Building OLAP 11g Cubes Tutorial

I followed the tutorial [http://www.oracle.com/technetwork/database/options/olap/buildicubes-090657.html#o]
all the way to the section of Mapping cubes to relational sources and I got stuck. Since the images / diagrams do not come up I was unable to figure it out, can somebody assist me on this matter. Maybe there is a way to be able to view the images / diagrams. I am very new to this cubes and so far I find it very interesting, but I still want to understand fully the advantages of using cubes in reporting in OBIEE.

Thanks

Not sure why the images are not showing up on this website. Maybe someone from development can get it fixed.
Regarding benefits of using OLAP cubes with OBIEE, see recent posts:
HOLAP - using OBIEE and Oracle OLAP
and
Usage of OLAP
There are lot of benefits. It simplifies reporting, as the calculations and aggregations are "pushed" inside the database (i.e., OLAP cubes).
No need to create MVs or aggregate tables.
Adhoc Query performance is excellent, no matter what level of data you are looking at.
Calculations are very easy to create, and automatically works at all levels of all dimensions.
OBIEE rpd work is extremely simple, and very minimal - compared to obiee reporting from relational sources.

Error while maintaing olap 11g cube

Hi,
Iam getting the below error while trying to maintain the cube
An error has occurred on the server
Error class: Express Failure
Server error descriptions:
INI: Error creating a definition manager, Generic at TxsOqConnection::generic<BuildProcess>
INI: XOQ-01724: Can not specify a USING clause with a rewrite MV cube, Generic at TxsOqBuildProcessor::initializeForDimension

ALso when I try to drop the cube/dimension , I get the following error
An error has occurred on the server
Error class: Express Failure
Server error descriptions:
DPR: Unable to create server cursor, Generic at TxsOqDefinitionManager::generic<CommitRoot>
INI: XOQ-00703: Error executing OLAP DML command "(AW ATTACH CBU_UNIFIED.RECHARGES RW : ORA-34738: A severe problem has been detected. Analytic workspace operations have been disabled.
)", Generic at TxsOqAWManager::executeCommand

The two errors are, I suspect, unrelated.
The XOQ-01724 error happens if you attempt to execute dbms_cube with a script that contains a USING clause. This is allowed for most cubes, but not for cubes associated with a materialized view. If this is what you tried to do, then the error is expected and the solution is to not specify a USING clause or to drop the MV.
The second error is much more serious since it means your AW is probably corrupted. Did this happen after a failed parallel build? What version are you using.

Accessing OLAP 11g Cubes

Hi Experts,
We are on OLAP 11.2.0.1 and have built cubes using AWM 11g. What are the different and best ways to provide access to these OLAP cubes for reporting. We are looking at Simba MDX provder. Any idea if XML Publisher can be used to provide access to these cubes? If so, Can you please let me know from where can i get any information/documentation related to this? We would ideally want to study the pros and cons b/w the various ways of access 11g OLAP cubes.
Look forward to suitable replies.Thanks in advance.

You can refer to this page here => http://www.oracle.com/technetwork/database/options/olap/index.html
You also have APEX to query the olap cubes other than excel addin from simba and OBIEE.
Thanks,
Brijesh

OLAP 11g BUILD CLEAR example

Can anyone please help me find the syntax/plsql block of clearing dimension data from cube in OLAP 11g?
Thanks

BEGIN
DBMS_CUBE.BUILD('OLAPTRAIN.CHANNEL USING (CLEAR)');
END;
Note that when you clear a dimension, you also clear data from every cube that is dimensioned by that dimension.

Is the SQL Server and Analysis Server are running on different servers and not on default ports?
If yes, then check if the same alias’s name added in Project Server is added on the Analysis Server.

