Difference between Naming.lookup and Registry.lookup in RMI

Hi Folks,
I have an RMI client which tries to look up a remote object using both
Naming.lookup("//host[:port]/name OR rmi://<host_name>[:<name_service_port>]/<service_name>") and LocateRegistry.getRegistry().lookup("rmi://<host_name>[:<name_service_port>]/<service_name>").
The first one fails whereas the second one succeeds. I am in a fix as to why it is so.Is there any difference between the lookup methods provided by Naming and Registry?
The remote object was registered on the server using
LocateRegistry.createRegistry().rebind("rmi://<host_name>[:<name_service_port>]/<service_name>").

I suggest you take a look at this site to understand how to ask questions.

Which is the difference between a join and a lookup key

Hello everybody,
I want to know in which case we must use a join or a lookup key.
How OWB translate this two orders ?
If you want more information, ask me.
Best regards,
Chris

Hi,
In a normal mapping, you can use a Key Lookup operator or a joiner. The Key Lookup operator operates as an outer join. You can use a joiner instead of a Key Lookup operator with the join condition specified with outer joins.
In my view, use joiner with the lookup condition specified in outer join. Using keu lookups, in a complicated mapping can lead to the following error at runtime:
"A table can be outer joined with atmost one other table".
Apart from this, I think Key Lookups are generally useful in dimension lookups in a datawarehouse, where you can specify the level where you should search for a match. The 10g R2 user's guide provides the details on how to do this.

Difference between primary key and primary index

Dear All,
Hi... .Could you pls tell me the difference between primary key and primary index.
Thanks...

Hi,
Primary Key : It is one which makes an entry of the field unique.No two distinct rows in a table can have the same value (or combination of values) in those columns.
Eg: first entry is 111, if you again enter value 111 , it doesnot allow 111 again. similarly for the strings or characters or numc etc. Remember that for char or numc or string 'NAME' is not equal to 'name'.
Primary Index: this is related to the performance .A database index is a data structure that improves the speed of operations in a table. Indices can be created using one or more columns, providing the basis for both rapid random lookups and efficient ordering of access to records. The disk space required to store the index is typically less than the storage of the table (since indices usually contain only the key-fields according to which the table is to be arranged, and excludes all the other details in the table), yielding the possibility to store indices into memory from tables that would not fit into it. In a relational database an index is a copy of part of a table. Some databases extend the power of indexing by allowing indices to be created on functions or expressions. For example, an index could be created on upper(last_name), which would only store the uppercase versions of the last_name field in the index.
In a database , we may have a large number of records. At the time of retrieving data from the database based on a condition , it is a burden to the db server. so whenever we create a primary key , a primary index is automatically created by the system.
If you want to maintain indices on other fields which are frequently used in where condition then you can create secondary indices.

What is the difference between ejb reference and ejb handle?

Hi:
I am newbie for J2EE.
I want to know what is the difference between ejb reference and ejb handle
from the client view and from the container view?
Very Thanks!
Stive

Hi John,,
1) Ejb Object Handle are nothing but a long lived proxy for the
ejb object, using this handle user can disconnect from the Ejb Server/Container
at any time
and after some time using the same handle he can able to resume the conversational
state
with the server / container where he was been disconnected From.
And there are currently two Handles , HomeHandle and Handle for EjbHomeObject
and EjbObject
Respectively. Both these handles have Persistent reference to the EJB Object
2) Ejb Reference is used to lookup a bean from other Enterprise Bean
Ejb reference is a nickname for the JNDI Location that you want to lookup a bean.
your code will looks up a Home object via using this nickname
and the deployer will bind the
nickname to the JNDI location of its choice
EJb Reference are declared in the deployment descriptor

The difference between system restore and last good known configuration

hi,
what is the difference between system restore and last good known configuration.
in which situation you use system restore ,and in which situation you use last good known configuration.
very short answer wil be enough.
thanks
johan
h.david

Last Known Good Configuration deals only with Starting Windows eg. a bad registry or incorrect driver is preventing Windows to start.It recovers the registry settings of HKEY_LOCAL_MACHINE\System\CurrentControlSet
While System Restore uses restore points to return your system files and settings to an earlier point in time without affecting personal files. Restore points are created automatically every week, and just before significant system events, such as the installation
of a program or device driver. You can also create a restore point manually.You can undone system restore but there is no such option in Last Known Good Configuration.
Last Known Good Configuration is disabled in Windows 8 or,Windows 8.1 by default.
Try using Last Known Good Configuration if you can't start Windows, but it started correctly the last time you turned on the computer.
Try using System Restore to return the system to an earlier point in time when things worked correctly.

What is difference between table space and shchema

what is difference between table space and shchema ?

