Forms load Balancing

Is it possible to use Oracle Web Cache 10.1.2.2 in order to load Balance stand alone Oracle forms / reports servers ver. 9.0.4 ?
What other options is possible for load balancing of orcale forms servers 9.0.4 ?
Thank's

  • Forms/Reports 11.1.2 Load balancing on Linux

    Hi, I put this on the Reports forum but didn't get a reply, it has a Forms element to it, so I thought I would post it here as well.
    I have three different applications which will run on a single Clustered Weblogic Environment with two Nodes.
    So we will have 10.3.5 Weblogic Server, and Forms and Reports 11.1.2.
    With respect to the Reports, we have three separate applications so it seem logical to separate out the reporting to three separate report servers, but as we have two nodes in a cluster I guess that we will need three servers on each node.
    Is there any documentation on this approach and also on load balancing between the servers?
    Two systems invoke the report servers from Forms using the run_report_object, the other runs from the linux command line (ie rwrun). How does the load balancing work in this situation with the calls from the Forms?
    I have searched through the Oracle Reports documentation and I couldn't find much that clearly addresses these issues.
    Any help gratefully received.

    Any thoughts?

  • 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

    Did you ever Get this to work?
    I am having some problems trying to load balance with Oracle Forms, Discover and reports Oracle Application Server Release 10g (9.0.4.0.2) and I was wondering if you could help. Has any one ever got this to work consistently? We are an ERP product written mostly in forms (904) and are trying to implement are largest customer there performance issue so we need the load balancing to work. Will also accept other recommendation as cost effective as solutions.

  • Load balancing 10g forms - Connection from new browser window not supported

    Load balancing 10g forms - Connection from new browser window not supported
    We're experimenting with using webcache to load balance between multiple applications servers running OC4J forms processes.
    We currently have one machine with infrastructure and mid-tier (BI & Forms) installed, which is being used for the webcache functionality, this is load balancing between 2 other servers each of which just have the mid-tier (BI & Forms) installation
    In order to get this to work, I had to follow the instructions in the Forms deployment guide : http://download-uk.oracle.com/docs/cd/B14099_11/web.1012/b14032/tuning.htm#sthref707
    The main gist of this is that you need to set the following in the orion-web.xml file in order that the sessions are maintained:
    <session-tracking
    cookies="enabled">
    </session-tracking>
    This all works fine in most cases.
    The problem I am having is if I do one of the following on the client machine:
    1) From IE6 / IE7 run a copy of a forms application. Then open a new window using the "New Window" menu option, and attempt to run another forms application.
    2) In IE7 or Firefox 2.0 open a copy of the forms application, and then open a new tab and try and open another forms application.
    If I try either of these I get a FRM-92101 error, and the following is displayed in the java console:
    oracle.forms.net.ConnectionException: Connection from new browser window not supported
    From trawling various forums (including metalink and otn) it looks like a problem with the way coockies are handled.
    Unfortunately the usual workaround is to ensure that the session tracking option in the orion-web.xml file is disabled.
    The problem is that I need this enabled in order for the load balancing to work.
    Does anyone know of any other workarounds or patches that might help resolve this?
    We're using Application server 10.1.2.0.2 running on windows 2003 servers.

    You were right. Carriage returns were stopping it from working (the document is laid out over separate lines, so I assumed it would make no difference...).
    I've now managed to get it so the forms at least run, but they are all being run in the forms OC4J instance on the same machine as the OHS.
    Has anyone actually managed to get this to work, or am I doing something wrong?
    I did wonder if using an OHS instance on a machine with no forms installation would make any difference?
    I had raised a support call via metalink on this subject, but they eventually came to the conclusion that the only way to do this is with a hardware load balancer (Despite several documents suggesting that webcache is the way to go (including the forms deployment manual)).
    I'm at the point now of giving up and writing some custom scripts to do the job instead...

  • FRM-92101: Load Balancing Forms 10g with Web Cache

    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 acces 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.
    Marcus Santos.

    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 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.

  • Load Balancing with forms server 10g

    Hello,
    i've a cliente which is right now processing a migration from a client-server 6i platform (using Terminal Servers) to a forms 10g web platform with several Application Servers 10g in standalone.
    At the end, client want to enable Load Balancing in order to have some manage at each Application Server load.
    The idea to accomplish is to have an hardware Load Balancer. The client already has a CISCO CSS 11503 SSL.
    Is there any documentation where i can check more info about the compatibility/configuration to this architecture.
    Thanks for your attention.
    regards,
    Pedro Ribeiro

    You can check this doc Link:[http://download.oracle.com/docs/cd/B14099_19/hpux.1012/install.1012/install/toc.htm]
    It say all about it, and don't mention nothing about a Load Balancer, but I'll try tokeep searching.

  • Load balancing Oracle Forms in Application Server

    Hi,
    We're currently planning moving from client-server forms to webforms running on Oracle Application Server (10.1.2.0.2). To meet our high availability requirements, we plan to run our forms app servers active-active. We're coming a little unstuck determining the best method of load balancing requests between these however.
    Currently the main sticking point is determining whether to go for software or hardware load balancers. One of the main things we're unsure of is how much traffic we can expect to flow through the network. In our client-server environment we typically have 900-1000 active connections during peak load and ~350 forms coming in at just over 300Mb in total.
    If you have any experience load balancing between Oracle Forms on Application Server, we'd appreciate it if you could share details of you setup and how it's performing; particularly:
    * Whether you have software/hardware load balancing
    * The number of connections this supports
    * Details of the volume of network traffic you have
    Thanks,
    Chris

    We have implemented both hardware load-balancers and Webcache as load-balancer. Depending on the situation either may be the best solution. In general we recommend to use hardware load-balancers for production systems that require high availability. However, Webcache is very reliable as well and a Webcache instance can be recovered very quickly in case of a failure (use the cloning facility to create a copy of the instance on new hardware within minutes).
    When using https for your applications we do not recommend to use WebCache as there are several issues to cope with then, one is performance (https acceleration facilities are often part of hardware load-balancers).

