Opening multiple workbooks in 10g Plus

Hi there
Is there any way that multiple discoverer workbooks can be open at the same time in the same Discoverer 10g Plus session?
We have a separate workbook which is used to set session parameters for the view objects that our reports are based on. We can open this workbook, set the session parameters, then open and run the required workbooks after the first workbook is closed, but we will quite often get connection errors as a result - especially if we then need to reopen the first workbook and change some of the session parameters again.
There are no issues in the Desktop edition, where you can happily have more than a single workbook open at one time.
Has anyone encountered this issue, and managed to do anything about it?
Regards
CK

In the example given below, I have used 2 Discoverer Viewer reports.
Note:-Please change the necessary values to suit your environment like host name, port,username/password, database name, EUL name, Workbook names etc
The steps are listed below
1) Create a .htm file with the following piece of code and name it "1.htm"
<HTML>
<BODY ONLOAD="document.forms[0].submit();">
<FORM ACTION=host:port/discoverer/viewer METHOD=POST>
<input type=hidden name=username value=SCOTT>
<input type=hidden name=password value=TIGER>
<input type=hidden name=database value=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=<host_name>)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=db10g)))>
<input type=hidden name=eul value=SCOTT>
<input type=hidden name=connectionAccessType value=RELATIONAL>
<input type=hidden name=connectionLocale value=en_us>
<input type=hidden name=wb value=test_wb>
<input type=hidden name=ws value=test_ws>
</FORM>
</BODY>
</HTML>
2) If you are passing parameters, add the following to the code above in the .htm file, example
<input type=hidden name=qp_from value=01-JAN-1980>
<input type=hidden name=qp_to value=01-jan-1985>
<input type=hidden name=qp_from1 value=01-JAN-1970>
<input type=hidden name=qp_to1 value=01-JAN-2007>
So the code becomes
<HTML>
<BODY ONLOAD="document.forms[0].submit();">
<FORM ACTION=host:port/discoverer/viewer METHOD=POST>
<input type=hidden name=username value=SCOTT>
<input type=hidden name=password value=TIGER>
<input type=hidden name=database value=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=host)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=db10g)))>
<input type=hidden name=eul value=SCOTT>
<input type=hidden name=connectionAccessType value=RELATIONAL>
<input type=hidden name=connectionLocale value=en_us>
<input type=hidden name=wb value=Hello>
<input type=hidden name=ws value=Hi>
<input type=hidden name=qp_from value=01-JAN-1980>
<input type=hidden name=qp_to value=01-jan-1985>
<input type=hidden name=qp_from1 value=01-JAN-1970>
<input type=hidden name=qp_to1 value=01-JAN-2007>
</FORM>
</BODY>
</HTML>

Opening multiple sessions in SQL*Plus - Basic Question

Hi All,
I'm trying to issue an update on a table consists of 100 million rows.(update is done on every row). I have queries that updates this table in chunks of 20 million rows. So, if I open 5 sessions in SQL*Plus and run these 5 queries, does that mean Oracle opens up 5 processes in parallel for me ?
If yes, can I use parallel hint in each of these 5 queries and make the update even faster ? How does the above 2 differ ?
I'll be very glad if I hear from anyone,
Thanks,
Madhu.

For every client session there is a server session associated with it. Such as, when you open five session you will have five server session and it serve queires.
Regarding paralle queries, depends whether your table is defined as parallel, how many cpu do you have and also parallel parameters.

Error of access denied opening a workbook in discoverer viewer 10.1.2

When I open a workbook in discoverere viewer in the html page shows this message:
OracleBI Discoverer Viewer no ha encontrado los datos necesarios para mostrar los resultados de este evento. Corrija los errores y vuelva a intentarlo.
- access denied (java.lang.RuntimePermission oracle.discoverer.connections)
However data seems correct, but I don't know how to delete this message.
Thanks,
Carlos

Hi Carlos,
Metalink has some information regarding what sounds like a solution to your problem under Doc Id : 265228.1. Have a read and let us know if this is for you and whether you get it working in a development environment.
Symptoms
Discoverer 10g (9.0.4) Plus and Viewer throws 'page cannot be displayed'
Other symptoms
A.) Discoverer Plus shows a file download dialog with virus warning "Some files can harm your computer. If the file information below looks suspicious, or you do not fully trust the source,do not open or save the file."
Opening or cancelling will again throw "page cannot be displayed"
B.) Plus throws a blank page and Viewer throws 500 internal server error
Cause
Installation failure on configuring discoverer in OC4J_BI_Forms may caused the problem.
Using pre-production / beta code (M16b shiphome) will cause the problem.
Fix
1.) Edit the file $ORACLE_HOME(midtier)/j2ee/OC4J_BI_Forms/config/java2.policy
2.) Add the below lines at the end of the file
================================
grant codebase "file:${oracle.home}/discoverer/lib/discoverer5.jar" {
permission java.lang.RuntimePermission "oracle.discoverer.connections";
grant codebase "file:${oracle.home}/j2ee/home/-" {
permission java.lang.RuntimePermission "oracle.discoverer.connections";
grant codebase "file:${oracle.home}/portal/jlib/pdkjava.jar" {
permission java.lang.RuntimePermission "oracle.discoverer.connections";
grant codebase "file:${oracle.home}/portal/jlib/ptlshare.jar" {
permission java.lang.RuntimePermission "oracle.discoverer.connections";
===========================
3.) Restart OPMN.
4.) Invoke Discoverer Plus or Viewer.
Let us know how you get on.

Hi,
You need to run a trace for this user to diagnose this issue. Look at note 133055.1 for more details.

Firefox will not open multiple windows.

