Discoverer Desktop Issues 10.1.2

Hi,
I am using Discoverer Admin and Desktop both of Verions 10.1.2
I have no issue with Admin; I could do successfully all the work here.
In Desktop i have login successfully as Application user; and created simple Order Report workbook (Order_Report.DIS) and saved it.
Again when i login as application user in desktop; When i try to open my existing workbook (Order_Report.DIS); It will prompt me
Do you want to run the query for the sheet Ord_report; Yes/No; If i select option as Yes i am getting error mesg as Failed to connect to database; If i choose No I will get empty sheet; In either case I will see empty sheet appears; From the Tool Bar if i select Sheet --> Refersh Sheet; I am able to see records in my sheet.
When i continue working on this sheet; All of sudden i get error screen as Oracle Discoverer Desktop has encountered a problem and needs to close
Basically i have two problems in desktop
1. When I open workbook i get error as Failed to connect to database
2. All of sudden i get vague error as Oracle Discoverer Desktop has encountered a problem and needs to close
I would appreicate if some one can help on this.
Thanks!!

Hi,
I have the same issue with Discoverer Plus 10g Rel 1 (10.2.0.2 )
Desktop and Administrator are working good. So, I cannot resolve it by re-installation.
Also, this is not reproducible. Sometimes it works very smoothly, but sometimes it gives error for the same report.
Any idea ?
Thanks!

Discoverer Desktop Report issue

Hi,
One of my user is facing a format issue while running the report in Oracle Discoverer 10g. The report produces the following out put.
count(Col A)     Col B     Col C     Col D
12          A     200709     12-Sep-07
11          A     200709     21-Sep-07
24          B     200709     11-Sep-07
32          B     200709     13-Sep-07
10          B     200710     15-Oct-07
Col A is of number data type, Col B character, Col C is number and Col D is date
if Col D is removed from the report, the user is getting the result in following format
count(Col A)     Col B     Col C
23          A     401418
56          B     401418
10          B     200710
i.e. col C displays the sum of the value based in Col B instead of displaying it as 200709.
but when I ran the report from my end I'm getting the result in a proper manner.
count(Col A)     Col B     Col C
23          A     200709
56          B     200709
10          B     200710
Please help me in sorting out this issue.
Environment Details:
Oracle Discoverer Admin 10g(9.0.4)
Oracle Discoverer Desktop 10g (9.0.4)
End User Layer 5.0.2
Thanks in Advance.
Regards,
SS

@Himanshu3jul:
I'm not using any Oracle Application secure views. Also, the data that are being displayed is proper if Col D is not removed. If user removes Col D, the result is getting aggregated based on Col B but for me it is showing in a perfect manner.
@puppethead:
I'm afraid I may not be able to the check the registry on user machine since user is sitting at a different location.
@Rod West:
The default Aggregate property for Col C is set to <none> and it is grayed out. I'm not able to change it too. Also, if it is a bug then I should get the result as what user receives but I'm not facing any issues in that report but only user is.
Please let me know what can be done next to figure it out.
Also, I have the screen shots from my machine and from user’s. if you think that it will really help then I can post it. please let me know where and how I can post it so that you can have a look at it.
Thanks,
SS

Discoverer Desktop 10g : Issue with Chinese Characters

Hi ,
Discoverer Desktop 10g client is having issue in displaying Chinese data. My report has chinese characters in it and the same does not get displayed properly when run from Discoverer desktop. However, when I export the report in html format and opened it in browser, it is displaying the chinese characters properly. Browser was set to Unicode(UTF-8) character set.
I tried changing to different fonts in Discoverer Desktop, but couldn't get the chinese character issue resolved in Desktop.
Could someone , please tell me how to fix this issue ?
Please mail directly to [email protected]
Thanks
Venkatesh

I am facing the same issue too. I think it is a problem with the fonts. Get back to you later if I find any solutions.

Discoverer Desktop crash

When trying to open a report created by a colleague, Discoverer immediately throws a Windows (Vista 32Bit) error that "Oracle Discoverer Desktop has stopped working". I click close program, and Discoverer closes. It's a very simple report so I recreated it yesterday, ran it fine, could change parameters for different outputs, no problems. This morning I log in and when trying to open the newly created report from yesterday, same error. No exception, no memory pointers, nothing, just the Win error that it has stopped working.
Anyone seen this before? Running Discoverer Desktop v 10.1.2.3 Client v 10.1.2.55.26.

My colleague was able to open and modify the report that I created without issue so I suspect the report is alright, perhaps my installation? Odd that I can run many other reports just fine in the same environment and that this one ran fine from development, but as soon as I closed it to reopen, no luck.

Discoverer Desktop Graphing Questions

I have several questions about the graphing tool in Discoverer Desktop:
1. I'm bringing in a customer id field which I convert with a to_char in the query from a numeric field. Most of them are 5-digit, but some are 4. I notice in the x-axis the customer id's appear only for the 5 digit id's, and for the 4-digit ones the identifier appears. i.e. if the 5th record has an id of 1508, instead of displaying 1508 it displays 5. Does anyone know how to correct this?
2. In the y-axis values, is it possible to display more than 5 decimal places? (We're dealing with very small percentages). When I try to enter 6 or higher as the decimal value in Options, it says invalid number.
3. When I open an existing workbook, it readjusts the y-axis scale to a max of 1, when I've set it to .0001. How I can I make this retain my scale values?
4. Is it possible to display the y-values in the graph area itself next to the plot points?
Thanks for any help!!!!

Hi paul,
Its a good idea to upgrade from 4i to 10g 4i is no more used by many and their are some issues or bugs with it.The latest version is 11g which has been released 1 week back.If not go with 10g version available.
1) Do all reports have to be stored on the database to allow them to be accessed by Plus or Viewer? Can only the 10G client version open files from a local hardrive or shared network drive?Yes they have to stored in the database so any ened user can access them from plus or viewer.
Can only one report be open at any given time with Plus or Viewer? In client it is possible to have 2 reports open at the same time to facilitate easier comparisons.Yes,if the reports are registered as different reports and if the end user has access to both the reports thn he can open and compare it OR if both reports are in same workbook as different sheets than its easy to view or compare.
NULL values are still showing the word "NULL" even though in Tools Options we have set it to show blank, existing reports are still using the NULL value.It should show blank,might be some problem.In discoverer 10g i think you will not find this issues.
Hope this helps you.
Best Wishes,
kranthi.

USER UNABLE TO REFRESH DISCOVERER REPORT IN DISCOVERER DESKTOP 10g

Dear All,
HELP!!!
A new user is unable to refresh discoverer Reports in Desktop. All priviledges have been granted to username in Disco Admin and Usre is able to log into oracle Apps.
On the PC the user logged into someone else can log into Discoverer Desktop and run/refresh discoverer reports without any issues. Hence Ithink neither the PC nor the Discoverer installation is the problem.
Can anyone help? What setup/profile needs to be completed in order for the user to be able to run Disco reports.
Pls note that the following has been completed:
1. Business Areas Assigned to user and his responsibilities.
2. Desktop/Plus Privileges assigned.
3. Allow administration - DISABLED - NOT TICKED
Many thx
DI

Does this person just need to run reports? Or does this person also need to create reports? If the person just needs to run reports, try using Viewer for that person, rather than Desktop. This may be something that you need to log a service request with Oracle to get resolved. Pretty strange that can bring items into a new worksheet, but it won't run. Maybe there is an Oracle applications security issue (since logging in as another person does work)? You may be beating your brains out trying to find a Discoverer problem when it might be an application security problem. Though this is a wild guess on my part.

Discoverer Desktop (4)- Receiving error Attempt to Open Workbook Failed

Hi,
The reason for this error is multiple people are opening same workbook. This has never been a problem before as the user would receive message: "Open Workbook as Read Only..."
Now they only get the message: "Attempt to Open Workbook Failed."
We have tested here and have determined it is not a generell issue because we have the problem only on two workstations.
I check the registry HKEY_CURRENT_USER for diffenerence between the workstations but without any success.
There is no file access problem
Any idea?
Thx
Arnd

Hi all,
We are having exactly the same problem. I've come to the point that there's a problem between Discoverer Desktop 4i and XP SP3.
The scenario we have is:
a) If an user with SP2 creates a workbook and saves it into the network shared folder,
a.1) It can be opened by users with SP2 as many times as the want. They just receive the "Open Workbook as Read Only" warning message.
a.2) Users with SP3 can open it only if the workbook is not open by any other user. After that all users receive the "Attempt to Open..." error message.
a.3) If a user with SP3 makes any change to the workbook and saves it, it doesn't matter which SP version you have, the file becomes "corrupt" and only one user can open it at the same time.
b) If an user with SP3 creates a workbook and saves it into the network shared folder it can only be opened by one user at the same time
I've also made tests and the same error occurs if the .dis file is located in a local directory (c:\My Documents for example). I can not open it twice in my computer in two different discoverer desktop instances, and I have SP3, while another user with SP2 can.
Any ideas? Our Discoverer Desktop version is 4.1.48.06.00
Regards.

Showing Data in Oracle Discoverer Desktop

Dear ALL,
I am facing an issue in development of Relational reports in Oracle Discoverer Desktop.
Following are the details of my warehouse (Data Mart) database:
There are 2 Dimensions and 1 cube in the Data Mart. All the 2 dimensions and Cube are based on tables Currency, Accounts and Fact_Data respectively in our Data Mart.
Fact table contains 2 facts (CLOSING_BALANCE,MAX_BALANCE) and and the values are stored in USD currency.
The fact table contains 100,000 rows with all values/facts in USD currency.
Details of EUL(End User Layer):
I have derived all 2 dimensions and cube from OWB, which generates all the "Business Definitions" and "Business Areas".
Issue:
I need to show the end user a report (from discoverer) which shows all the values/facts in PKR currency.
What is the best way to get this report?
I have tried many methods, including "Creating a Materialized View (MV) on fact table which contains converted values in PKR and then making a view (Union of fact table and MV) which gives me 200,000 rows." But this solution has an issue that i can not join the View with other dimensions in Discoverer because View contains dimension keys (same as fact table) and dimension tables contain Surrogate Ids.
Thanks in advance for your help and suggestions.
Best Regards

Hi,
You cannot schedule and email using Discoverer scheduling. You have to use a third party scheduler and Discoverer Desktop. This article (http://ascbi.com/downloads/Third%20Party%20Documents/Scheduling%20through%20Concurrent%20Manager.pdf) may give you some ideas on how you can use third party scheduling with apps. A bit of extra development will also give you emailing of the scheduled output.

Hi,
Then you should be able to import your exchange rate table as a new folder in the EUL, join this folder to your fact table using date and create a calculation for the converted currency.

Discoverer desktop very slow

When I run some query in discoverer desktop, it take 2 minutes and more. When I take the query and run it on toad, the results appear in 93 ms.
I have tried to reduct th time take by desktop but nothing
Help me please.
Thank you

Hi,
You need to establish whether the problem is with the pc, the network or the database. So the first things you need to check are:
1. Is it a crosstab report, do you have the same issue if it is a table report?
2. How many rows does it return, do you have the same issue if you limit the rows to just a few?
3. Is it an Apps mode database mode EUL, if it is apps mode, you need to check the the users context in the database is not causing an issue?
4. Is this a general problem or a problem with a specific query?

Discoverer Desktop 11 and Oracle db 9i

Will Discoverer Desktop 11 run off Oracle db 9i?
I have copied tnsnames.ora file from 9i directory to 11, cannot connect (get ORA-12154)
Thank you in advance.

