Scheduling Workbooks on Discoverer Viewer.

Hello guys
I know you can schedule workbooks in Discoverer 10g Plus, but can you do this in Viewer? If not, then does this mean that we must give all our users Discoverer Plus so that they can schedule their own workbooks? Users used to schedule their own workbooks on Discoverer 4i. Now we are upgrading to 10g and we wanted to give them Viewer access. How do they schedule workbooks in Viewer?
Thank for all your help..

Hi,
In Discoverer viewer you cannot schedule reports though you can retrieve reports that have been scheduled.
Users that have access to Viewer will also be able to access Plus by entering a Discoverer Plus URL. The users privileges are stored in the EUL and determine what features the Discoverer user can access, not which tool they can use. So if the user has read-only access to the workbooks in Viewer then they will also have read-only access in Plus.

Workbook with Discoverer Viewer in Apps 11i?

With the help of (Doc ID: 278095.1) I was able to link Discoverer workbooks in Apps 11i. But all of my workbooks open with Discoverer Plus.
How do I open some of the workbook with Discoverer Viewer in Apps 11i?
I can open all my workbook directly with Discoverer Viewer without Apps 11i config.
Current Function Settings (in 11i) are:
Type: SSWA plsql function
HTML Call: OracleOASIS.RunDiscoverer
Thanks in advance for your help,

Hi,
Your workbooks are openned with viewer or plus depending on the profile 'ICX: Discoverer use Viewer'. You can override this by setting the viewer parameter on the call to OracleOASIS.RunDiscover. In the config of the Apps function that call OracleOASIS.RunDiscover, on the form tab add &VIEWER=Y or &VIEWER=N onto the end of the parameters. e.g workbook=myworkbook&parameters=param1~value1&viewer=Y
Hope that helps,

Scheduling workbooks in discoverer desktop

I'm trying to figure out how to schedule workbooks to run and export the output to a folder in Discoverer Desktop, I see in many posts that it can be done easily, I just can't figure it out, can anyone help?
I did confirm with my DBA that we do have the DBMS_Job package installed.
When I click on schedule as a user I get the following message:
A workbook cannot be scheduled for the following reason(s) - summary refresh 'job_queue_processes' parameter is 0
I would appreciate any help you can offer.
Thanks,
Janet

Hi Janet
You do not need to have DBA privilegs to schedule workbooks and any user should be able to do this. Here is an article from my notes:
Setting up Workbook Scheduling
The workbook scheduling feature in Discoverer uses native features in the Oracle DBMS, and is therefore only available when running against the Oracle database. This feature uses the same highly scalable and reliable processing procedures ithin the kernel, since the summary management capability and the setup for both features is similar. These procedures use standard packages in the DBMS called DBMS_JOB.
To enable the processing procedures for workbook scheduling in Discoverer, follow these steps:
A. Grant Schedule Workbook Privilege to the user.
B. Confirm that DBMS_JOBS has been installed.
C. Specify result set storage.
D. Set the time period at which the process kicks in.
These procedures are described in the following sections:
A. Grant Schedule Workbook Privilege to the User
The user must be granted the Schedule Workbooks privilege in the Privileges dialog. Connect to the Administration Edition, and grant the Schedule Workbooks privilege in Tools->Privileges dialog.
B. Confirming that DBMS_JOBS is Installed
1. Log onto SQL*Plus as the Administrator, and execute the following SQL statement:
SQL> select * from all_objects where object_name='DBMS_JOB' and
object_type = 'PACKAGE';
If the statement returns no rows, use SVRMGRL to create the necessary packages.
2. From Windows XP or NT, select Start->Run.
3. Type in one of the following:
SVRMGRL
4. When in the DBA facility, type CONNECT INTERNAL.
5. Execute the following SQL statement:
SQL> start <ORACLE_HOME>/rdbms/admin/dbmsjob.sql;
SQL> start <ORACLE_HOME>/rdbms/admin/prvtjob.plb;
C. Specifying Result Set Storage
When a scheduled workbook is run, the results are stored in database tables
within the database. Result set data created as part of the workbook
scheduling process may be stored in one of two areas:
the user's own schema or a centralized schema.
User's Schema
In order to enable workbook scheduling in the user's own database schema,
the user requires the following database privileges:
Create Procedure
Create Table
Create View
To grant these privileges, do the following:
1. Log onto SQL*Plus or SQLDBA as the Database Administrator.
2. Type the following:
SQL> Grant CREATE PROCEDURE to <USER>;
SQL> Grant CREATE TABLE to <USER>;
SQL> Grant CREATE VIEW to <USER>;
SQL> Grant EXECUTE ANY PROCEDURE to <USER>;
SQL> Grant SELECT on SYS.DBMS_JOB to <USER>;
SQL> Grant EXECUTE on SYS.V$_PARAMETER to <USER>;
where <USER> is the userid of the person who is to be allowed to schedule
workbooks.
These privileges must be granted directly to the user and not to a database
role.
Advantages: A database limit can be specified on the maximum amount of data a
user can store in the database. If the result set is stored under the user's
schema, then you keep control over the maximum amount of space one individual
user can fill with result sets. If the user creates a scheduled workbook that
fills that space, it affects only his/her own scheduled workbook.
Disadvantage: The user is required to have the above privileges in the database.
Repository User's Schema
In order to enable workbook scheduling using a centralized repository user's
schema, the SQL script batchusr.sql must be run in SQL*Plus or SQLDBA as a
database administrator (such as, SYSTEM). This script creates a new user that
is granted the above privileges.
In addition, the administrator of the EUL must change the user so that the
Repository User property is pointing to the repository user's schema just
created. The centralized repository user's schema may be customized by the
database administrator for space management purposes and underlying data access.
NOTE: SELECT ANY TABLE access is given by the script batchusr.sql,
but this may be limited provided the repository user's schema is
granted access to the underlying data that will be accessed for
workbook scheduling.
The repository user created will not be able to directly schedule a workbook
through the User Edition.
Advantages: Each user does not need DML procedures to run scheduled workbooks.
Disadvantages: One user can potentially run a scheduled workbook that fills the
available result set space, preventing other scheduled workbooks from running
until it is cleared.
D. Setting the Start Time for Workbook Processing
The workbook processes run within the database on the server, and are
controlled by parameters in the initialization file of the Oracle DBMS
- the INIT<SID>.ORA file.
To limit the number of processing requests that can run simultaneously:
The parameter job_queue_processes specifies the number of concurrent processes to use to process DBMS_JOB. It controls the number of processing requests that can be handled simultaneously. The default value is zero, which means processing requests will not be created. You should set it to a minimum of 2 or more if you have any other applications that use DBMS_JOB.
You need more than one job queue process, because if one job fails for any reason, it may keep getting re-submitted, and thus, prevent everything else in the queue from being completed. If you want to have 10 simultaneous processing requests handled, then you will need to set this to 10.
The INIT<SID>.ORA parameter job_queue_interval is the time in seconds that controls how often the job processes wake up to process pending jobs. The default is 60, which is quite frequent. What you set this to depends on how frequently you want the process to wake up and serve the requests that have been made. Oracle recommends that you update the 60 seconds default to at least 10 minutes (a value of 600).
NOTE: This parameter also affects summary management.
To enable these parameters:
1. Locate the INIT<SID>.ORA file.
For example, on Personal Oracle7 the INIT<SID>.ORA file is held in
<ORACLE_HOME>\database. Its default name is INITORCL.ORA where ORCL is
the <SID> name.
2. Enter 2 lines into the file. For example:
job_queue_processes = 2
job_queue_interval = 600 (equivalent to 10 minutes)
NOTE: The summary management and workbook scheduling features both use this scheduling capability within the Oracle DBMS. The interval you specify and the number of concurrent requests affect both features.

