Data warehouse configuration doubt
Hi guys,
I´m studing data warehouse and I would like to know if there´s any documentation showing the correct way to configure a DW database, like parameters, block size and partitioned tables.
or if you have experience please post here your suggestions.
Thank you,
Felipe
Starting with Oracle's data Warehousing Guide, documentation is a great start.
http://download-uk.oracle.com/docs/cd/B10501_01/server.920/a96520/toc.htm
You can also search fro datawarehouse books from goole or any search enginee.

What are the best solutions for data warehouse configuration in 10gR2
I need help on solutions to be provided to my Client for upgrading the data warehouse.
Current Configuration: Oracle database 9.2.0.8. This database contains the data warehouse and one more data mart on the same host.Sizes are respectively 6 Terabyte(retention policy of 3 years+current year) and 1 Terabyte. The ETL tool and BO Reporting tools are also hosted on the same host. This current configuration is really performing poor.
Client cannot go for a major architectural or configuration changes to its existing environment now due to some constraints.
However, they have agreed to separate out the databases on separate hosts from the ETL tools and BO objects. Also we are planning to upgrade the database to 10gR2 to attain stability, better performance and overcome current headaches.
We cannot upgrade the database to 11g as the BO is at a version 6.5 which isn't compatible with Oracle 11g. And Client cannot afford to upgrade anything else other than the database.
So, my role is very vital in providing a perfect solution towards better performance and take a successful migration of Oracle Database from one host to another (similar platform and OS) in addition to upgrade.
I have till now thought of the following:
Move the Oracle database and data mart to separate host.
The host will be the same platform, that is, HP Superdome with HP-UX 32-bit OS (we cannot change to 64-bit as ETL tool doesn't support)
Install new Oracle database 10g on the new host and move the data to it.
Exploring all new features of 10gR2 to help data warehouse, that is, SQL MODEL Clause introduction, Parallel processing, Partitioning, Data Pump, SPA to study pre and post migrations.
Also thinking of RAC to provide more better solution as our main motive is to show a tremendous performance enhancement.
I need all your help to prepare a good road map for my assignment. Please suggest.
Thanks,

Also I am pasting part of STATSPACK Report, eliminating the snaps of DB bounce. Please suggest the scope of improvement in this case.

EXTRACTing to TEXT file in Data Warehouse - Simple doubts!
Hi Experts,
Pls. clarify my simple doubts, in data EXTRACTing prog.,(data extract from SAP to text file in Application server, prog. runs in back ground)
For the Dataware house mapping, I hv been asked to make the following changes,
1) Presently, there is NO column headings in Text file, so I need to add the column Headings - How to get it done?
2) presently, its NOT tab deliminated, so, I need to make it to TAB deliminated- How to achieve it?
I am here paste some piece of code, so that U will get understand well.
PERFORM open_dataset_zdata_whouse_04.
DESCRIBE FIELD i_tab LENGTH tfr_length IN BYTE MODE.
LOOP AT i_itab.
TRANSFER i_itab TO transfer_file1 LENGTH tfr_length.
ENDLOOP.
CLOSE DATASET transfer_file1.
ThaNQ.See the below code :
parameters: d1 type localfile default
'/usr/sap/TST/SYS/Test.txt'.
data: begin of itab occurs 0,
field1(20) type c,
field2(20) type c,
field3(20) type c,
end of itab.
data: str type string.
constants: con_tab type x value '09'.
if you have a newer version, then you can use this
instead.
*constants:
con_tab type c value
cl_abap_char_utilities=>HORIZONTAL_TAB.
start-of-selection.
itab-field1 = 'ABC'.
itab-field2 = 'DEF'.
itab-field3 = 'GHI'.
append itab.
itab-field1 = '123'.
itab-field2 = '456'.
itab-field3 = '789'.
append itab.
open dataset d1 for output in text mode.
loop at itab.
translate itab using ' # '.
concatenate itab-field1 itab-field2 itab-field2
into str
separated by con_tab.
translate str using ' # '.
transfer str to d1.
endloop.
close dataset d1.
above code for tab delimited.
for heading then you can write simple logic in the loop of internal table
loop at itab.
if sy-tabix = 1'
move heading data to file.
endif.
endloop.
Thanks

