PAS - Connection to Oracle data warehouse

Hi,
We are looking to connect to an Oracle data warehouse and have installed an Oracle client on the server.
We created the link ID and are using the built in connection to Oracle OCI.DLL. However we get an error back saying that it could not load the OCI.DLL
Any ideas?
Colin Cooper

Hi Robert,
I'm confused Pedro. What is the NW Database Instance? Is this another installation of CE? Or is this the relational database running behind CE? More confusing is the fact that you say SQL Server is installed on the "Database Server". If SQL Server is on this machine, why is Oracle in the picture?
Because of the system landscape this customer have, we use a distributed system instalation of NetWeaver (NW), that is composed by:
- Central services instance (SCS)
- Database instance (DB)
- Primary application server instance
The database instance is the one installed in the Database Server.
Also MS SQL Server is installed in the same server, because it's used as sytem database for SSM (store all the metadata of SSM).
Finnaly, Oracle is the database used by the Datawarehouse, the place we should connect to get all the data to load into PAS database. This is a different server.
I understand that. My question is, does Oracle have a fix for this issue available? Have you checked metalink to see whether or not a recent Oracle patch set, or the most recent Oracle client, already has a fix for this issue?
I did not check that. I will check with the customer what is the version currently used and if exists any fix this issue.
I have a machine running Windows 2003 Server 64 with the 32bit Oracle client installed and have no issues with setting up an ODBC connection to Oracle. What I had to do though was ensured that I ran "C:\WINDOWS\SysWOW64\odbcad32.exe" and not the standard "%SystemRoot%\system32\odbcad32.exe" which is what the ODBC applet in control panel usually calls. Because you're running 32bit Oracle, you have to run the 32bit ODBC applet in order to successfully create the System DSN which can be called by PAS.
That's exactly what I need. As soon I try this I give you a feedback.
Thanks
BR
Pedro

Tables between OBAW and Oracle Data Warehouse in OBIA rpd are different

Hi,
The tables in the Data Warehouse DB is different as compared to the tables in the physical layer of the Oracle data Warehouse in OracleBIAnalytiscApps.rpd.
When I click update Row Count, it gives me below error message:
There was an error while updating row count for "Oracle Data Warehouse"."Catalog"."DBO"."W_CTRY_REGN_D":
[nQSError :17001] Oracle Error Code: 942, message: ORA-00942:Table or view does not exist at OCICallSTmTEXECUTE
Whereas when I click on some other tables for Row count there is not error.
Also, When I am trying to look for some specific table which exist in Data Warehouse (that has the data), it does not exist in the rpd.
Kindly assit me.

Oracle Data Warehouse DB and OLAP_OBIEE DB [OBIEE11g]

Hi Experts,
I have a problem regarding joining the 2 DB in an Analysis report.
The scenario is this:
Oracle Data Warehouse is DB_1 and OLAP_OBIEE is DB_2
DB_1
-col1
-col2
DB_2
-col3
In Analysis report when they are queried or run separately, obviously there will be a report generated.
But when this 2 DB columns are joined together in one Analysis report, I always get 'No Results'.
Please help how do I fix this issue :(
Thanks,

Designer Vs. Oracle Data warehouse builder

Dear all,
Currently I'm responsible of building a Data warehousing project using Oracle database. I'm trying to decide on a tool for modelling my datawarehouse. I have two options:
1) Designer: we have some experience with this tool and we are using it for our main OLTP application.
2) Oracle Data Warehouse builder: we are using this to design our ETL processes.
I want to get some advice on whether the OWB is capable of modelling my datawarehouse and of doing a retrofit action. also, I try to standardize on the tools that are using in the Data Warehouse department (currently we are using only OWB).
I will appreciate for any other advice to help in my selection process.
Best Regards,
Bilal

Hi,
In my experience this choice depends on the implementation of the datawarehouse. If you are building a "pure" Kimball style dimensional data warehouse you should be able to do this using OWB. I have architected such a DW in the past using only OWB, so I am speaking from experience.
If on the other hand you are planning to implement an Inmon style CIF, if your requirements includes an operational data store (ODS), or if you for any other reason anticipate that you are going to be doing a lot of ER modeling, then I would not recommend using the current release of OWB for modelling. (Note however that there are significant improvements to the modelling capabilities in the Paris release of OWB, so this may change in the future)
The advantage of improved maintainability when using a single tools needs to be weighted against the improved functionality if you choose a combination of the two. In the "two tool" scenario strict development and deployment routines need to be enforced to avoid that the model in Designer comes out of sync with the metadata in OWB. (Consider the effect of a developer making a change to a table definition in OWB and deploying it directly to the database without updating the model in Designer.)
Hope this helps.
Regards,
Roald

