Help me in cluster

i have configured a cluster,
node a and node b in the island 1,all in the same machine,but have different server port,
when there is no sesionn,it works well,if one is down,and request is direct to another,but if i have session ,it also redirect to another node(if one down) but the session is wrong.
please help me,
here is my code in servlet
HttpSession session=request.getSession() ;
String scount=(String)session.getAttribute("counter");
int count=1;
if(scount==null)
session.setAttribute("counter","1");
else
count=Integer.parseInt(scount)+1;
session.setAttribute("counter",""+count);

If I understand it right , you dont see any log or stdout msg ? The only
          way to figure out whats happening seems like you need to do process
          monitoring.
          try using , 'tusc' to see what happens to the process on the hpux boxes.

  • Need Help Setting Up Cluster

    I'm a grad student in a lab that does a lot of bioinformatics computing. I am a bit more computer oriented than some of the others in the lab, and the PI (head professor) and another lab worker have turned to me to see if I can help them.
    They have told me that they followed the directions in the Apple manual for setting up the High Performance Computing and that they've gotten stuck at the same point after several attempts. They called a mac tech, but he only got them part of the way through and may not have used the correct settings on the changes he made.
    From what they've told me there is an external domain name that is used to reach the head node, which is also acting as a router, controller, open directory master, etc for all the compute nodes, and that the compute nodes are supposed to be on a private network with names in the form of stuff.cluster.private.
    First thing: I don't think the DNS settings are correct as typing in the recommended console commands to test the DNS setup (in the manual) resulted in a few weird errors.
    On the controller server, command "host cluster" returns the following error:
    Host cluster not found: 3(NXDOMAIN), though host cluster.private works, and the reverse host 192.168.0.1 works too.
    hostname returned the external name, which is inquiry.ccam.(my university's domain).edu
    On the node server that we have running, most of these commands result in an error:
    host: '.private' is not in legal name syntax (empty label)
    I'm not sure what this means, but it doesn't seem to be able to look up anything within the private domain.
    Secondarily, When a node is connected to an open directory master and working properly, should it's indicatory light be on or off? Right now, ours is off, but it is likely that the DNS problems are screwing up the open directory.
    Please help.

    I almost fixed the problem I was having before by adding the proper domain to the search option in system preferences -> network. However I still have an issue.
    I cannot get open directory/kerberos to work and as a result I cannot set up xgrid.
    Could this be related to the fact that the ip of the system is attached to an external hostname (which is causing the hostname that might needed by local services to be overridden). I cannot change the fact that the external hostname is going to point to the system, but I was thinking that a possible solution would be to add a server layer above the head node of the grid to act as a router and accept this IP address / hostname override and prevent it from mucking up the hostname of the head node. Is this a viable idea and is it even necessary?
    (This external domain name is a web-accessible site that is supposed to link in to a web service that will be provided by at least one of the servers on this grid setup, I'm not sure on the settings for that (it seems to work currently), but I'll worry about that when we get the rest of the system running.

    Please check whether your network supports IP multicasting. The default multicast host is 230.0.0.1. Check whether you can ping the server.
    Please follow the instructions in the Getting Started guide. Also you have to make your web apps distributable by adding tag in the web.xml. You can test your clustering by testing /servlet/SessionServlet supplied in the default-web-app

  • Error while creating cluster view

    Hi all,
    Requirement is to create cluster view copying cluster view VC_TABWU01  into custom view.
    CV VC_TABWU01 has two data base views V_T093C_10 and V_T093U_01 I copied them both in to ZT093U_01 and ZT093C_10 and created a CV Z_TABWU01. Field dependence is set, when I am activating view I am getting message that screen 300 of ZT093U_01 is modified. I changed all possible options as standard view, kindly help me activating cluster view.
    Error: The flow logic of the screen ZT093U_01 0300 is not that of a generated view maintenance list screen. Either the screen has been considerably modified manually, or the view which it is based on has no maintainable key.
    Thanks
    Krishna.

    Need to add events in TMG. Solved with help of standard CV

  • Upgrade from Solaris 8 SPARC with Sun cluster 3.1u3 to Solaris 10 SPARC

    Dear All,
    We are planning an upgrade of the OS from Solaris 8 SPARC to Solaris 10 SPARC on a two-node active-standby clustered system.
    The current major software we have on the Solaris 8 system are:
    1: Sun Cluster 3.1u3
    2: Oracle 9i 9.2.0.8
    3: Veritas File System Vxfs v4.0
    4: Sun Solaris 8 2/04 SPARC
    Any pointers as to what sequence and how the upgrade should be done?
    Thanks in advance.
    Regards,
    Ray

    yes I know it can be quite complicated and complex, but Sun provided us with a detailed documentation, at least in our case Solaris 9 to 10 it was very helpful.
    You might get better help in the cluster forum http://forums.sun.com/forum.jspa?forumID=842

  • Cluster and standalone

    we builted active/passive node windows server 2012 and sql server 2012 with shared storage data,log and backup.
    can we install standalone instances on active node and can we use the shared drives?
    please help me

    When the cluster fails over, the shared drives won't be available from the node and your standalone instance will not start. You can install the standalone SQL instance on the local drives but it might also create unnecessary complications during
    patching as patching entails upgrading the shared components of all SQL instances. Also, you would have to account for these standalone instances when setting SQL max memory such as you should consider the worst case when all instances are running on the same
    node along with standalone instances.

    A short answer would be that it is not recommended

  • HR: Tables stored in the subarea of a cluster

    Hi All,
    I would like to know the name of the tables stored in the subarea of a cluster. E.g. The tables stored in RX subarea of cluster PCL2.
    Will it be possible for me to get the details from the include RPCnxy00, where n - cluster number and xy- subarea in the cluster? Is there any other way of doing it?
    Thank you,
    Jayaprakash

    Hallo Jayaprakash,
    you could have a look at the function module PYXX_RESOLVE_RESULT_STRUCTURE. This will help with payroll cluster structures but don't forget that it's payroll specific.
    The method you suggest is a good start but unfortunately the RPCnxy00 "convention" is not one that was always strictly adhered to. It will generally work but not always. It would probably be safer to look at the import / export macros since all the tables and strings will be contained there.
    I hope this helps.
    Regards, Gerard.

  • Clustered role 'Cluster Group' has exceeded its failover threshold.

    Hello.
    I’m hoping to get some help with a cluster issue I’m having using Windows Storage Server 2012.
    When the cluster is created my Cluster Core Resources are all happy and online.
    I can more the Cluster Name using “move Core Cluster Resources” between the two nodes without any problems.
    If I select ‘Simulate Failure’ on the IP Address resource, it works the first time
    If I do it again shortly after it fails and I get an Event ID 1254, 1205 and 1069.
    Event ID 1254
    Clustered role 'Cluster Group' has exceeded its failover threshold. 
    It has exhausted the configured number of failover attempts within the failover period of time allotted to it and will be left in a failed state. 
    No additional attempts will be made to bring the role online or fail it over to another node in the cluster. 
    Please check the events associated with the failure.  After the issues causing the failure are resolved the role can be brought online manually or the cluster may attempt to bring it online again after the restart delay period.
    Event ID 1205
    The Cluster service failed to bring clustered service or application 'Cluster Group' completely online or offline. One or more resources may be in a failed state. This may impact the availability of the clustered service or application.
    Event ID 1069
    Cluster resource 'Cluster IP Address' of type 'IP Address' in clustered role 'Cluster Group' failed.
    Based on the failure policies for the resource and role, the cluster service may try to bring the resource online on this node or move the group to another node of the cluster and then restart it. 
    Check the resource and group state using Failover Cluster Manager or the Get-ClusterResource Windows PowerShell cmdlet.
    Basically I’m trying to simulate a network failure to make sure the failover kicks in.
    If I click on it and ‘Bring Online’ it comes up fine.
    Where do I find this Threshold Policy and set it to initiate failover if the IP Address resources fails?
    Thank you in advance for your help.

