Pls tel me what is the diffrence between snapshot isolation level of mssql and oracels isolation level

Hi,
In mssql i am using following things.
I have two database D1 and D2, i am using snapshot isolation (ALTER DATABASE MyDatabase
SET ALLOW_SNAPSHOT_ISOLATION ON) in both database.
Following is the situation.
1) There is one SP sp1 ( it can be in any database d1 or d2), it updates d2 from d1.
2) d2 is used for reading by web, execept above SP sp1
3) d1 gets updation from web in readcommite isolation.
4) both database will be on same instence of mssql.
Q1) wanted to know how to implement the same thing in oracle 11x express edition.
Q2) is there any diffrence between snapshot isolation level of mssql and oracel.
any link would be help full.
yours sincerely

>Q1) should i set the option to OFF after the process(ts) is complete
No keep it on.
>Q2) ALLOW_SNAPSHOT_ISOLATION ON , will affect other isolation level's transactions
No it will not affect any other transaction isolation level.
>Q3) is my choice of isolation level for process(ts) is correct or there can be any other solution.
Seems fine, although there are probably many other solutions.

Hi,
BAPI's are associated with Business Objects and also they are RFC enabled.
But RFC's are the FM's which can be called from external systems, those FM's can be used in many places based on the applications..

What is the diffrence between sap events and application events

Hi all,
what is the diffrence between sap events and application events.Can any one tell me with examples.
regards,

Hi,
Look at this,
<b>System Events (Default)</b>
The event is passed to the application server, but does not trigger the PAI. If you have registered an event handler method in your ABAP program for the event (using the SET HANDLER statement), this method is executed on the application server.
Within the event handler method, you can use the static method SET_NEW_OK_CODE of the global class CL_GUI_CFW to set a function code and trigger the PAI event yourself. After the PAI has been processed, the PBO event of the next screen is triggered.
The advantage of using this technique is that the event handler method is executed automatically and there are no conflicts with the automatic input checks associated with the screen. The disadvantage is that the contents of the screen fields are not transported to the program, which means that obsolete values could appear on the next screen. You can work around this by using the SET_NEW_OK_CODE method to trigger field transport and the PAI event after the event handler has finished.
<b>Application Events</b>
The event is passed to the application server, and triggers the PAI. The function code that you pass contains an internal identifier. You do not have to evaluate this in your ABAP program. Instead, if you want to handle the event, you must include a method call in a PAI dialog module for the static method DISPATCH of the global class CL_GUI_CFW. If you have defined an event handler method in your ABAP program for the event (using the SET HANDLER statement), the DISPATCH method calls it. After the event handler has been processed, control returns to the PAI event after the DISPATCH statement and PAI processing continues.
The advantage of this is that you can specify yourself the point at which the event is handled, and the contents of the screen fields are transported to the application server beforehand. The disadvantage is that this kind of event handling can lead to conflicts with the automatic input checks on the screen, causing events to be lost.
Hope u understood.
Thanks&Regards,

What is the diffrence between extends and creating new object?

HI ALL,
what is the diffrence between extends and creating new object?
meaning
class base{
class derived extends base{
class base{
class derived {
derived(){
base var = new base();
can u people tell me diffence from the above examples.
THANKS.
ANANDA

When you create a new object you have to supply the class to which that
object belongs. A class can extend from another class. If it does so
explicitly you can define the 'parent' class from which the class extends.
If you don't explicitly mention anything, the class will implicitly extend
from the absolute base class named 'Object'.
Your example is a bit convoluted: when you create a Derived object,
its constructor creates another object, i.e. an object from the class from
which the Derived class extends.
Extending from a class and creating an object don't have much in common.
kind regards,
Jos

What is the diffrence between package javax.sql and java.sql

Is javax designed for J2EE?
And when to use package javax?

Hi,
What is the diffrence between package javax.sql and java.sql?The JDBC 2.0 & above API is comprised of two packages:
1.The java.sql package and
2.The javax.sql package.
java.sql provides features mostly related to client
side database functionalities where as the javax.sql
package, which adds server-side capabilities.
You automatically get both packages when you download the JavaTM 2 Platform, Standard Edition, Version 1.4 (J2SETM) or the JavaTM 2, Platform Enterprise Edition, Version 1.3 (J2EETM).
For further information on this please visit our website at http://java.sun.com/j2se/1.3/docs/guide/jdbc/index.html
Hope this helps.
Good Luck.

What is the diffrence between My Runnable Interface and Java Runnable

Hi folks
all we know that interfaces in java just a decleration for methods and variables.
so my Question is why when i create an interface its name is "Runnable" and i declared a method called "run" inside it.then when i implements this interface with any class don't do the thread operation but when i implement the java.lang.Runnable the thread is going fine.
so what is the diffrence between My Runnable Interface and Java Runnable?
thnx

Hi folks

with any class don't do the thread operation but when
i implement the java.lang.Runnable the thread is going
fine.
so what is the diffrence between My Runnable Interface
and Java Runnable?
thnxClasses and interfaces are not identified by just their "name", like Runnable. The actual "name" the compiler uses is java.lang.Runnable. So even if you duplicate the Runnable interface in your own package, it's not the same as far as the compiler is concerned, because it's in a different package.
Try importing both java.util.* and java.awt.* (which both have a class or interface named List), and then try to compile List myList = new ArrayList();

What is the diffrence between a blanket PO and a Framework order?

What is the diffrence between a blanket PO and a Framework order?

Hi
You have to use document type Frame work order for Blanket PO.
You can use blanket purchase orders to procure consumable materials or services for which it is not worth creating a separate purchase order for each procurement transaction.
Blanket purchase orders are usually valid for a longer period of time. You can directly post the invoices for the materials and services procured for this blanket purchase order.

