Need to reset Data Warehouse

Hi,
I need to reset the Data Warehouse so that i can begin my first ETL Process. However, I'm not able to do so from DAC Client ver 7.9.5. When i click on "Tools" --> "ETL Management" --> "Reset Data Warehouse" nothing pop up's. Not sure why, all other links and windows opens, except for this. How can i get this fixed ?
Is there a way for me to do the reset manually ?
I checked on internet and found AS BELOW :-
D4 How do you run a full load (not incremental)
A: Reset data warehouse . Just truncate the S_ETL_REFRESH_DT table in the dac repository
So in our case the table to truncate will be W_ETL_REFRESH_DT rite ? Please confirm. We are scheduled to run the ETL at 6pm today.
Is there any other tables that i need to truncate as well ?
Thanks,
Saran.

Hi
W_ETL_REFRESH_DT is a metadata table on which you should never perform truncate operation.
Also,Whate 'Reset Datawareshouse' does is it just updates last_refresh_dt of w_etl_refresh_dt to NULL.
So,all you need to do is
update w_etl_refresh_dt set last_refresh_dt=NULL;
commit;
Hope this helps.......

How to reset data Warehouse table

For fixing some mistakes, I'd like to reset the whole Data Warehouse tables ( clear alll data in the tables).
Is there any way to achieve this with DAC client?
Roger

Nothing to worry. We have the option in DAC. Navigate to Tools -> ETL Management -> Reset Data Sources. Give the confirmation text in the dialog box. With this action the refresh dates will become Null for all tables and which causes to do a full load in the next ETL run.

HT201328 Error after unlocking - need to reset data settings Access Point Name

Hi -
AT&T unlocked my phone few months back. I restored the phone and got "iphone unlocked message". After inserting the new SIM card, I cannot get on the cellular network. I think I need to reset the data settings access point name. However I am unable to access this option. Can someone help?
Thanks

I had the same problem and I fixed it as following (See if it's the same case for you) :
1. Goto Tools > Options.
2. Under Advanced, select the Network Tab.
3. Click on Settings in the "Connection" box (open connection settings).
4. Check if "Automatic Proxy Configuration URL" is selected. If it is so, select "No proxy" instead or manually enter your proxy if you are using one.
The option "Automatic Proxy Configuration URL" was the culprit for me and some others as well and selecting "No proxy" instead cured our problems. It is a bug and has already been reported on Bugzilla as you can see here :

Embedded Data Warehouse

I'm in the evaluation phase of upgrading from 10.7 to 11i apps, with Advanced Supply Chain Planning. Oracle stresses in most of the documents that Business Intelligence is a key part of the planning cycle. I have seen a demo of purchasing Business intelligence and we are currently using Discoverer on a small datawarehouse, so I would like to build a case for using these tools in the new roll out. My questions are:
1. Do I need the Embedded data warehouse installed to use ASCP?
2. Do I need the Embedded data warehouse to use manufacturing and Purchasing intelligence?
3. Is Embedded Data Warehouse different than the Enterprise Data Warehouse?
thanks in advance.
t

NO.
No to all of your questions.
-- to use Discoverer against an APPS data model, you will be required to build an EUL. Which is a lot of work.
-- the "Intelligence" package contains that EUL that you need, so if you buy the intelligence module you will get that. And as a bonus you get the E-DW which is the "ENTERPRISE" or "EMBEDDED" database. same product.
But remember, intelligence modules are costy $$$
good luck!

Building a data warehouse

Good Morning Buddys,
Actually I need build a data warehouse and I've some doubts:
1. OLTP I have these tables (Adventureworks):
Production.Location
LocationID int primary key
Name nvarchar(50)
CostRate smallmoney
Availability decimal(8,2)
ModifiedDate datetime
LocationFK int -- example
Production.ProductCategory
ProductCategoryID int primary key
Name nvarchar(50)
rowguid uniqueidentifier
ModifiedDate datetime
ProductCategoryFK int -- example
Production.ProductModel
ProductModelID int primary key
Name nvarchar(50)
CatalogDescription xml
Instructions xml
rowguid uniqueidentifier
ModifiedDate datetime
ProductModelFK int -- example
When I transfer to Staging is necessary I have foreign key columns? I mean with varchar, not int (foreign key) for example:
STAGING_Production.Location
LocationID varchar(20)
Name nvarchar(50)
CostRate varchar(20)
Availability varchar(20)
ModifiedDate varchar(20)
LocationFK varchar(20) - it's correct?
STAGING_Production.ProductCategory
ProductCategoryID varchar(20)
Name nvarchar(50)
rowguid varchar(20)
ModifiedDate varchar(20)
ProductCategoryFK varchar(20) - it's correct?
I've no idea if is necessary foreign key columns transfer to staging but with another data type...
some one can help me please?

Ok ok
following:

Why do we need SSIS and star schema of Data Warehouse?

If SSAS in MOLAP mode stores data, what is the application of SSIS and why do we need a Data Warehouse and the ETL process of SSIS?
I have a SQL Server OLTP database. I am using SSIS to transfer my SQL Server data from OLTP database to a Data Warehouse database that contains fact and dimension tables.
After that I want to create cubes using SSAS form Data Warehouse data.
I know that MOLAP stores data. Do I need any Data warehouse with Fact and Dimension tables?
Is not it better to avoid creating Data warehouse and create cubes directly from OLTP database?

Another thing to note is data stored in transactional system may not always be in end user consumable format for ex. we may use bit fields/flags to represent some details in OLTP as storage required ius minimum but presenting them as is would not make any
sense to user as they would not know what each bit value represents. In such cases we apply some transformations and convert data into useful information for users to understand. This is also in the warehouse so that information in warehouse can directly be
used for reporting. Also in many cases the report will merge data from multiple source systems so merging it on the fly in report would be tedious and would have hit on report server. In comparison bringing them onto common layer (warehouse) and prebuilding
aggregates would be benefitial for the report performance.
I think (not sure) we join tables in SSAS queries and calculate aggregations in it.
I think SSAS stores these values and joined tables and we do not need to evaluates those values again and this behavior is like a Data Warehouse.
Is not it?
So if I do not need historical data, Can I avoid creating Data Warehouse?
On the backend SSAS uses queries only to extract the data
B/w I was not explaining on SSAS. I was explaining on what happens inside datawarehouse which is a relational database by itself. SSAS is used to built cube (OLAP structures) on top of datawarehouse. star schema is easier for defining relationships
and buidling aggregations inside SSAS as its simple and requires minimal lookups to be performed. Also data would be held at lowest granularity level which can easily be aggregated to required levels inside OLAP cubes. Cube processing is very resource
intensive and using OLTP system would really have a huge impact on processing performance as its nnot denormalized and also doing tranformation etc on the fly adds up to complexity. Precreating a layer (data warehouse) having data in required format would
make cube processing easier and simpler as it has to just cross join tables and aggregate data based on relationships defined and level needed inside the cube.

Does TV Shows show as a category under the Purchased link under Quicklinks on the right-hand side of the iTunes store homepage on your Mac's iTunes ? If it does, and that series is still in your country's store, then it should show there and you can download it from there (click the cloud icons) onto your Mac's iTunes library - you can then sync the episodes to your phone.

Needs daily reset when cellular data off

When I am using the ipone with cellular data turned off, the telephone function freezes every second day. I need to reset the iphone. Genius bar has told me that this is not an apple issue. The network provider (SoftBank Japan) has told me it is not their problem, but that if I switch on cellular data every day it will go away. Haha!!!!! Anyone elsewhere have the same issue? This is a major issue as I am paying an extra $7 a month for a variable tariff!

Yes, that is normal. The signal bars still show because the iPhone can make calls and send SMS, which still requires connectivity. iPad has neither of these, so once cellular data is turned off, it doesn't need the cellular network for anything.

Rebuilding/Reseting the SCOM 2012 SP1 Data Warehouse. What is the easiest way and what steps i have to perform

Hello guys,
What are the best steps to rebuild the data warehouse ? In SCOM 2012 SP1 it is build during the initial installation and SCOM it is not giving you a tool to rebuild it. I have tried to create one DW database using the Data Warehouse Initial Setup.sql file
from the installation dvd and copied the permissions from my original DW. Although the sql script executed successfully i found some missing tables in the newly created database. So I'm not sure whether if i detach the old DW and rename the new test database
to OperatonsMangerDW it will work. Please advice on this issue. Please let me know if there is any easier approach of rebuilding/resetting the Data Warehouse database.

Hi,
I would like to suggest you refer to the below link to move the data warehouse database to a different system:

Do I need Management Data Warehouse for SAP on SQL?

Hi experts,
I am reading Jonathan Kehayias's wait statistics guide and I see he talk about Management Data Warehouse. Should I use Management Data Warehouse in SAP on SQL environment? I see many monitor objects are already implemented in DBACockpit.

Hi Dennis,
In case you have your SAP system on MSSQL, you can definitely use Management Data warehouse
to streamline performance troubleshooting.

Data Warehouse issues

Hi there.
I'll try and be to the point as I can. I undertook an upgrade from SCOM 2012 SP1 to R2, this was successful. However after a few days had past, I noticed that the log file for the DW DB was growing rapidly, to the point where we hit a real issue. The drive
was a comfortable 50GB drive, but in the end had to be increased to just short of 500GB !! Long story short, I wasn't allowed to get a consultant in to help diagnose the issue, therefore, I was consulting Google, Technet articles etc.
The end decision was to DELETE the Data Warehouse DB & log file and create them again from scratch. I've done this, and used the following instructions on how to do so (http://www.3packetsofcrisps.com/2014/04/reset-scom-2012-data-warehouse-database.html).
I have data going into the DW DB, or rather did up until midnight, so had around 3.5 hrs worth.
After checking the Operations Manager event log on one of the Management Servers, I can see numerous errors, these include:2115, 4506 and occasionally 8000.
The event 4506 states: "Data was dropped due to too much outstanding data in rule "Rule Name" running for instance "instance name" with id "ID name" in management group "xxx".
After some consulting Google, I read that this might be expected because a lot of data is trying to be written to the DW DB, however, that doesn't explain why it was writing and for some reason randomly stopped.
A quick summary of our environment:
2x Management Servers running Win 2012 Std x64
1x Operations Database server running Win 2012 Std x64 & SQL Server 2012 Std x64
1x Data Warehosue DB server running Win 2012 Std x64 & SQL Server 2012 Std x64
I've checked account permissions using http://technet.microsoft.com/en-gb/library/hh457003.aspx
If you need any more information, please say, I've tried to keep the post as small as possible.
Dave.

Hi
Thanks for responding. It's been over a day so far, however, I've only just flushed the health service state & cache for the servers I'm monitoring. Would you suggest I do this for the Management Servers as well?
In regards to alerts in the SCOM console, I am getting active alerts. I've just checked and some were 49 minutes ago.
I've also taken another look at the DW DB (via Windows Explorer), and I can see the last modified date has changed to 09/09/2014 20:48. So once again, something has happened but it appears to be random..
This might need to be a separate post, but I've also got issues with my Reporting. If I go to the 'Reporting Server URL', I get the following message: "The version of the report server database is either in a format that is not valid, or it cannot
be read. The found version is ''. The expected version is '162'. (rsInvalidReportServerDatabase)"
Any ideas?
Dave

Best practice of metadata table in data warehouse environment ?

Hi guru's,
In datawarehouse, we have 1. Stage schema 2. DWH(Data warehouse reporting schema). In stageing we have about 300 source tables. In DWH schema, we are creating the tables which are only required from reporting prespective . some of the tables in stageing schema, have been created in DWH schema as well with different table name and column names. The naming convention for these same tables and columns in DWH schema is more based on business names.
In order to keep track of these tables we are creating metadata table in DWH schema say for example
Stage                DWH_schema
Table_1             Table_A
Table_2             Table_b
Table_3             Table_c
Table_4              Table_DMy question is how do we handle the column names in each of these tables. The stage_1, stage_2 and stage_3 column names have been renamed in DWH_schema which are part of Table_A, Table_B, Table_c.
As said earlier, we have about 300 tables in stage and may be around 200 tables in DWH schema. Lot of the column names have been renamed in DWH schema from stage tables. In some of the tables we have 200 column's
so my concern is how do we handle the column names in metadata table ? Do we need to keep only table names in metadata table not column names ?
Any idea will be greatly appriciated.
Thanks!

hi
seems quite a buzzing question.
In our project we designed a hub and spoke like architecture.
Thus we have 3 layer, L0 is the one closest to the source and L0 table's name are linked to the corresponding sources names by mean of naming standard (like tabA EXT_tabA tabA_OK1 so on based on implementation of load procedures).
At L1 we have the ODS , normalized model , we use business names for table there and standard names for temporary structures and artifacts
Both L0 an L1 keep source's column names as general rule, new columns like calculated one are business driven and metadata are standard driven.
Datamodeler fits perfect for modelling L1 purpose.
L2 is the dimensional schema business names take place for tables and columns eventually rewritten at presentation layer ( front end tool )
hope this helps D.
