Installation Trouble with Oracle BI Discoverer Desktop and Discoverer Administrator 11.1.1.3.0

Hi All,
I'm having installing this software on my Window's 8.1 64-bit machine. I'm going to Disk1 > Install > Win64 > setup.exe. The Oracle Universal Installer shows up, passes the swap space and monitor checks, and stays on "Preparing to launch Oracle Universal Installer from C:\Users etc.... Please wait ..." for a few seconds. It then promptly closes and does absolutely nothing. I've tried the setup.exe from the Win32 bit folder, and that opens perfectly fine (unfortunately mines 64-bit). I've tried running as Administrator, in compatibility mode (all of them), and even updated Java. Does anyone know of a solution?
Also, I have a 32-bit Windows XP virtual machine installed, and when I tried it there, I encountered the same problem. This time with the 32-bit setup.exe.
Thanks,
Neville

Oracle discoverer Administrator and Desktop 'Invalid Username/Password

Dear all,
None of my users can login to Oracle discoverer Administrator and Desktop. It gives invalid username and password. What could be the problem?

Pl post details of OS, database and Discoverer versions. Is this EUL for an EBS database ? If so, are users checking the "apps user" check box on the login page ?

Oracle Portal and Discoverer Integration

Oracle Portal and Discoverer Integration
We're trying to integrate Discoverer with Portal unsuccessfully.
We made many things in accordance with oracle's documentation until add discoverer portlets (worksheet and list of workbooks) in a test page.
In view mode, the worksheet portlet shows the error:
"The portlet has not been defined. The publisher must define the portlet by clicking on Edit Defaults for the portlet on the edit mode of this page. Please contact the publisher of this page."
We think we have to edit properties before. Is this? Anyway edit worksheet portlet crashes between step 1 and 2. The error is: "The listener returned the following Message: 500 Internal Server Error".
We have a public conection created in EM and a discoverer application which can be viewed using plus or viewer.
Furthermore, it's not possible delete the added portlets neither the page that contain it. The error at delete is:

Hi there,
Have you applied any patches to 9ias since it was first installed? We had the same problem and had to apply a couple of patches to get the portlets working.
1. Apply the 9.0.2.53.16 one-off patch for Oracle 9iAS Discoverer which takes Discoverer up to 9.0.2.53.16. This patch appears to be password protected and you need to get someone at Oracle support to give you a password.
2. Apply the Discoverer Portlet Provider: 9.0.2.53.00c patch (patch no. 2595444) which gives you a new discportal.xsl file that actually works. It's this second step that solves your problem but you need to do step 1 before this. This is password protected as well.
3. As you've upgraded Disco on the server to 9.0.2.53, you'll need to upgrade Disco Admin & Desktop within your 9iDS installation using patch no. 2555265. This is because Disco 9.0.2.53 uses an upgraded EUL that Disco Admin & Desktop need to be patched to use.
This was the course of action Oracle support advised us about nine months ago. Of course they may have released a further patch to Disco that does 1 & 2 in one go, but we regularly carry out steps 1 and 2 on servers we use and we can use the Disco portlets successfully.
Hope this helps

How to get the Report Names which use a Folder in Discoverer Administrator?

Hello All,
How could I get which Reports in discoverer Desktop are using a particular folder in Discoverer Administrator?
Or
How to know which Discoverer Desktop Reports are being derived from a folder in Discoverer Administrator?
We have Oracle 9i DS installed and have a Custom Folder Created in the Administrator, and want to know exactly which Reports/Workbooks are using that folder?
Thanks in advance :)

Well Abhijit,
The eul workbooks have been created by oracle specifically to analyze your eul and make your work easier!. So, I prefer this way to view the information about my eul in a report format in the desktop. Try it! you may like it.
If you want you can follow these steps:
Run the script called eul5.sql located in <discoverer_installation_path>\discoverer\util in the user who own the eul in the database.
Then import the eul5.eex file located at <discoverer_installation_path>\discoverer\ in the discoverer administrator.
Then login into desktop and open the reports in the database, you can see a report called[b] EUL Workbook Management. Open that and goto the sheet named Workbook Dependency - Folders & Items Lookup. I think it the last but one worksheet in that workbook.
Hope it helps you!

Creation of a Custom Folder in Oracle Discoverer Administration Edition

Hi
Could anybody help me in solving this problem while creating a Custom Folder in Oracle Discoverer Administration Edition ?
My Requirement is :
I Connect to EUL_US/EUL_US@<HOST_STRING> under Oracle Discoverer Administration Edition.
I selected a Pre-Defined Business Area Eg. General Ledger
There i created a Custom Folder by Name Test Custom Folder
The Query which i used in my Custom Folder is
SELECT NAME FROM GL.GL_JE_BATCHES
When i Used this Query it says Table or view does not exist.
The Folder is getting created but without a Query.
I am not able to preceed further.
Any Help would be appreciated
Regards
Nakul Venkataraman

Hi Nakul, you may be running into a problem with the sql for your custom folder. For some reason Discoverer Admin will allow you to create a custom folder with sql, but then if you change it and it has any advanced sql, i.e. grouping sets, analytic functions etc., you probably receive an error.
An option is to create a view using the same sql and create a folder from the database using this view.
Hope this helps.
Brent.

