Minimizing Discoverer Plus causes it to lock up

We have a user who complains that when he minimizes Discoverer Plus for a long period of time and then tried to maximize it, it locks up and he has to do a ctl-alt_del. Has anyone ever encountered this before?

Hi puppethead
That sounds feasible to me. I'll try it on my own machine and post the results shortly.
Best wishes

I completed my test and it was inconclusive as Discoverer did not lock up. I correctly got the message saying that Discoverer was about to time out, although I ignored it as if I wasn't there. About a minute later I got the message that Discoverer had timed out and that message remained in the browser window no matter how long I ignored it. As soon as I clicked on the minimized browser Discoverer told me it had timed out and asked me to click the OK button.
Therefore, I'm not convinced that the timeout is the cause of Discoverer locking up. At least not for 10.1.2.2 anyhow which is what I'm using.

Discoverer Plus returning no data and IDL:DCCORBAException:1.0. Desktop OK

We are attempting to create a worksheet in Discoverer Plus. It is based on two tables joined with an outer join. We select 1 field from the master table, then 6 fields from the detail table. The query runs OK (we have no conditions, sorts, calculations nor totals).
When we attempt to add a 7th field from the detail table and run the query, Discoverer Plus displays the error message 'IDL:DCCORBAException:1.0' and the results region says 'No Data'.
If we build exactly the same worksheet with Discoverer Desktop against the same EUL, the query runs OK and returns the expected data. I've experienced this problem before and solved it by deleting the detail folder and re-creating it. (We are using custom folders). After this the query ran OK in Discoverer Plus and returned the expected data.
Has anyone else come across this? Do you know what causes it and/or any better method of solving it?

I'm wondering if this has anything to do with the default position (and default aggregate) for the EUL folder item? I can see that some of the folders have number type items with default position 'Data Point' and others have these with default position of 'Top or Side'. I'm totally stabbing around in the dark here; looking at EUL folders which exhibit the problem and those which don't.
I've tried changing one field to 'Data Point' and it hasn't helped. Will try changing the join items now I think.
If anyone has any comments, would be v. grateful as I'm looking at dropping folders which have quite a bit of code around them and trying to re-create them exactly, which is a risky and horrible solution.

Discoverer plus report does not sum up the column

Hi All,
I am running the discoverer report from discoverer plus (web version) and was
trying to use the sum function to sum the total amount of the report.
The sum function does not work and it only display Cell
Sum: (blank) with no actual data.
When i checked the report details some columns are calculated based on the columns which i want to sum up.
My query uses CASE function to calculate one of the columns.
I changed the aggregation behavior setting to "Show the sum of the calculated values from the contributing cells "
then also i'm not able see the totals.
Any ideas please share with me.
Thanks in advance,

Hard to answer your question without seeing what you are trying to do. Issues like this are often better reported to Oracle support, where they can get a web sesison going and be able to see what you see on your computer. Would be helpful to illustrate exactly what your detail looks like and how you are trying to create your sum. There could be several possible issues that could cause your problem, so all I can do is speculate some. Are you trying to sum one column, or are you creating multiple totals (for multiple columns)? Do you have any rows in the column with a NULL value? NULL values will be a problem when trying to sum up a column. You would need to convert the NUll value to something else, probably a zero. That would be the first thing I would look at. Hope that helps a little bit.

Can't Create Saved Connection in 11g (Discoverer Plus).

We're getting ready to go live with a new installation of Discoverer Weblogic 11g, but we have run into a problem. We are getting errors when we have any user try to create a saved login connection from their login screen. We hit "Create Connection" and enter all the required login info (as we always did with our 10g version), but when we hit 'Apply' or 'Apply and Connect' we get the following errors.......
A connection error.
- Oracle BI Discoverer Viewer cannot save the connection. Check for other errors.
- ORA-04063: package body "PROD_DISCOVERER_PS.WWSSO_API_PRIVATE" has errors ORA-06508: PL/SQL: could not find program unit being called: "PROD_DISCOVERER_PS.WWSSO_API_PRIVATE" ORA-06512: at line 1
Users can login just fine when they enter all their info on the login screen, this is only happening when we try to create the saved connection. Is anyone else running into this on 11g? Is there a setting we are missing or something? Maybe something in the pref.txt file? Any help would be appreciated, especially since we are being asked to go live soon. Thanks!
Here is our system setup:
Oracle BI Discoverer 11g (11.1.1.4.0)
Oracle Business Intelligence Discoverer Plus 11g (11.1.1.4.0)
Discoverer Model - 11.1.1.4.0
Discoverer Server - 11.1.1.4.0
End User Layer - 5.1.1.0.0.0
End User Layer Library - 11.1.1.4.0
Oracle Database 11g Release 11.2.0.1.0 - 64bit Production