Just upgraded to Firefox 3.6.3. I can open multiple tabs in the open window, but I can not open another window. Possibly unrelated issue is the search bar not functioning.
As for the window issue, I've tried;
Ctrl + N
File [N]
File -> New Window
Rt Click Link -> Open in New Window
Nothing whatsoever happens with either of these attempts.
As for the Search bar I've tried to input a search and press [Enter] as well as clicking the magnifying glass with the mouse. As with the window issue nothing happens.
I'm not sure if these issues are related. Restarting does not fix these.
Addons are:
Adblock Plus v1.2
Add to Search Bar v2.0
All-in-One Sidebar v0.7.11
Bookmark This Page Plus v0.3.3
ChatZilla v0.9.86
Download Youtube Videos + v2.1.3
DownThemAll! v1.1.9
FEBE v6.3.3
Flashblock v1.5.13
Greasemonkey v0.8.20122408.6 (This looks very odd to me o.O)
Java Console v6.0.18
Java Quick Starter v1.0
Microsoft .NET Framework Assistant v1.2.1
Move Media Player v7
NoScript v1.9.9.77
Personas v1.5.3
ReloadEvery v3.6.3
Stealther v1.0.8
WebMail Notifier v2.4.1
== This happened ==
Every time Firefox opened
== Updating Firefox

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the ''Safe mode'' start window.
You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")

Opening multiple screens in safari

how do i open multiple screens using safari???

Cmd-N on the keyboard opens a new window.
Also, +File -> New Window+ from the menu bar does the same thing.
You can also open a new tab in an existing window (click the plus sign or Cmd-T). Then click-hold on the tab and drag it outside the current window. A new window will open from the tab.

XSLX as File Type in 10g Plus or 10g Desktop ?

Does anyone know if any patch is available to make xslx as file type in either Discoverer 10g PLUS or DESKTOP
Thanks

No. Discoverer generates Excel files with a .xls extension.
These cannot be changed to .xlsx in the export renderers.
You can export the report in .xls format and the same can be open with Excel 2007 (xslx) .
Thanks,
Sutirtha

How to open multiple report windows on button click without losing session?

Hi,
JDev : 11.1.1.2.0
I am trying to open multiple discoverer plus report windows using my ADF application.
My requirement is that user has to select multiple reports from the screen and by clicking on submit button all the reports should be opened in different windows.
1) Below link provided me the the first solution but I can't go with it because my page is jsff and in jsff it doesn't support form tag.
http://andrejusb.blogspot.com/2007/07/opening-report-window-in-adf-faces.html
2) RichGoButton also provide targetFrame property but there is not action property in it so I can't call backing bean method with RichGoButton
3) I have tried to open report windows using javascript window.open with ExtendedRenderKitService but on discoverer side it giving error message that Discoverer Plus cannot attach same session to multiple request.
4) I have created one jsp page in the same folder where my jsff is kept in my ADF application and on submit button click I have launch this jsp page using afConetxt.launchDialog and in jsp scriplet I have written response.sendRedirect to report url but here all report are getting open properly to seperate windwos but my ADF application session is getting timeout so after clicking on submit button it will automatically goes to login page it cann't stay with the current page.
Hoe you have understnad my problem and please provide me if you know any other solution aprart from above mentioned 4 solutions
Regards,
DevD

sURL is query parameter value that I want to pass on jsp page. It is used to set some value on jsp page.
If this is not a right approach then let me know how to pass the parameter in jsp page.

Does Discoverer 10g Plus allow uploading of reports from local drives?

Hi ,
Does Discoverer 10g Plus allow uploading of reports from local drives? Or like 4i is this only possible from Desktop Client?
Regards
Ram

No, you can't bring in Disco workbooks from a local drive with 10g Plus.
Only from the database and/or scheduled workbooks.

Oracle Discoverer unable to open the workbook due to insufficient Permissio

I have an error message when I try to open a workbook with some worksheet.
( It's working fine with only one Worksheet)
Any idea ?

Well here's how it's supposed to work.
Step 1: Create workbook A with 5 reports (5 worksheets)
Step 2: Go into Disco Admin and make sure each business area where the folder(s) referred to in the step 1 can be seen by each user you're sharing the workbook with (security). For example, if worksheet 1 accesses business area: GL_Stuff, then security on GL_Stuff must be with all 5 users you'll share the report with.
Step 3. Share workbook A with the 5 users (via Plus or Desktop where you created the workbook).
Step 4. All users can see and run the workbook / worksheet.
Questions:
1. I don't know what you mean in your Step 3. There's no permissions at this point. What you do is give read to ALL tables / views, etc. to the owner of the EUL. Then either the owner of the EUL (or another user who has been given admin privs) controls security to other roles via the Tools-> Security window in Admin.
2. Are you 5 worksheets based on the same business area or are they going to different business areas. No problem if going to different ones, but you must make sure security for sharing with the other users / roles is for each business area they will be using to retrieve data from the folder and therefore the underlying view / table / sql statement.

How open multiple responsibilities in the same user login session in R12 ?

Dear All,
Can anyone help me to know how to open multiple responsibility in the same user login session in R12 ?
Thanks..
Edited by: G-oracle on Sep 18, 2011 11:22 AM

Can anyone help me to know how to open multiple responsibility in the same user login session in R12 ?What do you mean by open multiple responsibilities in the same session? You can only see the menu of one responsibility at a time, so how to do you expect the application to let you see multiple responsibilities/menus in one session?
You could open another session and this way you can access more than one responsibility at the same time.
Thanks,
Hussein

Is there a way to open multiple windows in firefox 5.0? I can't do it from windows quicklaunch and the right click"open in new window" does nothing.

Yeah, not much more to say. Since I upgraded to firefox 5.0, I can no longer open multiple windows. Multiple tabs work, but I don't like tabs. Please help.

Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.
