Diff between Application DBA and System DBA

Hi All,
I have just started my DBA career.
Can anyone let me know the differences between a Application DBA and System DBA

asked soooooo many times already...
Basically an application server has more functionality than a webserver, such as enterprise javabeans. That is assuming we are taking about a java webserver like Tomcat.

    SAP LANDSCAPE:
    Landscape is like a server system or like a layout of the servers or some may even call it the architecture of the servers viz. SAP is divided into three different lanscape DEV, QAS and PROD.
    DEV would have multiple clients for ex: 190- Sandbox, 100- Golden, 180- Unit Test.
    QAS may again have mutiple clients for ex: 300- Integration Test, 700 to 710 Training.
    PROD may have something like a 200 Production.
    These names and numbers are the implementer's discreet on how they want it or they have been using in their previous implementations or how is the client's business scenario.
    Now whatever you do in the Sandbox doesn't affect the other servers or clients. Whenever you think you are satisfied with your configuration and you think you can use it moving forward, you RE-DO it in the golden client (remember, this is a very neat and clean client and you cannot use it for rough usage).
    As you re-do everything that you had thought was important and usable, you get a transport request pop up upon saving everytime. You save it under a transport request and give your description to it. Thus the configuration is transported to the Unit Test client (180 in this example).
    You don't run any transaction or even use the SAP Easy Access screen on the 100 (golden) client. This is a configuration only client. Now upon a successful tranport by the Basis guy, you have all the configuration in the Testing client, just as it is in the Golden client. The configuration remains in sync between these two clients.
    But in the Testing client you can not even access SPRO (Display IMG) screen. It's a transaction only client where you perform the unit test. Upon a satisfactory unit test, you move the good configuration to the next SERVER (DEV).
    The incorrect or unsatisfactory configuration is corrected in Golden (may again as well be practised in the sandbox prior to Golden) and accordingly transported back to 180 (Unit Test) until the unit test affected by that particular config is satisfactory.
    The Golden client remains the 'database' (if you wanna call it that) or you may rather call it the 'ultimate' reference client for all the good, complete and final configuration that is being used in the implementation.
    In summary:
    Landscape : is the arrangement for the servers
    IDES : is purely for education purpose and is NOT INCLUDED in the landscape.
    DEVELOPMENT ---> QUALITY -
    > PRODUCTION
    DEVELOPMENT : is where the the consultants do the customization as per the company's requirement.
    QUALITY : is where the core team members and other members test the customization.
    PRODUCTION : is where the live data of the company is recorded.
    A request will flow from Dev->Qual->Prod and not backwards.
    1. Sandbox server:
    In the initial stages of any implementation project, You are given
    a sandbox server where you do all the configuration/customization as per the companies business process.
    2. Development Server:
    Once the BBP gets signed off, the configuration is done is development server and saved in workbench requests, to be transported to Production server.
    3. Production Server:
    This is the last/ most refined client where the user will work after project GO LIVE. Any changes/ new develpoment is done is development client and the request is transported to production.
    These three are landscape of any Company. They organised their office in these three way. Developer develop their program in Development server and then transport it to test server. In testing server tester check/test the program and then transport it to Production Server. Later it will deploy to client from production server.
    Presentaion Server- Where SAP GUI have.
    Application Server - Where SAP Installed.
    Database Server - Where Database installed.
    What is the meaning of "R" in R/3 systems?
    R/3 stands for realtime three tier architecture. This is the kind of architrecture SAP R/3 system has.
    R/3 means three layers are installed in Different system/server and they are connected with each other.

  • Differences between infrastructure dba and production dba

    Hi DBAs,
    I have graduated and interested in heading into dba path.
    I heard there's 2 kind of dba, infrastrucrue dba and production dba. can anyone advise what's the differences as i'm new to working society?
    heard that the infrastructure dbas are actually task to setup the database infrastructure in r&d environment and tested it before deploying it to production site through raising instructions for production dba to do it. Most of the their time is commited to co-ordinate project between the application team and production team.
    please advise.
    thanks

    Infrastructure is the same as a development DBA sort of.....
    But Infrastructure sort of Architects the system too. Think of a RAC system. He might recommend the RAC, design the interconnects, decide what storage and HBA's to use. You get the idea.
    Production is the one who gets pages when the system goes down. They generally maintain the system day to day and apply patches, setup backups etc...

  • What are application events and system events? what is difference between ?

    what are application events and system events? what is difference between ?

    The Control Framework triggers the event irrespective of the screen flow logic, that is, without processing the PAI and PBO events. These events are called system events. This type of event processing is the default setting.
    ·The Control Framework processes the PAI module after an event. In this case, you must call method CL_GUI_CFW=>DISPATCHto initiate the event handling of ABAP Objects. These events are called application events.
    Application Event : you must first register the events for the control instance and consequently on the frontend.
    like..
    DATA events TYPE cntl_simple_events.
    DATA wa_events TYPE cntl_simple_event.
    1. Using field
    appl_event , define the event as an application event:
    wa_events-appl_event = 'X'.
    System events are passed on irrespective of the flow logic of the relevant screen.
    1. Change the value of field
    wa_events-appl_event in the PBO module:
    wa_events-appl_event = SPACE.

  • In LSMW, what is diff between LSMW-BAPI and LSMW-IDOC

    hello all
    In LSMW, what is diff between LSMW-BAPI and LSMW-IDOC

    Hi Swamy,
    The differences between IDoc and BAPI are as follows: 
    IDOC
    IDocs are text encoded documents with a rigid structure that are used to exchange data between R/3 and a foreign system.
    Idocs are processed asynchronously and no information whatsoever is returned to the client.
    The target system need not be always online. The IDOC would be created and would send the IDOC once the target system is available (tRFC concept). Hence supports guaranteed delivery.
    With asynchronous links the sub-process on the client can be finished even if the communication line or the server is not available. In this case the message is stored in the database and the communication can be done later.
    The disadvantage of asynchronous links is that the sub-process on the server cannot return information to the calling sub-process on the client. A special way for sending information back to the client is required. In addition, a special error handling mechanism is required to handle errors on the receiving side.
    IDOCs may be more changeable from release to release.
    IDOCs  are poorly documented.
    BAPI
    BAPIs are a subset of the RFC-enabled function modules, especially designed as Application Programming Interface (API) to the SAP business object, or in other words: are function modules officially released by SAP to be called from external programs.
    BAPIs are called synchronously and (usually) return information.
    For BAPIs the client code needs to do the appropriate error handling.
    Problems with synchronous links occur if the communication line or the server is temporarily not available. If this happens, the sub-process on the client cannot be finished (otherwise there would be data inconsistencies).
    Synchronous links have the advantage that the sub-process on the server can return values to the sub-process on the client that has started the link.
    BAPIs are not totally immune to upgrades.
    BAPIs are reasonably well documented.
    Reward points if useful.

  • Diff between sap query and abap query

    diff between sap query and abap query

    Hi,
    ABAP query is mostly used by functional consultants.
    SAP Query :
    Purpose
    The SAP Query application is used to create lists not already contained in the SAP standard system. It has been designed for users with little or no knowledge of the SAP programming language ABAP. SAP Query offers users a broad range of ways to define reporting programs and create different types of reports such as basic lists, statistics, and ranked lists.
    Features
    SAP Query's range of functions corresponds to the classical reporting functions available in the system. Requirements in this area such as list, statistic, or ranked list creation can be met using queries.
    All the data required by users for their lists can be selected from any SAP table created by the customer.
    To define a report, you first have to enter individual texts, such as titles, and select the fields and options which determine the report layout. Then you can edit list display in WYSIWYG mode whenever you want using drag and drop and the other toolbox functions available.
    ABAP Query,:
    As far as I Believe, is the use of select statements in the ABAP Programming. This needs a knowledge of Open SQL commands like Select,UPdtae, Modify etc. This has to be done only by someone who has a little bit of ABAP experience.
    To sum up, SAP queries are readymade programs given by SAP, which the user can use making slight modification like the slection texts, the tables from which the data is to be retrieved and the format in which the data is to be displayed.ABAP queries become imperative when there is no such SAP query existing and also when there is a lot of customizing involved to use a SAP Query directly
    use either SQ02 ans SQ01
    or SQVI tr code
    for more information please go thru this url:

  • Diff between Thin client and Rich client

    Hi Everyone,
              Can someone give me a clear picture of the what is the diff between Thin client and Rich client.
    Thanks,
    Krishna

    Hi,
    thick client (rich client) has/stores all the data inside itself
    so it can do application processing without the server with data
    thin client uses resources from host computer (from server)
    and wihtout that you are not able to work with that kind of client
    does that answer your question ?

  • What exactly is the diff between main window and variable window

    what exactly is the diff between main window and variable window in SAP script?

    hi,
    MAIN WINDOW :- In a main window you display text and data, which can cover several pages (flow text). As soon as a main window is completely filled with text and data, the system continues displaying the text in the main window of the next page. It automatically triggers the page break.
    You can define only have one window in a form as main window.
    The main window must have the same width on each page, but can differ in height.
    A page without main window must not call itself as next page, since this would trigger an endless loop. In such a case, the system automatically terminates after three pages.
    VARIABLE WINDOW :- The contents of variable windows is processed again for each page, on which the window appears. The system outputs only as much text as fits into the window. Text exceeding the window size is truncated; the system does not trigger a page break. Unlike constant windows, the page windows declared as variable windows may have different sizes on different form pages.
    As far as the processing of the window contents is concerned, the system currently treats constant and variable windows alike. The only difference is that constant windows have the same size throughout the form.
    hope this will be useful.
    If useful then reward points.
    with regards,
    Syed

    Hi Shreya,
       Update queue(LBWQ) comes into the picture when you choose Queued Delta for the Datasource. the data first comes to the Update queue and than goes to the Delta queue, however if you have choosen Direct Delta than the posted record will directly go to the Delta queue(RSA7).

  • Difference between Application.CurrentCulture and Thread.CurrentCulture

    Can someone tell me the difference between Application.CurrentCulture and Thread.CurrentCulture.
    Thread has CurrentCulture and CurrentUICulture. But Application has only CurrentCulture. Why?
    (https://msdn.microsoft.com/en-us/library/system.windows.forms.application.currentculture(v=vs.110).aspx)
    (https://msdn.microsoft.com/en-us/library/system.threading.thread.currentculture(v=vs.110).aspx)

    1)
    Application.CurrentCulture delegates to Thread.CurrentThread.CurrentCulture("Gets or sets the culture information for the current thread") so it only sets it for the main thread of the
    application.
    2) They are both properties of a Thread object, which you can access via Thread.CurrentThread.
    CurrentCulture – Tells you the user’s current locale, as set in the Region
    applet.  I.e.: Where is the user located?
    CurrentUICulture – Tells you the native language of the version of Windows
    that is installed.  I.e.: What language does the user speak?
    The user can change CurrentCulture using the Region applet.  It’s used to determine formatting for numeric and date/time
    strings.

  • Difference between application server and central instance

    whats the difference between application server and central instance and message server. where it will be installed. and how?
    Regards
    Basis Fresher

    Hi,
    just want to clarify that is is not correct that only one enqueue process can be configured on the CI.
    Please see the documentation within transaction RZ11 for the parameter Parameter : rdisp/wp_no_enq
    Short description : number of enqueue work processes
    Parameter description :
    You can use this parameter to define the number of enqueue work processes for the instance.
    Ensure that a value >0 is only set on the central instance that provides the enqueue server (instance rdisp/enqname ). One enqueue work process on the central instance is normally sufficient (rdisp/wp_no_enq = 1); only in very large systems can a higher value be useful.
