Discoverer Plus for OLAP

Hi....
Our company had installed Oracle Application Server 10g and using Discoverer Plus 10g (10.1.2.48.18) and also creating the EUL as the data storage/mapping for our workbooks/reports.
Our company has a plan to use Discoverer Plus for OLAP and already installed the discoverer catalog.
How to create a connection using option "Connect To" OracleBI Discoverer for OLAP ?
What is the diffrence between Discoverer Catalog and Analytic Workspace?
What tools that we must use to create data for OLAP (to create some dimensions, measures etc)?
Any Help will be appreciated
Thanks,
Handoko

Hi Handoko,
You can establish a connection from Discoverer Plus for OLAP, by specifying the database connect information in the form of HOST:PORT:SID (e.g MyServer.com:1521:orcl10g).
The Discoverer OLAP catalog is used to store end-user reports and is installed and maintained using Application Server Control console. It allows you to install the catalog and authorize users to store reports in the catalog. The Analytic Workspace Manager is used to define your multi-dimensional model and load the data from source tables.
Mark Rittman provides some indepth documentation, have a look at the link below :

Has Discoverer Plus for OLAP any future?

Has Discoverer Plus for OLAP any future?
It only one desktop product for Oracle OLAP, but no evolution last time and require more functionality.
anybody tell about?

The patch number for 10.1.2.3 is 5983622.
Currently it is available only for Win32 and Solaris. I'm told that it will be available on other ports sometime in April.
Also a word of warning - 10.1.2.3 does not contain the fixes released for 10.1.2.2 in CP4, CP5 and CP6. There will be a one-off patch released shortly for 10.1.2.3 containing these fixes.

Use short label in disco PLUS for OLAP report

Hi All,
I've noticed in the spreadsheet add-in you can decide under "query options" whether to use the Long or Short Description when displaying a dimension member. How do you do the same in discoverer PLUS for OLAP ? I cant find it anwhere.
Cheers,
Brandon

Hi Brandonm,
You currently do not have this option in Plus to have use the Short, Long labels.
I think this is planned for a future version, maybe in 11 we will have this.

Installing BI Discoverer Plus for multidimensional OLAP ?

Hi there,
it seems I really need to ask for help after getting lost in the forest that Oracle Software is. I hope my question is not too bothersome to people on this forum. So here's the situation:
I have an Oracle 11g database on a CentoOS server, with OLAP option. I have created a simple star schema from my data and an analytical worksheet (although not without pain, there's another thread about that). Now I wish to access the OLAP data through a tool on my Windows XP workstation and be able to manipulate the data to create reports. My goal is to create a small demo to help convincing our client that OLAP reports is the way to go to play with their data, create custom reports, etc. In fact what I'd like to do is to play with the OLAP model like I used to a few years ago when I was using Business Objects as as client, I think they called it Universe Management or something. The thing is you get your model elements (measures, levels, attributes, etc) as icons in a palette and you can drag&drop them on a worksheet to dynamically create reports, crosstabs, etc. That was very nice and accessible to almost any user.
Now my question: what piece of Oracle software should I install on each machine to be able to do that ? I tried with Oracle Client BI Tools on XP but this seems to only include Discoverer "classic" or whatever, that only manipulates relational data. I think I need Discoverer "plus", but where is it located ? This is what I found on the website: "OracleBI Discoverer can be installed from the Oracle Business Intelligence CD". Well ok, but which CD ? There seems to be several of them, like Oracle BI EE, Oracle BI SE, Oracle BI SE One, Oracle BI Tools, etc. Additionaly do I really need to install a full-blown Application Server on the CentOS system to access Discoverer Plus ? This frightens me a bit, you know, I'm aiming for a small demo with two or three tables, I'd be thankful not to have to spend a whole week installing a web infrastrucutre for that.
Well this all looks somewhat confusing, so I thought I'd be better off asking those who know, hence my post. Again I hope this doesn't sound to bothersome.
Thanks for your help!
Christian

Hi Gareth and all,
in fact I have installed the "Oracle BI Tools" for windows (as_windows_x86_bi_tools_101202.zip) which give me access to
- Oracle Discoverer Administrator
- Oracle Discoverer Desktop
However according to the [Discoverer documentation|http://download.oracle.com/docs/html/B13917_03/1intro.htm] these are not the tools I'm looking for; as it says : "if you want to create new worksheets and analyze data from both relational and multi-dimensional data sources across the Web, you will use Discoverer Plus". As it seems, Discoverer Desktop only accesses relational data through an EUL, I really would like to play with my OLAP cube, because I'm intending to create a demo of what will eventually be a much larger OLAP system.
So I'm still desperately looking for Discoverer "Plus". From the page you indicate I had already installed not the full AS but the "Business Intelligence" CD, which is supposed to include Discoverer (as indicated in the 'Included" list). I did a "complete" install, however I'm still unable to locate anything ressembling Discoverer. I have Publisher, Dashboard, Delivers, Marketing, Disconnected Analytics... There's Answers that might be similar to Discoverer, but it looks like a whole different beast and much more demanding (like I'm not even able to figure out how to define a new data source). Well I was hoping to be able to view my tiny cube in a few clicks and "Discoverer Plus OLAP" looked like the right tool for that.
So the next step might be to install the full AS, however it'll take the whole week-end to merely download the 4 CDs. And will it include Discoverer PLus in the end, or am I getting to come back empty-handed again ? Well this is all getting a bit discouraging, please if anyone here knows a convenient way to end up graphically manipulating an OLAP cube and creating simple reports from it please advise ! :-)
Anyway thanks all for your support,
Chris