What is the diffrence between a javabean and EJB

hi!
what is the diffrence between a javabean and entreprise jvaabeans! i mean which are the uitilization featires of eaxh one !

i am seeking for a solution for my problem , in fact i ma trying to implement and develop an application with java that allows a certain range of IP adresses to be connected to a database server in order to extract the suitable data from the server .
let me explain mor ethe suitation , in fact what i am loking for is to use javabeans to grant my application much more consistence and pertinence : si i am asking if it could be possible to use javabeans in my case especially if i am not trying to developp a web application but a cleint /server one allowing some services.
The application is in fact dealing with a stock exchange market and what i am trying to do is to grant particilar registrated customers to have the informations that they need ( portofolio, currency's status, market indicators, .) also drawing some charts decribing rates, variations, and others specefic financial caracterestics .So , if we consider that this application is not a web application ( no HTTP request and no servers like apache or others ) how it is possible to use javabeans and not EJB to build the application? i mean what could be suitable and preferable to rely on and dvelop to ensure a good java application !!
if you need more details to help you find the answer for me don't hesitate to answer me back !!
Someone here gave me that answer
use RMI to code the services and (Updateable) Value Objects to pass the information between tiers.
RMI is an all-java distributed component framework (ie. EJB, CORBA, DCE/RPC, DCOM, etc.), that is very suitable for developing non-containerized multi-tier applications. Refer to the RMI trail in the Java Tutorial as a starting point for coding RMI solutions (http://java.sun.com/docs/books/tutorial/index.html). Under this scenario you would code the database access service as an RMI service (server-side). Client/server communication should be facilitated through the use of JavaBeans/classes that wrap the information being passed (customer information, portfolio details, market information, etc.) - these are refered to as 'Updateable Value Objects' (a design pattern). Graphing and charting would be handled in your client from the information received from the (RMI) server. GUI JavaBeans can be used to provide this functionality as well as other client-side services. There are numerous "shrink-wrapped" components for GUIs available on the market just peruse any Java magazine to find them.
but how comes? how can i do it !! and where can i find more information please about 'Updateable Value Object "
thanks

What is the diffrence between K7T266 Pro and Pro2?

What is the diffrence between the pro and the pro 2, besides the pro2 being red and having the link lights. Upto what CPU and what type can the pro 1.0 handle? Also, can it be moded to fit a better cpu? Anyone know?
-Nick

Pro has the KT266 chipset
Pro2 has the KT266A chipset
KT266A has improvements that increase performance, and the Pro2 can be modified to fit Thoroughbred CPUs.
The Pro (KT266) can only accept up to the Athlon 2000+ palomino. Also, overclocking the FSB disables USB; this was fixed with the KT266A.

What is the diffrence between SAP View and CAD View ?

What is the diffrence between SAP View and CAD View ?
What is the main purpose of SAP View
and
What is the main purpose of CAD View
On SAP help i found
SAP View is used for :The SAP view displays the SAP structure (document-based structure) for the active CAD object, or another document info record (header document), with a single-level or multilevel document structure in a tree structure. You can variably configure the fields using the layout editor.
CAD View is used for :The CAD view displays the document-based structure of the currently active CAD object, such as the structure of an assembly. The CAD system determines the complete (multilevel) structure and copies it either completely or in stages to the SAP system, in accordance with the default explosion level.
BUT I did not understand it well
Can someone explain this with an example
THanks
Raj

Hello Raj,
SAP View can be further described as the view that is based on what is existing already in the SAP system. This view is generally used by SAP purchasing, MM people etc
CAD view is nothing but the replication of the model tree view in the SAP system. This is used by the design engineer and this view replicates only the parts that are actively displayed on the CAD tool window.
hope this helps. Let me know if you have further questions else please close the message.

What is the Diffrence between Adaptive and Webi Job Server

Hello,
What is the diffrence between Adaptive Job server and Webi Job server?
In my BO server we didn't have Webi Job server but we are able to schedule the webi reports successfully.
Any Idea on this.
Thanks,
Nimesh.

I believe the Adaptive Job Server is on a generic shell server that behave as a Webi Job Server when it processes webi reports, as a program job server when it processes program object etc.

What is the diffrence between PGA and UGA?

Hi All
Just one question
"What is the diffrence between PGA and UGA?"
Thanks

PGA Memory
The Program Global Area (PGA) is a memory region that contains data and control information for a single process (server or background). The PGA is made up of the following:
Stack Space
A PGA always contains a stack space, which is memory allocated to hold a session's variables, arrays, and other information.
Session Information - (UGA)
A PGA in an instance running without the multi-threaded server (named Shared Server in Oracle9i) requires additional memory for the user's session, such as private SQL areas and other information. If the instance is running the multi-threaded server, this extra memory is not in the PGA, but is instead allocated in the SGA (the Shared Pool).
Shared SQL Areas
Shared SQL areas are always in shared memory areas of the SGA (not the PGA), with or without the multi-threaded server.
Non-shared and Writable
The PGA is a non-shared memory area to which a process can write. One PGA is allocated for each server process; the PGA is exclusive to a server process and is read and written only by Oracle code acting on behalf of that process.
UGA Memory
The UGA, or User Global Area, is allocated in the PGA for each session connected to Oracle in a dedicated server environment. The PGA is memory allocated at the client to hold a stack which contains all of the session's variables, etc. In a Shared Server environment, Oracle allocates this memory in the Shapred Pool (the shared pool is contained in the SGA), for all sessions. This helps to reduce the PGA (client) memory footprint of Oracle, but will increase the SGA (shared pool) requirements.
