Difference between data guard and active data guard
As in subject. Can we paid for both products?
>
Is this only one difference between this Data Guards?
>
The one (active DG) is an additional feature of the other (DG)
>
BTW, is that mean that Data Guard in each version (9-11) is free on EE?

Yes - but you need to license the Standby Database. So it is not really "free" - but you better ask that our sales people :-)

Difference Between Logical Screen and Active/Physical Screen
Hi All,
Could someone tell me what is the Diffrence Between Logical Screen and Active/Physical Screen and what is the reason for having two screens instead of one.
Thanks in Advance,
Joseph Reddy.Hi Marilyn,
Thanks You. I have found the answer to this.
All,
If you go to the SPRO>Logistics Execution>Mobile Data Entry-->Define Screen Management. Here you have two screens one is Logical Screen and another actual Screen and a program associated to this.
Here the Logical Screens are used within the program and Actual screens are the screens which are visible to the User. The Link between Logical and actual screen is present in the table T3130C. Program recognises logical screens.
Now suppose say certain functionality/create new transaction code for RF Device is not there in SAP and you want to Include/Create your own code in any of the User-Exits. Then you have to rename the actual screen to 9***. So that the system recognises the change in the screen and related User-Exit is executed.
Hope this is Clear.
Thanks & Regards,
Joseph Reddy. -

Without Data Guard Broker:
http://www.oracle.com/pls/db112/to_toc?pathname=server.112/e17022/toc.htm
With Data Guard Broker:
http://www.oracle.com/pls/db112/to_toc?pathname=server.112/e17023/toc.htm
See especially why you want to use the broker:
http://download.oracle.com/docs/cd/E11882_01/server.112/e17023/concepts.htm#i1013106
In short: You should have a good reason if you do not use the broker, because it is the officially recommended way to maintain Data Guard. It is even required for some features like Fast-Start Failover.

The difference between FIELD-SYMBOL and normal DATA TYPE
Dear experts,
Please see the example below, both are output the same result.
DATA: EXTERNAL_RECORD(4000),
POSITION TYPE I,
LENGTH TYPE N,
ENTRY TYPE STRING.
EXTERNAL_RECORD = '0005Smith0007Edwards0005Young'.
DO.
LENGTH = EXTERNAL_RECORD+POSITION(4).
IF LENGTH = 0.
EXIT.
ENDIF.
ADD 4 TO POSITION.
MOVE EXTERNAL_RECORD+POSITION(LENGTH) TO ENTRY.
WRITE ENTRY.
ADD LENGTH TO POSITION.
IF POSITION >= 4000.
EXIT.
ENDIF.
ENDDO.
--OR It can be written as--
DATA: EXTERNAL_RECORD(4000),
POSITION TYPE I,
LENGTH TYPE N.
FIELD-SYMBOLS <ENTRY>.
EXTERNAL_RECORD = '0005Smith0007Edwards0005Young'.
DO.
LENGTH = EXTERNAL_RECORD+POSITION(4).
IF LENGTH = 0.
EXIT.
ENDIF.
ADD 4 TO POSITION.
ASSIGN EXTERNAL_RECORD+POSITION(LENGTH) TO <ENTRY>.
WRITE <ENTRY>.
ADD LENGTH TO POSITION.
IF POSITION >= 4000.
EXIT.
ENDIF.
ENDDO.
Is there any special circumstances we need to use FIELD-SYMBOL?
Why is FIELD-SYMBOL is introduce in the first place?
Kindly advice with example.
Thanks in advance for those who can help me on this.HI,
You can use field symbols to make the program more dynamic. In this example the name of a table control is substituted by a field symbol. Thus you cal call the form with any internal table, using the name of the table control as a parameter.
Example
form insert_row
using p_tc_name.
field-symbols <tc> type cxtab_control. "Table control
assign (p_tc_name) to <tc>.
insert 100 lines in table control
<tc>-lines = 100.
Field symbols allow you to:
** Assign an alias to a data object(for example, a shortened
name for data objects structured through several hierarchies
- <fs>-f instead of rec1-rec2-rec3-f)
** Set the offset and length for a string variably at runtime
** Set a pointer to a data object that you determine at runtime (dynamic ASSIGN)
** Adopt or change the type of a field dynamically at runtime
** Access components of a structure
** (from Release 4.5A) Point to lines of an internal table
(process internal tables without a separate work area)
Field symbols in ABAP are similar to pointers in other programming
languages. However, pointers (as used in PASCAL or C) differ from ABAP
field symbols in their reference syntax.
The statement ASSIGN f to <fs> assigns the field f to field
symbol <fs>. The field symbol <fs> then "points" to the
contents of field f at runtime. This means that all changes to the
contents of f are visible in <fs> and vice versa. You declare
the field symbol <fs> using the statement FIELD-SYMBOLS: <fs>.
Reference syntax
Programming languages such as PASCAL and C use a dereferencing symbol
to indicate the difference between a reference and the object to which
it refers; so PASCAL would use p^ for a pointer instead of p, C would
use *p instead of p. ABAP does not have any such dereferencing symbol.
** In PASCAL or C, if you assign a pointer p1 to a pointer p2,
you force p1 to point to the object to which p2 refers (reference semantics).
** In ABAP, if you assign a field symbol <fs1> to a field
symbol <fs2>, <fs1> takes the value of the data object to
which <fs2> refers (value semantics).
** Field symbols in ABAP are always dereferenced, that is,
they always access the referenced data object. If you want to
change the reference yourself in ABAP, you can use the ASSIGN statement
to assign field symbol <fs1> to field symbol <fs2>.
Using field symbols
You declare field symbols using the FIELD-SYMBOLS statement.
They may be declared either with or without a specific type.
At runtime you assign a field to the field symbol using the ASSIGN
statement. All of the operations on the field symbol act on the field
assigned to it.
When you assign a field to an untyped field symbol, the field symbol
adopts the type of the field. If, on the other hand, you want to assign
a field to a typed field symbol, the type of the field and that of the
field symbol must be compatible.
A field symbol can point to any data object and from Release 4.5A,
they can also point to lines of internal tables.
The brackets (<>) are part of the syntax.
Use the expression <fs> IS ASSIGNED to find out whether the field
symbol <fs> is assigned to a field.
The statement UNASSIGN <fs> sets the field symbol <fs> so
that it points to nothing. The logical expression <fs>
IS ASSIGNED is then false. The corresponding negative expression
is IF NOT <fs> IS ASSIGNED.
An unassigned field symbol <fs> behaves as a constant with
type C(1) and initial value SPACE.
MOVE <fs>
TO dest Transfers the initial value SPACE to the variable dest
MOVE 'A' to <fs>
Not possible, since <fs> is a constant
(runtime error).
To lift a type restriction, use the CASTING addition in the
ASSIGN statement. The data object is then interpreted as though
it had the data type of the field symbol. You can also do this
with untyped field symbols using the CASTING TYPE <type> addition.
The danger with pointers is that they may point to invalid areas.
This danger is not so acute in ABAP, because the language does not
use address arithmetic (for example, in other languages, pointer p
might point to address 1024. After the statement p = p + 10, it would
point to the address 1034). However, the danger does still exist, and
memory protection violations lead to runtime errors.
A pointer in ABAP may not point beyond a segment boundary. ABAP does
not have one large address space, but rather a set of segments.
Each of the following has its own segment:
* All global data
* All local data
* Each table work area (TABLES)
* Each COMMON PART
You should only let field symbols move within an elementary field or
structure where ABAP allows you to assign both within the global data
and beyond a field boundary.