784633 wrote:
so each user has it own space of tables - schema ?yes, but let's clarify a bit ....
The "schema" is the collection of all objects owned by a particular user. So if user SCOTT creates two tables, EMP and DEPT, and a view EMP_RPT, and a procedure GET_MY_EMP, those objects (tables, views, procedures) collectively make up the SCOTT schema.
Those objects will be physically stored in a tablespace.
A tablespace is a named collection of data files. So tablespace USERS will be made up of one or more data files. A specific datafile can belong to one and only one tablespace. If a tablespace has more than one data file, oracle will manage those files as a collection invisible to the application - much like the OS or disk subsystem handles striping across multiple physical disks.
A specific object in the SCOTT schema can exist in only one tablespace, but not all objects of the schema have to be in the same tablespace. Likewise a tablespace can contain objects from multiple schemas.
and can one user to access tables of other users?As others have said - FRED can access tables belonging to SCOTT as long has SCOTT has granted that access to FRED.

What is difference between 32 bit and 64 bit sql server memory management

What is difference between 32 bit and 64 bit sql server memory management
Thanks
Shashikala

This is the basic difference...check if helps:
A 32-bit CPU running 32-bit software (also known as the x86 platform) is so named because it is based on an architecture that can manipulate values that are up to 32 bits in length. This means that a 32-bit memory pointer can store a value between 0 and
4,294,967,295 to reference a memory address. This equates to a maximum addressable space of 4GB on 32-bit platforms
On the other hand 64-bit limit of 18,446,744,073,709,551,616, this number is so large that in memory/storage terminology it equates to 16 exabytes. You don’t come across that term very often, so to help understand the scale, here is the value converted to
more commonly used measurements: 16 exabytes = 16,777,216 petabytes (16 million PB)➤ 17,179,869,184 terabytes (17 billion TB)➤ 17,592,186,044,416 gigabytes (17 trillion GB)➤
As you can see, it is signiﬁcantly larger than the 4GB virtual address space usable in 32-bit systems; it’s so large in fact that any hardware capable of using it all is sadly restricted to the realm of science ﬁction. Because of this, processor manufacturers
decided to only implement a 44-bit address bus, which provides a virtual address space on 64-bit systems of 16TB. This was regarded as being more than enough address space for the foreseeable future and logically it’s split into an 8TB range for user mode
and 8TB for kernel mode. Each 64-bit process running on an x64 platform will be able to address up to 8TB of VAS.

Difference between NetWeaver 2004 and NetWeaver 7.0 or 7.1

I am little confused and curious to know the recent changes happening in SAP.
Can you please tell me the differences between NetWeaver 2004 and NetWeaver 7.0 or 7.1
NetWeaver 2004 is named because SAP has released it in 2004
and then we have XI 3.0, XI.7.0(that is PI right) , EP6.0 etc as individual components have different versions released in NewtWeaver suite.
But what is this NetWeaver 7.0.
We have EE5 or ECC6 and WebAs 6.4 or GUI 6.4 or recently GUI 7.o or WebAs 7.0.
How does all these differe, is individual component of NetWeaver upgraded with higher versions or total NetWever is upgraded with a higher version.
Can any one please tell me the exact difference between versions.
If some one has ECC6 installed in their environment does it mean that they have Netwaver components like XI, EP, MDM.. etc are installed or its only R/3, BI etc...
How it works exactly?
Thanks,
Kiran.

Question about main difference between Java bean and Java class in JSP

Hi All,
I am new to Java Bean and wonder what is the main difference to use a Bean or an Object in the jsp. I have search on the forum and find some post also asking the question but still answer my doubt. Indeed, what is the real advantage of using bean in jsp.
Let me give an example to illustrate my question:
<code>
<%@ page errorPage="errorpage.jsp" %>
<%@ page import="ShoppingCart" %>

<jsp:useBean id="cart" scope="session" class="ShoppingCart" />
<html>
<head><title>Shopping Cart</title></head>
<body bgcolor="#FFFFFF">
Your cart's ID is: <%=cart.getId()%>.
</body>
<html>
</code>
In the above code, I can also create a object of ShoppingCart by new operator then get the id at the following way.
<code>
<%
ShoppingCart cart = new ShoppingCart();
out.println(cart.getId());
%>
</code>
Now my question is what is the difference between the two method? As in my mind, a normal class can also have it setter and getter methods for its properties. But someone may say that, there is a scope="session", which can be declared in an normal object. It may be a point but it can be easily solved but putting the object in session by "session.setAttribute("cart", cart)".
I have been searching on this issue on the internet for a long time and most of them just say someting like "persistance of state", "bean follow some conventions of naming", "bean must implement ser" and so on. All of above can be solved by other means, for example, a normal class can also follow the convention. I am really get confused with it, and really want to know what is the main point(s) of using the java bean.
Any help will be highly apprecaited. Thanks!!!
Best Regards,
Alex

