VPD and discoverer portlets

Hi,
Resolution History
23-MAY-07 16:53:02 GMT
### What kind of problem do you have? ###
Security Issues
### Describe the problem you are having in detail. Include any notes, guides, or documentation
that you have followed. ###
We have test implementation of VPD or row-level security at database level. This works fine with discoverer queries. At the
portal level we are okay with getting discoverer portlets via a public
connection (the VPD works fine).
Q1. What kind of parameter form would be better for discoverer portlets so that we retrieve list of values via a sql query? Simple parameter form allows static list of values so any suggestion on what parameter would be good and easy to implement to write sql queries.
Q2. With parameters form of some kind we are trying to limit the list of values for each parameter that we have at the portal based on the user logon at the portal somehow married up to database users. (FYI-- we don't have SSO for discoverer). Any suggestions as to how this can be implemented also would be greatly appreciated!
Thanks in advance,
-Esther

I really hope someone can help! I'm trying to accomplish the same exact thing! The private connection for each user gets tricky because not all of our users know exactly what they are doing. Please help!!

Oracle Portal and Discoverer Integration

Oracle Portal and Discoverer Integration
We're trying to integrate Discoverer with Portal unsuccessfully.
We made many things in accordance with oracle's documentation until add discoverer portlets (worksheet and list of workbooks) in a test page.
In view mode, the worksheet portlet shows the error:
"The portlet has not been defined. The publisher must define the portlet by clicking on Edit Defaults for the portlet on the edit mode of this page. Please contact the publisher of this page."
We think we have to edit properties before. Is this? Anyway edit worksheet portlet crashes between step 1 and 2. The error is: "The listener returned the following Message: 500 Internal Server Error".
We have a public conection created in EM and a discoverer application which can be viewed using plus or viewer.
Furthermore, it's not possible delete the added portlets neither the page that contain it. The error at delete is:

Hi there,
Have you applied any patches to 9ias since it was first installed? We had the same problem and had to apply a couple of patches to get the portlets working.
1. Apply the 9.0.2.53.16 one-off patch for Oracle 9iAS Discoverer which takes Discoverer up to 9.0.2.53.16. This patch appears to be password protected and you need to get someone at Oracle support to give you a password.
2. Apply the Discoverer Portlet Provider: 9.0.2.53.00c patch (patch no. 2595444) which gives you a new discportal.xsl file that actually works. It's this second step that solves your problem but you need to do step 1 before this. This is password protected as well.
3. As you've upgraded Disco on the server to 9.0.2.53, you'll need to upgrade Disco Admin & Desktop within your 9iDS installation using patch no. 2555265. This is because Disco 9.0.2.53 uses an upgraded EUL that Disco Admin & Desktop need to be patched to use.
This was the course of action Oracle support advised us about nine months ago. Of course they may have released a further patch to Disco that does 1 & 2 in one go, but we regularly carry out steps 1 and 2 on servers we use and we can use the Disco portlets successfully.
Hope this helps

Slow performance of discoverer portlets

Hi,
I am running into slow performance of a particular page in portal, there are multiple sites hosted on the portal but these all have static text and are very quick to load but the one page with discoverer portlets and a web-clippping portlet is taking ages. If I run these reports on their own they are instant. Has anyone had similar problems with 9.0.2 portal and the discoverer reports ? I tried to identify a particular report that may be the culprit by deleting them one by one and to no avail. After a few hours effort I found the design mode was hanging as well. Again, just for this 1 page.
There are 3 tabs on this page with about 4 report portlets and 1 web-clipping portlet.
Thanks for any help,
Brandon

Thanks for the help.
Seems to have been resolved although I'm not sure if thats the end of the story. Will wait and see.....
So far apparently a port conflict of some sort in the discoverer config was causing it to hang and then also other system demands on the network and server housing the discoverer end-user layer were also causing problems.
No error messages unfortunately......

How to change Refresh Time in a Discoverer Portlet?

Hi,
I have added a discoverer portlet to my main portal page. The minimum refresh time for the discoverer page i could set is 1 hour. Is there any way i could change it to 1 min as this is getting real time data in the database which i would like to display immediately.
Any help/suggestion is most welcome. Thanks in advance.
Regards
Goutam

Hi, i have the same problem.
i have searched both metalink and here but found nothing .. doesnt anybody know how to change the discoverer portlets refresh time interval anything other than 1 hour,1day,1week etc. (they are the only options available)
Any help would be appreciated.