How to create a new data warehouse?
Hi,
I have a set up where multiple SCOM management groups all report to a shared data warehouse database. For various reasons, we need to “unplug” the management groups from this shared resource and give them each their own data warehouse to use (locally, rather
than centrally).
Is there a way of creating a new clean data warehouse without running a full installation? I’m imagined that I could probably put a copy of the existing shared one into each local management group and then use this process (http://technet.microsoft.com/EN-US/library/hh268492.aspx)
to repoint each locally – but it would be nicer to start fresh for each one. Is that possible, is there an installation I can run for JUST the DW elements of the SCOM installation?
Thanks.Breaking a shared data warehouse configuration into separate data warehouses is really not supported - there is no installation path for this and no guidance available. If you absolutely need to do this, then you are basically stuck with reinstalling the
data warehouse and reporting server for each management group. You will lose all historical reporting in this scenario. Sure, the data can be saved and used elsewhere, but it will not be available as you would expect to see it in the reporting space of the
Operations Console.
Moving the data warehouse as Mai suggested will not solve the problem, and may actually end up in in other problems with retention and reports being unavailable for some instances. I would not suggest moving/copying the existing data warehouse to each management
group.

Configuration Dataset = 90% of Data Warehouse - Event Errors 31552
Hi All,
I'm currently running SCOM 2012 R2 and have recently had some problems with the Data Warehouse Data Sync. We currently have around 800 servers in our production environment, no Network devices, we use Orchestrator for integration with our call logging system
and I believe this is where our problems started. We had a runbook which got itself into a loop and was constantly updating alerts, it also contributed to a large number of state changes. We have resolved that problem now, but I started to receive alerts
saying SCOM couldn't sync Alert data under event 31552.
Failed to store data in the Data Warehouse.
Exception 'SqlException': Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
One or more workflows were affected by this.
Workflow name: Microsoft.SystemCenter.DataWarehouse.StandardDataSetMaintenance
Instance name: Alert data set
Instance ID: XX
Management group: XX
I have been researching problems with syncing alert data, and came across the queries to manually do the database maintenance, I ran that on the alert instance and it took around 16.5 hours to run on the first night, then it ran fast (2 seconds) most the
day, when it got to about the same time the next day it took another 9.5 hours to run so I'm not sure why that's giving different results.
Initially it appeared all of our datasets were out of sync, after the first night all appear to be in sync bar the Hourly Performance Dataset. Which still has around 161 OutstandingAggregations. When I run the Maintenance on Performance it doesn't appear
to be fixing it. (It runs in about 2 seconds, successfully)
I recently ran DWDatarp on the database to see how the Alert Dataset was looking and to my surprise I found that the Configuration Dataset has blown out to take up 90% of the DataWarehouse, table below. Does anyone have any ideas on what might cause this
or how I can fix it?