Hi,
I am not aware of any issues that would cause a TNS connection error. Check that the TNS details are correct for the new database using TNSping or SQLplus.

Discoverer Migration issue - Calculation item changes

Hi All,
In the development environment, I made some changes to the Calculation item in the existing Discoverer Workbook. It works in fine in DEV. But when I try to migrate (overwriting the existing workbook) it to ST environment (by opening it in Discoverer Desktop, and saving it to the Database) , it throws the below error
'Inconsistent or invalid data types used in arithmetic operation.'
Attempt to open workbook failed'
I have also tried by exporting/importing thru Admin, but while opening in the Desktop it again throws the same error.
When I am undo the changes(one by one) what I did to the calculation item, it is still throwing the same error, even when I come to a point that the formula for the calculation item is same as before.
But when I am trying to save back the last working copy of the workbook into ST environment, it works fine.
It looks like the environment issue/tool issue(Discoverer Desktop).
We are in Discoverer 10g. Please let me know if any of you faced this problem and any suggestions to overcome this issue.
Thanks,
Gowri.

Hi Gowri,
Have you compared the item format between DEV & ST? Are they the same?
Without seeing your actual calculation, I can only guess that you may try adding "TO_NUMBER" in front of the field that is causing issues.
That has helped me in the past.
Thanks,
Janet

Hi,
Do you have multiple oracle homes? If this is the case, you want to make sure that the tnsname.ora file associated with the oracle home associated with the Disco Admin tool is set-up properly.
Are you logging in as the EUL owner or as an APPS user (assuming you have an APPS implementation)? There are set-ups that need to performed before this will work (which are explained in the article below....e.g. the secure file).
Have you looked at the Knowledge Base article, "Questions And Guidance For Troubleshooting Common Discoverer Desktop and Administrator Connection Issues [ID 415614.1]"?

Discoverer Desktop and Administrator: which is the next step?

Hello everybody, i would like to ask you some help about understanding the following issue:
I noticed that Discoverer Desktop and administrator are being treated like obsolete.
Do they have a direct successor? I mean, is there any new product that has more or less the same functionality and the same philosophy?
I'm looking at the Business intelligence suite but it seems to be a bit much wide for my scope.
Thank you all in advance.

So, in a way you are saying that discoverer is still better than any other oracle products including discoverer plus. I mean, discoverer adm and desktop are useful for me since
they are standalone application and the understructure is quite light ( for example you don't need any application server behind like plus does but just an EUL).
And i'm agree with your parallel matching with sqlplus situation. I still prefer doing something with sqlplus since is more reliable and quick than sqldeveloper. But i cannot say that
discoverer desktop is the most reliable tool for reporting. In 6 months i used i found out many bugs and many strange behaviors that made me a bit crazy about this tool. I also tried discoverer plus but i found it extremely slow and unreliable. The level of productivity is something ugly, not just slow. So far indeed desktop seems to be the fastest and most reliable solution for a "quick" reporting development.
I would like to ask you another question: has the new hyperion platform some reporting tool like discoverer?
I mean if discoverer is the reporting tool for Relational OLAP what about the reporting for Multidimensional OLAP?
Thanks again.
Best regards

Limit Discoverer Desktop Instance Count and Run Time

Hi all,
I want to learn how I can restrict the number of Dicoverer desktop instances a user can open. I want to learn how to do it especially on Applications user basis because I will restrict only some of them. And also I want to know if it is possible to make a specific report to be able to be run only at given hours by given users.
To be more explaining here is my case; we have a report that takes too long to complete takes too much CPU and memory. We have shops that will start using Discoverer Desktop and the report in question. Now our users are not too careful to and open too many Discoverer instances, I want to restrict this to 1 for the shop users. Also, I want them to run that report only after 6:00 pm because it is when the center office which has 80% of the Oracle users is empty.
Is this possible, if it is could you tell me how to achieve it?
Thanks in advance.
