Accessing Discoverer Viewer on a PDA

Hi,
Could anyone tellme if it would be possible to access discoverer viewer on a PDA running windows mobile 2003?
We have a Portal running the discoverer portlets and when I click "Analyze" link the discoverer viewer errors with a java null pointer.
Has anyone tried this?
Also, I assume that I may need a JVM on the PDA?
Thanks
Joel.

Again, there is no way to do such thing. It is mainly because MIDP target a large range of mobile products which not necessarily have those address book or other databases.

Workbook works fine in discoverer plus but shows error in discoverer viewer

Hi,
I have some issues with the parameter of a report.
one of the parameters is
mgr_id (eg: 1,2,3) -- from database table.
manager names are not available in the database but they are known to users like
1 - david
2 - alan chris
3 - peter
so the requirement is
(i) the input parameter wud be entered as 1 or 2 or 3 or null ( or in multiple combination or all).
But the report shud have parameters in the header of the report.
for eg: if the input parameter is mgr_id = '1' then the report shud have manager name: 'david' in the header.
if the input is mgr_id = '1',' 2', '3' then on the report header, it shud display as manager name: 'david','alan chris','peter'
(ii) the default value of mgr_id shud be 'ALL'. if the user enters mgr_id as 'ALL' then it shud take all the values of mgr_id and pull all the values of mgr_id (like 1,2,3)
and the report header shud display as department name: 'ALL'
i have developed a custom query where i used,
select dept_id, decode(mgr.mgr_id,'1','david','2','alan chris','3','peter') as mgr_name, ..... etc.
in discoverer admin,
I have created LOVs (item classes) for mgr_name.
after that going to properties of mgr_name, i have selected mgr_id as indexed item.
and in the report i have created parameter dept based on mgr_name and selected the option -- allow to select both indexes and values.
and in the default value i mentioned 'ALL'.
after that i changed the condition as
((mgr_name = :manager name) OR (mgr_name LIKE DECODE(:manager name,'ALL','%')))
and in the header, i used &department name --- then it displays correctly.
but the problem is ---
the report works fine in plus. the problem is only when parameter value is 'ALL'
when i run the report from discoverer viewer for the very first time (after logging in), the report works fine with correct data.
but when i run the same report second time with parameter value 'ALL', it gives an error ---
Invalid value "''" for parameter "department name"
i dont understand, why it works for first time and doesn't afterwards. If i logout and login again, it works fine in viewer.
am i doing anything wrong in conditions or declaring the parameters?
I came to know that, the very first time, when we enter 'ALL' it is taking '%' but when we run for the second time, it is taking NULL. since NULL isn't there in mgr_id or mgr_name, it is throwing that error.
How do i fix this error?
Thanks

Hi Puppethead,
I have tried with your suggestions.
the following condition -- did not work
( (mgr_name = :manager name)
OR (mgr_name LIKE DECODE(:manager name, 'ALL', '%', NULL)))
but for the other condition ---
( (mgr_name = :manager name)
OR (mgr_name LIKE DECODE(nvl(:manager name, 'ALL'), 'ALL', '%', NULL)))
is wrong because, :manager name cud be null, when it is null, it takes 'ALL' i.e. '%' which shud not be the case.
if the user enters null, it has to display records with null only but with the above condition it takes '%'
The main issue which i dont understand is, the report works fine for the first time. for the second time, the report takes null values . why is it taking null values for the second time.
Thanks

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 all,
we recently installed the patch for web services in discoverer.
But since then we've been getting a strange exception. Have you seen this before, or know what it is? The exception is resolved after a restart of the server. I'm getting it when I try to view http://host:port/discoverer/viewer for example.

URGENT!! Drill Down Error with Character Set non-ascii on Discoverer Viewer

Hi,
We have an error in a Drill down. It comes up when the Discoverer Viewer tries to process data that contains special character (non-ascii) in a query's filter. The same report that does not perform well with special characters, does perform well if the data dont contains special characters, so it seems to be an issue processing non-ascii chars in this Discoverer Viewer instance.
Ex. FIELD_NAME = 'Ã¶ÜÃ¦Ã¤é (This filter is contained in a query that this getting an error msg="We're sorry, the server encountered an unexpected condition" ).
It might be possible that there are some problems with the Discoverer charset ?
We will appreciate any suggestion about this respect.

