Bi publisher cluster on weblogic 10.3

I'm trying to setup a BI publisher cluster on weblogic server. I managed to do it on on one physical machine. I deployed war application as an exploded archive and selected "I will make the deployment accessible from the following location C:\apps\xmlpsever.war", and in xmlp-server-config.xml I setup repository as "C:\apps\xmlpsever.war\home\repository\XMLP", and everything works fine.
When I try to do same thing, just that my weblogic machines are different physycal machines I have a problem. If I deploy an application in a war package it doesn't work, and if i deploy it as an exploded archive (like said in Bi publisher Installation Guide) it copies the application to all physical machines but application doesn't deploy well because of BI publisher repository path. I tried to put a repository in one folder, share that folder and then map it to X: on every machine, it doesn't help.
Thank you for any help regarding how to configure publisher repository, XMLDB or any solution?

your cluster is unicast or multicast? if you are using unicast, I would suggest switching to multicast and see if the problem still occurs.
keep us posted.

BI Publisher Cluster Deployment Issue

Hi All,
I have installed BI Publisher in two nodes A and B (stand alone basic). During scheduler configuration, I have checked cluster option. A load balancer has been configured to point to these two nodes.The data source is file system and location is on network file server.
I have a java program that call BI Publisher webservice and submit the job for scheduling. The java program points to load balancer ip. Currently I am facing two issues as below:
1. When I call BI Publisher webservice to schedule the job, I can see that the job is scheduled through one node only
2. Processing the scheduled job (report generation is distributed into two nodes. But this distribution is not even. If I shedule 5 jobs, Node A is executing one job while the other node executes reamining 4 jobs. Thus I have noticed that Node A remains idle after completing the job till the other node completes the report generation
Do I need to do make any changes/ perform additional configuration so that the job is distributed among the nodes evenly.
Your help will be highlu appreciated
Thanks

First, make sure you've got enough machine resources as BIEE11g is resources hungry.
Next, after installation you should have icons to start BIEE11g (try windows version as it is easier to start up).
Run the startBIEE11g script and it will take some minutes, be patient. Once you get all processes running
then you can try to login.
Take a look at my post:

Round Robin was not happening for my cluster with WebLogic Proxy Plugin

          Hi,
          I configured my cluster with software load balancer, HTTPClusterServlet. By default,
          it is load balancing with Round Robin Algorithm. That means one HTTP request
          goes to server1, and the other HTTP request goes to server2. However, it is not
          what I can see no matter for the requests in one HTTP session or not.
          Say I open two browser, and log into my application with two different users,
          one is "cyang", the other is "xpression". Then the HTTP request (for servlet/jsp)
          from two browsers always go to the same server1, server2 is not invoked at all.
          I did see one time, with only one session (one browser with "xPression" user log
          in), the most requests go to server1, suddenly I am brough into log in page, then
          I noticed that the request for "xPression" moved to server2 although server1 is
          still alive. Therefore, at most, I can say it is "Random", rather than "Round
          Robin".
          What is the real meaning for HTTP servlet/jsp load balancing algorithm? Does
          Round Robin mean request go to each server in turns? Does it have to be different
          session or it can be within one session?


It should be sticky. If not, then bug / config error.

Inconsistent message publishing times through weblogic JMS client

Hi,
We have a weblogic JMS application which we are deploying in a clustered weblogic enviornment. We are using distributed queues/topics with file store. We have both JMS cliient and server running on separate weblogic clusters. Most of the times it will take about 10 milli seconds to push the message into queue, but 1 in 50 messages takes about anywhere between 0.2 sec to 6 secs. Recently for three days it just took 10 msec for all the messages throught these three days and then started behaving erratically again. I am not able to really figure out why there is lot of deviation in the publishing times. When I monitor both my client and server through admin consiole, I don't see any stuck threads, heap size is normal, cpu load is normal, no problems with network. Please help me to figure out the root cause for abnormal publishing times.
Regards
Koti

Could you check if there are JVM garbage collections during some the publishing times.
In particular check if there are any full garbage collection occuring when you notice such a deviation in the publishing time.

