Analytic Workspace enablement for Discoverer failed

Happy New Year All.
I created the AW using AWM 9.2.0.4.1D.
While I was tring to enable the AW for discoverer I got the following error message..
The following error occurred while exporting to Discoverer.
dataprovider error initializing the AW
Did anybody get the simillar message.. do you know what might be wrong?

This could be caused by picking up the wrong oraolapi9 library. If you can't readily reconcile the library versions, please open a TAR.

AWM error when enabling for discoverer.

Hi,
I am experiencing some difficulties enabling my analytic workspace for discoverer. I have a created a workspace based on a cube with 1 fact and 2 dimensions. I used Oracle Enterprise Manager 9.2.0.1.0 to create my meta data and AWM 9.2.0.4.1D to create the workspace. When I enable for discoverer plus in AWM it takes me through the wizard and at the end when I click on finish, I get an absolutely non descriptive error...it is: "dataprovider error initializing the AW". I go to the awmrun.log file to see what happened, and it is also confusing. There is a SQLException underneath, but it doesn't say what the overflow was on:
Error java.sql.SQLException: Overflow Exception

i have made a little more progress with this.
i am not having any problems with users that are created via exchange using New-Mailbox
it is only user accounts that have been enabled for exchange that are causing problems via Enable-Mailbox.
Both user accounts are in the Same OU, have same UM Dial Plan.
i have run a compare of security permissions using dcacls and there is a difference. mainly on an attribute called Group.
i have checked the security permissions and group membership and can't see it listed anywhere. please see output below:
compare-object $broken $working
InputObject SideIndicator
Group: XX\Domain Computers =>
Inherited to inetOrgPerson =>
Inherited to computer =>
Inherited to inetOrgPerson =>
Inherited to group =>
Inherited to contact =>

any idea how when enabling a mailbox exchange can ensure it has the correct permissions on it?

Where to find Analytic Workspace Manager for Oracle9i?

Hi,
I am looking for Analytic Workspace Manager for Oracle 9i. Could someone point me to the place it can be downloaded? On Oracle OTN there are only versions 10g and 11g. I couldn't find it on Metalink either.
Why I need so old version? We are about to upgrade our existing installation from 9i and I need it to see what's inside in our Oracle 9i database (9.2.0.6) before going into 10g.
Or maybe it is possible to use AWM 10g against database 9i? This would solve my problems.
Is it possible to upgrade analytic workspaces from oracle 9i into 10g with analytic workspace manager 10g?
Best wishes
Tomasz Michniewski

Hello Laura,
Well, I was looking for this 9i version of AWM, and I was even thinking that AWM does not exist for 9i. Especially that in 9i documentation AWM is not mentioned.
But in the meantime I have found some install from some our backup cd-rom. It says:
# Analytic Workspace Manager : 9.2.0.4.1
# DATE: September 26, 2003
# Platform Patch for : platform independent
# Product Version # : 9.2.0.4.1
# Product : Analytic Workspace Manager
# Platforms
# Analytic Workspace Manager uses a platform independent install and
# has been approved on the following platforms:
# - Windows NT 4.0, 2000 & XP
# - Solaris 32 & 64-bit
# - Linux 32-bit
# - AIX 64-bit
# - HP-UX 64-bit
# - Tru64
# Requirements
# The Analytic Workspace Manager client requires the following Oracle9i
# Database configuration:
# - Oracle 9.2.0.1.0 Enterprise Edition Database
# - RDBMS 9.2.0.4.0 patch set (PS# 3095277)
# - OLAP 9.2.0.4.1 patch (PS# 3084634)
So is it the AWM for 9i?
Best wishes,

Are Analytic Workspaces suitable for very large data sets?

Hi all,
I have made many different tests with analytic workspaces and i have used the different features (compression,composites...). The results especially for maintenance are disappointing.
I have a star schema with 6 dimensions. The fact table has 730 million rows, the first dimension has 2,9 million rows and the other 5 dimensions have between 25 and 300 rows each.
My conclusion is that Analytic Workspaces don't help in situations like mine. The time for maintenance is very very bad not to mention the time for aggregations. I even tried to populate the cube in parts( 90 million rows for the first population) but nothing change. And there are some other problems with storage and tablespaces ( I always get the message unable to extent TEMP tablespace. The size of it is 54Gb).
Is there something i missing? Has anyone similar problem or different opinion?
Thank you,
Ilias

A few other tips to add to Keith's excellent advice:
- How many CPU's does your server have? The answer to this may help you decide the optimal level to partition at (in my experience DAY is too low and can cause different problems). What other levels does your time dimension have? Are you loading your cubes in parallel?
- To speed up your load, partition your underlying fact table with the same granularity as your cubes and place an index on the field mapped to the partition dimension
- Are you using 10.2.0.3? If so, be very careful with the storage data type you choose when creating your cubes. The default in 10.2.0.3 is NUMBER which has the capability of storing data to 38 significant figures. This usually exceeds what is required for most datasets. If your dataset allows you to use storage of 15 significant figures then you should create your cubes using the DECIMAL data type instead. This will use about one third of the storage space and significantly increase your build speeds (in my experience, more than 3 times faster)
- Make sure you have preallocated enough permanent and temporary tablespaces for your build. Autoextending can be very time consuming.
- Consider reducing the amount of aggregation you do in batch. It should not be necessary to pre-aggregate everything in order to get good query performance.
Generally, I would say that the volume should not be a problem. A single dimension with 2.9 million values is fairly big and can be slow (in OLAP terms) to query but that should not be an obstacle to building it in the first place.
Good luck!