Export OLAP 11G AW/Cubes to OBIEE 11g

Hi Experts,
If anyone has handled this assignment of exporting OLAP 11G AW/Cubes to OBIEE 11g, Please share all details. Currently we use BO for reporting requirements and before going ahead with OBIEE 11g would like to make sure there is not much of a gap. As of now we see a lot of incompatibility while exporting like some dims and cubes cannot be exported and so on. Any white paper/docs/information on this from experienced folks are welcome.
We are on 11.2.0.3 db release.
Thanks in advance,
MS

Here is some basic information about importing 11g analytic workspace cube and dimension metadata into OBIEE.
There are two basic options as I suspect you already know:
Option 1) Before the release of OBIEE 11.1.1.5 (I believe), there was no native support for the OLAP option within the administrator tool of OBIEE, and
one needed to use the AwM plug-in to OBIEE. The AwM plug-in generates a UDML file which can be imported into OBIEE using the OBIEE admin tool.
The AwM plug-in to OBIEE generates metadata for the source, business model, and presentation layers. The very latest version of the AwM plug-in will specially
handle calculated measures created in AwM and create the proper calculcated measure expression in OBIEE. This is very important if you are querying above the cube
to get the correct aggregation results. One area that has limited support is if a dimension only has value-based hierarchies. The plug-in will create a very simple level-based
hierarchy to at least allow the dimension to be successfully created. You then need to do more work within the OBIEE administration tool to create the fully baked
value-based hierarchies. I do not have any real-world experience with value-based hierarchies in OBIEE. Again, the AwM plug-in to OBIEE works with level-based hierarchies
and supports multiple hierarchies per dimension. The AwM plug-in to OBIEE is available on the OTN download page for the OLAP option.
Here is the link: Oracle OLAP Downloads: Software & Samples
Option 2) OBIEE 11.1.1.5 and later allows for native integration for accepting OLAP 11g dimension and cube metadata as a supported source.
This integration makes the AwM plug-in somewhat obsolete (except for the calculated measure expression integration which is unique to the AwM plug-in and using
AwM to create calculated measures including time-based calculated measures)
Please expand on the incompatibility issues you are running into. Is this related to a lot of value-based hierarchies or other issues?

Best practice for building OLAP cubes??

Hi All,
I have to build about 10 cubes as minimum for 50 GB database that share some dimensions, these cubes for 6 business areas.
I want to know whether to build all cubes on one analytical workspace or what??
Regards,
Gado

If the cubes are going to share dimensions, then yes I would recommend putting them all in the same analytic workspace.

11g Cube not showing any data with no Rejected records

Hi David ,
Strangely one of my 11g Cube is not showing data from today as it is showing all records rejected . However when I lookup Rejected records table I didn't find any records .Not sure what is happening . When I want to peep out the AWM queries from CUBE_BUILD_LOG and ran to the database in the AWM schema the records are retruning perfectly fine . I wonder same query is firing during Cube load but without any data ? My Cube build script has only LOAD and Aggregate .
after maintain My dimensions data are looking fine but no data populated after Cube maintenance . My MV switch off across all dimensions and cubes .
I navigate to CUBE_OPERATION_LOG and not able to comprehend about the content.
Any advice ?
Thanks and Regards,
DxP

Hi David ,
To be very frank today is very bad day ... Please see below my observation:
Executed below to make sure that no key values in dimension is missing but present in fact . All below query returns no row.

I dropped the AW and create new from exported XML and maintain all dimensions and then rebuild . Still have the issue :(
Any thing you can hightlight from above ?
Thanks,
DxP
Also I sustpect whethere it is a issue due to below error caused when I click on one of my Position_Hier view from AWM : even if I select that view it is throwing the error in SQL developer after displaying first couple of rows (while page down)
java.sql.SQLException: ORA-33674: Data block size 63 exceeds the maximum size of 60 bytes.

How do I know what is the minimum resource requirement for OLAP 11g?

