HOLAP - using OBIEE and Oracle OLAP

Hi
How to implement HOLAP in OBIEE (with Oracle OLAP cubes) as below –
1. For an aggregate table, there are 3 dimensions each one having 4 levels within its hierarchy.
2. We create an aggregate table at the lowest level of each dimension.
3. We create a cube for rest of the levels and its combination for the same measure.
Can we implement this and how?
Thanks

Thanks Nazar for your reply.
On Cube based MV usage - The idea is to have lowest level summaries in relational. Higheer level in cube based on MV. So in case there are queries that can get rewritten , they will retrieve data from the cube itself.
On hierarchies -
If we take the example of oracle provided GLOBAL application and check the product dimension -
========================================================================
CREATE TABLE "GLOBAL"."PRODUCT_DIM"
(     "ITEM_ID" VARCHAR2(12 BYTE) NOT NULL ENABLE,
     "ITEM_DSC" VARCHAR2(31 BYTE) NOT NULL ENABLE,
     "ITEM_DSC_FRENCH" VARCHAR2(60 BYTE),
     "ITEM_DSC_DUTCH" VARCHAR2(60 BYTE),
     "ITEM_PACKAGE" VARCHAR2(20 BYTE),
     "ITEM_MARKETING_MANAGER" VARCHAR2(20 BYTE),
     "ITEM_BUYER" VARCHAR2(20 BYTE),
     "FAMILY_ID" VARCHAR2(4 BYTE) NOT NULL ENABLE,
     "FAMILY_DSC" VARCHAR2(20 BYTE) NOT NULL ENABLE,
     "FAMILY_DSC_DUTCH" VARCHAR2(60 BYTE),
     "CLASS_ID" VARCHAR2(4 BYTE) NOT NULL ENABLE,

     "TOTAL_DSC_FRENCH" VARCHAR2(30 BYTE),
     "TOTAL_DSC_DUTCH" VARCHAR2(30 BYTE),

========================================================================
Now , if this was TYPE 2 dimension and if you had possibility of late arriving sales data where you need to pick up "point in time" attributes of the product. How can I model dimension hierarchy in that case in OLAP?
In the Oracle example, they have kept it simple TYPE 1 so ITEM_ID can be kept as the key. However, if I had the PRODUCT_DIM as a TYPE 2 dimension table and i was using sequence generated surrogate key as the PK of the dimension table, how do i model it in OLAP?
Thanks

OBIEE and Oracle OLAP Value Based Hierarchies

Hi there...
I have a value based dimension built on Oracle OLAP and want to map it on OBIEE Administration tool.
I've been using the above link as reference:
http://www.oracle.com/technology/obe/olap_biee/CreateBIEEMetadata.htm
There's no option to import from Oracle Multi-dimensional Database. Either to import/configure the view created by OLAP as an Unballanced or Ragged Dimension.
I also checked this example, but it uses ESSBASE as the multi-dimensional source....
http://www.rittmanmead.com/2008/08/27/ragged-hierarchy-handling-in-obiee/
How to map this Ragged Dimension created in OLAP workspace in OBIEE? Any suggestions or directions will be highly appreciated...
Thanks in advance
Marcos

Mark and others,
You can create OLAP_TABLE views with level columns on top of value-based hierarchies. BI Beans used to do that too behind the scenes in Discoverer Plus OLAP. If you trace the Discoverer session, where you are querying data from Value-based hierarchies, you will see that it also generates OLAP_TABLE views with level columns in it.
So the question is how to do it. Internally, even for Value-based hierarchies Oracle OLAP keeps track of the "depth" of each value by using a structure called GID_DIMENSION (i.e., Grouping Dimension). Here is an example of a view on top of a value-based hierarchy (CFC_ACCT_GAPP) for RPT_ACCOUNT dimension. You have to know how "deep" your value-based hierarchy is.
Similar kind of a thing is done by OLAP View Generator application, which I never use - since I always prefer to define my own OLAP_TABLE views.
This kind of a view can then be used in the RPD of OBIEE.

Using Coherence and Oracle Database as the CacheStore

We are working on implementing a solution using Coherence and Oracle Database as the CacheStore. We initially implemented the Cache as a distributed-scheme which in turn uses the backing-map-scheme. We are trying to introduce transaction management and I used a scheme-ref in a transactional-scheme to point to an already existing distributed-scheme. However when I bring up the server, my custom coherence-cache-config.xml file is not recognized and Coherence comes up with the default setting. Given below is the snippet of my configuration file.
1)     I would like to understand why the below configuration doesn’t work and am I doing it the right way? If not, what is the correct way of doing it?
2)     There are a multiple transaction management options given in the documentation. Which are the ones that will work with a distributed-scheme and read-write-backing-map-scheme?
3)     If transactional-schemes cannot work with distributed-scheme, what is the best way to have a distributed cache with a oracle database as a cache store?
<caching-scheme-mapping>
<cache-mapping>

</init-params>
</class-scheme>
</cachestore-scheme>

</read-write-backing-map-scheme>
</backing-map-scheme>
<autostart>true</autostart>
</distributed-scheme>

Hi,
If you look at the documentation for transactional-scheme here: http://docs.oracle.com/cd/E24290_01/coh.371/e22837/appendix_cacheconfig.htm#BHCIABHA
you will see that it says The transactional-scheme element defines a transactional cache, which is a specialized distributed cache. That means that a transactional-scheme is already a distributed-scheme.
You will see from the same documentation above that there is no way in a transactional-scheme to configure things like cache-stores or listeners or even the backing-map-scheme as these are not supported on a transactional-scheme - so you cannot use a cache store.
Personally I would not use transactional-scheme unless you have some really big reason to do so - the restrictions far outweigh any perceived advantage of having a transaction. There are better ways to build applications so they do not require transactions, that is what we have been doing for years with Coherence so far, and there is no real reason to change that.

Oracle OBIEE and Oracle EPM (Hyperion)

We are planning to upgrade Hyperion EPM version 9.3.3 to the latest verison but we also purchased OBIEE, and Oracle (Hyperion) Planning. I am wondering if anyone has done this and how they all integrate together. My understanding is we have to upgrade from 9.3.3 to Oracle EPM 11.1.2.x and then to 11.1.4.x. Oracle (Hyperion Planning) would be intregated into Oracle EPM 11.1.4. How does OBIEE fit in and where are the integration points?
I am trying to keep the administration to the minimum as well as plan for the future upgrades as weel. Is there any Oracle documenation on this? Has any one done this yet?

You can integrate EPM with OBIEE but as far as I know there are specific versions that can be integrated.

OBIEE 11G HOLAP( drill through) from ORACLE OLAP to Relaltional table

Hi Experts...
I have some idea that the drill through from an essbase cube to an relational cube can be possible with few limitations in OBIEE 10g. I am looking for the same feature with ORACLE OLAP option . I have OLAP cube built in 11g (leve5 - granularity to one of the dimension) , and relational has 7 levels. In OBIEE once drill down to the level 5 it has fetched data from OLAP , and going beyond to level 6 -7 then it should get the data from relational table.
Do anyone had gone through such solution, Please kndly share your inputs and documents which would be helpful.
Thanks
S

This is very easy. It's really no different from setting up OBIEE to drill from one table to another. Let's assume that you have your cube mapped in OBIEE using the OBIEE plug-in for Analytic Workspace Manager. Here is an outline of the steps:
1. Add the dimension table and fact table to the OBIEE physical layer.
2. Add the new level to the OBIEE dimension object in the business layer.
3. Add the dimension table as a new logical table source to the existing dimension table in the business layer.
4. Add the fact table as new table in the business layer.
5. Define joins in the physical and business model as appropriate.
6. Set set keys in the tables and the dimension as appropriate.
7. Set the level for the new dimension table to the appropriate level in the dimension.
Again, it's really best to just think about this as drilling from one table to another.

Using OBIEE with Oracle Express Edition Database? SOLVED

I have a client that wants a quick demo of OBIEE. They sent us some csv files as the data source. I migrated them to Excel files for easier use, but the Excel files seem to have limitations on how I can combine the columns, such as concatenating and formatting.
I then loaded them into an Oracle Express Edition database, assuming more "database" functionality would be available to me. I was able to load them into the Administration Tool, but Answers gives me the following error when I try to view any results from the Express database:
Odbc driver returned an error (SQLExecDirectW).

