Clustering 5 nodes with Weblogic 5.1.0 sp6

When setting up a cluster of 5 nodes, I'm seeing that only 3 of the 5 nodes
          respond to when accessing SessionServlet (from weblogic examples. When I
          make a request to the other 2 nodes in the cluster, I see the attached
          stacktrace (using kill -QUIT) on the JVM and the browser times out.
          I am accessing each node in the cluster directly using the URL
          http://<nodename>:7001/session.
          Each node in the cluster is started using the command below. Note that I am
          using nativeIO (weblogic.system.nativeIO.enable=true), which starts 3 posix
          threads for socket polling. Does that number have anything to do with the 3
          nodes that respond, or it just a coincidence?
          Ravi.

Problems with weblogic clustering in 6.1 sp3

We have spent a lot of time trying to get our application deployed to
          a cluster using weblogic 6.1 sp3 and we consistently receive a failure
          when we attempt to start the managed server. This was not a problem
          with weblogic sp1--we got our application to deploy to the cluster
          successfully; although there was another weblogic bug there with
          clients accessing EJB clusters--we won't go into that here...
          We have tried this on both a Windows 2000 machine and an HP machine
          running weblogic sp3. The same error occurs on both platforms.
          The error in deploying our application to the cluster against weblogic
          sp3 looks to have to do with our custom security realm. Inside our
          custom realm we make use of a configurable providerUrl which we set to
          the cluster address/port. The custom realm makes a call where it
          passes in the providerUrl to:
               weblogic.management.Helper.getMBeanHome(..., providerUrl,...)
          When we have our providerUrl set to the cluster address/port--e.g.,
               t3://clustermember1:7001
          and attempt to start the managed server we get the error:
          Starting WebLogic Server ....
          Connecting to http://adminserver:7117...
          The WebLogic Server did not start up properly.
          Exception raised:
          weblogic.management.configuration.ConfigurationException:

          When we have our providerUrl set to the admin server address--e.g.,
               t3://adminserver:7117
          everything starts up fine.
          Does anyone know why this would work on sp1 and not sp3 of weblogic
          6.1?
          We verified that all passwords are correct and everything else we
          could determine--any ideas would be helpful.
          We don't want the providerUrl to point at our admin server, we want it
          to point at the cluster address/port.
          When we get the managed server error, we received this error on the
          AdminServer:

          Thanks for any help.

Bottom line:
          In our custom realm we were not handling user guest correctly. Even if you
          have guest user disabled, Weblogic seems to have hard-coded guest to
          send messages to the cluster every-so-often. Not sure there--couldn't get
          an answer out of bea as to exactly why we see guest still being used...
          It seems that with sp3, the user guest interaction started happening earlier
          than it did with sp1, consequently making our realm code fail when trying to
          retrieve the guest user like someone we knew about in our system.
          Hence, our getUser and authUserPassword methods now return null for both
          users guest and system, making the secondary realm (file realm) be used to
          authenticate and resolve guest & system. BEA helped get our code fixed;
          however, we still don't have a lot of depth in understanding Weblogic
          server's use of guest...
          Apparently, in 7.x the guest & system user behavior and configuration is
          different also... We'll see when we start digging into that migration.

Problem with WebLogic 10.3.3, Apache 2.2.3 and WebLogic Apache proxy plugin

I have a problem with using Apache 2.2.3 as a WebLogic SSL proxy. I have Apache 2.2 running and successfully configured an SSL cert, config in ssl.conf is...
<VirtualHost secure.daftdonkey.com>
# Setup SSL for secure.daftdonkey.com
ServerName secure.daftdonkey.com
SSLEngine On
SSLCertificateFile /oracle/secure/secure.daftdonkey.com.crt
SSLCertificateKeyFile /oracle/secure/secure.daftdonkey.com.key
SSLCertificateChainFile /oracle/secure/gd_bundle.crt
</VirtualHost>
This works fine
Now I want Apache to proxy requests to my WebLogic Server and secure them over SSL as well
e.g. a request to https://secure.daftdonkey.com/service goes to https://weblogic.internal.site/service
I have downloaded and configured the weblogic module and tested it handling traffic for HTTP and that worked, then I switched the WebLogic module to use SSL.
LoadModule weblogic_module modules/mod_wl.so
<IfModule mod_weblogic.c>
WebLogicHost weblogic.internal.site
WebLogicPort 16101
Debug ALL
SecureProxy ON
WLSSLWallet /oracle/secure/my-wallet
WLLogFile /tmp/wl-proxy.log
</IfModule>
<Location /service>
SetHandler weblogic-handler
</Location>
Starting Apache throws the error. I think this is my main problem, i've searched support.oracle.com and not found anything.
[Mon Jun 07 23:00:48 2010] [crit] (20014)Internal error: WL SSL Init failed for server: (null) on 0
but Apache starts... I get this error when I make a request to https://secure.daftdonkey.com/service
Failure of server APACHE bridge:
No backend server available for connection: timed out after 10 seconds or idempotent set to OFF.
Looking into the log /tmp/wl-proxy.log I see....

I found the answer to this. The documentation is not clear enough, LD_LIBRARY_PATH MUST be set and MUST have a pointer to the directory where the SSL .so modules are. I wrote up a blog article explaining the configuration and detailed this issue.

Security violation exception with Weblogic cluster installation on OIm 9.1

Hi,
I have OIM9.1 installed on weblogic 8.1 SP4 in clustered environment, which more often than not seems to work fine. But some time I get following exception on server console/log file which causes certain provisioning task to be rejected...
at weblogic.kernel.ExecuteThread.execute(ExecuteThread.java:224)

Problem is, I get this exception only 4 out of 6 times (when it is least expected). I have googled, and tried all possible means but have't been able to resolve it. One more thing I am sure of is, it only comes with Weblogic installation not with Jboss. So there should be some configuration issue with weblogic installation.
Any suggestions would be useful...

No Response???
Where are the good guys??

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.

Using StoneBeat WebCluster load balancing with WebLogic

          Hi,
          I have done some testing of WebLogic Server with my company's StoneBeat WebCluster
          distributed load balancing software. This might be one more option to consider
          as a load balancing solution for WLS. It is advanced in the sense that load balancing
          is really dynamic, there are no single-points of failure (distributed architecture)
          and there is a very good, configurable test subsystem that runs on each cluster
          node to check for overload situations, HW/OS failures, ...
          In the initial testing, the WebCluster load balancing works with WebLogic replication,
          although there are some cases that need mroe consideration (please see below).
          I had to get a patch to WLS6SP1 on NT to make WLS' multicast work when there are
          several NICs on the cluster nodes.
          However, there is one case which causes problems:
          - I have 3 cluster nodes
          - P: 2, S: 3 (SessionServlet = 1)
          - 2: offline - P: 3, S: 1 (SessionServlet = 2; WebCluster randomly selected a
          new node to handle the connection)
          - 2: online - P: 2, S: ? (SessionServlet = 3, WebCluster redistributes the load
          when a node goes online)
          - 2: offline
          - P: 3, S: 1 (__SessionServlet = 1__) NB!
          The log messages show that when node 2 comes back online it retrieves the replica
          from the secondary (node 1) and not from the primary (node 3). After a while (5-6
          minutes), node 3 tries to update the replica on node 1. Node 1 considers this
          a stale update request and removes the Primary 16... (node name) and then the
          secondary for 16... (the replicated object). Then there's a message (still on
          node 1) that it is unable to find object 16... Back on node 3 the primary for
          16... is removed.
          From the WLS6 documentation (under the discussion of using replication with external
          HW load balancing solutions) I thought that this case would have been handled:
          - it is stated that after the failure of a node, if the HWLB box sends the next
          request to a node where there is no replica, WLS is able to retrieve the replica
          - to be fair, this is what happens: when node 2 came back online, it retrieved
          the replica from node 1 (the secondary) - I suppose that there is an assumption
          that if a request arrives to a node without a replica, the primary __must have
          failed__
          Is there any way to get around this problem?
          Admittedly, WebCluster has a problem in that the stickyness of connections is
          not perfect: - when a node goes online, a connection that was correctly persisted
          (based on either source-ip or source-network address) may be moved to a new node
          since the load is redistributed. Our load balancing is very dynamic, but doesn't
          maintain a list of who is connected to which node when resistribution takes place

Rick,
You may want to look at the Alteon and F5 configuration we have on edocs.
Take a look at the following URLs for a possible solution

Using p3p with Weblogic/CSS

I am trying to use p3p policy and compact privacy policy.
We have Weblogic as App server and a hardware CSS to maintain session on weblogic
clusters.
The browser on client end is accpeting cookie, but I dont see the actual cookie
being placed.
The cookie contains session info and is used by CSS to maintain sticky to the
same managed server.
Am sending cpmpact policy using Meta tag in my JSPs
ANyone had similiar problem.

Hi.
          Hmm, since WLS execute threads never die, I don't know that your threadlocal variables
          will get cleaned up or gc'd until the server is shutdown.

WD ABAP: Recursion Nodes that Repeat Tree Nodes with Embedded Tables ???

At Rich H's suggestion, I'm posting this here as well as in the blogs.
Suppose you've got a tree context with a node that has a table embedded under it. (For example, the TREE_WITH_TABLE view of WDR_TEST_EVNT has this kind of context substructure.) Call this node "NODE_WITH_TABLE."
You now define a recursion node underneath "NODE_WITH_TABLE" and specify "NODE_WITH_TABLE" as the repeated node for this recursion node. Call this recurion node "RECURSION_NODE".
Lo and behold - the table fills properly when you're on any instance of "NODE_WITH_TABLE", but not when you're on an instance of "RECURSION_NODE".
I'm hoping that:
a) I'm doing something wrong;
OR
b) There's an easy work-around/alternative I'm not seeing
OR
c) SAP will give recursion nodes enough memory to carry any table(s) embedded in the nodes they're repeating.
'Cause I sure don't want to have to define "n" levels of tree-nodes that have different copies of the same table(s) embedded in them.

Maybe you might want to back out your weblog as it is not really a place to ask these types of questions. Think of it this way, if you are allowed to do this type of weblog, what is stopping any other weblogger. Hence the weblogs would just be another forum, which I don't think anyone wants.

Can I integrate BPM with WebLogic Portal virtual content repository?

For example, when there is a new added node in WebLogic Portal virtual content repository, the workflow triggerd, and start a workflow instance on that node.
May be the node is a document, I'd like the document have a complex approval process.
My question is, there are many nodes so many workflow instance after I added many documents, so how can I know which node is combined with which workflow instance? May be in workflow process ,I'd like to get and set the node metadata or something else with the WebLogic Portal virtual content repository, how can I process data between BPM and WebLogic Portal VCR?

With regard to inline editing with Content Presenter in WLP 10.2, you should know that this "feature" is simply an example of how you might author advanced display templates.. The sample application for Content Presenter has a display template which is used to allow this inline editing. The template is just a sample and source code is provided. For your purposes, you can author your own display template which can provide inline edit even if Library Services are enabled. You'll probably want to enable version preview and approval to the template as well. It's a little more work, but certainly possible.

Any kind of integration experience with Weblogic JMS and Oracle AQ?

Hi,
In my company I work with java developers who believe in some kind of "holly" database independence I don't understand and as a result my life as a database developer is hell on earth.. Yesterday we again started to discuss, this time where to log, they believe database is slow and prefer logging to filesystem, after some hours finally I could convince them for some operational and reporting needs to use the database and will do this in an asyncronous way whiich they won't get slow. After all I believe the reason for a database is data, this is the place where data lives, and with the correct desing and implementation logging to database would perform better.
I love Oracle features, and know that we paid a lot for this software, so today I started investigating this promised solution. And quickly I found AQ and JMS topics in the documentation :)
After this introduction here is my problem; my company use BEA Weblogic as application server and the java guys want AQ to automatically (but of course with some delay) take their JMS log requests into database tables. Does any one have similar application experience, or any kind of integration experience with Weblogic JMS and Oracle AQ?
Any comments, references, documentation, sample code, url will be most welcomed :)
Thank you very much!

I wouldn't go as far to say Oracle AQ is out-dated today. However, it is indeed a proprietary technology that did not found much main-stream adoption in the earlier years after its introduction. The advent of JMS made it somewhat more useful (or should I say intriguing, because more people are trying to tie it together with other J2EE technologies), but the Oracle's JMS wrapper classes in aqapi.jar were not feature complete for a long while, so using it outside Oracle's application server was painful, if not impossible. I do agree that the info at the dev2dev's JMS newsgroup or in this forum is highly fragmented, as neither Oracle nor BEA provides an official solution to integrate AQ with WebLogic, so people like us have to learn the technology through experimentation and in a piecemeal fashion.
3 years ago I was literally "playing around" - we had a polling mechanism set up to use triggers to write Oracle data changes into an event table, and had a Java-based daemon to scan that table and publish events as JMS messages to the WebLogic JMS server. This continues to work reliably till today, but I was looking for a solution that has few parts - I wanted to hook up my WebLogic MDB directly to AQ as a foreign JMS provider. Although I was able to get it to work (including XA), there were a few hoops I had to jump through, such as decompiling the Oracle AQjms classes to make them bind to the WebLogic JNDI tree.
One year after that Diptanshu Parui took what I did a giant step further - he extended the Oracle AQjms classes to allow them to be bound to the WebLogic JNDI tree naturally, and he figured out how to use WebLogic JMS messging bridge to re-send single-threaded AQ JMS messages to clustered JMS queues, which allow concurrent message assumption by multiple instances of MDB's. My impression is that he is using that setup in a production environment.
I am sure you are aware of it but I would like to make it clear - in order to use AQ as a foreign JMS provider to WebLogic-hosted MDB's, you don't need to update your database to Oracle 10g - Oracle 8i is good enough (although I recommend at least 9i Release 2). It is not the database engine, but rather the aqapi.jar JMS wrapper on top of AQ that matters. I do recommend that you use aqapi.jar from Oracle Application Server 10.0.3 or up for better XA support, among other things. Again, you don't have to replace WebLogic with Oracle AS - you only need a single jar file from it and put it in your WebLogic's classpath. However, I don't know what this means from a licensing point of view if you ever go to production - do you have to pay the full price of OracleAS or OC4J just to use the aqapi.jar?
In the coming days I will test the latest aqapi.jar to see how much progress Oracle has made in terms of making their J2EE products more spec-compliant :-).
Hope the above gives you a different perspective.

Migrate a Single node clustered SQL SharePoint 2010 farm to an un-clustered single node SQL VM (VMware)

Silly as it sounds, we have a SQL2008r2 Clustered SharePoint farm with only one node. We did intend to have 2 nodes but due to costs and other projects taking priority it was left as is.
We have decided to virtualise the Database server (to be SQL2008r2 un-clustered) to take advantage of VMware H/A etc.
Our current setup is
    shareclus
= cluster (1 node – sharedb (SharePoint database server))
    shareapp1
= application server (LB)
    shareapp2
= application server (LB)
    shareweb1 = WFE (LB)
    shareweb2 = WFE (LB)
and would like to go to
    sharedb01vm = SharePoint Database server
    shareapp1
= application server (LB)
   shareapp2
= application server (LB)
    shareweb1 = WFE (LB)
    shareweb2 = WFE (LB)
So at the moment the database is referenced in Central Addministration as shareclus. If I break the cluster, shareclus will not exist so I don’t think I will be able to use aliases(?) but I’m not sure.
Can anyone help? Has anyone done this before? Any tips/advice to migrate or otherwise get the SQL DB virtualised would be greatly received.

I havent done this specifically with sharepoint, but I dont think it will be any different.
Basically you build the new VM with the name sharedb01vm. Now when you are doing the cut-over, ie when you are basically moving all the databases, you rename the servers.. ie the new VM will be renamed as Shareclus and the old cluster can be named anything
you like .
At this point the sharepoint server should point to the new VM where you have already migrated the db's.
Another option is to create a Alias in the sharepoint server "shareclus" to point to sharedb01vm.
I have seen both of this in different environments but I bascially dont prefer the Alias option as it creates confusion to people who dont know this.

Migrate a Single node clustered SharePoint 2010 farm to an un-clustered single node SQL VM (VMware)

Silly as it sounds, yes, we have a SQL2008r2 Clustered SharePoint farm with only one node. We did intend to have 2 nodes but due to costs and other projects taking priority it was left as is.

I’ve had a look around and seen the option to use SQL aliases but I’m not sure that’s the best option. I was thinking of rebuilding the DB server but was wondering if there is any other options
Has anyone done this before? Any tips/advice to migrate or otherwise get the SQL DB virtualised would be greatly received.

Hi, yes that's correct, but my query really is about the SharePoint side with regard to SharePoint and maybe using SQL aliases.
My current setup is
shareclus
   = cluster (1 node – sharedb (SharePoint database server))
shareapp1
= application server (LB)
shareapp2
= application server (LB)
shareweb1 = WFE (LB)
shareweb2 = WFE (LB)
and would like to go to
sharedb01vm = SharePoint Database server
shareapp1
= application server (LB)
shareapp2
= application server (LB)
shareweb1 = WFE (LB)
shareweb2 = WFE (LB)
So at the moment the database is referenced in CA as shareclus. If I break the cluster, shareclus will not exist so I don’t think I will be able to use aliases(?) but I’m not sure.
Can anyone help?

IPlanet 6.0 Servlet Engine with Weblogic 6.1 EJB engine

Does anyone have experience using iPlanet 6.0 Servlet engine with
WebLogic 6.1 EJB engine? The two engines will be located on separate
physical servers. If so, any information on the implementation would
be greatly appreciated (lessons learned especially). Would the cost
difference between using WebLogic's Servlet engine vs. iPlanet's
Servlet Engine be worth the attempt? I saw in some previous posts
that there were issues with how older versions of Weblogic RMI (T3)
Protocol worked and that Weblogic would only have one socket
connection for the iPlanet Servlet Engine through which all requests
will be multiplexed. This would be a bottleneck for any application.
Is this still true with the latest versions of these products?
Thanks,
Jon

WebLogic's Servlet engine is less than $1K / CPU I believe.

Castor with Weblogic 8.1 problem

Hi,
I am encountering problem using Castor with Weblogic 8.1.
I unmarshal XML files using Castor. My application works fine outside Weblogic,
but gives incorrect xml content when deployed.
My xml is like this :
<emrRoot>
<emrNode>
</emrNode>
</emrRoot>
When deployed in Weblogic, on parshing this document using Castor API, it shows
that there are 0 'emrNode' inside 'emrRoot'.
This is what the Weblogic parser is misinterpreting it as:
<?xml version="1.0" encoding="UTF-8"?>
<emr-root emr-node-count="0" emr-dynanode-count="0" valid="true"/>
Could someone pls help.
Thanks.
Regards,
Shafique.

Hi,
Generally this type of exception raised by a class or the serialization runtime when a class may not be serialized.The argument should be the name of the class.
You might be forgot to implement the serializable interface for the class in struts frame work.
check it properly.
