    Discoverer 10g & Oracle 11i Configuration Steps
    Wednesday, November 08, 2006
    Register for R12 upgrade
    If you are reading this post directly then visit my previous posts on discoverer basics & overview with Apps at

    Lets start today with broad level Steps to Install & configure 10g Discoverer with Apps 11i , in end you can see metalink note & other references.
    Please Note that Steps mentioned here are specifically from version

    1.Install 10g Oracle Application Server Release 2 i.e.
    2.Copy DBC file from $FND_SECURE(E-Business Suite Tier) to $ORACLE_HOME/discoverer/secure(Discoverer Home Installed in Step1)
    3. Update tnsnames.ora in DISCO ORACLE_HOME installed in Step1 to point to E-Business Suite 11i Database
    4. Migrate your EUL (End User Layer) from 4i to 10g EUL (Please Note upgrade from EUL3i to direct 10g is not supported , you have to first upgrade eul to4i & then to 10g)
    5. Select JVM for Disco Plus (you can Oracle's Jinitiator or Sun Java Plug-in)
    6. Apply Necessary Apps Patch for compatibility Issues (For list of patches check Metalink Note mentioned below)
    7. Change Profile options to point to 10g Discoverer from 4i

    All these Steps above are compulsory steps , I have not mentioned Optional Steps like Single Sign On Server configuration and generating Business Layers. Also steps mentioned here are configurations related to Apps DBA's perspective for functional steps refer to document mentioned below.

      does installing 10g Oracle Application Server Release 2 i.e. itself is installing discoverer? what would be the URL to access discoverer then?

    • At 9:00 PM, Blogger Atul Kumar said…

      Yes Santosh,
      when you install Application Sever (With Middle Tier Option as BI & Forms) this will install Discoverer & rest other steps are configuring it with E-Business Suite . That's why I mentioned in my previous post that Upgarding Discoverer is not supported but its New Install & Upgarde only EUL

    • At 9:07 PM, Blogger Atul Kumar said…

      Sorry I forgot to mention URL




      where hostname & domainnanme are machine name & domain name on which you installed 10g AS & port number is port you selected at install time defualt 7777

      though you can change these hostname & port number to your desired value

      Hi Atul,
      Well done on the website!

      I have installed on the same physical server as my current 4i install. For the purpose of testing and parallel runs etc this was the only course of action I had open to me. Oracle recommend not to do this. Both are functioning fine at the moment with the 4i and 10g tables located in the same schema. I can't fine out why Oracle warn against this (from Metalink etc).

      Do you have any ideas?

      Many thanks,

    • At 10:48 AM, Blogger Atul Kumar said…

      first of all congarts for configuration.

      I dobn't see any document where Oarcle mention not to install discoverer 10g on same machine as discoverer 4i but they say you can't share Oarcle_Home.

      Could you please point me oarcle doc which say not to (or not recommended) to install 10g Discoverer on same host as on 4i discoverer .

      Once again thanks for sharing this info with readers , It will really inspire them to go for Disco 10g R2 wiith Apps

      "Installing Oracle Application Server 10g with Oracle E-Business Suite Release 11i. Note:233436.1’

      ‘Existing Discoverer 4i content, including workbooks and End User Layers, can be easily upgraded to Discoverer 10g. It is strongly recommended that Discoverer 4i and 10g be installed on separate physical servers; see the Oracle Application Server 10g Release Notes for your operating system platform for more details.’


      lists the Application Server 10g coexistence restrictions.

      I have yet to see an explanation why they cannot coexist. There is a suggestion that this may have something to do with the visibroker but I am not sure.


    • At 1:00 PM, Blogger Atul Kumar said…

      Thanks for pointing that out & docs for that.