JVM Memory Available:     9046KB out of 37372KB
Operating System:     x86 Windows XP 5.1
Using protocol: RMI protocol over JRMP transport

Additional info:
Based on the error messages, we can see something is wrong with the package being called. We had a long running help ticket with Oracle opened, but in our opinion, it was not really resolved. We provided the following info after a request from Oracle....
The package does exist. The package is valid but the package body is invalid due to missing dependant objects
It is owned by PROD_DISCOVERER_PS.
The database version is 11.2.0.1.0 (64 bit)

We have tried to recomplie the package, still invalid.
After some further questions we were asked to provide info on the app_registry.......We got an error when trying that.......
The app_registry object does not exist ...
SQL> connect sys as sysdba
Enter password:
Connected.
SQL> select comp_id,version,status from app_registry;
ERROR at line 1:
ORA-00942: table or view does not exist
In the end (after a lot of back and forth), Oracle could not reproduce our problem on their test system. Because their test system uses Enterprise Edition and we installed Standard Edition, their solution was that the issue is caused because we are using Standard Oracle DB and we should be using Enterprise Edition. Creating a saved connection doesn't sound at all like something that would be affected by Standard or Enterprise edition. That's not an easy "solution" for us right now, and we can use a real fix. That's like taking your car into the shop because your blinkers don't work on your 2010 model car and the dealer's solution is "Oh, your 2010 car blinkers don't work? We have a 2011 model and they work just fine. You'll need to buy a 2011 car so the turn signals function."

Discoverer Plus

Hi I'm using Discoverer Plus, When I change a field in an existing report from being a some to detail, I get the following error message:- Contact with the discoverer server has been lost. to continue your work, please restart Discoverer Plus. If this problem persists contact your server administrator.
I then try to save the report and repeatedly get the same message not allowing me to save the report.
I have done a database session trace and I can see there are some parsing errors, although not sure what this really means.
Can anyone help or has anyone had this error before. Bit concerned as this is happening only on one report and only for the admin user.
Please help... deperado...

Hello
Another possibility is that changing to a Detail may now be causing a fan trap or replication of values which in turn are causing bad results.
I'd take the query back to the basics and knock things out then add the Detail to get a working report. At this point I would start adding items back in and see where the problem lies.
If you suspect that a fan trap may be the cause try temporarilly changing the properties of the join to be 1:1 instead of 1 to many.

Menu "Export" in Oracle Discoverer Plus 10g

Hi..
Is there anyone knows how to hide "Export" menu in OracleBI Discoverer Plus 10g ?
Any help will be appreciated.
Regards,
Handoko

I have a T420 Lenovo with dual video card configuration is causing the Discoverer Plus 10g views to not refresh correctly.
I was able to find a solution to this issue. It requires the following changes in the system BIOS.
• In BIOS under Config -> Display ->Change the Graphics Devices to Discrete
• In BIOS under Config -> Display ->OS Detection for NVIDIA Optimus -> Changed to Disabled
Now system will only use the Nvidia Card versus the dual card configuration (Nvidia + Intel HD Graphics)
Discoverer Plus works correctly.
Hope this helps.