How do I know for OLAP 11gR1 ...
1. what is the minimum number of CPUs and speed required
2. how much minimum physical memory, SGA, PGA etc. is required?
Regards, Anirban

Hello Anirban,
In summary, since the OLAP option is an option to Oracle Database 11g, Enterprise Edition the minimum requirements in order to run the database would be identical to those necessary to run a "Data Warehousing" type installation. That being said starting up a database is a far cry from actually performing well while accessing and building OLAP Cubes in your Database.
There are lots of things to consider. For example: the complexity of your model; data sparcity; level of aggregation; system load, SLAs, etc..
Lets look at true minimum requirements and then consider what it would take to achieve good performance in your environment
TRUE MINIMUM...
I performed a test in my environment (Oracle Database 11g Release 2 (11.2.0.2.0) on Oracle Enterprise Linux 5.5) using Analytic Workspace Manager 11.2.0.2.0A and found the following minimum settings to work against the OLAPTRAIN schema (You may find it here http://www.oracle.com/technetwork/database/options/olap/index.html). This is a very small schema which we use for demonstration purposes.
I discovered that the database started with a memory_target of only 160m (apparently this is the absolute minimum for my environment). I knew that if the database successfully started that I would be able to query the Cube but maintain it? Running queries against the OLAPTRAIN Sales Cube, despite being slow, worked as anticipated. Next, I performed a maintain operation on the Sales Cube where I had to abort the job because it ran into memory issues at 160m, however, when I increased it to only 180m it did a complete maintain in a reasonable timeframe, albeit slow considering the limited resources.
MINIMUM REQUIREMENTS TO ENSURE REASONABLE PERFORMANCE IN YOUR ENVIRONMENT
Most importantly ensure you have a good cube design
Run a sample set of your data in order to define what "reasonable performance" is for your environment. Create a small representative cube in order to test both build and query performance while collecting and analyzing database statistics through AWR and ADDM. For OLAP option specific queries please take a look at http://wiki.oracle.com/page/OLAP+option+-DBASample+Scripts.
You could creat a view on top of your fact table and use the view to generate your OLAP Cube. This will allow you to test a more manageable amount of data. For example, if you have 10 years of data and want to determine the footprint and resources required in order to manage a Cube of this volume then consider scoping it down to a few months first then increase it by a measured amount in order to predict requirements. Monitor your resources and ensure you balance I/O, memory and processors. Since the OLAP option is a Enterprise Edition option it falls under Data Warehousing. As such there is plenty of literature available on oracle.com in order to define what it takes to achieve a balanced Data Warehouse.
I would recommend contacting Oracle Consulting or an Oracle Partner to determine the best fit for your environment.

Anyone know of a good OLAP DML/DDL tutorial? (and NOT reference guide)

In addition to Analytic Workspace, I am trying to learn how to build cubes using just the OLAP DML / DDL language.
Oracle and others have published a great deal of reference material on the language of OLAP DML / DDL but I can't find any real tutorials that guide me logically thru the process of creating cubes and all that goes with it (defining dimensions, hierarchies, measures, calculations etc..) All the reference material is spread out in bits and pieces and difficult to efficiently learn from. Does anyone have any good OLAP DML / DDL tutorial links they could recommend? Thanks.

Thanks.This is a very difficult task. The OLAP DML/DDL only supports basic multidimensional variables, dimensions (very primitive), and relations. The externally visible cubes and dimensions are a construct of a lot of component objects (a dimension has many primitive dimensions and relations put together to create the higher level DIMENSION that goes with a cube; a cube has multiple variables and other pieces that get put together) in the AW, plus a bunch of metadata objects in the Oracle dictionary.
You really don't want to try to create your own and expect them to interact with the OLAPI interfaces. It is possible to construct your own version of things, but you'd also have to do your own view generation, etc. There are applications out there that are created from scratch, but they are completely from scratch (including whatever interactions they have via SQL). Whatever you create will not work with any of the Oracle-provided interfaces, nor the recently-announced Simba MDX package.

