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.

santosh says November 9, 2006

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

Atul Kumar says November 9, 2006

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

Atul Kumar says November 9, 2006

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,

Atul Kumar says November 10, 2006

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

Atul Kumar says November 10, 2006

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”

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

Atul Kumar says January 23, 2007

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

Anonymous says January 29, 2007

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

Atul Kumar says January 29, 2007

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 .

Raise your issues / doubts at forum dedicated to Apps DBA’s

abhinethra says February 6, 2007

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


Atul Kumar says June 28, 2007

which PDF files ?

qAnand says July 23, 2007

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

Atul Kumar says July 23, 2007

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 .

tkj says October 11, 2007


I want to learn discoverer.

I am having oracle 9i database and downloaded and installed OracleBITools10g from Oracle.i.e OracleBIDiscoverer Administrator and Oracle Discoverer Desktop, I don’t know how to configure it with my Oracle 9i Database and use it. Please any to help me?


Atul says October 12, 2007

Hi Tkj,
I would say go for BI EE (Business Intelligence Enterprise Edition , Superseeding Disco) and to install server and related documentation at

tkj says October 12, 2007

hi Atul,

Thanks for the reply. I have a question, can i work configure Discoverer with my 9i oracle database and create EUL? otherwise should I have to have Oracle Apps , and on top of it only EUL can be created?

please help


Atul says October 13, 2007

You can use existing database and on top of that install discoverer server which you can use from disco client like OracleBITools and there is no need to install 11i in that case.

Installing BI server in existing database is advanced installation so I’ll suggest you install Oracle Application Server ( with option as BI or stand alone Disco server , I am going to cover BI EE installation on this site in one or two weeks so stay tuned.

Could you pls help me.

jsethi says April 18, 2008

When trying to login to Standalond Discoverer 10g as sysadmin, you get invalid username/password.Try loggin in as

sysadmin:System Administrator

And the connection will go through.



Paul says September 9, 2008

Hi Atul & Team,

When you copy .dbc file from another discoverer home (instance) and make necessary changes as per the new instance, in case it is bad or not correct, is it necessary to bounce the discoverer services?
What services exactly we need to restart?
For example, opmnctl , etc..

Sincere Thanks.

Nagarajan says December 13, 2008

Is Discoverer Plus in 10g same as Discoverer Designer present in the earlier version (4i)?

Jagdeep says December 13, 2008

No. The bouncing of Discoverer services is not required. The connection is very much instant.

siva says June 30, 2009

We want to upgrade the current reporting server to Windows 2008, but are unsure if we install Discoverer on it, will it connect to the legacy 9i database???