  • 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.

  • Deploy Forms and Reports with Load Balancing

    I am trying to determine what we need to install here. I have read OracleAS, Web Cache, Application Server, and
    Forms documents and have no answer still.
    We are currently run 9iAS with Forms and Reports 6i only.
    I did not do any of those installs. We are migrating to
    Forms and Reports 10g. I need to setup an OracleAS 10g
    Forms and Reports application server with the ability to
    do Load Balancing over 2 windows Web servers to handle
    4,000+ users. The application database will be on its own
    Windows server.
    Do I need to install the Infastructure, BI, and Web cache?
    Or just Oracle 10g Application Server option? Or other?
    Do I need to install it on both web servers and do
    something like clustering? Do I need to install Web
    cache? I just took the 10g AS class and basically did not learn anything about deploying Forms and Reports.
    Can anyone give me a place to find the things I need to
    install and setup?
    Thanks.
    Kim

    I am a DBA and have not done an iAS or AS installation
    before but am now required to learn it. We will be using
    SSL and no load balancing hardware. We setup for other
    customer sites and setting Windows servers in the past.
    We have not done load balancing before.
    I am just confused with all the 10gAS options there are to
    install to just run 10g Forms and Reports and setup
    OracleAS 10g with the load balancing features.
    So I just need to install OracleAS Forms and Reports
    Server if I am just installing Forms and Reports with SSL.
    But if for Load Balancing Oracle 10g I need to cluster
    just Reports 10g? I thought I would need OracleAS10g
    installed on my two Windows servers and somehow cluster
    or let the two know they are the same web page handling
    the incoming requests? I do know about Apache redirct. Is
    that an Apache feature and is it covered in an Oracle
    documentation? They did not cover it in class either.

  • Testing Forms Services availability with Hardware Load Balancer

    I have posted a question about load balancing to a group of application services running Forms Services here on the Forms forum but have had no reply:
    Forms Services availability checking for BIGIP Load Balancer
    My basic questions are:
    a) What do people recommend for load balancing Forms ... least connection, round robin ... ?
    b) Do people use http://server:port/forms/frmservlet?ifcmd=status or have some of you used something else?
    My reason for the question is we had a Forms Services failure that was not detected by the ifcmd servlet as the HTTP side of things was still working. This meant that the BIGIP load balancer sent everything to the failed server as it had the least connections. So basically no-one could logon.
    I've raised an SR with Oracle but they recommend the standard URL above. Has anyone else had a problem like this and if so were you able to fix it?
    Regards,
    Philippe

    Well SR followed up and it looks like the only course of action is to use the standard HTTP check: http://server:port/forms/frmservlet?ifcmd=status ...
    ... unless that is you want to do some serious customisation. Oracle don't support any other form of checking.
    I'm guessing from the lack of responses to this thread that this hasn't been an issue for anybody else ... ???
    Any thoughts/suggestions really welcome as we go into production in 4 weeks.

  • Forms Services availability checking for BIGIP Load Balancer

    We are load balancing across a number of 10.1.2.2 Forms servers using a BIGIP load balancer. Currently our load balancing is done based on which server has the "least connections" to the BIGIP. So far we have been using the following test URL to allow BIGIP to check the availability of the Forms Services on each server.
    http://server:port/forms/frmservlet?ifcmd=status
    This works well however it only checks through to the HTTP level within Forms Services. We encountered a problem when the Forms Services failed to work on a particular server however the above URL showed that everything was OK. The effect of this was that all new users attempting to login were directed to the failed server as this server had the "least number of connections".
    After raising an SR with Oracle they advised that the forking of runtime processes had probably failed and this was not detectable by the load balancer with the above URL. So they have recommended a number of options for checking the status of the Forms Services. These are:
    a) http://server:port/forms/frmservlet
    This loads the default Form and therefore by definition tests the forking of runtime processes. However BIGIP is unable to automatically process the information to distinguish whether the service is up or down. Oracle recommended that if using this method we would need to customise BIGIP to handle the various FRM-xxxx error codes.
    b) http://server:port/forms/frmservlet?userid=scott/tiger@YOURDB&form=yourtestform.
    fmx
    Even more thorough would be to actual log on to the database using a test form as above.
    My question is does anyone out there have experience in checking Forms Services availability using these last two methods as I'm not sure how to customize the load balancer so that it can handle the output of these URLs. Also when using the original URL is it normal to load balance using a "least connections" method or do people out there use a different algorithm.
    Thanks for any help/advise that you can give.
    Regards,

    Well SR followed up and it looks like the only course of action is to use the standard HTTP check: http://server:port/forms/frmservlet?ifcmd=status ...
    ... unless that is you want to do some serious customisation. Oracle don't support any other form of checking.
    I'm guessing from the lack of responses to this thread that this hasn't been an issue for anybody else ... ???
    Any thoughts/suggestions really welcome as we go into production in 4 weeks.
    a) What do people recommend for load balancing Forms ... least connection, round robin ... ?
    b) Do people use http://server:port/forms/frmservlet?ifcmd=status or have some of you used something else?
    Thanks,
    Philippe

    I am having some problems trying to load balance with Oracle Forms, Discoverer and reports Oracle Application Server Release 10g (9.0.4.0.2) and I was wondering if you could help. Has any one ever got this to work consistently? We are an ERP product written mostly in forms (904) and are trying to implement are largest customer there performance issue so we need the load balancing to work. Will also accept other recommendation as cost effective as solutions.

    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 ;)