Latest News on MDX and Oracle OLAP (from Simba Technologies)

[http://blogs.simba.com/simba_technologies_ceo_co/2009/05/mdx-query-language-for-oracle-11g-olap-update.html|http://blogs.simba.com/simba_technologies_ceo_co/2009/05/mdx-query-language-for-oracle-11g-olap-update.html]
Excerpt from above Simba Technologies CEO blog*
One interesting thing we found from some of the Beta customers is that they thought this was an Excel only solution. Yes, we are focusing all the efforts for v1 on Excel, but this is planned to be a full blown MDX provider for Oracle OLAP*. Therefore, you will get the entire MDX query language and this interface will be similar to what you have with Microsoft Analysis Services or SAP Business Warehouse. Although v1 will be ODBO only, we are planning to support XMLA in future versions. The priorities for what we support and when will be customer driven. One question I have is after Excel, which MDX application do you think we should test with and support next:
1. SAP Business Objects Crystal Reports
2. SAP Business Objects Voyager
3. MicroStrategy 9
4. Microsoft Reporting Services
5. Microsoft SharePoint BI
6. IBM Cognos Business Intelligence 8
7. Panorama NovaView
.

Thanks very much for your response. Pls find the details as requested. You can reach me in [email protected]
Environment Details
- BO XI 3.1 SP4 Enterprise Premium (incl Voyager) on Win2008 R2 [Tomcat Flavour]
- Oracle 11.2.0.1 Enterprise Edition with OLAP on AIX 6.1
- Simbha MDXProviderForOracleOLAP v2.1.0.23 on Win2008 R2
Cubes are built using AWM 11.2.0.2A.
To be more specific, the issue occurs when we attempt put a filter on the dimension (or select members of the dimension) both in the existing workspaces or when we try to create a new workspace in Voyager. Attaching the screenshot of the error message.
Kindly let us know incase you would require further information. Also, if you would like to have a webex session where I can show the issue, I am happy to do the same.

OBIEE and Oracle Apps (E Business Suite) SSO implementation

Hi Gurus,
We are using apps 11i and OBIEE 10.1.3.4 . I would like to ask that is there any doc which could provide me steps of SSO implementation between both. Or if not in doc is there any body who incorporated the same. Here we dont have DAC and ETL as Informatica for etl we are using plsql. I want to make it work like when user types his id and password in Oracle E business , automatically he should be also directed to OBI also same user id and password could be used to the OBI. Please remember my OBI is not from apps package. It is EE and not OBI 7.9.6 So is it possible to implement SSO between OBIEE and apps 11i and how ?
Thanks,

Though this is not your complete answer, at some point this link might be of help to you if you have OBIEE hosted on Windows box.

Physical size of dimensions and composites (Express and Oracle OLAP)

Hi, have a rather odd question re: the physical size (in bytes) of composites...are they affected by the dimension sizes?
I.e. if I define a dimension "Org" as:
define org dimension text width 10
will that result in smaller composites than if I define it as
define org dimension text width 30
? i.e. given that everything else if equal (same number of values, same # of tuples, etc.) does the physical definition of how wide a dimension is affect the size of the composites that use that dimension?
p.s. need to know this for Express, but if Oracle OLAP doesn't behave the same I'd like to know that also.
Thanks!
Scott