Error while connecting to discoverer plus OLAP

when I try to connect to discoverer plus OLAP I get this error
ERROR:An error occured during OLAP API metadata retrieval,this probably caused by inconsistent metadata
have you idea how to resolve that problem?
Thank you

Hello
Do you have a copy of my Discoverer 10g Handbook? If so, chapter 16 on pages 548 to 612 cover OLAP in some detail. This chapter was written by Mark Rittman, OLAP expert extraordinaire.
He also runs a blog which you may find to be of some help: http://www.rittmanmead.com/blog/
There is at least one Oracle by Example which may help: http://www.oracle.com/technology/obe/obe_bi/discoverer/discoverer_1012/index.html
There are also some Oracle demonstrations on OLAP on the bottom right hand side of this page: http://www.oracle.com/technology/products/discoverer/index.html

Discoverer Plus 10g Title & Table Viewing Size

Is there a way to increase the screen resolution of the title and table area in Discoverer Plus 10g? The font size says 10pt, but on the screen it looks more like 4pt. I couldn't find any settings in Plus to change it. Thanks, Amy.

Cause
By default in Discoverer Plus 10.1.2 fonts are rendered smaller in Java
than in other Windows applications.
Already saved workbooks will not have any change in font and formats even if
your default fonts are changed unless these workbooks are explicitly opened and
modified for using new fonts. The cause for this behavior is that when
workbooks are saved, font information is also along with it. This is very lengthy approach if you have over 1,000 upgraded workbooks.
Solution
To implement the solution, for existing/upgraded workbooks please execute the following steps:
Set AdjustPlusFontSize = "True" in pref.txt file.
This setting will make Discoverer Plus to display the font size correctly. It specifies whether Discoverer Plus Relational adjusts the font size to correct a discrepancy in the Java virtual machine, resulting in a smaller font size than other Windows applications.
true = adjust font sizes
false = do not adjust font sizes
1.Navigate to <Discoverer Home>/discoverer/util directory.
2.Edit pref.txt file and modify the setting as
AdjustPlusFontSize = "true"
under [Application] section
3.Run the script applypreferences.sh

I've been working with this annoying problem for a week, and Oracle support team had spinning around the trouble without a valuable working idea.
Certainly, you've solved this situation - I hope so!
Please, can I count on you for any suggestion that can solve my problem?
Thanks in advance for any reply

Discoverer Plus -- Cannot Load Java Applet after JRE upgrade to 6

Hi,
After our users upgrade Java Runtime Environment to version 6 Update 1, Discoverer Plus stops working, the applet is opened but does not load.
Uninstalling the update solves the problem.
I disabled the automatic upgrade of Sun JRE on a few machines, but we have over 100 users.
Did anyone else face the same issue and is there any patch for the Discoverer installation?
Thanks,
Vlad

Hi George
You can get the 10.1.2.2 patch (4960210) on MetaLink. Be warned though that this not a small patch. It is 1.6 GB in size and is a full upgrade of the 10.1.2.0.2 application server.
I had some interesting problems when I first starting patching up to 10.1.2.2. First of all, if you are using a Windows server, you need to make sure that there are no lowercase characters used in your computer name. I know this sounds crazy but 10.1.2.2 will fail on Windows if you have this. If you've already got lowercase names in your machine you can't simply change the machine name to upper case because your existing application server will stop working as it embeds the machine name into dozens of configuration and setup locations. None of the Microsoft applications care what you call the machine as they don't embed like this but Oracle does. You'll probably end up having to reinstall the application server. However, the good news is that this only affects Windows and only when you have lowercase characters in your machine name.
Secondly, also on Windows, make sure there are no spaces anywhere within any of the folder names from where you will be installing the patch. This is another cause of failure. Thus, don't put the patch on your Desktop as there are spaces in Documents and Settings!
Thirdly, and this can happen on all platforms, if you are using an Infrastructure database and it is at 10.1.0.4 or less you will need to upgrade that database to 10.1.0.5 before you start any of the application server upgrades. If you don't do this your upgrade will fail. The release notes for the patch clearly state this but because they are very large I missed this the first time round and - oops - failed upgrade.
By the way, it seems Oracle have also released a patch (5758865) , available on MetaLink, with the fix for IE7. This is a one-off patch and requires a password which means you will have to raise a service request and tell Oracle you are having trouble drilling in Viewer when using IE7. This patch is applicable whether you are using relational or OLAP modeling. It can only be installed on top of 10.1.2.2.
Best wishes

Discoverer Plus connections lost..!!

