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).

  • Load Balancing Oracle Reports in Report Server

    We have 3 Apps box in the production clustered environment. The load balancing is taken care of and when users are trying to connect to the production, they provide the virtual name and Apps server get them connected to any one box. However, when any user try to run a report from the menu, we have to specify the exact report server name. For eg like this
    http://xyz.dc4.pqe/reports/rwservlet?*server=rep_dtgadmapps103_AS10g_mtier*&report=/apps/dis/bin/DISRATN.rep&desformat=pdf&destype=cache
    Is there any way to configure a virtual report server name, so the Apps server could take care of the load balancing. Otherwise all the reports are getting flocked to a single server and the queue gets long.
    Thanks in advance.

  • Can we run oracle Forms 5 Application with 10G in Client/Server?

    Hi All,
    Can we run oracle Forms 5 Application with 10G in Client/Server
    Mode?
    Regards
    Gaurav

    In theory you can run it 2 tier - which means that you have the client (the machine the user is sitting at) being the same machine in which the forms application server is running. So yes. But specifically, we don't support a client server runtime anymore. 6i was the last version.
    With 10g you will be running through a browser.

  • Load  Balancing Oracle BI Presentation Server with OC4J

    Hello All,
    Is there a way to perform Load Balancing Oracle BI Presenation Server the way we do with IIS (defining in ISAPIConfig.XML file)?
    I am looking some pointers towards Clustering/Load Balancing Oracle BI Presentation Servers using OC4J not IIS.

    Thanks , the Oracle BI Presentation Server is running now ,but still the oc4j display the below error :-

  • 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...

  • Load: class oracle.forms.engine.Main not found Stuck at loading Java Applet

    Hi there
    I have recently installed App Server 10.1.2.0 on a new machine.
    Copied all my forms to an appropriate directory. Set up formsweb.cfg to allow them to run and have attempted to run them.
    Unfortunately I get stuck at the Loading Java Applet screen, and in the status bar at the bottom it says :
    load: class oracle.forms.engine.Main not found
    I have taken a look at the Java Console, and the 2 things that jump out at me are that it appears to be looking for a forms90 directory, which seems odd since I am using App Server 10.1.2.0.2 and Forms Builder 10.1.2.0.2 meaning it should be looking in a forms directory not forms90 directory shouldnt it ?
    And also, it mentions class with no proxy, so on looking around the forums it has been suggested that put the proxy details into jinitiator, which I have done, but this has made no difference either.
    Can anyone suggest anything else please ?
    Java Console log follows.
    Thanks a lot

  • Oracle 9i R1 application server With Windows 2003 server

    Hi all,
    I am Getting error (Web Forms can install only Windows NT/2000) When installing Oracle 9i R1 application server in Windows 2003 SP1.
    is any specific setting or workarounds available to install in Windows 2003 Server?.
    Abk

    setup.exe -ignore sysprereqs this may work because it will detect that you dont have the appropiated OS, but it will ignore under your responsability and keep installing.
    Also you may try to modify the oraparam.ini in the install folder, and add some lines for the Windows version that you have, but this is more difficult, because you should use the exact name of the Version in order to pass this check.
    Regards.

    Hi,
    1st solution - use DOI (desktop office integration). This way you can open Adobe, Microsoft, and others application documents directly in the SAP windows. See SAP document how to do it. It's not a little work, but it should fulfill your requirements.
    2nd solution - share the folder with the PDF documents and then with shell command (start
    server\folder\xxxxxx.pdf) at the front end access it and start the associated application at the frontend. I don't recommend this one, sharing folders at the appl.server is a security threat...
    You know about the points and useful answers...
