  • Active and backup weblogic cluster setup

    Env: wls10 MP1 running on RHEL 4/5.
    I want to setup a scheme where a weblogic application (clients connect thru ejb/t3 interface) is deployed on two independent weblogic clusters.
    I want to mark one cluster as active at a time and the backup cluster to take over when the active is down. This fail over need not be automatic (can be manual).
    Is setting up a proxy (for the 2 clusters )the right way to approach this ? Clients connect to the proxy address which can then decide which cluster to route to ?
    The client could probably use the cluster address as t3://cluster1Addr,cluster2Addr ?
    Thanx,

    I guess you need hardware loadbalalncer. I doubt you can acheive this federation with weblogic pre-built-in capabilities.

  • 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

    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,

  • BAM Cluster setup - issue with whole server migration configuration

    HI,
    We are working on a SOA , BAM , BPM Cluster setup on OEL VMs
    With Admin server running on Host1 and Soa_server1, BAM_server1 , Host2 - Soa_server2 , Bam_server2.
    We were successfully able to setup clustering for Soa without using the webTier utilities in our environment, Just by adding entries in the /etc/hosts file.
    Followed the document - except for web tier setup
    http://www.namredlek.nl/orasoa/InstallSOASuite11gOnCluster_v1.pdf
    1)     Installed Weblogic 11g.
    2)     Soa 11g.
    3)     Domain creation
    4) Configured Node manager
    5) Soa Clustering completed successfully.
    6) Domain up and running with SOA_Cluster up and running.
    7)     Extended the domain with BAM
    The issue revolves when we are doing teh Migration configurations from the console for BAM and we restart BAM server we get an error -
    Apr 14, 2011 2:30:35 AM weblogic.nodemanager.server.Handler handleStart
    WARNING: Exception while starting server 'bam_server1'
    java.io.IOException: Command '/oracle/Shared_MWHome/user_projects/domains/SOA_Domain/bin/server_migration/wlsifconfig.sh -addif eth0 192.168.1.6 255.255.255.0 ' returned an unsuccessful exit code '1'. Check NM logs for script output.
    and Bam server goes to Failed Not Restartable state.

    The error is clearly out there
    java.io.IOException: Command '/oracle/Shared_MWHome/user_projects/domains/SOA_Domain/bin/server_migration/wlsifconfig.sh -addif eth0 192.168.1.6 255.255.255.0 ' returned an unsuccessful exit code '1'. Check NM logs for script output.
    This error occurs due to a failure in adding the virtual IP of BAM server to the network interface you have specified in nodemanager.properties.
    You need to check whether you have specified the correct interface and subnet mask in node manager.properties as below :
    The fourth step is to edit the Node Manager's properties file. This file is called nodemanager.properties
    and is located in the ORACLE_BASE/product/osbmw/wlserver_10.3/common/nodemanager directory.
    For server migration to work properly, you need to add the properties listed below:
    Interface=eth0
    NetMask=255.255.255.0
    UseMACBroadcast=true
    · Interface
    This property specifies the interface name for the floating IP (for example, eth0).
    · NetMask
    This property specifies the net mask for the interface for the floating IP. The net mask should the
    same as the net mask on the interface; 255.255.255.0 is used as an example in this document.
    · UseMACBroadcast
    This property specifies whether or not to use a node's MAC address when sending ARP packets,
    that is, whether or not to use the -b flag in the arping command.

  • 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,

    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,

  • Slower in Weblogic cluster server than a single server

    I have an application in my development environment which is a single server of WebLogic 8.1 SP4. It is working fine in terms of performance.

  • Is Weblogic Cluster  supports Application scope Objects?

              Our Application is mainly depends on Application scope objects. On one m/c, it
              is perfect.
              Now, we want to support the failover , load balancing ... (High Availability).
              I know, weblogic cluster supports HttpSessions, EjbObjects ... etc. What about
              Application scope objects.
              we are planning for weblogic server which supports the our requirements.
              If not, what is the solution to make it work by using Weblogic server.
              for eg: I can give what type of application we are developing --- similar to
              textchat.
              our application is real time application.
              

    Even a singleton is not good enough as singletons are good only in the VM they were
              created it. One way is to have a distributed object such as a stateful session bean of
              which only one instance exists. U can create it at startup and store its handle in
              some persistent storage as well as a singleton. This ensures that even if the
              singleton doesnt contain it the refgerence to it can be obtained.
              There will be some problems with this setup as people should not allow it to create
              instances of it . Any such endeavor will lead to a CacheFullException.
              But essentially that seems possible.
              Even the 2.3 Servlet specification mandates that ServletContext and Application level
              object is only valid inside the JVM which created it. HttpSessions are replicated
              SessionContexts are not and are not likely to be in any J2EE application server

  • Weblogic cluster and routers

    Is it possible to setup a WLS cluster having two WLS boxes seperated by
              switches/routers ?
              - Bhupi
              

    Yes. you have to set you weblogic.cluster.multicastTTL greater than 1 in
              order to let multicast packages pass routers.
              However, it is not a good practice to set your cluster across LAN.
              Cheers - Wei

  • 2 node Webcenter Cluster setup

    Hi,
    I am trying to configure 2 node webcenter cluster, so far i was able to accomplish this:
    i) create 2 node weblogic cluster with webcenter [ WLS_Spaces1,WLS_Spaces2] , [WLS_Services1,WLS_Services2], [WLS_Portlet1,WLS_Portlet2]
    ii)configured the weblogic to Authenticate using AD, and configured Jive Admin to login using AD
    iii) configured JOC[java object cache] for webcenter spaces
    iv) and I am having issues configuring the WS-Security for spaces to acess discussion services.
    v) and also i am not able to see any policy store, and while trying to add a user to admin role for webcenter , i see it empty.
    in single node i am able to assign admin roles to users from AD with no issues.
    can some one help me in accomplishing the tasks for configuring the backend services of webcenter spaces when configured in cluster mode.
    Thank you
    A/
    * here is the doc link i am using for the setup

    We're running Server 2012 Data Center on the cluster nodes.
    I was thinking the same about the 3rd party software to do what I'd like it to do.   The data  is mostly security camera video from our security system.  Since its not really critical data, i'm just looking for a way to maximize
    the available hard drive space, and make it addressable as one volume or network share...

    You can build Storage Spaces (simple, not clustered as it would waste 50% of your capacity, MSFT can do mirror and parity with R2 for clustered only) from iSCSI LUs. Dog slow and unsupported but you'll have linear spanned space. See:
    Rough Guide To Setting Up A Scale-Out File Server
    http://www.aidanfinn.com/?p=13176
    Creating Virtual SoFS with shared VHDX
    http://www.aidanfinn.com/?p=15145
    you don;t need SoFS (obviously) but in this article Aidan creates Storage Spaces from iSCSI LUNs.
    Good luck!
    StarWind VSAN [Virtual SAN] clusters Hyper-V without SAS, Fibre Channel, SMB 3.0 or iSCSI, uses Ethernet to mirror internally mounted SATA disks between hosts.

  • Problems with weblogic clustering setup

    Hi all, I'm having problems extending a weblogic 9.2 cluster from vertical to orizontal. The environment is composed by two physical servers A and B. On A it's running the node manager, the admin console and two nodes, on B I've just installed weblogic 9.2, registered the licence.
    I'm reading this guide: http://egeneration.beasys.com/wls/docs103/cluster/setup.html#wp742559 but I think this guide is non clear.
    1) I added the new machine into the admin console
    2) I added the new server to the configuration (environmnent -> cluster)
    3) I created a new node on the new server and I associate it to the cluster and machine.
    moreover I checked the ports so that it should be set correctly.
    After I start the nodemanager into B and after adminconsole from A tries to connect to B I get this into the console

    should server A and B have the same domain configuration? (same files)
    Regards
    Marco

    Yes, you must have the same domain configuration on the server B. Usually I copy the domain directory on the server B to have the same configuration. the directory with "salt file" should be the "<domain_dir>/security"...
    Hope this helps...