Portal integration with E-Business and Discoverer 10g

Hello Everyone,
We have a R12 integrated with SSO/OID. We also have a standalone Oracle BI Discoverer 10g. We want to implement Oracle Portal here. One of the requirements of this project is to have a common home page for both E-Business Suite login as well Discoverer access. Right now E-Business Suite login is seperate and Discoverer home page is seperate (because it comes from a Standalone installation)
1) What are the benefits of having AS Portal 10g for end users ?
2) To begin with, we would like to go with the minimum portlets.
3) Is it possible to have a common home page for both E-Biz access and the Discoverer acess after Portal integration ?
4) Do you have some screenshots of how things look after Portal integration
-Thanks
Srinivas

Hi,
take a look in metalink Note:313418.1. :
"Using Discoverer 10.1.2 with Oracle E-Business Suite 11i"
Look in section 6 - post installation.
Follow the steps and have a very good luck.

Registering Discoverer Portlet Provider with JDeveloper WebCenter

Is it possible to register DPP with JDeveloper? What kind of portlet producer is DPP, WSRP or Oracle PDK? Can anyone tell me the specific steps (i.e., what to fill in for the URL, subscriber ID, etc.)?
Thanks,
-warren

You might want to ask this on the Discoverer forum.
It depends on the type of portlet DPP is - JDeveloper can register both WSRP and PDK portlets.

Success with export/import of Discoverer portlets?

Hi folks.
Before I begin working with the 9iAS export/import procedures, can anyone tell me if they've been successful exporting and importing pages with Discoverer portlets from one 9iAS server to another?
Are there any gotchas?

Ravishankar,
Thanks.
So are you saying:
Pages with Discoverer portlets will be transported with the Discoverer portlets in place.
However, after the transport, the end-user will have to "Edit Defaults" again.
And user customizations would have to be re-applied.

Discoverer Portlet security

Once a discoverer portlet has been added to portal, only the user that added the portlet can edit it. The only workaround I can think of is for all administrators to use one generic user to add and edit discoverer portlets.
Does anyone else have ANY other suggestions?

Got it...i can figure that out using fnd_global.resp_id.
Thanks

Exporting and importing portlets

I have be able to run the export option from the application wizard to extract a portlet from one Oracle instance. And I am able to import that portlet into another instance of the portal. However, this appears to work only the first time, when that particular portlet does not already exist in the new instance. When I try to import it again, as if I were making a modification to a portlet in development and then importing it into production, it fails with a unique constraint violation and Im instructed to rename the application. This is pretty inflexible and Im wondering if Im missing something basic here. How do I replace an existing module with a new version, without having to delete the existing one so that it can be replaced?

Ravishankar,
Thanks.

AS 10g SE now includes Reports and Discoverer?

I've read some articles about the "new" AS that it has been "re-packaged" (licensewise) and that the BI stuff like Reports and Discoverer are included in the Std Ed. Also (in the FAQ I think) that some EE stuff has been moved "down" to SE - sounds promising! But I have not been able to verify this... Anyone out there?

I urge Oracle do the same for Discoverer.
We have been using Discoverer since 3i. This year, we had some people on 3i still and some on 4i. We went through the conversion to 4i and no one is using 3i at all now. These people are very used to how Discoverer works. They are used to using database authentication and security to workbooks.
The Infrastructure can store connection information for each user. By default, it stores connection information in cookies on the user's machine but you can configure the Infrastructure to store this data for you. The Infrastructure also stores metadata for Discoverer Portlets (Portal required).
So that is it. If you are not using Portal nor care about storing connection information in a database, then why even have the Infrastructure for Discoverer? Just like Reports and Forms, if you aren't using SSO or Portal, there is no need for the Infrastructure and Oracle should provide an installer to let you install Discoverer without having the Infrastructure sitting there.
Here is the doc on Metalink that explains what the Infrastructure does with Discoverer 9i.
http://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=224871.1
I also spoke with John Entenmann at ODTUG in Miami this year and asked him if Discoverer works and is supported in an install without the Infrastructure. He agreed that if you are not using Portal or SSO, you don't need the Infrastructure with Discoverer 9i.
Now Oracle needs to support Discoverer customers in the same way they are going to support Forms and Reports customers by providing a more reasonable installer that doesn't require the Infrastructure to be installed first.