Hi,
We always get emails from users saying that the Discoverer Plus Connections saved on the local machine are lost. They have to recreate the connections again.
What could be the cause of the issue?
I told them not to delete cookies as the connections are stored in IE cookies, but is there any solution for this?
Thanks!
Yogini

Yogini,
10.1.2.48.18 is the basic version of 10g Rel 2 BI. You can see that connectivity issue will be overcomed by this but this version is not stable. Specially if your envrionment is of Oracle E-Business Suite.You can face some more weird issues like icons of toolbar getting disabled etc.
Oracle recommends to go with 10.1.2.54.25 and it is very much stable.only way to reach this version by patch 4960210.There is one more patch over 10.1.2.54.25 for some Discoverer viewer issues.
Moreover the patch is available for both Developer tools and also BI middle tier.
Have Fun..

Discoverer Plus Scheduling Problem

Here is my Configuration:
OracleBI Discoverer 10g (10.1.2.3)
Oracle Business Intelligence Discoverer Plus 10g (10.1.2.55.26)
Discoverer Model - 10.1.2.55.26
Discoverer Server - 10.1.2.55.26
End User Layer - 5.1.1.0.0.0
End User Layer Library - 10.1.2.55.26
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi
Copyright © 1999, 2005, Oracle. All rights reserved.
First of all, Disco scheduling in Plus works fine in our production instance. In our test instance, I have a user whom wants to schedule workbooks from time to time where a new folder is being tested. My problem is that when I am on step two of the schedule wizard and I select immediate (or manually place a time in that is very soon (e.g. 5 minutes from now)), the workbook took hours yesterday to show as “scheduled” in the “Managed Scheduled Workbooks” tool.
Today it works fine and runs immediately. I created a very simple workbook titled, "scheduling test", which has one column, a calculation which is set to sysdate. I began testing this yesterday.
Does any thoughts on what is causing this trouble?
I did the following:
1. I notice that a package is created in the scheduling schema for the workbook scheduled.
2. I tried to query for scheduled jobs created by dbms_job (queried Dba_Jobs using the system account and could not find the job...either yesterday or today).
3. I tried to query v$sql with the intent of seeing when the package, batch_rep_secure.submit_job,is executed...but could not find the scheduled records.
4. I tried gleaning information from the "Manage Scheduled Workbooks" tool associated with the Disco Administrator, and the time column was null (yesterday).
5. I had our dba check the init<sid>.ora file and confirmed that the job_queue_processes have been set to 10.
To rectify this yesterday, I just manually executed the package, EUL5_BATCH_PACKAGE10061409140713, and shortly thereafter, the scheduled workbook would have a new table associated with it which was consumable through Disco Plus.
My hunch is that our job queue was backed-up significantly yesterday and this was delaying the scheduling and running of scheduled workbooks.
Does any one have any thoughts about what the root cause was here and how I could confirm this?
Thanks,
Patrick

Hi Patrick
That would be my hunch too. You could also check the database privileges granted tp each user. Here's what I use:
accept username prompt'Enter Username: '
accept pword prompt'Enter Password: '
create user &username identified by &password;
grant connect, resource to &&username;
grant analyze any to &&username;
grant create procedure, create sequence to &&username;
grant create session, create table, create view to &&username;
grant execute any procedure to &&username;
grant global query rewrite to &&username;
grant select any table, unlimited tablespace to &&username;
grant execute on sys.dbms_job to &&username;
grant select on sys.v_$parameter to &&username;

Discoverer report - Output from Discoverer plus is not the same as Discoverer desktop

As a part of Upgrade project we are migrating the discoverer reports from 11i (11.5.10.2) to R12 (12.1.3) .After migrating to R12, for a custom discoverer report the output given by discoverer desktop is correct (24 rows for a scenario). But the report output from Discoverer plus does not show the credit transactions (2 rows). The output from Discoverer plus shows only 22 rows (24 - 2), which is incorrect. The query is the same in Discoverer desktop and Discoverer plus.
Please let me know why these transactions that are appearing when the report is run from discoverer desktop are not appearing in discoverer plus. Is there any setup in discoverer plus for this?
Regards,
Brajesh

Pretty hard to answer a question like this. Best bet would be to copy the existing discoverer plus book and start removing conditions, fields, etc until those two rows from desktop show up and see if you can work it out.