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.

Script to delete expired or errored scheduled workbooks for Discoverer

Hi All,
Can any one pont me to find a script to delete all expired and Errored workbooks in Database for discoverer?
Appreciate all your assistance.
Thankks

Hi Asim,
I don't think you can share the results of the scheduled workbook using Desktop. As for Plus, when you're signed on as the other user are you in the same database & eul and are you looking for "scheduled workbooks"?

Re-scheduling workbooks from Discoverer Admin

Hi All,
We have Discoverer integrated with Oracle Applications.
When logging into Discoverer Admin as EUL owner, it is possible to re-schedule workbooks scheduled by other users by navigating to 'Tools->Manage Scheduled Workbooks...' and clicking on the 'Edit' button for a workbook. It allows to change date/time of when the report should be executed and successfully updates the Discoverer meta-data tables in the EUL. However, the dbms job associated with the workbook is not re-scheduled, so the report is executed at the original time.
I am not very familiar with the Discoverer, but my feeling is that it is not properly configured in our installation. Any advise on how to fix this issue would be greatly appreciated.
Thank you.
Denis

Hi,
You can move the workbooks by using a Discoverer export/import from Administrator.

Parameters disappear when trying to run a workbook in Discoverer Viewer

Please help! We have a number of workbooks that were working previously, but have started exhibiting this strange behavior for certain users. They go to Discoverer Viewer, select the desired worksheet, and enter their parameters. When they hit Go, the form immediately resets; no results are returned, and all of the parameter fields are cleared. Can anyone tell me what's going on?
-Dave

Hi Dave,
I had a similar issue awhile back. It was related to the item class for the input parameter. The item class was being built off a table that the user was not given access to. This was in a data warehouse environment. Maybe, it's just a matter of granting access to the table for the user.
Regards,
Nancy

Unable to delete workbooks in Discoverer Viewer

Hi All,
I could not find any option in Viewer to delete the workbook created by me. Does that mean, users can only save workbooks but cannot delete them in Viewer?
Thanks.

