Migration to OAS

Hello

(If I posted this in the wrong section please move the thread. (Thank you!)

I have a few questions about migrating from oracle forms 6i at least version 10.

Some background information:

At the moment we use oracle 10.2.0.5 (Linux) with forms 6i and its time to upgrade.

Given that the forms 6i are not compatible with the 11 g database (at the very least, it is not recommended to use not supported)

We thought to stick to the current database version and put first in the Forms 10 and later upgrade to

version the most recent database and forms/States.

We are not sure if it's the best approach?

You must understand that we have a lot of application developed in forms/reports 6i (more than 1000) and

migrate all will take time, so we think running forms6i paralel to Forms 10 and

aplication slowly compilation / migration to version 10 of the form. Centerly we cannot go 'offline' with production

for any period of time.

Now, I have a question to which I don't have a straight answer yet.

For us to upgrade to version forms 10 that we need:

(a) application server 10 g - it can be executed on the host windows from our database is on linux, are there problems in the said combination?

(b) developer oracle 10-> This is the only package for developers?

(c) and what else do we need. ... I mean I'm used to client-server env. where each user has access to the client installed on his PC.

(d) anything else?

Our developers are not qualified in PL/SQL this upgrade will be no problem given the Java with OAS support.

will we in the future a Java developer?

If we follow this way is it possible to upgrade to the latest version of forms/report of database 10g...

without mounting/recompilation aplications?

And another thing what concerns us is oracle application server - oracle weblogic.

(a) what is the difference?

(b) how to improve us the weblogic server application server?

We know that we took off the coast of this upgrade for many at since a long time and now we have more problems that we should.

What we want is a stable env. that will be functional, secure and will allow us to develop better applications with less fuss.

Anyone with some previous experience in migration could please let us know of any idea about this, and what would be the best way

to handle this.

Regards, Matt.

I have a few questions about migrating from oracle forms 6i at least version 10.

First of all: do not migrate a version to yet another version desupported desupported. The most recent Version for forms is 11.1.2.1; If you use discoverer, you might want to take a look at 11.1.1.7 which is essentially forms, reports and discoverer grouped in one package.

At the moment we use oracle 10.2.0.5 (Linux) with forms 6i and its time to upgrade.

Given that the forms 6i are not compatible with the 11 g database (at the very least, it is not recommended to use not supported)

We thought to stick to the current database version and put first in the Forms 10 and later upgrade to

version the most recent database and forms/States.

We are not sure if it's the best approach?

You must understand that we have a lot of application developed in forms/reports 6i (more than 1000) and

for any period of time.

You will not have to do the migration on a running system? You will definitely need to make some changes to your code, because the architecture of Web Forms is different from the architecture of the C/S forms, so an upgrade to a newer version that you can expect from an upgrade of database using DBCA (with additional tests) certainly will not happen. When we migrated our forms for

11g I first installed an application of 11g server, copied the files and compiled, made some code changes (we have already been in 10g, so I had to make only minor changes) and tested, tested tested. When I had finished, I built a version 11g and handed over to QM for further testing. Doing things in parallel with the form after form live seems so good to me, after all your users will need access to certain parts of the application through C/S and items migrated via the web. In theory, this may look good as you will not have a big bang, when you switch from the C/S for the web, but as said at least for me it sounds a little confusing.

Also have a look at the forms upgrade Center:

http://www.Oracle.com/technetwork/developer-tools/forms/index-095046.html

Also, google gives you a good impression on the migration of forms; After all many forms developers went if it and are willing to share their experiences freely on blogs and whatever else.

And just to add a tip: If you do not already have a version control system with your forms under version control * before * starting the migration would be a very good idea.

see you soon

  • Migration of application (using the Trinity) 11G ADF Rich Faces

    Hi all

    We have recently completed the migration of the ADF/JSF application of 10G, hosted on OAS to Trinidad hosted on WebLogic Server 11G. Next step is to move from the Trinity to rich faces.

    1. our request is not too complicated, but it's not too straight forward or the other. It is interfaced with Oracle BPEL and DRM (data relationship management) and has 20 + pages. Is there a way to estimate how much time/effort is required for this migration?

    2. automatic migration of 10 g and 11 G (usingTrinidad) was quite chaotic. What kind of effort is migration 11G application using ADF Rich Faces trinidad? What is the meaning of ' you have to manually re-doing the UI "?"

    If any of you have done this kind of migration, please share your experiences.

    Thank you

    One thing to think is maybe rethink your UI. ADF Faces 11 g can create a radically different compared to 10 g interface or Trinity - think of things like accordions, dispatchers, dashboards, tabs, pop-up windows on the plan of the presentation of the user interface and the ability to have much more than information on one page. Add to this the ability to dynamically switch the content of a page with dynamic regions and offered by taskflows reusability.
    So if you really want to take advantage of the components 11g you should look at what UI you wanted to create with these abilities then redraw your user interface and redesign so that it matches this.
    Your model and business services cannot stay the same no need to touch.

