Validation required on software load balancing

We have created software load balancing between two web servers with 80/20 load shared in SP 2013 farm configuration. How could we validate this is working as disired while user access the site. Is there any there any monitoring tool auilable to monitor
this.

Hi TanGrren,
Software loadbalancing, you mean NLB which come by dafault on windiows server?
if ther is any other third party software then they would have the option to show the load. (if possible please name the software which is being used)
If not i would rely on Perfmon (performance monitoring)and place some pointers on the URl and get the stats.

  • Software load balancer

    Hi,
    os platform= oracle linux
    database = 11g 11.1.0.7
    apps = 12.1.2
    regarding choosing load balancer which load balancer is good for Ebusiness suite instance
    Hardware level or software level
    kibndly advice

    If we want to go with hardware level do we have to do something with Apache loadbalancer or skip that step?Which configuration you are planning to go with? You still need to do configuration changes at the application tier nodes.
    If we choose Hardware level load balancer its configuration has few steps compare to software level ?Going with hardware load balancer still requires many changes and configurations at the application tier nodes as well as the hardware load balancer and I would say the steps are not less comparing to software load balancer.
    what is the major difference between hardware level and software levelI believe this is not answered in any of the docs/links referenced above, so please log a SR to get the correct/proper answer.
    Thanks,

  • Software load balancing in weblogic

    Hi All,
    we need to configure a Software load balancer for one of our evnironment as we will not be getting hardware load balancer for the same.
    we have weblogic and soa (11.1.1.5) installed on one machine and we will create two managed server which will be in a cluster.
    Please provide any pointer or input for configuring software load balancer for our requirement.

  • How to configure software load balancer for R12.1.3

    Dear All,
    I need to configure software load-balancer on application tiers and i need to know if its possible to have a software load-balancer in place of hardware load balancer if i need to route the load on two application nodes.
    Thanks !

    As we do not certify, nor support 3rd party loadbalancers we can not confirm that the Piranha loadbalancer will perform as expected with EBS. The basic minimum requirements or loadbalaning is that it has death detection, and session / cookie persistence We also typically require that a hardware loadbalancer is used. Internally we use F5 loadbalancers, and Cisco ACE.
    What are the limitations of a software load balancer compared to hardware ? As mentioned above, your software balancer should has the capability of "death detection, and session/cookie persistence" -- More details can be found in (Implementing Load Balancing On Oracle E-Business Suite - Documentation For Specific Load Balancer Hardware [ID 727171.1]).
    Oracle Web Cache can be used as a software load balancer (which is an Oracle product), but Oracle recommends you do not use it in production instances.

  • Weblogic cluster software load balancer

    Hi,
    We are currently using Weblogic domain as a Proxy Plug-In for High Availability test as it’s explained in this blog http://andrejusb.blogspot.com/2009/04/weblogic-load-balancing-for-oracle-adf.html.
    Its working fine for POC project but what software load balancer would you recommended for production environment on Linux? (Assume that we don’t have a hardware load balancer).
    - Oracle active-passive OHS web-tier clustering.
    -Using Linux open source Linux Software(e.g. HAProxy and KeepAlived as explained here http://biemond.blogspot.com/2010/04/high-availability-load-balancer- for.html
    -Using any other software load Balancer
    I would appreciate if anybody can provide some recommendations/links etc.
    Thanks
    Alex

    Hi Alex,
    Yes you should never use HttpClusterServlet, not even for fun ;-)
    We use mod_wl (Web Server Plug-In) for Apache for several customers and that works fine.
    Check this:

  • HTTP logs not created when using software load balancer

    This is my setup:
    1. I have a server running a software load balancer - call it A
    2. There are two servers clustered under A - call it X and Y
    3. I am able to access the application deployed on X and Y through A.
    Fail-over also works. Shutting down X when the application is up and running routes the requests to Y and vice-versa. All is well until this point.
    Problem is:
    Let us take server X.
    $ORACLE_HOME/Apache/Apache/logs does not have an access log in it. (It
    however has an error log.)
    Access logs are not created when accessing the servers in the cluster (X and Y) through the load balancer URL.
    However, when accessing the individual servers in the cluster (with their URLs), access logs are created.
    Specifics on the setup:
    1. A, X, Y - all three are OAS 10.1.3.2
    2. All three are deployed on individual server machines
    3. All three servers have one OC4J instance each running in them
    4. The software load balancer used is from WebLogic 8.1sp5 - basically to create a *.war file that has the details of X and Y (servers in the cluster)
    5. This *.war file is deployed on A
    6. Server A, the one that has the software load balancer, DOES NOT have AS control. One of the other servers in the cluster does.
    Has anybody encountered this problem before? Or is there anything wrong
    with the setup? What is the resolution for the same?
    Any help is greatly appreciated.
    Thank you.

