Metadata Repository : star schema

hi,
*how do you export star schema to excel?*

Hello,
Star schema is a Concept on which BW is based. If you want to transport Star Schema to Excel, you should instead look at all the Dimension tables, associated Fact tables, master data tables, SID tables for it to make sense.
Hope this helps.

How to display BI Content provided infocube as star schema

I go to Matadata Repository>BI content> and then where to next?
There is supposedly a a setting somewhere in the MDR to choose schematic display as star schema.
FYI I want to view one of the available infocubes 0cca_c11 as start schema layout in the BI7 version.
And I also do not see how to view only acivated objects in the BI content or metadata repository....
Thanks

Hi Natalie,
you can use the tcode listschema to display the cube in schematic view.
we can get the active objects informations from these tables.
for info objects : RSDIOBJ make appropriate selections like version as A and status as ACT - active and executable
RSDODSO for data store objects
RSTRAN for transformations
RSDCUBE for cubes
RSDS for data sources (give source system and version)
you can find the active objects information from these tables in se11 or se16
Thanks,
Sathish.

Star Schema Image-Urgent

Hi All
Can any1 tell me from where in the BI system can i save a .jpeg image of a Info Cube Starschema.
I have been doin thru Metadata repository, I can see the star schema tof my cube there but when i copy that to a word file, most of the dimension parts are missing,, so im nt able to copy the complete star schema, I cant reduce the Zoom also, So is there any way to save it.
Is there any Such Export Button in the metadata repository Window.
Points are assured.
Thanks

There is option to export the html document for the object being displayed. Menu Extras-->Html Export, the export option is also available with the context menu of the object. Try this if you need for a specific object only..

9.0.4.1 Metadata Repository in 9.2.0.6

I just upgraded my 9iAS infrastructure and mid tier with BI and Forms from 9.0.2.3 to 9.0.4.2. We had all the components on one server except we had a separate 9.2 db for our portal repository.
I want to know how to migrate my metadata repository to a different server and use database version 9.2.0.6. Are there any documents or specofic sections of documents which could guide me in this migration?

I am not familiar with the document you refer to, but suspect you should apply the 9.0.4.2 patch if you want to integreate OCS with a 10g portal.
I have successfully integrated a 9iAS portal with R2 OCS (9.0.4.1), and the following details may be worth a closer look:
1. To my knowledge, the passwords for your portal user and SSO user (orasso) are encrypted and stored in OID based on the hostname and IP address of your SSO server. Thus, the password for orasso and portal will differ between your portal Infra and your OCS infra, resulting in that only one of the two will work properly with your common OID. run the attached script on both your SSO servers and compare the result:
#!/bin/ksh
OIDHOST=antares1.i2sp.no
OIDPORT=4032
echo "Enter the desired Oracle schema name (default orasso): \c"
READ DBUSERNAME
if [[ -z $DBUSERNAME ]]; then
echo "No schema value entered, using default:orasso"
DBUSERNAME=orasso
fi8
echo "Enter the password of the cn=orcladmin user (usually the ias installation password): \c"
stty -echo
read OIDPW
ty echo
echo "Looking up schema password from $OIDHOST:$OIDPORT"
$ORACLE_HOME/bin/ldapsearch -h $OIDHOST -p $OIDPORT -D "cn=orcladmin" -w "$OIDPW" -b "cn=IAS Infrastructure Databases,cn=IAS,cn=Products,cn=OracleContext" -s sub "orclResourceName=$DBUSERNAME" orclpasswordattribute
Setting the password for orasso and portal to the same encrypted string is a good start. If they differ, change to the same encrypted string using "alter user orasso identified by xxxxxx" in sqlplus.
Hope this will help you on the way :-)

Design Fixed Assets Star Schema from OLTP DB

Hi,
Scope : Design Fixed Assets logical Star Schema for Demonstrate with OLTP tables
Our platform is Oracle 10g Forms and Reports deployed on Oracle 10g App Server._ At the moment we don’t have data warehouse constructed. We are pumping OLTP Data into Staging DB thru jobs and then by using materialized views getting the data in DWH DB which is in progress.
OBIEE 10g installed and working fine for testing.
We are planning to implement OBIEE for Reporting. As a starting point I would like to design Fixed Assets star schema to demonstrate FA reports in OBIEE from OLTP Tables.
FA- OLTP Tables:_
AC_UNIT_MASTR           – Business Units
AC_ACNT_MASTR           - Nominal Codes
AC_COST_CENTR_MASTR      - Departments
AC_MANTN_ASTS           - Assets transaction table
AC_AST_BAL_DETLS           – Period wise Asset summary
AC_AST_BAL_DETLS_V      - View
To achieve this
1).Import tables in physical layer and set physical joins
2).identify and create dimensions and set complex joins and then move to presentation layer.
Please suggest best approach to design Repository
Thanks

