when i try to us my email account on itunes or on my iphone it says please review what does this mean and how can i sort it
BEfore you try to Restore it, try a simple Reset.
Press and hold both the Sleep/Wake button and the Home button for at least ten seconds, until the Apple logo appears (ignore the Slide to Power Off option that shows up first). -
Can anyone direct me to a good overview of the new features of iOS 6 (I use an iPhone 4S) so I know what I've got and how to use it? Thanks!

What is SQL Trace and How to Use it .
Dear Experts .
1.) May You Please tell me What is the Purpose of SQL-Trace and How to use it ?
2.) What is purpose of T-codes SE30 and ST22 ?
Please it is urgent ...
Regards : RajneeshHi
SQL Trace transaction ST05: The trace list has many lines that are not related to the SELECT statement in the ABAP program. This is because the execution of any ABAP program requires additional administrative SQL calls. To restrict the list output, use the filter introducing the trace list.
The trace list contains different SQL statements simultaneously related to the one SELECT statement in the ABAP program. This is because the R/3 Database Interface - a sophisticated component of the R/3 Application Server - maps every Open SQL statement to one or a series of physical database calls and brings it to execution. This mapping, crucial to R/3s performance, depends on the particular call and database system. For example, the SELECT-ENDSELECT loop on a particular database table of the ABAP program would be mapped to a sequence PREPARE-OPEN-FETCH of physical calls in an Oracle environment.
The WHERE clause in the trace list's SQL statement is different from the WHERE clause in the ABAP statement. This is because in an R/3 system, a client is a self-contained unit with separate master records and its own set of table data (in commercial, organizational, and technical terms). With ABAP, every Open SQL statement automatically executes within the correct client environment. For this reason, a condition with the actual client code is added to every WHERE clause if a client field is a component of the searched table.
To see a statement's execution plan, just position the cursor on the PREPARE statement and choose Explain SQL. A detailed explanation of the execution plan depends on the database system in use.
Run time analysis transaction SE30 :This transaction gives all the analysis of an ABAP program with respect to the database and the non-database processing.
STEPS
Run time analysis transaction SE30
In Transaction SE30, fill in the transaction name or the program name which needs to be analyzed for performance tuning.
For our case, let this be ZABAP_PERF_TUNING
After giving the required inputs to the program, execute it. After the final output list has been displayed, PRESS the BACK button.
On the original SE30 screen, now click on ANALYZE button.
The percentage across each of the areas ABAP/ Database/System shows the percentage of total time used for those areas and load on these areas while running the program . The lesser the database load faster the program runs.
SQL Trace ST05
Starting the Trace:
To analyze a trace file, do the following:
Choose the menu path Test Performance Trace in the ABAP Workbench or go to Transaction ST05. The initial screen of the test tool appears. In the lower part of the screen, the status of the Performance Trace is displayed. This provides you with information as to whether any of the Performance Traces are switched on and the users for which they are enabled. It also tells you which user has switched the trace on.
Using the selection buttons provided, set which trace functions you wish to have switched on (SWL trace, enqueue trace, RFC trace, table buffer trace).
If you want to switch on the trace under your user name, choose Trace on. If you want to pass on values for one or several filter criteria, choose Trace with Filter.
Typical filter criteria are: the name of the user, transaction name, process name, and program name.
Now run the program to be analyzed.
Stopping the Trace:
To deactivate the trace:
Choose Test Performance Trace in the ABAP Workbench. The initial screen of the test tool appears. It contains a status line displaying the traces that are active, the users for whom they are active, and the user who activated them.
Select the trace functions that you want to switch off.
Choose Deactivate Trace. If you started the trace yourself, you can now switch it off immediately. If the performance trace was started by a different user, a confirmation prompt appears before deactivation-
Analyzing a Sample trace data: PREPARE: Prepares the OPEN statement for use and determines the access method.
OPEN: Opens the cursor and specifies the selection result by filling the selection fields with concrete values.
FETCH: Moves the cursor through the dataset created by the OPEN operation. The array size displayed beside the fetch data means that the system can transfer a maximum package size of 392 records at one time into the buffered area. -
What's accessorIterator? And how to use it?
JDeveloper 11g, ADF BC
Hi,
I noticed in the executables bindings the "accessorIterator" binding type, and when you browse the DataControl to choose one you can see the viewCriterias and their nested elements. How is this useful? What are the cases where you can use accessorIterator?
For example if a view attribute is a LOV that has a bind variable, is there a way to use the accessorIterator to set the bind variable's value? and how? or the accessorIterator is not ment to be used for such cases?
Thank you in advance for your reply.Repost.

What chair stand for and how to use it ?
I cannot find any explanation about "chair" and "group" in lightning, when to use them, and what difference there is between chair and required or optional attendee.
Moreover if I send an appointment to a list, do I have to use chair and individual or optional attendee and group ?
Thanks"Chair" means the owner or chairman (political correctness requires we say "chair" because "chairman" is apparently sexist, and "chairperson" annoys some people) of the meeting. There doesn't need to be one, I think; I can't ever recall using "chair" when issuing invitations. If it's ''your ''meeting then maybe you are the "chair". ;-)
"Group" probably means a Mailing List; a pre-built and ready-to use list of email contacts. I use these for project members at work, and for family at home. You can create these Mailing Lists in your Address Book.
In a business meeting, there may be particular experts or specialists who need to be there for the meeting to have any useful outcome, so they are "required". There may be others for whom it would be useful to attend the meeting but their absence wouldn't prevent the meeting being successful. They are "optional".
All rather a lot of overkill for informal appointments between friends or family. ;-) -
What is adaptive RFC and How to Use it
hi friends
what is the adaptive RFC
what is the use of it
how we can use it
explain me anyone
and send pdf also
thanks
ramu.Hi,
To give u a brief idea.
rfcs are used to call data from the backend that is R/3.We use the Bapis from the R/3 system which have some pre defined functionality and data is populated in the correspoding ui elements in webdynpro interface.earlier Rfcs were used but now we have adaptive rfcs in which
if there are changes in the backend(R/3 system) such as changes in the datatype,structures,fields would be automatically be refllected in the rfcs and there would be no errors in web dyn pro even if there is a change in the back end
to be more specific folow this link
http://help.sap.com/saphelp_nw70/helpdata/EN/41/38bc8f813719488ddc9d9b21251ec3/frameset.htm
and try out this application
to use the rfcs firstly check out this document for configurations

