SQL scripts for Data Warehouse support team

Hi, I would like to have the SQL scripts that must be there with a person supporting a data warehousing system... like on locks, sessions, how much progress a transaction/SQL has made, resources being consumed.

There are various scripts available on the net. For example http://www.oracle-base.com/dba/DBACategories.php

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:
http://java.sun.com/docs/books/tutorial/jdbc/

Are there any timesten installation for data warehouse environment?

Hi,
I wonder if there is a way to install timesten as an in memory database for data warehouse environment?
The DW today consist of a large Oralcle database and I wonder if and how a timesten implementation can be done.
what kind of application changes involve with such an implementation and so on?
I know that the answer is probably complex but if anyone knows about such an implementation and some information about it , it would be great to learn from that experience.
Thanks,
Adi

Adi,
It depends on what you want to do with the data in the TimesTen database. If you know the "hot" dataset that you want to cache in TimesTen, you can use Cache Connect to Oracle to cache a subset of your Oracle tables into TimesTen. The key is to figure out what queries you want to run and see if the queries are supported in TimesTen.
Assuming you know the dataset you need to cache and you have control of your application code to change the connection to TimesTen (using ODBC or JDBC), you can give it a try. If you are using a third party tool, you need to see if the tool supports JDBC or ODBC access to the database and change the tool to point to your TimesTen database instead of the Oracle database.
If you are using the TimesTen Cache Connect to Oracle product option, data synchronization between Oracle and TimesTen is handled automatically by the product.
Without further details of what you'd like to do, it's difficult to provide more detailed recommendation.

Data Access Object for Data Warehouse?

Hi,
Does anyone know how the DAO pattern looks like when it is used for a data warehouse rather than a normal transactional database?
Normally we have something like CustomerDAO or ProductDAO in the DAO pattern, but for data warehouse applications, JOINs are used and multiple tables are queried, for example, a query may contains data from the Customer, Product and Time table, what should the DAO class be named? CustomerProductTimeDAO?? Any difference in other parts of the pattern?
Thanks in advance.
SK

In my opinion, there are no differences in the Data Access Object design pattern which have any thing to do with any characteristic of its implementation or the storage format of the data the pattern is designed to function with.
The core pupose of the DAO design pattern is to encapsulate data access code and separate it from the business logic code of the application. A DAO implementation might vary from application to application. The design pattern does not specify any implementation details. A DAO implementation can be applied to group of XML data files, an Excel-based CSV file, a relational database, or an OS file system. The design is the same for all these, it is the implementation that varies.
The core difference between an operational database and a strategic data warehouse is the purpose of why and how the data is used. It is not so much a technical difference. The relational design may vary however, there may be more tables amd ternary relationships in a data warehouse to support more fine-tuned queries; there may be less tables in a operational database to support insert/add efficiencies.
The DAO implementation for a data warehouse would be based on the model of the databases. However the tables are set up, that is how the DAO is coded.

Are analytic functions usefull only for data warehouses?

Hi,
I deal with reporting queries on Oracle databases but I don't work on Data Warehouses, thus I'd like to know if learning to use analytic functions (sql for anaylis such as rollup, cube, grouping, ...) might be usefull in helping me to develop better reports or if analytic functions are usually usefull only for data warehouses queries. I mean are rollup, cube, grouping, ... usefull also on operational database or do they make sense only on DWH?
Thanks!

Mark1970 wrote:
thus does it worth learning them for improving report queries also not on DHW but on common operational databases?Why pigeonhole report queries as "+operational+" or "+data warehouse+"?
Do you tell a user/manager that "<i>No, this report cannot be done as it looks like a data warehouse report and we have an operational database!</i>"?
Data processing and data reporting requirements not not care what label you assign to your database.
Simple real world example of using analytical queries on a non warehouse. We supply data to an external system via XML. They require that we limit the number of parent entities per XML file we supply. E.g. 100 customer elements (together with all their child elements) per file. Analytical SQL enables this to be done by creating "buckets" that can only contain 100 parent elements at a time. Complete process is SQL driven - no slow-by-slow row by row processing in PL/SQL using nested cursor loops and silly approaches like that.
Analytical SQL is a tool in the developer toolbox. It would be unwise to remove it from the toolbox, thinking that it is not applicable and won't be needed for the work that's to be done.

An error occurred while applying SQL script for the feature BackendStore.

Hello,
I am using my AD in Windows Azure VMs. I created new VM of A3 (4 cores, 7 GB Memory) Windows Server 2012 R2, Port 1433 MSSQL added, made it a member of Domain and planned to install first Lync Server 2013 on it.
In "Setup or Remove Lync Server Components" of "Install or Update Lync Server System", got an Red Coloured text "An error
occurred while applying SQL script for the feature BackendStore."
I have not enabled monitoring and archiving server in topology builder. I added "Network Service" and assign "Full Control" in Security Permissions of "C:\CsData" and "C:\LyncShare".
I executed the SQL Setup Wizard and upgraded any instance to 2012.
Please guide.

Using CVS in SQL Developer for Data Modeler changes.

Hi,
I am fairly new to SQL Developer Data Modeler and associated version control mechanisms.
I am prototyping the storage of database designs and version control for the same, using the Data Modeler within SQL Developer. I have SQL Developer version 3.1.07.42 and I have also installed the CVS extension.
I can connect to our CVS server through sspi protocol and external CVS executable and am able to check out modules.
Below is the scenario where I am facing some issue:
I open the design from the checked out module and make changes and save it. In the File navigator, I look for the files that have been modified or added newly.
This behaves rather inconsistently in the sense that even after clicking on refresh button, sometimes it does not get refreshed. Next I try to look for the changes in Pending Changes(CVS) window. According to the other posts, I am supposed to look at the View - Data Modeler - Pending Changes window for data modeler changes but that shows up empty always( I am not sure if it is only tied to Subversion). But I do see the modified files/ files to be added to CVS under Versioning - CVS - Pending Changes window. The issue is that when I click on the refresh button in the window, all the files just vanish and all the counts show 0. Strangely if I go to Tools - Preferences - Versioning - CVS and just click OK, the pending changes window gets populated again( the counts are inconsistent at times).
I believe this issue is fixed and should work correctly in 3.1.07.42 but it does not seem to be case.
Also, I m not sure if I can use this CVS functionality available in SQL Dev for data modeler or should I be using an external client such as Wincvs for check in/ check out.
Please help.
Thanks

Hi Joop,
I think you will find that in Data Modeler's Physical Model tree the same icons are used for temporary Tables and Materialized Views as in SQL Developer.

RMAN crosscheck and expire guidelines for data warehouse environment

O/S: Windows Server 2008
DB: Oracle 11gR2
Are there any guidelines to how often one should do a RMAN crosscheck and set an expiration on archivelogs for data warehouse environments?
It would seem once a day would be enough for the crosscheck in a data warehouse environment that gets refreshed nightly. Expiration I would expect no less than 1 week.
Cheers!

RAC for Data Warehouse

Hello,
We have a research project for restructructuring our data warehouse system.
I would like to get some opinions about whether RAC architecture can be
a good solution for Data Warehouse application.
We have using parallel queries massively. Does running these kind of queries
on different servers on RAC with multiple server result in performance degradation rather than
running on single monolithic server with multiple CPUs
I will appreciate any comments using RAC architecture for Data Warehouse
systems?
Regards,

Just keep in mind that during the last 4 years (I guess your current system is about 4 years old) the CPUs became much faster.
A cpu can't work without data which means that the I throughput has to be fast enough to feed all your cores with data.
The main bottleneck of all DWHs I have seen during the last 8 years was allways the IO never the CPUs. And not just data warehousing Maurice, but a basic principle for any data processing platform - the slowest layer is always the I/O layer.. and can be the most expensive one to solve too.
Which is why newer technology like Infiniband is exciting as it can also serve as the I/O layer. Instead of using the traditional HBA which is typically configured with 2Gb fibre channels to the storage layer, using HCA cards you can wire this directly into an Infiniband storage array... and this can run at up to speeds of 40Gb. Dual connections means a total theoretical pipe size of 80Gb. I do not know of any other standard technology (like GigE) that can provide any similar bandwidth speed.
Back to RAC though - with RAC, when you add a new server that comes with a new set of I/O pipes.. plus of course more RAM and more CPU cores. SMP server architecture does not scale like this at all. You only have x number of slots for PCI cards, CPUs and RAM. A very specific ceiling that cannot be moved. With MPP this ceiling is a a lot higher and more flexible.
You can also replace a dual core dual CPU nodes with a 6 core AMD Istanbul CPUs next year.. and possibly 12 core CPUs year after that. So even a smallish 4 node cluster with 16 cores in total can be grown significantly and remain a 4 node cluster. Together with advances in HPC (High Performance Computing) like Infiniband.
I'm not seeing much use of non-RAC RDBMS architecture in the future. Databases are getting ever bigger because we have the technology to crunch more data, and crunch it a lot more intelligently than ever before. My first production database was 4MB in size, and ran on a Novell File Server with two 20MB disks. I'm currently testing a 24TB array for use for a single database.
Technology is inevitable, as is the growth in data volumes. And I cannot see a non-RAC architecture rising to that challenge. Especially not in something like data warehousing.

SQL Server Parallel Data Warehouse (PDW) Licensing

Hi All,
We have a customer that's interested in SQL Server Parallel Data Warehouse
(PDW). I'm told this is an appliance sold by a manufacturer like Dell or HP. But
I also see Licensing price on the EA price list.
Can they also purchase PDW under a VL Agreement?
Regards,
DSarao

Yes. Microsoft sells PDW as an appliance with a software and hardware purchase. Note that the PDW requires both the software and hardware purchase.

OBE for Data Warehouse 9.2

Dear All
Can anyone tell me the link of Oracle By Example: Hands on Tutorials for Data Warehouse 9.2.
I have found Oracle By Example: Hands On Tutorials Data Warehouse OWB 10g release 1, 10g release 2 and 11g at the following link

Thanks in Advance.

Dear Dallan
I was looking for the Oracle By Example sort of tutorials for OWB 9.2.
Actually I want to learn OWB form 9.2 to 10.2. I have OWB 10.1 and OWB 10.2,
what missing was OWB 9.2.
That's why I have put it on forum so that anyone who knows where they can guide me.
But your comment that there is a little difference in OWB 9.2 and OWB 10.1, if I won't get
OWB 9.2 then it's better to start with OWB 10.1.
Ayway Thanks.