Kulkarni

Hi Saichand,
Thanks for the response.
Already i referred that doc and completed practically. now i have to work on Finance data . as a starting point working with Fixed Assets module. already i designed centralised fact with dimensions as below
in physical&BMM layer defined relationship as below()
AC_UNIT_MASTR_D                  --> AC_AST_BAL_DETLS_F
AC_ACNT_YEAR_MASTR_D        --> AC_AST_BAL_DETLS_F
AC_ACNT_PERD_MASTR_D        --> AC_AST_BAL_DETLS_F
AC_COST_CENTR_MASTR_D      --> AC_AST_BAL_DETLS_F
AC_AST_GRP_MASTR_D            --> AC_AST_BAL_DETLS_F
AC_AST_SUBGRP_MASTR_D      --> AC_AST_BAL_DETLS_F
and
AC_ACNT_YEAR_MASTR_D        --> AC_ACNT_PERD_MASTR_D
When iam trying to create a dimension for Periods(AC_ACNT_PERD_MASTR) , Periods dimesnion created with two tables
AC_ACNT_YEAR_MASTR_D,AC_ACNT_PERD_MASTR_D
Please advice..

Applying 10.1.2.3 Metadata Repository update in 10.1.4.3 distributed IDM

Hi there, I seem to have a unique issue.
I have the following config of 10.1.4.3 IDM :
SSO in a separate Oracle home
OID in a separate Oracle home
DB (10.2.0.50) in a separte OH and metadata repository installed in this DB
and this is set up in ASR replication mode with other similer setup.
Task : Apply 10.1.2.3 OracleAS patchset.
The story:
To be fully compliant according to Orcale we ned to apply 10.1.2.3 patch. This patch has two components - a software update and a Metadata Repository (MR) update.
I have applied software update to all the Oracle homes above (with the exception of DB ofcourse).
But to apply MR update I have to do it from a mid-tier OH that also has MR installed, I have none.
I tried installing MR update from SSO and OID oracle home but it would not allow me , I got this message :
The Metadata Repository Update cannot be run from the selected ORACLE_HOME.
The Update must be run from either an Identity Management with Metadata
Repository installation ...
But we have no middle-tier using this MR, and from this metalik note, it seems applying MR update is not mandatory, only a desirable housekeeping execrcise . :
Understanding How AS 10g Patch Sets Update the AS Metadata Repository [ID 795143.1]
Exract from that note :
a. apply the binary update to each AS Oracle Home in the AS Farm.
b. finally, if possible apply the MR update exactly once from any home that allows it to be run.
also from the same note :
Scenario 6: Applying the 10.1.2.3 AS patch set to a 10.1.4.3 Identity Management home.
The 10.1.2.3 AS patch set is a required patch set, as documented in :
Note: 465847.1 Oracle Identity Management 10g (10.1.4.0.1) Release Notes Addendum.
In this case, the MR Product schemas will not be directly accessed. It is however good practice/ housekeeping to apply the MR update in order to keep the MR in line with the binary patch sets.
My question :
I am correct in my understanding that apply 10.1.2.3 software update only is neccessary, applying the MR update is only desirable house keeping and not mandatory ?
Would you say this is the correct assessment. if not how would you go about applying the MR update ?
Thanks in advance for your answers.

Star schema versus snowflake schema

I have a question regarding dimensional data modeling. My question here is, when star schema model would be useful and when snowflake schema model would be useful.
In star schema, we have only fact and it is connected with dimensions. But in snowflake schema, we are normalizing dimension into one more level. Let us say, we have dimension product. Product can be normalized into another table called supplier. Let us take another example, customer dimension. Customer dimension can be normalized into country…
Advantage of star schema is, easy to write the query since we have only less tables. You do not need to join multiple tables when we write the query. It would improve the performance some time.
Advantage of snowflake schema is, it is little complex to write the query, since we have to join multiple tables. Performance might improve some time when we join smaller tables…
My question is, at what circumstances, we can use star and snowflake schema? I am not able to define the word sometime_
Any help is highly appreciated…

Hi,
There is a trade off on the availability and the Complex analytics.
A star schema is good if you have the functional requirements really simple. Like the dimension is not SCD Type2 (slowly changing dimension) and you don't need to do "AS IS" vs "AS WAS" reporting.
In modern Analytics in any domain dimensions are SCD Type 2 as business keep on evolving. In a star schema structure this will cause explosion of data if there are frequent changes at the higher levels of the dimensional hierarchy. That anyway will hit the performance.
As far as my experience goes, at the data model level it is better to have snow flaked dimensions. and while managing the metadata (in a BI reporting tool) you can consolidate the snowflaked dimensions in star schema structures. That will make ah hoc analytics much simple for the business users.
A lot of performance measure can be taken to improve the end user experience.
In short the trend in BI analytics demands to have a snowflaked structure rather than a simple star schema structure.
Hope this helps.

