Difference between LockSupport.parkUntil and Thread.sleep method

Hi
Could someone please explain the difference between LockSupport.parkUntil and Thread.sleep methods.
Thanks in advance.

javaLearner wrote:
The thing that I am trying to understand is - the difference / correlation between the two methods mentioned.
In the javadoc, there is a mention of correlation between the LockSupport methods park, unpark and the Thread methods suspend, resume - but not park and sleep.Then that suggests that there isn't any difference /correlation -- whatever you meant by that. Perhaps your question is like asking for the difference between a fish and a bicycle.
Also, I would like to understand the statement
These methods are designed to be used as tools for creating higher-level synchronization utilities, and are not in themselves useful for most concurrency control applications. (from the javadoc)Again, you're going to have to explain what you don't understand about it.

Difference between Application.CurrentCulture and Thread.CurrentCulture

Can someone tell me the difference between Application.CurrentCulture and Thread.CurrentCulture.
Thread has CurrentCulture and CurrentUICulture. But Application has only CurrentCulture. Why?
(https://msdn.microsoft.com/en-us/library/system.windows.forms.application.currentculture(v=vs.110).aspx)
(https://msdn.microsoft.com/en-us/library/system.threading.thread.currentculture(v=vs.110).aspx)

1)
Application.CurrentCulture delegates to Thread.CurrentThread.CurrentCulture("Gets or sets the culture information for the current thread") so it only sets it for the main thread of the
application.
2) They are both properties of a Thread object, which you can access via Thread.CurrentThread.
CurrentCulture – Tells you the user’s current locale, as set in the Region
applet. I.e.: Where is the user located?
CurrentUICulture – Tells you the native language of the version of Windows
that is installed. I.e.: What language does the user speak?
The user can change CurrentCulture using the Region applet. It’s used to determine formatting for numeric and date/time
strings.

Difference between co-routine and thread?

hi,
i keep bumping into people who talk about co-routines? does anyone know if there is any difference between this and a thread (internet definitions don't seem to suggest so..), if there is no difference is this just a historical term? is it tied to any particular platform/language?
thanks,
asjf

i keep bumping into people who talk about co-routines?How old were they? -:) The term is mix betweenvconcurrent and subroutine. A co-routine starts running
in its own thread when called.Its own thread you say? Luxury! Pure luxury! Coroutines existed before multiple threads existed.
All coroutines were marked 'runnable' at startup and when one (and the only) running coroutine wanted
to relinguish control of the processor it had to say so explicitly by calling some 'yield' command.
This command was the entry point to a primitive scheduler that randomly picked another runnable
coroutine; the latter had to 'yield' somewhere in the near future to keep the whole shebang running.
In those days there were no multiple threads; Luxury! Pure modern luxury! And in those days computers
were made of wood and I am not old! ;-)

Jos ( <--- not old )

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.

Sruthi

Difference between v$instance and v$thread

Hallo,
What is the difference between v$instance and v$thread?
Thanks,

Well, a mere description of the views in the official documentation isn't going to actually help you very much more than you could do with a simple "desc V$instance/desc V$thread", I suspect.
The answer I think you might be looking for is that a thread is not the same thing as an instance. In fact, we usually talk about "a thread of redo", which gets much closer to the issue here. Yes, it is true that one instance can only generate one 'thread of redo', so one instance = one thread, and there's a temptation to extrapolate from that and assume they're the same thing.
But they're not. An instance is a set of memory structures and processes. It has a name. It gets started and stopped. In can be running in various states (nomount, mount, open, read-only, primary, secondary etc).
A thread of redo is a history of redo generated by an instance. It has ever-incrementing checkpoint change numbers, times of last checkpoints, sequence numbers, blocks of redo that are forever being flushed to different parts of the current redo log. And so on.
Thus, V$INSTANCE tells you the state of the instance and V$THREAD tells you all you could ever want to know about where you're up to in the writing-redo stakes.

Difference between Snapshot scenario and non cumulative scenario

Hi,
Can any one please tell me the difference between snapshot scenario and non cumulative scenario in
inventory management.
Also please give example. I read the pdf " how to handle inventroy management scenarios", but can any one please give some easy to understand examples.
full points guaranteed-

hi,
In Non-cummulative method your stock movements are stored in the cube (inflow and outflow of NC KF) and the Total stock is calculated during query execution. Hence if there are lot of movements in the stock for the period you want to report on, query will take long time to execute.
In case of Snap shot scenario Stock movements are not loaded to cube. you use ODS to load the status of the stock and then from ODS you can load to Cube once in a month. So only summarized data will be availabe in Cube. Reporting will be fast.

Difference between Item Cost and Last Evaluated Price

Dear All,
What is the difference between Item Cost and Price in Last Evaluated Price List. Exactly when are they updated?
Regards
Sibasish

Hi Sibasish,
The "Last Evaluated Price" is simply a price list but can't have a direct manipulation like other price lists. Its values may not involve in any accounting transactions if it's not selected for the concerned transaction any way.
On the other hand the item cost is the cost which is maintained by SAP B1 (until and unless you select the Standard Valuation Method), and it gets involved in the accounting transactions where inventory is involved. For e.g. the "COGS" is calculated on the basis of this value.
Please close this thread if answered ... or please let us hear something more from you on this...

Difference between Search Helps and Match Codes?

Difference between Search Helps and Match Codes?

Serch help
Search Helps
The input help (F4 help) is a standard function of the R/3 System. The user can display the list of all possible input values for a screen field with the input help. The possible input values can be enhanced with further information. This is meaningful especially when the field requires the input of a formal key.
Standard Input Help Process
A user calls an input help with the following steps (some steps can be omitted, depending on the definition of the input help):
The user starts the input help to display the possible input values for a field (search field) in a screen template.
The system offers the user a number of possible search paths. The user selects one of these search paths. Each search path offers a number of restrictions to limit the number of possible input values. These values are offered in a Dialog box for value restriction when the search path is selected.
The user enters restrictions if required and then starts the search.
The system determines the values that satisfy the entered restrictions (hits) and displays them as a list (hit list).
The user selects the most suitable line from the hit list by double-clicking.
The value of the search field is returned to the screen template (possibly together with other values).
Steps 2 and 3 are omitted if there is only a single search path available. In this case the dialog box for the value selection is offered immediately. You can also output the hit list directly after starting the input help. Steps 2 to 4 are omitted in this case.
Function of a Search Help
This standard process can be completely defined by creating a search help in the ABAP Dictionary. This search help only has to be assigned to the screen fields in which they should be available (see Attaching Search Helps to Screen Fields).
There are two types of search help:
Elementary search helps describe a search path. The elementary search help must define where the data of the hit list should be read from (selection method), how the exchange of values between the screen template and selection method is implemented (interface of the search help) and how the online input help should be defined (online behavior of the search help).
Collective search helps combine several elementary search helps. A collective search help thus can offer several alternative search paths.

Match code
Match code is nothing but the Search help in Higher versions
It is same way from SE11 you have to create.
so from SE11 create it and use it.
Matchcode objects are being replaced by search helps. This is good as search helps are easy to create. However, it has caused some confusion on how best to add search helps to a selection field.
The trick that I found is to keep your newly created search helps to a 4-character name. The Matchcode object name has this old 4-character limit. This trick is not documented anywhere in the system but it has been a great time saver for me. You can expand this concept by finding existing SAP search helps that are more than 4-characters, copy them to a 4-character name and presto, you have a new matchcode object available for use

Try to repeat this using a function group and I think you'll undestand because it'll be very hard to do it.
By only one function group how can u read the data of a certain vehicle?
Yes you can create in the function group an internal table where u store the data of every car: in this way u use the internal table like it was an instance, but you should consider here the example is very simple. Here we have only the speed as characteristic, but really we can have many complex characteristics.

What is the difference between jsp :include and server side include

what is the difference between jsp :include and server side include(request dispatcher include method)????
i understand that both request dispatcher include method and jsp:include take dynamic data,so when would one use request dispatcher include and when jsp:include.
Is the usage interchangeable?i believe jsp include is used only for jsp/html but include directive can be used to include servlets ,jsp and html....correct me if i m wrong and
do suggest if u hav ny other diff in this context...

The difference really is: in what format do you want your inclusions? If your environment has many Java developers and only a few designers that focus mainly on, say, Flash, that might push you more towards the server-side include() directive. Or, if you have a large set of pages that receive dynamic content that is displayed in a consistent fashion (such as a workflow header area on a page).
If, on the other hand, you have more web designers, there may be a greater desire to deal in markup rather than Java code. Java developers themselves might prefer to view markup (JSP) that more resembles the eventual output than something occuring in Java code.
Finally, there are considerations of tiering. While it is totally possible to (and I have previously) implement 'view classes' that render markup or generate layout templates, JSP's offer, IMO, a subtle, psychological advantage. By forcing a developer to work in a different format, markup versus Java source, the separation on view from controller and model becomes a bit easier. It is still possible to make mistakes, but if a developer at some point notices, "Wait, I'm in a JSP, should I be importing a java.sql class?", then the choice to use JSP includes has paid off in spades.

Difference between Return Po and Retuning with 122 movement type

Dear Experts,
i need some clarification on Return Po and retuning goods with 122 movement type in the context of Excise invoice.
in our previous company we used 122 movement we capture excise invoice with J1IS and referring the incoming excise
and return the material to vendor.
in present company we are directly doing return Po and capturing excise invoice with J1is,here we are not capturing against the
incoming excise,please clarify me.
Regards,
Varun

Hi,
Refer the below thread:
Difference between 102, 122 and 161
In terms of stock movement, both 122 and 161 represents the return delivery to your vendor. The difference takes place in terms of how you are returning your delivery to your vendor - It is movement type 161 that SAP will automatically propose if your return PO is referenced. Otherwise, 122 movement type will be used instead.

Difference between Interface node and normal node?

What is the main difference between Interface node and normal node?
Cheers
Aisurya.

Hi surya,
Interface node or methods comes into picture whenever you want to use one component as used component. I mean to say
Component usages. If you select node as interface node, it will available in another component so you can use that node or methods.
Normal node means in that component only. Simply we can say for component usages we go for interface nodes.