Where can i find the analytic workspace manager for 11g

Guys,
I just downloaded the win32_11gR1_database_1013 from the website, however i did not find the 'analytic workspace manager' component as what the document mentioned during the installation.
Anybody can help me on this?

however i did not find the 'analytic workspace manager' component as what the document mentioned during the installation.Could you point us to that documentation?

Measure folders in analytical workspaces

Hi,
I was wondering how I should create measure folders for analytical workspaces. For rolap measures I can use the CWM2 package to do this, but this doesn't work for molap measures. I know I can use AWM to create folders, but only at one level. I want to create folders with parents. In the view ALL$OLAP2_AW_CATALOGS in the OLAPSYS schema there is a column named PARENT_CATALOG_NAME, so based on this I believe its possible.
Does anyone know the OLAP DML commands to this? or any other way of doing this?
And one more thing, is there any other documentation on OLAP DML other than the Oracle OLAP DML reference(10.2) ?
regards Ragnar

This is an issue we are looking to resolve with a future release of BI Beans. This will assume a user has the role of OLAP_USER assigned, at which point only a user will only see measure folders to which they have access.
Hope this helps

AWM: Enable Analytic Workspace for OLAP API

Hi,
I created an analytic workspace with Analytic Workspace Manager which is based on a relational star-schema.
Now I want to access this analytical workspace by normal SQL-Statements. For this I executed in AWM the 'Enable Analytic Workspace for OLAP API and BI Beans ...' routine which generated views that contain the fact and dimension data.
My problem is that these views are very huge, because they
apparently store all possible combintations of dimension- and fact records. Most of the records contain only NULL values in the fact columns. I also used Composite Dimensions for the fact table in order to reduce sparsity.
Is it normal to have such huge views with mostly NULL values? If yes, how can I handle this in order to get an acceptable performance.
Here an example of a small fact table I use:
A fact table with 5400 records with its two dimension tables (1129 and 233 rows, no hierarchies) produces 263057 rows in the view.
Thanks for any help.

Hi,
First of all, thanks for the quick response flavio.
Meanwhile I have found a solution to my problem:
I don't use the 'Enable Analytic Workspace for OLAP API and BI Beans ...' routine of AWM anymore. Instead, I write my own statement for creating a relational view for the analytical workspace. The statement looks like following:
create or replace force view costrate_cube as
SELECT producttype_number, producttype_description, machine_sk, notok_costrate, production_costrate
FROM TABLE(CAST(OLAP_TABLE(
'costrate_aw DURATION SESSION',
'costrate_table',
'FETCH producttype_dim_producttype_number,
producttype_dim_producttype_description,
produnit_dim_machine_sk, produnit_dim_module_sk,
notok_costrate_variable, production_costrate_variable
USING <costrate_cube_composite>','') as costrate_table));
The important part is the USING clause of the FETCH command. By using the composite of all dimensions of the cube, rows containing only null values in the fact columns are being eliminated. Now I get only the rows which are in my original relational fact table (which is what I wanted).

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

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)

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?

Analytic Workspace Manager

Hi
I am completely new to Oracle OLAP.
I have installed Oracle 10g(10.1.0.2) with OLAP option enabled.
I would like to create some cubes using Analytic Workspace manager. When I look into Oracle HomeIntegrated Management Tools, I wouldn’t find Analytic Workspace manager.
Do I need to install Analytic Workspace manager separately? If it comes along with the oracle suite, what did I want to do to have analytic workspace manager in my machine?
Please help me.
Thanks,
Deepa

Hi
Thanks for the info.
I like to get more information regarding the same in version 10.1.0.2

Creating Database Standard Form Analytic Workspaces

Just been looking through the new 9.2.0.4.1 documentation and came across the following. Thought it might be useful.
The 9.2.0.4.1 release of Oracle OLAP introduces a new concept known as �Database Standard Form� Analytic Workspaces. This is a way of constructing analytic workspaces in a standard way such that they can be used by tools such as the Analytic Workspace Manager, the Java OLAP API, and BI Beans.
When analytic workspaces are created from a relational star-schema using the Analytic Workspace Manager, it automatically creates the analytic workspace in standard form as part of the migration process. However, if you�re migrating an Express database to Oracle OLAP, the migrated database has to be processed to be in standard form before it is usable by any of the new Oracle OLAP GUI tools.
If you create an analytic workspace using PL/SQL or the OLAP Worksheet, of course you can create dimensions, variables, relations and so on in any form, just as you can create table structures, joins, views and columns in any form in a relational database. However, the database standard form requirement stipulates that;
Certain objects and properties need to be found in the analytic workspace, that are used by tools such as the Analytic Workspace Manager to perform tasks such as aggregation, data loads, and OLAP API enablement. OLAP DML views (beginning with AW$) need to created in the analytic workspace, to provide metadata and to identify relationships between objects in the analytic workspace. Objects need to be registered in the OLAP Catalog, and these registrations have to be kept in sync so that the OLAP tools are aware of changes to the base objects. Data that is migrated in to an analytic workspace, from a relational star-schema using the Analytic Workspace Manager, is already in database standard form and no further work is needed. However, some work is needed to get migrated Express databases into standard form, and Oracle have provided a utility with the 9.2.0.4.1 release of Oracle OLAP to help accomplish this.
This utility, known as CREATE_DB_STDFORM, is an OLAP DML program that takes existing Oracle Express Objects metadata in a migrated Express database, and uses this to create the additional metadata required to make the analytic workspace �database standard form�.
Once CREATE_DB_STDFORM has been used to create this additional metadata, it can also be used to import data into the workspace either from flat files, or from Oracle tables and views. If you don�t have Express Objects metadata in the Express database, CREATE_DB_STDFORM doesn�t work, and you�ll have to use Oracle Warehouse Builder 9.2 to initially create a relational star-schema that equates to the Express database, then use the OLAP Bridge within OWB to export the data into a database standard form analytic workspace.
CREATE_DB_STDFORM, once run, allows the migrated Express database to be accessed via BI Beans straight afterwards, as it creates all the OLAP Catalog entries required for the OLAP API. If the Express database only contains data at the lowest level (i.e. it hasn�t been rolled up), aggregation wizards in the Analytic Workspace Manager can be used to summarise the data as required.
CREATE_DB_STDFORM doesn�t do everything, however. First of all, you need to have created Oracle Express Objects metadata within the Express database, which is an additional step and not always appropriate for all systems. In addition, you need to create time dimensions in a particular way, which may require the data model to be adjusted to meet this requirement. Lastly, any Express language programs within the Express database may need to be adjusted to remove or change commands that have changed or become obsolete.
The new document, �Oracle OLAP Application Developers Guide Release 9.2.0.4.1�, available on metalink under note 251352.1, details how database standard form works, has code examples, and walks through the migration of the XADEMO Express database to an analytic workspace using database standard form.

In your message, you wrote "Certain objects and properties need to be found ... aware of changes to base objects". A large bit is represented by "...". Question is whether I have any commands or package functions that I can use to set up all the proper objects and relationships to make it have database standard form, short of regressing to a ROLAP star schema and usnig the AWM wizard. I have what appears to be working MOLAP activity, all created at the OLAP worksheet prompt, and loaded with DML program. Do I really have to put that all aside and start with a star schema? No way to put my AW in standard form for OLAP API without this?

Analytic workspace version error

I am running 10g on WinXP. I am using AWM 10.1.0.4
I connect to the db and am able to view my schemas.
When I attempt to create a Workspace in "Model View" I recieve the error
"ORA-00904: "O"."SF_VERSION": invalid identifier"
Do I need an earlier version of AWM?
Thanks in Advance

It appears you might have an issue with 'C' below. Here is a checklist to make sure your Oracle Database is properly configured to run with Analytic Workspace Manager 10.1.0.4:
A) Make sure you have the Enterprise Edition of the Oracle Database 10g.
SQL> select banner from v$version where banner like 'Oracle%';
You should see Oracle Database 10g Enterprise Edition.
B) Make sure you have the Data Warehouse database configuration or the OLAP Option enabled.
SQL> select parameter, value from v$option where parameter='OLAP';
You should see OLAP TRUE.
C) Make sure 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.
D) The Oracle Database must have the compatibility mode of 10.1 to use the new Model View in Analytic Workspace Manager 10.1.0.4.0 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.

Refresh Analytic Workspace increase tablespace size ?

Hello, I'm using CWM2 OLAP objects with 9.2.0.6 database version. I have analytic workspaces, too.
I execute refresh of my analytic workspace, using the script generated by Analytic Workspace Manager 9.2.0.4.1. I have noticed that, strangely, whenever I execute the script, it increases the used space of the tablespace containing analytic workspace.
Is this usual ? The script doesn't include new objects, and the effect is the same. What is failing ? I think that this should not happen.
Any idea ? Thanks a lot by your help

vbarres wrote:

difficult to reserve space on disk for this...I'm confused here. Are you really adding new objects every day, or just adding more data to the existing ones. In general, if you are adding more data, the growth should be reasonably predictable, assuming a reasonable AW design. The usual growth confusion has to do with reloading the same data over again, where the growth is unexpected.

In my case I had made several cubes to perform different tests. When I deleted all but >one cube things behaved more normal and the aggregation time was stable.Again, I'm not sure what is going on here from the descriptions. As far as I know, there should not be a problem with multiple cubes in the same AW. You don't say what version you are in, but is it possibly version 10? I could see some interaction in a parallel build, where the various cubes are built simultaneously, and thus the pages on the free list are necessarily available for reuse when you might want them. More details would be interesting here. You might also try a serial build (I'm not sure where the switch is in AWM, but I'm sure it's there somewhere).
