Difference between Data Providers for Oracle

Hello,
There are 3 .NET Data Providers for access an Oracle Database:
1) ODP.NET, who uses Oracle API to access an Oracle Database.
2) Microsoft .NET Data Provider for Oracle, who comes in the Assemblie System.Data.OracleClient
3) Microsoft .NET Data Provider for OLE DB.
My questions are:
1) There is another Data Provider to access an Oracle DB ?
2) Which is better, for example to handle LOB fields ?
3) Which is better in performance ?
4) ODP.NET uses some Oracle API to handle a DB, and the others ?
5) What is the requirement (Oracle Client, OS) of each of them ?
Best Regards
Alfredo DS

I would recommend using ODP.NET. Overall, I've seen better performance from it than other Oracle providers. It requires the 9.2 client and any OS that the 9.2 client supports.
With respect to LOBs, the first ODP.NET version was consistently faster retrieving LOBs than other Oracle providers. The latest version of ODP.NET (and the upcoming version) have made some substantial improvements in LOB performance on top of that.

Difference between Data Provider and extractor.

Hi
Can someone help me in understanding difference between data providers and data extractor.
I have gone through some documents but not able to get the exact difference between them.
What is the exact role of data provider and extractor with respect to sap solution manager.
Is data provider== Data extractor?
Thanks,
Vijay

Hello Vijaya,
From my perspective the Data Providers are responsible for collecting metric values from the monitored objects on the managed sources systems and sending these to the Solution Manager Monitoring and Alerting Infrastrucure.
Data extractors on the other hand are the reporting objects which are defined on the BW part of Solution Manager and can be enabled by configuring some monitoring scenario's. Once these data extractors are enabled, they will use the data from the "Data Providers" (see above) to setup nice BW reportings on the Solution Manager monitoring dashboards.
I hope this answer helps you.

Difference between the XML for the "Initial System Data" in the module ERM

Hello,
I wan to know what's the difference between the XML for the "Initial System Data" in the module ERM of SAP GRC AC 5.3.
RE_init_clean_and_insert_data.xml
RE_init_append_data.xml
RE_init_methodology_data.xml
And what "Initial System Data" do I have to put?? the rule set?
I'm new in SAP GRC.
Thank you very much.
Pablo Mortera.

Pablo,
I am sorry but I am not able to get the question so I will explain as per my understanding. All of these three xml files contain necessary out of the box data which is required for ERM to function. Without this data, your ERM would not work so this is the first thing you want to do in ERM after successful installation.
After that, you will have to create connector and landscape and then synchronize transaction code, auth objects, fields, values etc by running through each background job one by one.

Difference between Data-centric and Document-centric use

Hi,
Can someone suggest what exactly is the difference between Data-centric and Document-centric use and examples if any.
Thanks in advance.
Chaitanya

Maybe it helps if you look at it this way...
Document centric: document centric use of xml data is data that you always use in its complete form. If you want to use the data, then you always will retrieve it as one entity or you save it as one entity. You are not interested in the xml data / information inside this "package" / document, you are only interested in its total form. Lets say, you have an invoice which can be printed on one sheet of paper. This paper that contains you data, will always be treated in a document driven way, that is, in its total representation: information containted on a sheet of paper (document).
Data centric. data centric use of xml, is usage of data were the main interest point is focused on only pieces of the total set of xml data within a document. So instead of being interested in the whole invoice, you only are interested in information like "amount of money to be payed" or "invoicenumber".
Handling of XML data comes with (hidden) costs. Knowing how your data will be used, has to be used, is one of the first steps in designing you environment (and will have an big impact if you choose poorly). For instance, if you know that your data will always be handled (and must be stored) in a document driven way, then it will make sense to store it based on CLOB based XMLType storage. This will garantee best performance retrieval for your xml document. If you now that your xml data has to be stored so that it can be handled in a data centric way, then Object Relational XMLType storage. If conditions are setup properly data retrieval, inserts and updates will be more cost efficient then when based on CLOB XMLType storage.
There are more differences and "cost markers" when or when not to use CLOB, OR or for instance Binary XML. The first two chapters of the XMLDB Developers Guide for Oracle 11g will give you a good head start making some of those decisions. Be also aware that you probably will have to make compromises. The current state of XML, for example, doesn't have the final solution yet for a uniform storage method.

