Weblogic 9 vertical clustering

I have FR web deployed in the Weblogic 9, which is a part of Oracle EPM. Need to do vertical clustring.
Can any one tell me the steps of creating 3 instance in the same server.

Weblogic & webcache clustering

Hi Guru,
We have 2 node 11gR2 RAC, 2 application server & load balancing H/W (Brocade).
Each node of appserver installed weblogic 10.3.5 & webcache 11.1.1.5.
I'm planning to install weblogic domain clustering on both appserver (appserver 1 : admin server, soa_server ; appserver 2: soa_server).
so my question are:
1. is it possible, config web cache on both appserver connect to individual soa_server, load balancing through H/W; or we just need install webcache on appserver1 and let webcache do balancing on soa_server at appserver1 & appserver2.
2. which is best option, do load balancing with H/W, webcache or proxy server.
3. which is best option for type of datasource if we want to connect to RAC DB, gridlink datasource or muti-datasource ?
4. is it possible to 1 machine/server have more than 1 node . ie. appserver 1 : admin server, soa_server1 , soa_server2, ...
Need your advices, and sharing your experiences
Thx in advance.

1 and 2) http://docs.oracle.com/cd/E21764_01/core.1111/e12036/overview.htm#CHDJDIEH (shows a reference topology)
3) grid link (http://docs.oracle.com/cd/E17904_01/web.1111/e13737/gridlink_datasources.htm)
4) Yes as long as you have enough resources (CPU and memory) on that machine to run multiple servers

NPE using weblogic.httpd.clustering.enable

I'm having some difficulty trying to configure a cluster. If I set the
          property "weblogic.httpd.clustering.enable" to true I will get the attached
          NullPointerException. Where did I do wrong?
          Thanks for help.

          But I do need to use clustering and in order to do that
          I gotta have the weblogic.httpd.clustering.enable set to true among
          all other cluster related properties. What would be the point of using session persistence without
          actually running your servers in a cluster ?
          Right ??

ORACLE WEBLogic 12C Clustering of Admin Server ?

Hi ,
I have setup WebLogic Server 12c on solaris 10 u11, as cluster.
For cluster of managed servers, it works fine.
My Question is, can we run Admin Server from two nodes of cluster?
example: Node 1, created Admin Server, Cluster (F-End1/F-End2) Managed Servers
F-End1 on node1, and F-End2 on node2.
Now for some reason, Node1 has some hardware problem, can i run Admin Server from Node2 ?
I have followed the setup from this website<>
http://www.oracle-base.com/articles/11g/weblogic-11g-clustered-domains.php
Followed Same, Pack/Unpack, Enroll.
Now from Node 1, i can run, Node Manager, ./startweblogic.sh   and it takes me to the Admin Server.
from there i can manage every thing.
Question is, can i run Admin Server form Node2? if yes, how?

Node1: 10.0.1.179     Admin Server :7001      F-End-1 7003 B-End1   7020
Node2: 10.0.1.177                                       F-End-2   7003 B-End2   7020
when i try to run the Admin Server from the Node2, i get error (By 1st running the Node Manager)

Weblogic JMS clustering

Hi All,
I need help understanding weblogic JMS clustering. I read few documents regarding this but not very clear about it.
Hope to get help/suggestion here.
I have following setup
box1 - adminserver, osbserver1
box2- osbserver2
osbserver1 and osbserver2 are clustered together
I have a JMS server created each one for each managed server (OSB server) in the cluster. These JMS servers are non-persistent. persistent store is "None".
I have one JMS module created with connection factory, distributed Qs and are associated with a subdeployment that is targeting to the cluster
I have all the servers(admin server and both OSB servers) are in running state
To monitor JMS server I go to services->JMS Servers
I see jmsserver1 which is targeted to osbserver1 has "Health" is marked as "OK"
jmserver2 which is targeted to osbserver2 has no "health" check
If I go to environment->servers , I see all the 3 servers are marked as "RUNNING" with "Health" OK
As a note I created managed server in the second box before creating the JMS server and resources.
And I do not have any nodemanager setup at this point.
How would I know the JMSserver in both servers are active and have no issues ?
Do I need to do anything to start JMSServer in OSBServer2 ?

Should the JMS Server/JMS modules already be created so that the remote managed server will get configuration of these setup?No. This is not how resorces are created. Pack/unpack is used for creating the domains, ONCE. Later on you may very well use Weblogic admin console to create the resources and target/untarget those.
As a note I do not have node managed setup yet. It is recommended that you use node manager in environments where servers may be installed on different machines -
http://download.oracle.com/docs/cd/E14571_01/web.1111/e13740/toc.htm
To me, it seems a network/cluster communication issue. If you have Oracle Support, better raise a SR with them to find out the exact issue as they would be in better position to understand your architecture and analyzing logs. You may also raise a thread in Oracle Weblogic forum to get a suggestion from a Weblogic expert -

WebLogic Server clusters not high available!!

          I'm working with WebLogic Server 6.0.
          I try to connect to cluster using explicit IP addresses.
          For this case,first ,I cluster server A,B and C ,then client try to look up home
          interface at server A.
          After server A return home reference ,client creates EJB object and calls method
          using that reference .
          If server A fail, it still working with others server ,B and C.
          But if new client try to find home reference at server A ,he can't.
          This situation means that WebLogic Server cluster is not high availability or
          I did something wrong with configuration?
          And if I missed something ,how can I fix it?
          Thanks for your attention.


Hi King,
          If you look up at a non-existent IP/port, then it will not respond. That is
          expected behavior.
          You should not be using an explicit IP like that. At least use DNS round
          robin.

Weblogic portal clustering

Hi,
Help Please!
Now we need migrate an application to clustering environment. But there are some confusing scenario.
What we have done are:
1. make all objects in session serializable. For thoese unserializable, declare them as transient and take other workaround to assign value to them when accessed.
2. put up a clustering environment with two managed servers. Here we use IIS as frontend, and weblogic IIS plugin as cluster proxy. In proxy.ini file, we add WeblogicCluster paramter to specify managed server list.
3. add persistantStoreType/replicated session attribute to weblogic.xml
Then we code a simple application to test session replication. The application includes one pageflow. The pageflow has one class level variable and action form.
Now what confused us is the behavior of app upon clustering is not consistant. At the beginning, the session duplication seems works. So after re-setting the pageflow class level variable in a action, the pageflow instance seems duplicated to another managed server. So I stoped current one, and access another action to print out the variable. It works!
But after undeploying/redeploying the application serveral times, the session replication never works again. And each time, when printing out the variable value, it will be the initial value.
Question:
1. Is any other steps/special configuration needed to make clustering works?
2. Portal's pageflow instance is stored in session, is there any special coding criteria to follow to make pageflow instance replicatable?
3. Now in the managed servers and admin server's console, I never see such a debug log:
<i><Oct 9, 2003 12:38:21 PM PDT> <Debug> <Cluster> <000000>

Weblog 6 Clustering basic question

I am trying to setup Weblogic ver 6.0 Clustering on my Windows NT machine.
          From the weblogic console i created a Cluster, which has the IP address of
          my machine, and given it some name MyCluster.
          I have not given any Multicast IP address to it.
          On the left hand pane : For my servers under Servers/exampleServer
          On the right hand pane :
          I go to Configuration/Cluster window and choose MyCluster for the cluster
          field for my Server exampleServer.
          And click Apply.
          This results in error messages in my Weblogic command line window with lots
          of NullPointerExceptions etc...
          Have i missed any step here ?
          Can any one please give me a step by step guide to creating a Cluster, and
          then adding server (instances ?) to it.
          Do i need more than one IP address (i guess...) ?


          A cluster needs at least TWO IPs (2 IPs in 1 PC or 2 PCs).
          Your IP for cluster should be like 1.1.1.1,1.1.1.2 or cluster.domain
          with two IPs assigned to it.
          That should be why you got NullPoint for the missing 2nd IP.
          You might follow my attached ReadMe.doc and modify my sample config.xml
          for both machines/locations (use same config.xml on the two), modify
          my startExamplesCluster.cmd (for master), startExamplesSlave.cmd
          (for slave) and setExamplesEnv.cmd (for both) to fit yours, and
          try.
          config.xml has all the result you can make in console.
          Cluster feature in WL6 is far from perfect, don't guess the ideal
          possibilities all the time.
          Good luck!

BPM Enterprise for weblogic and clusters

good morning every body
what is the best practice for High Avalibilty Clustered environement for BPM enterprise for weblogic ?
i know that clustering is done on the Weblogic server side but is there is any constraints regarding to ALBPM clustering
if some one would direct me to a diagram of the clustring best practice it would be appreciated!

Need Help on Weblogic JMS Clustering

Hi All
Our code is moving to a clustered environment (2 OSB managed servers), in order to support JMS clustering i have already done the below, I just need your advice whether i have done it correctly or not. Please advise
1) Created 2 JMS Servers, targeted one JMS Server on OSB MS 1 and second JMS Server on OSB MS 2.
2) Created distributed destinations (Queues and Topics) subdeployment on both JMS Servers.
3) Targeted all connection factories to OSB Clsuter. Load Balancing and Server Affinity is enabled by default. Should server affinity be disabled for proper load balancing to occur? Please advise on this
3) JMS Proxy and business services use cluster URL's now (jms://serverA:7001,serverB:7001/CF/QueueOrTopic). I Hope its correct? Please advise
Is there any other setting that i need to do or i have missed out? Please let us know.
Also, one more thing we are calling SOA Composites via SOA-Direct protocol in OSB. The SOA Servers owned by some other team will also be load balanced. Since this is a t3 call, HTTP load balancer would not come into picture here, right? How do i load balance this outgoing call from business service (2 options bellow)
1) t3://server1:8001,server2:8001/default/ABCProduct!1.0/ABCService_DirectBinding
2) Specifying two individual endpoints and selecting load balancing algorithm as Round Robin
t3://server1:8001/default/ABCProduct!1.0/ABCService_DirectBinding
t3://server2:8001/default/ABCProduct!1.0/ABCService_DirectBinding
what is the diff between the above 2 options? Also, if one of the SOA nodes go down, than which option would automatically redirect to other node. We have to ensure this as the HTTP load balancer ensures this thing. Thanks

Hi Amit,
The first part looks correct.
Create two jms servers (jmsosb1, jmsobs2)
Create data source and jndi location
create foreign connection factory under JmsModule, create destination and connection factory.
the cluster business service end point will be
jms:///<<ForeignConnectionFactory Name>>/<<destination local jndi name>>
The second part SOA endpoint will be in cluster environment as follows:
http://<< cluster name>>/soa-infra/services/default/<<composite name>>/<<servicename>>
example:
http://test.ch/soa-infra/services/default/cm.conn.bp.test/test_client_ep
or if you want to invoke two nodes directly you use below url as well.
http://<<SOAservername1>>:<<port>>,<<SOAservername2>>:<<port>>//soa-infra/services/default/<<composite name>>/<<servicename>>

Padmanabham

Iplanet-Weblogic in clustering

          My current environment is like this
          1)i have installed Iplanet on Win2000
          2)i have already setup a cluster between two machines one running on solaris/sparc
          and another on HPUnix
          3)Now i want to use Iplanet as webserver using proxy plugin
          Can anybody tell me with this setup can Iplanet running on win2000 can communicate
          with weblogic cluster running on solaris,HPunix machines
          If ok then what is the proxyplugin should i use and minmal configuration steps
          that is to be done
          Regards

          Ranga Rao,
          See the following URL:
          http://e-docs.bea.com/wls/docs61/adminguide/nsapi.html
          This assumes that you're using WebLogic 6.1. Search BEA's "e-docs"
          site if you're running another version.

Problem in clustered weblogic 9.1 servers duplicating quartz jobs

We have a web application expected to run quartz job to insert one row in database, but it inserted 2 rows in database. The quartz job is kicked off by a servlet that is loaded when weblogic server is started.
I understand the qaurtz job should be clustered with jdbcjobstore, too.
My question is:
if clustered weblogic server is considered as one running instance and the quartz job is kicked by a java servlet that is preloaded when weblogic server started, how could a job shceduled at a specific time (example, 3am daily) will be run twice? i.e. two clustered welogic server each run the job once. Does that mean our weblogic server clustering is not configured right?
The two clustered weblogic servers are on separate Unix machine and synchronized in time.
Any idea for the problem? Just weblogic cluster side, not quartz side.
thanks

The "jsp:directive.include" tag is only valid in an well-formed XML file that specifies all the relevant namespaces. The "jsp:include" tag is used in a JSP file. I'll bet the beginning of your file shows that you don't have a valid and well-formed XML file.
If you found that "jsp:include" worked, then that confirms you have an ordinary JSP file here. Why are you trying to use the XML form? The result of "jsp:include" in a JSP file will be exactly the same as the analogous tag in an XML file.

Clustering issue with WLCS 3.2 weblogic 5.1 and service pack 8

I'm having a problem with Portlets on a page with commerce server 3.2 on
          Cluster A below. One Portal page has multiple portlets on it. When the
          Portal Page executes the portlets are being scheduled across both SCCWLS00
          and SCCWLS01 and they are not able to share the session. Thus they will
          throw exceptions trying to read properties from the WLCS profile which is
          shared.
          In Cluster B, When the portal page excutes all portlets are "pinned" to that
          server and they share the information perfectly. Both Cluster Groups have
          their CLUSTER-wide weblogic.properties file set for
          weblogic.httpd.clustering.enable=true
          weblogic.httpd.session.persistence=true
          weblogic.httpd.session.persistentStoreType=replicated
          weblogic.httpd.register.cluster=weblogic.servlet.internal.HttpClusterServlet
          Any ideas on why this is happening? And How I can correct it?

What kind of problem do you have?
If it's not connected with JDBC, you'd better post your question
in webservices newsgroup.

hy out there.
i've been working with apache soap on wl 5.1 for a while now, and

Weblogic clustering - Non session objects

Hi,
I have an app that doesn't have any HttpSession object or EJBs. We have only one servlet for entire application that works as a controller and we store all the information regarding the user in the servlet instance variable as cache. None of our objects are Serializable. Can i deploy my application on weblogic cluster. Will weblogic support clustering for thsi kind of applications. We have only one servlet and all other classes are normal java classes. No JSP, EJB etc. No HttpSession or ApplicationContext of servlets are being used.
thanks,
webbie.

Hi,
The There are basically two reasons ...for which we want Clustering:
<h3><font color=maroon>Reason - 1): Failover</font></h3>
This feature needs HttpSession replication...Failover means if a Userhas Logged in to our application and accessing some pages ...then his HttpSession Replica will be available in a Secondary WebLogic Server so...even if his Promary WebLogic Server Goes Down ...His Session data will not be lost...and client can interact with the Application without any Interruption. To Enable Failover in your Clustered Application you need to provide the <persistent-store-type>Tag inside your "<Application>/WEB-INF/weblogic.xml"
   <session-descriptor>
      <persistent-store-type>replicated</persistent-store-type>
   </session-descriptor>
<font color=red><b>NOTE:</b> until u dont put <persistent-store-type> Tag inside your "weblogic.xml" file...by default HttpSession replication will be disabled....because it's default value is "inMemory" means even If your Application has HttpSession ... it wont be replicated on Secondary Server.</font>
<h3><font color=maroon>Reason - 2): LoadBalancing</font></h3>
This feature has NOTHING TO DO with HttpSession replication (in general). It means simply different clients request will be processed by different WebLogic Server Instances in a Round-Robin fashion. I Think this is what you want to implement. Because your application is not using any HttpSession .So thet Application willl not have any Failover. But LoadBalancing is the Default Feature of WebLogic Cluster. U need not to do anything additionally to Achieve it.
<font color=green><b>Note:</b>Means Without Having HttpSession Objects in your Application Still u can have WebLogic Clustering Feature to get the benifit of LoadBalancing.</font>
