restart to take effect.
From what I understand, the MBean is registered in a JVM-wide registry (the MBean server), and its classs and instances have a different lifecycle from the EAR, which has (some sort of, obviously more complex in the details) class-loader scope.
I admit I'm making that up, from various observation -> my main problem is that I can't find an appserver-agnostic specification of the MBean lifecycle in a JEE environement. The EJB3 specification do not mention JMX (but as I understand it EJB3 alters none of the way JMX works).
There seems however to be a J2EE-specific way of handling MBean - presumably because the hot-deployment-without-JVM-restart expands the MBean lifecycle beyond the EAR lifecycle.
Could you point me to authoritative references on JMX used in JEE servers. In particular specification of the lifecycle and deployment is extremely welcome.
I'm sorry for asking pointers: my own web searches turn up non-specifying docs.
And if I search on JMX and Glassfish together, I find articles on either:
- how Glassfish uses JMX to implement a lot of stuff, but not how Glassfish implements "JMX lifecycle" (if that expression even means something).
- how to extend Glassfish's adminsitration capabilites writing custom MBeans
Thanks in advance,
J.

The location of the registration code is thus the key to all this. e.g If you register manually in some startup class, you can unload/load the required versions of the MBean code.That's what we do (using a RegistryServlet and init()/destroy() callbacks).
Sketchy description from what I understand of the developer's code: the init() indeed looks up the MBean and unregisters it if it exists, then registers it anew. Sometimes, the unregistering will fail (I haven't witnessed that), which triggered this topic.
We have to investigate it further (with more rigorous archiving and analysis of the error logs). I'll post updates if any.
If the MBeans are configured to be registered by the server itself (common) then the server would need to be restarted for the changes to be picked.OK. I have no idea how to configure where the MBeans are registered, time now to confess I have used JMX only in trivial cases so far.
It is my sincere hope that you won't need to use the techniques of chapter 8 of [this specification|http://java.sun.com/javase/6/docs/technotes/guides/jmx/JMX_1_4_specification.pdf] .
Indeed!
Probably my lack of JMX knowledge, but I have no idea what the "Mlet service" is in my scenario, and I suspect I won't want to know :o)
Overall this suggests that using JMX introduces unforeseen complexities, that may be overkill in our scenario (but I'm biased as I defended a couple of other alternatives).
Thanks for your help so far; I'm still looking for some document that would clarify how the JEE server, or how Glassfish specifically, handles MBean lifecycle.

How to get node's JMX port?

How to get assigned node's JMX agent port from admin node in weblogic 9.2.2 clustered env?

1 Get an mbeanserverconnection
* http://e-docs.bea.com/wls/docs92/jmx/accessWLS.html
2 Use this connection to lookup the listen port:
ObjectName service = new ObjectName("com.bea:Name=RuntimeService,Type=weblogic.management.mbeanservers.runtime.RuntimeServiceMBean");
ObjectName serverConfiguration = (ObjectName) connection.getAttribute(service, "ServerConfiguration");
int port = Integer.parseInt(connection.getAttribute(serverConfiguration,"ListenPort").toString());
I hope this helps

Undeployment of component [testJMS] failed. Application testJMS is referenced by server and must be referenced by no server instances or clusters.
can anyone help me???

Hi,
Looks like all three questions posted by you are related to this error:
Undeployment of component [testJMS] failed. Application testJMS is referenced by server and must be referenced by no server instances or clusters.
This error message indicates your application is still referenced by other server instances and therefore could not be undeployed.
Have you deployed your application to multiple server instances and use asadmin undeploy command to undeploy from one server instance?
When an application is deployed/referenced on multiple server instances, and you want to remove one reference from a particular server instance, you cannot use "asadmin undeploy --target [server_instance] foo", you have to use the "asadmin delete-application-ref --target [server_instance] foo".

java.lang.NoSuchMethodError: org.apache.naming.resources.ProxyDirContext.lookupCache(Ljava/lang/String;)Lorg/apache/naming/resources/CacheEntry; org.apache.catalina.servlets.DefaultServlet.serveResource(DefaultServlet.java:663)
Looks to me like you're running with a mix-n-match version of classes. The serveResource method is expecting that you have the correct version of the org.apache.naming.resources.ProxyDirContext class which has that lookupCache method with that signature, but it is not there. I don't know how to tell you to fix your installation, but it is goofed up.
