What development tool should I change for ?

Hello everyone,
English is not my native language, please excuse my errors.
I am currently working at the engineering department of a huge chemical company, and I have been given the responsibility to choose what development tool would suit best for the software developers of the department.
I am not an expert at all and I need help.
The developers used to use Forms 6i, but they are planning to change because they want to update all their Oracle tools. The problem is: should they use Forms 11, Jdeveloper, APEX or something else? I have made some research on these tools but I can’t find a comparison of them.
Up to now, the development team has made softwares with Reports and Forms 6, which were running on Windows XP PCs, connected to an Oracle 8 database on a server. Tired of taking care of installation and administration on every PC, they have decided to make softwares running on server, to be used by many people at the same time through the company’s network.
My question is: is there a better tool to realise these web based softwares?
What are the advantages and drawbacks of the different development tools?
The team is going to “migrate” old softwares as well to make them run on a server, I have tried the APEX 3 migration tool, and Forms 10 migration tool, but I get to nothing good, I am probably doing it wrong… but is there an easy way to migrate from Forms 6i to another tool?
I really hope that I made myself understood.
If not, just ask me what you did not understand and I will try to explain better.
Please, help me out :)

First is to decide with management what is their objective
then check your budget :)
joke aside.
moving to ADF is the best solution but migration requires a major rewriting same with APEX so it is depends on where your expertise are
APEX is good for small application like 10-20 tables but for enterprise level application you should go for Oracle ADF and Oracle SOA Suite which would help you to improve business processes and control on application and once you migrated you are free for 10 years at-least :)
Bottom line:
- if you have more PL/SQL resources migrate to Forms 11g and train your team to Java and Oracle ADF
- If you have more Java resources then start re-writing from scratch to ADF.
Migrating to forms 11g is better choice which will keep your platform same so in future you have flexibility to move to ADF without any platform change.
i have prepared few presentations about ADF and Migration to ADF from Forms might help you http://baigsorcl.blogspot.com/2010/05/my-adf-presentations.html

    What antivirus protection should I purchase for my MacBook Pro? MacSecurity.app appeared on my desktop, and I downloaded that. Since then, it has said my computer is infected and pop-ups have been appearing.

    You've been infected by a scam trojan.  You don't need any anti-virus software on your Mac.  See the following about getting rid of the trojan.
    Trojan War
    If you discover a trojan program is running on your computer then look to the following information for assistance:
    1. A recent discussion on the Apple Support Communities: MacDefender Trojan.
    2. An excellent site devoted to Mac Malware: Macintosh Virus Guide
    3. Another site for removing MacDefende, et.al.: MAC Defender Rogue Anti-Virus analysis and Removal
    4. A new removal utility - MacDefenderKiller
    Removing strange software can be a task.  The following outlines various ways of uninstalling software:
    Uninstalling Software: The Basics
    Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash.  Applications may create preference files that are stored in the /Home/Library/Preferences/ folder.  Although they do nothing once you delete the associated application, they do take up some disk space.  If you want you can look for them in the above location and delete them, too.
    Some applications may install an uninstaller program that can be used to remove the application.  In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
    Some applications may install components in the /Home/Library/Applications Support/ folder.  You can also check there to see if the application has created a folder.  You can also delete the folder that's in the Applications Support folder.  Again, they don't do anything but take up disk space once the application is trashed.
    Some applications may install a Startup item or a Log In item.  Startup items are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder.  Log In Items are set in the Accounts preferences.  Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab.  Locate the item in the list for the application you want to remove and click on the Delete [-] button to delete it from the list.
    Some software use startup daemons or agents that are a new feature of the OS.  Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
    If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term.  Unfortunately Spotlight will not look in certain folders by default.  You can modify Spotlight's behavior or use a third-party search utility, Easy Find, instead.  Download Easy Find at VersionTracker or MacUpdate.
    Some applications install a receipt in the /Library/Receipts/ folder.  Usually with the same name as the program or the developer.  The item generally has a ".pkg" extension.  Be sure you also delete this item as some programs use it to determine if it's already installed.
    There are many utilities that can uninstall applications.  Note that you must have this software installed before you install software you may need to uninstall.  Uninstallers won't work if you install them after the fact.  Here is a selection:
    AppZapper
    Automaton
    Hazel
    CleanApp
    Yank
    SuperPop
    Uninstaller
    Spring Cleaning
    Look for them and others at VersionTracker or MacUpdate.
    For more information visit The XLab FAQs and read the FAQs on removing software and dealing with spyware and malware.
    After removing all the components of the software you may have to restart the computer to fully disable the software.  This will be the case when removing software that has installed a daemon.  After the daemon has been removed you need to restart the computer to stop the daemon.  Alternatively, you can kill the daemon process using the Terminal application or Activity Monitor.