which from my readings means I'm likely in for an MS support call.. :( But I just wanted to see if anyone has any information about the Configuration Dataset as I couldn't find much in my searching.Hi All,
The results of the MS Support call were as follows, I don't recommend doing these steps without an MS Support case, any damage you do is your own fault these particular actions resolved our problems:
1. Regarding the Configuration Dataset being so large.
This was caused by our AlertStage table which was also very large, we truncated the alert stage table and ran the maintenance tasks manually to clear this up. As I didn't require any of the alerts sitting in the AlertStage table we simply did a straight truncation
of the the table. The document linked by MHG above shows the process of doing a backup & restore on the AlertStage Table if you need to. It took a few days of running maintenance tasks to resolve this problem properly. As soon as the truncation had taken
place the Confirguration Dataset dropped in size to less than a gig.
2. Error 31553 Duplicate Key Error
This was a problem with duplicate keys in the ManagedEntityProperty table. We identified rows which had duplicate information, which could be gathered from the Events being logged on the Management Server.
We then updated a few of these rows to have a slightly different time to what was already in the Database. We noticed that the event kept logging with a different row each time we updated the previous row. We ran the following query to find out how many rows
actually had duplicates:
select * from ManagedEntityProperty mep
inner join ManagedEntity me on mep.ManagedEntityRowId = me.ManagedEntityRowId
inner join ManagedEntityStage mes on mes.ManagedEntityGuid = me.ManagedEntityGuid
where mes.ChangeDateTime = mep.FromDateTime
order by mep.ManagedEntityRowId
This returned over 25,000 duplicate rows. Rather than replace the times for all the rows, we removed all duplicates from the database. (Best to have MS Check this one out for you if you have a lot of data)
After doing this there was a lot of data moving around the Staging tables (I assume from the management server that couldn't communicate properly), so once again we truncated the AlertStage table as it wasn't keeping up. Once this was done everything worked
properly and all the queues stayed under control.
To confirm things had been cleared up we checked the AlertStage table had no entries and the ManagedEntityStage table had no entries. We also confirmed that the 31553 events stopped on the Management server.
Hopefully this can help someone, or provide a bit more information on these problems. -
Service Manager Data Warehouse Install - Analysis Server Configuration For OLAP Cubes Fail
Hello everyone,
I have an issue with my installation of the Data Warehouse for System Center Service Manager 2012 SP1.
My install environment is the following:
Windows Server 2012 – System Center Service Manager (Successfully Installed) - Virtual
Windows Server 2012 – System Center Data Warehouse (Pending) - Virtual
Windows Server 2012 – MS SQL Server 2012 – Physical, Clustered 1<sup>st</sup> of Four Servers
The SQL Server is a clustered installation with named instances, specifically for SharePoint and Service Manager. Each instance has its own IP address and dynamic ports are turned off. I’m installing using the domain administrator account and I also chose
to run the installer as administrator. The domain admin has sysadmin rights to the service manager server and instance I’m trying to install on. However, the account does not have sysadmin rights to some of the other instances.
The install is smooth up until it needs to connect to the Analysis server database. I have tried connecting to the analysis servers on other SQL servers on site and all were successful. The only difference between the older SQL servers, the SQL 2012 development
server and the SQL 2012 Production server I’m trying to install to is that the that the domain admin account doesn’t have sysadmin access on all the databases on the new production server. The SQL server is being installed and configured by a contractor so
if you all have troubleshooting suggestions, I’ll need to coordinate with the contractor.
Starting with the screen below, I began searching for help online. There seems to be no one else with this issue or it is not documented properly. I opened a ticket with MS, called the contractor and troubleshot with him, troubleshot as far as I could on
my own and I’m still at a loss as to what is preventing the installer from connecting specifically to the analysis server.
I first thought the installer was at issue or that the data warehouse sever was at issue. But all signs are pointing at the SQL server. The installer is able to connect to all the other SQL servers – including other 2012 servers (same versions) – so it can’t
be the installer. I’m pretty sure the SQL server is going to be at issue.
After looking at this error, I opened the resource monitor and clicked the dropdown to see if it was trying to connect to the correct server and it was. I then connected to the old and new test and development servers successfully. Then connected to the
SQL 2008 R2 production cluster successfully. I then compared the two servers. The only difference other than the version numbers is that the admin account doesn’t have sysadmin rights on all the SQL 2012 database servers. But the database servers are not the
problem. The analysis servers are.
I then checked the event logs and they are empty as far as this issue is concerned. Actually, there are no errors on the SQL 2012 production box and the Data Warehouse box. I then checked the log that the installer creates during every step of the installation
and this is what is created when the dropdown is clicked for the analysis server configuration screen. The log file location is:
“C:\Users\admin\AppData\Local\Temp\2\SCSMSetupWizard01.txt”
In the file is the following text.

