What is " factory reset"? How/Why to use it?

What is the "factory rest" feature? How and when should I use it?

The factory reset basically clears all personal data and customizations from the phones internal memory, returning the phone back to the state you recieved it in. This can be used if you get your phone so bogged down that it won't function properly, and as a last resort to fix some major issue that you may be having (though it seems as though VZW tech support usually wants to suggest this first). Your contacts and apps should be saved to your gmail address, and usually get restored automatically when you sign in (and some settings are even backed up now) on first start-up, but you will lose any progress in any games you may have installed, and most apps will have to be set up again.

What are Struts and how it is used in SAP

Hi
can anyone give a idea that what are struts and how it is used in SAP
Regards
JM

Hi John,
In this case google.com really us your friend - Struts is not an SAP technology, rather it is an MVC development paradigm (love using that word for Java. There are lots of useful websites with generic information around struts as well as a number of good books available from Amazon for instance.
As far as Struts and SAP goes - SAP use Struts for their Internet Sales CRM Webshop application. Of course, like anything else from SAP it has been modified slightly but is essentially the same.

What is package,and how can i use it ?thanks !

what is package,and how can i use it ?
thanks

A package is just a way of organizing your code. You organize the code in directories. For example if you have a package called "package database.util" you should put the Java code in a directory called "database/util/".

You have a Puerto Rico address on your account ? From a quick search I've found one site from somebody in Puerto Rico that includes a screenshot for an app receipt showing tax of 7 cents added to a 99 cent purchase. Are you able to view the purchase history on the account that you've been using, and see what prices show on them (e.g. if the store's listed price or price plus tax) : Store > View Account menu option on a computer's iTunes, then 'see all' link next to the Purchase History section.

Row Identifiers
Each row in an Oracle database has a unique row identifier, or rowid, which is used internally by the Oracle database to access the row. A rowid is an 18-digit number that is represented as a base-64 number, and it contains the physical address of a row in an Oracle database. You can view the rowid value for rows in a table by specifying the ROWID column in the select list of a query. The query in the following example retrieves the ROWID and customer_id columns from the customers table:
SELECT ROWID, customer_id
FROM customers;
Oracle instance:
An Oracle instance is the combination of the background processes and
memory structures. The instance must be started to access the data in the database. Every
time an instance is started, a System Global Area (SGA) is allocated and Oracle
background processes are started. Background processes perform functions on behalf of
the invoking process. They consolidate functions that would otherwise be handled by
multiple Oracle programs running for each user. The background processes perform
input/output (I/O) and monitor other Oracle processes to provide increased parallelism
for better performance and reliability.

What are functional modules? why we use them?

HI all,
Please explain what are the functional modules? why we use them? I am talking in reference to SAP HR.
Thanks,
Rashmi

Hi SAP Gurus,
as now i got some idea that SAP has provided lot of funtional modules and also we can create our own function modules,
1, can any one tell with an example when and at what cases this funtional modules are made use of, and how will we come to know which funtional module has to be made use of and for which specific purposes.
2, do you mean to say SAP has provided many funtional modules but they are in Dormant stage untill activated or made use of.
3. Is developing funtional module mainly ABAPers work or could be done by Funtional person alltogether (in case of using the existing FMs
4, When and how this FMs work, what is the trigger point do we have to run this when required, if so how
5, what is the difference Between FMs and UserExits
Can anyone throw some light on this with an example,
Points for sure for Suitable answers
Thanks and Regards

What is LUW? How do we use it in SAP ABAP coding?

Hi Friends,
Kindly explain me what is LUW with examples and how do we use it in our ABAP coding with scenarios why and when we use it?
Regards,
Pradeep

