CSM not load-balancing properly

Folks,
I'm seeing that CSM is not loadbalancing properly to all the servers in the serverfarm.
I simulated a failover of one of the servers TS05 and brought it back. After coming online, CSM sent no traffic to that server, as shown below:

Folks - I upgraded the code to 4.2(6) and thought that bug CSCei26434 was solved, but still see the same error where CSM is not balancing properly.

  • Cluster not load-balancing, ideas?

    I've been struggling to identify why my JMS producers are not load-balancing against a remote cluster.
              I've ruled out the producer as being the problem (I see the same non-load-balancing behavior regardless of what I use to create messages - Hermes, ALSB, simple Java producer...) I also don't think the JMS Connection Factory config is the problem, judging by the help I've received from folks over on the jms forum.
              I believe something is wrong with our cluster setup because in addition to the problem I just mentioned, we also are not seeing JNDI entries propagate to all managed servers - for example, if I create one jms queue on m1, that queue does not appear in the jndi tree on m2.
              I've been trying to find any documentation on what settings I should look at to verify the cluster configuration. If I go through the WLS console and look at the Cluster settings, I see both managed servers there, is there some other place that the configuration could be messed up?
              Added 6/11, 9:30 am:
              We're focusing on multicast now as the most likely problem. Can anyone tell me whether clusters on the same multicast address but different ports will interfere with each other? It looks like the infrastructure team has set up 5 clusters like that (same multicast address in each cluster, but different ports).
              We've got a ticket open with BEA but it's been two weeks now and nothing except requests for more information.
              Any ideas/help are much appreciated!

              You could be right. I think we have had problems where the same IP but
              different ports were used for multicast. This is on 8.1 though.
              I think as a rule, it's best to have a different ip and port for each
              cluster.
              Also - can you be sure that no one else is using the multicast addresses
              on the network for anything else - we had someone bring up a test
              cluster using our addresses which caused a few issues and took a while
              to find! We also have security cameras which also use multicast, which
              if they are using the same address/port can cause issues!
              We're using 239.192.1.4:8001 for one cluster and 239.192.1.3:7001 for
              the other - I think it's best to keep those as different as you can.
              In 8.1, there is also the multicast monitor utility - there's a support
              pattern on e-support on how to diagnose it. I've found this useful in
              the past when I've suspected a cluster issue.
              https://support.bea.com/application_content/product_portlets/support_patterns/wls/MulticastErrorsPattern.html
              Check also that you're using a valid range for the address - we weren't
              for a while and had odd problems from time to time.
              There are also cluster debug flags available which you'll see listed in
              the support document.
              Are you seeing dropped multicast packets?
              Hope that helps.
              Pete

  • CSM L7 LOAD BALANCING

    I need to load-balance trafic with a persistence based on http header "X-Nokia-MSISDN".
    Knowing that I'm using the version 4.1(6), the command "http header sticky" is not available (version 4.2 and more).
    I've seen that the following command is available "persistent rebalance" with version 4.1(6) but I'm not sure about what is its action.
    According to the definition given in the guide (
    "The CSM allows HTTP connections to be switched based on (...) fields contained in the HTTP header."
    MY QUESTION :
    How can you define that persistence should occurs on the "X-Nokia-MSISDN"
    http header ?
    Thanks for your help
    Francois

    the persistent rebalance command tells the CSM to look at every HTTP request to select the best server. So, if you have a persistent connection ( 1 tcp connection for many http requests ), the CSM will look at each request.
    Otherwise, it only looks at the first request and assumes all the other requests stick to the same server. Which is normally true, except if you have a proxy connecting to your vserver.
    You still need 4.2.x to allow sticky on header info.
    Gilles.

  • Using CSM to load-balance two sites

    Hi there,
    I currently use CSS11500's at two of my sites and I'm able to use source-groups to achieve site load-balancing behind a single VIP.  So basically I have a VIP that has servers in both the local site and remote site.   Is something like this possible with the CSM? I suppose there's the nat server or nat client commands, but I'd like to be able to maintain original client IP address if possible, or at least maintain the original client IP for connections that stay local to the site.
    Thanks,
    Brandon

    Hello Brandon-
    It is not directly possible to pick and choose what servers are natted on the CSM like the CSS and ACE can do.
    In the CSM, you configure nat under the serverfarm specifically.
    Ex.
    serverfarm Client_Nat_Example
    nat server
    nat client REMOTENAT
    real 10.10.10.1
      inservice
    natpool REMOTENAT 172.16.35.5 172.16.35.5 netmask 255.255.255.0
    If you were to devide up the traffic prior to hitting a serverfarm (maybe use a policy that matches specific subnets for your clients), then you could nat to only certain servers.
    Ex.
    access-list 2 permit 5.5.0.0 0.0.255.255
    serverfarm Client-Nat-Example
    nat server
    nat client REMOTENAT
    real 10.10.10.1
      inservice
    serverfarm No_Nat
    nat server
    no nat client
    real 20.20.20.1
      inservice
    natpool REMOTENAT 172.16.35.5 172.16.35.5 netmask 255.255.255.0
    policy client_remote
    serverfarm Client_Nat_Example
    client-group 2
    vserver HTTP
      virtual  172.16.35.7 tcp www
      slb-policy client_remote
      serverfarm No_Nat
      persistent rebalance
      inservice
    With this config, the CSM checks global access list 2, anything that matches a source of 5.5.x.x subnet would go to the serverfarm with the remote servers. Anything that does not match 5.5.x.x would use the default serverfarm under the vip (No_Nat serverfarm).  This is not optimal, but there is no parity between CSM and CSS when it comes to per-server NAT.

  • Clustering not Load balancing on solaris with apache

    apache weblogic plugin does not do round-robin , it's kind of random when
              direct the request to the appserver. anyone has seen this problem?
              weblogic5.1 sp9. solaris 2.7 jre1.3.1 rc2
              

    Actually, the random load-balancing when using Apache is caused by the fact
              that Apache (<2.0) spawns multiple processes, so single Apache instance
              will have several plug-in instances running.

  • Load Balancing not load balancing!

    Hi,
    We have inherited a 6.3 2005 Q1 installation of Access Manager that has the following problem.
    All logons appear to be load balanced correctly however all Policy Agent requests are expressing a preference for one or other node at a time.
    For example, during the last 4 days all PA traffic has been hitting Srv01. This leads to an 80/20 balance. This morning on Srv01 an error in the amSession logs appeared on Srv01, "SessionRequestHandler NullPointerException" and from this point on Srv02 started to take the Policy Agent requests. So now the traffic is still 80/20 but wth Srv02 handling the 'lion's share'.
    Can anyone point me to documentation that describes in detail how Load Balancing working in the products?
    Thanks,
    EddieT

    Hi,
    Sorry I should have been more specific. The error we are seeing has been reported before but no resolution posted.
    Thanks.

  • Safari not loading page properly

    Hi all,
    I have a fairly specific problem with Safari (8.0.3 on OS X 10.10.2) in that the Stripe login page does not load properly for me. All I see when I go here is basic HTML: http://dashboard.stripe.com/login
    In terms of troubleshooting, I have tried the following
    Disabled Extensions
    Disabled plugins
    Emptied Caches
    Cleared cookies and other website data
    I then decided to create a new user on my Mac to see what would happen. In the new user's Safari, the page loads exactly as it should.
    So, my question is, what else can I do to troubleshoot this? Have I missed something?
    Cheers,
    Pete

    Back up all data before proceeding.
    Quit Safari if it’s running. Then select
               ▹ Force Quit…
    from the menu bar. A small window will open with a list of running applications. Safari may appear in that list, even though you quit it. If so, select it and press return. Close the window.
    Step 1
    Hold down the option key and select
              Go ▹ Library
    from the Finder menu bar. Delete the following items from the Library folder (some may not exist):
              Caches/com.apple.Safari
              Caches/com.apple.Safari.SearchHelper
              Caches/com.apple.SafariServices
              Caches/com.apple.WebKit.PluginProcess
              Caches/com.apple.WebProcess
              Caches/Metadata/Safari
              Preferences/com.apple.WebKit.PluginHost.plist
              Preferences/com.apple.WebKit.PluginProcess.plist
              Saved Application State/com.apple.Safari.savedState
    Leave the Library folder open. Try Safari again. If the problem is solved, stop here. Close the Library folder. If you still have a problem, continue.
    Step 2
    Restart the computer in safe mode. Certain caches maintained by the system will be rebuilt.
    Safe mode is much slower to start up than normal.
    When the login screen appears, restart as usual (not in safe mode) and test. There's no need to log in while in safe mode.
    Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t start in safe mode. In that case, ask for instructions.
    Step 3
    If Safari still doesn’t work, quit, go back to the Finder, and move the following items from the open Library folder to the Desktop (again, some may not exist):
              Cookies/Cookies.binarycookies
              Internet Plug-Ins
              Preferences/ByHost/com.apple.Safari.*.plist
              Preferences/com.apple.Safari.Extensions.plist
              Preferences/com.apple.Safari.LSSharedFileList.plist
              Preferences/com.apple.Safari.plist
              Preferences/com.apple.WebFoundation.plist
              PubSub/Database
              Safari
              SyncedPreferences/com.apple.Safari.plist
    Here, "*" stands for a long string of letters, numbers, and dashes.
    Note 1: You are not moving the Safari application. You’re moving a folder named “Safari.”
    Note 2: This step will remove your Safari extensions, if any, and their settings. If you choose to reinstall them, do so one at a time, testing each time to make sure you haven’t restored the problem.
    Try again. Your settings and bookmarks will be lost. The default set of bookmarks will be restored. Delete them all.
    If Safari is now working normally (apart from the lost settings), look inside the “Safari” folder on the Desktop for a file named “Bookmarks.plist”. Select
              File ▹ Import Bookmarks...
    from the Safari menu bar. Import from that file. Recreate the rest of your Safari settings. You can then delete the items you moved to the Desktop.
    If the issue is still not resolved, quit Safari again and put all the items you moved to the Desktop back where they were, overwriting the newer ones that may have been created in their place. You don’t need to replace the files you deleted in Step 1. Stop here and post again.

    Our db is 2 nodes RAC with version of 10.2.0.3.0 on window 2003 server. I am wondering what else we may need to look into besides tnsnames.ora file to well balance the load between those two instances. Currently our
    db is not well balanced based on the following two things:
    1) query against gv$session
    2) different amount of archive log files created in those two servers
    Any help is greatly appreciated.
    Shirley

    1) query against gv$sessionMay be check the load on the individual servers as well and check to make sure that the LOCAL_LISTENER and REMOTE_LISTENER parameters are set correctly.
    2) different amount of archive log files created in those two serversI don't think measuring this would be a valid metric to evaluate the effectiveness of load balancing and this is not taken into consideration by oracle while load balacing the connections....

  • Safari browser not loading videos properly?

    Every time I use Safari to load videos or go on YouTube, the video either does not load properly and gives me an error message "your browser does not currently recognize this format" or it says HTML5 and I have to click on it for it to load. The message usually goes away when I refresh the browser and the HTML5 message will appear. The video usually works after I click on it, however the video doesn't play in YouTube's video player. It's just really inconvenient not being able to use YouTube's video player or even other video players on different websites. I was wondering is there anything I can do to fix this, or this just the way Safari loads videos?
    I've attached some images showing the issues.
    Thanks for any help!

  • ACE module not load balancing across two servers

    We are seeing an issue in a context on one of our load balancers where an application doesn't appear to be load balancing correctly across the two real servers.  At various times the application team is seeing active connections on only one real server.  They see no connection attempts on the other server.  The ACE sees both servers as up and active within the serverfarm.  However, a show serverfarm confirms that the load balancer sees current connections only going to one of the servers.  The issue is fixed by restarting the application on the server that is not receiving any connections.  However, it reappears again.  And which server experiences the issue moves back and forth between the two real servers, so it is not limited to just one of the servers.
    The application vendor wants to know why the load balancer is periodically not sending traffic to one of the servers.  I'm kind of curious myself.  Does anyone have some tips on where we can look next to isolate the cause?
    We're running A2(3.3).  The ACE module was upgraded to that version of code on a Friday, and this issue started the following Monday.  The ACE has 28 contexts configured, and this one context is the only one reporting any issues since the upgrade.
    Here are the show serverfarm statistics as of today:
    ACE# show serverfarm farma-8000
    serverfarm     : farma-8000, type: HOST
    total rservers : 2
                                                    ----------connections-----------
           real                  weight state        current    total      failures
       ---+---------------------+------+------------+----------+----------+---------
       rserver: server#1
           x.x.x.20:8000      8      OPERATIONAL  0          186617     3839
       rserver: server#2
           x.x.x.21:8000      8      OPERATIONAL  67         83513      1754

    Are you enabling sticky feature? What kind of predictor are you using?
    If sticky feature is enabled and one rserver goes down, traffic will leans to one side.
    Even after the rserver retuns to up, traffic may continue to lean due to sticky feature.
    The behavior seems to depend on the configuration.
    So, please let me know a part of configuration?

    Yuji

  • WLS 8.1.4 cluster is does not load balance correctly

    my cluster runs on 2 separate machines..
    any ideas? problem with DNS maybe?
    thanks

    Hi,
    Go through the following link and check whether you configured load balancing settings correctly or not.

  • Firefox is not loading websites properly on our mac.

    Firefox is not loading banners/background images/various interactive buttons etc on '''all''' web sites: I'm using Firefox/3.6.12 on Mac OS 10.4.11
    Other browsers are fine: ie Safari and Opera.
    Firefox is working fine on our PC.
    I have taken screen shots of Google home page and Firefox home page in Ff and Safari to illustrate this point and can email these to you so you can see what's happening. Ff was working fine yesterday.
    Entering extra information as requested I've noticed that the Default Plugin is showing as disabled in the Technical info under the Trouble shooting menu but is showing as enabled in the plugins list in the Ff drop down.

  • WLS proxy plugin does not load balance

    I have a cluster created with two app servers in separate boxes and a Weblogic proxy plug-in to forward the client requests to the servers. However, the proxy doesn't distribute the load equally. Very often 90% of the user sessions go to one server and 10% to the other. Both boxes have the same hardware specs.
              Does the WLS plugin really support round-robin load balancing ? I'd appreciate any information to solve this problem.
              Thanks
              - Miguel
              I'm using WLS 6.1 SP2.
              

    Are you load balancing the web servers? What kind of web servers are you
              using?

  • Plugin Checker Not Loading/Checking Properly

    Today I tried to check my plugins to see if they were up to date, as one should do on a regular basis in order to keep things running smoothly.
    However, when I tried to check, all I got was this: http://i.imgur.com/gI1rlqH.png The page would complete loading, but the plugin information would not load.
    I manually checked the plugins I frequently use, and all are up to date...so I doubt that is the cause.
    My Firefox version is more or less up to date...so that's probably not the cause either.
    I checked the page while in Safe Mode; that did not get me any results. The issue was still there. So that's probably not the problem either.
    I doubt internet connection is an issue too, as my internet is fairly good and usually this page loads no matter the signal strength.
    I have not done anything new to either my laptop or the browser, so I am wondering what is causing the Plugin Checker to not load the way it should.

    @philipp I just tried your suggestion. No luck there, even after restarting my browser.
    Also, it appears I am not the only one with this issue. I just spotted another thread describing the same issue.

  • Netboot servers not load balancing

    We have 2 netboot servers that have been happily load balancing eachother for about a year ( 10.5.4, diskless netbooting, everything works fine, know about index numbers, etc). Recently, I replaced one of those servers with a new machine. Now, basically all the netboot clients boot to the new server. I have tried deleting the client files on the old server ( it was in the 7000s) as well as /var/bsdp_clients file to try to get my old server to reset its client numbers to zero ( I am convinced that they won't start load balancing again until the client numbers match up, I have seen this before). The occasional new client that boots to my old server will create a shadowfile numbered in the 7000s.
    Anyone have any ideas?