Hi
RE: Oracle gotta see what mess is created after saving the workbooks in Viewer I agree but you are going to have to take some of the responsibility because you allowed the Viewer users to have access to the save privilege.
Please see Russ' excellent comments. Russ and I see eye to eye on this and I endorse his comments 100% - you should not allow Viewer users to save - period. Russ and I have over 20 years of experience on Discoverer between us and rarely do our opinions differ by very much. This is not surprising because if there's a right way to do something - there's a right way. Sometimes there's an alternative way but rarely are there two right ways.
The right way to manage Viewer is to withdraw the save privilege from the Viewer users. This of course would not prevent a Plus user from saving in Viewer but it will stop the mess that you are seeing today. Thus, the solution is not to add the delete functionality but to withdraw the save functionality.
In my experience, Viewer usage should be high, somewhere between a 70:30 to 90:10 ratio when compared to Plus. Because of this high number of users, it is also vitally important that they get trained well on the Viewer tool. Too many companies fail to invest into Viewer training and they suffer greatly because of it. In a lot of companies they assign the training to one of the Plus users, someone who a) is not a trainer, and b) does not know the Viewer tool inside out and back to front.
I'm not for one second saying that you are in this situation, just saying that this is what typically happens. The end result though is user dissatisfaction which leads to misuse of the system and ultimately on to disuse of the system, with everyone either going back to their old Excel way of working or being granted access to Plus.
You're definitely on the right path if you are using Viewer so please keep going. Its a great tool for what it does - viewing of reports. You just need to reel in some of that power.

Discoverer Viewer and Scheduled workbooks error

Hi
Hope someone can help.
I am scheduling workbooks in Discoverer Plus 10.1.2.48 with the intention of viewing them in viewer.
The report shows itself as running okay in Admin, but when I open the report in Viewer or Plus I get errors including:
ORA-03106 Fatal two task communication error
or
"unable to generate sql for this scheduled workbook"
I suspect they might be retrieving fairly large result sets (10 K rows +)
Please can anyone offer advice on how to resolve this?
Many thanks

Hi Tim
Well just the way the file is put together, like is it using SID= or SERVER=, does it use SERVER=DEDICATED, do you have one ADDRESS= or multiple?
To make sure everything is right, rename both TNSNAMES and SQLNET.ORA files, then suse Net Configuration Assistant to set up a connection. Then compare that with what you have already and make the necessary changes.
I also noticed that Russ has made a posting concerning a similar error. You should take a look. Its either in here on the Discoverer forum.

Discovere viewer and scheduled workbook

I scheduled a workbook to run nightly. If I open the report, that belongs the scheduled workbook, in Dis Viewer, why Discoverer re-run the query again??? This defeated the purpose of scheduled workbook.....

Yes. That is what I understanded. But when in a SQLPlus session I captured SQL statements of both unscheduled and scheduled reports and they both run the same SQL statement

Hi
Thanks for this. A couple of things come to mind. First, it looks like you may have done more than one installation of the Discoverer 10g Admin / Desktop Install and it also looks as though you have an older Discoverer sitting out there, presumably a Discoverer 4 version. How did I spot this?
Firstly, the name you are using for you 10g installation is BIToolsHome_2. This tells me that you either have 2 or you had a failed install number 1. If you happen to be calling the executable from the first install with the PATH set to the second install this will cause a problem.
Secondly, Discoverer 4 always installs using the ORANT folder.
I am not sure what you have inside d:\oracle\bin or even in c:\oracle\discoverer\bin. These could definitely be causing problems elsewhere but probably not impacting Discoverer 10.
10g Discoverer Admin / Desktop needs these 4 entries in the path and these are there, albeit againt BIToolsHome_2 and not 1:
C:\oracle\BIToolsHome_1\bin;
C:\oracle\BIToolsHome_1\jlib;
C:\oracle\BIToolsHome_1\jre\1.4.2\bin\client;
C:\oracle\BIToolsHome_1\jre\1.4.2\bin;
First things first, we need to verify that you don't have an old version 1 hanging around.
Right-click on the icon to start Admin. In your case it should look like this: C:\Oracle\BIToolsHome_2\bin\dis51adm.exe
Right-click on the icon to start Desktop. It should look like this: C:\Oracle\BIToolsHome_2\bin\dis51usr.exe
Please verify the above and let me know if everything looks right.
Best wishes
Michael

Scheduling workbooks using the command line

Hi, can anyone tell me if it's possible to schedule workbooks in Discoverer using the command line interface? If so, could you point me in the direction of any relevant documentation?
We've got 300+ reports to schedule on a regular basis and it would be useful if we had different options to schedule the workbooks e.g. for batch processing.
Thanks and regards
Geoff Butler

Inspired by your MacOS fix, I went looking to see if their was an easier Windows fix than my 'Repair Bonjour' process. Turns out there might be.
In the Bonjour 'Program Files' folder, there is an application named 'mDNSResponder.exe' which brings up a DOS dialog. After running this application and then opening iTunes, I had a stable AppleTV-iTunes connection through the evening until I put my computer to sleep.
I haven't done any thorough testing around this (the kind that Apple should have done before releasing iTunes 7.6), but it does seem to at least temporarily resolve the issue until iTunes is closed again. What would be nice is if this works without having to restart a faulty iTunes session (which the 'Repair' fix doesn't).
