Configure Weblogic Cluster.

Hi All,
I am new to this clustered envrionment.. It would be great if you can give me few pointers, how to configure a cluster on weblogic 8.1.
thanks

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
COHERENCE_OPTIONS="${COHERENCE_OPTIONS} -Dtangosol.coherence.management.remote=true"
#COHERENCE_OPTIONS="${COHERENCE_OPTIONS} -Dtangosol.coherence.cacheconfig=WEB-INF/classes/session-cache-config.xml"
#COHERENCE_OPTIONS="${COHERENCE_OPTIONS} -Dtangosol.coherence.session.localstorage=true"
WL_HOME="${BEA_HOME}/wlserver_10.3"
export WL_HOME
BEA_JAVA_HOME="${BEA_HOME}/jrockit_160_05_R27.6.2-20"
export BEA_JAVA_HOME
SUN_JAVA_HOME="${BEA_HOME}/jdk160_11"
export SUN_JAVA_HOME
if [ "${JAVA_VENDOR}" = "Oracle" ]; then
 JAVA_HOME="${BEA_JAVA_HOME}"
 export JAVA_HOME
 MEM_ARGS="-jrockit -Xms512m -Xmx512m -Xss128k -Xgcprio:throughput"
 export MEM_ARGS
fi
if [ "${JAVA_VENDOR}" = "Sun" ]; then
 JAVA_HOME="${SUN_JAVA_HOME}"
 export JAVA_HOME
 MEM_ARGS="-server -Xmx512m -Xms512m -Xmn256m -Xss128k -XX:PermSize=128m -XX:MaxPermSize=128m -XX:+UseParallelGC -XX:ParallelGCThreads=2 -XX:+UseParallelOldGC -XX:+AggressiveOpts -XX:+UseBiasedLocking"
 export MEM_ARGS
fi
# classpath for the cache server
CLASSPATH="${WL_HOME}/coherence/coherence.jar"
export CLASSPATH
# start the cache server
${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)

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 :

Could you please explain why it happens, and what should I do to resolve this issues ?
Many Thanks,

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 !!!

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.

About weblogic proxy call weblogic cluster's servlet error

 I use weblogic server 5.1, configruation tow weblogic cluster server and a weblogic
 web server, through weblogic web server received browser's http request only,

 it's ok.

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.

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:

Timesten database driver is not supported in Weblogic Cluster mode domain??

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:

Hi,
I have use WebLogic Server Console, tree: Services -> JDBC -> Connection Pools. Then I have choose 'Configure a new JDBC Connection Pool...':
1.) as 'Database Type:' I have select MySQL (version using com.mysql.jdbc.Driver) -> click 'Continue' button;
2.) 'Database Name:' = OSS; 'Host Name' = localhost; 'Port' = 3306; 'Database User Name:' = root; -> click 'Continue' button;
3.) 'Driver Classname:' = com.mysql.jdbc.Driver; 'URL:' = jdbc:mysql://localhost:3306/OSS; 'Database User Name:' = root; 'Properties:' = user=root -> click to 'Test Driver Configuration' button.
After click on test driver button I get message: JDBC driver is not on the CLASSPATH.
But when I check System variables (in Control Panel -> System) I have set up following:
CLASSPATH=.;C:\DB2\java\db2java.zip;C:\DB2\java\db2jcc.jar;C:\DB2\java\sqlj.zip;C:\DB2\java\db2jcc_license_cu.jar;C:\DB2\bin;C:\DB2\java\common.jar;C:\DBS\JDBC\db2\db2.jar;C:\DB2\BIN;c:\mysql.jar
The last value is 'c:\mysql.jar' and that's the mysql jdbc driver located on c:\.
I don't understand why weblogic cannot find it.
Any idea?
Thanks in advance for help,
with best regards,
Julian Legeny

Issue listeneing queue from Weblogic Cluster server with multiple managed server

Haveing issue listeneing queue from Weblogic Cluster server with multiple managed server.
Weblogic Cluster structure is like
Weblogic Cluster01
--ManagedServer01(http://server01.myhost.com:7001)
--ManagedServer02(http://server02.myhost.com:7001)
JMS Servers
JMSserver01 targeting: ManagedServer01
JMSserver02 targeting: ManagedServer02
JMSmodule
ConnectionFactory01 targeting:JMSserver01,JMSserver02
UDQueue01 targeting:JMSserver01,JMSserver02
Uniform Distributed Queue in Monitoring tab showing like this
mysystemmodule!JMSserver01@UDQueue01
mysystemmodule!JMSserver02@UDQueue01
So when I am sending message to any Host(by specifying the provider URL) its distributing equally on both server like
mysystemmodule!JMSserver01@UDQueue01 10
mysystemmodule!JMSserver02@UDQueue01 10
But when try to listen message from these queue, it is listening from one server, for which URL given to connect.
mysystemmodule!JMSserver01@UDQueue01 0
mysystemmodule!JMSserver02@UDQueue01 10
untill I connect to other server by giveing its URL, will not able to access other message left on the queue.
Solutions that tried
1) we have tried give both server URL coma sparated in provider URL
we need to configur same scenario for 5 managed server with 3 listener on other servers.
Do any one have solution for this.

You need to have:
1. Consumers connected to each UDQ member
OR
2. If no consumers in some of the members is expected, you can configure Forward Delay (specify the amount of time, in seconds, that a queue member with messages, but with no consumers, will wait before forwarding its messages to other queue members that do have consumers):
http://docs.oracle.com/cd/E12839_01/apirefs.1111/e13952/taskhelp/jms_modules/distributed_queues/ConfigureUDQGeneral.html
For example you can set it to 10 (10s)

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

Weblogic cluster for 24x7 environment and a front OHS server

Hi experts,
We are going to set up a reliable J2EE application server environment by using clustering webgoic servers on TWO nodes, and a front OHS https server in DMZ for load balancing.
I am new to weblogic cluster and load balance by OHS. I have visited this forum for Fusion MiddleWare clustering etc. Can some experts share some light on this?
Will our deployment architecture be able to handle the J2EE applications failover? In other word, we can restart one of Weblogic Managed Servers when a new release of J2EE codes are re-deployed without impacting business end users’s usage?
Problems we want to solve:
1. All J2EE applications are available for 24x7 even when new J2EE codes are released and deployed on weblogic Managed Servers ANY TIME, side-by-side deployment and restart a managed server if we need to clean the HTTP cache.
2. The J2EE applications should be accessed by external and internal users with a Single Access Point, like
https://apps.company1.com/j2ee1
https://apps.company2.com/j2ee1
https://apps.company1.com/j2ee2
https://apps.company2.com/j2ee2
All J2EE applications (j2ee1, j2ee2, j2ee3 etc) should be deployed on both of weblogic Servers in a cluster, and pointing to a SAME backend database.
Can some experts share with us the best practices on components and configurations? Thanks.

Seems your architecture is like Browser => OHS ( DMZ ) => Weblogic => DB OR Browser => HLB( like bigip ) => OHS ( DMZ ) => Weblogic => DB
Cluster is the solution for load balancing however if you are using OHS for redirection to weblogic then OHS does the load balancing in round robin way. using cluster in this way has a benefit of in case of any one of your managed server is down the OHS will divert connection request to any one of the active managed server ( you have to turn on dynamic list on at OHS ).
http://weblogicserveradministration.blogspot.com/2010/10/load-balancing-in-weblogic-server.html
Failover is something different, if in case any of the any managed server goes down then your user you get the application session from another server but new one, means the the tasks not saved by the users on earlier session will lost. for that yo need to use cluster and then need to enable the session replication. another best option is you can use the coherence web if you are using latest versions of weblogic supporting coherence web. with that you not need to worry on user sessions and you can start any of the managed server anytime without worrying about the user sessions.
http://weblogicserveradministration.blogspot.com/2010/10/manage-http-session-states-session.html
http://weblogicserveradministration.blogspot.com/2011/05/oracle-coherence-37-coherenceweb.html
http://weblogicserveradministration.blogspot.com/2010/11/clustering-part-i.html
another way is, you can use side by side deployment feature in case you don't want shutdown your application completely, with this, old connections and new requests will goes to old application and once new application activated all new requests will come to new application and once all requests on old application will complete that application will retire automatically.