    I had a project of BC4J (9.0.3.11.88), made with the Jdev (9) oldy and deployed OAS (9) and I had to migrate/upgrade to the latest version of Jdev (11) and Weblogic (10.3.5).

  • I can't save analyses after you download Sierra OAS

    I can't save analyses after you download Sierra OAS.

    The "Save" button is grayed out?

    Hello 2014anthony1,

    Thank you for using communities of Apple Support.

    I see that you can not save scans after updating to Mac OS Sierra. I would make sure I can save analysis too, I do a lot of scanning on my Mac. Let's work together and get this problem is resolved.

    I suggest to use macOS Sierra: update or change the printer software, more precisely, that these sections:

    Most printers are compatible with Mac OS. When you add a printer, Mac OS automatically uses AirPrint to connect to the printer or the printer software downloads (also called a printer driver).

    If you can not use a printer that is already added, or you see not the options you want in the print dialog box, you can add the printer again with different or software to print settings different.

    Add your printer with different parameters

    1. Choose the Apple menu > System Preferences, and then click Printers and scanners.

    2. Select your printer from the list, and then click the button Delete .

    3. Click on the button Add and if a context menu appears, choose Add a printer or a Scanner.

      A dialog box is displayed that lists all Hello, IP, printers directory shared, and open on your local network. It may take a minute or two for your printer to appear.

    4. Select your printer, when it appears in the list, and then do one of the following:

      • Use AirPrint: Click on the drop down menu, then choose AirPrint (or Secure AirPrint). If AirPrint is not on the shortcut menu, the printer does not support it.

      • Use a printer software installed on your Mac or downloaded from Apple: Click on the drop down menu, then choose Select software.

      • The software to print a file on your Mac: Click on the dropdown menu, then select other. Select the file, and then click Add.

    Update your printing software

    If your printer is not how to use AirPrint, you can use Software Update to download the latest version of the software. If you don't do this, you see a message that software is not available when you connect your printer.

    • Choose the Apple menu > App Store, and then click updates.

      Install the software updates that are listed for your printer.

    • If the software for your printer is not available using the software update, you can contact the manufacturer for more information. Maybe it's that your printer is not compatible with Mac OS. To check, see the article Apple Support printer and scanner software available for download.

    If you install the printing software you don't have Apple, printing software can not be updated automatically when you use the software update.

    Let us know if that helps. We'll help you get through this.

    All the best!

  • Open migration to Active Directory directory Windows vs Mac

    OK, so I help my old school to their IT needs, because they do not have a person hired for this role.

    Currently, they have a center where the staff use computers based on Windows 10 10 (systems of Core 2 Duo, especially assembled; all about 3 years) connected to a Windows 2008 Server (from Dell; about a year). As the institution wishes to expand the computers available to their staff (from 90), my suggestion was to move to Mac (probably 11 '' MBAs), with a MacBook Pro 15 "is the duty of the server.

    This migration can be done in one shot and would happen progressively (probably MBAs purchased each year for the next four years, 20-25).

    The current configuration is that there is a local + Admin user configured on each of the 10 Windows PC - based, with all personnel having access to the user not local administrator.

    In order to facilitate the management, I would like to move to the logons on the network, as we begin our migration to a Mac OS environment.

    Should we configure AD on Windows Server and bind it as MBAs, and when to buy us, with the final being the MBP 15 "for server-buying functions, or is it possible we can get the MBP 15" now and use Open Directory and binding the existing 10 10 Windows-PC with the macOS Server?

    NOTE: The school operates Google Apps, and all employees have a Google Apps account with a custom domain name.

    You can't link PCs to Open Directory without using 3rd - Party (page). In addition, depending on the operating system will not work reliable? You'd have to trial it first. Beyond bond and provide a home folder there will be nothing else. No management, no policies etc Open Directory to your PC.

    Support way to achieve this is to use Active Directory and complete with OD to manage your estate of mac only. Again, you can apply GPOS for Mac without 3rd - Party help which can be very expensive.

    Not that it's something that you would consider - although you could do? It may be preferable to go ' all the mac "If your intention is to switch to Mac OS. If your PC using the software that is available only for PCs consider using virtual machines on your Mac to keep this aspect of the school.

  • migrate Photos pictures of the camera

    My brother-in-law (senior senior!) is struggling to migrate images from his camera for Photos.  He has just upgraded its imac 2009 at El Capitan 10.6.8 10.11.6 so this is a big step.  He has done the conversion from iPhoto in pictures, but when he plug his camera, the content opened in pictures, but when he clicks on import, nothing happens.  It is about 3,000 km, so I'm the middleman.  I use the same software and have no problem, so I fight for help.

  • Migration process now broken

    Hello

    I'm migrating a server running 10.8.5 to a new Mac running 10.11.6. It was very well - I took a Time Machine backup, it has migrated to the new Mac, download server, ran Monday, and everything has worked just like that.