What's Http Channel and how to use it?
Hello, there:
I heard if people use Swing applets as front end GUI instead of JSP, they need to use sth called Http Channel for the communication b/w applet and servlet, I don't know too much about it neither I could too much info from the net.
Anyone can tell me about it? Some examples are better,
appreciating your help!
SwayI don't know much about Http Channel (never heard of it before), but normally people use HttpURLConnection.

What are the advanteges and disadvanteges of using pl/sql over hibernate
i knwo that pl/sql are well structure and provide a lot of functionalities with oracle databse , but my question is the hibernate might give some advnateges of scalability over pl/sql.
so what are the advanteges and disadvanteges of using pl/sql over hibernate?
and does oracle recommend using hibernate for connecting JSP with oracle 11i , or it is better to connect the JSP pages with oracle databse using pl/sql ?812643 wrote:
but if i search for the diferencess then there are a lot of opinions about this ..., specially when they say that with hibernate you can integrate with any DB , and it provides object printed architecture, etc.All databases are not equal. This is a basic and fundamental fact. SQL-Server is not Oracle. Oracle is not SQL-Server. As it is the case with Sybase, Ingres, DB2 and other database products. They are all different. And there are some very core differences between them.
So how would a product like Hibernate treat these database products with their differences? By using the lowest common denominator. Which means your expensive database product is dumbed down - and even MS Access will likely have better and more features.
You also need to decide what is the "permanent" part in your architecture. What is going to the core? What is the expensive part? The app server (with Hibernate)? Or the database server?
What are you likely to change next year? The app server server? Or the database server?
In the vast majority of cases, the core is the database server. That is your biggest expense and investment. As it should be - as it holds that which is most precious to business, data. You want to ensure the integrity of that data. The accuracy of that data. Make sure that it can be easily backed up and recovered. Is flexible to use. Etc. Etc.
The database server is the core - and that is where you need to realise your return on investment. By using the database server to its full extent.
Hibernate does not do that. And in that respect, it is junk.
Why does it not do that? Because many Java developers are totally and fully clueless about what database servers are and how to use them. And want to use them as little plug-in black boxes - bit buckets that are only there to provide a data persistence layer. Instead of using the database server to its full extent, they instead use Hibernate, and try to do their own "+database thing+" in the app layer - and do it poorly and with utter lack of any scalability. (and no, only ignorant Java heads think that scalability means throwing more money and h/w at it)
My largest database processes billions of rows per day, every day, 356 days a year (between 350 to 450 million new inserts into a single table per day). And have been for several years now. It does so using PL/SQL. Using Oracle to its full extent. Then there are Java heads that cannot even design and code an app that effectively process 1% of this volume... and grasp at straws like Hibernate and other Java cr@p to "fix" this - when the actual problem is their total lack of ignorance in how to use and scale the database server.
Hibernate is trash - and a symptom of Java developers's ignorance of database technology. -
I get this error message quite frequently:: (TypeError: attempt to run compile-and-go script on a cleared scope) what does it mean and how do I stop it? It doesn't happen always but it is often.
Ever since the 6.0.2 update - every single day there's been something new going horribly wrong. For the past couples weeks it has been the browser hanging or crashing for no apparent reason and now this error hitting the browser screen over and over a hundred times a minute. I've used firefox since it began and NEVER had any issues previously. This 6.0 upgrade is a downgrade and is making me seriously look at Chrome (never IE - why I switched to firefox), though making the switch will be a pain due to all the apps I rely on and thousands of bookmarks that would need to be transported. Please mozilla fix this because using this browser has suddenly gone from seamless to frustrating pretty much overnight!

I had water damage to my iphone5 when I was deployed w/ the military overseas. How can I find out what saved to icloud and how to see where my photos are. I don't know when it was able to back up as wi fi was pretty sketchy. please advise. thx in advance
My iphone is toast, I know I checked on icloud and see my emails from the day before it happened. Can I see when and what my phone backed up through itunes or icloud?
Please please help i am lost.This was EXACTLY what I needed about the purchases I made from my device. However, is there a way to re-download other ones you've made from a computer? Because I realized some of them were not just purchased from my device.
This is a picture of what it looks like now:

As you can see, the stuff circled in red doesn't give me an option to download from Cloud Beta because it already says "downloaded".
any way to get around that? -
Hello I forgot my Security question of my Apple ID ? I don't kow what should I do and how to solve this problem ? could you please help ?
You need to ask Apple to reset your security questions; ways of contacting them include phoning AppleCare and asking for the Account Security team, clicking here and picking a method for your country, and filling out and submitting this form.
They wouldn't be security questions if they could be bypassed without Apple verifying your identity.
