What's the difference between dot sourcing and non-dot sourcing?

My teacher is incompetent in this matter.
I've been struggling to make logic out of the use of dot-sourcing and non dot sourcing.
What is the difference? I've been bashing my head against the wall for the past hour.

Hi Loginux,
"simply" put, non-dotsourcing scripts / functions will run them in their own small box ("Scope"), which is discarded when the execution finishes. Dotsourcing will run it in the current environment. Example:
script.ps1:
$Hello = "Hello World"
non-dotsourced:
$Hello = "Hi Mark"
& .\script.ps1
Write-Host $Hello
dotsourced:
$Hello = "Hi Fred"
. .\script.ps1
Write-Host $Hello
Cheers,
Fred

What is the difference between buffered acquisition and non buffered acquisition?

What is the difference between buffered acquisition and non buffered acquisition? How will I decide whether I want buffered acquisition or non buffered acquisition?

I will also add that with non buffered acquisition you have to use software timing. Windows is not a real time OS, so the the timing is not accurate. But if you use buffered acquisition the timing will be controlled with an accurate internal clock on the Daq unit. I think non buffered acquisition should be avoided in most cases.
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

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.

What is the difference between Category Mgmt and Spend Analysis?

Hi Friends
What is the difference between Category Mgmt and Spend Analysis?
Regards
Chinna Krishna

Hi Chinna
Here are my two cents on this questions
1. Catagory Management : It pertains to all sourcing activities that a purchasing group does for a specific catagory of items ( say tyres, bearings, etc. in automobile industry scenario OR steel sheets, electric motor, etc. in consumer durables industry scenario) in order to meet companies strategic goals like cost, quality, delivery and new product introduction. It also involves the strategic sourcing piece for that category. Typically it can include following activities for a category which is being managed
- Identifying current and future business & technical requirements
- Constant vigilence and analysis of supply market for that category ( and also identifying new sources)
- Lauching various projects within category focussed on cost reduction, quality improvement, delivery improvement. This may include some of activities like supplier analysis. RFx, Reverse auctions, contract negotiation, etc.
- Monitoring the category specific supplier performance
Category Management team typically consists of cross functional team and it is iterative process (continuous improvement).
Category Management in covered to some extent in E-Sourcing application and its analysis is covered in Spend Analytics application. Fully blown category management is on road map of SAP but none of the current functionalities addresses it fully.
2. Spend Analysis: This involves analysis of the spend at highest level of organization. To improve the data quality, it typically involves spend data standardization & enrichment, supplier normalization and spend categorization. Once you have clean data, one can slice and dice the data to gain insight into the spend and identify opportunities for launching the various initiatives focussed on cost, quality and delivery.
SAP Spend Analytics application covers this spend analysis capability.
Its a long answer and hope it helps you.

What is the difference between undo tablespace and online redo log files.

what is the difference between undo tablespace and online redo log files. I am confused
as per my knowledge undo tablespace is used to store the undo information when a table is being updated so that, just incase we need to rollback a transaction we know what was present in the table earlier.
when a transaction fails the SMON performs the rollback of the data.
This undo data is stored in the undo tablespace and read consistency if any is enforced.
is my understanding till here correct?
Now, can this undo data/before image not be stored in the redo log buffer and online redolog files?
can redo-log files not store this information?
in fact, is it that when undo tablespaces exist in a database, the undo data/before image is stored in both the undo tablespace and also the redo log files?
kindly clarify my doubt.
thank you.

This question has been asked many times before. The answer is always the same.
Yes, redo contains the before image of data (and the after-image). Therefore, it **COULD** be used to roll back a transaction.
BUT... Redo is written sequentially. Using it to rollback your transaction would involve reading through all the redo written by maybe thousands of other people. It would be painfully slow.
Your transaction is, however, directly linked to just the UNDO that it generates (which is JUST the before image of the data). So, your undo is your undo and doesn't share space with anyone else's undo. Therefore, using it to roll back YOUR transaction is fast.
The fact that undo is only the before image of the data also makes it faster than wading through a sea of before and AFTER images as you'd find in redo. About twice as fast, in fact, since there's half the data. Roughly.
Redo also gets written and flushed to disk whenever there's a commit, 3 seconds are up or too much (1MB, actually) redo gets generated between flushes caused by other factors. Your redo gets flushed when those things happen, even if you haven't actually committed your transaction. And redo logs recycle themselves, meaning that your redo -even if your transaction hasn't been committed yet- can be over-written by later transactions. Try rolling back when that's happened, if redo was the source of your rollback data!
Undo, however, cannot be over-written if the transaction has not been committed. Ever. If you don't commit for three years, there will be three years' undo stored in your database (assuming you had the space, of course!).
I could go on, but that will do. Redo is there fore RECOVERY, after catastrophe. Undo is there for read-consistency (and the occasional change of mind). Two different functions. Two different mechanisms. Each one highly tuned to doing what it does, why it does it, most efficiently and effectively.

