How to replicate applications

Scenario: Two database servers with one schema to replicate from one server to the other (one-way replication).
On both servers we have APEX set up. We can copy the applications (export/import), but we would prefer to have a replication-like scenario, where changes to the application on the main DB are replicated to the copy DB.
How to set this up?

Well all the APEX applications are defined in objects owned by the APEX_030200 schema (or similar if you have a version other then 3.2).
If you could replicate these schemas drom one database to the other this would achieve what you want. I'm not much of a DBA though so I'm not sure how you would achieve that (other than with export/import).
You would still need to bear in mind though any changes you make to DB objects owned by other schemas etc.

  • [Forum FAQ] How to deploy applications remotely

    In some situations, we may need some ways to install applications remotely, here we summarize four general ways to deploy applications.
    1. Using PowerShell to install
    We can use the Win32_Product class to install Windows Installer packages, remotely or locally, so in this way, we can use powerShell command to invoke this function. For example, to install the NewPackage.msi package located in the network
    share \\AppServ\remote on the remote computer PC01, type the following command at the Windows PowerShell prompt:
    (Get-WMIObject -ComputerName PC01 -List | Where-Object -FilterScript {$_.Name -eq "Win32_Product"}).Install(\\AppSrv\remote\NewPackage.msi)
    In same method, we can use the following command to deploy .exe application:
    (Get-WMIObject -ComputerName PC01 -List | Where-Object -FilterScript {$_.Name -eq "Win32_Process"}).Create(\\AppSrv\remote\NewPackage.exe)
    Note: The applications should use Windows Installer technology.
    2. PsExec tool: one of sysinternals utilities
    PsExec's most powerful uses include launching interactive command-prompts on remote systems and remote-enabling tools like IpConfig that otherwise do not have the ability to show information about remote systems. So, we can use this feature to install our
    applications, in fact this is similar with PowerShell methods, the only difference is that PsExec is a comprehensive tool. Similarly, we can use the following command to achieve our goal:
    psexec \\PC01  cmd /c  "\\AppSrv\remote\NewPackage.msi" /quiet /norestart
    Note: we can also use PsExec tool to install Microsoft Update file (.msu)
    psexec \\PC01  -s -h -d wusa.exe  "\\AppSrv\remote\NewPackage.msu" /quiet /norestart
    3. Group Policy Software Installation
    In domain environment, this method is very useful to deploy our software. It only supports MSI package for deployment.
    We can choose assign a program to user or computer. If you assign the program to a user, it is installed when the user logs on to the computer. When the user first runs the program, the installation is completed. If you assign the program to a computer,
    it is installed when the computer starts, and it is available to all users who log on to the computer. When a user first runs the program, the installation is completed.
    You can get the installation information of group policy software installation in event viewer, including success or failure.
    4. System Center Configuration Manger
    The Microsoft System Center Configuration Manager software distribution feature provides a set of tools and resources that help you create and manage packages and advertisements used to distribute software to client resources within your enterprise. This
    is a comprehensive suit for deployment.
    How to Deploy Applications in Configuration Manager

    Summary:

    Here is another important point of software deployment: Some applications do not use windows installer technology. 
    Applications that do not use Windows Installer technology may have application-specific methods for automated deployment. For example, a .exe file may be just a wrapper, it can be anything. To determine whether there is a method for deployment automation,
    check the documentation for the application or consult the application vendor's support system. In some cases, even if the application vendor did not specifically design the application for installation automation, the installer software manufacturer may have
    some techniques for automation.

  • How to use application managed entity manager in EJB?

    I finish reading The EntityManager Interface in JEE tutorial.
    I know I can use container manager entity manager in EJB, but I want to explore how to use application managed entity manager in EJB.
    Can I use application managed entity manager in EJB (container management JTA transaction is used)? Where do I should close entity manager if can?
    The following is an example from JEE tutorial, but didn't find where to calose entity manager. and can I create mutiple EntityManagerFactory objects and Entity Manager objects to use them in a JTA transaction?
    @PersistenceUnit
    EntityManagerFactory emf;
    EntityManager em;
    @Resource
    UserTransaction utx;
    em = emf.createEntityManager();
    try {
      utx.begin();
      em.persist(SomeEntity);
      em.merge(AnotherEntity);
      em.remove(ThirdEntity);
      utx.commit();
    } catch (Exception e) {
      utx.rollback();

    Seems like a very poor example, the whole power of EJBs is to use Container Managed Transactions so you don't NEED to manage the transaction and the entity manager yourself. What you posted is code I would expect in a non-JEE application, or in a piece of code which requires fine-tuned transaction boundaries such as batched data importing logic.
    If I were you I'd research JPA in steps.
    a) learn about JPA as an API outside of the scope of EJBs (recommended reading: the book 'Pro JPA 2')
    b) learn about Container Managed Transactions in EJBs
    c) learn about Bean Managed Transactions in EJBs
    Right now you're rushing into c). I can understand that it raises many question marks at this point.

  • How does Facebook application utilize Blackberry push based architecture?

    Hi Friends,
    I have posted this message in Blackberry Java Development forum. But was told that "if you are not RIM you will not be able to use the push-architecture with BIS". 
    Here goes the actual message. Please provide your valuable inputs.
    I am developing an Blackberry client application which will be similar to Facebook application for Blackberry.
    Since, this application can be  download by any blackberry user who would be subscribed to different BES or BIS, how will the push based architecture of BB work here.
    See my previous post 'Push content to devices on different BES' (http://supportforums.blackberry.com/rim/board/message?board.id=java_dev&message.id=3196&jump=true#M3196), which says that push will work through BES.
    If that is the case,
    How does the FaceBook application for Blackberry work?
    Users who download the Fackebook application will definetly not be on the same BES or might be on BIS as well.
    Then how will Facebook application receive notificatios and messages instantly using blackberry's push architecture?
    (http://www.blackberry.com/news/press/2007/pr-24_10_2007-01.shtml)
    Does RIM provide any framework or support for developing facebook like applications which would utilize push architecture irrespective of BES or BIS?
    Thanks,
    Suresh.

    Facebook doesn't use the BlackBerry network, it uses the standard data network.  If you're on BES, that typically is routed through your BES server.  If you're not on a BES, it will use BIS.
    I don't believe the application is a "push" application either - it's more likely a real time IM client.

  • How to delete application deployed in Run Application Only mode?

    I have exported/imported an application (Run Application Only mode) from one DB instance to another.
    As a developer, I cannot see the application in Application Builder in the target instance. This is as intended because changes should only be made on the source (development) instance.
    After testing, there may be errors to correct. The application is not going to be a new version, it is going to be corrected on the source instance. Without creating a new version of the application on the source instance, what steps does the HTML DB admin take on the target instance to delete the application so the application can be imported again?
    Thanks,
    Kelly

    Thank you Scott. I missed the help text to the side of the install page that explained how an existing application is deleted and replaced.
    The tool provided the prompt page, Confirm Replace Application, before proceeding with the install.

    Hi,
    Can someone please help me on how to replicate data from MS SQL Server to Oracle 8i database.

    Dear,
    I'm a student.
    I do simple replication on Oracle 8.0.5 successfully. (one master site and one snapshot site). I only use the SQL*Plus and Schema Manager to do.
    But when I do advance replication (multimaster replication) I meet many problem. So I don't get the result.
    Do you show me the technology to do that ?
    Thanks !

  • E-Rec : How to assign applications to requisitions?

    Hello Experts,
    We have just started blue-printing of E-Rec and I am successful creating a requisition from Recruiter's page. I am just concerned how to assign applications to a requisition as search doesnt work being a very new system. I was trying to create an application using link "Create External Applications" from Recruiter's login page. Please guide.
    Additional details: We have ECC and E-Rec on different box with EhP5.
    Thanks and regards,
    SAP E-Rec Guy

    You can always search for postings using a reference code - TREX and the indexes do not need to be setup for that to work.  The create internal / external applications link is really used for a recruiter to create an application on behalf of a candidate.  You could always just register a new external candidate and search for the job posting using the reference code and apply that way.

  • How to create Application Workspace with Jdeveloper 10g 1.3.2?

    Following the instructions in "Developing and Using ADF Faces Skins", I am trying to create an Application Workspace.
    The instruction says: "In JDeveloper, create a new Application workspace and name it - ADFFaces_skin_sample"
    I can not find the way to create Application workspace with Jdeveloper 10g 1.3.2.
    Because when I click FILE==>New I got "New Gallery--Application" in left, in right only got "Application, Empty project, File, Java Class, Java Interface". There is no "workspace" item.
    I try to use Jdeveloper 10g 1.3.1, got same result.
    I found other ADF Skin training samples. All of them asked to create Application Workspace. But the Jdeveloper version used by all those samples were earlier than 10g 10.1.3.2
    Please let know how to create "Application Workspace"?

    What used to be "Application Workspace" in 10.1.2 is "Application" in 10.1.3.2