      I will also try to find reasoning behind Oracle's recommendadtion that "Discoverer 4i and 10g be installed on separate physical servers"


    • At 5:42 PM, Anonymous Anonymous said…

      Hi Atul,
      Thanks for publishing a blog on Discoverer. DO you have any estimate on the activities performed during upgrade like:-
      1. Migration of existing EUL to 10g

      2. Regenration of business views

      3. Import of Discoverer content using

      4. Refresh Discoverer EUl


      the size of my EUL Tbs is around 850 M.

      Regards, VVS

    • At 6:43 PM, Blogger Atul Kumar said…

      Hi VVS ,
      Is this from 3i or 4i ?

    • At 11:26 AM, Anonymous Anonymous said…

      Hi Atul,
      This is from 4i to 10g.
      Also, I want to know how it is possible to maintain different URL's for 4i and 10g, if we want to put two discoveres's for one database, as I did not see anything in the xml file, which will facilitate the same.

      Thanks in advance,
      Regards, V V S

    • At 12:46 PM, Blogger Atul Kumar said…

      VVS ,
      EUL upgrade should be around 1 hour or so (Depends on your server configuration as well).

      You can have two different URL's via Profile Options.

      You have to set one URL at site level & other one at server level .

      Please any one tell me the location of PDF FILES ON MIDDLE TIER


    • At 4:28 PM, Blogger Atul Kumar said…

      which PDF files ?

    • At 10:57 AM, Blogger qAnand said…

      Hi Atul,
      You directed me from Application Server section to this discoverer section.
      As shared in my previous post (AS section),
      I am on 11.5.10 (9iAS)
      I have created my EUL using Discoverer 10g.
      But because of compatibility issue I am not able to use Discoverer Plus/Viewer with 10g EUL
      Can you suggest what would be the steps?
      I understand from your post that AS cannot be upgraded from 9iAS to 10g in Apps environment. Can you please elaborate?

      Thanks again

    • At 11:09 AM, Blogger Atul Kumar said…

      11.5.10 by default comes with eul4 so install standalone 10g Discoverer on seprate oracle home and chnage tns in this oracle home pointing to your 11i database. and use disco URL using new 10g AS ORACLE_HOME . Check 10g Disco configurtaion with 11i metalink note for more information on how to do this .

    • At 6:43 PM, Anonymous Anonymous said…

      Hi Atul,

      1) I have created the .dbc file in Discoverer/Secure
      2)updated tnsnames in discoverer
      3) I have created the EUL using eulapi

      Refering 313418.1
      I am into step 7 of Note, configuring the jvm for disco plus?? should I ?

      Section 6 : Postinstallation Tasks?

      I want to enable the workbook(standard) in the Discoverer viewer/Plus

      There seems so many steps, which I can exclude?? Please guide...

      Is it possible in discoverer10g to change parameters RowFetchLimit, RowFetchLimitDisabled in pref.txt file globally for all users.


    • At 9:32 AM, Anonymous Anonymous said…

      Hi Atul,

      Thanks for doing this great work. I have a doubt about discoverer10g. Is it possible to change parameter RowFetchLimit, RowFetchLimitDisabled for all users in file pref.txt file. We want to disable these parameters for all.


    • At 11:58 AM, Blogger Anuj Malhotra said…


      I am working on Discoverer 10g and Now I have to work on configuration files as well. Can you tell me what all we can do with the Discoverer Configuration files and how we can access those files. I refered the Documentation and found that We can do Viewer and discoverer Plus Customizations in terms of Color font etc , Do you have any good documentation on it and can you guide me on..

      Hi Atul,

      How do i know that the discoverer is used and has EUL's. In the installtion note 313418.1 under the section "Migrate your existing Discoverer End User Layers to Discoverer 10.1.2." he says ""If you do not have an existing Discoverer 4i or 9.0.4 End User Layer, skip this step ""

      Check with your discoverer developer or end users.

      Multiple Oracle Discoverer version on same system

      Is there a way we can have both Oracle Discoverer 10 (web-based) and Oracle Discoverer 4 (existing version) installed on the same production server to allow us to deploy new reports in the web version while still supporting the older existing reports?