Java publishing framework using Weblogic personalization

Hi All, Has anyone used the Weblogic personalization server/portal or
a different Weblogic product as a publishing framework.
We want to design a publishing system in which we can quickly create
templates for new type of content on the website, and provide an
interface for entering the data to the admins. The data can then be
presented using XML/XSL transformation, and the source can either be a
database or static XML file.
Cocoon does provide a framework that comes close to our requirements,
but as we are using weblogic it might be worth expoling if a
commercial product can be used for such a framework.
I am sure many people have a need to post content on the site and use
a variety of mechanisms to use it.
Also, can the Portal product be used to generate portlets which can be
placed on multiple pages. We are looking at 500+ pages in our site,
with 100+ portlets.
I can give more specific details if needed. Any help is appreciated.
Please feel free to also email at [email protected]
Thanks, Yogi.

Rejoining a cluster in WebLogic 5.1

          Sorry, I haven't had a chance to test this out, so here is a dumb
          question - once a server goes down in a cluster, I know the failure
          is detected by the peers and the server list is modified accordingly
          but what happens when the failed server comes back up and WebLogic
          is started again? Can it successfully join the already up and running
          cluster?
          Thanks

OS/hw based failover cluster for WebLogic Server 9.2 Standard Edition

Hi
Is it possible to run WebLogic Server 9.2 SE on OS/hardware based cluster?
I want to get an simple failover environment on a cluster of 2 nodes (active-passive).
Oracle Database can be run in such scenario with one license with a limit of up time for passive instance.
Is it the same with WLS licences?
Regards
WD

The problem doesn't look like it has anything to do with wappers per se. The stack indicates that the JVM died when the persistent store tried to invoke a standard Java synchronize operation. JVM crashes need to be analyzed by a JVM expert, so I second the suggestion to solicit help from JVM experts and/or filing a case with customer support. In the mean-time, you can probably work-around the issue by either (A) ensuring you have a recent version of the JVM installed, or (B) temporarily switching to the Sun JVM.

Issue when publishing application on Weblogic 12c

Hi everybody,
I am facing a strange issue with my web application when I try to deploy it on the web server (for information, I am working with Eclipse). I am saying that it is strange because it is not happening all the time (most of the time it is happening after a refresh of project sources to integrate changes made by other developers of the team). The second part why it is strange is because it is giving an error message that doesn't make sense for me as the class ApplicationServlet mentioned is present in my project and has no annotations inside.
Below is the error message :
weblogic.application.ModuleException: [HTTP:101371]There was a failure when processing annotations for application C:\workspaces\.metadata\.plugins\org.eclipse.core.resources\.projects\sample-app\beadep\sample_domain\sample-app. Ensure that the annotations are valid. The error is com.toto.sample.application.ApplicationServlet
And this is the stack trace :

Thanks in advance

Well, under Filters --> Char Restrictions & Default Values, I have the chars arranged in a particular order. But on the portal, under the 'Free Chars' tab, I still see them arranged in alphabetical order. So, my query seems to have no effect on how the FCs are being displayed on the portal.
Can I change something in the web template? Or is this a portal property?
Regards.

Error when setting up cluster in weblogic 10.3.6

Hi All,
We are trying to set up a cluster with 2 managed servers in WLS 10.3.6. The issue is that we do not manage to deploy our application on the managed server as when we start the managed servesr we have the following error message :
javax.naming.NameNotFoundException: While trying to lookup 'ouaf.servicebean' didn't find subcontext 'ouaf'. Resolved '' [Root exception is javax.naming.NameNotFoundException: While trying to lookup 'ouaf.servicebean' didn't find subcontext 'ouaf'. Resolved '']; remaining name 'ouaf/servicebean'
Unfotunately, we are failing to resolve this issue. Any help would be greatly appreciated !!!
Many thanks.

HI,
Just try to clear tmp and cache once a see if you still face same problem.
If not please put the complete error stack to verify what exactly going on there.

Cluster License weblogic 10

Do I need a cluster license if I'm runnning a cluster for testing and evaluation purpose?

          You don't need any special cluster license. You can use default one.
          Remember only about 5 connections limitation per single server.

Weblogic JMS Cluster

Hi,
          I have a 6.1 cluster that has a JMS server A and a JMS Server B
          deployed and running on each of the managed nodes. As destination I
          created a topic with the same name for each JMS Server. The connection
          factories I deployed to the cluster only.
          My problem is, when I start the second managed server, I get the
          following error:
          <Error> <Cluster> <Conflict start: You tried to bind an object under
          the name
          com.csg.pb.tit.tms.TMSSignalTopic in the JNDI tree. The object you
          have bound
          from 169.59.5.26 is non clusterable and you have tried to bind more
          than once
          from two or more servers. Such objects can only deployed from one
          server.>
          When I understand correctly, this happens because the JNDI tree gets
          distributed to all nodes of the cluster, so there would be two object
          with the same name. How do I solve this situation? Do I have the
          specify different names for topics in different JMSServer running in a
          cluster? How would the load balancing work?
          Please help. Thanks in advance

          Thanks for your help so far, I installed the patch and got things
          working. However I still have some open points where you might be able
          to help.
          Let's assume I don't have these smart forwarders and I have four
          topics per JMSServer deployed to two managed nodes. Connection
          factories deployed to the cluster. When I connect N publishers
          through the cluster, messages from one publisher end up in the
          appropriate topic on nodeA, messages from another publisher end up in
          the appropriate topic on nodeB. Now when I connect a durable
          subscriber via the cluster I only get messages from topics from one of
          the managed nodes, right? (This is exactly what I am seeing in my
          tests) Connecting durable subscribers to each managed node is not
          possible because of JNDI (throws exception like
          InstanceAlreadyExists). How would I connect a subscriber so that it
          subscribes to the right topics on the right node ( one the works with
          the previously described publisher)?
          All this leads me to the conclusion, that without the forwarders, a
          JMS cluster with Weblogic 6.1 is not so powerful, it basically does
          just load balacing.
          Is this correct or am I missing something important here?
          Thanks a lot and have a nice weekend

Weblogic - Fusion Middleware Cluster - Clarification - 11g

Hello All,
I've checked the forum and would need just a little clarification regarding weblogic cluster & fusion Middleware + Load Balancing.
My current Setup is:
==============
1 APP Server: Runs Fusion Middleware 11g Forms and Reports + Weblogic + OHS (windows 2008R2)
1 DB Server: Standalone database 11gR2 installation (windows 2008R2)
I've been asked to add a new app server and setup load balancing between the two app servers in order to split the incoming forms & reports requests.
What do I do? Do I install the new app server like the first one and just add it to an existing domain(clustering)? Is there a difference between fusion middleware clustering and weblogic clustering (as in database RAC - the whole idea being failover 24/7 no single point of failure?)
I would appreciate any assistance, and need not great detail, just need to make sense of the whole thing.
I'm already on with the following document: [http://docs.oracle.com/cd/E21764_01/web.1111/e13709/toc.htm]
Thanks in advance
Jan S.

Hi Jan
You are almost there. I would like to clarify some points for you.
1. You already have WLS + Forms/Reports and of course Backend RCU Database that has all the meta data for Forms/Reports. This RCU database is on single server Oracle database.
I've been asked to add a new app server and setup load balancing between the two app servers in order to split the incoming forms & reports requests.
2. The first question for above requirement is, do you need the new Server on the same Existing physical box or a different remote physical box. If on the same physical box (which I doubt), then there is NO need to install any new software like WLS, Forms/Reports etc. All you do is create a new Managed Server and add it to your existing Domain. NOW, do you currently have a Clustered Domain. If you, all you do is add this new server to that cluster. If not, then you need to add a New cluster and add your old and this NEW managed server to that Cluster. If your existing domain is only single server and is very recent, I would prefer create a brand new Cluster domain with Different Port numbers (you can change port numbers anytime later also). Then add/create one or two managed servers.
3. If you are give a new physical box for this new managed server, then YES, you do need to install exactly SAME version of Weblogic Server and same version of Forms/Reports server on this new machine. Then create a Cluster Domain with 2 managed servers. One managed server on first box where you will have Admin Server + Managed Server 1. Then run pack command. Go to other machine. Run unpack command to create second Managed Server. Now you got 2 managed servers in a Single Clustered Domain.
4. Now comes the Load Balancing Part. Never ever expose the individual managed server host and port and WebApp urls for any Clustered Domain. Instead install Apache Http Web App Server which I guess is same as Oracle Http Server. Oracle renamed it (there is no need for this, but it may be company policy). Anyhow all you do is, just install Apache Web Server. Copy some .dll (.so on linux) files to this apache installation. Then update httpd.conf file or weblogic.conf file with details of clustered weblogic domain managed servers host, port, url patterns etc.
5. All the External Requests will now go to Apache Web Server like http://apachehost:apacheport/xxxUrl. This Apache will take care of LOAD Balancing, Failover etc and based on input url pattern will redirect requests to back end cluster of weblogic managed servers.
6. The backend RCU database that has Metadata for Forms/Reports NEED NOT be Clustered. If you really have extremely heavy data, then you can have Oracle RAC database. Have multiple DB Nodes in RAC. For each Node, create a DataSource in Weblogic conolse and finally one master Multi Data Soiurce that uses all these single Datasources. But very rarely you really need RAC or clustered database for RCU. So for now, just go with single non-clustered Database that has RCU Schemas.
In conclusion, even though you have Forms/Reports, just follow the standard normal Weblogic Clustered domain Architecture for your requirement. All clustering is at application server level and nothing to do with any Oracles softwares like SOA/BPM, Forms/Report, BI etc etc.

Multiple open db connections in a weblogic cluster

we have created a cluster in weblogic with oracle database.
Whenever we are starting the cluster (managed servers), there are a lot of connections are opening in database (around 150 in database). Although we have set max capacity of cgDataSource, cgDataSourcenoXA and wlsjmsreportDS as 20. So ideally there should not be more than 60 connections open at any point of time.
We are using OSB 10gR3 in Linux 64 bit platform.

The max capacity for a data source is per node in the cluster (if it's targeted to the cluster).
So if you have 3 data sources, with max capacity of 20 each and two nodes in your cluster you should have around 3*20*2 = 120 connections.
Of course at startup WebLogic only creates the number of connections specified in the initial capacity.

Eclipse + Oracle WebLogic Server Tools - stuck during publishing

Hello,
I'm experiencing a problem publishing to my application server in Eclipse, and would very much appreciate any help given.
Server: WebLogic 10gR3
Eclipse: Ganymede JEE SR2
Oracle WebLogic Server Tools: 1.2.0.200907171310
OS: Windows XP 32 bit
JVM: Sun 6u13
In my workspace:
- Several Java projects
- Several EJB projects
- Several web projects
- One connector project
- One EAR project, referencing all other projects as its JEE modules
- One WebLogic server in my "Servers" view, defined to deploy my EAR project
Summary of my problem:
Sometimes, and it seems pretty random, when starting the server - the "Publishing to Oracle WebLogic server" operation would never stop (can be seen in the "Progress" view). As a result, Eclipse is essentially stuck, as all other operations, such as saving a file etc', would not be performed since they would be waiting for the publish operation to complete.
I did notice that a trigger for this is a deployment failure, such as a badly-defined application-module-datasource, or a failed startup task, but I have also experienced this with a good deployment as well.
I am, literally, clueless. I have tried the new Galileo but it's too buggy, had some weird phenomenons there, and I have also tried the OEPE Galileo preview and got some weird phenomenons there as well.
Again, your help would be very much appreciated.
Thanks in advance,
