SharePoint Service Load Balancing

Hi,
I used to install small farm with all services on one App Server. I have question about having multiple App Servers.
Can we install/start same the service on multiple app server for redundancy ? If so, how the load balancing is managed ?
If that true for all services (Search, Excel...)
Thank you

The Topology Service uses Round Robin.

  • A question about the SharePoint services load balancer

    Let's consider a farm with one WFE and two app servers, A and B. Both app servers are running the Managed Metadata Service (MMS). 
    User requests a page from the WFE, which talks to the database server. The operation needs information from the MMS, so the WFE requests information from the round robin load balancer for SharePoint web services. Let's say server A is down. 
    Here's my question - what happens next?
    a) The round robin load balancer tells the WFE the MMS is on servers A & B. The WFE tries server A, fails, and returns a failure. 
    b) The round robin returns servers A & B. The WFE tries server A, which fails. The WFE then tries server B.
    c) The round robin returns either A or B, depending on which is next in rotation. The WFE tries the server returned. If the server returned is A, the WFE returns a failure. 
    d) The round robin returns either A or B, depending on which is next in rotation. The WFE tries the server returned. If the server returned is A, the WFE queries the round robin service again.
    e) The round robin knows server A is down, returns only server B to the WFE.

    Business Intelligence Solutions

    When a Service Application is down, the application load balancer removes that endpoint from the load balancer. When it becomes available again, it adds it back. This way the WFE would just contact the MMS endpoint that was available, not try and timeout
    against an unavailable endpoint.

  • Web Services Round Robin Service Load Balancer Event Endpoint Failure

    I keep seeing these errors in the UlsTraceLogs:
    SharePoint Web Services Round Robin Service Load Balancer Event: EndpointFailure Process Name: OWSTIMER Process ID: 3748 AppDomain Name: DefaultDomain AppDomain ID: 1 Service Application Uri: urn:schemas-microsoft-com:sharepoint:service:9b3095eda69947b299d2f873bbfee5ad#authority=urn:uuid:a01381a61b244525ab4fec30cde9dc5f&authority=https://ApplicationServerName:port/Topology/topology.svc

    what do these errors mean?

    ok, thanks, I'll have a look at that.
    Going back to my issue...  Since I stopped the User Profile Service on the Application server, now I'm getting these non-stop messages in the log:
    SharePoint Web Services Round Robin Service Load Balancer Event: EndpointFailure Process Name: w3wp Process ID: 6088 AppDomain Name: /LM/W3SVC/261708640/ROOT-1-130709594108226406 AppDomain ID: 2 Service Application Uri: urn:schemas-microsoft-com:sharepoint:service:9b3095eda69947b299d2f873bbfee5ad#authority=urn:uuid:a01381a61b244525ab4fec30cde9dc5f&authority=https://ApplicationServerName:port/Topology/topology.svc

    http://ApplicationServerName:port/9b3095eda69947b299d2f873bbfee5ad/ProfileService.svc
    This time, the messages are referring to the same server - the Application Server.    In my original question, I should've differentiated the server names when I pasted the message.  Originally the message was referring to the Application
    Server and Affected Endpoint was referring to a WFE.   I'll edit my original post to make it correct.

  • Configuring 2 css11503s for multiple service load-balancing

    here are my questions:
    1) how do I configure an additional vip address? e.g. I'd like to configure a vip - 19.10.28.215 to load-balance http traffic to 10.15.15.25 and 10.15.15.26?
    2) I presently have a static route in my core router "ip route 10.15.15.0 255.255.255.0 19.10.28.210". (this enables the load-balanced servers to connect to Oracle servers on the Core network). do I need to configure a new route on my core router when I add the additional vip 19.10.28.215?
    relevant references and/or examples will be much appreciated.
    dayo

    1/ configure the following :
    service web1
    ip address 10.15.15.25
    active
    service web
    ip address 10.15.15.26
    active
    content WEB
    vip address 19.10.28.215
    proto tcp
    port 80
    add service web1
    add service web2
    active
    2/ I would create a redundant-interface and point your static route to this redundant ip address.
    you should not use vip address in static route.
    VIP address should only be used when you want to reach the vip address not a when you want a direct connection to the real server.