    Thank you, Jacco. You are right in saying that the software load balancer does not route the request to Apache and hence the logs are not created.
    While the logs are not critical to the component we are working on, was just wondering why they were not being created.
    As regards your comment on FastCGI, there is a FastCGI directory created under $ORACLE_HOME/Apache/Apache/logs - but there is nothing in it. Neither do the error logs have any information pertaining to FastCGI.
    Anyway, I am not going to worry about this issue anymore - may be sometime in the future will try to use a different software load balancer and see if it makes any difference.

  • Hardware or Software Load Balancer

    Hi all,
    We're looking to have two OHS servers at the top layer which we then want to load balance using a DNS Alias. Does anyone have any recommendations or useful reading materials on choosing between software and hardware load balancers? I've seen and maintained Hyperion implementations that successfully using both, but would like to understand the pros/cons of each approach.
    Also, does anyone know of any recommendations from Oracle on which approach with Hyperion / configuration recommendations when using Load balancers? The EPM High Availability guide 11.1.2.1 doesn't say much about load balancers sitting above the OHS layer
    Thanks
    Nick

    Hi Nick,
    The big problem with round-robin DNS is if one of your OHS nodes goes down every other user will head a bad URL. A hardware load balancer when setup properly will have much more intelligence and can sense if a site is down and automatically send all requests to the online node. Higher end hardware load balancers usually offer features like SSL Offloading and content compression.
    This being said there are real costs for hardware load balancer which can run into the 10's of thousands of dollars if not hundreds of thousands of dollars.
    You may also want to review the content available at: http://www.loadbalancing.org/
    If you are looking for something in between round-robin DNS and a true hardware load balancer take a look at Linux LVS at: http://www.linuxvirtualserver.org/ -- this does require a bit of linux knowledge.

  • OAM Webgate Ip validation problem caused by load balancer...

    Hi all,
    In my topology, i have 5 webgates on 5 OHS web servers running in reverse proxy mode . Those web servers are behind load balancer. Since load balancer is working in proxy mode, all requests seems to be coming from load balancer vip and this prevents ip validation at webgate side . Does anybody think that it is possible to solve this issue without changing load balancer configuration..
    Regards,

    Hi,
    Randat, how can i reconfigure ip validation against x-forwarded-for? A custom authz plugin, or only a configuration change ? I'll keep on searching on this solution, but if you can share your solution , it'll be appriciated..
    Ambarishmitra, i want to use ip validation but since all requests are coming from single ip i can't distinguish client ip's, that's my problem..
    Thank you both,

    Lets consider forms server component of middle tier
    Can there be multiple INSTANCES of forms server within SINGLE INSTALLATION ???
    If it has to be MULTIPLE INSTALLATIONS, then it will require multiple physical machines
    What is software load balancing then ???
    Also read that
    Oracle 9i AS instance is combition of Oracle HTTP Server (OHS) and one or more instances of Oracle9iAS Container for J2EE (OC4J)
    Thus software load balancing can be implemented for Web server component of middle tier using multiple instances of OC4J ???
    Forms metrix server configuration is hardware load balancing ??
    What about Oracle9iAS Web Cache clustering ??
    Please clarify the doubts and suggest me the way
    Thanks a lot

  • Problem Load Balancing connections for Grid Control Console on port 80!

    I have two OMS and I'm balancing connections for Grid Control Console using a Software Load Balancer according with "Oracle Enterprise Manager Advanced Configuration". I have success where the load balancer is listening on port different to 80. When I configure Load Balancer to listen on port 80(architecture requirement) and distribute load between the two OMS(Port 7779), when login to Enterprise Manager Console the URL on the web browser changes to the port configured for HTTP server (port 7780) wich produces an "unable to connect" error message; and this behaviour also happends in some of the internal links of Grid Control Console too. Any ideas?
    Thanks in advance!

  • Network Load Balancing and failover for AFP Sharing

    Dear all,
    Somebody kindly teach me to use round robin DNS to perform the network load balancing, it's success but not the failover.
    I have 4 xserve and want to do the load balancing and failover at the same time.
    I have read the IP failover document and setup it successfully, but anyone know is it possible to do the IP failover for more than 2 server?
    For example, 4 server serving the AFP service at the same time, maybe I have 1 more extra server to do the IP failover for thoese 4 servers.
    As I know, IP failover require Firewire as the heartbeat detection. But one xserve only have 2 firewire ports. May I setting up the IP failover only by a ethernet port and an IP address? does it possible to detect and failover to any server after server down has been detected?
    I believe load balancer maybe the best solution but its cost is too high.
    Thanks any advance!

