Discoverer Viewer - necessary components

Are the Oracle Internet Directory and Metadata Repository necessary to run Discoverer Viewer?
I'm having trouble connecting to my database locally through Viewer and am wondering if that's the issue. These are not installed.
Thanks

Hi
No these are not required in order to run Viewer. In order to run Viewer you need to have a database account and password, and the correct URL to launch the tool. The server upon which Viewer is running needs to have a TNS Names connection to the database and your Discoverer Administrator needs to have created an End User Layer (EUL) in the database itself, to which you have been granted access.
An attached Metadata Repository opens up public and private connections whereas OID, in addition to the Metadata repository, opens up Single Sign-On.

I cant see the graph in discoverer viewer whith was created in the desktop

Hi,
I need your help!! I have a problem to see a graph in Discoverer viewer. I will detail you the steps that I follow;
It was a difficult calculate report to results by Discoverer so, I create a view in the data base which show 3 field, Periodo(number) which is a union whit other field from other folder, State(varchar), Requirement(number).
From the discoverer desktop y have a crosstab worksheets and a graph, there I can see it without problem, but in the Discoverer viewer I can see the graph.
I tried to set the worksheets options in “show options” to show me the graphs too, but this options didn’t appeared there. Somebody know what I should have to do to see it?
On the other hand I changed the “show null values show” option since null to empty, and when I wanted to save the change this error appeared;
“Oracle BI Discoverer don’t had to found the necessary values to show the events…”
Thanks for your help!
Regards
Dora

Hi Dora,
The graphs that you create using Discoverer Plus will show nicely in Viewer. Everything you develop in Pluys works in Viewer. They are companion products.
You must realize that Discoverer Plus/Viewer and Desktop are two seperate product sets and they use different techniques for graph creation. There are other differencies between the two that suggests that you need to develop all reports using Discoverer Plus in stead of Discoverer Desktop.
I have experienced workbook created in Plus being destroyed when opened and saved using Desktop. So for a long time I have simply forgotten all about Desktop. If your company is relying on both Viewer and Dersktop I suggest that the time has come to change strategy and technique.
If you need sparring please mail to [email protected]
Good Luck!

Report not working in Discoverer Viewer

Hi,
I'm using Discoverer 10.1.2.1 in conjunction with E-business Suite 12.1.3.
I have a report that runs fine in Desktop or Plus, but when run in viewer (either from the application or from the stand-alone viewer link) it ends with the following error after running for approx 4 minutes:
The application encountered an invalid state.
OracleBI Discoverer Viewer was unable to find the necessary data for displaying the results of this event. Please correct any errors and try again.
I recreated the report from scratch, using the same underlying data, and adding exactly the same items, conditions and sorting. The same responsibilities have been given access, and I verified that the SQL produced in both reports is exactly the same.
However my new report works! From what I can see the only difference is the name and workbook identifier.
Does anyone have any idea what could be causing my error? I have searched for the error on this forum and others but haven't found the answer.
Thanks
Hazel

Hi Hazel
This has come up before and I found this thread that I was involved in several years ago: https://forums.oracle.com/message/3682002
Here's another one, this time relating to static IP addresses: https://forums.oracle.com/message/1199457
There's also a document on Oracle Support: The application encountered invalid state.Oracle BI Discoverer Viewer was unable to find the necessary data for displaying the results of this event" (Doc ID 884965.1)
Also, were you using Portal? I've seen instances where Viewer was unable to run a report that was linked via Portal because the report had changed since it was placed on the Portal.

Oracle Discoverer Viewer will not display in browser

Hi,
I tried using the link below to get to discoverer viewer but it is not working. I can access Oracle Enterprise Manager without any problem.
Could you please help me with that.
Thanks,
Vani
===========================================
Start a Web browser and enter the Discoverer Plus URL containing the fully qualified host name (including port number if necessary) used by your own installation.
For example:
http://machinename.myorganization.com:7777/discoverer/plus
Where:
machinename.myorganization is the hostname and domain on which the Oracle HTTP Server is installed
7777 (optional) is the port number on which the Oracle HTTP Server is installed if the default port number (i.e. port 80) has been changed
/discoverer/plus is the URL command that starts Discoverer Plus

I am using oracle 9iAS on Windows 2000 Professional.
Database is the one created from the Oracle 9iAS CD that holds the 9iAS Infrastructure.
I have tried using both Netscape 7.1 and Internet Explorer 6.
At this moment, I am hosting database, Application server and browser on this test machine.
I am starting to believe that may be I do not have the correct EUL version but I have used Oracle IDs to create the EUL. It is version 5.x.x. I am not at the location so I cannot give the exact EUL version.
Thanks,
Vani

Discoverer Viewer Report in Web

Hi,
I had created the report usingOracleBI Discoverer Plus Version 10.1.2.45.46c & able to visualize the report in OracleBI Discoverer Viewer Version 10.1.2.45.46c.
URL fo accessing the report is as:
http://machinename1:7777/discoverer/viewer
If i try to connect to from another machine (machine2) as
http://machinename1:7777/discoverer/viewer
i'm unable to connect & i get the error page can not be displayed.
Is it necessary to have the URL only with domain name as
http://machinename.domainname:portno/discoverer/viewer
I had already installed OWB, Oracle BI etc. If i had to create a domain then i have install all these & need to work from scratch.
Is there any way to access the report across the internet or web.
Plz do provide a solution for this issue.
Thx in Advance

As long as you can access the middle-tier server where Discoverer Viewer is running, you should be able to run and view Discoverer worksheets.
While it is difficult to even start guessing what the problem might be, if the machine you installed Discoverer on has DHCP addressing, you will run into problems.
Thanks

Discoverer Viewer & Scheduled Workbooks

Is it possible to run a scheduled a workbook and view the results in Discoverer Viewer?