What is the difference between FND_CONC_CLONE.setup_clean and target_clean

What is the difference between fnd_conc_clone.setup_clean and fnd_conc_clone.target_clean?
I always run setup_clean to wipe out all the information carried from source, and then run adautocfg.sh on dbTier followed by appsTeir. This will give me the clean newly cloned ebs system. But what is target_clean for? What is the difference between setup_clean and target_clean;
James

I finally go through the code and actually run the target_clean in our test system. Here is general rule, if you clone the ebs system, you only need to run setup_clean, it will clean out topology information or ebs connection information from the system. Then you run adautocfg.sh on db tier first following by adautocfg.sh on apps tier. All the topology or connection information will be populated again inside the database.
Once you have cloned the system, you do not want any printer setup info, log/out info or profile info carried from source, then you can run target_clean. For me, I do need preserve printer and profile info, so I need to export following 4 tables before running target_clean.
FND_PROFILE_OPTION_VALUES,
FND_PRINTER,
FND_PRINTER_TL,
FND_CONCURRENT_PROGRAMS
Hope this will help.

What is the difference between workbench request and customizing request

hi gurus
can anyone suggest me
what is the difference between
workbench request and
customizing request
abaper ll work on which request
thank you
regards
kals.

A quick search in the forum would have taken you to this answer
Workbench Requests
When you change a Repository object of the ABAP Workbench, a query window appears in which you need to specify a Workbench request. You can only save the changes if you have assigned the object to a change request.
Workbench requests and the tasks assigned to them are normally used to record changes to Repository objects and Customizing for all clients. However, you can also include client-specific Customizing.
Whether the changes to Repository objects are transported depends on whether a transport route is defined from the current SAP System for the package of these objects. From the system settings, the system automatically determines whether the change requests are transportable and to which target system they should be transported.
Customizing requests
Customizing requests record client-specific Customizing settings made in a single client (the source client of the request).
Automatic recording of configuration activities in the Customizing work for a client can be activated or deactivated for each client with Client Control. If automatic recording is active, a query window appears when you change Customizing settings, asking you to specify a Customizing request.
Whether Customizing requests are transported or not, does not depend on the objects entered, as is the case with Workbench change requests. The Customizing requests in an SAP System (or in a client if you use Extended Transport Control) are either all transportable or all local, depending on the system setting. The system uses the standard transport layer to determine automatically whether the change requests are transportable and to which target system they should be transported. However, you can change this manually.

What is the difference between live auction and bid invitation

hi friends
what is the difference between live auction and bid invitation
thanks
regards
vinaykrishna

Source SAP.
BI including Price and non-price variables but LAC Bidding is based on price only.
BI - Longer response time for Bidders (from days to week) but Bidding short bidding windows (Hours).
BI - Bidders sees no information on competitors' bid but in LAC Rank,Best Bid , and next bid can be displayed on real time
BI-Well suited for large variety of goods and services , including ram waterials, services and projects but LAC More suited for commodities or goods and services with standard attributes that vary only slightly from supplier to supplier.
BI -Sourcing is based on value propositions (.eg. High Quality ,fast deliveries) rather than price but LAC market dynamics of auctions work best when buyer/seller relationship is loosele- coupled.

What is the difference between customer exits and user exits?

hello friends,
what is the difference between customer exits and user exits?

Hi
User exit - A user exit is a three character code that instructs the system to access a program during system processing.
SXX: S is for standard exits that are delivered by SAP.   XX represents the 2-digit exit number.
UXX: U is for user exits that are defined by the user. XX represents the 2-digit exit number
Customer exit - The R/3 enhancement concept allows you to add your own functionality to SAPs standard business applications without having to modify the original applications. SAP creates customer exits for specific programs, screens, and menus within standard R/3 applications. These exits do not contain any functionality. Instead, the customer exits act as hooks. You can hang your own add-on functionality onto these hooks.     *-- Mani
The following document is about exits in SAP :-
The R/3 enhancement concept allows you to add your own functionality to SAPs standard business applications without having to modify the original applications.
SAP creates user exits for specific programs, screens, and menus within standard R/3 applications. These exits do not contain any functionality. Instead, the customer exits act as hooks. You can hang your own add-on functionality onto these hooks.
Types of Exits
There are several different types of user exits. Each of these exits acts as hooks where you can attach or "hang" your own add-ons.
Menu Exits
Menu exits add items to the pulldown menus in standard SAP applications. You can use these menu items to call up your own screens or to trigger entire add-on applications.
SAP creates menu exits by defining special menu items in the Menu Painter. These special entries have function codes that begin with "+" (a plus sign). You specify the menu items text when activating the item in an add-on project.
Screen Exits
Screen exits add fields to screens in R/3 applications. SAP creates screen exits by placing special subscreen areas on a standard R/3 screen and calling a customer subscreen from the standard screens flow logic.
Function Module Exits
Function module exits add functions to R/3 applications. Function module exits play a role in both menu and screen exits.
When you add a new menu item to a standard pull down menu, you use a function module exit to define the actions that should take place once your menu is activated.
Function module exits also control the data flow between standard programs and screen exit fields. SAP application developers create function module exits by writing calls to customer functions into the source code of standard R/3 programs.
These calls have the following syntax:
CALL CUSTOMER-FUNCTION 001.
Field Exits
Field exits allow you to create your own programming logic for any data element in the Dictionary. You can use this logic to carry out checks, conversions, or business-related processing for any screen field. Example: The data element BBBNR identifies a companys international location number. You might want to set up your R/3 System so that all international location numbers are larger than 100.
The field exit concept lets you create a special function module that contains this logic.
You assign the special function module to the data element BBBNR. You then assign the module to any programs and screens in which users can add new international location numbers. When you activate your field exit, the system automatically triggers your special routine whenever a user enters a company location number.
In 4.6c, you can use "RSMODPRF" program to create field exits.
An example of a user exits :-
MODULE user_exit_0001 INPUT
    CASE okcode.
        WHEN 'BACK OR EXIT'.
            CASE sy-dynnr.
                    WHEN '100'.
                         SET SCREEN 0.
                         LEAVE SCREEN.
                    WHEN '200'.
                         SET SCREEN 100.
                         LEAVE SCREEN.
             ENDCASE.
      ENDCASE.

What is the difference between Topic Keywords and Index File Keywords?

What is the difference between Topic Keywords and Index File Keywords? Any advantages to using one over the other? Do they appear differently in the generated index?
RH9.0.2.271
I'm using Webhelp

Hi there
When you create a RoboHelp project you end up with many different ancillary files that are used to store different bits of information. Many of these files bear the name you assigned to the project at the time you created it. The index file has the project name and it ends with a .HHK file extension. (HHK meaning HTML Help Keywords)
Generally, unless you change RoboHelp's settings, you add keywords to this file and associate topics to the keywords via the Index pod. At the time you compile a CHM or generate other types of output, the file is consulted and the index is built.
As I said earlier, the default is to add keywords to the Index file until you configure RoboHelp to add the keywords to the topics themselves. Once you change this, any keyword added will become a META tag in the topic code. If your keyword is BOFFO, the META tag would look like this:
<meta name="MS-HKWD" content="BOFFO" />
When the help is compiled or generated, the Index (.HHK) file is consulted as normal, but any topics containing keywords added in this manner are also added to the Index you end up with. From the appearance perspective, the end user woudn't know the difference or be able to tell. Heck, if all you ever did was interact with the Index pod, you, as an author wouldn't know either. Well, other than the fact that the icons appear differently.
Operationally, keywords added to the topics themselves may hold an advantage in that if you were to import these topics into other projects, the Index keywords would already be present.
Hopefully this helps... Rick

What is the difference between Video-out and mirroring?

What is the difference between Video-out and mirroring? I can't get iPhone 4 video to work on my TV screen
I have just bought an MD098ZM/A (Apple 30-pin Digital AV Adapter). I am struggling to get it to show a picture on my TV. I know I'm doing something right because the audio is coming out of my TV speakers but no picture on the TV screen.
I have used the same HDMI channel (on the TV side) with the same cable and my thunderbolt port (MacBook Air) without any trouble - and on the same app (BBC iPlayer download then full-screen mode).
Now I note that the packaging for the MD098ZM/A says video-out on iPhone 4 but mirroring only on iPhone 4S. I only have an iPhone 4 (not the 4S). Now if the lack of iPhone 4 support for mirroring means that I can't play video material out to my TV, then in what sense is there any video-out capability at all?
There is only safety and warranty paperwork in the Apple adapter packaging - no help information. And I haven't found further guidance online either.
I do note somewhere online that it suggests that basic non-mirroring video-out (for this adapter) only works with some external TV sets. Any way of finding out which? I'm using a Sanyo CE32LD90-B LCD TV if it helps.
So far not doing very well.

Now found these but have had to give up on this adapter!
