Hello,
Could you get any answers for this apart from the forum? I face the same situation on a non-clustered WebSphere server. We have a case open but no solution yet...
The error message is as follows:

No communication between the two nodes in weblogic cluster

Hi All,
We have installed weblogic cluster in our environment(LINUX 64-Redhat.5).On one node admin server ,managed server1,on second node we have managed server2.When we try to deploy application on one node it is not getting reflected in othe node.We have ran datagram test to check communication between 2 node.
Here we observed that listener and pulisher are picking wrong IPs not the server Ips.
can any one explain why and what is the problem.
thanks,
sudheer.

Hi Sudheer,
While performing the datagram test you mention the ports and ip so I am not sure how they are picking wrong ip and port. Follow the instructions to perform the test http://coherence.oracle.com/display/COH35UG/Performing+a+Datagram+Test+for+Network+Performance
Re the deployments, you need to ensure that multicast is enabled in your environment and both your managed server are in the same subnet otherwise you need to specify WKA for unicast communication. I am assuming that you are building SOA infrastructure as it internally uses Coherence for deploying applications and you can follow the instructions http://download.oracle.com/docs/cd/E15523_01/core.1111/e12036/extend_soa.htm#CHDEAFJH else use the intructions as mentioned here http://download.oracle.com/docs/cd/E17904_01/web.1111/e13709/features.htm
Hope this helps!

HowTo:Publish Msg to JMS queue deployed in a Weblogic Cluster from a client

Hello All-
I am new to Weblogic and need help from this forum. Forgive me for my ignorance. I am learning.
Below is a brief about the context and the issues that we are facing:
Background
=======
1. We have Oracle Service Bus (OSB) installed on top of Oracle Weblogic Server (ver 10.3). In OSB we have developed a proxy service that listens to a JMS queue for an incoming message
2. The Weblogic environment is a cluster having 2 managed servers listening to different ports and it is front-ended by a Apache Load Balancer.
3. Our requirement is to post an XML message from a Java client to the JMS queue which will then initiate the proxy service deployed. We are using t3 protocol to post the message from the client to the JMS queue
Issue
====
1. To post an XML message from the client, how do we give the address of the JMS queue in the clustered environment to enable failover/loadbalancing if one managed server goes down. I understand from your earlier posts in this forum that directly hitting the JMS queue on a particular managed server will not enable failover/loadbalancing in case one of them goes down
2. Do we need to modify any config file in the Apache Proxy Plugin?
3. Do we need to provide the address of the Apache proxy in the client to send the message?
Kindly clarify and let me know me know if you need any additional information.
Greatly appreciate your help!!!
Regards,
Dibya

Web Proxying to a WebLogic Cluster using the HTTPS protocol

Hi all,
I am recently involved into JWS proxying to WebLogic Cluster.
I don't have any technical problems at the moment but "conceptual" problems, that is:
- my jws proxy server should connect to a WebLogic Cluster through a Bea plugin configured wish SSL parameters;
- my jws proxy server should pass the incoming request using a load-balancing algorithm among the two nodes of the cluster, that are actually installed on two different machines;
- the jws proxy server doesn't seem to accept multiple certificates.
My question is: how can I configure my proxy plugin to route the incoming requests to my WebLogic Cluster using the https protocol? As a matter of fact, each certificate should be hostname dependent, and it looks like that the proxy plugin doesn't accept a multiple certificate configuration (and it should actually match the CN entry in the certificates with the actual hostnames of the nodes).
Any hint?
Thx a lot,
Luca

It is supported in 5.2

ADF Application error when deploy on WebLogic Cluster

Hello,
I setup a WebLogic 10.3.5 Cluster, but I have problems to deploy my ADF application (ADF 11.1.2).
I am getting the following java.lang.NoClassDefFoundError: oracle/adf/share/logging/ADFLogger
The problem does not occur if I deploy the same application only to the AdminServer.
In order to setup my WebLogic Cluster I followed the process described by Mark Nelson at http://redstack.wordpress.com/2010/12/20/using-weblogic-as-a-load-balancer/
Any idea?
Thanks,
Cristo A.

Have you installed the Oracle JRF template to the managed servers?
The error indicates that you didn't install the adf runtime (JRF template) for your jdev version onto the managed servers.

AD Connector Error on Weblogic Cluster

hia all,
I have clustered deployment of oim 11g(11.1.1.5) in four node weblogic cluster 10.3.5
While installing ADConnector 9.1.1.7.0 (copied on all 4 nodes at same location) we got following error
DOBJ.EVT_INTERNAL_ERROR
Adapter Compilation Failure Bulk Exception
and in description it says (for the third task)
X Compilation of Adapter Definitions >(Failed)
Is there any way to have it fixed? do we need to set the XL.compilerPath uptill the the \bin of the jrockit? (it is not getting unset / blank once its set, compulsory value). I have also set the limits.config settings in linux to max, since I get "Too many files open" error in the OIM diagnostic log. following is the log

any comments?

Ok ... i have resolved the issue, the problem was traced back to the change of access permissions in the Linux. the weblogic "nodemanager" was being started as root user this was changing the permissions on the folders and files in the /home/oracle. so I changed the startup of nodemanager from root to oracle and with some other changes the objective was achieved..... :)

Help on Coherence + Weblogic Cluster configuration

Hi,
I am new to Coherence. I am exploring coherence to fulfill one of my requirement.
My requirement : I have an application deployed on a Web logic Server clustered environment. I need to cache the application specific data(java maps) and that should be available for all nodes of the WLS cluster. The application data that's being cached, can be updated from any of the node from the WLS cluster and updated application data from the cache should be available for all the nodes of the WLS cluster. The nodes in the WLS cluster resides in different machines from different locations.
Can I use coherence as a caching services for my requirement?
If Yes, do I need to start a coherence cache server on each node of the WLS cluster?
If yes, do I need to specially configure these cache servers, so that these cache servers would communicate each other in case of any data updates in the cache?
It will be great help if you could also provide sample configurations to achieve the above scenarios.
Thanks in advance!
regards,
Srinivas M

You can start one cache server in the network by using for example
# home directory
BEA_HOME="/home/oracle/bea"
export BEA_HOME
# java vendor (for example Oracle or Sun)
JAVA_VENDOR="Oracle"
export JAVA_VENDOR
# cache server klasse
CACHE_SERVER_CLASS="com.tangosol.net.DefaultCacheServer"
export CACHE_SERVER_CLASS
# coherence options
COHERENCE_OPTIONS="-Dtangosol.coherence.management=all"
export COHERENCE_OPTIONS

${JAVA_HOME}/bin/java ${MEM_ARGS} ${COHERENCE_OPTIONS} ${CACHE_SERVER_CLASS}The -Dtangosol.coherence.management=all option gives you some handy information on what the cache is doing by using for example the mbean browser provided by jconsole or jrockit mission control.
You can create an application in which you create a cache, the following shows an example of a servlet
import com.tangosol.net.CacheFactory;
import com.tangosol.net.NamedCache;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.Random;
public class TestServlet extends HttpServlet {
 private NamedCache movies;
 public void init() throws ServletException {
 movies = CacheFactory.getCache("repl-movies");
 movies.put(10, new Movie(10, "Rear Window", "Alfred Hitchcock"));
 movies.put(20, new Movie(20, "Vertigo", "Alfred Hitchcock"));
 movies.put(30, new Movie(30, "Double Indemnity", "Billy Wilder"));
 movies.put(40, new Movie(40, "Touch of Evil", "Orson Welles"));
 protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
 Integer[] integers = {10, 20, 30, 40};
 Random random = new Random();
 while (true) {
 movies.get(integers[random.nextInt(4)]);
}Package the servlet into for example a WAR file and deploy it to a configured WebLogic cluster.
By accessing servlet on the different nodes of the cluster a new cache gets created and added to the
already running DefaultServer.
The hard part is to configure your cache. As you can see in the servlet init we ue something like CacheFactory.getCache("repl-movies");
Coherence default with some example cache configurations which are contained in the coherence.jar (coherence-cache-config.xml).
The following entry is used
<cache-mapping>
 <cache-name>repl-*</cache-name>
 <scheme-name>example-replicated</scheme-name>
</cache-mapping>
<replicated-scheme>
 <scheme-name>example-replicated</scheme-name>
 <service-name>ReplicatedCache</service-name>
 <backing-map-scheme>
 <local-scheme>
 <scheme-ref>unlimited-backing-map</scheme-ref>
 </local-scheme>
 </backing-map-scheme>
 <autostart>true</autostart>
</replicated-scheme>A replicated cache is probably what you need as well. As you want all the data to be available on all nodes. If you want to use
your own cache configuration you can add the option -Dtangosol.coherence.cacheconfig (see the start script for the default server)

How to setup weblogic cluster in 6.1 SP4

          Hi All,
          I have a Licensed weblogic in my solaris servers. I need to test weblogic clustering
          . How can i simulate weblogic clustering is there is any easy steps to do that
          and what should i do in order to make my EJB`s cluster aware. And some ppl say
          that i need to take a seperate weblogic cluster license other than the weblogic
          license.Kindly help me in proceeding further
          Thanks in advance
          Bala.J

Having issue with start weblogic cluster with tangosol cluster

Hi,
Oracle Coherence Version 3.3.1/389p1
Grid Edition: Development mode
We are using Weblogic 8.1.5 with Tangosol 3.3.1 on Linux servers.
And we added the initializing logic in the servlet's init() method to get all NamedCaches and put into the ServletContext.
When we start weblogic cluster, the first weblogic member will startup successfully with following messages :

Hi, Gene
Thank you for the response. I will send you our full log files and thread dumps.
I just want to give you more details about our cases :
1. This only happened without starting cache servers (com.tangosol.net.DefaultCacheServer).
2. And our application which are running on weblogic cluster will just call "CacheFactory.getCache("XXX")", and running as the Tangosol DataClient.
3. All weblogic member servers will be up running successfully if our cache servers are up running.
Also I tried to test another case :
Suppose all weblogic instances and cache server instances are up running. Now I trying to restart (kill weblogic instance process and restart) one of the weblogic member, It will up running successfully only if add some sleep times after killing weblogic processes and restarting it. Looks like tangosol cluster need certain time to aware the member has left cluster, then the restart process will be successful.
Questions :
1. Should we start our weblogic cluster only after cache server cluster is up running ?
2. How do we decide how many time we should wait before start new process to join the cache cluster ?
Could you please help to explain this one for me and let us if there anyway we can do to avoid the problem.
Many Thanks !!!

Timesten database driver is not supported in Weblogic cluster mode??

Does anybody encounter this situation??
I have 2 managed server in a Weblogic cluster domain and there is DataSource for them.
In each managed server, I setup Timesten client correctly to connect to Timesten Oracle DB cache server.
But when we start each of managed server, I will get exception:

Single sign-on in weblogic cluster?

 I am using wls 7.0 sp1 that form a cluster by two managed servers each at different
 physical machine.
 In front of the servers, a hardware load-balancer providing a virtual ip that
 mapped to the real ip of the 2 machines.
 I deployed a web application to the cluster. The html & jsp files are all protected
 by Form Based Authorization.
 My expectation is, whenever I sign-on to the first managed server, the login credential
 should also be valid for the second managed server.
 But it is not the case.
 My situation is:
 - open brower with url: http://virtual.ip:7001/admin.jsp
 - the load balancer map the request to my first managed server.
 - the response from the first managed server prompt the login page for username
 and password.
 - after POST the information, my target admin.jsp page display properly.
 - when I click the link within the admin.jsp page, eg. http://virtual.address:7001/status.jsp
 there is two possibilities:
 1. the load balancer route the request to the first managed server and everything
 well.
 or
 2. the load balancer route the request to the second managed server and response
 with login page again.
 The second case is definitely not what I expected.
 Question:
 Is it the default behavior of Weblogic cluster on the single sign-on? I think
 my login is against a WLS domain (at least a cluster), not to a specific web server!
 Any comments are welcome.


 Note my answer is not directly related to your question, but it might help.
 From my experience to configure WL cluster with hardware load balancer, the session
 stick (layer 7 switch) should be used (either using the session cookie, or ServerID
 cookie). That is, unless one instance is down, all requests from the same session
 are better go to the same server. I ever tried round-robin or random load balance
 policy at hardware load balancer without session stick, and the result was as
 disappointing as you have seen.

Patchset3 (11.1.1.4/wls 10.3.4) Remote debugging JDPA in weblogic cluster

Hi,
I am using Patchset3 (JDeveloper 11.1.1.4/ weblogic server 10.3.4). I was wondering how i can remote debug with
a) weblogic managed server that is part of a weblogic cluster
b) the cluster itself that contains multiple managed servers.
Note that i do understand how to remote debug against a weblogic server (e.g. http://jdeveloperfaq.blogspot.com/2009/12/faq-4-how-to-remote-debug-adf.html), but have not been able to find out how i can achieve this against a cluster that has multiple managed servers. Any directions will be appreciated.
Thanks,

Hi,
haven't tried it but here are some suggestions that might be of help:
1) Each managed server for each cluster node should be setup for remote debugging. This means that each managed server must be started with the -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=4000,server=y,suspend=n* options in the WebLogic start-up script. Also Tunneling must be enabled for each managed server for each cluster node.
2) Make sure that you specify a different connection port for each managed server. This is indicated by the address* specifier above.
3) It seems logical to me that you will need to start separate instances of JDeveloper - one for each managed server that you need to attach to.
Let us know how it turns out,
Nick

Caching read-only data in a weblogic cluster: Need Help

Hello,
I'm working on the development of a web site that will be based on a weblogic cluster spread across several weblogic instances running on several unix boxes.
To avoid frequent hits to the database, I would like hold a huge amount of data in the application's in-memory cache. The idea is to query the database at startup and store the results in memory for the life of the JVM.
I have three questions around this:
1. Is it advisable to store this data in the form of read-only entity beans?
2. If not, what other options do I have?
3. In some rare cases, a back-end script might change (and commit) data contained in one or two of these 64000 records. What is the best way of propagating these data changes across the cluster?
Any help in this regard would be greatly appreciated.
Regards,
Dipak Jha

Could somebody please guide me on this?

Apache Proxy Plugin with SSL in Weblogic Cluster

Hi,
I have configured a weblogic cluster and configured SSL. Then I configured the apache plugin to work with the cluster machines with non ssl and worked succesfull but when I configured the ssl communication between apache and weblogic I´m having problems.
The actual configuration is:
<Location /spmlws>
SetHandler weblogic-handler
WLLogFile /var/log/httpd/tmpweblogic1.log
DebugConfigInfo ON
Debug ALL
KeepAliveEnabled ON
KeepAliveSecs 15
WebLogicPort 7002
SecureProxy ON
TrustedCAFile /opt/freeware/etc/httpd/conf/trustedCA35cert.pem
TrustedCAFile /opt/freeware/etc/httpd/conf/trustedCA36cert.pem
WLProxySSL ON
RequireSSLHostMatch false
WebLogicCluster machine35:7002,machine36:7002
EnforceBasicConstraints false
</Location>
The problem is that the plugin always takes the last TrustedCAFile. In this way if machine36 is down the plugin tries to send all the request to machine35 but it takes the TrustedCAFile for the machine36 (/opt/freeware/etc/httpd/conf/trustedCA36cert.pem) hence the apache complains
[Wed Jun 30 11:13:56 2010] [error] [client 10.19.232.249] ap_proxy: trying GET /spmlws/OIMProvisioning at backend host '10.19.232.97/7002; got exception 'WRITE_ERROR_TO_SERVER [os error=0, line 796 of ../nsapi/URL.cpp]: '
What can I do to have multiple TrustedCAFile or to have working the communication between apache and weblogic cluster using SSL?
thanks in advance

Acording to the documentation this is not possible.
One way to achieve the load balancing of n-weblogic servers in cluster using ssl is to configure de HttpClusterServlet.
