.openDatabase version management?

Hello

Could someone please explain in more detail how .openDatabase handles the Version parameter? Specifically, what happens if there is a database with the same name but a different number of (old) version? So if I have an existing database with version 1.0 and I call .openDatabase with the parameter Version "2.0", what is happening? It overwrites the current database? Is it creates another database? Does just error? The documentation here doesn't https://bdsc.webapps.blackberry.com/html5/apis/Database.html say.

I would like finally to verify if there is an existing version of the database, and it is current or former of the database version. It seems I should use .openDatabase, but the documentation states that if .openDatabase does not find an existing database, it will be just to create a new. The documentation does not specify if a different version number is an "existing database".

Thank you

It is a very good intro:

  • Device Version Manager: 6.1.7600.16385 presenting no matter what devices or Windows 7 Home Premium 64 Bit drivers? This has already been answered? If you don't see it you can check or update all drivers.

    14/07/13

    Whenever the device driver is selected there is just a blank page that appears. There are no announcements of any drivers anywhere, or visible by any way within Windows 7 Home Premium. For this reason there is no way to check on all the drivers or the parts of the system to see if there is no system conflicts.  I have a driver repair program that when search enabled for and comes with a list of drivers on the computer and indicates the factors that bear on a date and will go through the steps to change but since I have no way to see the driver manager or it's poster so I can't say if something is changed.

    If I have something again plug it into a USB Port, the computer recognizes that something has been plugged, but that it will not open the directory automatically, as it used to do.  For example if I put in a CD or a DVD that has auto start it won't, so it's just sitting there. If I use Windows Explorer and click computer directory will show a device for example: DVD has a DVD named such and so in the drawer.

    Plug-and-Play is selected and activated, but it seems that it does not work.  If I plug a USB key into the USB (any USB port) it sometimes it indicates with a beep or a pop-up window indicating something was plugged or removed as the case may be.

    If this file has been deleted, if it is to cause such a thing?  This computer (gateway) has a grounded partition which has a restore works however it resets all default settings etc. or can erase all files.  If there is a way to download the missing files, which makes Driver Manager do its thing, it would be a good thing. Any suggestions?

    22/07/2013

    Thank you for your suggestions. They were a good start, I followed everything as suggested, but nothing helped.

    1. as to the question was just a new program installed before this problem?  The answer could be Yes. But unknown to you, because I can't be sure of the effective date of what's going on.

    I tried to go back, at an earlier date, but it did not help.

    2. for Plug and Play - he already is set to Auto and is active, but it is grayed out and I can't change it. So it turns out that I'm locked somehow. Even if I am put as an administrator.

    3. I went into the registry and everything what you suggested is already there.

    4. the problem still exists.

    Always looking for HELP

    DwBent

    Hi DwBent,

    I would be grateful if you could answer the following question:

    Were there any software or hardware changes made on the computer before this problem?

    This can cause if the Plug and Play service is disabled (disabled people); I suggest you follow the troubleshooting steps and check if it helps;

    Method 1:

    To resolve this problem, set the startup type for Plug-and-Play on automatic. To do this, follow these steps:

    (a) click Start, click run, type services.msc, and then click OK.

    (b) double click on Plug-and-Play. If you receive a Configuration Manager message, click OK.

    (c) in the Startup Type list, click Automatic, and then click OK.

    (d) Community Services.

    (e) restart the computer.

    Method 2: The other reason, Device Manager may be empty is because there are some security issues with the registry key.

    Warning: Important this section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click on the number below to view the article in the Microsoft Knowledge Base:

    Back up the registry

    http://Windows.Microsoft.com/en-in/Windows7/back-up-the-registry

    (a) go to "Start", click "run", type "regedt32" and press enter.

    (b) expand the "HKEY_LOCAL_MACHINE" window

    (c) scroll down to "SYSTEM\CurrentControlSet\Enum".