    Hello
    I want to install windows vista instead of the XP i have by default in my laptop Satellite A100 PSAA8.
    * which version should i go with; *64-bit or 32-bit* ?
    * and what about x86 and x64!?
    * will I find all drivers in the download section for the new OS?
    * will there be any non-working component or function after installing ?
    The new OS will make me do extra efforts every time re-install, I wish I can have any thing similar to the recovery CD of my laptob (+with the one click install with drivers also+) but has windows vista, :-(
    Is there any solution to make it easier any time i re-install?
    _Thank you in advance ._

    According Toshiba download page your notebook is supported for Vista 32-bit. There you can find all drivers, tools and utilities designed for Vista.
    There is also installations Instructions document. Use it for right installations order.
    So what you must do is to obtain Microsoft Vista installations DVD.

  • What One Specification Should I Look for When Buying Optical 5.1 Speakers for the iMac 27" i7?

    Hi. I have an analog 5.1 (it came from my previous PC setup) now but only the subwoofer works, the controller for its satellite speakers maybe have been busted by the high voltage from the outlet (I've since gotten a nice AVR). If replace it since the late 2009 iMac and Macs in general only do surround sound (5.1 or higher) if it's not analog. I've read somewhere that is should be digital or optical.
    When I look for the specification that'll make this Mac do 5.1 surround, what should I look for in the speaker's specifications. I believe the non-analog 5.1 speakers are way more expensive, I'll probably buy one used but what brand and model can anyone recommend that's not that expensive, iMac/Mac compatible and will be easy to setup (you just plug it in into it's the headphone jack at the back) that'll do 5.1 on Lion and Snow Leopard (I have both installed for backup OSes and experiments). Thank you in advance.

  • What virus protection should i download for my macbook pro

    i just got my macbook pro and want to know what virus protection program should i download for free

    This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an attacker who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
    All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files. The recognition database is automatically updated once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders. In most cases, there’s no benefit from any other automated protection against malware.
    Starting with OS X 10.7.5, there is another layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications that are downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Applications certified in this way haven't actually been tested by Apple (unless they come from the Mac App Store), but you can be sure that they haven't been modified by anyone other than the developer, and his identity is known, so he could be held responsible if he knowingly released malware. For most practical purposes, applications recognized by Gatekeeper as signed can be considered safe. Note, however, that there are some caveats concerning Gatekeeper:
    It doesn't apply to software that comes packaged as an installer. Treat all third-party installers with caution.
    It can be disabled or overridden by the user.
    It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets (see below.)
    It only applies to applications downloaded from the network. Software installed from a CD or other media is not checked.
    For more information about Gatekeeper, see this Apple Support article.
    Notwithstanding the above, the most effective defense against malware attacks is your own intelligence. All known malware on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. If you're smarter than the malware attacker thinks you are, you won't be duped. That means, primarily, that you never install software from an untrustworthy source. How do you know a source is untrustworthy?
    Any website that prompts you to install a “codec,” “plug-in,” or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
    A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. [Some reputable websites did legitimately warn users who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.]
    “Cracked” copies of commercial software downloaded from a bittorrent are likely to be infected.
    Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. No intermediary is acceptable.
    Java on the network (not to be confused with JavaScript, to which it's not related) is always a potential weak spot in the security of any operating system. If Java is not installed, don't install it unless you really need it. If it is installed, you should disable it (not JavaScript) in your web browsers. Few websites have Java content nowadays, so you won’t be missing much. This setting is mandatory in OS X 10.5.8 or earlier, because Java in those obsolete versions has known security flaws that make it unsafe to use on the Internet. The flaws will never be fixed. Regardless of version, experience has shown that Java can never be fully trusted, even if no vulnerabilities are publicly known at the moment.
    Follow these guidelines, and you’ll be as safe from malware as you can reasonably be.
    Never install any commercial "anti-virus" products for the Mac, as they all do more harm than good. If you need to be able to detect Windows malware in your files, use the free software ClamXav — nothing else.

  • What video settings should I select for 60m of video in iMovie

    My gear: HDTV, DVD player that upconverts to 1080i, Canon HG10 HD camcorder
    I record in HD. I have both an HDTV and a 4:3 standard TV. I don't have a Bluray player, nor do I want to invest in one at the moment.
    I only need to record 60 minutes of video at a time to a single DVD.
    Question: what settings in iMovie should I use to ensure the BEST video quality when I play back on my HDTV and DVD player that upconverts?

    If you shoot 30p, ingesting 960x540 should be enough for your DVD output. If you use 60i, then importing and outputting at 1080i would be important to maintain 60Hz motion smoothness. (You shouldn't use stabilization or cropping while editing to avoid damaging 60i.) Then use MPEG streamclip or JES deinterlacer to resize 1080i 60 to 480i 60 to feed DVD authoring tool.
    Or, you may want to use iMovie09 only as an importing tool for AVCHD video. Use imported movie (1080i AIC) in iMovieHD to edit movie and send it to iDVD, which will preserve 60i motion.

  • What development tools are available to a student to add functionality

    Hello,
    I am a student who wants to add some functionalities to the SAP Strategy Management software,

  • What sequence setting should I use for a High Quality Video Montage?

    I am about to start a new project for a client using photographs only.  I have two questions:
    1.  What should I use for the sequence settings?  Should I edit with a HD sequence setting? 
    2.  I am going to scan the pics myself.  What Pixel or resolution is appropriate to get the best quality?  I'm looking for wide screen 16 x 9, not 3 x 4.

    First, decde how you are going to deliver this production to your client. Then tell us what that delivery medium will be. Then we'll have some advice for you.
    See the section in the FCP manual on using still images. You need to understand that in video there are only pixels, no dots per inch or lines per inch. Those terms are meaningless in video. You wil sand at a size in raw pixels that is only slightly larger than your delivery format.

  • What volt charger should I get for my MacBook? It is a DC to AC inverter?

    Hi, I recently purchased a inverter charger that has an outlet to charge a computer and can be used as a typical USB charger for a phone. The charger says that it has a continuous charge of 120V but a maximum of 150V. I don't understand what the problem is though because on the MacBook charger it says that it's intake is 100-240V and all of the other outputs and inputs match the specifications for the charging device. A normal phone charger that you can plug into the wall worked in this charger, so is it the computer or the charger? And also if it is the computer, what voltage amount should I get? Thank you very much!

    Your Macbook charger will specify the number of watts it uses (very fine print somewhere on the charger brick).  Your inverter MUST be able provide at least that much power, or I'm guessing your Macbook charger would have problems.

  • What Screen Resolution should I Design For?

    Hi,
    For APEX applications in public sites, what should be the proper screen resolution should I design for? Also, when I put something like a chart in a region, the size of the chart is always fixed. Therefore, it may not fit a particular screen size. I am wondering what should be the proper screen resolution I should target for - considering different desktop monitors and tablets?
    Thanks.

    Hi,
    sky123 wrote:

    Also, when I put something like a chart in a region, the size of the chart is always fixed. Therefore, it may not fit a particular screen size. I think it is OK to have some elements with a fixed size, like charts and images, while the rest of the page resizes itself. Charts are a problem because I don't think you can give them a "width=100%" as you can do with images. I think it depends on your audience. If only 5% of users will see the page in a small screen, you should use a big chart, and vice-versa. Or have two charts, one big and one small, and dynamically hide/show them based on the screen size?
    If you use Apex 4.2, it has very interesting themes. For instance, I was surprised to see how fluid this page I created was:
    http://apex.oracle.com/pls/apex/f?p=65861:3:0::NO::P3_ROWID:AAjQ4rAGlAAAADUAAB
    If you make the browser window narrow enough, the order items region will move underneath the customer orders region... Cool! :)
    (using CTRL+ to make the page bigger doesn't do the trick though...)

  • What Credit Cards Should I Apply For?

    Hi there, My Ch7 was discharged 4/15/15. I have applied for a First Premier Card (approved at $700) & Target (declined) and that is it. What cards should I apply for? Trying to rebuild and not sure how to go about it. Any advice is very much appreciated. All accounts are showing as closed on credit reports except for student loans.  Transunion is 558/ Equifax is 575

    Hello, My BK7 was discharged in late March. I just applied for Express and New York & Co store cards using this link http://www.doctorofcredit.com/shopping-cart-trick-get-credit-cards-without-the-hard-pull/ This link contains a list of retail cards you can get with a SOFT PULL!! Just go to the retail site, put items in your cart, go to checkout.  If a card invitation pops up, click on it and be sure to use the same address that's on your credit report. The application only asks for the last 4 of your SS.  Since I recently moved, I entered my old address and immediately after approval called customer service to update my address and find out the credit limit.  Each account has a $250 limit. I think this  is a good way to avoid secured cards or worse yet, cards like 1st Premier and Credit One with outrageous rates.  My cards will arrive any day now! With proper usage of these accounts and my student loans reporting good payment history, I expect to receive unsecured offers in a few months.
