Integrate OLAP with OBIEE

Hi,
I'm trying to integrate OLAP with OBIEE, so in that process i'm using OLAP cubes created using AWM(Analytical Workspace Manager) in OBIEE. Using the cube, created the repository file as explained in the following link of Oracle site.
http://www.oracle.com/technology/obe/obe_bi/bi_ee_1013/olap/CreateMetadata.htm
I have followed exactly the same steps in creating the cube and repository file. But my problem is when i'm trying to run the requests in BI Answers, those are taking long time to give the results. I tried in different ways by making small changes in cube and repository file but no progress. I read in many of discussion forums and whitepapers that MOLAP Cubes give 10 times greater performance compared with normal tables for data retrieval, but in my case its not happening.
I want to know whether any tweaks need to be performed at the Memory side or in the design process to get rid of my problem. Please let me know if any one of you tried integrating OLAP with OBIEE.
Thanks in Advance,
Kumar.

One thought....
In BI EE you must map an additional top level, even for year (All Years) to force BI EE to pass a LIMIT statement to the AW even if the dimension is not included in the query. Otherwise, all values for that dimension will be returned to BI EE and this will cause a huge performance bottleneck.
You can test the performance in two ways:
1) In AWM use the OLAP Worksheet and execute a limit command for each dimension that would use in your BI EE query. Then issue an RPR command to view the data and check the performance. Obviously you will want to limit the amount of data. Don't try to return the whole cube as this does not make any sense.
The RPR command will replicate the level of performance you can expect in BI EE.
2) Using SQLPlus create a SQL statment to return data from the relational view over the AW. Make sure specify a where clause statement for each and every dimension. If you fail to use a where clause for a dimension every single value for that dimension will be returned.
There are specific OLAP init.ora settings you should review and modify according to your server configuration. These are all documented in the OLAP installation document. Make sure you have read this carefully.
If performance is still not meeting your expectations then trace the SQL being generated and look at the wait events to determine where the bottleneck is within your system.

How to integrate Siebel with OBIEE ?

Hi,
I need a favor from you guys. Kindly let me know the procedure to integrate Siebel with OBIEE.
According to our requirement we have to integrate Siebel 8.0 version with OBIEE 10.1.3.4 version. Kindly provide me the necessary steps/inputs so that i can integrate Siebel with OBIEE.
Thanks in advance.
Regards,
Samdev

Hi all,
@Stijn: With regards to OBIA-specific screens I definitely agree with you. Not so sure about the basic integration though. The Integration Administration screens are normally available.
Key item to have is the ROW_ID (or "INTEGRATION_ID" if you're talking OBIA context) in order for the integration to work...i.e. be able to jump from OBIEE to Siebel.
The responsibilities are the other issue. Your approach is 100% sound and I'd keep that one in mind (@user8681498). I have never tested Siebel integrated OBIEE without OBIA where the security is concerned so I somehow doubt that the hand-over of usernames and the attached responsibilities for transformation into web groups works immediately.
@user8681498: For the tables missing from the Siebel schema, those are mostly OBIA related tables - i.e. for data loading purposes rather than for authorization or integration mechanisms.
Cheers,
C.

Integrate EPMSystem11R1 with OBIEE 11.1.1.3

Hi Guys,
We want to integrate the Hyperion EPM 11R1 with OBIEE 11g with SSO? basically when user should be able to run a OBIEE report from Hyperion seamlessly without entering username passwords in OBIEE. has anyone done this or any documents?
Thanks

Neal,
This is supposed to be one of the big fixes in OBI 11g (11.1.1.6), so if possible I would wait until that gets released this year.
Otherwise if your organization is using SSO across its applications the log in won't matter if you have SSO enabled on both the EPM and OBI applications.
Remember, also , that you now have the OBI action framework which can potentially have you open an HFR report from OBI without passing credentials

Connecting SQL Analysis Services 2005 cube with obiee 10g

Hello experts,
I'm trying to link an SQL Analysis Services 2005 cube with obiee 10g.
In Oracle BI Administration, when I choose File -> Import -> From
Multi-dimensional, I have to fill the next gaps:
Provider Type: Analysis Services 2005
URL: ***********
User: blank
Password: blank
Before to do that, I need to create the URL path.
To create the URL, I have followed this link.
http://erpthings.blogspot.com/2008/08/obiee-connection-to-msas-2005-
cube.html
But, it hasn't worked because when I was trying to configure the HTTP
access to SQL Server 2005 Analysis Services, we have to perform a test to ensure that it has been well configured. In IIS -> WebSites -> Default WebSites -> olap, we should browse the document called "msmdpump.dll" and this should show an xml document, but it doesn't.
Thanks!

Hi Alex
It sounds like your MS data pump might not be configured correctly. First ensure that is working before trying to put the values into OBIEE. Don't worry about the 500 error - I get that too instead of an XML page.
You can read a bit more about SSAS support on my blog here:

Oracle OLAP as OBIEE Data Source

I've got a couple of questions regarding the use of Oracle OLAP (Analytic Workspace/Cube) as an OBIEE data source.
First: As a general rule when creating a dimension, we create a total roll-up for the dimension i.e. "Total Product", "Total Geog", "Total Customer" etc... Generally, I don't create a total roll-up for time dimensions. When importing metadata from OLAP to OBIEE, OBIEE creates a "Total" level for all dimensions. Now, I understand why OBIEE does that; to support queries that might exclude one or more dimensions. My question is: what is the best method/procedure to deal with the extra "Total" level?
Second: I would appreciate it if someone could explain this error for me: [nQSError: 59137] Filter level YEAR is below the projected level Total on dimension CMP_TIME while an externally aggregated measure is present. (HY000). I understand the words, but have no clue what OBIEE is trying to tell me. This error pops up constantly and I see no rhyme or reason that would cause it. the specific case above occurred when I clicked on the sort icon for a measure included in a report.
Thanks,

Mark,
Thanks for the reply. However, I'm not sure I made myself clear. I have created a "Product" dimension in AWM (Analytic Workspace Manager) in the following structure: Product -> Product Line -> Total Product. Withing the context this hierarchy, "Total Product" is the "Grand Total" Level. When this data is imported into OBIEE using "Oracle OLAP" as a data source, the Product hierarchy is created in the Physical Layer as an "Oracle OLAP Dimension". In the BMM Layer, the hierarchy is structured as: Product -> Product Line -> Total Product -> Total. There are now two "Total" Levels. Naturally only one, the OBIEE generated Total, is defined as "Grand Total". The only child of the Total level is Total Product. I have two hierarchy levels that are the same. So, do we need both? should we keep both? Should a dimension defined within AWM for use in OBIEE NOT include a total level? It's not really a problem, it just doesn't seem to make any sense to have TWO total levels within a hierarchy.
On the second issue, I wish I could provide some detail, but I'm really not sure how I'd do that. That's why I asked for the meaning of the error. What is OBIEE telling me that I'm doing wrong. All I really did was import the metadata, drag it to the BMM Layer, deleted some of the hierarchy level keys, renamed some columns and dragged the stuff over to the Presentation Layer. So, it's pretty much drag-and-drop.
Another example of the error: We have a Category Dimension (Sub Category -> Category -> Category Group -> Model -> All Categories -> Total) and I want to see the top 10 values of a measure by Category by Model. In an Analysis, adding the Model column works fine, just not the best visualization. Move the Model column to "Sections" and all works; move the Model column to Pivot Table Prompts and it errors. Obviously, I'm asking OBIEE to do something it doesn't want to do, so I'm looking for the root cause of the error.
Thanks,

OLAP vs OBIEE Cubes vs Data Warehouse Cubes

Good afternoon,
Could someone please tell me the difference between the cubes created using Oracle's Analytic Workspace Manager, the cubes created in OBIEE, and the ones created in Oracle Warehouse Builder? Do these all use Oracle's OLAP functionality, or are they different things?
Thank you.

I think by Datawarehouse cubes, you mean the traditional relational ROLAP cubes.
It has been a long time now that OLAP engine was merged into Oracle database (starting with 9.2 version), so multidimensional MOLAP cubes can be created inside an Oracle-based DW as part of Aggregation strategy (in addition to MVs or instead of MVs) to improve query performance and simplify calculations.
Some other points.
(1). OWB can create both ROLAP cubes and MOLAP cubes. Even ODI has knowledge modules to create MOLAP (i.e., Oracle-OLAP) cubes.
(2). OBIEE cannot create Oracle-OLAP cubes in the database. I think there is some new functionality to create Essbase cubes through OBIEE, but there is no out-of-the-box functionality to create Oracle-OLAP cubes through OBIEE.
(3). The process to create Oracle-OLAP cubes using AWM and then import those into RPD is very simple. Starting with OBIEE 11.1.1.5, it understands oracle olap metadata in standard Oracle database dictionary. So when Oracle-OLAP cubes and dimensions are queried, obiee generates physical queries using OLAP_TABLE fuction, and that is how data is retrieved from OLAP engine into relational engine and then into BI server.
(4). Oracle OLAP cubes are always created in Analytical workspace, which is a table prefixed by AW$. So one quick way is to check the tables in your schema and see if there is any table with AW$ prefix.
You can also query Oracle-OLAP metadata to see what (if any) Aanalytical workspaces, MOLAP cubes and MOLAP dimensions exist in your database. Refer to Oracle OLAP Dictionary Views at http://docs.oracle.com/cd/E11882_01/olap.112/e17123/admin.htm#i1006325

Oracle IRM integration with OBIEE

Hi! I need to integrate Oracle IRM with OBIEE. Is it possible? Is there any paper or document that explains how to do it? This would be very helpful. Thanks!

The IRM integration with Beehive was developed by and is maintained by the Beehive team, you may be able to get more help on the Beehive forums (http://forums.oracle.com/forums/category.jspa?categoryID=180). In the meantime I'll try to answer your query to the best of my knowledge.
The ClassificationId can be can be any text that you wish to use to identify the beehive classification e.g. Beehive Classification ID.
The ClassificationLabelName should be used to identify the Beehive classification to the user, it will be displayed in the IRM user interfaces in places such as the information bar.
The ClassificationSystemID and KeySetUUID values should each be set to their own UUID. You can generate one on linux using uuidgen.
The DesktopSyncURI and the DesktopURI values should be set to the IRM classification url e.g. https://irm.example.com:16101/irm_desktop.
The IrmDesktopServiceEndPoint should be set to the IRM server url followed by /irm_sealing/desktop_services e.g. https://irm.example.com:16101/irm_sealing/desktop_services.
The IrmSealingServiceEndPoint should be set to the IRM server url followed by /irm_sealing/sealing_services e.g. https://irm.example.com:16101/irm_sealing/sealing_services.
The IrmUserName should be a valid user that can log into IRM and Beehive
The IrmUserPassword should be the password for the above account
The other values can be left blank.
The ClassificationServices error from IRM is likely to be related to the xml file in the classification plug-in jar file. The most frequent causes of those have been where XML editors have reformatted the example configuration changing things like
<uuid>2de4af00-3b14-11de-8a39-0800200c9a66</uuid>
to
<uuid>
2de4af00-3b14-11de-8a39-0800200c9a66
</uuid>
The fussy XML parser then refuses to parse the UUID properly because of the surrounding whitespace. This is most likely to be a problem with fields that take UUIDs, so probably just worth checking those first.
Hope this helps,
James