Hi Tim
Well just the way the file is put together, like is it using SID= or SERVER=, does it use SERVER=DEDICATED, do you have one ADDRESS= or multiple?
To make sure everything is right, rename both TNSNAMES and SQLNET.ORA files, then suse Net Configuration Assistant to set up a connection. Then compare that with what you have already and make the necessary changes.
I also noticed that Russ has made a posting concerning a similar error. You should take a look. Its either in here on the Discoverer forum.

Drill Down pop up in Discoverer viewer

Hi
We use Discoverer viewer version 9.0.2.53.0
I have made a drill-down crosstab with three drill-down levels. When I drill in the viewer the pop up box (the one that shows what levels you can drill to) comes up with scrollbars (both horizontal and vertical) and only the first and second level show, I have to scroll to see the third level.
Does anyone know why this is happening and how I can get a pop up without scrollbars (like I have in Plus and Desktop)?

I filed a TAR on metalink for this, here is Oracle's reply, and my reaction to it:
<snip from TAR>
Hi Jens.
I have tested this on both 902 versions and have seen the difference. As this is a change purposely done by Developement in order improve functionality the only way that it can be changed is not through a Tar/bug but by logging a enhancement request. This can be done by you through Metalink.
To log a enhancement request click on the blue button on the left hand side of the screen titled 'News & Events', then clcik on the 'Click here for more ERS information' link - this will allow you to log a enhancement.
I will now suspend this Tar. The status of this TAR is SCL (Suspended by Oracle Support Services). Should you wish to progress/reactivate this TAR please update the TAR via Metalink within the next 14 days. After that period please log a new iTAR stating this TAR number as base TAR if the same problem occurs.
Best regards,
<signature removed>.
New info : "Purposely Done"?
You must be joking.
Could you please explain why they have done this.
I think someone have screwed up here.
Should not be necessary for me file an enh. req. for this.
The popup is hardly usable, as you can't read whats in it. This have to be a
bug.
Please follow this up through the tar.

Can you believe Oracle Developers want the pop-up like this.... ;-o

Eror on discoverer viewer

Hi every one
I have done a Discoverer report .Now the user can not access the worksheet it returns an error saying
"Error :The application encountered an invalid state. - Contact with backend server lost
OracleBI Discoverer Viewer was unable to find the necessary data for displaying the results of this event. Please correct any errors and try again.
Error Encountered"
however r when i log on using my details in her pc it works fine.
I have checked security and privileges have been set up correctly and she is the only one who cant access the worsheet, she can see the report but unable to open the worksheet.

Sounds like it's her in particular.
Therefore, have you checked that:
1. she's allowed to access the underlying database tables / views?
2. she's been given security to look at the business area(s) the report accesses?
Is this against an Oracle Apps environment or a database environment?
Reason I'm asking is that if Oracle Apps, is she going in as the same responsibility as someone who can run the report - and equally if a database environment is she going in as the same role as someone who can run the report?
You could also have her testing the report from your PC as well going in as herself but I'm sure it's the same situation - but just in case.

Discoverer viewer -- export to pdf doesn't retain page settings.

Hi,
The report output in discoverer viewer is much different from that of plus. I am concerned abt the report headers. In discoverer plus, the headers are left, center and right aligned.
But in viewer, every thing is aligned center. How can I get the report o/p (same as that of plus) in viewer??

Discoverer Viewer/Plus does not work with Custom EUL owned by APPS user

I am facing a unique issue with one of my customers. They have a custom EUL named XX_EUL_US and this does not allow connecting through discoverer viewer or discoverer plus.
I have worked with custom EULS before at other customers and this was never the case. I am being told that this issue is happening as the EUL owner is APPS instead of some other user. Is this the case? Can discoverer viewer not be used with EULs owned by apps user?
Please not that the Default EUL in ICX profiles is set to this EUL and no other EUL profiles are set.
Appreciate any thoughts on this.

Hi,
I am not sure what you mean when you say you have a "custom EUL named XX_EUL_US". The EUL table should be created in a schema named XX_EUL_US. This will then be the EUL owner. You will then need to connect to Discoverer Administrator as the EUL owner and grant privileges to Apps users and/or responsibilities.
The user should then be able to connect to Discoverer Plus/View using their apps username, responsibility and password.
To be able to connect directly from an apps menu you need to have the ICX parameters set correctly. The ICX: Discoverer Default End User Layer Schema Prefix should be set to XX_EUL (without the _US). The ICX: Discoverer End User Layer Language Override should be set to US or not set at all.

Report Layout difference in Discoverer Desktop and Discoverer Viewer

Hi,
A report was developed in Discoverer Desktop. It is having some 10 columns as data points. The summarized columns for those 10 columns are required. But only 3 columns should be displayed in Detailed Data Points. So we shrinked(brought together) all the unwanted columns keeping 3 datapoints displayed. Now it is working fine in the discovere Desktop. But when we open the same report in the Discoverer Viewer, all the 10 columns are displayed in the Detailed Data Points as well.
Thanks in Advance
Regards
Rakesh

hi Michael,
good morning..hope u had a good sleep.
as per your last thought y'day, even though i create a function for the sum of season values n select those columns into the report, those will not be shown as summarized columns on right hand side of the report. they will be shown as datapoints for every month in that selected season.
i think the only possible solution for like this report is to hide those unwanted columns. for this we have hidden checkbox option in tools->sort while developing. but this option is available only for tabular reports.
if u come up with any fresh solution for the fresh day...i am glad.
Thanks,
_Rakesh.