StreamCorruptedException when starting Weblogic cluster

Hi, I have an application running on Weblogic Server 8.1 sp4 in clustered environment. When the cluster is restarted the first server restarts without errors but the second one has the following error message. What does the error message mean? Some messages have disappeared form the JMS queue when the cluster has been restarted. Does this error message have something to do with the disappeared messages?

Make sure that the JMS server isn't attempting to load a store that was created from a later version of WLS. Also, make sure that no two JMS servers share the same database table - otherwise they will corrupt each-other's data. I think the latter is likely the problem.

Singletons in WebLogic cluster

In my clustered EJB application, there are 3 stateless session beans that need to run as singleton services on exactly one node. So I implemented the interface weblogic.cluster.singleton.SingletonService in these beans with the activate and deactivate methods. The beans and all classes of the application are contained in an ear file I deploy to the entire cluster. Then I configured the bean classes as singletons using the WebLogic console administration (cluster details -> singleton service). After I activated this in changes center, I see a ClassNotFoundException with the class name of one of the beans. So I extracted the ear file to the domain/lib directory, restarted the server and tried again to configure the singleton classes. This time the activation failed because of another reason (HibernateException). I think the reason is, this operation is done in the context of my administration server, not of the cluster server. It seems this doesn't work.
Is it possible to deploy the EJB application with the beans as singletons?
I already found another solution: to set the maximum number of beans in weblogic-ejb-jar.xml, field max-beans-in-free-pool, to 1. This solution is a little bit dirty, after starting the servers, I get an exception on all other nodes complaining that it is not possible to deploy this bean. What I don't know: how would it be handled, if the node with the deployed beans is shut down? Are the beans deployed on the other nodes automatically (as I expect for singleton services) or keep undeployed?
Thanks in advance!
BTW: I'm using WebLogic 10.3 on Windows.

Maybe this will help: http://middlewaremagic.com/weblogic/?p=5799
Also to make Hibernate run on WebLogic you have perform certain steps, there is
problem with the antlr version that ships with Hibernate as another version of
antlr is already loaded in the system classpath of WebLogic.
Some instructions are presented here: http://middlewaremagic.com/weblogic/?p=5861

Anyone encountered this before in the clustered setup ?
Thanks,

Hello,
But if you see the trace, it is coming from the OOTB library. Isn't it ? It doesn't indicate if there is any issue in any custom beans.
java.io.NotSerializableException: com.thortech.xl.webclient.workflowutil.ImageGenerator$FieldMoreover, i see this error in the log with case 2: ("configure" data flow). However, it is working and the the UI is showing me the data flow with this error in the log.
My major concern is case 1: ("edit" workflow) which is not showing me anything on the UI ?
Ideally, it should trigger Nexaweb client to populate the workflows in the UI.
*1 interesting observation:*
If i go to "Design console" -> process definition -> "Render workflow",
then it opens the workflow in the default explorer and the url which is opened in the browser is same as the previous case. It is working here as expected. Does this means the problem is with Nexaweb client load in the UI in case 1. How to fix this ?
Please suggest.
Thanks,

WebLogicSession and X-WebLogic-Cluster-Hash cookies

 Hello, apologies up front if this has been posted before, I haven't
 been able to
 find any reference to it yet. First, how do I decode the
 WebLogicSession cookie
 between the HttpClusterSerlvet and the HTTP client to extract the IPs of the
 primary/backup cluster servers that have replicated my HTTP session?
 Second,
 how is the translation done between the WebLogicSession cookie
 (proxy<->client)
 and the X-WebLogic-Cluster-Hash (proxy<->cluster)?
 Thanks in advance for any responses,
 -Steven Vaughan


I'm not exactly sure what you are asking. Are you trying to configure a
 hardware load balancer or something like that in front of the proxy?
 If you take a look at the cookie information (you can do so online by using
 safe cookies at anonymizer.com for example) you will see the IP addresses
 embedded in the cookie data. Do you need to know exactly what the
 information/offsets there are in that data? Could you explain what you are
 trying to accomplish?