Help on OLAP 10g Cube

Hello Experts ,
Anybody has idea why simple SUM on measure group by dimension on my OLAP 10g cube performing so slow even a simple query taking lot of time and even not returning the result , Is it due to performance cause or due to some design issue or due to DB pramaters which restricting the cube data to be returned ?Is it known issue with database bug . I am on AWm 10g latest with 10g 64 bit DB 10.2.0.4 .
As we are completly stuck and not being able to progress the query on simple cube build on 20K data wiith 7 dimension However we tried with 2 dimension and it works perfectly fine .
any advice ?
Thanks ,
Debashis

Hi David ,
Even we tried to perform a query like :
Select * from mycube_view where measure1 is not null ;
also:
Select distinct measure1 from mycube_view ;
The query is running for ages without any result .
Also I can see 10g style cube views having diff structures like for 10g all the dimensions attributes present in the cube view itself . So for my OBIEE I could use single table based reorting I believe right ? But I wonder for OBIEE I need to put aggregate on my measure attribute or not ! for 11g I had put the aggregation like SUM against the measure attrbt there.
Many Thanks,
DxP

Help with OBIEE reports on Oracle 11g Cube

Hi,
We have created a 4-Dimensional Oracle 11g cube using AWM 11g and have integrated that with the OBIEE repository using the Dimension Hierarchy views as created by AWM.
Now, when we create a “table” type of report with this cube in OBIEE Answers, all goes fine – we can see all the expected data in the report. However, if we create a “pivot table” type of report using the same selection (query) criteria as in the “table” type of report, then all the cells corresponding to the measure columns show up as blank (empty) – no data is populated in the measure cells. This happens regardless of the positioning of the 4 dimensions in the pivot table - columns, sections, and pages.
Are we missing something in the repository/report setup here? Any help is much appreciated.
Thanks and Regards,
Piyush
Our Environment:
Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
AWM v11.1.0.6.0A
Cube Type: OLAP 11g
Oracle Business Intelligence Enterprise Edition 10.1.3.3.2
Any help on this thread is much appreciated.
Thanks,
Piyush

Hi Marcus,
I have now been able to resolve this issue. Here's a summary of what happened in my case:
Cause of Problem –
The default aggregation method for the measures is set to "None" in the OBIEE repository.
Resolution -
In OBIEE answers pivot table report, click on the "More Options..." icon next to the measure name in the measures column. Then select "Aggregation Rule > Sum" and this should do the trick !!
(Please note that in the as-is situation, you will see that the Aggregation Rule is set to Default - you have to change this to SUM).
This is how it worked for me.
Hope this helps. Please do let me know how you get on with this.
Best Regards,
Piyush

How to build the Logical cube and physical cube

Hi All,
I have to build the logical cube and physical cube ,i dont have idea about this ,that means i think for that we have to do the partition for the cube
may i correct , correct me if i wrong ,plz help me on this
Thanks

Hi,
1. Firsty, logical model and physical model are the terms ,which we generally use in the context of database modelling excercise.
2. Coming to essbase, I am not sure ,what exactly you are trying to co relate . but as you termed 'partitions'. There is one of the types in partitioning called 'Transparent Partition'. Where, you have one cube ( which has data in it) and you can have one mroe cube ( which actually has no data in it). But it can be connected to the former cube with the help of transparent partition. This way, you have 2 cubes , but only one cube has data in it.

Are there any Oracle OLAP ODI Knowledge Modules for Oracle Olap 11g ?

Hi guys, wasnt sure where to post this so I put it here and the ODI forum
Does anybody know when Oracle OLAP Knowledge Modules, will be available for Oracle Olap 11g. It appears that the knowledge modules released with Oracle Data Integrator 10.1.3.5, currently only work with Oracle Olap 10g...
If there is no timeline, does anybody know of work around to get ODI reverses working on Analytical Workspaces built in Oracle Olap 11g
Thank you
Richard
Edited by: RichardSmith on May 15, 2009 11:51 AM

Raise a service request with Oracle Support (Metalink) for your system slow issue. May be, they will recommend you the workarounds for the issues which are not yet available for 11g in the form of Patches.

When and Why do we need to build a CUSTOM CUBE

Hello Experts, Could some please explain with a scenerio ..
"When and Why do we need to build a CUSTOM CUBE"
Thanks in advance
Bhalout

When and Why:
Custom cube should be think of when the constent cube is either not suitable nor available for a subject area.
If there is a content cube and but does not meet your reporting needs, then the better thing will be to adopt the content one and make changes.