Seba.

HTTP 500 - Internal Server Error from Discoverer Viewer to Portal

HI,
I created a tab with a list of workbooks created with Discoverer Viewer and published with Discoverer Portliest Provider (List of Database Workbooks). Another tab contains four Discoverer Worksheets created with the same account. Everything works well but if i click on a report in list and open Discoverer Viewer, when i return to portal and go to tab containing worksheets i see message "HTTP 500 - Internal Server Error" and i'm not able to do anything. I only can close my browser and i must reconnect to portal!
Can you help me?
My portal version is cg (9.0.4), i'm using Windows 2000 ESP and Internet Explorer 6.
I tried with Olin and Mazola but result did not change.
I used a public connection bud i tried a private connection too. Nothing happened.

The application.log file, under the OC4J which running your Discoverer provider, should give you some hints about the problem you're facing.

Discoverer 4i Viewer Error

In our company we installed the Oracle Discoverer 4i Early Adpator and, when we try to use the Discoverer Viewer, an error occurs.
This error happens when I apply the parameters of a worksheet and the symptom is like a download of a file, named "ca54zrse.txt". The content of this file is:
"java.lang.NullPointerException
at oracle.discoiv.session.model.ModelQuery.run(ModelQuery.java, Compiled Code)
at oracle.discoiv.session.model.ModelQuery.run(ModelQuery.java, Compiled Code)
at java.lang.Thread.run(Thread.java, Compiled Code)"
When it occurs, the connection with the database is dropped and I have to connect again.
I'm using Oracle Database Enterprise version 8.1.7.
What can I do? Is it a network error or a database error?
Please, help me!

Invalid state error when using concurrent sessions in Discoverer Viewer

We are oracle 10g DB for Oracle BI Discoverer Viewer application.
We have a problem when a user logs in with the same ID on two different sessions under one machine(1 mac address).
The error message is as per below.
====================================
"The Application encountered an invalid state.
No state was found matching the state identifier provided. This can happen if your session timed out. Please start the operation again.
Indez: 10, Size:0"
====================================
The index and size varies at different times.
We suspect that the problem's caused by a confusion between the StateIDs of the two sessions. This can be replicated by modifying the querying URL; by manually changing the value of the StataID parameter.
It will be good if somebody can help us on this...
Regards
Albin Abraham

Are you using the same browser for the two sessions? I have seen instances where the user opens, say, IE, connects to Disco, and runs a worksheet. They then open another IE window, start another session, and run a different worksheet. What I believe was happening (and I'm not sure because we told the users to stop doing this) was the second browser may have tried to "reuse" the java session started by the first browser. When you went back to the first browser, it no longer had a valid session because the second browser had taken it.
To have to independent sessions, I'll start one in IE, and another in Firefox, or Netscape. This keeps the sessions from getting mixed up.
Then again, I could be wrong...

Error in Discoverer Viewer - Item cannot be found

Hi,
When i run a work book in discoverer viewer i receive an error "The following Item cannot be found: Workflow Item Attribute Values.Item Type. The same report is working fine from Desktop. Can anybody suggest what could the problem be?

Hi,
The issue is resolved. The access to the underlying business area was not given to the user though the responsibility was assigned. Hence the error.

Error messages from Discoverer viewer in others languages (Greek)

Hi, I'm using Discoverer Viewer 10g and I set the browser in order to see only Greek language.
When I don't write a mandatory parameter into the initial parameter form I receive an error message as
"parameters required for TASKS_CREATE_DATE_LL" (in English)
where TASKS_CREATE_DATE_LL is the parameter requested.
While for the LOV parameters the error message is written correctly in Greek (and shown into a form from the browser), for the normal parameter, as above, the error message is ONLY in English and written just under the parameter text box....
Is there a way to show these errors also in Greek (always under the parameter text box) ?
I also checked the pref.txt, but I didn't found nothing to set a language...
Thanks in advance for your help
Alessandro