Discoverer portlet error: blob content is empty.

I created 6 disco reports and some are giving error, Failed to retrieve an entry from the cache in the Discoverer Portlet Repository. The BLOB content is empty.
This error only happens with certain users. The users can log directly into discoveer viewer and see the reports. Just not in portal. It also gives me this error randomly and I have to delete the portlet and recreate it. Has anyone else experienced this problem.
BH

I copied and pasted the above code to my jsp. It works fine for me . I get the content correctly. Tried on a ps 7.1
hope the additional character "/>" is not intended
<td>city</td><td><input name="city"value="city"/>/></td>

Refreshing Discoverer Portlets

Using 9iAS R2, we have set up discoverer portlets on our intranet and have serveral scheduled worksheets which display within portlets.
On one report I have scheduled it to run once an hour and I have also set the Discoverer worksheet porlet to refresh on an hourly basis - which it seems to do.
However, the data is not updating at all. It is only when we actually open the worksheet using Discoverer Plus and save that data in the Portlet refreshes.
When users click on the 'view worksheet' link and open Discoverer Viewer the correct data appears
Perhaps I have missed something . . is there another way to ensure that the data shown in the portlets is refreshed?

I believe that the refresh is set as a DBMS_JOB in the database, however, I have no clue where this is set, obviously somewhere in the product and/or identity metadata database depending on your configuration. Something that might be an easier solution is use something like HTTPClient from the Apache Foundation (http://jakarta.apache.org/commons/httpclient/) and write a small app that logs into portal as an administrator and then calls each portlet's refresh URL in order. It know its a workaround, however, it should work, that being said I've never tried it. I don't know if I'll get time to write it, but if someone gets a chance to write it before I do please shoot me the code :P

Discoverer Portlet Refresh Date

I have a Discoverer Portlet on a Portal page. Is there any way I can hide or not show the Last Refresh Date and Next Refresh Date from Discoverer Portlet?
Here's an example:
Graph or Gauge displayed and then at bottom there is:
Last Refresh Date 3/31/06 10:46 AM
Next Refresh Date 4/1/06 9:01 AM
Thanks in advance,
-- asit

If anyone's interested, i found a blog that shows how to remove it.

Discoverer Portlet fails with ora-01017

This is about OAS 10gR2
Middle tier version: 10.1.2.0.2
Discoverer version: 10.1.2.48.18
I've manually changed password for Discoverer EUL Owner schema (using "alter user blablabla identified by blablabla" statement, in sqlplus) and now I can't register discoverer portlet provider.
It fails with the following message:
"Error!
BaseException is ... ORA-01017: invalid username/password; logon denied
Recognizing component versions...
ptlshare.jar version: 10.1.2.0.2
pdkjava.jar version: 10.1.2.0.0"
I make no idea what was the password for discover5 schema before and that was the reason i changed it.
Already have redeployed discoverer.ear file in OAS administration, but it didn't change a thing.
I've tried the Discoverer Forum but no one there answered my question.
Any ideas of what could bring this kind of issue?
TIA
Marcos

Solved!
The problem was that when I changed user password in database, i did not synchronized Database user with OID attributes.
Step by step solution:
Reset Password for DB user in sqlplus with
"Alter user XXXX identified by YYYYYY;"
Enter OID (Oracle Directory Management) as the "superuser" (ORCLADMIN);
Navigate to
-> Entry Management
-> cn=OracleContext
-> cn=Product
-> cn=IAS
-> cn=IAS InfraStructure Databases
-> cn=orclReferenceName=appsdb.ecovias.com.br
-> OrclResourceName=DISCOVERER5
Alter orclPasswordattribute for the user, using the same password you have resetted in Sqlplus.
Bounce OAS middle tier instance (ompnctl startall/stopall or using Application Server Control).
Touché, it's done!
Alternativelly, you can keep geniuses away from altering passwords...
Thanx y'all...
