DISCOVERER Plus connectivity issus

Encountering a connection issue when using DISCOVERER Plus. When attempting to refresh (using the refresh icon) after five-ten minutes of being idle, the message "Failed to connect to database" is received. Users then have to reconnect to DISCOVERER via the connection screen. I don't have any knowledge about disvocer. The platform is windows.
Your help will be appreciated. Thanks.

Hi,
The first think you will want to check is the timout preference for Discoverer Plus.
It is located in <oracle_home/discoverer/util/pref.txt
Once you change it, you will need to run applpreferences.sh or applypfreferences.bat (for Windows) and the next sessions will pick up the change.
Discoverer Viewer timeout is in the web.xml file.. see the Discoverer Configuration Guide on OTN
http://www.oracle.com/technology/documentation/discoverer.html
Hope that helps.

Steve

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,
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 connecting error

Dear All,

any help will be appreciated.

Hi Christian
In your connection to the database are you using a DNS named server or are you using an actual IP address?
By this I mean, when you launch Discoverer, do you do it this way:
http://servername.domain.com:7777/discoverer/plus
or this way:
http://ipaddress:7777/discoverer/plus
If you are using the former, can you go to the server itself and run Discoverer ok? If you can then it is a case that your local machine cannot work out what the IP address is. Let's say, for arguements sake, that you server is http://myserver.mydomain.com and that the IP is 192.168.1.100
You could try editing your HOSTS file and inserting a line in there to associate the IP with the domain. To do this, follow this workflow:
1. Right click on Windows Start button and from pop upmenu select Explore
2. Navigate to the folder called Windows/system32/drivers/etc
3. Locate the file called HOSTS
4. Edit this file with Notepad
5. Insert a line like this:
myserver.mydomain.com 192.168.1.100
6 Save the HOSTS file and exit Explorer
This associates the IP with the server name.
Does this help

Discoverer Plus connection error

Hi all,
I installed the Oracle Business Intelligence and its Tools and I created BI_ADMIN for EUL in Discoverer Administrator. But I get the following error when I connect to Discoverer Plus:
The application encountered an invalid state.
- - Nested exception: org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 201 completed: No
OracleBI Discoverer Viewer was unable to find the necessary data for displaying the results of this event. Please correct any errors and try again.
Please guide me for solving this error.
Thanks

Hi
To follow up on the link posted by CD, summarized here:
"The Discoverer network connection configuration uses a DHCP server to get its IP address. In the insallation instructions for the Application Server it suggests using a Microsoft Loopback Adapter and add a line in the HOSTS file to map the host name with the loopback IP.
This procedure appears to work fine with Discoverer 9.0.4, but doesn't always work with Discoverer 10.1.2
The workaround then is to try assigning a static IP to the server and uninstall the loopback adapter. With a static IP most of these connection errors should go away."
I would also add that you have to make sure that a fully qualified domain name is used on the server. If you have already installed Discoverer without a fully qualified domain name you will probably have to wipe the installation and start again.

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
Java Virtual Machine:     Sun Microsystems Inc. 1.6.0_29
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)
SQL> select OWNER, OBJECT_TYPE
+2 from all_objects+
+3 where object_name = 'WWSSO_API_PRIVATE';+
OWNER OBJECT_TYPE
PROD_DISCOVERER_PS PACKAGE
PROD_DISCOVERER_PS PACKAGE BODY
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."

How to hide discoverer connection page after opening discoverer plus?

Hi,
I invoke the following url in browser window 1 to open Oracle DIscoverer Plus.
I notice the browser window 1 will open a window (say i call it browser window 2) to display the Oracle Discoverer Plus application.
Once the Oracle Discoverer Plus java applet is fully loaded, the browser window 1 will show the Connect to Discoverer Plus page.
I wonder if we can configure not to show this page as my users might confuse to see a few existing connections listed there and in fact if possible, I don't want user to see the list of connections.
Anyway to get rid of the page?
Please advise.
Thank you.

I am trying to use URL parameters to keep Discoverer Plus from launching a new window after login. I notice that what works in Discoverer Viewer does not work in Discoverer Plus.
The following works with Discoverer Viewer :
<iframe src="https://cohort50.spinsys.com:8251/discoverer/viewer?framedisplaystyle=embedded"
width="100%" height=100%></iframe>
After Viewer login the next page displays in the same window, just as I want it to.
Discoverer Plus behaves differently. If I try this with Discoverer Plus a new window is launched after successful login. I also tried adding the pluspopup=false parameter to the URL, but the problem remains.
Neither of the following two fragments prevent a new window from launching after successful login to Discoverer Plus :
<iframe src="https://cohort50.spinsys.com:8251/discoverer/plus?framedisplaystyle=embedded"
width="100%" height=100%></iframe>
<iframe src="https://cohort50.spinsys.com:8251/discoverer/plus?framedisplaystyle=embedded&_plus_popup=false"
width="100%" height=100%></iframe>
Does anybody have any advice for me? What must I do?

Problem connecting Discoverer plus to Oracle 10g DB

I have a problem connecting Disocverer Plus to DB 10g.
DB 10g is located on a different server than Discoverer. All windows environment. When I enter DB name it gives me ORA-12154 error.
Question – I searched all the documents and it doesn’t say how to configure DB 10g to work with Discoverer. Could some one help me pointing me in a right direction? Do I have to create Data Warehouse or can I connect to the DB directly.
I added Database connection on the DB 10g listener. Do I have to do it on the BI listener as well. So complicated and no guidance.
thanks

In your Discoverer 10g home, navigate to:
$OH/network/admin
configure your tnsnames.ora alias's
or a shortcut... on Oracle BI Discoverer connection string enter:
username
pwd
db string like this (no breaks):
(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=yourmachine.domain)(PORT=1523)))(CONNECT_DATA=(SID = vis)))
There is guidance. The Discoverer Configuration Guide
or MetaLink Support notes.
The configuration guide specifically documents common problems
http://download-west.oracle.com/docs/html/B13918_03/tshoot.htm#sthref1287
D.1.4 Discoverer reports the error ORA-12154
OracleBI Discoverer reports error ORA-12154: Could not resolve service name.
Problem
OracleBI Discoverer cannot connect to the database alias specified by the connection details.
Solution
Make sure that:
the database alias is in the tnsnames.ora file on the middle tier
the database alias exists in the tnsnames.ora file on every machine that runs sessions
Hint: If you have SQL*Plus (or any other Oracle product) running on that machine, try connecting to the database with that product.
Hope that helps point you in the right direction.
Regards,
Steve.

Error on connecting to discoverer plus

I'm triying to connect to Discoverer Plus or Viewer. When I get to the login screen, fill all the required fields, but I got the following message: "The application encountered an invalid state.
- - Nested exception: org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 201 completed: No
OracleBI Discoverer Viewer was unable to find the necessary data for displaying the results of this event. Please correct any errors and try again."
can you please help me out so solve this prob.
the discoverer plus version is 10.1.2.48.18

Currently there is not enough information to realy de-bug the issue. I would look at the URL and verify that the URL with the connections page is the same as after entering the connection information. The URL can change if there is a Load Balancer or Proxy server involved.
Run the Discoverer script below to verify the Discoverer server is up and working.
$MidOH/discoverer/util > . ./checkdiscoverer.sh
Next look in the Discoverer application.log for additional information about the error. It is located at:
$MidOH/j2ee/oc4j_bi_forms/application_deployments/discoverer/oc4j_bi_forms_default_island_1
If these messages do
You are running an older release of 10g. The latest production release of 10g is 10.1.2.3 with Cumulative Patch 6 applied. See Note 237607.1 - ALERT: Required and Recommended Patch Levels For All Discoverer Versions. This Note is kept up to date.

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

Error connecting in Discoverer Plus/Viewer 10.1.2

When I run the checkdiscoverer. It works ok in all the checks except for: "Error: Failed to bind to Discoverer Server.
Hint: Try increasing the timeout by changing the timeout value in opmn.xml.". As the hint said I increased the start timeout, I got it up to 3500 and even incresed the minprocs to see if that helped. Nothing worked.
I'm testing this in a Windows XP Pro SP2 installed 1GB Ram. I Installed the BI Tools, App server but no infrastructure. The Installation process finished without any problems, except for a warning regarding not being able to determine the IP address. I can access all the options of the app server.

WLS Discoverer Plus fails to connect to database

I have Discoverer (server) running on a WebLogic Server but cannot get it to connect to my database. IE7 shows a page error in the lower left-hand corner when trying to connect from the Discoverer Plus login page. Displaying the page error shows a message like the following.
Line: 1
Char: 1
Error: Object expected
Code: 0
URL:http://myServer:7777/discoverer/plus
When trying to connect from the login page using Mozilla Firefox nothing happens, no errors displayed, nothing, just sits there.
I keep thinking this is an issue with IExplorer but not sure since Firefox does not connect either. Is there a particular log I should be looking at, if so then what should I be looking for?
Any help would be greatly appreciated.

Thanks, I have resolved this issue. It was a version issue with regards to the Fusion MiddleWare components I have loaded on my WLS. WebLogic Server 10.3.5 will not run versions of Forms, Reports or Discoverer that are lower than 11.1.6, at least that is what I found on my server. I had to patch my version of those components up to 11.1.6. All of these components now work fine. Thanks for your help.

I created a connection with Discoverer Admin 9.0.2, then uninstalled, and installed 9.0.4. Now, in Discoverer Plus the old connection is there, but grayed out and undeleteable. What can I do to delete this obsolete connection?

Hi Brian,
Could you please let me know how you managed to delete that obsolete connection ?
Thanks.