Invalid log directory in Metadata Repository Creation Assistant

Hi all,
I have on my laptop with OS Vista 64bit installed database version 10.2.0.3.0 and standalone AS (resp. whole SOA Suite) version 10.1.3.3. I wanted to install and configure OID not to separate, but to existing database. At first, I downloaded and successfuly installed Metadata Repository Creation Assistant (as_windows_x86_mrca_101401_disk1/2.zip). But when I run Oracle RepCA, in step 1 of 2: Specify Oracle Home Path, I get error Invalid log directory.
As Oracle Home Path I typed D:\oracle\product\10.2.0\db_1 (as it is in registry)
As Log File Directory I tried D:\product\mrca\assistants\repca\log, D:\log etc.
Could you help me, how to solve it?
Thanks,
Peter

There is a Patch for Windows Server 2008.
-->
Patch 7497474
Description: 10.1.4REPCA ON WIN 2008: NOT ABLE TO LOAD SCHEMAS USING REPCA INTO THE DB
For me it was the solution. Install the patch (follow the instruction in the readme.txt)
After that the RepCA accepts the Log File Directory.

Is 10.1.4.3 Metadata Repository Certified With 10.1.4.1 IM installation?

We have IM 10.1.4.3 and OracleAS 10g R2 10.1.2.3 on RedHat 4.6 with non-colocated metadata repository.
Plan is to upgrade RedHat to newest version 5.5. RedHat does not support upgrade with major version and Oracle said that OS vendor is responsible for package compatibility and there is no need for relink Oracle software.
So, only solution is to do fresh install OS, IM and OracleAS.
My question: is it possible to install IM 10.1.4.1 against higher version of metadata repository? Is there any workaround?
tnx in advance

"# Error: Already exists" suggests that schema at AD side is already extended. You mentioned that automatic schema upload process stopped abruptly. There is likely chance that AD schema might be extended partially or fully.
2nd thing is you can apply BP05 patch once you have identity server running. BP05 does not need to be applied before.
Also there is option to manually extend schema directly in AD. There is one folder in installation directory which has .ldif files with schema objectclasses.
At the start of identity server , it is not able to find the configuration DN & seach base to read configuration data , therefore it is failing.
You have two options here: 1. Reinstall 2. Manually extend schema and then install identity server.

How to document your star-schemas and dashboards?

Hello practitioners,
We are new to OBIEE and started some weeks ago. We are a two-men team. One guy doing all the data design and the other for everything around Answers.
So it happens regularly that the other guy has to ask the one guy, about the exact definition and meaning of data-fields, he wants to use in Answers.
Being a real programmer the one guy only needs a proper, self-explainary field name as documentation, of course (or so he thought).
Question:
What tools and methods do you use to document the star-schemas and dashboards?
Being the other guy, it is important, that I pick the correct fields, while on the other hand I do not want to disect a dashboard I built a while back, everytime somebody wants something simular, just to figure out what I actually did, back then...
Thank you for your help

Edited by: Turalf on Mar 24, 2010 12:03 PM

Hi Turalf,
Have you looked at the OBIEE Metadata Dictionary ? A method to allow answers users to gain access to column definitions, and you can view the mapping from Presentation, through BMM to Physical layer.
Im pretty sure you can expose comments from the RPD into this also.
http://obiee101.blogspot.com/2008/12/obiee-metadata-dictionary.html
Maybe you could look at the ODI - OBIEE data lineage also, it provides "report to source" mapping info :

Can Portal and OID Metadata Repository be shared?

Hi
I am designing a solution for my client which includes Portal and OID implementation. I was then posed the question whether the portal and oid metadata repository should be shared. Is there any best practice that anyone can share? Thanks!
Regards
Dave

Hi Dave,
I had faced this question once & I opted to use a separate Database for the Portal Schemas.
I am not aware of any document that details the best practices - but, my deisgn was based on the fact that the Portal Schemas would grow in future based on the number of Portal Pages & Applications. Our Client had forecast hat they would be using Portal quite heavily & hence, a separate MR was the way to go for us.
We just installed a new Oracle Database, used the Oracle Metadata Repository Creation Assistant & registered the database with Oracle Internet Directory. During the installation of Portal, the Oracle Universal Installer offers a choice of Metadata Repositories for the Portal Schema.