Difference between "Data replication", "Data Cloning", "Data duplication" and "Data Migration"

Hi Gurus,
Can anyone tell me the difference between "Data replication", "Data Cloning", "Data duplication" and "Data Migration". I have gone through Google but doesn't find any appropriate answer for that where I can find the difference.
It would be highly appreciated if you give me a link for all and give me some point out.
Thanks & Regards
Nimai Karmakar

Here is how I see the terms used and understood by most folks
"Data replication"
This is the keeping the same data in sync in 2 different databases. Replication is the process of keeping data in sync between 2 environments/databases and not limited to Oracle to Oracle, it could be Oracle to MySQL to be kept in sync, MySQL to Oracle, Oracle to SQL Server, SQL Server to Oracle. The purpose of keeping data in sync can vary, but that is basic description of what it is.
"Data Cloning"
Make a copy of the data/database from one database environment to another, like for example taking production database and cloning the database to a pre-production database/environment for testing. Coning term is used more when copying a database not just data, but the whole database so typically you hear the reference "Database Cloning", but data cloning is basically the making a copy of the data from one place to another. Sometimes Cloning and Duplicating are used in the same way by folks as the basic end result is the same you are making a copy of the data to someplace else.
"Data duplication"
This is typically term when duplicating the data from one environment to another for a particular purpose, a lot of folks use "Data/Database Cloning" and "Data Duplication" in the same context, meaning they use them to mean the same thing, but I see more difference in the terms so when they are different Data Duplication is done when combining 2 databases to 1 therefore you can not clone the 2 databases into one so this term would be used more in those circumstances.
"Data Migration"
Moving data from one location/database to another location database, for example moving from MySQL to Oracle you would do a data migration from MySQL to Oracle as you are moving the data from MySQL to Oracle and going to leave it in Oracle. You could also be migrating to from Oracle 10g environment to a new Oracle 11g environment, therefore "Migration" is typically used when referring to moving the data from one environment to another and the source and target are different in location, database vendor, database version.
These are very simple ways of looking at the terms from my experience on how they are used.

What is the difference between data file & control file

what is the difference between data file & control file

Dear Deba s
Control file
Every Oracle Database has a control file, which is a small binary file that records the physical structure of the database. The control file includes:
The database name
Names and locations of associated datafiles and redo log files
The timestamp of the database creation
The current log sequence number
Checkpoint information
For more info look into these
[Control File Basic|http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14231/control.htm#i1006143]
Data File
You manage Data File in your Oracle database as part of Space Management. You can extend, create, drop, and alter tablespaces.
You especially need to avoid tablespace overflow, which is when a tablespace runs out of freespace in the allocated file or files. This happens when an object requires a new extent but there is either no freespace or insufficient freespace in the tablespace
For more info look into these links

What is Difference between ANSI SQL and ORACLE SQL

Hi,
I am going to take the assesment test for ANSI SQL Programming before that i want to know any difference between ANSI SQL and ORACLE SQL?
I am studying for SQL but the test will be ANSI SQL please let me give an idea about the both.
Thanks
Merina Roslin

Basically there is syntax difference between both of them.
Lets say i want to join two table EMP and DEPT based on DEPTNO.
With Oracle SQL format its like this.
select e.*
from emp e, dept d
where e.deptno = d.deptnoHere the joining condition goes in the WHERE clause.
With ANSI SQL format its like this.
select e.*
from emp e
join dept d
on e.deptno = d.deptnoHere the join condition is mentioned separately and not in WHERE clause.
Oracle supports ANSI SQL starting from 9i version.
You can read more about the syntax difference Here

Find difference between date

I need to know how i can find difference between date
like Joining date: 01-jan-2009 Today 10-jan-2010 result will be "1 year 10 days"
I need it in Oracle forms 6i. plz help me...

Hi,
In oracle forms you can use
RESULT :=
TRUNC ((:date2 - :date1 + 1) / 365)
|| ' year and '
|| MOD (:date2 - :date1 + 1, 365)
|| ' days';
in sql you can use
SELECT TRUNC ((:date2 - :date1 + 1) / 365)
|| ' year and '
|| MOD (:date2 - :date1 + 1, 365)
|| ' days'
FROM DUAL;

Counter KF with 1 & 0 and difference between data type NUMBER (DEC) and INTEGER (INT4)

Hi,
I need to create a counter kf which should populate 1 and 0 to this counter field. Please let me know is there any difference between data type
NUMBER (DEC) and INTEGER (INT4).
Please suggest.
Thanks & Regards,
Pavan kumar

Hi Pavan,
The basic difference between Number(DEC) and INT4 is its internal storage in system.
For Number (DEC) - Value internally stored as packed number with 3 decimal places whereas INT 4 as 4 byte integer without decimal places.
For counter KF, you can go for INT 4.
Hope this helps.
Thanks

Difference between data target & Infoprovider.

Hi all,
Difference between data target & Infoprovider.
why cube is best in performance wise other than ods,multiproviders.
Thanks,
cheta.

