SUNW.gds for jboss + Load Balancing Group = Failed to connect to host ...

Hi all!
In a simple two node cluster (Solaris cluster 3.2) with quorum server I've created a resource for jboss 5.1.0 using SUNW.gds. It is supposed to be load-balanced. To achieve that I've followed instructions from [http://download.oracle.com/docs/cd/E18728_01/html/821-1258/gds-25.html]
The command I've used to create the resource was:
clresource create -g scalable-rg -t SUNW.gds -p resource_dependencies=vip -p Scalable=TRUE -p Start_timeout=400 -p Stop_timeout=400 -p Probe_timeout=30 -p Port_list=8080/tcp -p Start_command="/opt/jboss-5.1.0.GA/bin/run.sh -b 0.0.0.0" -p Child_mon_level=0 -p Failover_enabled=TRUE -p Stop_signal=15 -p Load_balancing_policy=LB_STICKY_WILD jboss-rs
The whole configuration seems to work, but when the second node joins cluster, resource with jboss can't bind to shared ip address. There are many entries in /var/adm/messages like:

However, after some time, it finally somehow binds to shared ip and port 8080.
Is this something I should be worried about? Or it is a normal thing, since e.g. it takes some time to bring the interface with shared ip up? I've never had to install such configuration, and I don't have neither intuiton, nor the experience. Any help would be very appreciated.
Thanks a bunch,
Bart

Hi, a couple of things to check:
- did you check that both JBOSS instances were up and running?
- can you check in the logs (on both nodes) when a message saying something like "service .... registered..." showed up. This should show up for both JBOSS instances. From the time of the second "registered" message, the load balancer should sending incoming requests to both instances using its distribution mechanism
- did you check the vip address on one of the nodes on an external interface and on lo0 on the other
- connection refused looks like a server problem; can you connect to the JBOSS instance locally?

  • Forms Services availability checking for BIGIP Load Balancer

    We are load balancing across a number of 10.1.2.2 Forms servers using a BIGIP load balancer. Currently our load balancing is done based on which server has the "least connections" to the BIGIP. So far we have been using the following test URL to allow BIGIP to check the availability of the Forms Services on each server.
    http://server:port/forms/frmservlet?ifcmd=status
    This works well however it only checks through to the HTTP level within Forms Services. We encountered a problem when the Forms Services failed to work on a particular server however the above URL showed that everything was OK. The effect of this was that all new users attempting to login were directed to the failed server as this server had the "least number of connections".
    After raising an SR with Oracle they advised that the forking of runtime processes had probably failed and this was not detectable by the load balancer with the above URL. So they have recommended a number of options for checking the status of the Forms Services. These are:
    a) http://server:port/forms/frmservlet
    This loads the default Form and therefore by definition tests the forking of runtime processes. However BIGIP is unable to automatically process the information to distinguish whether the service is up or down. Oracle recommended that if using this method we would need to customise BIGIP to handle the various FRM-xxxx error codes.
    b) http://server:port/forms/frmservlet?userid=scott/tiger@YOURDB&form=yourtestform.
    fmx
    Even more thorough would be to actual log on to the database using a test form as above.
    My question is does anyone out there have experience in checking Forms Services availability using these last two methods as I'm not sure how to customize the load balancer so that it can handle the output of these URLs. Also when using the original URL is it normal to load balance using a "least connections" method or do people out there use a different algorithm.
    Thanks for any help/advise that you can give.
    Regards,
    Philippe

    Well SR followed up and it looks like the only course of action is to use the standard HTTP check: http://server:port/forms/frmservlet?ifcmd=status ...
    ... unless that is you want to do some serious customisation. Oracle don't support any other form of checking.
    I'm guessing from the lack of responses to this thread that this hasn't been an issue for anybody else ... ???
    Any thoughts/suggestions really welcome as we go into production in 4 weeks.
    a) What do people recommend for load balancing Forms ... least connection, round robin ... ?
    b) Do people use http://server:port/forms/frmservlet?ifcmd=status or have some of you used something else?
    Thanks,
    Philippe

  • Windows 7: Service unknown when using load balancing group

    I try to run SAP GUI 7.10 on Windows 7. I use a load balancing group to connect to the server. The direct access to one of our cluster nodes works ok, but when clicking the link to the load balancing group says "load balancing error on logon 88: connection to messaging server not possible (rc=9)" (translated from german).
    What is happening here? It works good on Windows XP. Do I have to use another saplogon.ini or something?
    Thanks for any help!

    Is it ok to deactivate UAC in a company?
    That's something your M$ group must decide.
    It sounds like a good security feature but as we see here it´s a pain in the @$$ for administrators...
    Well - the purpose of it is to disable the ability of malware and virusses spreading around. I consider it as a security breach if a local user is able to simply copy files to the operating systems main directory. A user working with a frontend PC should not have local administrator rights at all; all software requiring this badly designed.
    If you use the SAPGUI installation server you can distribute services, saplogon.ini etc. using the installation server provided service without the need of users having to have local administration rights:
    Note 512040 - Distributing "services", "saplogon.ini", and similar files.
    I just think that "administrators" must learn to do work properly as designed with operating systems without just "copying files around" in system directories (and I don't exclude me in that context).

  • Load-balancing and fail-over between web containers and EJB containers

    When web components and EJB components are run in different OC4J instances, can we achieve load-balancing and fail-over between web containers and EJB containers?
    null

    It looks like there is clustering, but not loadbalancing available for rmi
    from the rmi.xml configuration. The application will treat any ejbs on the
    cluster as one-to-one look-ups. Orion will go out and get the first ejb
    available on the cluster. See the docs on configuring rmi.xml (and also the
    note below).
    That is a kind-of failover, because if machine A goes down, and the
    myotherAejbs.jar are on machine B too, orion will go out and get the bean
    from machine B when it can't find machine A. But it doesn't go machine A
    then machine B for each remote instance of the bean. You could also specify
    the maximum number of instances of a bean, and as one machine gets "loaded",
    orion would go to the next available machine...but that's not really
    loadbalancing.
    That is, you can set up your web-apps with ejbs, but let all of the ejbs be
    remote="true" in the orion-application.xml file:
    <?xml version="1.0"?>
    <!DOCTYPE orion-application PUBLIC "-//Evermind//DTD J2EE Application
    runtime 1.2//EN" "http://www.orionserver.com/dtds/orion-application.dtd">
    <orion-application deployment-version="1.5.2">
    <ejb-module remote="true" path="myotherAejbs.jar" />
    <ejb-module remote="true" path="myotherBejbs.jar" />
    <ejb-module remote="true" path="myotherCejbs.jar" />
    &ltweb-module id="mysite" path="mysite.war" />
    ... other stuff ...
    </orion-application>In the rmi.xml you would define your clustering:
    <cluster host="230.0.0.1" id="123" password="123abc" port="9127"
    username="cluster-user" />
    Tag that is defined if the application is to be clustered. Used to set up
    a local multicast cluster. A username and password used for the servers to
    intercommunicate also needs to be specified.
    host - The multicast host/ip to transmit and receive cluster data on. The
    default is 230.0.0.1.
    id - The id (number) of this cluster node to identify itself with in the
    cluster. The default is based on local machine IP.
    password - The password configured for cluster access. Needs to match that
    of the other nodes in the cluster.
    port - The port to transmit and receive cluster data on. The default is
    9127.
    username - The username configured for cluster access. Needs to match that
    of the other nodes in the cluster.

  • GSS act as an authoritative DNS for non-load balanced sites?

    I have a client asking if a GSS can be the authoritative DNS server for their entire domain.  This would include sites that are not load balanced.
    TIA,
    Dan

    Hi Dan,
    Yes, you would just have to create a new domain under the Domain Lists, create an Answer Group associated to that domain and then you can start adding DNS answers. For non-load balanced sites you would just have one answer in your answer group.
    Sincerely,
    Kyle

              , there's no exception
              but load balancing does not happen. According to the document , there's must load

                   DBStateful the_ejb2 = (DBStateful) PortableRemoteObject.narrow(home.create(3),

  • Best way for HTTP load balancing in OSB

    Hi everybody,
    We have setup an OSB cluster and we need to load balance HTTP requests across managed servers. Looking for info about load balancing in OSB I found that there are mainly two options: using a hardware load balancer or a software solution like Weblogic HttpClusterServlet. At the moment we have no hardware balancer available so we will have to take the software option. I found some articles about configuring HttpClusterServlet like http://redstack.wordpress.com/2010/12/20/using-weblogic-as-a-load-balancer.
    But I have a question about this configuration. If we use a managed server as an HTTP proxy that balances requests between OSB managed servers, what would happen if this server goes down? I think one of the main goals of a clustered deployment is avoiding a single point of failure but with that setup all requests would depend on the availability of the proxy managed server.
    Could you recommend us a setup for implementing load balancing in OSB?
    Thank you in advance,
    Daniel.

    Load balancing in a cluster for http requests can be achieved using atleast 4 different ways:
    (1)- use a hardware load balancer like F5 BigIP LTM
    (2)- use a web server with weblogic plugin to frontend the cluster
    (3)- use weblogic with HTTPClusterServlet
    (4)- use DNS round robin - this works if you have managed servers running on 2 machines (say mach1, mach2) but on the same port. HTTP clients use hostname 'mach' to access the URL's and the dns does a round robin name resolution of mach to mach 1 and mach2 IP addresses..
    All the options except (1) achieve only load balancing and not auto failover on all instances.. Hardware load balancers has the extra feature of probing [ sending periodic pings to the targets] , by which it can detect whether the target resource is alive and if not send the traffic to other nodes which are alive.. this is why hardware load balancers are worth their investment..
    other options may work if client is coded to do retrying on failure.. so on 2nd or subsequent attempt, the routing is done to the machine which is alive..
    For options (1),(2) and (3), you also need some redundancy of load balancing device ( web server, weblogic or hardware load balancer) to prevent single point of failure.. Hardware load balancers are usually deployed in redundant pairs to achieve this..

  • CSS11000 Load Balance over two VPN connections?

    Is it possible to have a CSS11000 in a local site perform load balancing and fail over to two different destinations on the internet that require a VPN connection. The VPN will be a router to router VPN using 7206s.

    Hello Bruce !
    CSS is designed to handle TCP- and UDP based traffic, not IPSec. When handling IPSec traffic Content Switching Module (CSM) inside Catalyst 6500 series is recommended for that purpose.

  • Load balancing error 88: Cannot connect to message server (rc=9)

    Hi,
    We are facing a problem in the system object.
    initially we created a system object with loadbalancing template ,and everything worked fine, but after couple of months we found a error "Load balancing error 88: Cannot connect to message server (rc=9)", so we have created a Dedicated application server object which resolved our issue.
    My question is why has this problem occured, and since my client side has lot number of users and we wish to keep the system back to load balancing object.
    How can i make my system object work back, what might be the causes?
    Thanks
    Srivastsa Kondapally

    Load balancing only works if the message server is available and the logon group specified exists as well.  If one of those changes, then it will break until you get the values set correctly.

  • Azure: "Cloud Services" for VM - Load Balancing, yes, and other things?

    I'm trying to get a handle on the significance of the cloud service
    (that is created when a new VM is created). I understand that a group of
    VMs need to belong to the same cloud service in order to participate in
    Load Balancing. I can't see any other reason to group VMs into a single
    Cloud Service. On the other hand it seems like overkill to create a
    cloud service for each VM.
    Are there any advantages/reasons to adding a group of VMs to Cloud Service other than Load Balancing?

    Hi,
    If you made a group VMs as a cloud service, you can configure them and manage them by yourself, you could select Linux or Windows Server VMs and either compose the VM images in the cloud or upload a VHD you’re previously
    created using Hyper-V, You can capture a VM and add it your image gallery for easy reuse. you also could run a product like Active Directory or SQL Server or SharePoint Server successfully, etc...
    I suggest you have a look at following article. (create VM as cloud service belong to IaaS)

    Hi MS DEF,
    A second network adapter is required to provide peer-to-peer communication between cluster hosts. Please isolate your heartbeat network. With unicast when cluster is connected
    to a switch, incoming packets are sent to all the ports on the switch, which can cause switch flooding, please confirm you have setup your switch correct, you can refer the following Cisco Switch related unicast configuration.

  • Not able to find mod_oc4j.conf file for setting Load Balancing on ESB

    Hi Guys,
    I am trying to set load balancing on ESB ,I got one document from oracle site for setting the load balancing on ESB. According to that document we have to change mod_oc4j.conf file for setting the roundrobin:weighted,metric,random algorithms.
    But I am not able to find mod_oc4j.conf file in my ORACLE_HOME directory.
    Actual path is
    ORACLE_HOME/Apache/Apache/conf/mod_oc4j.conf file
    I have All folders up to conf but in conf folder there is no mod_oc4j.conf file.
    I just want to know is there any installation problem or we have to create
    mod_oc4j.conf file in that conf folder for seting the loadbalancing on ESB
    kindly give me the exact solution on this .
    Thanks in advance

    Hi Chintan,
    I have apache folder ,but there i have cong folder but in that I am not able to find mod_oc4j ,I know ESB it maintain load in transparent way but in my project we have heavy load on ESB we have to maintain this load in a proper way
    Please give me the exact solution to set load balancing On ESB.
    Thank you

  • Geting IP address for Internal Load Balancer

    I've recently been experimenting with internal load balancing for VMs. I'm able to create and delete an internal load balancer (ILB) using the .NET wrapper for the API (https://github.com/Azure/azure-sdk-for-net).  What I cannot do though is actually
    get the internal address for it. Nor does it seem you can get it from the REST API (which, as far as I know, is what .NET wrapper wraps).   The only method I can see that claims to get the address is Powershell.
    Can anyone confirm if there is any way using the REST API or its .NET wrapper to obtain the internal address for the ILB?

    I have not looked into the .NET wrapper that you mentioned here, but according to this powershell script:
    http://msdn.microsoft.com/en-us/library/azure/dn690125.aspx
    $svc="<Cloud Service Name>"
    $ilb="<Name of your ILB instance>"
    $subnet="<Name of the subnet within your virtual network-optional>"
    $IP="<The IPv4 address to use on the subnet-optional>"
    Add-AzureInternalLoadBalancer -ServiceName $svc -InternalLoadBalancerName $ilb –SubnetName $subnet –StaticVNetIPAddress $IP
    IP address is optional, so maybe the wrapper hasn't implemented this, which is kind of undesirable. But maybe it allows you to specify the IP?

  • Question on WCCPv2 - bucket assignment for WCCP2 load balancing

    Hello,
    I would like to know if any one has tried out running Cisco's WAAS/WAFS/WAE or
    Squid proxy as a cache cluster to leverage load balancing support in WCCPv2.
    I am trying to understand WCCP based transparent network redirection in a lab setup using squid cache's WCCP and Cisco routers only. When I tried with 2 proxies for load balancing, I see that the router *always* allocates buckets in the reverse order of the specified assignment - its confusing as its not mentioned in Cisco WCCP2 protocol drafts.
    In my case, the lead cache with the lowest IP specifies buckets 0-127 to itself and 128-255 to the other; but the router assigns buckets 0-127 to the second cache and 128-255 to lead cache.
    I have attached the ethereal trace. Can someone explain what is going wrong here?
    The issue was found in the following router versions:
    Cisco 3600, IOS 12.3(1a);
    Cisco 2600 IOS 12.3(9a);
    Cisco 2800 IOS 12.4(3d)
    Squid proxy:
    2.5
    WCCP status output - all the routers above show the same behavior.
    From the trace, 192,168.8.231 specifies bucket distribution as its the
    lead cache with a lower IP than 192.168.41.232.

    I'm not an expert of the details of wccp, but looks like the squid is not setting the bucket info correctly.
    From the draft [below], the first bit is the the A flag - for alternative hashing.
    And the alternative hashing is determined by another flag in the service info.
    So, why is Squid setting this bit ?
    I feel like they forgot to shift the index by 1 bit to the left.
    Bucket 0-255
    Contents of the Redirection Hash Table. The content of each bucket is a
    web-cache index value in the range 0-31. If set the A flag indicates
    that alternative hashing should be used for this web-cache. The value
    0xFF indicates no web-cache has been assigned to the bucket.
    0 1 2 3 4 5 6 7
    +-+-+-+-+-+-+-+-+
    | Index |A|
    +-+-+-+-+-+-+-+-+
    I'm double checking with a developpers for our cache, but I feel like this is the explanation.
    More info to come if I'm wrong.
