Thank you for your help.

Hi Kayaman,
Thank you for your answer,
the option was already selected.
Also, in the Java plug-in options, Iexplorer is already chosen.
The applet runs fine with Netscape7, but there is a problem with
Iexplorer6. I have downloaded all the updates for iexplorer6,
so I have the latest versioin with all the fixes on it.
In addition I opened the java console to see the messages,

Problems with Discoverer Viewer and the printable page

Hi,
I have a problem in Discoverer Viewer. I run a workbook, see the results and I click on "Printable Page". I set the page setup options to "Portait" and "100% scale". I preview the workbook in a PDF file and it's ok, I see the results in "Portait" and "100%".
I close the PDF file and I click again on the "Printable Page". This time, I set the workbook to "Landscape" and "20% scale". I preview the workbook in a PDF file and it's NOT ok, the results are still in "Portait" and "100%". And the date/time in the workbook is the time when I run the workbook the first time. So, it's seems like a browser cache problem. The problem repeats until I clear the brower cache. At that moment, the workbook will take the page setup that I set at this time. However, it will be the same workbook with the same results until I clear the cache once again.
If I save the PDF file on my Windows Desktop and I overwrite it each time, it's ok.
Can somebody help me on this??
Thank you!
Mathieu

Hi Michael,
I'm clearing the browser cache by going in Tools -> Internet Options. In the "General" tab, I click on the "Delete files..." in the "Temporary Internet Files" section" (middle of the window).
But I don't indicate that Discoverer is saving my printable page changes. I say that the first time I run a workbook, Discoverer saves it (the results) in the "Temporary Internet Files" folder in a PDF file. Each time I run the same workbook after that, Discoverer don't overwrite the file in the "Temporary Internet Files" folder. He takes the PDF file that is already there and show it to me. So, the results are the same even if the data has changed. It does this until I clear the browser cache (it deletes the PDF file in the "Temporary Internet Files" folder).
Do you understand?
Regards,
Mathieu

Timeouts for Discoverer Viewer and SSO

We've enabled SSO for Discoverer Viewer 9.0.4. We set the Viewer timeout in the web.xml file to 120 minutes. We set the SSO Global user Inactivity Timeout to 240 minutes. Viewer sessions don't timeout at 120 minutes. Does the GUIT timeout override the Viewer timeout?
--- Steve

Hi
As far as I know, the Viewer sessions don't time out using the Discoverer settings. These only affect Discoverer Plus. The SSO timeouts will apply though. Out of interest can you tell in which folder was the web.xml you modified?
By the way, 240 sounds an awful long time to allow an SSO connection to stay active.
Best wishes

AS 10g 904 Discoverer Viewer and remote db EUL

I have installed Oracle AS 10g (9.0.4) with Discoverer Viewer on a RH AS3 box. I need an EUL setup on remote db (9.2.0.5). Do I have to have Discoverer Windows Admin tool or should I be able to setup an EUL from scratch with the java command line? I am getting core dumps trying to do create_eul using the java command line method. The log file is complaining about no default eul or specified schema tables available. Any help much appreciated.

Add the host name to your etc/hosts file. If you are on windows it would be under c:\WINDOWS\system32\drivers\etc\hosts. Try adding that entry to ur hosts file along with the actual ip address. That should make it work.
Thanks,

Discoverer Viewer and Scheduled workbooks error

Hi
Hope someone can help.
I am scheduling workbooks in Discoverer Plus 10.1.2.48 with the intention of viewing them in viewer.
The report shows itself as running okay in Admin, but when I open the report in Viewer or Plus I get errors including:
ORA-03106 Fatal two task communication error
or
"unable to generate sql for this scheduled workbook"
I suspect they might be retrieving fairly large result sets (10 K rows +)
Please can anyone offer advice on how to resolve this?
Many thanks

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.
Best wishes
Michael

Discovere viewer and scheduled workbook

I scheduled a workbook to run nightly. If I open the report, that belongs the scheduled workbook, in Dis Viewer, why Discoverer re-run the query again??? This defeated the purpose of scheduled workbook.....

Yes. That is what I understanded. But when in a SQLPlus session I captured SQL statements of both unscheduled and scheduled reports and they both run the same SQL statement

Discoverer Viewer and Reports

I have some questions about ORA 10g Discov Plus and Reports.
1. Is it possible to define page items as parameters and use them for an dynamic link? Could it be that the dynamic link parameters are limited to parameters based on columns or rows?
2. If i define every level of an hierarchy as parameter and use them in an dynamic link, how can i avoid the following situation:
Report X contain a hierarchy like Region->Country->Town
I have a dynamic link containing these hierarchies as parameters.
If i use the link at region level and did not drill down to country or town then the parameters country and town are filled with the line name and i get no data. If i refresh and delete the line name for these parameters the records appear in the worksheet. How can i get these parameters to be empty, if i don't drill to them.
3. Reports doesn't recognize the links as it should. If i do not change the report, the links work ok. It opens the second worksheet with the data. If i change a page item or drill to another hierarchy level i get an fatal error (no special code, only fatal error occured, please contact your admin). If i drill down and up again i get the error to. The link only work if i doesn't changed anything.
Anybody got some ideas about these questions?