    Hi,
    The failover threshold is the number of times the group can fail over within the number of hours specified by the failover period. For example, if a group failover threshold is set to "5" and its failover period to "3," the clustering software stops attempting
    to bring the group online and leaves the resources within the group in their current state. For example, if the IP Address resource is brought online but the Network Name resource fails, the group is left offline, but the IP Address resource is left online.
    To configure thresholds for a resource:
    Right-click the cluster resource and then select 'Propereties'
    Click 'Advanced'
    Select 'Do not restart' if the cluster service should not attempt to restart. Restart is the default
    If 'Restart' is selected:
    Affect the Group: uncheck to prevent a failure of the selected resource from causing the Server group to failover
    Threshold: number of times the cluster service will attempt to restart the resource, and period is the amount of time in seconds between retries
    Do not modify the 'LooksAlive' and 'IsAlive' settings
    Unless necessary, do not alter the 'Pending Timeout'. This is the amount of time the resource is either in the online or pending or offline pending states before the the cluster service puts it in either offline or failed state
    For more information please refer to following MS articles:

  • Webconsole - shows nothing about cluster

    Hello,
    This is 2 node solaris 10 cluster.
    After changing the Service properties tcp_listen = true, I am able to access the 6789 port from other machine's browser (https://ip:6789)
    Now funny thing is when I click on Manage Sun Cluster application, it takes me to a page where it does not show any information, no status, blank frames.
    I'm uploading screen-shot here :http://i38.tinypic.com/2eol9o0.jpgI have tried from both the nodes, it does not work. What does work is zfs configuration. It shows status of pools and a lot of other information and seems like I can use it in future.
    Can anyone help me with Cluster Management with webconsole? Btw, cluster is working fine, verified with scstat (-g)..
    Please help,
    Thanks.

    Looks like it needs latest java, I updated java (jre) for windows and then it shows cluster page properly. I will now try updating jre on linux browser ..
    Thanks
    Btw, is there a way I will be able to restrict port 6789 to a particular IP in the network? I'm only using
    TCPwrappers and don't believe it is going to help here anyway.

  • Cluster-Aware Updating

    Cluster-Aware Updating
    i am reading about Cluster-Aware Updating and i installed on my hyper failover cluster .
    Till now i have some questions ....
    why should i use Cluster-Aware Updating although i have wsus installed in my enviroment ?????
    can we said Cluster-Aware Updating is replacment of WSUS ?
    i installed Cluster-Aware Updating but till now when i click on ( preview updates for this cluster ) i didnt anymore updates .
    please need help in this matter .
    thanks

    Hi Moonlight2000,
    Cluster-Aware Updating is not a replacement for WSUS: it's the feature that helps update all cluster nodes automatically - you need setting up updating just for the cluster itself, not for each of its nodes. Otherwise you would need to update each
    node one by one and it would be you who's responsible for updating each node exactly in the same manner as others.
    Regards,
    Michael
    Thanks for all your help
    but still have one issue :
    i installed Cluster-Aware Updating but till now when i click on ( preview updates for this cluster
    ) i didnt anymore updates .
    how can i ensure am installed CAU correctly ?
    how can i know from where CAU takes updates from wsus or Microsoft update ?
    thanks

  • How to find size of bundle?

    hi all,
    i am making a vi in which the input is a bundle containing unknown
    number of elements (string and double 1d and 2d arrays), i want to
    unbundle it and then write in matfile format, i need to know how many
    elements and the type of each element and then i can write them using a
    for loop and writing for each element.
    please give me suggestion how to do it and if somebody has any example please attach.
    thank you

    Hi,
    I'm not sure if you already have the cluster made or not... but an easy way to find and display what is inside, is to right click the cluster icon on the back panel > create > indicator.  This will automatically configure the indicator so that it dispalys everything correctly.
    Also if you need to see the elements individually, use the unbundle command.  Again to create indicators for each element of the unbundle, you can right click > create > indicator, like I have shown in the attached image.  This image demonstrates how to create an numeric indicator off of the array size module.
    Hope that helps.