Differences between Oracle BAM and Oracle BI and Question BAM Data Objects
Hi,
I have two questions.
1. Can someone tell me differences between Oracle BAM and Oracle BI?
My understanding about Oracle BAM is, we use BAM to build Dashboards or Reports.
We can also build DashBoards or reports using Oracle BI.
I am not able to understand why Oracle has two tools for same purpose?
Which tool is more powerful and user friendly(Oracle BI or Oracle BAM)?
2. Every time we plan to develop Dashboard or report in BAM, we need to create BAM ADC Data Object to store Data (i.e first step is to get data from external database or application and second step is to store data in BAM ADC data object).
My understanding is we have an extra step(i.e creating Data Object) in Oracle BAM to develop a report or DashBoard
I am wrong pl correct me?

What is difference between data base structure and stucure in program
what is difference between data base structure and stucure declared in program level . can explain cleary if knows
Hi,
Data base structure is global decalaration you can reffer this structure in any of your developments, when ever you cahange this structure the changes automatically will get updated in all the programs.
coming to structures in program it is local to your program only, if you want to change the structure again you have to open the program and do the necessary changes.
Reward if useful.
Thanks,

Difference between Data staging and Dimension Table ?
Difference between Data staging and Dimension Table ?
Data Staging:
Data extraction and transformation is done here.
Meaning that, if we have source data in flat file, we extract it and load into staging tables, we take care of nulls, we change datetime format etc.. and after such cleansing/transformation at then end, load it to Dim/Fact tables
Pros: Makes process simpler and easy and also we can keep track of data as we have data in staging
Cons: Staging tables need space hence need memory space
Dimension Table:
tables which describes/stores the attribute about specific objects
Below is star schema which has dimension storing information related to Product, Customer etc..

Difference between date info object in characteristics and keyfigure
What is the difference between "date" data type in characteristic and keyfigure?
Thanks in advance.
RajHi Rajasekhar,
If date is characteristics,query can be analysed based on date and filters can also be set using this date.
If it is key figure query cannot be analysed based on date,
Based on requirements,we have to decide whether it should be chatracteristic or key figure

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 kumarHi 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.

Difference between relational integrity and data intigrity
hi
could anybody tell me
what is the difference between
relational integrity and data intigrity
tahnx
kals.hi,
Data Integrity
Data integrity means, in part, that you can correctly and consistently navigate and manipulate the tables in the database. There are two basic rules to ensure data integrity; entity integrity and referential integrity.
The entity integrity rule states that the value of the primary key can never be a null value (a null value is one that has no value and is not the same as a blank). Because a primary key is used to identify a unique row in a relational table, its value must always be specified and should never be unknown. The integrity rule requires that insert, update, and delete operations maintain the uniqueness and existence of all primary keys.
The referential integrity rule states that if a relational table has a foreign key, then every value of the foreign key must either be null or match the values in the relational table in which that foreign key is a primary key.
What is a Relational Integrity?
A relational database contains tables of data which are related to each other. For example, articles are related to the author who wrote them, and conversely, authors are related to the articles they wrote. (Sounds obvious, and it is.) That's the relational part.
When we work with a relational database, we naturally expect that data in related tables stay related. For example, articles written by MartinB should always be related to MartinB and never be confused with articles written by any other author. That's the integrity part.
Relational Integrity is also called Referential Integrity, perhaps because the mechanism for ensuring integrity is implemented by the way the tables reference each other. Both terms are okay with me. I usually just say RI anyway.

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,
VijayHello 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 data target and infoprovider
Hi Experts,
I am new to BW
What is the difference between data target and infoprovider
Thanks and Regards,
saveenHi 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... -

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:
