I have more then half decent results with webcache as load balancer, but it still is a round robin (as mentioned before). This means that a session will not be transfered from one application server to the other once the session has been created.
So far I did not discover any benefits of a hardware loadbalancer over webcache, because (here it is again:) you are not able to transfer open sessions from one application server to the next. This has to do with the Oracle Forms architecture. In fact it is still client-server, only with the application server functioning as extra server ;)

  • FRM-92101: Load Balancing Forms 10g with Webcache

    Hi,
    I´m having some problems with Oracle Forms and Webcache 10g and I was wondering if you
    could help.
    Machines: (Pentium IV 2.6 GHz; 2GB RAM; 80GB HD)
    A. Red Hat Linux AS 2.1
    Oracle AS 10g - Infrastructure Installation
    B. Windows 2000 Server - Service Pack 4
    Oracle AS 10g - BI and Forms Installation (Using Infrastructure on machine A)
    C. Windows 2000 Server - Service Pack 4
    Oracle AS 10g - BI and Forms Installation (Using Infrastructure on machine A)
    I didn´t apply any Patchsets of Oracle AS 10g. My current version is 9.0.4.0 .
    Goal:
    Use Oracle Webcache 10g on machine B for Load Balancing an Oracle Forms Application
    on machines B and C.
    Facts:
    The Oracle AS 10g installation on the 3 machines was made without problems.
    The Forms Applications are running without problems on both Forms servers in machine B and C.
    Symptoms:
    I´m getting the following error when I try to access the forms application through Webcache:
    FRM-92101: There was a failure in the forms server during startup.
    This could happen due to invalid configuration.
    Please look in the web-server log file for details.
    But, this error happens ONLY when BOTH OC4J_BI_Forms instances (machines B and C) are
    running.
    When just one of the OC4J_BI_Forms is running everything works fine.
    Webcache Configuration:
    I´ve followed Metalink note 207668.1: Configuring Web Cache as a Load Balancer for Application Servers
    step by step to make the configuration of the following components:
    1. Configuration of the origin servers
    2. Configuration of Site definitions
    3. Configuration of Site to server mapping
    After that, I´ve follwed the Metalink note 229900.1: Integrating and using Web Cache with Forms 9i for Load Balancing
    step by step to make the configuration of the following components:
    4. Session Binding
    Then I try to test the Load Balancing and I got the error FRM-92101 when both OC4J_BI_Forms
    instance were running.
    I´ve searched Metalink and found note 268830.1: Webcache Won't Load Balance 2 Forms Instances.
    Following the note instructions I did the following changes:
    Added these lines at the end of HTTPD.conf (machine B):
    CookieTracking On
    CookieName myformscookie1
    Added these lines at the end of HTTPD.conf (machine C):
    CookieTracking On
    CookieName myformscookie2
    In Webcache configuration:
    I´ve Changed the default session binding from JSESSIONID to "ANY SET COOKIE" for the
    site's session binding.
    But even after these changes I´m getting FRM-92101 error on the same conditions.
    How can I solve this problem ?
    Thank you in advance.

  • Load Balancing Forms Services with an effective healthcheck

    I am in the process of configuring two forms 11.1.2 servers running with weblogic 10.3.5 with multiple forms applications clustered across both physical servers. We are looking to load balance to the various forms applications using a hardware load balancer. Can anyone comment on their experience with setting up effective application healthchecks using either hardware or software load balancers?
    For example say that we have 3 applications clustered across 2 servers with the following
    URLs:
    http://server01:7777/forms/frmservlet?config=myapp1
    http://server01:7777/forms/frmservlet?config=myapp2
    http://server01:7777/forms/frmservlet?config=myapp3
    http://server02:7777/forms/frmservlet?config=myapp1
    http://server02:7777/forms/frmservlet?config=myapp2
    http://server02:7777/forms/frmservlet?config=myapp3
    We would need a checking mechanism on the load balancer that could tell if myapp2 was down on say server01 and therefore block traffic to that application yet keep traffic open for the other 2 apps on the same server.
    A specific difficulty with forms is that when the database behind the application is down forms services will return an error message within a displayed error form. From the load balancer's point of view the forms services are "up". We need to find a way of detecting that the application is actually available and not just that the forms services themselves are available. To detect that the forms services are available we might normally use the status check:
    http://server01:7777/forms/frmservlet?ifcmd=status
    however this will only tell use the availability of the forms services on a physical server and not whether any actual applications are available.
    I am aware that f5 do a BIGIP offering that includes some Oracle Forms specific components. Can anyone comment on how they have setup Oracle Forms healthchecks using various load balancing methods. In particular if a load balancer is limited to using WGET commands to check HTTP returned content is there a way of checking a forms application's availability and if not how have other people achieved an effective healthcheck?
    Many thanks,
    Philippe