ACI Setup - How to Configure Data Warehouse Database - Partitoning
After reading the ACI Install Guide & Data Warehouse documentation, I have some questions regarding how to setup the database:
- Should database partitioning be setup? If so, what tables should be partitioned and what should they be partitioned by?
- Are there any other best practices or tips for setting up & tuning the database?
We are trying to avoid the (painful) situation of having to add partitioning later on; it is much easier to add it up front (if done correctly up front).
Thanks in advance for any advice!On the tables recommended for partitioning, the partition key is nullable. If ATG inserts a null value into the timestamp column of one of the partitioned tables, we'll receive an ORA-14300 or ORA-14440 error. Oracle isn't able to figure out what partition to map that record to.
Can the columns be changed to NOT NULL? Or, can the application guarantee a nullable value won't be inserted?
Here are some example columns:
ARF_SITE_VISIT.START_VISIT_TIMESTAMP --> TIMESTAMP(6) null
ARF_REGISTRATION.REGISTRATION_TIMESTAMP --> TIMESTAMP(6) null
ARF_LINE_ITEM.SUBMIT_TIMESTAMP --> TIMESTAMP(6) null
ARF_PROMOTION_USAGE.USAGE_TIMESTAMP --> TIMESTAMP(6) null
ARF_RETURN_ITEM.SUBMIT_TIMESTAMP --> TIMESTAMP(6) null
Thanks -
Error while creating data warehouse tables.
Hi,
I am getting an error while creating data warehouse tables.
I am using OBIA 7.9.5.
The contents of the generate_clt log are as below.
>>>>>>>>>>>>>>>>>>>>>>>>>>
Schema will be created from the following containers:
Oracle 11.5.10
Universal
Conflict(s) between containers:
Table Name : W_BOM_ITEM_FS
Column Name: INTEGRATION_ID.
The column properties that are different :[keyTypeCode]
Success!
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
There are two rows in the DAC repository schema for the column and the table.
The w_etl_table_col.KEY_TYPE_CD value for DW application is UNKNOWN and for the ORA_11i application it is NULL.
Could this be the cause of the issue? If yes, why could the values be different and how to resolve this?
If not, then what could be the problem?
Any responses will be appreciated.
Thanks and regards,
Manoj.Strange. The OBIA 7.9.5 Installation and Configuration Guide says the following:
4.3.4.3 Create ODBC Database Connections
Note: You must use the Oracle Merant ODBC driver to create the ODBC connections. The Oracle Merant ODBC driver is installed by the Oracle Business Intelligence Applications installer. Therefore, you will need to create the ODBC connections after you have run the Oracle Business Intelligence Applications installer and have installed the DAC Client.
Several other users are getting the same message creating DW tables. -

We have a four server set-up where SCSM, SCDW, and sqls for both are on different servers.

This should open the reporting website in IE. If this isn't working you should check the proxy settings in IE. If the URL doesn't work in IE it won't work in the SCSM console as well (and vice versa).

Actually I can't access to the reporting website. It asks me credentials 3 times and then return a blank page. Also error message comes to the EventViewer System log with id 4 and source Security-Kerberos.
The Kerberos client received a KRB_AP_ERR_MODIFIED error from the server "accountname".
The target name used was HTTP/"reporting services fqn". This indicates that the target server failed to decrypt the ticket provided by the client.
This can occur when the target server principal name (SPN) is registered on an account other than the account the target service is using.
Ensure that the target SPN is only registered on the account used by the server.
This error can also happen if the target service account password is different than what is configured on the Kerberos Key Distribution Center for that target service.
Ensure that the service on the server and the KDC are both configured to use the same password.
If the server name is not fully qualified, and the target domain (domain.com) is different from the client domain (domain.com), check if there are identically named server accounts in these two domains,
or use the fully-qualified name to identify the server.
I can access the website directly from the server which hosts Reporting Services.
Also I query "setspn -Q HTTP/"reporting services fqn" whit result NO SUCH SPN FOUND. -
I have a Data Warehouse Server that appears to be functioning but is running System Center Service Manager 2010 (w/ out SP1), Also have a functioning Configuration Management Server with Reporting Services Point installed the is running System Center
2012. Both systems are VM's running Windows Server 2008 R2 Enterprise w/ SP1 fully patched. Both systems are running SQL Server 2008 R2 as well. When I try to register the Data Warehouse Server via the GUI using the console or in Powershell it errors
out. Particularly on the GUI with the error "Unable to connect to data warehouse management server". I can browse to it, ping it, get the configuration management reports to run and show my AD assets, etc... but it will not register the DWS. I have
tried every suggestion TechNet has to offer and I am hitting a wall. Can someone please, please, please help!?!unplug modem and router and reboot.
check setting for network, verify password.

Syntax for WriterLoginName in Data Warehouse DB
Hello
I'm having a few issues with our management servers writing to the Data Warehouse DB. I've checked the 'Management Group' table and can see the WriterLoginName is set to
DOMAIN\sv-scom-dw - however, i'm just querying whether that field should read
sv-scom-dw
The account is in fact a domain account. It's listed as the 'Data Warehouse SQL Account' & 'Data Warehouse Action Account' (under Administration > Run As configuration > Accounts).
We have two entries in the database security (rights over OperationsMangerDW), one as DOMAIN\sv-scom-dw & a local SQL login called sv-scom-dw. Both accounts have the following permissions: apm_datareader, apm_datawriter, db_datareader, db_owner, OpsMgrReader,
OpsMgrWriter, public.
We're a SCOM 2012 R2 environment. All servers are 2012 R2, SQL is also 2012 standard.
Anyone faced a similar issue before? I'm seeing a lot of alerts in the Monitoring section for the Data Warehouse. One in particular:
Data Warehouse failed to discover performance standard data set. Failed to enumerate (discover) Data Warehouse objects and relationships among them. The operation will be retried.
Exception 'SqlException': Management Group with id ''5F201AB2-4B10-7FCC-C716-B2361102248D'' is not allowed to access Data Warehouse under login ''sv-scom-dw''
One or more workflows were affected by this.
Workflow name: Microsoft.SystemCenter.DataWarehouse.Discovery.StandardDataSet
Instance name: Performance data set
Instance ID: {B81C47FB-A80D-0FE5-A8DB-DC4544FC8DA6}
Management group: ******
As you can see from the alert the account referenced is 'sv-scom-dw' and not 'DOMAIN\sv-scom-dw'. Which is why I originally asked, should the field in the management table be updated?
Thanks, David.Hi guys.
Thanks for the responses, I shall provide an event ID shortly. In response to Mai, I've followed the link you've posted and I'm now checking the 'data source and related settings', so i've gone to http://localhost/reports on the Warehouse server (which
also hosts the reporting), and i've got the following error:
The report server cannot decrypt the symmetric key that is used to access sensitive or encrypted data in a report server database. You must either restore a backup key or delete all encrypted content. (rsReportServerDisabled)

Accessing Data Warehouse with HTML DB
I have a test data warehouse database 10g comprising of seven dimension tables and one fact table. When I access one table at a time, the query runs fine, but when I join two dimension tables or more to the fact table, the result set comes out wrong. The performance is also very poor. Is HTML DB not capable of properly accessing a data warehouse data?
Here is the query I'm having problem with:
SELECT p.prod_name, s.store_name, pr.week, sl.dollars
FROM sales sl, product p, period pr, store s
WHERE p.prodkey = sl.prodkey
AND pr.perkey = sl.perkey
AND p.prod_name LIKE 'Assam Gold%'
OR p.prod_name LIKE 'Earl%'
AND s.store_name LIKE 'Instant%'
AND pr.month = 'NOV'
AND pr.year = 2003
ORDER BY p.prod_name, sl.dollars DESC
Your input would be appreciated.I doubt this was intentional, but you are not joining the store table to anything. You do filter the rows from that table with the AND s.store_name LIKE 'Instant%' predicate, but it is not joined to any of the other 3 tables. Your query will essentially return the number of rows from the other 3 tables multiplied by the number of rows returned from store. SYou might think about grouping some of your predicates for readability and possibly for correct logic.SELECT p.prod_name, s.store_name, pr.week, sl.dollars
FROM sales sl, product p, period pr, store s
WHERE p.prodkey = sl.prodkey
AND pr.perkey = sl.perkey
-- Add missing predicate here
-- AND s.something = sl,p, or pr .something
-- end missing predicate
AND (p.prod_name LIKE 'Assam Gold%'
OR
p.prod_name LIKE 'Earl%')
AND s.store_name LIKE 'Instant%'
AND pr.month = 'NOV'
AND pr.year = 2003
ORDER BY p.prod_name, sl.dollars DESCHope this helps,

Only Alert Data is not being inserted in SCOM 2012 Data Warehouse database
Hi All,
Alert data is not getting inserted into SCOM Data Warehouse database since 10 days though I could see latest Performance data in DW DB. No changes were made as far I know on SCOM servers or DB's. I had this issue few months back
and got resolved by executing a qiery to create an entry for Data Warehouse Synchronisation server entry.
Now I have checked the discovered inventory and could see an entry present and it is healthy. Still, latest Alert data is not getting inserted into DW DB. Please help me out.

Regards, SureshHi,
Generally, data warehouse store a long-term data, and by default, it would keep 400 days data, I suggest check your configuration:
