How ADF BC can cope with unexpected changes to the underlying database

Hi all,
i have been experimenting with Fusion Web Applications based on ADF BCs for a few weeks now. The framework is, indeed, very powerful but i wonder if it is flexible too and, in particular, if it is able to smoothly adapt to changes occurring on the underlying database. I have some doubts about that cause, in some circumstances, i found myself in the need of modifying the database structure (removing or adding columns or constraints to tables) and, though i was able to quickly and easily reflect those changes to entity and view objects thanks to ADF synchronization, the consequent adaptation of the existing JSPXs based on the previous definition of the view objects was quite painful: i found very hard to reflect the changes to the JSPXs and, in some cases, i had to rewrite the pages from scratch!
Since the company i work for is projecting to use ADF for realizing a web application backed by a very large database (which i bet will undergo to numerous changes during the development phase!) i'd like to know if there is something i'm missing here and to ask you some advices on the recommended approaches to develop agile and flexible Fusion Web Applications with ADF BCs.
Thanks in advance, bye!

You will need to be more specific about the issues that you have encountered. Synchronization and refactoring is supported in JDeveloper for the model, the view and the controller. For what it's worth, take a look at these entry-level posts that could provide some additional inside:

How many computers can sync with Apple TV at the same time?

I'm thinking of buying one of these things for my parents as a last-minute Christmas gift. They both have their own iMac, with their own choice of music/movies/photos/etc. If I get them this device and set it up in their living room, could they stream content from both computers to this?

When you say "online" you mean bonjour, right?
So all I'd have to do for set up, is turn on the "share library" in their iTunes? Alright, sounds easy enough.
No, AppleTV's are set up in a specific manner.
You can sync with 1 iTunes library, and stream from several.
Synced material is seen under My Music, My Movies categories of the respective media types (Music/Movies/TV Shows/Podcasts), and if iTunes is running any compatible material that hasn't synced (copied to AppleTV in order to play if computer is off) can be streamed as needed.
Streaming libraries that don't sync are selected under a My Shared Music/Movies etc category,and stream as needed, but only one is selected at a time.
To set up a library to sync/stream, AppleTV announces itself across the network to itunes, and a 5 digit code appears on the connected TV which is then entered in iTunes on the machine which is being added to 'computers'. Quite simple really.

How do u link copa with ps

Can any body tell me pls how do u link copa with ps
Pls send links or meterial
and how did upload balance sheet in sap

Hi,
For the balance sheet, you could use either LSMW or FB01 (fast entry), if the qunatity of the lines is not huge. For the link; what do you mean exactly? You can define WBS is characteristic in CO-PA if you want and define the proper derivation rule (KEDR).

is this a windows in bootcamp question ?

I have my FireFox browser set to delete the history when I close the window. It was working for a while and has recently just stopped with no changes to the settings.

I have my FireFox browser set to delete all the history when I close the window. It was working for a very long time and has recently stopped with no changes to the settings. This has happened once before and I deleted FireFox and re-downloaded it, that solved the problem for a short period of time but the issue has come up again. How can I fix this?

Can you check your configuration again? Maybe something went pear-shaped somewhere. It's located in Tools | Options | Privacy and then click the Settings button (see screenshot).

How many times can you clean install leopard on the same computer?

How many times can you clean install leopard on the same computer? Will the leopard dvd run out of installations and not let you install anymore?

Hi colman Prez;
Now that the funny comments have been made, I have a serious question and that why are you worry about reinstalling Leopard with an Erase & Install which is what I take that you mean when you say clean install. In actually fact there is no such thing in OS X as a clean install.
I am curious because in all the years I have used OS X, I have yet to do an Erase & Install yet.
I know with Windows that they suggest reformatting and reinstalling at the drop of a hat but that isn't true with OS X.

How do i share music with 2 iphones using the same apple id?

how do i share music with 2 iphones using the same apple id?

Sync them both to the same iTunes music library. You can also automatically download purchased music to both by going to Settings>iTunes & App Stores and turning Music to On under Automatic Downloads. If you music is in multiple computers, you can enable Home sharing to share your music library across multiple devices (see http://support.apple.com/kb/HT3819).

The installer found unexpected changes to the install script

Hi,
I've just try to install PC Client 15.7 "EBF 23439: 15.7 SP130" Just downloded from Service Market Place on a Win 03 R2 32 bit and on Windows 12 R2 64 bit
On Win 03 R3 32 bit it works fine but in Win 12 R2 there isen0t any way to run Sybase Central.
When I try to uninstall, on each machine, there are only thi message:
Unable to lunch installer
The installer found unexpected changes to the install script:

Hi,
So you are saying that PC-Client 15.7 SP130 doesn't uninstall? I will look into this.
If you go to your control panel and installed software.
What version(s) of Microsoft Studio do you have installed?
What versions of Microsoft Visual C++ #### Redistributable Packages do you have?
From what I saw they had pulled the Sybase Central out of PC-Client.
You might be able to get from ASE 15.5 version of PC-Client.
Please note that PC-Client with Sybase Central was never certified with Windows 8 or 2012. So you never get Sybase Central to work on those operating systems.
PC-Client 15.5 last drop should have been certified with Windows 7.
Thanks,
Dawn Kim

I'm not sure I understand the question, is the message tone going more then once?
Turn off repeat message alert here:
settings > notifications > messages > repeat alert > never
Some people have found this does not stop the repeat miessage tone,
if you are one of those then I suggest you contact Apple:

They may not respond, but hopefully will fix in uodate if enough people complain.
