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

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!!

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?

Any help/suggestion is most welcome. Thanks in advance.

Any help would be appreciated.

Can I put Discoverer Portlet in my web application? Let's say I want to put or publish worksheets it in my own J2EE web application (not on Oracle AS Portal)
Please comment on this.
Thanks.

Pass page parameter to discoverer portlet

Hi All,
iAS Version 10g(9.0.4)
I created worksheet(graph) using Discoverer plus having 4 parameters. I published the
discoverer graphs as discoverer portlet in Oracle portal. However for this worksheet it shows
(No parameters) in Page --> Properties --> parameter. I created simple parameter portlet with
4 items, this entry I need to pass to this discoverer portlet/Worksheet.
Any suggestion would help.
Thanks

Hi,
Thank for your reply.
We are using discoverer plus for relational data (Oracle 10g (Ias 9.0.4)).
Appreciate your feedback.

Hi, are you using discoverer plus for relational/OLAP

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.

Error editing Discoverer Portlet 'Edit Defaults'

Hello,
I am trying to edit my discoverer portlet to change the refresh options. However, whenever I click the edit default link, the following error message shows up on the page:
The current user does not own this instance. Only the owner can Edit Defaults for this portlet. Please contact the portlet owner
This happens even though I log in as the portal admin user.
Any ideas?

Did you find a solution to the problem? I am encountering the same problem. If the discoverer portlet is created by somebody else then I am unable to edit the defaults.

Apps 11i, Discoverer, and Security

Just an FYI for those out who are having problems picking up Apps Security when trying to implement Oracle Discoverer on top of Apps 11i. We have struggled over the past six weeks to have Discoverer pick up Apps Security and have finally found a combination that works. If anyone else is having a similar problem and would like the details of our configuration, please e-mail me at [email protected]

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,

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...

Add a Help Link to a Discoverer Portlet

How can I add a Help Link in a Discoverer Portlet?
Even if I have checked the 'Show Help Link on Portlet Headers' in the Portlet Display Options this does not appear in the Portlet.

Hi.,
As far I know it is not possible to create URL link in Area Menu., instead, Create a Report and call Function 'CALL_BROWSER' and pass the url to the function module.
Now create a Transaction for this report let say ZURL,
Now Assign this transaction to Area Menu So., When you click that transaction in Area menu it will open Url in browser.
hope this helps u.,
Thanks & Regards,
Kiran
