Knowledge n skills required to run Application Express

Hi Gurus,
Can anyone plz inform regarding the knowledge and skills that are required to create, run and maintain any application built using Application Express
i.e the skills required for an Administrator, Developer and any other that I forgot.
Thanks
Any help is appreciated.

It depends on what you plan on using it for, but for the basics:
<BR><BR>
Start by reading the 2 day developer that should make sense with a simple understanding of HTML, Javascript and SQL. Even without any knowledge or experience a bit of experimenting will have you using the tool relatively quickly.
<BR><BR>
The best thing is just to download XE and set it up as testing/learning APEX and see what you need to take it from there to where you want to go. Once you are experimenting and have more specific questions the forums should be more than enough to get going.

Unfortunately I can't provide much help, other than that we have seen this before with 9iR2, but haven't yet figured out when this does occur, so not sure if it's related to a specific patch version. If possible, I'd recommend upgrading to database 10g or higher. And if we do figure out under what circumstances this problem comes up in 9iR2, I'll post this on the forum.

Application Express 3.0.1 Upgrade

I am running Application Express 2.0.2.00.49 and the backend is Oracle 10.2.0.1.0
on Linux 32bit and 64bit 9.3 Susie Servers. I want to upgrade to the new 3.0.1 Application Express and wonder what steps or tricks there might be waiting for me when I do this.
Thanks,
Tim

Tim,
Hopefully, there shouldn't be any tricks whatsoever. It should be as simple as a normal installation of Application Express, and your existing data (e.g., workspaces, applications) will be migrated forward.
Like with any type of upgrade, if you have the opportunity, it's prudent to take a backup beforehand.

Application Express 2.2 on Windows x64 Edition?

Hi,
I am running Application Express 2.2 on a server running Windows Server 2003 Standard x64 Edition with Service Pack 1. I am running Oracle Enterprise Edition 10g R2, and I also have Oracle Application Server 10.1.3 installed.
Whenever I log into our application express applications, the server slows down majorly. I have to end the process for the explorer window and restart the htmldb service for it to go back to normal again. In my alert.log file, I see errors such as the ones below that occur at the same time that I try to login to an htmldb app. Is ApEx 2.2 for 32-bit only? Could this be causing problems, or could it be something else? Any suggestions or thoughts would be appreciated.

Hi Nora,
Application Express 2.2 is supported on Windows Server 2003 Standard x64. There really is nothing magical about Application Express - it's all SQL and PL/SQL, so it runs without problems across any platform that runs PL/SQL (unless it's EBCDIC, but that's another story).
This looks like an underlying database issue. I found evidence of a couple issues filed by customers with the same symptoms - and they weren't using Application Express at all. This further supports my assertion that it's a database issue on your platform and not an issue with Application Express, per se.
Unfortunately, all I can recommend at this point is that you contact Oracle Support and/or file a TAR. They are in a better position to assist.
I hope this helps.

I am trying to install itunes after downloading Windows 8.1. I get an Windows Error 2 message-- "Apple Application Support is required to run itunes helper." Any suggestions?

I am trying to install itunes (64 bit) after downloading Windows 8.1 on my HP Laptop. I keep getting an error message Windows Error 2--"Apple App;ication Support is required to run itunes helper" Does anyone have any simple suggestions for a user with limited knowledge of Computers?

With the Error 2, let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR suitable for your PC (there's a 32-bit Windows version and a 64-bit Windows version):
http://www.rarlab.com/download.htm
Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
Does it install properly for you? If so, see if iTunes will launch without the error now.
If instead you get an error message during the install, let us know what it says. (Precise text, please.)