Portal integration with E-Business and Discoverer 10g

Hello Everyone,
We have a R12 integrated with SSO/OID. We also have a standalone Oracle BI Discoverer 10g. We want to implement Oracle Portal here. One of the requirements of this project is to have a common home page for both E-Business Suite login as well Discoverer access. Right now E-Business Suite login is seperate and Discoverer home page is seperate (because it comes from a Standalone installation)
1) What are the benefits of having AS Portal 10g for end users ?
2) To begin with, we would like to go with the minimum portlets.
3) Is it possible to have a common home page for both E-Biz access and the Discoverer acess after Portal integration ?
4) Do you have some screenshots of how things look after Portal integration
-Thanks
Srinivas

Hi,
take a look in metalink Note:313418.1. :
"Using Discoverer 10.1.2 with Oracle E-Business Suite 11i"
Look in section 6 - post installation.
Follow the steps and have a very good luck.

Discoverer Administrator 11.1.1.3.0 EUL Export Doesn't Export All Functions

Using Discoverer Administrator 11.1.3.0 against an Apps EUL. Logged in with an Apps User ID with administrator privileges. When I export the EUL using File | Export "The entire End User Layer", I am shown all of the objects that will be exported. Everything is listed, including all of the registered functions.
However, when the export completes and I am shown a list of the objects exported, the only registered function shown as being exported is END_OF_TIME. Checking the export file verifies that this indeed is the only function definition that was exported.
If I start the export again -- logged in as the same user -- and choose "Selected objects in the End User Layer" , choose "Functions", and select all of the registered functions, they ARE all exported.
Why is this happening?

How to start Discoverer Administrator on Applications 11i Installation

What privileges should be grant to Discoverer Administrator

Hello,
We are going to install Discoverer 4i to access our 10g database. What privileges do I need to grant to the Discoverer Administrator? Thank you.

Hi,
At the very least the Discoverer Administrator should have Administration privileges with Format Business Area, Create/Edit Business Area and Set Privilege. This can be given directly to the user or through a role/responsibility.
Hope that helps,
Rod West

Refresh EUL in Oracle Discoverer Administrator using command line

Hi there! I wonder if there is a way of refreshing the EUL business folders of Discoverer Administrator using a command line, so that it could be done through a batch file process.
Many thanks in advance

What do you mean by refreshing the EUL business folders? The definitions of the EUL are updated whenever a workbook/worksheet/business area/hierarchy/ any other object inside the EUL is changed/added/deleted. Also, the contents of your EUL are updated whenever summaries are refreshed (either manually or on a schedule), or when scheduled workbooks run and their contents stored inside the EUL.

Oracle Discoverer Administrator 'OUT OF MEMORY'

Hi ,
I'm trying to include a case statement in the custom folder based on a query.when I include the case statement in the SQL query and click Validate SQL button i get error 'out of memory'.
can anyone plz help me with this.
thanks

Hi
The Out of Memory is not 100% related to the amount of memory you have on your machine. There is an internal cache that it is working with and this is controlled from within your system registry. These settings can be found in [HKEY_CURRENT_USER]\Software\Oracle\Discoverer 10\Application and they are called MaxVirtualDiskMem and MaxVirtualHeapMem and these are typically set to the amount of memory on your PC or even higher where 512000000 equates to 500 MB. I have rarely seen making a change to these have any impact but you can always try.
As a test, try using the Admin command line interface to do what you want. I have seen exports, as mentioned by Russ, fail using the application but work just fine when called from the command line.
You seem to be saying when you run the query yet in your question you say running in Discoverer Administrator. You cannot run a query in Administrator so are you saying that you get this issue when running the query in Desktop or in Plus? For Desktop you can try altering the MaxVirtualDiskMem and MaxVirtualHeapMem, whereas for Plus these will have to be changed in the pref.txt for the application server.
You can also try increang

HOW TO CONNECT ORACLE BI DISCOVERER ADMINISTRATOR 10g

Hi,
My question is HOW TO CONNECT ORACLE BI DISCOVERER ADMINISTRATOR 10g. I know how to connect PLUS and VIEWER using a URL. Do i need to install Discoverer Admin. separately on my local machine.
This is very urgent... Please reply.
Thanks in advance for your time and answers.
Jay

Discoverer Administrator is a client side tool, you must install it on your machine or even you can install discoverer administrator in your server but you must connect through a connection string which you must enter in your tnsnames

AS 10g SE now includes Reports and Discoverer?

I've read some articles about the "new" AS that it has been "re-packaged" (licensewise) and that the BI stuff like Reports and Discoverer are included in the Std Ed. Also (in the FAQ I think) that some EE stuff has been moved "down" to SE - sounds promising! But I have not been able to verify this... Anyone out there?

I urge Oracle do the same for Discoverer.
We have been using Discoverer since 3i. This year, we had some people on 3i still and some on 4i. We went through the conversion to 4i and no one is using 3i at all now. These people are very used to how Discoverer works. They are used to using database authentication and security to workbooks.
The Infrastructure can store connection information for each user. By default, it stores connection information in cookies on the user's machine but you can configure the Infrastructure to store this data for you. The Infrastructure also stores metadata for Discoverer Portlets (Portal required).
So that is it. If you are not using Portal nor care about storing connection information in a database, then why even have the Infrastructure for Discoverer? Just like Reports and Forms, if you aren't using SSO or Portal, there is no need for the Infrastructure and Oracle should provide an installer to let you install Discoverer without having the Infrastructure sitting there.
Here is the doc on Metalink that explains what the Infrastructure does with Discoverer 9i.
http://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=224871.1
I also spoke with John Entenmann at ODTUG in Miami this year and asked him if Discoverer works and is supported in an install without the Infrastructure. He agreed that if you are not using Portal or SSO, you don't need the Infrastructure with Discoverer 9i.
Now Oracle needs to support Discoverer customers in the same way they are going to support Forms and Reports customers by providing a more reasonable installer that doesn't require the Infrastructure to be installed first.