Hi,
SAP LUW
Die Verbuchungsverwaltung
The Open SQL statements INSERT, UPDATE, MODIFY, and DELETE allow you to program database changes that extend over several dialog steps. Even if you have not explicitly programmed a database commit, the implicit database commit that occurs after a screen has been processed concludes the database LUW. The following diagram shows the individual database LUWs in a typical screen sequence:
Under this procedure, you cannot roll back the database changes from previous dialog steps. It is therefore only suitable for programs in which there is no logical relationship between the individual dialog steps.
However, the database changes in individual dialog steps normally depend on those in other dialog steps, and must therefore all be executed or rolled back together. These dependent database changes form logical units, and can be grouped into a single database LUW using the bundling techniques listed below.
A logical unit consisting of dialog steps, whose changes are written to the database in a single database LUW is called an SAP LUW. Unlike a database LUW, an SAP LUW can span several dialog steps, and be executed using a series of different work processes. If an SAP LUW contains database changes, you should either write all of them or none at all to the database. To ensure that this happens, you must include a database commit when your transaction has ended successfully, and a database rollback in case the program detects an error. However, since database changes from a database LUW cannot be reversed in a subsequent database LUW, you must make all of the database changes for the SAP LUW in a single database LUW. To maintain data integrity, you must bundle all of you database changes in the final database LUW of the SAP LUW. The following diagram illustrates this principle:
Database Logical Unit of Work (LUW)
From the point of view of database programming, a database LUW is an inseparable sequence of database operations that ends with a database commit. The database LUW is either fully executed by the database system or not at all. Once a database LUW has been successfully executed, the database will be in a consistent state. If an error occurs within a database LUW, all of the database changes since the beginning of the database LUW are reversed. This leaves the database in the state it was in before the transaction started.
The database changes that occur within a database LUW are not actually written to the database until after the database commit. Until this happens, you can use a database rollback to reverse the changes. In the R/3 System, database commits and rollbacks can be triggered either implicitly or using explicit commands.
Implicit Database Commits in the R/3 System
A work process can only execute a single database LUW. The consequence of this is that a work process must always end a database LUW when it finishes its work for a user or an external call. Work processes trigger an implicit database commit in the following situations:
When a dialog step is completed
Control changes from the work process back to the SAP GUI.
When a function module is called in another work process (RFC).
Control passes to the other work process.
When the called function module (RFC) in the other work process ends.
Control returns to the calling work process.
When a WAIT statement interrupts the work process.
Control passes to another work process.
Error dialogs (information, warning, or error messages) in dialog steps.
Control passes from the work process to the SAP GUI.
Explicit Database Commits in the R/3 System
There are two ways to trigger an explicit database commit in your application programs:
Call the function module DB_COMMIT
The sole task of this function module is to start a database commit.
Use the ABAP statement COMMIT WORK
This statement starts a database commit, but also performs other tasks (refer to the keyword documentation for COMMIT WORK).
Implicit Database Rollbacks in the R/3 System
The following cases lead to an implicit database rollback:
Runtime error in an application program
This occurs whenever an application program has to terminate because of an unforeseen situation (for example, trying to divide by zero).
Termination message
Termination messages are generated using the ABAP statement MESSAGE with the message type A or X. In certain cases (updates), they are also generated with message types I, W, and E. These messages end the current application program.
Explicit Database Rollbacks in the R/3 System
You can trigger a database rollback explicitly using the ABAP statement ROLLBACK WORK. This statement starts a database rollback, but also performs other tasks (refer to the keyword documentation for COMMIT WORK).
From the above, we can draw up the following list of points at which database LUWs begin and end.
A Database LUW Begins
Each time a dialog step starts (when the dialog step is sent to the work process).
Whenever the previous database LUW ends in a database commit.
Whenever the previous database LUW ends in a database rollback.
A Database LUW Ends
Each time a database commit occurs. This writes all of the changes to the database.
Each time a database rollback occurs. This reverses all of the changes made during the LUW.
Database LUWs and Database Locks
As well as the database changes made within it, a database LUW also consists of database locks. The database system uses locks to ensure that two or more users cannot change the same data simultaneously, since this could lead to inconsistent data being written to the database. A database lock can only be active for the duration of a database LUW. They are automatically released when the database LUW ends. In order to program SAP LUWs, we need a lock mechanism within the R/3 System that allows us to create locks with a longer lifetime (refer to The R/3 Locking Concept).
The bundling technique for database changes within an SAP LUW ensures that you can still reverse them. It also means that you can distribute a transaction across more than one work process, and even across more than one R/3 System. The possibilities for bundling database changes within an SAP LUW are listed below:
The simplest form of bundling would be to process a whole application within a single dialog step. Here, the system checks the users input and updates the database without a database commit occurring within the dialog step itself. Of course, this is not suitable for complex business processes. Instead, the R/3 Basis system contains the following bundling techniques.
Bundling using Function Modules for Updates
If you call a function module using the CALL FUNCTION... IN UPDATE TASK statement, the function module is flagged for execution using a special update work process. This means that you can write the Open SQL statements for the database changes in the function module instead of in your program, and call the function module at the point in the program where you would otherwise have included the statements. When you call a function module using the IN UPDATE TASK addition, it and its interface parameters are stored as a log entry in a special database table called VBLOG.
The function module is executed using an update work process when the program reaches the COMMIT WORK statement. After the COMMIT WORK statement, the dialog work process is free to receive further user input. The dialog part of the transaction finishes with the COMMIT WORK statement. The update part of the SAP LUW then begins, and this is the responsibility of the update work process. The SAP LUW is complete once the update process has committed or rolled back all of the database changes.
For further information about how to create function modules for use in update, refer to Creating Function Modules for Database Updates
During the update, errors only occur in exceptional cases, since the system checks for all logical errors, such as incorrect entries, in the dialog phase of the SAP LUW. If a logical error occurs, the program can terminate the update using the ROLLBACK WORK statement. Then, the function modules are not called, and the log entry is deleted from table VBLOG. Errors during the update itself are usually technical, for example, memory shortage. If a technical error occurs, the update work process triggers a database rollback, and places the log entry back into VBLOG. It then sends a mail to the user whose dialog originally generated the VBLOG entry with details of the termination. These errors must be corrected by the system administrator. After this, the returned VBLOG entries can be processed again.
For further information about update administration, see Update Administration
This technique of bundling database changes in the last database LUW of the SAP LUW allows you to update the database asynchronously, reducing the response times in the dialog work process. You can, for example, decouple the update entirely from the dialog work process and use a central update work process on a remote database server.
Bundling Using Subroutines
The statement PERFORM ON COMMIT calls a subroutine in the dialog work process. However, it is not executed until the system reaches the next COMMIT WORK statement. Here, as well, the ABAP statement COMMIT WORK defines the end of the SAP LUW, since all statements in a subroutine called with PERFORM ON COMMIT that make database changes are executed in the database LUW of the corresponding dialog step.
The advantage of this bundling technique against CALL FUNCTION... IN UPDATE TASK is better performance, since the update data does not have to be written into an extra table. The disadvantage, however, is that you cannot pass parameters in a PERFORM... ON COMMIT statement. Data is passed using global variables and ABAP memory. There is a considerable danger of data inconsistency when you use this method to pass data.
Bundling Using Function Modules in Other R/3 Systems
Function modules that you call using CALL FUNCTION... IN BACKGROUND TASK DESTINATION... are registered for background execution in another R/3 System when the program reaches the next COMMIT WORK statement (using Remote Function Call). After the COMMIT WORK, the dialog process does not wait for these function modules to be executed (asynchronous update). All of the function modules that you register in this way are executed together in a single database LUW. These updates are useful, for example, when you need to maintain identical data in more than one database.
For further details, refer to the keyword documentation.
For more details of RFC processing, refer to the Remote Communications section of the Basis Services documentation.

Contact names disappeared only numbers - factory reset, how????

This AM my 4S decided my contact names were worthless and decided I should refer to my contacts by their phone numbers whether it be via text messaging or calling. I have tried restarting the phone and reseting the phone. I'm at a loss, how do I preform a factory reset???
Or does someone have a solution to my cunundrom???

Hi
I have the same problems as Anne Kathrine - just I don't use MobileMe for sync.
Some of my contacts just shows their number in sms, but when I get the message and if they call me, their name shows up as expected. I can also write a sms to one of the persons using their name.
Have also tried the same things as Anne Kathrine has done.

What is eprint and how can I use it?

i just discovered e print on my wireless printer and hooked it all up. What is the purpose of having e print and how do I use it as an e mail tool? Can you give me some examples?

Hello, and Welcome to the HP Support Community!
When you register your ePrint-capable printer with hpconnected.com, and your printer is alive on a home network, you can now print to it from anywhere in the world via email!
Any file added to an email as an attachment , and sent to the printer's email address will be spit out of the printer! This works for phones, computers, tablets, etc.
You can print a simple email itself by forwarding the email to your printer's email address. I set up a Contact in all my HP devices named "Printer", and I give it the email address HP provided me when I registered the printer. Anything I want to print is done by forwarding to "Printer"!
Using an Android device, or iOS device can be enhanced by downloading the HP ePrint app. It will add additional wireless printing capability to the devices.

2015 Yosemite 10.10.2 MacBook Pro factory reset how can i do??

Help Help How can i factory reset my 2015 Yosemite 10.10.2 MacBook Pro??

Boot with command-R held down to the recovery partition. Then when it comes up, select utilities and then Disk Utility. In Disk Utility, erase your hard drive, and then install OS X, and you'll be back to "factory reset" condition.
Note you'll lose all data so you should have a backup of anything you want to keep on external media.

Messages on my MacBook Pro is not working after factory reset, how can I enable it?

I just recently (yesterday) got my MacBook Pro Mid-2012 restored after having a few issues with it. So it is totally "clean."
Today I tried to open Messages which worked previously, but it wouldn't let me send a message to anyone (who I could message before the restore) and if I was able to send a message it would show an "Message Can't Be Sent" symbol next to it. I went to Messages > Preferences > Accounts > and saw that my account was enabled but my email used is in a grey font and it will not let me add my iPhone number.
I have signed in and out, deactivated and reactivated the account and I still cannot message anybody.
Please help guide me into fixing this, I have looked at other boards and it doesn't really help me with my predicament. How can I send a message?
Also in the Messages menu, "My Status" is grey and I can't click anything and as well with the "Log In" option. If this can help developing an idea of what might be wrong.

It won't send it to other emails, but it will for phone numbers. Not sure why, but if you can help with sending to other iMessage emails I would appriciate it :-)

Qosmio X500-04N - Factory reset, how long it takes?

I have chosen to reset my X500 04N back to factory settings and the system did it's har Drive thing then openned windows for "Preparing for first time use" but has then been 'Configuring System" (Toshiba window) and rebooting for almost 2 hours now. I haven't even got to the point of entering my own details yet.
How long is this process supposed to take?
Cheers
David

David I know it sounds crazy but 2 hours is Ok. I have installed recovery image on my Satellite P500 several times and can confirm that I waited more than 2 hours for whole image installation.
There is no reason for panic. Recovery image contains so many drivers and Toshiba tools and utilities so I think there are more than 60 different components that must be installed.
By the way: can you imagine how long is needed when you want to install all these components alone? I think 3 hours or longer.

What are mapping services and why they use so much cellular data?

I previously had an iphone 5 and my monthly cellular data consumption was about 250MB.
I recently switched to an iphone 5S and the cellular data usage is about 250MB per week!
I try to monitor and reduce the usage but the mapping services in system services is always very high!
What is this? Can I reduce it?

Mapping Services ( story ) :
In April 2011, iPhone and iPad users were surprised to discover that, not only was their device keeping track of where they’d been, it also was storing very detailed location information in a plain-text file on the phone. The data was derived by the cell towers and Wi-Fi hotspots the devices encountered, and was added anonymously to a crowdsourced database.
Apple later said the devices were keeping more information than intended due to a bug, and issued a patch that reduced the amount of data. But, because it was used to improve and speed up location services, the practice continued.
And now, in iOS 7, Apple has added a tool that lets you see what your iPhone knows about where you go.
If you’ve got an iPhone 4S or later running iOS 7, follow these steps:
1. Go to Settings, then Privacy > Location Services.
2. Scroll to the bottom of the list of apps that use Location Services (and feel free to marvel at how many apps do!). Tap System Services.
3. Tap on Frequent Locations, then scroll down and look at History. You’ll see at least one city there, more if you travel.
4. Tap a city. You’ll see a list of locations you’ve visited in the city.
5. Tap a location. You’ll see a list of the dates and times you visited that location.
Why in the world would Apple collect this kind of detail about your movements? It does so to enable features like Next Destination, found in the Notification Center, which is the screen you see when you swipe down from the top of the iOS display. Next Destination looks at your travel patterns and offers information about how long it will take to get to the next place you typically visit during the day.
If having all this location data collected by your iPhone makes you nervous, you can turn it off at Settings > Privacy > Location Services > System Services > Frequent Locations. Note that it is turned on by default, so if you don’t want your phone logging your whereabouts, you’ll need to turn it off.
The Next Destination feature is similar to one found in Google Now, which uses location and your habits to offer up useful information without your asking for it. Google Now is found in the Google Search app on both Android and iOS. On Android, you can add a Google Now widget to your home screen to make the feature more accessible.
In fact, Google collects similar information about you – and in greater detail - if you use its location-based products. Google stores your location data on the Internet, and you can see it on any Web browser.
Make sure you’re logged into your Google account – say, through Gmail – and then go to google.com/locationhistory. You’ll see a map showing location visits for today, but click the Dashboard link at the top of the page and you’ll see this:
To turn this off, click the gear icon in the upper right corner of the Location History page and choose History Settings. Then, click Disable and Save. There’s also a History Management link that lets you delete history items that have already been collected.
Location services are really an integral part of a ton of iOS apps, using the internal GPS system to add Instagram photos to a map, checkin with FourSquare or Facebook, or let your friends know where you are with one of many “on my way” apps, like Glympse or Twist.
If you’re battery is dying, however, the location services are the first thing you should turn off, as they suck up a lot of your iPhone, iPad, or iPod touch’s power needs, what with their background data sending and receiving and such.
Here’s how to turn them off.
Tap your Settings app to launch it, and then tap on Privacy. You’ll be able to turn the toggles OFF for any specific app that has privileges to access your GPS location by scrolling through the list and tapping them all. I do this on a fairly regular basis for both privacy and battery savings. I figure that with less apps accessing my location, the less battery power in total is being used for that function.
If you want to turn off Location Services completely, then simply tap the main toggle at the top to OFF, and you’ll stop using them. This will keep your apps that need it, like Maps or Compass, from knowing where you are, but the battery will thank you.
Follow the above steps to turn off Location Services :