Not able to connect to Oracle Data source in Oracle Essbase Studio 11.1.2.2

Hi,
When i tried to connect to Oracle data source, i get this error "Unable to establigh connection. Ensure that the server is running, the user name and password are correct, and the ohter data fields match the server's configuration" when i tried to select database.
If i change server name from to localhost, it allows to select database and does not give any error. but clicking on next button says localhost is not accepted, it needs machine name. Then how to connect to Oracle Data source?
Edited by: User006 on Oct 10, 2012 12:45 PM

It is possible the Oracle db has not been installed correctly, I take this is a personal install on a laptop, if so did you install the loopback adaptor.
Have you tried the connection using the ip of the machine.
Cheers

Tools required to install to work with Oracle Data warehouse

Could anyone please guide me...as I am quite new to Oracle...
till now I was working on Data warehousing using Microsoft tools i.e. (SSIS, SSRS, SSAS, SQL Server)
So Please tell me which are the tools required to install to work with Oracle Data warehouse
I came to know about OWB and OBIEE, but not sure what exactly these are ?

In order to create and develop a webcenter portal application, you only need to install JDeveloper and download the WeBCenter extensions. That's true.
But this install does not include the WebCenter services like dicussions, document services, analytics,... If you want to use these and integrate them in your portal, then you would need to install the suite as described on my blog.

Error When Creating Entities From Loader Connection In Oracle Data Quality

I want to create a Loader Connection to an external data source.
I Logged on the Metabase Manager and created a new loader connection with type as 'Oracle'.
In the parameters it asked for a TNS Name.I gave the TNS of the external data source to which i want to connect from 'tnsnames.ora' file.
After that I logged on to ODQ and tried creating an Entity using create entity wizard but ODQ cannot connect to the data source using the above created Loader Connection.
It shows below failure message:
Authentication failed. couldn't load library "C:/OraHome_1/oracledq/metabase_server/lib/pkgOracleAdapter/pkgOracleAdapter.dll": could not find specified procedure
I had my ODQ metabase and ODQ GUI running on Windows.
Hope i am clear.if i am making mistake in above steps please let me know.
Waiting for reply.

How create oracle data Warehouse

hi master
sir i am use oracle 9i how i creat data Warehouse
and how use oracle portal for net
please give me idea how i start and which woftware i use
thank's
aamir

Do you want to craete a Data Warehouse database or you want to learn on how to design a Data Warehouse ?
Creating a Data Warehouse database is no different than creating an OLTP database, the only thing in mind should be is that DW are mostly read-only, so you should set initialization parameters suiting DW .

Connecting to Oracle Data Source using SSIS

Hi Guys,
Please I am working on a BI Project that requires me to connect to an oracle data source using SSIS.
Can someone assist me with the required steps to achieve that.
I dont want to use a third party tool.
Thanks
me

Hi lilutchay,
If the SQL Server Integration Services is Enterprise or Developer edition of SQL Server 2008, we can use
Microsoft Connector Version 1.2 for Oracle to connect Oracle databases with version Oracle 9.2.0.4 or higher, Oracle 10.x or Oracle 11.x. If the SQL Server Integration Services is Enterprise or Developer edition of SQL Server 2012, we can use
Microsoft Connector Version 2.0 for Oracle to connect Oracle databases with version Oracle 9.2.0.4 or higher, Oracle 10.x or Oracle 11.x.
While if we want to connect to other Oracle version databases, we can use
OLE DB provider for Oracle which has been tested in SSIS labs and is recommended by Microsoft.
For the detail steps for Microsoft Connector for Oracle, we can refer to the first blog suggested by Deric. For more details about the use of connecting to oracle using Oracle Provider for OLEDB from SSIS, please refer to the blog below:

Can latest Essbase version connect to Oracle data sources directly?

Hi
As you know in Essbase 9.3.1, you only can connect to any relational database via an ODBC data source and Essabse cannot talk to relational databases directly. Can Essbase 11.1.1 can talk to Oracle database directly or via OCI?
Chandra

Essbase Studio in 11X add jdbc connections, but there is still no "direct" connection. I'm not sure if I would want one. It would imply that Essbase is now tied directly to Oracle databases and we could lose the flexability to connect to other sources.

Recommended throughput for Oracle data warehouse

Hi, I know up front this is going to be a vague question...but I'm trying to determine approximate I/O bandwidth for a data mart server. Right now we're hosting 3 or 4 different marts on it, but that number is going to increase.
Oracle's DW "2 day" class recommends starting with either maximum throughput from user queries, or basing it off of batch windows. Right now the server is barely used for end user queries, as we haven't yet implemented a BI tool to allow users easy access (that's underway right now). So I find it hard to base any info on that. However, it's on the way, and I'm in charge of the BI took (OBIEE). I'm having nightmares that we get OBIEE deployed, and our queries end up taking 5 minutes each to get answers... Right now, on the system basically by myself, if I do a simple "select sum(amount) from fact_ledger", where fact_ledger is a 1 Gb table (with 40 million rows), it takes almost a full minute to run. It feels like I could add this up by hand and get an answer faster...and this certainly doesn't compare with other Oracle marts / DWs I've worked on in the past.
From a batch window standpoint, all I can say is that it feels really, REALLY too slow to me. Right now, some jobs that start with a 40 million row table and join it to 6 or 7 other small tables (looking up surrogate keys) and writing to a non-logged, non-indexed output table takes over 2 1/2 hours to complete. To me this should be a 15 minute job.
We've asked IT to do a "root cause analysis" of why performance is so bad - but as part of that, the architecture group wants something more concrete than "it just feels way too slow". So does anyone have some general guidelines they can provide? I guess our detailed info would be:
- three marts, each of which has a fact table around the 30 - 60 million row level
- simple "join 30 million row staging table to look up surrogate keys" and writing results is taking 2.5+ hours
- we expect at some point to have mabe 50 - 100 users running data concurrently (spread across the marts)
- users will be performance both canned and ad-hoc analysis against it...and they are high level business users, aren't going to be happy with waiting 2 minutes for a simple answer
My start was to swag this as requiring 6 CPUs or so, which would indicate (according to Oracle's best practice docs) of needing somewhere betweeen 1.2 GB/s to 2.4 GB/s throughput. I'm assuming if it takes almost a full minute to read a 1 GB table, that our IO is currently 60 to 120 times too slow. Does that make sense?
Thanks and sorry for the lack of details...we just don't know yet.
Thx,
Scott

Why don't you start by taking an AWR report from those two hours so you can see what is the bottleneck for your system ?

Connect to MS SQL Server 2000 data warehouse

Hi,
I use a MS SQL Server 2000 database for my web application where I use JSP. I suppose to create data warehouse using MS SQL Server's Data Transformation Service. But I don't know it's possible to connect to a MS SQL Server's data warehouse using JSP. So I want to know is it possible to connect to data warehouse using JSP and if it is how to do it? Thank you.

You can certainly connect to M$ SQL Server using the JDBC driver:
http://www.microsoft.com/downloads/details.aspx?FamilyID=4f8f2f01-1ed7-4c4d-8f7b-3d47969e66ae&displaylang=en
Connecting to a data warehouse is no different from any relational database. (My understanding is that a data warehouse usually means a star schema implemented in a relational database.) This will connect you.
If you're not familiar with JDBC, you might need the tutorial:

Oracle Development Survey: Data Warehouses Customers

At the start of most data warehouse projects, or even during a project, I am sure you as customers try to find answers to the following questions to help you plan and manage your environments:
* Where can I find trend and comparison information to help me plan for future growth of my data warehouse?
* How many cpu's do other customers use per terabyte?
* How many partitions are typically used in large tables? How many indexes?
* How much should I allocate for memory for buffer cache?
* How does my warehouse compare to others of similar and larger scale?
The data warehouse development team, here at Oracle would like to help provide answers to these questions. However, to do this we need your help. If you have an existing data warehouse environment, we would like to obtain more technical information about your environment(s) by running a simple measurement script and returning the output files to us, here at Oracle. This will allow our developers to provide comprehensive documents that explain best practices and get a better understanding of which features our customers use the most. This will also allow you as Customers, to benchmark your environments compared to other customers environments.
From a Company perspective we are also interested to get feedback on features we have added to the database, are these features used, how are they used etc. For example we are keen to understand:
* Which initialization parameters are most frequently used at what values?
* How many Oracle data warehouses run on RAC? on single nodes?
* Is there a trend one-way or the other, especially as data volumes increase?
* Does this change with newer releases of the database?
All results from these scripts will be held confidential. No customers will be mentioned by name; only summaries and trends will be reported (e.g., X percent of tables are partitioned and Y percent are indexed in data warehouses that are Z terabytes and larger in size. or X percent of Oracle9i and Y percent of Oracle10g data warehouses surveyed run RAC). Results will be written up as a summarized report. Every participating customer will receive a copy of the report.
Terabyte and larger DW are the primary interest, but information on any data warehouse environment is useful. We would like to have as many customers as possible submit results, ideally by the end of this week. However, this will be an on going process so regular feedback after this week is extremely useful.
To help our developers and product management team please download and run the DW measurement script kit from OTN which is available from the following link:
http://www.oracle.com/technology/products/bi/db/10g/dw_survey_0206.html
Please return the script outputs using the link shown on the above web page, see the FAQ section, or alternatively mail them directly to me: [email protected].
Thank you and we look forward to your responses.

Hi Guys, just a quick question. when we have a primary key on 4 coloumns and we have, say 20 million rows and we want to add one extra row. How does oracle check whether the data on the primary key is unique to the record being added compared to the 20 million rows. Does it actually compare the record being added to all the rows present in the table?
