How to buffer data in Oracle 9i Application Server?

We need to know, when using OAS(Oracle Application Server), if there is a way to buffer data. If, not, is there an alternative? OAS is being used in the generation of reports. For large reports the PC will sit, with essentially a blank screen, until all of the data is retrieved and formatted. Only then is the report displayed. This can take minutes (or longer). What we are looking for is a way to retrieve some of the data and display it, while the rest of the data is being retrieved in the background.

The following error comes when i try to access it
"Invalid protocol verification, illegal ORMI request or request performed with an
incompatible version of this protocol"You are using the rmi port of oc4j in your URL. Instead, your should use the http port. Yes, of course, the http port.
The initial ports are defined at ORACLE_HOME/install/portlist.ini ... if you reconfigure (say, by changing the ORACLE_HOME/Apache/Apache/conf/*.conf or the ORACLE_HOME/Apache/conf/* files), the portlist.ini will not be updated. Well, you can always use "opmnctl status -l" to find the http port.

    No, you need the Reports Server (as part of the Application Server or Weblogic, depending on your version).
    I try to save the report, it's saved as .jspThat depends. You can save it as a .rdf file too (so called Paper Layout). I think this option is used more often.

    Telling us that you are using 11.1 helps. But it is far from a complete description of the environment. What edition of the database are you using? What options are installed? What Enterprise Manager packs are licensed? Is any of this changable? Could you license another option for the database or another pack for Enterprise Manager if that was necessary?
    What does it mean to you to "mask data"? Do you want to store the data on disk and then mask the data in the presentation layer when certain people query it (i.e. store the patient's social security number in the database but only present ***-**- and the last 4 digits to certain sets of employees)? Do you want to hide entire fields from certain people? Do you want to change the data stored in the database when you are refreshing a lower environment with production data? If so, do you need and/or want this process to be either determinisitic or reversable or both?

  • How to pull data from oracle GL to planning

    Hi all
    Can one suggest me how to pull data from oracle GL in to hyperion planning(we are using hyperion planning 9.3 with limited licence for analytic services). i guess we can use HAL ..any thing else
    any help is appreciable
    regards
    M.V

    Hi
    I appreciate for your response. Yep you are exactly right it is data only, but I do have a problem these people have their licence of limited version of Essbase.
    Let me give you the information of their licence agreement.
    The licence for the hyperion planning- sytem9 programs includes a limited use license for both the hyperion Essbase- system 9 and hyperion Financial reporting - system 9 programs. Such limited use license means that the hyperion Essbase- system 9 and Hyperion financial reporting -system 9 programs may only be used to access data from the Hyperion planning -system 9 program.
    Specifically, the hyperion essbase- system 9 program cannot be used to create Essbase cubes that do not contain data used by the Hyperion planning- system 9 program and the Aggregate storage option component of the Hyperion Essbase - system 9 program may not be used.
    1) what it(licence agreement) really means - can you install Essbase, if not how can you create dimensions dynamically using planning.
    2) Is it possible without Essbase as far as I know its not possible
    3) are we going to face any issues with this licence.
    4) Is it possibe to pull data with planning
    I appreciate if any one resolve this issue
    regards

  • How to make data flow from one application to other in BPEL.

    Hi All,
    I am designing work-flow of my application through BPEL(JDeveloper), I am making different BPEL projects for different functions, like sales manager got the order from sales person and sales manager either approve it or reject it, if he approve it it goes to Production manager and he ships the goods, now I want to keep sales person, sales manger,production manager in seperate BPEL files and want to get the output of sales person to sales manager and sales manager to production manager please help me in dong this.
    I was trying to make partner link in Sales manager of sales person and getting the input from there. I dont know this is right even or not, if it is right I dont know how to make data flow from one application to other.
    Experience people please guide.
    Sales Person -----> Sales Manager ----> Production Manager
    Thanks
    Yatan

    Yes you can do this.
    If you each integration point to be in different process, you have to create three BPEL process.
    1. Create a Async BPEL process 'A' which will be initiated when sales person creates the order.
    2. From BPEL process 'A' call a ASync BPEL process 'B' which has the approval flow. Depending on the input from process 'A' the sales manager will review the order in workflow and approve or reject and send the result back to process 'A'.
    3. Based on the result from workflow, invoke the Sync BPEL process 'C', where you can implement the shipping logic.

  • How to Deploy SSRS Reports(Sql Server 2008 R2) into Oracle Weblogic Application Server

    Hi Friends
    One of my project requirement is Developing reports by using SSRS and deploying the reports into Oracle Wblogic Server
    Could you please give me a Steps where we need to configure.
    Regards
    Hasthi.

    Hi Hasthi,
    As per my understanding, I think we couldn’t directly deploy the SSRS report to Oracle Weblogic Application Server. We can deploy report to report server and SharePoint library. And we can display report to some applications, for example, windows application
    and web application. Sorry for that I am not familiar with Oracle. So if your Oracle Weblogic Application Server support those Visual Studio application, then we can use report viewer control to display report in application. For more detail information about
    report viewer control, please refer to the following document:
    http://msdn.microsoft.com/en-us/library/ms251671.aspx
    Hope this helps.

  • Oracle 10g Application Server Stand By Creation

    Hi all ,
    I am newbe for oracle 10g application server . I need to know that how to create stand by applicattion server and how to make the report server name same as production server so that in case of emergency i can quickly shift on stand by.

    What we did was build the second server and powered it down. If our main data server loses power we start it up. The two servers are never up at the same time.
    To change the report name :
    1. Backup the file $ORACLE_HOME/sysman/emd/targets.xml.
    [oracle@tasias02 emd]$ pwd
    /u01/app/oracle/product/midtier/sysman/emd
    cp targets.xml targets.xmlbackup
    2. Modify the file targets.xml by changing all the occurrences of the wrong reports server name by the correct one.
    i.e. Replace rep_old with rep_new (4 places - changes)
    Copy the conf file as follows: ( this will named different from system to system )
    cp /u01/app/oracle/product/midtier/reports/conf/rep_old.conf /u01/app/oracle/product/midtier/reports/conf/rep_new.conf
    run this script:
    /u01/app/oracle/product/midtier/bin/addNewServerTarget.sh rep_new          (change rep_new to new report server name)
    3.Update the changed configuration .
    /u01/app/oracle/product/midtier/dcm/bin/dcmctl updateconfig -ct opmn -v -d
    /u01/app/oracle/product/midtier/dcm/bin/dcmctl resyncinstance -v -d
    4. Restart the Application Server Control Console
    /u01/app/oracle/product/midtier/bin/emctl stop iasconsole
    /u01/app/oracle/product/midtier/bin/emctl start iasconsole
    In the file:
    /u01/app/oracle/product/midtier/reports/config/reportsConfig.properties
    Change the Reports_Server_Name setting from "rep_old" to "rep_new" (change rep_new to new report server name)

  • Oracle 9iAS Application Server  Rel 2

    Just installed Oracle 9i Application Server and Infrastructure. Tried testing a very small Forms-based application with just a welcome screen and a database login screen. Did nothing after. Here is a snapshot of a situation running out of hand with respect to the system resources and how the resources are being swallowed by 9i services. CPU utilization is at 100% all the time. The following data is from the Windows Task Manager output.
    Image Name PID CPU CPU Time Mem Usage Page Faults I/O Reads I/O Writes
    opmn.exe 1000 48 7:28:27 5,460K 6,717 39 253,367,324
    opmn.exe 2544 45 8:20:30 7,136K 12,390 39 198,559,189
    vsmon.exe 1844 02 0:09:06 5,916K 48,729 9,797,444 112
    Why are these programs racing out of hand. Why are the I/O Reads and Write so high? These values are rapidly increasing even as I am writing this message.

    Sanjay,
    Thank you for your input. Will try your suggestion and see if I can get service stability with just the options you mentioned. In my case, I had to stretch to a complete install because I wanted to use the Forms and Reports services. These are now under the ...ProcessManager.. service in Windows 2000. Unfortunately we don't see separate services for Forms and Reports anymore in Rel 2. I still don't understand why we should go thru a Infrastructure install if I don't need them for Forms and Reports. It is all cooked very odd this time in Rel 2.
    I didn't have to manually set up tnsnames and listener configurations. I am not sure why it happened to you with a basic install.
    Not having a complete picture of the install process is a big mystery. Least of all, we have some idea of the Windows services in Appendix D of the Install Guide. Check the following link.
    http://otn.oracle.com/docs/products/ias/doc_library/90200win_otn/install.902/install/toc.htm

  • In Oracle 9 Application Server can we create multiple instances???

    Hi I need one help this is regarding to the oracle 9 application server in this can we create the multiple instances??
    my application was already developed and currently it is working with one instance for this i need to create the another one more instance which is same as existing and my application is web application developed in Forms6i and the db is oracle 9i my requirement is to create one more instance what are all the configuration files need to be modified and please give this info ASAP....

    It is still not very clear. What do you mean by creating "one more instance of the same application in the same application server"? By "application" do you mean another instance of OC4J in same Application Server Instance? If yes, you can do that. I mean you can create another OC4J component in same Application Server Instance without doing another installation. Refer this for details:
    http://download.oracle.com/docs/cd/A97329_03/core.902/a92171/config.htm#1010793
    If you are looking to create another Application Server Instance out of same installation/binaries (i.e. Oracle Home) than the answer is no. You can not create multiple Application Server Instances out of one Oracle Home. You will have to do another installation in a different Oracle Home and that's how you will get another Application Server Instance.
    Hope this helps.
    Thanks