Hi All,
I am new to Java Bean and wonder what is the main
difference to use a Bean or an Object in the jsp. The first thing to realize is that JavaBeans are just Plain Old Java Objects (POJOs) that follow a specific set of semantics (get/set methods, etc...). So what is the difference between a Bean and an Object? Nothing.
<jsp:useBean id="cart" scope="session" class="ShoppingCart" />
In the above code, I can also create a object of
ShoppingCart by new operator then get the id at the
following way.
ShoppingCart cart = new ShoppingCart();
out.println(cart.getId());
...Sure you could. And if the Cart was in a package (it has to be) you also need to put an import statement in. Oh, and to make sure the object is accessable in the same scope, you have to put it into the PageContext scope. And to totally equal, you first check to see if that object already exists in scope. So to get the equivalant of this:
<jsp:useBean id="cart" class="my.pack.ShoppingCart"/>Then your scriptlet looks like this:
<%@ page import="my.pack.ShoppingCart %>
<%
ShoppingCart cart = pageContext.getAttribute("cart");
if (cart == null) {
    cart = new ShoppingCart();
    pageContext.setAttribute("cart", cart);
%>So it is a lot more work.
As in my mind, a normal class can also
have it setter and getter methods for its properties.True ... See below.
But someone may say that, there is a scope="session",
which can be declared in an normal object.As long as the object is serializeable, yes.
It may be
a point but it can be easily solved but putting the
object in session by "session.setAttribute("cart",
cart)".Possible, but if the object isn't serializable it can be unsafe. As the point I mentioned above, the useBean tag allows you to check if the bean exists already, and use that, or make a new one if it does not yet exist in one line. A lot easier than the code you need to use otherwise.
I have been searching on this issue on the internet
for a long time and most of them just say someting
like "persistance of state", "bean follow some
conventions of naming", "bean must implement ser" and
so on. Right, that would go along the lines of the definition of what a JavaBean is.
All of above can be solved by other means, for
example, a normal class can also follow the
convention. And if it does - then it is a JavaBean! A JavaBean is any Object whose class definition would include all of the following:
1) A public, no-argument constructor
2) Implements Serializeable
3) Properties are revealed through public mutator methods (void return type, start with 'set' have a single Object parameter list) and public accessor methods (Object return type, void parameter list, begin with 'get').
4) Contain any necessary event handling methods. Depending on the purpose of the bean, you may include event handlers for when the properties change.
I am really get confused with it, and
really want to know what is the main point(s) of
using the java bean.JavaBeans are normal objects that follow these conventions. Because they do, then you can access them through simplified means. For example, One way of having an object in session that contains data I want to print our might be:
<%@ page import="my.pack.ShoppingCart %>
<%
ShoppingCart cart = session.getAttribute("cart");
if (cart == null) {
    cart = new ShoppingCart();
    session.setAttribute("cart", cart);
%>Then later where I want to print a total:
<% out.print(cart.getTotal() %>Or, if the cart is a JavaBean I could do this:
<jsp:useBean id="cart" class="my.pack.ShoppingCart" scope="session"/>
Then later on:
<jsp:getProperty name="cart" property="total"/>
Or perhaps I want to set some properties on the object that I get off of the URL's parameter group. I could do this:
<%
ShoppingCart cart = session.getAttribute("cart");
if (cart == null) {
    cart = new ShoppingCart();
    cart.setCreditCard(request.getParameter("creditCard"));
    cart.setFirstName(request.getParameter("firstName"));
    cart.setLastName(request.getParameter("lastName"));
    cart.setBillingAddress1(request.getParameter("billingAddress1"));
    cart.setBillingAddress2(request.getParameter("billingAddress2"));
    cart.setZipCode(request.getParameter("zipCode"));
    cart.setRegion(request.getParameter("region"));
    cart.setCountry(request.getParameter("country"));
    pageContext.setAttribute("cart", cart);
    session.setAttribute("cart", cart);
}Or you could use:
<jsp:useBean id="cart" class="my.pack.ShoppingCart" scope="session">
<jsp:setProperty name="cart" property="*"/>
</jsp:useBean>The second seems easier to me.
It also allows you to use your objects in more varied cases - for example, JSTL (the standard tag libraries) and EL (expression language) only work with JavaBeans (objects that follow the JavaBeans conventions) because they expect objects to have the no-arg constuctor, and properties accessed/changed via getXXX and setXXX methods.

Difference between EDN-DB and EDN-JMS implementation

Experts,
Looking for a difference between EDN-DB and EDN-JMS implementation. We have EDN implementation going on, where multiple source systems will be publishing business events. Events can be published using SOA Suite or JMS Bridge from AQ and MQ. In this scenario which implementation approach is suited better ?