    (d) with 'Enum' selected, click on "security", "Permissions" menu

    Note: At this point, you'll probably notice that there are no permissions on this key.

    (e) click on 'Add'.

    (f) add the group "everyone" and the "SYSTEM" user.

    (g) select "everyone" and check the "read" ONLY!

    (h) select 'SYSTEM' and check the 'total control'.

    (i) click on the button "Advanced" at the bottom of the window.

  • APEX apps - CVS, Subversion version management

    Hi all

    As in other projects, we are studying how to add version control to our development with APEX.
    Since SQLDeveloper offers Subversion and CVS clients to control the development and we have access to the schema of the APEX (FLOWS_030000) user, it seems possible, but also tedious.

    Any experience or idea with it?

    Thanks in advance.

    Hello Pau,

    Take a look at my blog on the backup of Apex, available here - applications

    http://Jes.blogs.shellprompt.NET/2006/12/12/backing-up-your-applications/

    I show how you can use the command line APEXExport to export your applications, which can be easily scripted and extended to automatically archive the Subversion etc.

    In addition, Dimitri wrote a post on SQLDeveloper and Subversion integration - here

    http://dgielis.blogspot.com/2008/05/using-Subversion-in-SQL-Developer-easy.html

    In fact, I use automated much export, because it is good to know that you always have copies of your apps snack the "worst" should occur.

    Hope this helps,

    John.

  • Version VS scenario management

    Hello gurus,


    I'm the introduction of ODI (v11.1.1.5) in the business, and we are interested in its capabilities of version control.

    We have seen that the scenarios are useful for work on an interface, while a fixed version of it can still be executed in a package. Thus, we always generate a new version of a script after the change of an object. Our packages consist of scenarios with-1 as the value for the version field (get the latest version of the script).

    This is very useful, but how can we see the implementation of an interface/package to a specific version of the script? I guess it must be stored somewhere, since the old scenarios are still usable after the interface has changed. I have not found where the notice/regenerate the previous version of the object.



    My research led me to this article on Version Management: http://docs.oracle.com/cd/E21764_01/integrate.1111/e12643/versioning.htm
    This concept seems to do what I want: be able to recover the old implementation.
    However, I do not understand why this concept is not related to the notion of scenarios. Do you know what is the reason for having two separate notion 'versioning '?



    Do you know how to take advantage of these two concepts?
    < li > to work a bunch of interface/while our packages can still use the previous release version (which is done using a scenario).
    < li > be able to retrieve the implementation of previous versions (which is done by version control if I am not mistaken).



    Thanks in advance for your help.


    Best regards

    Yes. The Version 001 scenario is a black box. You can't say what interfaces/packages/models, etc. are contained in the code of the script.
    And Yes, its very important to add documentation for scenario as to what this scenario did or what all the things it uses.

  • Two versions of Photos in El Capitan?

    I used a local network file server to store my library iPhoto for years.   I could access it from multiple Macs on the local network, but recently I came across a surprising problem.  I've updated several computers to El Capitan, an old Macbook Pro, a MacPro and a new Macbook Pro.   The old Macbook Pro got installed version 1.3 of Photos, and the other two got pictures version 1.2.   I did not notice this until I accessed the common photo library with the old Macbook Pro - which worked fine, but then, days later, I tried to access the library from the Mac Pro, and he says that the library from a newer version of pictures and that I must upgrade Photos.  But there seems to be no way to upgrade Photos - not from the App Store, and when I even download and re - installed El Capitan, is still version 1.2!   So I can't access the library two computers until there's another OS update that modifies the Photos again?  This seems quite strange and incompatible version management, even if using a base common library LAN is not a common practice.   I don't want to use iCloud for storing my large library and my local network is certainly faster than my Internet connection.

    Any suggestions on how to get Photos 1.3?

    Thank you.

    Photos is installed as part of Mac OS X.  You cannot update separately.

