Discoverer and analytic workspaces

I have an analytic workspace. I would like to access data with discoverer, and I have created a business area with the relational views of the analytic workspace. I have a hierarchy date-month, and in my analytic workspace the date is calculated for both levels. My question is if discoveres is able to access data at month level without recalculating the data. In bi beans the data is not recalculated with an aggregation, but I don`t know if it is the same with discoverer.
Thanks
Laura

Hi Laura,
you have to register a summary table (view) within Discoverer, so Discoverer could use it, istead of aggregating the data again.
Hope this helps.... The AWM which will come sometime, will help you to create such summary views, which is a lot of manual work without a program.
Best Regards,
Heiko

MV vs. Analytic workspace

Good morning,
I read the document http://www.oracle.com/technology/products/bi/db/11g/pdf/comparision_aw_mv_11g_twp.pdf
and I not understand clearly the difference, this probably made due to a poor knowledge of English.
Someone just enlighten me?
AW generates views for the cubes and dimensions, allowing a SQL query, the MV too.
The MV directly contain any aggregates but it is also possible with cubes (you can define a level of aggregation total).
My assertions are they correct?
So what are the major differences between the MV and analytic workspace Oracle?
Thank you once again in advance,
David

The data for an 11g cube is stored in an AW. This includes both leaf and aggregate data.
This data in a cube can be accessed directly by an automatically generated SQL View. (This is sometimes called an 'ET View'.)
Optionally, the system can also generate an MV on top of the cube. This MV should be thought of as pure metadata on top of the cube -- the MV itself does not contain any data. The closest analogy is the
CREATE MATERIALIZED VIEW ON PREBUILT TABLE
statement. The MV defined on top of the cube provides a number of things.
(1) You can access the data directly by running SELECT * FROM <cube mv>. This is possible, but gives you nothing that you could not get by selecting from the ET View instead.
(2) It ties the cube back to the source tables so that the system will know if the data in the cube (i.e. the AW) is FRESH or STALE.
(3) It allows you to optimize the build of the cube by using FAST MV refresh if you change only a few rows in your fact table.
(4) It allows the system to rewrite queries against the source tables to access the cube directly.

Cannot able to delete the Analytical Workspace and its objects.

Hi,
My Analytical workspace (11.2.0.2 B) seems to be corrupted. I could not able to attach the workspace through AWM and i cannot even able to delete it. I found there is no other session attached the Work space. I used the below query to find the locks on the work space.

Hi,
When i try to execute your statement through Toad, i am getting the below error.

What is the problem ? What more should I install ?
Many thanks for your help.

Hi,
What more should I install ?Did you do the OLAP catalog (dbms_olap)?

Analytic Workspaces and Database Tablespace

Hi,
I am trying to understand the intricacies in the setup of Analytic Workspaces and their corresponding tablespaces in the database, and here is the background:
I created an Analytic Workspace, say AW1 in a database that had a tablespace, say TS1. After sometime, I created another Tablespace, TS2 in the same database and using the same schema as before, created an Analytic Workspace, AW2 in TS2.
However, AW2 seems to get created in TS1 even though I select TS2 explicitly at the time of creating AW2. Also, if I drop an AW created using TS2 and then import it again (in the same schema) from the template, it gets created in TS1 and not TS2 as I would expect.
In essence, it seems to me that all AWs get created in the TS that was the first TS of my database (TS1 in this case), irrespective of the fact that I created them in different Tablespaces. Also, for all these experiments, the database and the environment is the same.
Can anyone please explain this behavior?
For reference, the database in use is Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bit Production With the Partitioning, Oracle Label Security, OLAP and Data Mining Scoring Engine options
and the AWs have been created using Oracle Analytic Workspace Manager (AWM) v10.2.0.3.0A.
Any help is much appreciated.
Thanks and Regards,
Piyush

Hi Piyush,
AWM lets you specify the tablespace for your AW which allows you to override the default tablespace for the user. However, this information is not recorded in the XML template. Therefore, if you create an AW in a non-default tablespace, save the definition to an XML template, drop the AW and use the XML template to rebuild the AW then the AW will get created in the default tablespace.
There are two workarounds to this (that I can think of)
1) Use a script to rebuild the AW from the XML template and alter the users default tablespace as part of the script and then set it back after the AW has been built.
2) Use the AW Create packages that do allow you to specify the tablespace for the AW, run the DML command to create the standard form metadata and then script the loading of the XML definitions for each dimension and all your cubes.
Hope this helps

ETL with OWB and Workspace Manager with Analytic Workspace Manager?

I already created my dimensions and cubes with "warehouse builder", as a tables, so can I map them in the dimensions and cubes defined with "analytic workspace manager?
please somone help, becasue I can't found this information on a manual "OLAP application's developers guide".
also, whichis the manual that I have to follow to create things in AWM? i think is this that I use "OLAP application's developers guide"
Someone can tell me something?
Thanks.

Hi,
I.m using OWB 10.1.0.4.0 and choosing "Project" then "Metadata Export" and finally "Bridge" I can lanch a wizard that allow me to choose between 3 kind of export.
If you choose OLAP the wizard will ask you which collection of metadata to export and other options, after succesfully running this wizard (which is not so easy) you can open the AWM and see the export of your dimesion and cube iside an AW.
I'm finding lots of problems using this feature due to the limited options I can set to the cube and the dimension (type of aggregations, calculated measures, limit on the number of measures in the cube, etc.).
Waiting for the new OWB Paris if you can post your experience it will be very appreciated.
Good luck,
Franco

Oracle Express(Analytical workspace?) and Oracle warehousebuilder

Can somebody please explain when and why to use
Oracle Express(Analytical workspace?) and Oracle warehousebuilder.
When should each of these tools be used?

