The use of setBandwidthLimit
As title. What will come out if the actual required bandwidth
did exceed the setBandwidth limit? Drop frame or what?
Please advise and thx.
Hi,
Just went over this on Stefan Richters Flashmedia list:
Using setbandwidthLimit in sever side actionscript will force
the data to be under the max rate you specified. And yes, it will
first attempt to drop frames of video if you hit the max rate.

We have purchased 5 apple minis and would like them all on one account, that way we can monitor the use of these units. They will be used strickly for a business application. Can I use one account in itunes or must i have multiple.
Not going to happen the way you want it to.
When you add a gift card balance to the Apple ID, it's available for the Apple ID.
Probably best to create unique Apple ID's for each... this will also make things easier in the future as purchases are eternally tied to the Apple ID they were purchased with. -
Wield char with the use of matnr
Hi All,
my requirement is like:
I need 1 selection option which seems like parameter type mara-matnr.
when I put any material with the using of "*", it sud be fetch all the material with combination.
I did the code for that but somtime it fails..
TABLES: rqm00.
TYPES : BEGIN OF tp_matnr,
matnr TYPE mara-matnr,
END OF tp_matnr.
DATA: w_text TYPE string.
CONSTANTS: c_wild TYPE c VALUE '*',
c_per TYPE c VALUE '%'.
DATA: t_matnr TYPE STANDARD TABLE OF tp_matnr,
wa_matnr type tp_matnr.
SELECT-OPTIONS : s_matnr FOR mara-matnr NO INTERVALS NO-EXTENSION.
IF s_matnr-LOW CA c_wild.
W_TEXT = S_MATNR-LOW.
REPLACE ALL OCCURRENCES OF c_wild IN s_matnr-LOW WITH c_per.
ENDIF.
SELECT matnr
FROM mara
INTO TABLE t_matnr
WHERE matnr LIKE S_MATNR-LOW.
IF SY-SUBRC = 0.
loop at t_matnr into wa_matnr.
write: wa_matnr-matnr.
endloop.
ENDIF.
What should I do? what is the right solution which should not be fail in any condition.
Thanks & Regards,

On the use of VARCHAR2 vs. CHAR
I'm posting an e-mail thread that has been moving around in my organization, whith guidance from an Oracle representative.
The basic issue concerns the use of CHAR vs. VARCHAR2 when defining a table in Oracle.
I would like to get some comments from the community at large.
1. Business semantics should be represented in every aspect of a database, application, and design as far as I am concerned. Noteably, if the business rule at a corporate entity is clearly stated that when using Oracle the use of CHAR should be limited to those attribute implementations which have the following characteristics; a) The attribute may not be null, b) The attribute must have a character in each of the declared positions.
2. When the Visual Basic application began writing data to the CHAR columns in your application someone should have had a discussion with the developer to find out why this was happening. If the business semantics changed then the logical implemention of the business semantics should have changed as well. That the two were disconnected is not a problem with the CHAR type, it is a problem with the designer or the developer. The bottom line on this instance is that the column should have been defined as a VARCHAR2 data type since the business semantics no longer complied with the criteria set forth in the previous paragraph.
3. I think Oracle trys to load as much of the data from a table or index into shared memory, in this case the database block buffers, as it can in order to facilitate query operations. If Oracle has enough memory and can load a table or index into memory, it will do so. At the same time the database engine will move previously cached data out of memory to accommodate the new requirement.

Thank you for the detail information on CHAR and VARCHAR2. It got me thinking with a DBA hat. I worked as a DBA before and I did use the CHAR type and I will share my experience/thought on CHAR.
I don't like to use the char type like Tom has advised because Oracle does not check to see if the value being inserted fills up the column or not which can lead to a problem. And there is no performance gain or save space in Oracle.
I worked as a DBA before, I used char type on the "must fill/always filled" column (pre DMDC). The application was written in VB with Oracle back end. At some point, VB started inserting values that are short of the column width and created a minor problem (it was supposed to be filled column). The problem was quickly identified and fixed, but it caused an issue.
I realize that I don’t want to define it as a "must fill/always filled" column if you can't enforce it by simply defining the char data type on a table and prevent possible issue in the future.
For a manager, in order to use the char properly, you have to hire client developers with Oracle experience or provide a basic Oracle training in order to avoid the problem I mentioned above in order to use the char type correctly.
I think you, Tom and I are saying the same thing really. Only difference is that Tom and I can not think of a good reason why anyone would like to indicate the business semantics using column type on the database, when it can lead to more work/issues.
In regards to wasted 25 million byes, why would Oracle load the table with 25 million rows? Shouldn't it use an index? Don't you have a serious problem if Oracle is loading table with the 25 million rows?
Just my two cents... : )
-----Original Message-----
May I beg to differ?
CHAR plays a vital role in the intuitive interpretation of a database schema. If designed correctly, the use of CHAR tells anyone who is in the know that this is a must fill column. Thus if a column is defined as CHAR(3) everyone should know that the column will always contain three characters. Defining the column as VARCHAR2(3) does not tell you anything about the data other than that the column may contain 0-3 characters.
Also, If a column is defined as CHAR the column should always be populated. One of the nice features of VARCHAR2 is that if the column is defined at the end of a table, there is no storage overhead until that column is actually populated. Thus if you have a table that has an identifier that is nine characters in length and will always be populated with nine characters, an attribute which describes the type of identifier which is contained in the first column and which must always be populated and is a must fill attribute, and another column which is descriptive and may vary in length or not be populated at time of insert; the following definition does not express the business semantics of the entity:
COL_CD VARCHAR2(9)
COL_TYP_TXT VARCHAR2(26)
COL_TYP_CD VARCHAR2(2)
The above definition also does not take advantage of inherent storage features of Oracle; notably there is a wasted place holder between COL_CD and COL_TYP_TXT and between COL_TYP_TXT and COL_TYP_CD. The next definition does take advantage of the storage features but does not represent the business semantics of the entity:
COL_CD VARCHAR2(9)
COL_TYP_CD VARCHAR2(2)
COL_TYP_TXT VARCHAR2(26)
The above definition does not waste space storing a place holder between COL_TYP_CD and COL_TYP_TXT if the COL_TYP_TXT may be null. The column separator will only be used when the column contains data. The below definition satisfies both the storage and business semantics issues:
COL_CD CHAR(9)
COL_TYP_CD CHAR(2)
COL_TYP_TXT VARCHAR2(26)
This may seem pedantic in nature until you consider the situation where there are 25 million rows in the table represented by the above entity. If each row has a NULL COL_TYP_TXT value then the first example wasted 25 million bytes of storage and 25 million bytes of memory if the full table is loaded into memory. This is an issue which cannot be ignored in high volume databases.
You may wish to know why it is important to define a must fill/always fill column as a CHAR to express the business semantics of an attribute. I can't give a definitive answer to that other than to say that it is just good database manners.
So please, continue to use CHAR when the shoe fits. Don't throw something away that has use just because it is not popular or in the mode.
Also, if I am mistaken in any of the above, please feel free to educate me.
Thanks.

Subject: RE: Oracle on the use of VARCHAR2 vs. CHAR
Ignore if you already got this. This is just FYI.
-----Original Message-----
Below is a detailed answer to your VARCHAR2 or CHAR questions from our Database expert Tom Kyte. The short answer is VARCHAR2 is what you want to use. If you have any questions or want to discuss this in more detail let me know.
A CHAR datatype and VARCHAR2 datatype are stored identically (eg: the word 'WORD' stored in a CHAR(4) and a varchar2(4) consume exactly the same amount of space on disk, both have leading byte counts).
The difference between a CHAR and a VARCHAR is that a CHAR(n) will ALWAYS be N bytes long, it will be blank padded upon insert to ensure this. A varchar2(n) on the other hand will be 1 to N bytes long, it will NOT be blank padded.
Using a CHAR on a varying width field can be a pain due to the search semantics of CHAR.
Consider the following examples:
ops$tkyte@8i> create table t ( x char(10) ); Table created.
ops$tkyte@8i> insert into t values ( 'Hello' );
1 row created.
ops$tkyte@8i> select * from t where x = 'Hello';
X
Hello
ops$tkyte@8i> variable y varchar2(25)
ops$tkyte@8i> exec :y := 'Hello'
PL/SQL procedure successfully completed.
ops$tkyte@8i> select * from t where x = :y; no rows selected
ops$tkyte@8i> select * from t where x = rpad(:y,10);
X
Hello
Notice how when doing the search with a varchar2 variable (almost every tool in the world uses this type), we have to rpad() it to get a hit.
If the field is in fact ALWAYS 10 bytes long, using a CHAR will not hurt -- HOWEVER, it will not help either.
The only time I personally use a CHAR type is for CHAR(1). And that is only because its faster to type char(1) then varchar2(1) -- it offers no advantages.
If you just use varchar2 everywhere, no problem
My advice is, has been, will be very loudly stated as:
IGNORE THE EXISTENCE OF CHAR.
period. If you never use char, you never compare char to varchar2, problem solved.
And if you use char and compare a char(n) to a char(m) they will never compare either.
Just say NO TO CHAR.

Restrict the use of index while quering
Hi All
I have a simple emp table with columns empid, name, sal. Empid has a primary key imposed.
Now when i write a statement like this,
select * from emp where empid = <value>;
the optimizer will make use of index.
The question is........... is there anyway to make oracle bypass the use of index without change in above query.Why do you worry of performance issues when the table size is small , when it is huge and the column you r trying use in the query is also indexed the oracle finds the Best execution method to do the execution whether index exists or not , Oracle has a very intelligent Optimizer and no need to use hints unless and until it is really mandatory or when u r using a very complex query where Oracle is not able to deduce the best Execution plan . But by all means you should look at the execution plan how a cerain query Oracle knows of doing it or when u have a diferering opinion then only at that point you force a Optomizer Hint . For other normal cases like the one you are asking it is best to get the results how Oracle executes it and no forcing is required .

Hi all,
What is the use of this form in include RV61B901?
How does this code send any information to the program calling it? Is Sy-subrc global so that main program will know the reuslts?
Code:
FORM KOBED_901.
DATA : l_anzpk LIKE likp-anzpk.
SELECT SINGLE anzpk FROM likp
INTO l_anzpk
WHERE vbeln = komkbv2-vbeln.
IF l_anzpk NE 0.
sy-subrc = 4.
exit.
ENDIF.
sy-subrc = 0.
ENDFORM.
Thanks,
Charles.Hello,
This form sets the value of sy-subrc(which is global) based
on the value of l_anzpk.

What is the use of additon in up to 1 rows in SELECT statement
Hi All,
What is the use of up to 1 rows in select statement.
for example
SELECT kostl
FROM pa0001
INTO y_lv_kostl UP TO 1 ROWS
WHERE pernr EQ pernr
AND endda GE sy-datum.
ENDSELECT.
I'm unable to get in wat situations we hav to add up to 1 rows
please help me out...
Thanks,
santosh.Hi,
Use "select up to 1 rows" only if you are sure that all the records returned will have the same value for the field(s) you are interested in. If not, you will be reading only the first record which matches the criteria, but may be the second or the third record has the value you are looking for.
The System test result showed that the variant Single * takes less time than Up to 1 rows as there is an additional level for COUNT STOP KEY for SELECT ENDSELECT UP TO 1 ROWS.
The 'SELECT .... UP TO 1 ROWS' statement is subtly different. The database selects all of the relevant records that are defined by the WHERE clause, applies any aggregate, ordering or grouping functions to them and then returns the first record of the result set.

What is the use of Alternative Calculation Type =2 and 4
Dear Friends
In pricing procedure in gross value, Net value for Item and Net value has Alternative calucation type is 2.
What is the use of it?
Without using it these value line are also fetching net value then what is the work of it. Please give me detail information with its effects in pricing condition tab page in sales document.
Thanking You
ArunArun biswal,
Correct Biswal. We have at varoius stages within Pricing procedure the "net value" which is calculated. Not only the alternative calculation type "2" is used if you notice carefully they are stored as subtotals at various levels.
For Ex Gross Value --> Subtotal =1 --> Calc type = 2
similarly for Net value for Item --> Subtotal =2 --> Calc type = 2
Net value 2 --> Subtotal =3 --> Calc type = 2
See, these are used to calculate the net value at various levels in pricing. The calculation Type has got a set of routines that will facilitate us in pricing. SAP has provided certain clauclated formulas or routines to facilitate us during calculation within pricing . Here the "2" is used for calculation without tax and store it as subtotal and display it or use it for further calculations.
We can use this "netvalue" amount for further calculations. It is used for clarity purpose when you issue a statement to customer. (like Confirmation order) at various levels like discount amt involved, Freight involved, Rebate amount invloved.....
Even without this Calc type or using sub total u can proceed....
Finally we have TOTAL --> Subtotal =A --> Calc type = 4
In the above line we have Calc type as 4, which means when you use TAX this calc type is used .
Routines are used to facilitate your process....