    If you have pictures on one of your Mac 1.3, you have installed a beta version of El Capitan on this system, probably MacOS X 10.11.2.  Upgrade all of the Mac to the same version of Mac OS X, if you want to share the library of Photos between devices.

    I have used other sync software that accesses the calendar notes just to check my notes calendar was not inaccessible for any reason whatsoever and that worked well.

    If it's a version management issues with Notes 8.0.2 is there a way I can go back to the previous version of the portable software that works well so far? Otherwise, any suggestions to solve this problem?

  • Update blackBerry Smartphones / Device Manager issue

    Hey guys, I have a problem.

    I recently acquired a Blackberry 8330 and let me start by saying this: it's one of the best machines I've ever held. It is simply amazing.

    I installed the Device Manager and have been using it without any problem. Then, I went and did an update wireless with my phone, the upgrade of the OS. Since I did this, however, the Manager has recently stopped recognizing my device - my computer recognizes him again, as he charges when it is plugged in and I can always access to the hard drive, but for some reason, I cannot use the Device Manager to do anything - down, States in the Device Manager there is no trendy Black Berry as shown by the 'None' exposed next to the Pin number.

    What can I do? I really need to access blackberry via the Device Manager. Someone, please help > _

    Things I've tried:

    -Restart the Blackberry (both by pressing the red button and pull the battery and re insert)

    -Update the device to the more recent version Manager

    -The latest version is uninstalled, then download and install the version provided with the blackberry (4.2)

    I noticed that the CD that came with the device itself does not contain the most recent edition of the Device Manager, if that means anything. It's just weird that the Device Manager has stopped working after I upgraded. Currently, my OS is V4.5.0.175. I've recently updated both my 8310 Black Berry - same question parents. Before, I could access it via Device Manager. Now, I can't. Please help me!

  • Versioning... need suggestion

    Hello

    I use SVN for version management. But I would like to know if I still using default of ODI for objects versioning.

    Basically I would only export the highest environment scenarios. Any other object, we'll go to QA.

    can you please if there is an impact to versions twice IE a next and odi level is at SVN survey.

    Please suggest

    Thank you

    ASP.

    Hi, ASP,.

    I want to say that Yes, you can optionally use SVN but not as a replacement of versioning ODI and solutions ODI.

    Let me tell you about the key elements of the ODI versioning.

    In ODI, you can have as many types of versioned objects:

    (1) projects

    (2) records

    (3) packages

    (4) interfaces

    (5) procedures of

    (6) sequences of

    7-user functions

    (8) variables

    (9) knowledge modules

    (10) model files

    (11) models

    (12) scenarios of

    NOTES:

    (a) how best and how you have to release all of your work in ODI

    (b) he has not compiled the code itself

    • For example, a package is your code, but the scenario generated from this package is your compiled code (frozen)

    (c) a scenario can be generated from:

    • Packages (mainly)
    • Interfaces
    • Procedures
    • Variables

    (13) load plans

    (14) solutions of

    You can version all ODI objects mentioned above, transparently in ODI.

    • You can browse the
    • You can compare different versions together
    • You can restore any version of the object at any time in the repository of work
    • The version information itself is stored in the main repository

    You asked: "I use SVN for version management. But I would like to know if I still using default of ODI for objects versioning. Basically I would only export the highest environment scenarios. Any other purpose we will go to the QA. »

    (1) you can export scenarios (deployment) is optimal, but you will find it useful and "need of versions of ODI" to compare, for example, two different versions of packages to know at what stage has been added/updated / delete. To achieve the latter you can create a package version, change the package, create another version, use the version of the browser in the menu of the ODI and choose/select versions of both packages and then right click and compare.

    How you would show the difference in action between two different versions of package ODI in SVN?

    (2) nothing can replace the version management of the ODI in regards to ODI

    You asked: "can you please if there is an impact to versions twice IE one ODI and next is level to SVN survey.»

    Well, the ODI version information is kept in the master repository (relational Tables), SVN version information is stored in its own specific repository.