    Thursday, since server was updated to 5.2, after migration and download server and running it, he refuses now to update saying I need to run an earlier version of the server or OS X to do the migration. I have no way to get the version that was available for download on Monday but, not that I can see.

    Any advice?

    Solved by Apple support - buy a Mac running 10.11 prior to version 10.11.6 and the App store will download an older version of the server. That can be copied in all and the migration done with this version.

  • Mail of the Mac Mini, iMac with the migration wizard

    I have a mac mini (2014 - El Capitan) that I have used for some time now and I have many mailboxes (30 +) with many stored messages (100s maybe 1000s).

    I recently picked up a 2011 27 iMac which is running OS X Sierra Final Release Candidate due to vision problems.

    Both units are working well but I would like to transfer my boxes to the letters, messages, and the account settings from the Mac Mini to the iMac using Migration Assistant to take advantage of the larger screen.

    Am I able to select only the data for e-mail (boxes letters, messages and settings) to transfer somewhere in the Migration Wizard interface or will it just to start the transfer of all?

    I use iCloud for note, calendars and contacts, but prefer not to use for e-mail.

    Any help would be greatly appreciated.

    Thank you

    The simplest option would be to use Time Machine to restore your data.

    Other Options:

    You can export the folders you want to transfer the mini using export of Mail under mailbox function in the Menu bar > export a mailbox... Drag to the folder on the desktop on the new iMac and import in Mail. File > import boxes mailbox...

    You can also use a third-party application, Emailchemy to export your Mail on the mini and pull only the folders you want and import. If you have many files, it would be a faster option.

    http://www.weirdkid.com/products/emailchemy/

    Otherwise, you could drag on the whole Mail > V3 folder let Sierra update data. This assumes that you have already started using Mail to Sierra.

    You don't have to use iCloud email to use Apple Mail. I strongly suggest that you use IMAP to service what ever you choose to use.  Comcast, Yahoo, Gmail, AOL, Hotmail (other)

  • Understand migrations from iPhoto to Photos

    After you migrate an iPhoto for photo library, the file extension of the iPhoto Library is changed in .migratedphotolibrary, and my understanding is that the two libraries share the same files through the use of "hard links". I've also read that if one of the libraries is published subsequently, what causes the link between versions of break. Is this true?

    If so, my questions are:

    (1) If hard links break, this means that storage on hard drive required by the two libraries is increased by the size of one of the libraries? If so, who would not take a little time if the booksellers were important, for example 100 GB or more?

    (2) immediately after the migration, what happens if one of the libraries I move to a different folder? Again break hard links? If so, same question as above.

    No - change or deletion of a form of photos a library does not break the hard link and has no effect on the other library - they are totally independent

    1 - Yes

    2. Yes, I believe that to break hard links - travel for sure as a library to another volume break

    Why move a? Usually simply leave you it where it is for several months until you are sure that you need is no longer and then archive and delete

  • Migrating to SATA drive to iMac

    Four days ago my MacPro (2010) died. I have four 3 "SATA drives from 1 to 2 to each of Mac Pro. The computer was for business and personal use. Absolutely everything (including financial information) I have is on these four discs, including redundant copies of some files, but also my Time Machine backup.

    I will have an envelope coming tomorrow which is a RAID box but will be executed in the independent drive with four drives Mode. My 'new' computer is an iMac (2013), that was given to me.  The iMac and the main SATA drive running the same version of the operating system. I need to resolve this issue quickly so I can return to work. In the immediate future, I intend to operate out of the primary SATA drive to catch up, and then transfer when I'll have a good time to transfer.

    My question is the best way to get the entire contents of the primary SATA drive on the iMac's hard drive. I want everything that is on the main SATA drive to put to be on the iMac (including the prefs and hidden folders) of Mac Pro and it would be the same when I booted the Mac Pro.

    Can I use migration utility, clone the drive SATA main to the iMac or even use the Time Machine backup?

    If I clone the drive, I know that I would have to boot from one disk other than the iMac drive to clone to the iMac. When the primary SATA drive is attached, I need to boot from it by holding down the option key at startup key to select the startup disk.

    If I use the Migration utility, it seems I start the iMac, and then run the utility to the iMac of the SATA drive range, which would be connected to the iMac. This would replace all the information on the iMac even though it was the boot drive?

    I printed the information on the Migration of Apple Mac help when transferring to another storage device, but it's not quite clear to me.

    Messages and e-mail accounts and data are found in/Home/Library/Messages/and/Home/Library/Mail/files. Just copy the content to the same folders on the new computer.

    Or you can migrate your complete folder from the old computer to the new home. This can be done using the love at first sight between the two cable and on the new computer using target disk Mode use the Migration Wizard to migrate your application. It could also be run from a time Machine or another external backup drive.

    Migration will not overwrite any user account that has already been created on the new computer. MY simply creates a new Admin user account name. You will then need to switch to the newly migrated account.
