What's the difference between MSJVM and SUN JVM
Sometimes I can run a program under MSJVM more stable (faster) than that under SUN JVM. Would you please tell me why or tell some difference between them?? Many thanks.

You either used the MS VM linkage format, which resembles (strongly) how C# does it or you were not using the MS VM but rather the Sun one.
The fact that MS Java supported third party dlls does not make it JNI. JNI was a specific specification on exactly how such support would be provided. And MS Java did not have it.

The following from Microsoft itself asserting that JNI cannot be required part of java. Search for "JNI". Presumably if MS was claiming that it wasn't required then obviously they knew that it wasn't in fact in there.

What's the difference between "overloading" and "overriding" in Java
What's the difference between "overloading" and "overriding" in Java
hashdata wrote:
What is the real-time usage of these concepts...?Overriding is used when two classes react differently to the same method call. A good example is toString(). For Object it just returns the class name and the identityHashCode, for String it returns the String itself and for a List it (usually) returns a String representation of the content of the list.
Overloading is used when similar functionality is provided for different arguments. A good example is [Arrays.sort()|http://java.sun.com/javase/6/docs/api/java/util/Arrays.html#sort(byte%5B%5D)]: all the sort() methods do the same thing (they sort arrays), but one sorts byte-arrays, another one sorts int-arrays, yet another one sorts Object-arrays.
By the way, you almost certainly mean "real-world" usage. "real-time" (and thus "real-time usage) means something entirely unrelated to your question. -
What are the differences between jdk and sdk
what are the differences between jdk and sdk?? thanks
Just marketing whims.
SDK = software development kit
JDK = Java development kti
Sun has use both names to refer to its SDK for Java. I forget which one they're using now, but they've switched a couple of times. -
What is the difference between IPortalComponentContext and ServletContext ?
1) What is the difference between IPortalComponentContext and ServletContext or PageContext?
2) Both IPortalComponentContext and ServletContext are Same . If Both are Same Both Can be interchangeably Used?
3) If Both IPortalComponentContext and ServletContext are not same ,what is the specific functionality of each. I mean when is the IPortalComponentContext used and when is ServletContext is used?
4) can any please explain the difference and functionlity of each code snippet?
Thanks and Regards
Prasad.YHi Prasad,
what both contexts have in common is, that the context gives access to some resources the container provides.
Nothing else.
The servlet context is rather an application context of any java webapp and exists once per vm, a PortalComponentContext exists for every component and represents a view of the context in which the runtime runs the component.
To answer your questions shortly:
1) http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/ServletContext.html
https://media.sdn.sap.com/javadocs/preNW04/SP2/60_sp2_javadocs/runtime/com/sapportals/portal/prt/component/IPortalComponentContext.html
2) NO!

What is the difference between #variable_name and :variable_name?
Hi!
What is the difference between #variable_name and :variable_name?
I have found that if we use alphanumeric variable then :variable_name return value in quotes but #variable_name without quotes.
Why it does not work in the same way for variable default values when variable is used in filter? (It works in mapping)
I use variable in filter like T.OUT_DATE>convert(datetime,:LAST_UPDATE_DATE,121)
When I use my variable in package and do refresh it works fine. But when I try to execute the same interface with variable default value I get error. Seems that variable name has been not changed to the value. It does not work with default value in quotes neither without quotes.
Any ideas how to solve that?
Thank you in advance!
Edited by: user13278245 on Sep 15, 2010 4:34 AMQuestion is how to make it work with default value, when I execute interface standalone, not in package? And why it works in mapping but not in filter?
+ I have found that it works if source is Oracle. It doesn't work only for MS SQL source.

What is the difference between start() and run()
Hi:
what is the difference between start() and the run()???
in my app, i have
Console.debug( "starting thread to listen for clients" );
_server = new Server( this );
_server.start();
_server extends Thread..
why everytime i use server.start(); my app will terminate on it is own, even though in my servr.run() method, i have a while loop
and if i call _server.run() explicitly in my code, that while loop will be in execution
can someone let me know??
thnxwhat is the difference between start() and the
run()???start() is a method on Thread that tells it to start.
run() is a method in the object that the thread executes.
why everytime i use _server.start(); my app will
terminate on it is own, Err.... I'm not convinced this is true. It'll throw an IllegalThreadStateException, if you try to restart an existing thread.
If that's what you're saying.
even though in my _servr.run()
method, i have a while loopI don't see the connection. Are you saying that the while loop never terminates, and you don't see why the thread is terminating?
and if i call _server.run() explicitly in my code,
that while loop will be in executionIf you call server.run() explicitly, then run() will be executed in the same thread that you called it in. -
What is the difference between exists and in
hi all
if i have these queries
1- select ename from emp where ename in ( select ename from emp where empno=10)
and
2- select ename from emp where exists ( select ename from emp where empno=10)
what is the difference between exists and in is that only when i use in i have to bring the field name or what.... i mean in a complex SQL queries is it will give the same answer
ThanksYou get two entirely different result sets that may be the same. Haah! What do I mean by that.
SQL> select table_name from user_tables;
TABLE_NAME
BAR
FOO
2 rows selected.
SQL> select table_name from user_tables where table_name in (select table_name from user_tables where table_name = 'FOO');
TABLE_NAME
FOO
1 row selected.
SQL> select table_name from user_tables where exists(select table_name from user_tables where table_name = 'FOO');
TABLE_NAME
BAR
FOO
2 rows selected.So, why is this? the WHERE EXISTS means 'if the next is true', much like where 1=1 being always true and 1=2 being always false. In this case, where exists could be TRUE or FALSE, depending on the subquery.
WHERE EXISTS can be useful for something like testing if we have data, without actually having to return columns.
So, if you want to see if an employee exists you might say
SELECT 1 FROM DUAL WHERE EXISTS( select * from emp where empid = 10);
If there is a row in emp for empid=10, then you get back 1 from dual;
This is what I call an 'optimistic' lookup because the WHERE EXISTS ends as soon as there is a hit. It does not care how many - only that at least one exists. It is optimistic because it will continue processing the table lookup until either it hits or reaches the end of the table - for a non-indexed query. -

What is the difference between TO_CHAR and TO_DATE()?
Hi everybody,
i am facing a problem in my system.It is quite urgent, can you explain me "What is the difference between TO_CHAR and TO_DATE()?".
According to user's requirement, they need to generate a code with format "YYMRRR".
YY = year of current year
M = month of current month (IF M >=10 'A' ,M >=11 'B' , M >=10 'C')
RRR = sequence number
Example: we have table USER(USER_ID , USER_NAME , USER_CODE)
EX: SYSDATE = "05-29-2012" MM-DD-YYYY
IF 10
ROW USER_ID , USER_NAME , USER_CODE
1- UID01 , AAAAA , 125001
2- UID02 , AAAAA , 125002
10- UID010 , AAAAA , 12A010
This is the original Script code. But This script runs very well at my Local. Right format. But it just happens wrong format on production.
12A010 (Right) => 11C010 (Wrong).
SELECT TO_CHAR(SYSDATE, 'YY') || DECODE( TO_CHAR(SYSDATE, 'MM'),'01','1', '02','2', '03','3', '04','4', '05','5', '06','6', '07','7', '08','8','09','9', '10','A', '11','B', '12','C') || NVL(SUBSTR(MAX(USER_CODE), 4, 3), '000') USER_CODE FROM TVC_VSL_SCH
WHERE TO_CHAR(SYSDATE,'YY') = SUBSTR(USER_CODE,0,2)
AND TO_CHAR(SYSDATE,'MM') = DECODE(SUBSTR(USER_CODE,3,1),'1','01',
'2','02', '3','03', '4','04', '5','05',
'6','06', '7','07', '8','08', '9','09',
'A','10', 'B','11', 'C','12')
I want to know "What is the difference between TO_CHAR and TO_DATE()?".try to use following select
with t as
(select TO_CHAR(SYSDATE, 'YY') ||
DECODE(TO_CHAR(SYSDATE, 'MM'),
'01', '1',
'02', '2',
'03', '3',
'04', '4',
'05', '5',
'06', '6',
'07', '7',
'08', '8',
'09', '9',
'10', 'A',
'11', 'B',
'12', 'C') as code
from dual)
SELECT t.code || NVL(SUBSTR(MAX(USER_CODE), 4, 3), '000') USER_CODE
FROM TVC_VSL_SCH
WHERE SUBSTR(USER_CODE, 1, 3) = t.codeand yes you need check time on your prodaction server
good luck

What is the difference between upgradation and migration.
Hi Guru's
what is the difference between upgradation and migration.
actuallly i involved in upgradation project, here my role is
1. first i check the query's in 3.5 save the query and transport the query. and check the query in bex analyzer also.
2. go to BI .7 find the query;s ,give the query name and save the query ,
3. once save the query, again will come to 3.5 open the query , it will not open. this is my job here,
come to 7.0 check the query in analyzer also.
i am having littile bit confusion, how it will comes query in 7.0, why are u saving the query's in 3.5 and 7.0
query's already available in 7.0 why are u doing this work?
can i know the upgrades those objects, is it neccessary, if necessary how can i upgrade.
infoobje , transferrules, transferstructure ,infosoure, datasoure,updaterules, ods, cubes.
Points will be Assingned ,
Thanks & Regards
prabhavathiHi,
I was talking in a general sense not on a query level.
If your taling about migration in that level meaning as a part of larger upgradation (in your case 3.x to 7) there may be many places where you need to do this kind of activities.
Fr eg migration into new data flow, Migration of Web templates from BW 3.x to Netweaver 2004s, etc
Hope this helps.
Thanks,