    well, u have 2 options here
    software load balancing
    request comes it foo.com -> ws7u2 hosting foo.com is configured to run as reverse proxy . this server sends any incoming requests to one of the four back end web server 7 handling your incoming request
    hardware load balancing (this you need to invest)
    request comes to hardware load balancer who responds for foo.com -> sends requests to four ws7 server hosting your application
    you could try out how software load balancing works out for you before you invest in hardware load balancing
    here is more instruction on configuring ws7 + reverse proxy (software load configuration)
    - install ws7 on foo.com
    - create a new configuration (choose port 80, disable java

  • Load balancing v/s Clustering with  BOXI enterprise premium

    We are planning to install Businessobjects enterprise premium on windows2008 server (64 bit) and we are going to use oracle database. my question is
    "Can we set up Crystal reports and businessobjects (web intelligence) both either on clustered environment or load balancer ? "
    If not, can you please let me know what is the best option ?

    Oh. All BOE (this includes Crystal) servers support clustering (and software load balancing via corba).  Only the input and output FRS do not support load balancing. i.e. while you can have mulitple input/output FRS, only one of each is active at a time. The others are passive and will only be used if the active FRS is unavailable.
    As an aside, if I remember correctly, a BOE Premium license is required for clustering.
    So, in essence, you do not need a hardware load balancer to support load balancing for both Crystal and Webi.

  • Virtual BizTalk Server load balancing

    We in process migrating Physical Biztalk server from current datacenter to a cloud based datacenter.
    The requirement is the all server deployed that must be ritualized.We are using Citrix load balancer in the new datacenter and VMware 5.1 as host OS.
    we were not successful deploying the load balancing with NLB and Software LB within the virtual world.
    Please Help

    Seeing that you have an external load balancer available, you really should not be trying software load balancing. Windows NLBS is a software based load balancing and is not really dependent on the physical/virtual hosting of the OS. There are certain gotchas
    w.r.t the NLB modes since they depend on network protocols such as arp, propagation of MAC addresses and usage of the MAC in the L2 routing tables of network devices.
    You should be taking the help of the cloud service provider as ONLY they would have an understanding of their underlying networking infrastructure such as VLANS. addressing, routing rules and such.
    You could also refer to the VMware support forum for KB's such as
    http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1006580
    Most importantly, NLBS is a base OS related service and you're more likely to get a response in the Windows Server Forum. In the specific case of BizTalk, the Windows NLB is only used for hosting the out of process services such as those associated with
    HTTP/s Receive, orchestration published as schemas, web services (asmx) and/or WCF endpoints.

  • Virtual Hosts for Load Balancing

    Hi all,
    So I have two identical servers, that have SOA Suite installed pointing to the same database. (RHEL 4) I have configured the mod_oc4j.conf file for round robin, and then I created a virtual host on the httpd.conf file to point to the load balance hardware.
    It worked! But with a slight issue. The Load Balance server is orasoaqa.tmpw.net:7777, which opens the main Application Server page. However, when I click on BPEL console, or ESB, it continues using the orasoaqa.tmpw.net:7777 virtual, which of course, breaks even trying to login.
    What am I missing here? Here's the entry I added to mod_oc4j.conf:
    Oc4jSelectMethod roundrobin:local
    Here's the entry I added to the httpd.conf on server 1:
    Port 7777
    Listen 7777
    NameVirtualHost XXX.XXX.XXX.XXX:7777
    <VirtualHost orasoaqaapp101.ma.tmpw.net:7777>
    ServerName orasoaqa.tmpw.net
    ServerAlias orasoaqaapp101.ma.tmpw.net
    Port 7777
    </VirtualHost>
    and on server 2:
    Port 7777
    Listen 7777
    NameVirtualHost XXX.XXX.XXX.XXX:7777
    <VirtualHost orasoaqaapp102.ma.tmpw.net:7777>
    ServerName orasoaqa.tmpw.net
    ServerAlias orasoaqaapp102.ma.tmpw.net
    Port 7777
    </VirtualHost>
    Yes, the port for Application Server and the port on the Load Balancer are exactly the same, I hope this isn't the issue.
    Any help would be greatly appreciated.
    Thanks!

    Pooja,
    I am unable to find the directory 'j2ee' in 9iAS
    ORACLE_HOMEThat's because ORACLE_HOME for 9iAS is different to ORACLE_HOME for the Oracle database (server).
    On our SUN [sparc] Solaris 9 machine:
    [9iAS] ORACLE_HOME = /u/app/oracle/product/ias
    [9i Database] ORACLE_HOME = /u/app/oracle/product/9.2.0
    And the "j2ee" subdirectory is under "/u/app/oracle/product/ias"