Apple Application Support was not found. Apple Application Support is required to run iTunesHelper. Please uninstall iTunes and then install iTunes again. Error 2. After this I

So when I plugged in my iPhone 4 (iOS 7.0.4), iTunes told me it needed to update to the newest version... so I did. After installing it it gave me an error (-45019) that said that a required component wasn't installed. I looked it up and people were saying to unistall iTunes and all apple related software and reinstall itunes which i did. I am on Windows 8.1.
Now it gives me this error. "Apple Application Support was not found. Apple Application Support is required to run iTunes. Please unistall iTunes and install iTunes again. Error 2 (Windows Error 2)." I did this and it gave me the same message... Please help! How do i get iTunes running again?

I have instlled and uninstalled iTunes on multiple occasions but iTunes fails to start with message "Apple Application support is required to run iTunes .......... Error 2 (Windows error 2)". Most most frustrating. Can anyone help, pleeeeeeease!!

iTunes "Apple Application Support is required... Error 2" and possible fix.
Hi Redgilly (and others).
I just resolved this on Win Vista (should apply equally for Win7 too). Please uninstall iTunes before proceeding though. I'll walk you through the process I followed, if you like you can jump straight to the Solution section.
Problems:
The initial error during the installation of iTunes was:
An error occurred during the installation of assembly 'Microsoft.VC80.CRT,version="8.0.50727.4053",type="win32",publicKeyToken='1fc8b 3b9a1e18e3b",processorarchitecture="x86". Please refer to Help and Support for more information. HRESULT:0x8007054F
The error (after installing iTunes) when trying to run iTunes was:
Apple Application Support is required to run iTunes. Please uninstall iTunes, then install iTunes again. Error 2 (Windows error 2).
After trying various fixes around the forums I came across this MSKB article, which relates to the first installation error:
http://support.microsoft.com/kb/2688946
This lead me to trying to install MS Visual C++ but I received the following error trying to install that:
Error 1935.An error occurred during the installation of assembly ‘Microsoft.VC80.ATL,type=”win32”,version=”8.0.50727.762”,publicKeyToken=”1fc8b3 b9a1e18e3b”,processorArchitecture=”amd64”’. Please refer to Help and Support for more information. HRESULT: 0x80070BC9. Assembly interface: IassemblyCacheItem, function: Commit, component: {837BF1EB-D770-94EB-A01F-C8B3B9A1E18E}
Note: The installation of VC++ rolls back when it fails.
Solution:
Through this error I found this MSKB article:
http://support.microsoft.com/kb/946414
The Automated MS "Fix It" msi package didn’t work.
Note: Please backup your registry first (see the above MSKB article for instructions).
I opened the registry and (as instructed in the MSKB article) deleted the following keys:
HKEY_LOCAL_MACHINE\COMPONENTS\
PendingXmlIdentifier
NextQueueEntryIndex
AdvancedInstallersNeedResolving
Reboot and reinstall iTunes.
I hope this helps.

You have missing information in your Windows programming.
You need to repair your computer so it can run iTunes. If you plug those error codes into your browser you may get an answer.

I took the time to research it and come across a couple of people who experienced the same trouble and so I listed some of there steps(with Credits) and some people said that they worked.
Here is the original Link:
https://discussions.apple.com/thread/2151777?start=0&tstart=0
OK, this worked for me:( Original Post by r0tt3n4pp13)
1. Save iTunes install file to your desktop.
2. Disconnect from internet.
3. Disable Firewall/Security software.
4. Run install. Note that it installs Application Support and a bunch of other software this time.
5. Run iTunes.
6. Enable Firewall/Security software.
7. Reconnect to internet.
8. Download Watchmen Director's Cut post haste.
OR!
(Original post by Cr4z33)
1. Download and install WinRAR.
2. Right-click the iTunesSetup.exe icon and choose "Open with WinRAR".
3. Once the EXE is opened in WinRAR, double-click AppleApplicationSupport.msi and when the installer window is open choose "Repair".
4. Done! You can now run iTunes normally.

Hi texasslagle,
It sounds like you are having issues installing iTunes on your Windows 7 PC, a frustrating situation I am sure.
There is an article that you may want to use to try to complete your install here -

Thanks for using Apple Support Communities.