A 5 dimensional composite has keys built of 5 4-byte dimension positions. There is a copy of the 20 byte value stored indexed by physical position that we use internally to determine the value of the base dimensions. Also there is a copy stored in a hash table used to take the base dimension values and convert those back to a physical position (that's 20 bytes for the key and 4 bytes for the physical position).
Finally, we have internal structures ("inversions") that we use to essentially do "limit composite to base dimensions" for looping (for each base dimension value, a list of physical positions that have that base value in it), at 4 bytes per dimension or another 20 bytes.
That's 64 bytes. Yeah, it's not cheap, but compared to a dense variable, you save a ton of space. I seem to remember a calculation someone did a long time ago that said that composites were net smaller for anything less than 20% dense.
I'm not surprised that under certain conditions you can find a better data layout. Certainly the overhead of storing dense data is tiny compared to a composite. If you are clever (or lucky) in your segmenting, you can take advantage of the "holes" in the data to improve the storage. The "holes" (large groups of NA values) can go for many pages, if the faster varying dimension size is large, and won't be stored.
Oracle OLAP contains various improvements over the Express code. I believe we now use compressed bitmaps to store the inversions, rather than lists of values, for a substantial savings. There may be other changes as well (I'm not current on the details of the dimension storage).
Hope this helps.

Reports Requirements using R12 and Oracle 10g Reports

Hi All,
Looking forward to some valuable inputs to propose a technical solution in R12 using 10g Reports Developer.
Requirements are :
1. Report output should be in Excel Format. ( Is this possible without XML Publisher using 10g Reports only )
2. Report Parameters to have multi selection criteria. ( Is this possible in 10g Reports and Oracle Apps, Report Manager responsibility ?)
Regards,
Anand

>

Database locking using JSP and Oracle database

Dear All
I am reading about how to do database locking in general and i want to implement these mechanisms using JSP pages and oracle database, but i have the following questions:-
1.If i write a “select for update” quesry in the JSP page will it locks the record ? or it will not lock the record because the connection between the JSP pages and the server will be stateless in most online systems?
2.If i write all my jave code in transaction , something like this:-
• Begin transaction
• Commit or
• Rollback
Then should i be worried about the locking issues or the database manger will handle the locking mechanisms to insure data integrity(and what the default mechanism (if any) that the oracle database manger use to do the locking)?
3. If the answer for question 2 is no, then how can i handle the optimistic and the pentemistic locking using JSP pages?
BR

One way to solve this issue is as follows:
* You add a new column to each database table called 'version' which is of int type.
* Each time you alter any field in a record, you increament the version number.
* When you read a record and display it, you store the version number in your code
* when you go to update the record, you write your sql something like this:
update person set firstName=? where personId=? and version=?
Where the version is whatever you stored locally. If someone altered the record in the database while your
end user was looking at it, the version numbers will not match and the sql statement will
return zero as the number of records it altered. If its zero, inform the end user someone altered the record
while he was looking at it and weather or not he wants to proceed.
The chances of two people altering the same record in a table while both are logged in and viewing the same set of data is small so such collisions will be few.
You only need transactions if you are updating more than one record at a time (in the same table or multiple tables).
You dont need it for reading records if you use a single sql statement to read (for example: to join multiple tables).
In general, you get a (pooled) connection, use it, and close it as quickly as possible in a try/catch/finally block. You dont hold onto it for the duration of the user's session. A book on JDBC should help clarify this.

Example of a successful reverse proxy to APEX using Apache and Oracle HTTP

If this helps anyone, I was able to set up a reverse proxy to APEX with Apache running on the reverse proxy server and Oracle HTTP server and APEX 3.2 on the APEX hosting server. I want to post this due to there is no
documentation on this that I can find. Oracle Metalink could not produce any "How To" document either.
On the reverse proxy server in the httpd.conf file:
ProxyRequests Off
SetEnv force-proxy-request-1.0.1
SetEnv proxy-nokeepalive 1
ProxyPassReverse /pls/apex/ http://apex_server:8080/pls/apex/
ProxyPass /pls/apex/ http://apex_server:8080/pls/apex/
ProxyPassReverse /i/ http://apex_server:8080/i/
ProxyPass /i/ http://apex_server:8080/i/
AddType text/xml .xbl
AddType text/x-component .htc
OR
ProxyRequests off
RewriteEngine On
RewriteRule ^/pls/apex/(.*)$ http://apex_server:8080/pls/apex/$1 [P,NE]
ProxyRequests off
ProxyPassReverse /i/ http://apex_server:8080/i/
RewriteEngine On
RewriteRule ^/i/(.*)$ http://apex_server:8080/i/$1 [P,NE]
And in the Oracle HTTP server httpd.conf file of the APEX hosting server:
NameVirtualHost 999.99.99.9:8080
<VirtualHost 999.99.99.9:8080>
ServerAdmin [email protected]
DocumentRoot "/u01/app/ora11g/product/11.1.0/http_1/ohs/htdocs"
ServerName reverse_proxy_server.com
</VirtualHost>