Oracle Express is an old, de-supported product that has been replaced by Oracle Database OLAP Server http://otn.oracle.com/products/bi/olap/olap.html.
Oracle Warehouse Builder (OWB) is a data integration design and management tool. One of OWB's areas of functionality is enabling OLAP. All OWB OLAP related materials are summarized and linked from OWB Self-service Education page here http://otn.oracle.com/products/warehouse/selfserv_edu/OLAP_cube_creation.html

Analytic Workspace Manager 11.2.0.3.0a and Oracle11g 11.2.0.4

Hello!
I'm trying to connect from Analytic Workspace Manager, version 11.2.0.3.0a (latest one), to Oracle server ver. 11.2.0.4. Connection fails with following message "This version of Analytic Workspace Manager is incompatible with the database instance.". Is there a way to make this work? The solution I'm aware of is to downgrade a server. Maybe someone knows other solutions?

There are posts on the OLAP forum covering this problem. Anthony Waite from the OLAP Product Management team has provided the following information:
e new, default Model View in AWM 10.1.0.4.0 is based upon the OLAP Analytic Workspace API (a.k.a. AW/XML). Just to recap and further clarify my earlier post, you must pass the following requirements in order to use it:
1) Be sure to be using the Enterprise Edition of the Oracle Database 10g.
SQL> select banner from v$version where banner like 'Oracle%';
You should see Oracle Database 10g Enterprise Edition.
2) Be sure to have the Data Warehouse database configuration or the OLAP Option enabled.
SQL> select parameter, value from v$option where parameter='OLAP';
You should see OLAP TRUE.
3) Be sure that the RDBMS 10.1.0.4 patch set has been completely installed. Users often miss the required Post-Installation Steps such as running catpatch.sql.
SQL> select comp_name, version, status from dba_registry;
You should see VALID and 10.1.0.4.0 for the OLAP components.
4) The Oracle Database must have the compatibility mode of 10.1 to use the Model View as it relies on the unique features found in Oracle Database 10g.
SQL> select name, value, description from v$parameter where name ='compatible';
You should see 10.1, not 9.2 or earlier.
5) Please refer to the patchnote.htm that is bundled with 10.1.0.4.0 patch set. Only you are aware of what type of database configuration you have. You will want to pay close attention to "7.2.1.3 Set the SHARED_POOL_SIZE and JAVA_POOL_SIZE Initialization Parameters" and "7.2.2 Upgrade the Release 10.1 Database".
Basically, I believe you have missed these required steps after installing the 10.1.0.4.0 patch set from the OUI: (pasted from the patchnote.htm)

Analytic Workspace Manager - Hierarchies within hierarchies

Hi,
We have six levels of Sales Groups (SG) and two levels of Sales Personnel (SP).
- SG1
SP1- Sales Manager
SP2- Sales Rep
- SG2
SP1
SP2
- SG3 ... so on and so forth
We want to have drill down capability on SG1 so that we see SP levels underneath followed by the next level Sales Group i.e. SG2.
My question is can we have hierarchies within hierarchies using Analytic Workspace Manager and can this be queried using Discoverer Plus for OLAP. If there is another way to do it, can someone please explain?
Thanks again,
-Esther

I am not totally sure what you are trying to achieve as I think you might be confusing members with levels. From an OLAP perspective we support two basic types of hierarchies
- Level based
- Value based (Parent-Child)
Within level based we additionally support:
- normal
- ragged
- skip level
Normal implies that you have a hierarchy where the each member for each level always has a parent at a the next level up in the hierarchy. Ragged hierarchies are where data is loaded at different levels within the hierarchy and skip level is where parents within a specific level are themselves defined at multiple levels.
I am not sure if this answers your question, but you can find more information on how to manage hierarchies in the
Oracle® OLAP Application Developer's Guide

Is it possible to create relational view on Analytic Workspace in Oracle 9i Release1

Hi All,
We are in the initial stages of Oracle 9i OLAP prototype. Since the current version of BIBeans 2.5 does not work with Release 2 of Oracle 9i OLAP, we are planning to use Oracle 9i OLAP Release 1. So can you please answer the following questions.
1. Is it possible to create relational view on Analytic Workspace(like in Release 2) and populate the OLAP catalog, if so can you give me guidance to get the appropriate user guide. The OLAP DML guide in Release 1 talks about creating OLAP catalog metadata for Analytic Workspace using a metadata locator object.
2, Is it advisable to use Oralce 9i OLAP Release 1? Does the Analytic Workspace and the corresponding BIBeans work in Release 1?
Thank you,
Senthil

Analytic Workspaces (Express/multidimensional data objects and procedures written in
the OLAP DML) are new to Oracle9i OLAP Release 2, you cannot find them in Release 1.
BI Beans will soon (within a week) introduce a version on OTN that will work with Oracle9i OLAP Release 2.

How to install analytic workspace manager?

I have Oracle 9.2.0.1 running on Windows. I have installed 9.2.0.3 database patch. I couldn’t see analytic workspace manager tool? How to get the tool?
I will greatly appreciate if you can guide me with some links or steps.

Few days back I went to a Oracle Demo and there I used Analytic Workspace Manager, which is running on Windows 2000 (both database and the tool on same machine).
It was located in
Start menu --> Oracle home --> Integrated Management Tolls Folder.
I couldn't see that on my 9.2.0.1 installation. So I installed the new patch 9.2.0.3, still I am not able to see that tool.
Am I missing anything? Any other patch?

19.     Review the patch.log file for errors and inspect the list of components that is displayed at the end of catpatch.sql script.
This list provides the version and status of each SERVER component in the database.
20.     If necessary, rerun the catpatch.sql script after correcting any problems.
21.     Restart the database:
