Book on Oracle Data warehousing for DBAs

Hi,
Please suggest some book regarding the Oracle data warehouse from the DBA perspective. As how to physically implement the database, scenarios, partitioning, parrallelism etc. Please also suggest some blogs or articles in that regard.
Thanks and regards

A good place to start for well-written and properly researched articles is Mark Rittman's blog: http://www.rittmanmead.com/blog/ although it's bias may be a little too much towards the BI side of data warehousing for your requirements.

Oracle Enterprise Data Quality certification

Any one have Oracle Data Quality certification dumps . I need it urgently. Please send me at < email address deleted by moderator > . Thank you in advance.

Moderator Action:
Thread locked. Email address removed from the original post.
Test dumps are illegal. They consist of material stolen from Oracle.
Requesting someone to do an illegal thing is just plain wrong.
Anyone proven to have used dumps to prepare for tests makes them liable to have ALL their certifications revoked and that person banned from future testing.

Will Oracle ever create a Data Guard certification?

Will Oracle ever create a Data Guard Certification?
If so would it be more of a "HA" - high availability,
or would it be only about Active Data Guard.
Thanks

We have a Data Guard Admin certification coming soon. Unfortunately, I don't have a closer date than that.

Data Owner Certification in Oracle identity analytics

Hi all,
I am trying to do data owner certification in OIA.
Certification is getting completed 100%. But, the remediation is not working.
I have applied the BP4 patch also.
Steps followed for the data owner certification:*
1)In identity certification, selected new certification--> Type:Data Owner.
2)Selection Strategy: By Data Owner
3)Added the data owners and clicked next.
4)Selected the certifier as data owner and created the certificate.
5)I logged in as the certifier and opened the certificate.
6)Chose 'does not belong to me' and completed the certificate.
When i checked the status in remediation tracking, it shows that the certificate is complete.
But, the attribute is not revoked.
Please let me know if something is missing in my procedure.
Regards,
Narmadha.

Hi Narmadha,
The first screen of the certification will show all the 'attributes' that belong to the Data owner. Accordingly you can 'claim' them.After claiming them, you can examine the users who have the attributes that you claimed for. Over here you can perform certify/revoke/ etc.. for the users. Once the certification is complete, you can view the result from two places. you can view the report from clicking the completed certification and from the Reports Tab. Once you are in reports Tab, go to sign-off reports and navigate to completed reports sub-tab. There you will see all the reports generated for completed certifications.

1Z0-515 exam Data Warehousing 11g Essentials

Hi,
I want to know if this new training
Oracle Database 11g: Administer a Data Warehouse
sufficient to prepare for that exam or we need additional training or book (beside documentation off course) ?
If I am not working with an OPN company, what title that I will get after passing the exam?
thanks

One additional clarification. You do not have to be working for an OPN company in order to obtain this certification. Anyone can take the exam and pursue this certification and will receive the credential Data Warehousing 11g Certified Implementation Specialist. Those working for an OPN company will receive the additional designation of Oracle PartnerNetwork Certified Specialist.
Regarding training, the OU course that has been identified that has been identified to best help candidates prepare for the exam is 'Oracle Database 11g: Data Warehousing Fundamentals'
http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getCourseDesc?dc=D56261GC10
This information will be released on the website in a couple of weeks.

Should I use olap plus package in my data warehousing project?

I will build a massive data warehousing which size is over 3t.
And I will provide many analytical functions to users.
Oracle 11g is my choice. But OLAP is suitable for me, I don't know?
In my opinion, OLAP is helpful to analysis, but it's hard to refresh data when it's based on a large table.
Who can help me? Thanks.

So as I'm attempting to do the first one of these, I'm feeling like I should have gone with iMovie. Why? Because everything except for the green screen can be done so easily and with profressional looking results in iMovie. But that just doesn't seem right to me.< </div>
It takes thick skin to be in this business so I'll test that ability of yours now: Your statements imply vast gaps in your skills, knowledge and patience. That's not bad, we all got started someplace, but you're in way over your head.
We'll help in any way we can. I'll start by telling you to forget the notion that HD is necessary if your release media are iPods and Flash.

Best Course for Data Warehousing

Hi,
I am planning to join data warehousing course .I heard there is lot courses in data warehousing .
Data warehousing with ETL tools or
Data warehousing with Crystal Reports or
Data warehousing with Business object or
Data warehousing with Informatica or
Data warehousing with Bo-Webel or
Data warehousing with Cognos or
Data warehousing with Data Stage or
Data warehousing with MSTR or
Data warehousing with Erwin or
Data warehousing with oracle.
Please suggest me which best to choose and which have more scope because I don't know the ABC of data warehousing but I have some experience in oracle.
Is it must that I need work experience in data warehousing then only can get a job ?Please tell me which is the best book for data warehousing which should start from scratch. Please give your suggestions about to my queries.
Thanks & Regards,
Raji

Hi,
Basically Datawarehouse is a concept.To develop DW , we need two tools mainly. One is ETL tool and other one is Reporting tool .
The few famous ETL tools are
Informatica
Data Stage
Few famous Reporting tools are
Crystal Reports
Cognos
Business object
As a DW developer you should aware of atleat one ETL tool and atleat one Reporting tool.The combination is your choice.It better to finout the best combination in point of job market , and then learn them.
Erwin is Datamodel tool. It can aslo be used in DW implementation. You have already have experience on ORacle,So my adivce is go for Data warehousing with oracle or Data warehousing with Informatica .And learn one reporting tool.I donot is there any reporting tool available from ORACLE.
My suggestion on books.
Fundamentals of Datawarehouse by PaulRaj Ponnai and
Datawarehouse toolkit.
http://www.inmoncif.com/about.html is one of the best site for Datawarehouse.
With rgds,
Anil Kumar Sharma .P
Assigning points is the way to say thanks in SDN site.

Scope for data warehousing ETL Tool

Hi all
can anybody explain scope for data warehousing ETL Tool
for oracle developer in future this is ok or..
regards
Message was edited by:

What exactly is your question?
The scope of using an ETL tool would be setting up and maintaining datawarehouses and building ETL processes to populate these datawarehouses.
A tool is generally preferred over hand coding because tools allow better maintenance, shorter development cycles etc.
Oracle has a pretty good ETL tool, called Oracle Warehouse Builder. It's not the best tool available, but if you compare price/ functionality I would say in most cases it will do.
If your question is if it's a wise pick to master OWB or any ETL tool my answer would be a clear YES! Datawarehouses and BI are becoming more important every day, their use gets broader everyday.
If your question is if an investment in OWB is a wise investment for the future I would answer a clear YES again. It's increddilbe to see what progress Oracle made with the tool, coming from a 'laughing stock' postition, regarded completely immature good for nothing tool, to where they are now, with 10.2. Regarded as one of the leaders by Gartner.
Oracle has recognized (a long while ago) that ETL is the bread and butter of the future and invests in a good quality tool for accomplishing this.
I hope this answes your question, if not, please try to specify more clearly.
Regards,
Toin.