Here is what I saw :
I have one Web Server 7.0 instance with the following obj.conf :
<Object name="default">
<If $uri =~ "/xyz">
NameTrans fn="map" from="/" name="reverse-proxy-/xyz" to="/"
</If>
<ElseIf $uri =~ "/abc">

</Object>
<Object name="reverse-proxy-/xyz">

</Object> ...When I send a request to URI :
/abc/test1.html : the request gets served from server1 from docs/abc/test1.html.
/xyz/test2.html : the request gets served from server2 from docs/xyz/test2.html
Where as when you change obj.conf to (note the change in "from" parameter in "map" SAF)
<Object name="default">
<If $uri =~ "/xyz">
NameTrans fn="map" from="/xyz" name="reverse-proxy-/xyz" to="/"
</If>
<ElseIf $uri =~ "/abc">

</Object> ...In this case when I send a request to URI :
/abc/test1.html : the request gets served from server1 from docs/test1.html.
/xyz/test2.html : the request gets served from server2 from docs/test2.html.

OBIEE and Oracle Apps

Hi,
We have OBIEE integrated with Oracle Apps. During installation we also get the Vanilla rpd. we are also using another new module which uses another database but not the Oracle apps. We have requirement of OBIEE reports on this module. This databse is an OLTP database. We are trying to add another source to the rpd and pull these tables and create a subject area. My understanding is that this is possible. So we will have two sources. One that came in the vanilla rpd which is datawarehouse and the other which is OLTP for the new module. Please correct me if I am wrong. Thanks.

hi User,
You are doing correct let me add some points
which uses another database but not the Oracle apps. We have requirement of OBIEE reports on this module. This database is an OLTP database.You have Different connection pools by default when u install oracle Apps next,you are customizing the rpd by adding some OLTP database ,
Merging the Vanilla rpd + Custom rpd (i mean connection pools)
make sure that all the join conditions to be made and report should be from theis subject area
thanks,

Using Notes and Oracle Client in the same application on Linux crashes

This thread is copied from a thread of the same name under Database - General, since I cannot get any replies there.
Could someone from Oracle PLEASE comment on this.
Our application on Linux loads the Notes client libraries and then the Oracle client libraries. The application will crashes when connectimg to an Oracle server. This is because the T_* symbols in libnnz11.so get fixed up into libnotes.so rather than locally into libnnz11.so where the functions are defined.

We have circumvented the problem for the time being by making sure that we load the Oracle libraries before Notes, but we cannot go with that as a long term solution.
In my opinion the Oracle library is wrongly linked since all the T_* functions are defined in libnnz11.so. When we load Oracle first, the loader debug trace shows the correct fixups. When we load Notes first, the loader trace shows the incorrect fixups. We are using dlopen(libor9i.so, RTLD_LOCAL) for Oracle and dlopen(libnotes.so, RTLD_LOCAL) for Notes. libor9i.so has a dependency on libclntsh.so.10.1.
An opinion would really be appreciated.
Thanks,

Thanks again.
We don't have an Oracle support contract because we do not use Oracle ourselves. We supply an application that synchronises data between multiple data servers and server types, of which Oracle is one and Notes is another, as well as LDAP servers and many other types.
Producing a full resolved binary is therefore not an option since the types of data server are configured when the apploication is installed, and then the client software for each server is loaded as required.
The end user of the application supplies the client libraries and has a support contract for the servers, in particular Oracle and Notes in this case. So the other option is for the end user to raise a ticket using his support contract, but he is reluctant to do that since he considers that this is our problem as we supply the application that is having the problem. So we are in a dead water area. We do not want to take out a support contract just to get what is an Oracle product problem resolved. I imagine that this problem is something that has not been encountered before, because our use of the client library in conjunction with other client libraries is probably unusual.
So that is why I am hoping, without any success so far, that someone from Oracle will pick this up.