  • Time service load-balancing

    Hi,
    I have a question about load-balancing facilities for Time service. If I
    schedule a TimeScheduleDef object to run at certain intervals, does the
    run-time environment take care of load balancing it across multiple machines
    on a cluster?
    Thanks,

    WebLogic Time is not a clustered service -- it is configured per server and
    load balancing is performed.

  • SMA Web service load balancing issues.

    Hi,  We have configured 3 servers with the SMA web service
    https://machinename1.domain.com:9090
    https://machinename2.domain.com:9090
    https://machinename3.domain.com:9090
    We have load balanced these 3 web services using F5 load balancer and have the LB site set as https://smaws.domain.com
    We used this URL with Windows Azure Pack automation endpoint and that seemed to work.
    We are not sure if this is working properly or not.   
    How can we test?   Should the URL to the web service contain a guid?
    https://yoursmaserver:9090/00000000-0000-0000-0000-000000000000
    We have tried the following but all of them produce errors.

    We do have the webservice configured in IIS with host header smaws.domain.com,  machinename and machinename.domain.local.
    Thanks
    Thanks Lance

    So in this case you need to register the SMA Runbook Workers (do this on machine 1):
    $webService
    = "https://localhost"
    $workers
    = (Get-SmaRunbookWorkerDeployment
    -WebServiceEndpoint
    $webService).ComputerName
    if($workers
    -isnot [system.array]) {$workers
    = @($workers)}
    $workers
    += "MachineName2"
    $workers += "MachineName3"
    New-SmaRunbookWorkerDeployment
    -WebServiceEndpoint
    $webService -ComputerName
    $workers

  • Database Native web services - load balancing,  Instrumentation , security

    Hello –
    I’m proposing use of Database Native web service in our company. Our architects are asking following questions so appreciate your help
    a.     How do you load balance across the DB WS (is there a way to use the F5 to detect downtime and balance the load across the DB servers)? We will be using RAC configuration with 3 nodes.
    b.     Our architect have security concern as user id/password information are in the web service URL, which may prove to be an issue. Is there a way to mitigate this risk?
    c.     Instrumentation in this approach (db native services) is questionable due to development/auto gen of the service logic from the DB itself. We may investigate wrapping the services with OSB to give us an additional instrumentation, policy enforcement, endpoint mediation and security proxy. Thoughts??
    d.     Architect are curious regarding any potential performance issues this may have on the DB server.
    Thanks

    Hi
    We've recently begun using Native Web Services, intending to roll out this approach across the enterprise, but we've encountered 2 significant problems so far, which you may want to consider before proceeding ...
    1. NWS returns an exception if the underlying PL/SQL returns a null value - even if the PL/SQL has completed successfully, and null is a legitimate return value (see SR 3-6201969101 - it contains simple instructions to recreate the problem)
    (I raised it in this forum but there were no replies - SOAP Fault when returning null from a Native Web Service Stored Procedure
    2. The sequence of values returned in the NWS response message is the opposite to the sequence declared in the auto-generated wsdl - i.e. schema validation will fail (see SR 3-6209016991 - it also contains simple instructions to replicate)
    We have coded a workaround for problem 1. where we return <EMPTY> in place of null, and check for it in the client, but without proper resolution we're not prepared to use NWS elsewhere
    As a workaround for problem 2. we removed schema validation, again not ideal
    Both SRs were escalated 9 days ago, but are still outstanding
    Incidentally our database is 11.2.0.1, but I've tested on 11.2.0.3 and both problems are still present
    We also wrap the NWS services using an OSB Proxy Service, and came across the same security issue that you describe (b) - to provide the credentials required for the NWS, simply create a Service Account (containing the credentials) inside OSB and attach it to the Business Service which invokes the NWS (http://docs.oracle.com/cd/E17904_01/doc.1111/e15867/service_accounts.htm)

  • Livecycle Connector to Sharepoint behind load balancer

    In the environment of our customer, there is a load balancer in front of 2 sharepoint servers.
    Then the PDF document is uploaded from the Livecycle server to sharepoint (via the load balancer).
    However, occasionally it will fail to place the PDF to the folder specified, and placed on the outermost folder in sharepoint. 
    May we have any hint to fix the problem?
    Thanks.
    Raymond

    Trevor,
    I'm sorry to say that extending the Default zone to, say, Internet, did not change the behavior... even with the introduction of host header information.  Could it be something to do with my use of ports?  I am very new to SharePoint. Should I
    be extending the applications (I have many on the same server) and use host header information in place of using any explicit port information when creating these extended zones?

  • CSS11501 load-balancing IPv6 services

    Hi,
    I'm new to content networking and load-balancing.
    I am setting up a new nameserver network site and have the following equipment:
    - Cisco 2811
    - Cicso CSS11501
    - Cisco Catalyst 2960
    This site will have 2 nameservers which I want to load-balance behind the CSS11501. The network will be setup like this:
    Internet
    |
    Cisco 2811
    |
    CSS11501
    |
    Cisco 2960
    |
    Nameservers 1 & 2
    The CSS11501 will be in routed mode and will have a publicly addressed VIP (eg, 203.x.x.x) for the DNS service and the name servers will be privately addressed (eg, 10.x.x.10 & 10.x.x.11). I'm hoping this will work fine and serve the requested IPv4 DNS requests.
    I would like the nameservers to also operate on IPv6 and serve out IPv6 DNS requests but am not sure the CSS11501 can perform IPv6 service load-balancing.
    My question is, does the CSS11501 support IPv6, load-balancing IPv6 service requests?
    Thanks in advance.
    Richard.

    Gilles,
    Thanks for the reply.
    On another site I was looking at rolling out a Catalyst 6500 CSM module to do the exact same thing as the site I have the CSS11501's at, but it too does not support IPv6 from all I could find. Does the ACE provide all the functionality of the CSM plus IPv6?
    Thanks.

  • Could not retrieve Enterprise Global Template - Load balancer issue

    Hi,
    We have 4 Project Server 2010 servers. The 4 web servers are load balanced by networking team with sticky session configured.
    When we try to connect to the Project Server using MPP 2007 SP2, it fails saying 'Could not retrieve Enterprise Global template'. It works perfect when we point to a specific server by specifying the IP address for server name in the 'hosts'
    file.
    Earlier we observed some errors in the event viewer related to the SharePoint's internal load balancer for which restarted the 'Project Server Application' on each web server and it got fixed.
    Now, the only entries that we see related to load balancer are as mentioned below as Information (not errors).

    Could the issue be due to network load balancer?
    Could the issue be due to Sticky session configuration on the load balancer.?
    How can we get to the root cause of the issue?
    Which logging category should we set to 'Verbose' that can give us some hint.
    Update: We tried to capture the requests through fiddler and observed that when fiddler is running on the client computer then the connection works perfectly fine even through the load balancer. Probably fiddler is reformatting the SOAP
    envelop of the web service requests the way it should before sending the request to the server.
    If we do not run fiddler and run some other similar tool (like Charles) then it again gives the issue and the request stucks at /PWA/_vti_bin/psi/winproj.asmx
    We ran Wireshark on the servers and found the following for that web service call:
    [TCP Previous segment not captured] Continuation or non-HTTP traffic.
    Please let me know if someone could provide any hint what can be done next.

    There are several ways to configure your load balancer.   I would suggest that you work with the network engineer, the load balancer vendor and your project administrator to resolve this issue. 
    Basically you need URL to be resolved correctly.  Also, I don't believe PS2007 did a good job handling load balancing, so you may need to bring someone in good with IIS and see they can tweek IIS to manage the cache better.
    As I go back and look at your analysis, I think you should probably look at upgrading to Project Server 2013.  They made some improvement in load balancing and the management of distributive cache.
    I assume you have 4 WFE because you have thousands of project users.  Roughly how many  you have?  Over 1000, over 5000
    Have you tried to see if using two load balancing work?  How about just one front end.  I often see companies scaling SharePoint and Project server to extremes.

    Regards, Harvey

    Hi Harvey Flaisher,
    Based on the error message, this seems to be a service application not working issue.
    Please check the ULS log or Event log to check in which service application the error occurs, like BCS, secure store service, app management service, then re-provision the service application using PowerShell command, or re-create the service application
    from UI to check the result.

  • Load balancing and clustering for SQL SERVER ANALYSIS SERVER instances to access large number of concurrent users for bi site

    HI
    how to do analysis server clustering 
    we have sharepoint bi site and we published many dashboards pointers ,filters kpis

    so for maintain this requirement how we apply clustering for ssas intances 
    and also it has load balancing 
    adil

    Hi Adil,
    According to your description, you want to implement SQL Server Analysis Services Clusster and Analysis Services Load Balancing, right?
    In SSAS, we can design highly available solutions in Analysis Services by using: network load balancing (NLB) technologies, failover clustering technologies, or both. For the details about implemention, please refer to the links below.

  • OSB Load balancing issue

    We have a situation in our project.
    We have weblogic8 sp5 server having a MDB deployed which consumes messages from distributed queues created on WLS8. OSB business services post messages on these distributed destinations.
    Set up:
    Non production environements have 2 instances of wls8 servers and 2 instances of OSB(weblogic) servers.
    Production environments have 4 instances of wls8 managed servers and 2 instances of OSB(weblogic) servers.
    Weblogic 8 server has a custer created with only hostname comma seperated. e.g. host1,host2.
    OSB(weblogic) server has cluster created with hostname and port comma seperated. e.g. host1:port,host2:port.
    Scenario 1.
    When wls8 cluster address is used in OSB business services, load balancing is not happening. Messages go on only one of the wls8 managed server. If this server goes down,then only messages goes on the other server. With this, we have got fail over and not load balancing.
    Scenario 2.
    When wls 8 managed server urls are used with comma seperated in OSB business service, some times load balancing happens. This is also not conclusive as when any of the wls8 managed server goes down and comes up, load balancing stops working and all the messages goes to one of the up servers.
    Scenario 3.
    On produciton environmet, we have 4 instances of wls8 managed servers and 2 instances of OSB(weblogic) managed servers.
    As discussed in scenario1, when cluster address is used, load balancing does not happen and all the messages go to 1 of the 4 managed servers. When comma seperated urls are used, some times load balancing happenes but it is load balanced in 2 of the wls8 managed servers. Other 2 do not get any messages.
    We have custom error handling done to catch all the errors occured when any exceptions occurs in proxy service or while invoking business service. Tried adding 4 different urls in end point uri of busness services. If any of the endpoint is down, it gives an error and message flow gets aborted. Tried with enabling retry count. With this, when any endpoint down, it raises an error which is collected in custom error collector and then tries with another available uri. With this, for any error and after successful message flow, an error is logged.
    Any pointers on above points will be helpful to solve our loadbalncing issue.

  • OSB Load Balancing

    Is there any way to load balance a proxy service in OSB?
    For my project, I have an http/wsdl based proxy service that is transforming a pretty large message and routing it to a business service based on a jca adapter. If I monitor my cluster(2 nodes and an admin server) during a load test through soap ui, I only see one of the nodes doing work. The other looks untouched. The url I am hitting is the load balancing url setup on the http tab of the cluster in the weblogic console.
    In this doc it says that proxy services are pinned to a single managed server for polling service, but nothing about http:

    Is it possible to have the proxy service load balanced across multiple nodes, or is there some other method of doing this?
    Thanks for any help.

    Please refer OSB Deployment Guide -
    3.3.1 Load Balancing HTTP Functions in a Cluster
    Web services (SOAP or XML over HTTP) can use HTTP load balancing. External load balancing can be accomplished through the WebLogic HttpClusterServlet, a WebServer plug-in, or a hardware router. For an overview of a cluster topology that includes load balancing, see Figure 5-1. Oracle WebLogic Server supports load balancing for HTTP session states and clustered objects. For more information, see "Communications in a Cluster" in Oracle Fusion Middleware Using Clusters for Oracle WebLogic Server.