OracleBI Discoverer Plus OLAP

Hi
I need to use Discoverer for OLAP. I have installed BI and BI Tools, but I have there only Discoverer, not Discoverer Plus..
I dont understand where can I get Discoverer Plus...
Please help.
Thanks

Hi Aparna
You're obviously using Discoverer 4i which uses an older method of connecting. In this method you have to supply the full path and file name of the file being used to launch Discoverer on the URL. You have no choice but to run this path. However, you could create a proxy for it.
In newer versions the path and file name are all embedded configuration files within the application server, thus you only have to pass a port and the application name. The system then looks in its configuration files to determine the path and which file to run.
Having to use Netscape rather than IE is one of the oddities of 4i. While the IE connector may well work, it was noticed a long time ago that the Netscape file was far more robust. This is because when 4i was written the version of IE at the time was 6.0.28n pack 1 which could not handle JInitiator very well when called using standard IE commands. Seeing as the IE of the day could run the Netscape commands, the rest is history.
By the way, as a side issue, you need to upgrade ASAP because 4i is about to be desupported. I place a new posting on my blog last night which might help understand the Discoverer versions:

Problem with opening discoverer plus by URL

Hi Gurus,
I am opening the discoverer plus worksheet using a URL from another web page to skip the connections page. Heres the hyperlink, I am using for the same
http://burs52:7779/discoverer/plus?&_plus=true&nlsl=en-us&cn=cf_a122&lookandfeelname=system&workbooksource=Database
This would directly bring the 'Open workbook from Database' page with list of workbooks for the particular connection, but the problem is that every time it opens the discoverer plus it would automatically open the connection page(http://burs52:7779/discoverer/plus?) in the parent window(webpage with the hyperlink). This would confuse the end user.
Is it possible to avoid this? i.e keep the parent page unchaged
Thanks in advance
NJ

What version of Discoverer are you running? I'm assuming 10.1.2 but I would look at the 2 URL parameters
pluspopup and framedisplaystyle
From the Oracle Documentation:
When using popup in conjunction with framedisplaystyle=, the possible combinations are:
pluspopup=true and framedisplaystyle=embedded launches Discoverer Plus in a new pop-up browser window that contains the Plus applet embedded in it.
pluspopup=true and framedisplaystyle=separate opens a new pop-up browser window and launches Discoverer Plus in a new applet window.
This combination launches three windows: the original browser window (i.e. Discoverer Connections page), the new browser window containing the Discoverer image, and the JFrame window containing the Discoverer Plus applet.
pluspopup=false and framedisplaystyle=embedded launches Discoverer Plus in the current browser window.
See if those help you out, if not let me know and we can dig into this further

Impossible to export more the 1000000 rows With ORACLE DISCOVERER plus

I work with Oracle discorcerer Plus but I'm able to exporte less than 1000000 rows.
more than 1000000 rows he does trunc the result!
I went to the Option as follows:
P.S un-ticked the Tools > Options > Query Governor > Limit retrived data to' field to get all the rows
but it still limits to 999999 records!
Is there any setting to control the number of rows exported ?
Your Help

Hi
The maximum number of rows of data allowed in a query is controlled in three places:
1. In Plus, using Tools | Options | Query Governor
2. In the Admin tool, using Tools | Privileges | Query Governor
3. In the pref.txt file there is a setting called RowFetchLimit
As an end user you won't have teh ability to override what the administrator has set for you so please check to see whether any restrictions are in place that are outside your control.
Best wishes

Can we create a analyses with measures as rows for comparision trend

I am working in OBIEE 11g.
Need to create a analyses with measures as rows and study their yearly progress in a single table
normally dimesions are used as rows and measures as columns but this one is slightly different ..tried using table and pivot but unable to show diff measures in single table
Something like this:
------------------------------------Yearly ------Prev year------change%
Shipped Qty ---------------------150----------100--------------50%
Delivered Qty---------------------150----------100--------------50%
Undelivered Qty-----------------150----------100--------------50%
Billed Qty---------------------------150----------100--------------50%
where shipped Qty , Delivered Qty , Billed Qty are the various measures
Please share your expertise in achieveing this
Would appreciate your help as its urgent
Regards
Pranati

Hi Pranati,
Create a Union report. You have one calculated column with just the text, eg.; 'Shipped Qty' and 3 columns with the 'Shipped Qty'-measures; Yearly ------Prev year------change%
Do the same for the other 3 Qty's
Good Luck,
Daan Bakboord

Customising Discover plus for olap UI

Hi all,
I'm using Discover Plus with an OLAP data source and would like to customise the interface such that:
- The Query Pane window is switched on by default
- When creating a new report the "crosstab" radio button is highlighted by default (usually it's the crosstab and graph)
I realise that these are easy to change in the user interface itself, but I'd like to set their initial status when Discoverer starts - we're going to be rolling this out to around 500 users soon and these small changes will make life easier for everyone.
I suspect the answer lies in modifying one of the middle tier files, but having looked in pref.txt I can find nothing which relates to my requirements.
Any help much appreciated.
Thanks,
Mark...

Look for it in:
http://acidweb.ts.infn.it/oradoc/ias902/bi.902/a95458/conf_fil.htm#635592
There's a list of Discoverer configuration files. Hope this helps.

Result Analysis with transaction code KKAJ for Top level WBS element

Hi Experts,
we have four level WBS structure with level 1 and level 4 with all operative indicators active
when we are doing Result analysis by using KKAJ for level 1 WBS element, System is taking all level 4 wbs elements also into consideration.
Is there a way to run results analysis using KKAJ only for level 1 wbs elements for multiple projects, avoiding the level 4 WBS elements.
SAP version 4.6C
Please suggest.
Thanks in advance

Discoverer BI for OLAP "read-only" privilege problem

Hello!
I set the user privilege to "read-only" but still it allows me to save and edit the report within the user. I'm expecting to read only the report and not to modify it.
Please let me do know if you have a solution for this.
Grace

I think Shared is only for viewing. Try giving full control on main folder( folder which has old reports) in users to the new user.
thanks

Discoverer Plus desktop

I want to download Discoverer Plus to work with Oracle 10g but I can not find it on the Oracle website - what is the url to download Oracle Discoverer PLus client.
Ive built cubes and they work fine with AWM ( i can see the data etc ) but do not work with 10iAS Discoverer Plus so hopign they work with Discoverer PLus client.

Which 10g AS version is this? Discoverer Plus is not downloadable in that sense. You install and run Plus as an applet from Oracle AS instance (accessed via url e.g. http://server:port/discoverer/plus).
Maybe you are looking for Oracle Business Intelligence Discoverer (Plus) for OLAP, which is part of the AS 10.1.2 suite. (do you have an older "10g" version?)
DS 10.1.2 downloads has a BI Tools CD, including Discoverer Desktop Edition (this is what the "thick" client is called). dont know if it handles cubes. Desktop also comes in a standalone install, if you dont need the whole dev tools suite.

Any setup reqd for Disco for OLAP to attach multiple AWs per schema...

I have a schema with two AWs - A, B (created the new AW - B recently). 
When i log on to Discoverer Plus for OLAP via an App Server (givign the schema user/pass), i do not get to pick the AW B explicitly. 
All Measure folders/cubes from both AWs A and B are displayed and i can choose the cube from AW B. However after all the worksheet creation steps are done, the worksheet query fails with the error -- 
======================================== 
oracle.dss.dataSource.common.OLAPException: null 
java.lang.NullPointerException 
java.lang.NullPointerException 
oracle.dss.dataSource.common.QueryRuntimeException: BIB-9009 Oracle OLAP could not create cursor. 
 
======================================== 
D4O Diagnostic test gives the following: 
 
oracle.dss.d4o.common.D4OException: BIB-9009 Oracle OLAP could not create cursor. 
oracle.express.ExpressServerExceptionError class: OLAPI
Server error descriptions: 
DPR: Unable to execute the query, Generic at TxsOqCursorManager::fetchInitialBlocks 
OES: ORA-34224: Analytic workspace <<schema>>.<<AW_B>> is not attached. 
, Generic at TxsRdbResultSet:absolute() 
 
======================================== 
The dimension selections etc (intermediate steps of the wizard) are working on the right data/hierarchies.. So the second AW did get attached. 
If i create a worksheet based on cubes present in AW #1: A, then it works fine. 
Is there any special settings/program... ONATTACH, AUTOGO kind... which is required while using multiple AWs within a schema? 
The schema has olap_user and olap_dba roles as well as access to the Discoverer Catalog via iAS Discoverer Admin. 
Thanks in advance for any help.

Trying to make it readable... Didn't retain line breaks. Now it does. 

Discoverer for OLAP should see all measures and dimensions that you have access to. You never need to explicitly attach an AW.
You are correct in thinking that the AW did get attached if you get to a point in the Workbook Wizard where data is displayed. The error messages are not meaningful to mean. I would guess that it is the result of some sort of metadata error. You might see if AW 'A' is causing any sort of confict by revoking SELECT on AW$A (you'll need to do this as a different user than the owner of the AW) an then attempting to view AW 'B'.
