What is Apps DBA and  Core DBA?

Dear Friends,
I often come across the terms 'Apps DBA'. I have been trying to get it clarified from many, but I am not convinced. I want to know what is the role of Apps DBA?
What are the duties performed by Apps DBA? How is it different from core DBA?
I request you to explain on the above subject.
Thanks and regards
Bharath Kumar V

Hi Bharath,
I want to know what is the role of Apps DBA?That's a common question! An Oracle Applications DBA is very different from a regular Oracle database administrator and requires specialized skills in business administration and Oracle application server architectures. The Oracle Applications DBA job role is less compartmentalized than a traditional Oracle DBA and the Oracle Applications DBA must also have skills in these areas:
- Database Design - Many shops require customized functional extensions and reporting data marts and the Oracle Applications DBA must have outstanding Database design skills.
- Oracle Application Server - The Oracle Applications DBA must understand the internals of the Oracle concurrent manager and understand how to monitor and tune Oracle Applications.
- Functional Expertise - Many shops requires a business degree and a general understanding of the Oracle Applications module. For example, accountants are widely used to support Oracle eBusiness Suite (Oracle Financials), and accountants with an IT background are easily trained in Oracle Applications DBA support.
I have my full notes here, on theb Apps DBA job roles:

  • Browser and what's app

    hi i have a blackberry 9300..
    i wipped my phone and retarted it and i started to have problems with my browser everytime i go on it i don't get options. i get a message saying Uncaught exception: shared webkit instance unavailable: null. 
    i have tried everything, like sending servive book and to register now and restarted my phone but it has been no help.
    Also my what's app chat history doesn't save yet i have deleted the im what's app folder and it worked for two three days and after that it has stopped.
    can someone help me please 

    I recommend a clean OS reload:
    1. First locate your carrier and the OS file you wish to use.
    http://na.blackberry.com/eng/support/downloads/download_sites.jsp
    2. It doesn't hurt to do a manual backup of your device first, using Desktop Manager > Backup. Close Desktop Manager upon completion and unplug BlackBerry. You can get BlackBerry Desktop Software here http://us.blackberry.com/apps-software/desktop/
    3. Download the OS file from step 1 to the PC then install it to the PC by running (double clicking) the file you downloaded.
    4. Go to c:\program files\common files\research in motion\apploader and delete the file named "vendor.xml." Also check the following locations for vendor.xml files and delete any instances of the file:
    On Windows Vista/7 navigate to C:\Users\YOUR_USER\AppData\Roaming\Research In Motion\BlackBerry\Loader XML (Where "YOUR_USER" is your username)
    On Windows XP navigate to C:\Documents and Settings\YOUR_USER\Application Data\Research In Motion\BlackBerry\Loader XML (Where "YOUR_USER" is your username)
    5. If you're simply updating the OS to a newer version skip this step. If doing a clean OS reload use BBSAK from BBSAK.org and wipe the device (after doing a complete backup) then after you get the error 507 (no OS installed) then proceed to next step.
    6. Plug in BlackBerry and double click on "Loader.exe." It's located in c:\program files\common files\research in motion\apploader

  • What affects app startup time the most?

    If you find an app to startup slow, what would be the best way to speed it up? Is it the
    1) number of frameworks you linked?
    2) lines of code of your binary?
    3) images loading?
    4) objects loading? (Arrays, etc)
    5) navBar apps vs non navBar apps?
    6) file I/O?
    Any suggestions?

    It's pretty tough to answer your question since the answer depends entirely on what your app does and how it does it. The iPhone Programming Guide discusses several factors that affect performance. Giving that a read may be a good idea.

  • HT204266 what's app

    i purchase the what's app application and i cannot access it on the ipad
    i don't know what's wrong

    It won't be available on any iPad until the developers make an iPad-compatible version, at the moment it can only be installed on iPhones.

    Mainly Oracle apps dba also manage job like core dba, but apps dba also give support to application side(EBS). Apps dba can apply db patch and also apply application path. Apps dba monitor db activity&performance and also do samethink to application etc etc..

    Regards,
    AsifMy original comment aside, I find these comments from you rather, uh, "enlightening".
    "Which career is most rewarding one in terms of . . . Least amount of work"
    "which career will be . . . easy to learn"
    Since "easy" and "least work" seem important to you, I'd suggest a career in something besides IT. I could make some specific suggestions but run the risk of insulting people who work in those areas.

  • Role of Apps DBA in Implementing New Module

    Hi Friends,
    Supposing a company has a running smooth production system of EBS 11i. With modules
    FINANCIALS(GL,AR,AP,FA,CM) in it. Then the Company want to add another module HR system. Is an Apps DBA needed in the scenario? or only the SysAdmin and Functional
    Consultant only.
    What is the role of an AppsDBA in implementing a new module?
    Thank a lot

    It is the responsibility of both the System Administrator and the Apps DBA. If you need to change the status of HR module to fully installed, then you need to change the status from shared to fully installed (in case it is shared). You will also need to run DataInstall and apply hrglobal.drv driver using adpatch.

    or "oracle apps dba"
    These are not universal technical terms with clear meanings. ALL job titles mean only what the person/organization using them means for them to mean.
    Which will be good for you?
    Only you can decide that, based partly on the answer to my first question, and partly on what you want out of life. (And notice I said "what you want out of *life*", not what you want out of a job, or a career.)