Hi Rod,
I got it, and had captured the LOGIN_USER.
Now the problem is:
I am using a table SECURITY_ACCESS_MV_D to apply security to a user.
I am using the below query in customer folder as:
select a.emp_id,a.empname,a.salary,a.mgr_id
from emp
where salary is not null
and (emp_id,mgr_id) in ( select distinct emp_id,mgr_id from SECURITY_ACCESS_MV_D where login_user ='HIM'
I am using IN because I have many other column in SECURITY_ACCESS_MV_D, not used in above query which will create Cartesian join if I exclude them in the main query, if I use the simple join in the query.
Now problem is how can I use the LOGIN_USER item (it will come when the certain user will login) in place of 'HIM' ( hard coded value). I want this filter (as mandatory) in the Discoverer Administrator EUL so that it is independent to the user reports.
I can’t find using type of parameters there as in reports we do.
Hope you got it.
Once again this article will greatly help everybody in security while implementing the OD solution.
Thanks,
Himanshu Tiwari

Discoverer Viewer Report with Page Items Slow Performance

I created a report in Discoverer User that has page items and parameters and runs fine (under 3 minutes) in Discoverer User, but when I try and run it in Discoverer Viewer it takes a long time. It took over 70 minutes before manually terminating it. I made a copy of the report and removed the page items and tried to run it again in Discoverer Viewer and now the report runs in under 3 minutes. Any idea why a report with page items would run in Discoverer user fine, but not discoverer viewer?
I am using Oracle Business Intelligence Plus 10g (10.1.2.55.26)

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

Hi all,
we recently installed the patch for web services in discoverer.
But since then we've been getting a strange exception. Have you seen this before, or know what it is? The exception is resolved after a restart of the server. I'm getting it when I try to view http://host:port/discoverer/viewer for example.

HTTP 500 - Internal Server Error from Discoverer Viewer to Portal

HI,
I created a tab with a list of workbooks created with Discoverer Viewer and published with Discoverer Portliest Provider (List of Database Workbooks). Another tab contains four Discoverer Worksheets created with the same account. Everything works well but if i click on a report in list and open Discoverer Viewer, when i return to portal and go to tab containing worksheets i see message "HTTP 500 - Internal Server Error" and i'm not able to do anything. I only can close my browser and i must reconnect to portal!
Can you help me?
My portal version is cg (9.0.4), i'm using Windows 2000 ESP and Internet Explorer 6.
I tried with Olin and Mazola but result did not change.
I used a public connection bud i tried a private connection too. Nothing happened.

The application.log file, under the OC4J which running your Discoverer provider, should give you some hints about the problem you're facing.

Online response time in discoverer viewer?

Dear sir,
Can anyone help me,
In discoverer view and plus,how to maximise the response time for the viewer,while n-number of visitors requesting the same report.
How to analyse that? what settings are there?
Plz help me , its urgent for my project?
Regards
chandrakumar

In case this helps anyone else - this is the reply I got when I asked SAP this question:
the total user response time is response time + frontend network time.
GUI time is already included in the response time (it is the roll in andwait time from the application server's point of view).
The 'FE (Frontend) net time' is the time consumed in the network for thefirst transfer of data from the frontend to the application server andthe last transfer of data from the application server to the frontend
(during one dialog step).

Strane Issue with Discoverer Viewer

Hi All
I Created a report in doscoverer plus (OracleBI Discoverer 10g (10.1.2.2)). I have a page item LOCATION and in the drop down box i have four locations LOCATION 1,LOCATION 2,LOCATION 3,LOCATION 4. In discoverer plus the page items are working just fine, whenever i select a location from the page item it gives me the report based on my selection. The problem is when i look at the report in Discoverer Viewer and try to select a different location (other than the default which is LOCATION 1), for some reason it doessn't select a different location but just shows the default. Once i logout and log back in into the viewer it works fine again. Can anyone please tell me whats causing this?
Thanks

What browser are you using and have you tried a different browser?

Discoverer Viewer Configuration File

Hi,
There is a scenario where in, most of the users use Discoverer viewer reports from the same login ID, They do changes and save the Workbook. Now when a new user logins he see the changes saved by the previous user . Now we dont want to allow the users to save changes and want to change the config setting so that no user can do any changes.
As per my unerstanding, one way of doing so it by login to application server and Uncheck the preference check box and save the changes. Doing this the preference tab will not be visible to any user.
Want to know is there any other way by which preference tab can be Disabled but still can be seen on the right corner of the viewer page?
Or is there a way we can change the configuration setting in any of the config file of discoverer viewer so that users are not able to change the setting...
Discoverer version is 10g.
Thank You.
Regards,
Anuj Malhotra

Hi Michael,
The Scenario is like, most of the users use Viewer only to access reports.
The main aim right now is to some how not allow users to change the settings whcih they change using the preference tab or presentation options.
I checked it the config document of Discoverer viewer and found:
The Steps to remove Preference tab or presentation options in Oracle Application Server Discoverer Configuration Guide
10g (9.0.4) are as follows:
1. Open the ui_config.xml file in a text editor or XML editor
2. Locate the <appearance> tag in the file
change the value of the display_preferences_link tag to false
change the value of the display_presentation_options_link tag to false
3. Save the ui_config.file
But I didnt not find the steps to remove the preference tab or presentation option using Configuration.xml file in Oracle® Business Intelligence Discoverer Configuration Guide 10g Release 2 (10.1.2.1 ).
It was mentioned that to remove the presentation option in 10g version we need to login to Oracle Application server and uncheck the preference tab Option.
Want to know is that the only way of removing presentation options or preference tab from 10g Version or something can be done from configuration.xml file also.
Regards,
Anuj Malhotra.