Oracle Apps Adapter can be used for many other products other than E-Business Suite (JD Edwards E1, OTM, and others). The apps adapter was mainly used in ERP systems and was strong when you needed have added functionality other than just polling a db for a status / calling a stored procedure... It could connect out to other business services, xml gateways and so-on.
From a technical aspect / development perspective I always thought of that the Oracle Apps Adapter simplifies the development but, may is not flexible. The App Adapter's strength is the services that are difficult to integrate with (business services, xml gateway). If you need to hook in to these types of services, use the APPS adapter. (Again like it is named the "Apps Adapter" its for interacting w/ other applications to enable real-time processing / functionality.
That being said the dbAdapter can be very powerful but, like it is named is database focused (to poll some table to know when to kick off other logic and enable real-time functionality through database interaction.
Looking at the Oracle 12C Roadmap I had heard that there is more planned for the Oracle Apps Adapter moving forward, especially as Anuj said in the "Financial Apps" side of the isle at Oracle. Who knows what is real and what isn't though =]
Hope this helps!

Difference between At new and on change statement?

What is the difference between at new and on change statement? Please explain with an example.

hi
on change of differs from at new in the following respects:
It can be used in any loop construct, not just loop at. For example, it can be used within select and endselect, do and enddo, or while and endwhile, as well as inside get events.
A single on change of can be triggered by a change within one or more fields named after of and separated by or. These fields can be elementary fields or field strings. If you are within a loop, these fields do not have to belong to the loop.
When used within a loop, a change in a field to the left of the control level does not trigger a control break.
When used within a loop, fields to the right still contain their original values; they are not changed to contain zeros or asterisks.
You can use else between on change of and endon.
You can use it with loop at it where . . ..
You can use sum with on change of. It sums all numeric fields except the one(s) named after of.
Any values changed within on change of remain changed after endon. The contents of the header line are not restored as they are for at and endat.

Difference between analytic privilege and package privilege

Hello Team
Please suggest me on the difference between Analytic privilege and package privilege . Since both the privileges works on package only . So what is the exact difference between them .
Regards

Hi,
SAP HANA have several categories of privileges such as system privileges, object privileges, analytic privileges, package privileges and application privileges.
For analytic privileges and package privileges, they are very different.
When you use analytic privileges, you can grant different users to see different data. For example you have an analytic view including some sales data and there is a column LOCATION. You can use analytic privilege to grant the sales in the east US to only see the sales data where LOCATION = "EAST" and grant the sales in the west US to only see the sales data where LOCATION = "WEST". This is just a simple example. In short, you use analytic privileges to grant different users to see different data.
Regarding package privilege, when you develop on XS projects, you can grant different package privileges to different users. For example, you have a package named "services" in your XS project. You can use package privilege to grant user A to only read the content under "services" and grant user B to edit/activate or even delete the "services" packages.

Difference between function module and a method?

Hi Experts
Can anybody pls tell me the technical and functional difference between function moduel and a method?
Thanks
Sudhansu

Hi,
Function modules are procedures that are defined in function groups (special ABAP programs with type F) and can be called from any ABAP program. Function groups act as containers for function modules that logically belong together. You create function groups and function modules in the ABAP Workbench using the Function Builder.
Function modules allow you to encapsulate and reuse global functions in the R/3 System. They are stored in a central library. The R/3 System contains a wide range of predefined function modules that you can call from any ABAP program. Function modules also play an important role in database updates and in remote communications between R/3 Systems or between an R/3 System and a non-SAP system.
You can declare methods in the declaration part of a class or in an interface. To declare instance methods, use the following statement:
METHODS <meth> IMPORTING.. [VALUE(]<ii>[)] TYPE type [OPTIONAL]..
               EXPORTING.. [VALUE(]<ei>[)] TYPE type [OPTIONAL]..
               CHANGING.. [VALUE(]<ci>[)] TYPE type [OPTIONAL]..
               RETURNING VALUE(<r>)
               EXCEPTIONS.. <ei>..
When you declare a method, you also define its parameter interface using the additions IMPORTING, EXPORTING, CHANGING, and RETURNING. The additions define the input, output, and input/output parameters, and the return code. They also define the attributes of the interface parameters, namely whether a parameter is to be passed by reference or value (VALUE), its type (TYPE), and whether it is optional (OPTIONAL, DEFAULT).
Unlike in function modules, the default way of passing a parameter in a method is by reference.
As in function modules, you can use exception parameters (EXCEPTIONS) to allow the user to react to error situations when the method is executed.
As in function modules, you can use the RAISE <exception> and MESSAGE RAISING statements to handle error situations.