A data target is an object into which data is loaded. Data targets are the physical objects relevant during data modeling and when loading the data.
Structure
Data targets are:
InfoCubes
ODS objects
InfoObjects (characteristics with attributes, texts or hierarchies).
There are differences between:
Pure data targets for which no queries can be created or executed. An InfoCube might only be used as a data source for another InfoCube. This is also possible for ODS objects and InfoObjects.
If you want a characteristic to appear in the InfoProvider tree, you have to assign an InfoArea to it. You can define update rules for the characteristic in the InfoProvider tree, and use them to load attributes and texts.
You can turn a characteristic into a data target only if the characteristic contains texts or attributes. It is not possible to use update rules to load hierarchies.
Data targets for which queries can be defined. These are called InfoProviders.

Difference between Dates: BW Query???

Hello all,
A.I have to get the difference between dates i.e Date1 and Date2.
I have used a 2 formula variables for each one of them with Replacement path - Key - number as the settings.
When i execute the difference between the 2 formula variables, i get inconsistent results if the dates are from 2 different months.
Example(Correct Result)
Date1 = 14.02.2005
Date2 = 10.02.2005
Result = 4
Example(Incorrect Result)???????
Date1 = 14.02.2005
Date2 = 10.01.2005
Result = 104
Iam know that system is converting the date as a number like 20040214 and 22040110 and just substracts.....This is not correct....any solution to circmvent this problem???
B.If iam using a user-exit for variables, how to pass the values Date1 and Date2 to user-exit so that i can calculate the difference of days using a function module.
I know how to use a user-exit but not sure about working on 2 fields at a time for a formula variable????

1) For the first problem, I think you should play with the replacement path settings (type, offset,...). I did this before and I'm sure it worked.
2) If the variables are entered in the variable screen there is no problem to use a function module (it works with steps --> look at the how-to), but I think you want to calculate not on variables but on the keyfigure values itself, in this case you will have to use virtual characteristics. There is also a how-to about this, I can't help you with the details my self.

Difference Between data target and infoprovider

Hi Experts,
I am new to BW
What is the difference between data target and infoprovider
Thanks and Regards,
saveen

Hi Saveen,
InfoProvider is an object on which BEx queries are created. It provides information (data) to the queries when they are executed. InfoProviders may contain data (like cube) or may not contain data (like multiproivder and InfoSet).
Data Target is an object to which you will load the data, like cube, ODS or InfoObject. But it is not necessary that each data target is an InfoProvider...like you may have ODS objects that are not enabled for reporting, but you are loading data to them for staging purpose.
Hope this helps...

Whats basic difference between data and types while declearing the itab

hi,
like -> used for refering existing data elements in data dictionary or in sap
type -> used for refering existing data types in sap.
types: used for creating used defined structure of tables which has fields from more tahn one table.
diff b/w types and type in creation of internal tables is that when u create a table with types then u can use same for work area creation also.
ex:
TYPES : BEGIN OF t_vbap,
vbeln1 LIKE vbeln,
posnr LIKE posnr,
kwmeng LIKE kwmeng,
netpr LIKE netpr,
netwr LIKE netwr,
werks LIKE werks,
matnr LIKE matnr,
arktx LIKE arktx,
END OF t_vbap.
data: itab1 type t_vbap
        wa_itab1 type t_vbap.
when type is used then u have to create a defintion of work area for another time when internal table doesnt have headr line as
ex:
DATA : BEGIN OF t_vbap OCCURS 0,
vbeln1 LIKE vbap-vbeln,
posnr LIKE vbap-posnr,
kwmeng LIKE vbap-kwmeng,
netpr LIKE vbap-netpr,
netwr LIKE vbap-netwr,
werks LIKE vbap-werks,
matnr LIKE vbap-matnr,
arktx LIKE vbap-arktx,
END OF t_vbap.
DATA : BEGIN OF wa_vbap,
vbeln1 LIKE vbap-vbeln,
posnr LIKE vbap-posnr,
kwmeng LIKE vbap-kwmeng,
netpr LIKE vbap-netpr,
netwr LIKE vbap-netwr,

Difference Between Data Services Designer and Data Services Workbench

Hello All,
I am new to Data Services .
What is the difference between Data Services Designer and Data Services Workbench .
Am bit confused in the above two .
Please help me to understand the same.
Thanks in advance.
Aisurya

Workbench is used to create, display and modify the objects. It will display the source table data and we can see the logs of the job which we have executed and also we can see the status of a job. In bods 4.2 you can design the dataflow in workbench in previous release we don’t have that option but designer contains debugging option, you can write scripts, it will support all databases; these option are not available in workbench. for more information refer this document:
