Clinet Application without joining the cluster

Hi All,
is it possible for client application to access the cache within a coherence cluster. The Client application is not a part of cluster and it didnt start with and cache config files or anything else.
The client application just uses :
NamedCache cache = CacheFactory.getCache("VirtualCache");
if a client application starts with a cache-config file it will also join the cluster in this case the JVM of the client app will aslo be loaded/distributed/replicated with the cache contents ?
Please clarify my doubts.
Regards
Srinivas.

The only clean way of NOT joining the cluster is to connect via Extend.
You can join the cluster, and specify LocalStorage=False parameter, however, that is only applicable for distributed cache. Replicated cache data still exists on every node. A bigger issue in my mind, is that your node will be actively managing membership of other members in the cluster, and that can become a problem.

  • Managed server not able to join the cluster

    Hi
    I have two storage node enabled coherence servers on two different machines.These two are able to form the cluster without any problem. I also have two Managed servers. When I start one, will join the cluster without any issue but when I start the fourth one which does not join the cluster. Only one Managed server joins the cluster. I am getting the following error.

    Hi,
    By default Coherence uses a multicast protocol to discover other nodes when forming a cluster. Since you are having difficulties in establishing a cluster via multicast, Can you please perform a multicast test and see if multicast is configured properly.
    http://wiki.tangosol.com/display/COH32UG/Multicast+Test
    Hope you are using same configuration files across the cluster members and all members of the cluster must specify the same cluster name in order to be allowed to join the cluster.
    <cluster-name system-property="tangosol.coherence.cluster";>xxx</cluster-name>
    I would suggest, try using the unicast-listener with the well-known-addresses instead of muticast-listener.
    http://wiki.tangosol.com/display/COH32UG/well-known-addresses
    Add similar entries like below in your tangosol override xml..
    <well-known-addresses>
    <socket-address id="1">
    <address> 172.23.34.91<;/address>
    <port>8190</port>
    </socket-address>
    <socket-address id="2">
    <address> 172.23.34.74<;/address>
    <port> 8090</port>
    </socket-address>
    </well-known-addresses>
    This list is used by all other nodes to find their way into the cluster without the use of multicast, thus at least one well known node must be running for other nodes to be able to join.
    Hope this helps!!
    Thanks,
    Ashok.

  • After patching the node, the node is not joining the cluster.

    Dear All,
    We are having a two node suncluster with below release

    And nodes are

    We are patching the nodes with 2q 2009 quarter patches, first we patched the node scrbdomderue005. we have followed the below step to patch the server.
    1) Our root d0 has d1(c0t0d0s0) and d2(c1t0d0s0)
    2) we have detached the d2 from d0; metaclear d2
    3) mount the c1t0d0s0 /mnt
    4) use the patchadd -R /mnt to patch the server. While patching we got only one error the patch 126106-27 need to be install in noncluster mode.
    5) switch the RG's from node scrbdomderue005 to scrbdomdfrm005.
    6) shutdown the scrbdomderue005, boot the scrbdomderue005 with c1t0d0s0 in noncluster-single user mode, and installed the patch 126106-27 and it was successful.
    7) shutdown the scrbdomderue005, boot the scrbdomderue005 with c1t0d0s0 in clustermode, and we are getting the following error.

    I could be because you have installed patch 138888. It has problems with nxge interfaces used as interconnect.

  • 11gR1 1 node won't join the cluster after reboot.

    This is a high level description of a problem.
    We usually run a two node cluster.
    This week we had an issue where one node needed to be taken down. It became non responsive and upon reboot the other node no longer functioned correctly.
    So one node was left running until the maintenance window.
    Apparently when it's brought back up it has the MAC of the second node in the arp cache.
    This leads to node1 not being able to join the cluster.
    I've seen workarounds that involve refreshing the arp cache but is there anything else to this?

  • Node failed to join the cluster because it ould not send and receive failure detection network messages

    One of my customers has a Windows Server 2008 R2 cluster for an Exchange 2010 Mailbox Database Availability Group.  Lately, they've been having problems with one of their nodes (the one node that is on a different subnet in a different datacenter) where
    their Exchange databases aren't replicating.  While looking into this issue it seems that the problem is the Network Manager isn't started because the cluster service is failing.  Since the issue seems to be with the cluster service, and not Exchange,
    I'm asking here. 
    When the cluster service starts, it appears to start working, but within a few minutes the following is logged in the system event log.
    FailoverClustering
    1572
    Critical
    Cluster Virtual Adapter
    Node 'nodename' failed to join the cluster because it could not send and receive failure detection network messages with other cluster nodes. ...
    It seems that the problem is with the 169.254 address on the cluster virtual adapter.  An entry in the cluster.log file says: Aborting connection because NetFT route to node nodename on virtual IP 169.254.1.44:~3343~ has failed to come up. 
    In my experience, you never have to mess with the cluster virtual adapter.  I'm not sure what happened here, but I doubt it has been modified.  I need the cluster to communicate with its other nodes on our routed 10. network.  I've never experienced
    this before and found little in my searches on the subject.  Any idea how I can fix this?
    Thanks,

    Hi,
    I suspected an issue with communication on UDP port 3343. Please confirm the set rules for port 3343 on all the nodes in firewall and enabled all connections for all the profiles
    in firewall on all the nodes are opened, or confirm the connectivity of all the node.
    Use ipconfig /flushdns to update all the node DNS register, then confirm the DNS in your DNS server entry is correct.

  • Node fails to join the cluster

    We are observing a problem where a node, after getting restarted, fails to join the cluster.
    We run two coherence clusters across three boxes. Each box runs 8 java processes, 4 processes of one cluster, another 4 process
    of the other cluster. They all run as windows NT services. Sometimes, some node goes down and gets restarted. But then it fails to join the cluster with following exception :
    "com.tangosol.net.RequestTimeoutException: Timeout during service start: ServiceInfo(Id=8, Name=DistributedFIIndicativeCacheWithPublishingCacheStore, Type=DistributedCache"
    Has anyone experienced and addressed such a problem? If required, I can provide exact details of the cluster setup.
    -Bharat

    Hi Bharat,
    This may be caused by a stuck or slow DistributedService thread on one of your nodes. Please log into http://support.oracle.com and take a look at [Note 845363.1|https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&id=845363.1] for more details. Additionally, consider upgrading to Coherence 3.5 as it includes the [Service Guardian for deadlock detection/resolution|http://blackbeanbag.net/wp/2009/07/20/coherence-3-5-service-guardian-deadlock-detection/].

    You mean take the cover off of the iPhone, to look inside?  I'd recommend against it.  Even with warranty expired, you might qualify for an out-of-warranty service, which for 3GS is $149.
    Other than that, any repair/service options are going to cost money.  You might want to see if a wireless carrier will let you get a new contract & phone.
    Out of curiousity, you're just using at as, basically, an iPod Touch, if there's no cell provider?  Did I understand that correctly?

  • Is there any way to log in to active directory from a mac without joining the AD domain?

    I am looking for a way to log in to active directory without having the Mac join the AD domain. Basically i have not been able to understand all the ramifications of joining the AD domain. From what I have read in various documentations on the apple site and some of the AD plug in sites, it seems that if the mac joins the domain, all kinds of group policies get 'transfered' to the mac experience. How exactly does that affect the privileges of the local mac user on their machine? do they need to change their mac password? what happens to their existing home directories? what happens when they have their laptops at home?
    TIA

    The reason i am hesitant about binding the macs is that i'm not sure what are all the effects of that. will they have to change their mac passwords / usernames? more than likely the auto login will have to go. If there are multiple accounts on the mac (ex one admin account and other regular and admin accounts) how does binding affect them? how will it work when the mac is not in the office? if they have admin rights on the mac but not on the windows AD, how will that affect them? Do you know of a source i could go to to find answers for questions like these?
    Unfortunately, the source for answers should be your IT department. I can tell you how my machine works. I have a personal machine with no restrictions and a work machine bound to an Active Directory domain. Even my work machine has few restrictions compared to normal. I have a privileged account I can use if necessary. Also, I'm pretty much a goody-two-shoes so I don't try to circumvent restrictions.
    Basically, the Mac uses a system called Open Directory to manage user accounts. Every Mac comes with its own miniature Open Directory server. If you have a network with MacOS X Server, you can use the server's Open Directory. You can also use Microsoft's Active Directory to perform all the same tasks. The user's logins and passwords would be whatever is on Active Directory. They can change their password on the Mac and it will change the Active Directory password. Active Directory can enforce passwords expirations too.
    I am not an Active Directory administrator, so I can't give you specifics. Pretty much everything you have mentioned can be controlled via Active Directory. That is what it is for. It does require active participation of your IT staff. If you don't have that, then I don't see it working out well. It sounds like a paradox. IT wants to control users, but doesn't want to deal with it. You can't have it both ways. Maybe let it be known among the Mac users that visiting those restricted sites could cause IT to get rid of Mac altogether. That does sound like a probable outcome.

  • Deploy simple Labview applications without installing the Labview runtime?

    [Labview 8.21 - Windows XP]
    Hello and a happy new year to all !
    I have coded very simple Labview applications that basically read text files (exported from Ms Excel), make some string operations, array sorting and at the end write another text file that is then imported in Ms Access. Now I would like other people from the School parents association to use this application on their own PC but ideally without having to install the Labview run-time;  for various reasons one of them being that they are not administrator of their PC, another reason being that I feel bad to ask them to install 100Mb of programs on their PC to execute my <1Mb applications. All that I can assume is that they have Excel and Access installed on their PC.
    I have read some postings on the Forum and in the Knowledge base from which I understand that the only way to use my application without the Labview runtime is to build a shared library that maybe I could then link via a VBA code from inside Excel or Access. But I cannot find any usable example on how to do that practically. And maybe it is not possible. 
    What is the easiest way to run such very simple Labview compiled applications on a PC that does not have Labview installed? Is Labview not at all built for such use?
    Thanks a lot for your help and ideas.
    Christophe

    You will need to have the runtime installed. There is a lot of other languages that also have the need for there own runtime, but they are commonly installed with the OS, so you don't realize it. Just building a dll won't solve this.
    There might be a hack possible, though. People have managed to strip down the required installation and been able to deploy the required parts of the runtime only. If you want to go this way, search on LAVA. But I'm not sure if it works with LV 8.20, and you will need to invest some time to figure out the minimum requirements. But be aware that it is a hack, so it's on your own risk.

  • How can i run external application without specifying the full path?

    for example, ms word executable file is winword.exe, but in java i am using the following command:
    Runtime.getRuntime().exec("\"C:\\Program Files\\Microsoft Office\\Office10\\winword.exe\");
    the thing is, i dont know where ms word is installed on every machine, so rather than making an assumption, do you know how i can run ms word without specifying the full path?
    thanks

    1) You could ask the user to tell you where it's at (and remember for next time)
    2) You could do a file search for it (and remember it for next time)

  • Can the node's UID be different when re-joining the cluster?

    Absolutely! The UID is the member's identity and if the cluster service restarts (within a given Java process), it will be always assigned a new and unique UID.

  • Migrating to Sharepoint 2013 from 2010 - Can you use the same URL for the Web Application without affecting the 2010 environment?

    Hi,
    I am currently trying to migrate our SharePoint 2010 environment to SharePoint 2013. The first thing I'm doing is creating a 2013 development environment to verify that this migration goes smoothly. I'm also doing this so that we will have a testing environment
    after the upgrade to 2013 is complete. 
    So here is my question: I have a 3 tier farm including; 1 app server, 1 wfe, and 1 sql server. I have made a copy of our SharePoint 2010 database and installed that on our sql server 2012 sever (This new environment is on 3 completely separate servers from
    our 2010 environment). I have also installed the prereqs and configured SharePoint 2013 on the App server and wfe servers, as well as configuring the necessary service applications (I have created a completely new 2013 database where I will migrate my 2010
    database content when I'm ready).
    I am now at the point where I need to create a new web application on the 2013 app server, where I will be migrating the copied 2010 database.  (Also note that we have a 2010 development site called https://[email protected])
    When I go to create a new web application in our 2013 dev environment, can I use the same url (https://[email protected]) to create this web app, or will this screw up our current 2010 dev environment?
    I'm new to SharePoint migrations, so I apologize if this is a stupid question.
    Thanks in advance for any insight you can share on this!

    So, what you are recommending is that before I create a web application in my new 2013 environment, I need go into my hosts file on my 2013 app server and alter it to point to my 2013 wfe.
    Then after I do that, then I can create my new web application on my 2013 app server with the same url as my 2010 testing environment
    (https://[email protected]). 
    Then after that I should be able to access my new sharepoint 2013 environment at the same URL (https://[email protected])?
    I must be missing something.
    In your first reply, you told me to alter the host file on my 2010 app server and point it to my 2010
    wfe (I guess I thought it probably already is). You also told me to alter the host file on my 2013 app server and point it to my 2013 wfe. 
    so I am confused on after I do this, what url would I access my 2010 test environment, and what url would
    I access my 2013 test environment?
    I am fine with having my test environment as a different URL until I am totally ready to roll everything over and kill the 2010 site. But I want to make sure that when I migrate my database, none of the site links are broken.
    I also want to make sure that if I proceed this way, I want to be sure that I will be able to modify the URL to what my 2010 environment is (without a lot of headaches) when I am ready to kill the 2010 site.
    Thanks again for your help, it's much appreciated!

  • Accessing an application without forcing the user to login

    I'm a new guy, so please forgive me if I don't have this quite right. I have an inquiry OAF application bolted on to apps R12 that I need to make available to users that do not have user IDs. They're all inside the firewall, so there are no issues with security as long as they can only access this single inquiry. Do I need to mount a separate OC4J server, or can this be done somehow with the existing apps OC4j server? Maybe based on the referring page or something? Can someone point me to anything that will get me started with this? Thanks.

    I found this topic in the forum which helps...

  • Pickup a class in application without bouncing the WLS

    Hi,
    I've an application(deployed on WLS) which basically takes the name of a class and delegates it to another process, which then loads the class and calls a few methods reflectively. For this, I want the second process to reference to a directory(outside the ear) so that it looks for the resolution in this directory.
    Now, the problem is, how to make the application refer to this directory. I do not want them to be loaded by server classloader as they will unnecessary be available to all other applications. So, adding the name to server classpath or deploying it as shared library is ruled out.
    Other requirement is, the jar file can be introduced dynamically by a user into the directory and the application should take care of it for any references. Bouncing application should do this needful.
    Does WLS have a feature to cater to this need?
    Thanks.

    hi thanks at first,
    the thing you mentioned could be a problem, but I dont think it is.
    If I have the full qualified name (which I havent) then everything goes normal. I only have to load the "twoButtons" class and not the other (actionadapter class), so I dont think this is the point. In this case the twoButtons constructor constructs an object of the actionadapter class and everything goes well. The bad thing is though that I do not have the full qulified name :(
    Invocation target exception tells me (in own words): Tried to acces the constructor of the actionadapter class (which is not public) out of class reflectionTest class .
    reflectionTest is the class where the reflection stuff happens and the twoButttons class is defineClass() ed.
    The problem is, only twoButtons class has the rights to call methods from the actionadapter class, the reflection class does not. BUT: I do not call the actionadapter methods from the reflection class. I call them only from the twoButtons class.
    I hope somebody understands my problem :)

  • Replicating a session to a server joining the cluster

    It is my understanding that session data is replicated only during calls to HttpSession.setAttribute() and HttpSession.removeAttribute(). If a user has established a session on server A (secondary on server B) and server B goes down, then an incomplete secondary is created on some other server. If server A fails before this user accidentally causes all of the session data to be replicated, then some requests to the new managed server will work and some will not creating eratic errors.
              

    Yes the replication behaviour in 6.x is different from 51
              "I believe that we "lazily" replicate sessions in 6.x - that is, until you
              access the session,
              it is not replicated.
              The reason for this is performance. Imagine if node1 had thousands of
              sessions when node2
              was down. If we did not do session replication lazily, then as soon as node2
              was viable, it
              would be flooded with thousands of requests to replicate the existing
              sessions. I believe this is
              the reason the change was made in the architecture between 5.1 and 6.x.
              There's always a trade-off. Some customers want performance and some
              customers want reliability.
              It looks like either we can choose the reliable behavior as same as WLS5.1
              does, or explain the "lazily"
              replication of HttpSessions in our edocs."
              If this behaviour is not acceptable for you, pls contact support and raise
              your voice.
              Also reference CR070084.