  • Load Balancing - Forms Metrics Server

    Hi everyone, i have a doubt, for implemeting Load Balancing with Forms Metrics Server previous i must have configured Shared APPL TOP?
    And for Load Balancing JServ also i must have configured Shared APPL TOP in all my applications servers?
    Thank you very much for helping

    It is not a must, but it is recommended. If you are planning to configure PCP then it is a must.

  • Forms 6i and Reports 10g

    Hello together,
    You can see at the subject that I want to combine Forms 6i and Reports 10g.
    Why? 6i does not support html interpretation and unicode.
    So what do you think about the kombination with old (Forms) 6i and new 10g (Reports)?
    How does the Reports published in 10g ?
    Paul
    ps: sorry for my bad english

    Reports in WebForms needs OAS (Oracle Application Server) to be published, they are viewed over the net in a browser.
    It's a very bad idea to combine them and most of the things will not work, even if make them work it will cost you lot more than just simply, migrate your application to Froms 10g.
    It would be easier for you to migrate your whole application to Forms 10g

  • Question about load balancing between Portal and ABAP

    Hi,
    I have the problem whit load balancing between Portal and ECC (ERC) ABAP
    Exist two system:
    1) ECC (ERP) ABAP = Backend     Module = HR
    2) EP (JAVA) = Frontend
    The users (9000 users) logon in the EP and run query (data personal) in the ECC.  The problem to all user connect in Central Instance and not in the Dialog Instance.
    How can balancing the conecction HTTP (EP) to ECC (ABAP)??
    I need balancing in the ECC to Dialog Instance

    Jco -> right. Another possibility is that you use iviews that point to the backend in this case you will need to use a load balanced entry for the backend system in the [system landscape|http://help.sap.com/saphelp_nw70ehp1/helpdata/en/47/8c1e438d7017fce10000000a42189c/frameset.htm] -> SAP_R3_LoadBalancing
    If you have ESS deployed on your portal, you will most probably need to do both.

  • Running forms 6i and reports 6i from oracle portal

    hi all,
    is it possible to run the forms and the reports developed in
    forms 6i and reports 6i from oracle portal
    or
    is it possible to export forms 6i and reports 6i into oracle
    portal
    prabhakaran

    Dear Friend,
    It is possible to deploy 6i forms & reports by Apache Web
    Listener. You will have to edit the httpd.conf configuration
    file and add your virtual path as Alias. The Virtual Paths are
    /dev60html/
    /dev60cgi/
    /jinitiator/
    /dev60temp/

    Thanx.

  • Recommended configuration for load balanced Portal with load balancer, multiple gateways and multiple servers.

    Does anyone have a recommended network, hardware and software configuration guide for a Portal installation running with multiple gateways load balanced (ie one URL) that talk to multiple servers?

    David,
    We've used Resonate (software) to load balance the gateways. It allows
    you to group all the gateways under 1 virtual URL and load balance the
    incoming connections over each gateway depending on the rules that you
    define in Resonate. Look in the SUN portal whitepapers there is one that
    talks about it specifically.
    As far as load balancing the calls to the portals, the gateways will
    automatically load balance across all the portals that they know about
    using a simple round-robin rotation. You may be able to use Resonate in
    front of the portals but you may need to activate persistance within
    Resonate to ensure that the user always ends up on the portal that he
    established his initial connection on (if you want that), check with Sun
    on this one.

    Just ran into this problem last Tuesday, Nov.30 and applied the changes today.
    My configuration is similar to yours: 9.0.4 web cache on machine A, 9.0.4 10gAS forms and reports standalone on machine B and C (not a cluster, no infra).
    I appended the Cookie lines you mentioned in httpd.conf located in $ORACLE_HOME/Apache/Apache/conf in both machines B and C.
    One important thing you may have missed. After changing httpd.conf in each 9iAS instance, you need to make the change known to dcmctl so issue:
    dcmctl updateConfig -ct ohs
    Then do the following for each 9iAS instance and it should be ready for webcache:
    dcmctl stop
    dcmctl start
    Setup Any-set-Cookie in webcache instead of JSESSIONID and the whole thing should now work. You can run a form through machine A which will load balance to either machine B or C (which can both be up). Then, try shutting down 9iAS on machine B or C and run a form again. They now all work.

  • Load Balancing Forms and Reports with Web Cache

    We are planning to add a second OracleAS 10g middle-tier application server to an existing 10g middle-tier.
    Both middle tiers will provide Forms and Reports.
    Users must pass through two static HTML pages before starting Forms.
    We plan to use Web Cache to load-balance (probably using round-robin) between the two middle-tiers.
    Does anyone see any problems with this solution?
    All comments/suggestions welcome.
    Thanks,
    Jim

    You could also load balance the two OC4J's using standard servlet mechanisms. I know that there exists a couple of good notes on Metalink. Go and do a search.

  • Load Balance Forms and Reports Services

    Is it possible to Load Balance an application (written in Developer 9i) between
    two computers running Oracle Application Server 10g (9.0.4) Forms and Reports Services ?
    If it is possible, can anybody give an example or some kind of documentation, because
    the product documentation is not clear.
    Thanks in advance...

    Yes it is possible, but it all depends on what is your definition of load balancing?? Do you mean hardware machine balancing or service availability??? this is a large territory and you have to be specific, you even have the RAC.
    Oracle has [Oracle Application Server High Availability |http://download.oracle.com/docs/cd/B14099_19/core.1012/b14003/toc.htm] and metalink Note:740202.1 explains in detail how to configure it.

  • Using Web Cache to Load balance Forms Server application.

    Hello,
    I apologize for cross posting this question in the Forms and Caching Services forum. But I thought my question will have a better chance.
    I have read that it's possible to use Oracle Web Cache as a software load balancer between multiple Application Servers.
    We are running Oracle9iAS R1.0.2.2.2a, with Forms/Reports6i servers on 2 Win2k boxes i.e our Forms6i application is deployed on two seperate boxes in two distinct locations. Users at each location, use their respective App Server url.
    Since the application is the same i.e. Forms6i code/fmx is the same for both locations, I am looking into loadbalancing and failover capability that Web Cache might be able to provide.
    I AM ONLY LOOKING AT THE LOADBALANCING & FAILOVER capabilities and NOT caching.
    So basically all users from both locations will point their browser to this Web Cache and the Web Cache will direct each connection to either of the two boxes. So, if either of the boxes dies, Web Cache will divert the requests to the other box.
    My concern is whether Web Cache supports this for the Forms requests that it will receive from the users. We are using Servlet Deployment of Forms, so technically, all communication is going though the HTTPD.
    Has anyone done this or has any ideas as to whether it's going to work or not? Oracle's FAQ insists that Forms is not supported. But I want to make sure that even loadbalancing is not supported. And if not supported then is there any other solution.
    Any comments appreciated.
    Thanks,
    Manish

    Using Web Cache to load balance servlet-based Forms (6i and 9i) is unofficially supported. I say "unofficially" because we have actual customers doing it and getting support, but the 2 development teams (Forms and Web Cache) haven't actually done any integration testing of this sort of configuration yet. For your case, please contact your Support rep and ask what was done to use Web Cache as a load balancer for Forms6i at METRO in Germany. The Forms product managemment team is writing up a white paper to describe how to do it, but until then, you'll need to go through Support. Please contact me if you want more information.

  • How to migrate my oracle forms 9i and reports application..

    Hi,
    we have this budgeting application developed in oracle forms 9i,reports integrated in oracle portal. Now we have to move this application from oracle 9i to oracle 10g and have to integrate it with new portal again.
    Can anybody pls help me how do I migrate this application to oracle 10g AS and integrate it with portal so exact replica which was on oracle 9i portal is there on my new oracle 10g integrated within the portal.

    Are you currently deployed on the web or as c/s. Generally speaking for upgrading Forms its a case of open in the builder, regenerate and run. For c/s to web there may be some extra steps to do but generally speaking most Forms will run out of the box.

    There is also a batch option to help you and there are of course Oracle partners who can help as well.