Can you help me understand the use of the word POSITION in TR and CFM?
Hi,
I am trying to have a view of typical BI reports in TR and TM/CFM so through my research I came to the following link:.
http://help.sap.com/saphelp_nw2004s/helpdata/en/62/08193c38f98e1ce10000000a11405a/frameset.htm
My problem on this link and other postings on this site seem to be the same. Can you help me understand the use of the word POSITIONS in these context:
1. Our client has asked for financial transaction reports in BW, such as position of Borrowings, Investments and Hedge Operations (TM data).
2. I have a requirement on, some reports related to Money Market (Fixed Term Deposits, Deposits at Notice) something on FSCM-Treasury and Risk Manager. These reports will be similar to that of Loans, i.e. Position statement, flow statement, etc.
3. The set of position values for a single position or a limited amount of positions can be reported by transactions TPM12 and TPM13 in R3.
4. 0CFM_C10 (Financial Positions Cube)
Do you have some simple report outputs to help clarify how the word POSITION is used in such environments?
Thanks

I have a problem with Safari in IOS 8 on my iPad 3. The bookmarks take up a third of the screen and I can't seem to make the bookmarks disappear until I need them. The useful part of the screen is therefore very small. Any suggestions gratefully appreciated.
OK, it now sort of works. A couple of problems here:
After updating IOS, Safari iCloud was "automatically" switched off
Switching it on had no effect
resetting my iPad automatically switched off safari iCloud again
after switching it back on, it said "turning off safari data"
switched it off and on again, now it said : "turning on safari data" and the sync worked
On IOS 7 no problems
The bookmarks not being displayed was because after pressing the book icon, it defaulted to showing the history and I had to press "Back" to get to the other options -

What is the use of creating a detail object on a measure.
Hi Experts,
In BI 4.X business layer, we can create a detail object of a dimension and as well as measure.
Can you please let me know what could be the use of the detail object of a measure object?
In the business layer, it is showing like this...
<Measure object>
-><Detail Object>
Dimensions have attributes, we create those attributes as details objects.
when we want to see the different grains of the measure in one report. we will use these details objects.
Example:
1. Query 1 returns country, sales revenue
2. Query 2 Returns Country,State,Sales revenue.
But in the report if we want to show the State wise Revenue. It is not possible bcz both the quires are returning different grain.
state object is incompatible object, so you can't drag the object into report.
in this scenario we will merge the Country dimension , create the state object as details with merged dimension, then you can drag the state details detail object.
this will give expected results Country and State wise revenue.
Normally Dimensions and details objects will drives the measures values in report.
So, Detail object on measure not helpful in case of relational database(Please correct me if i am wrong). It is useful only for OLAP database because when I have created a webi report on top of BEx query then it is automatically created a detail object on measure object.
As far I know, 'Measure attribute' introduced for OLAP based business layer. which can provides information for the formatted value like unit, currency or value.
For example:-
Amount is key figure in BEx query and when I have created Webi report on top of that then it will create three object.
1. Amount as meausre.
->2. Amount currency(detail).
->3. Amount formatted value(detail).
Below is the output after running the report.
Amount || Amount currency || Amount formatted value
30 || $ || 30.00
8 || $ || 8.00
I have found one difference, We can't implement the index awareness on detail object which we have created on measure object although we can implement the index awareness on detail object which we have created on top dimension object.
But Still I am looking for good example of Detail object on measure object..
Any thought would be welcome...
Thanks,
SachinI moved this to the Semantic Layer space for faster response.

I have verified managing ports in oracle documentation, it was mentioned that if one port is busy it will try to connect to another port in the range of ports mentioned during the installtion. DBAs verified ports related file and it was blank. and they are not agreeing with this reason. Please HELP me in finding the correct REASON for this.
