  • What is difference between 32 bit and 64 bit sql server memory management

    What is difference between 32 bit and 64 bit sql server memory management
    Thanks
    Shashikala

    This is the basic difference...check if helps:
    A 32-bit CPU running 32-bit software (also known as the x86 platform) is so named because it is based on an architecture that can manipulate values that are up to 32 bits in length. This means that a 32-bit memory pointer can store a value between 0 and
    4,294,967,295 to reference a memory address. This equates to a maximum addressable space of 4GB on 32-bit platforms
    On the other hand 64-bit limit of 18,446,744,073,709,551,616, this number is so large that in memory/storage terminology it equates to 16 exabytes. You don’t come across that term very often, so to help understand the scale, here is the value converted to
    more commonly used measurements: 16 exabytes = 16,777,216 petabytes (16 million PB)➤ 17,179,869,184 terabytes (17 billion TB)➤ 17,592,186,044,416 gigabytes (17 trillion GB)➤
    As you can see, it is significantly larger than the 4GB virtual address space usable in 32-bit systems; it’s so large in fact that any hardware capable of using it all is sadly restricted to the realm of science fiction. Because of this, processor manufacturers
    decided to only implement a 44-bit address bus, which provides a virtual address space on 64-bit systems of 16TB. This was regarded as being more than enough address space for the foreseeable future and logically it’s split into an 8TB range for user mode
    and 8TB for kernel mode. Each 64-bit process running on an x64 platform will be able to address up to 8TB of VAS.

  • Difference between target schema and target user

    hi,
    Can anyone explain to me what is the difference between target schema and target user? examples will be more welcome then theoratical explanation.
    thanks so much

    In Oracle database schema and user is the same things (if you use general authentication by database).
    When used external authentication (for example with Windows domains/active directory) schema is a owner of database objects group and you should specify mapping between external usernames and schema to which this user has access when connects to database.
    For example:
    - windows domain user CORPDOMAIN\USER1 can connect to oracle database schema SCOTT;
    - windows domain user CORPDOMAIN\USER2 can connect to oracle database schema SCOTT;
    - windows domain user CORPDOMAIN\ADMIN can connect to oracle database schema SYSTEM;

  • What is difference between bex analyser and bex browser

    what is difference between bex analyser and bex browser . please explain what are use of both and what we do in both.

    hi
    Bex Browser
    The Business Explorer Browser (BEx Browser) makes it possible for you to access all document types of the Business Information Warehouse that are assigned to your role or that you have stored in your favorites. You can select and open documents assigned to you in the BEx Browser or store and manage new documents in the BEx Browser.
    Document types that you can work with in the BEx Browser are:
    · BW workbooks
    · Documents that are stored in the Business Document Service (BDS)
    · Links (references to file system, shortcuts)
    · Links to internet sites (URLs)
    · SAP transaction calls.
    · Web applications and Web templates
    · Crystal Reports
    Bex Analyser
    The Business Explorer Analyzer (BEx Analyzer) is the analysis and reporting tool of the Business Explorer that is embedded in Microsoft Excel.
    Features
    You can call up the BEx Query Designer in the BEx Analyzer, in order to define queries. Subsequently, you can analyze the selected InfoProvider data by navigation to the query created in the Query Designer and create different query views of the data. You can add the different query views for a query or for different queries to a work book and save them there. You can save the workbook in your favorites or in your role on the BW Server. You can also save the workbook locally on your computer.
    Beyond that, you can precalculate the workbook and distribute it by e-mail to recipeients or you can export it to the Enterprise Portal and make it accessible to other employees in the company.
    You can start queries in a standard view (with a Standard Web Template set up in Customizing) in the Web browser and forward the URL or continue to navigate on the Web. Similarly, you can export the Web query to MS Excel 2000.
    Overview of the Functional Area of the BEx Analyzer:
    ·        BEx toolbar
    You access the functions of the BEx Analyzer from the BEx toolbar, which takes you to the BEx Open dialog box where you can open existing queries, or to the BEx Query Designer where you can create new queries or change existing queries.
    ·        Evaluating Query Data
    The BEx Analyzer offers convenient functions for evaluating and presenting InfoProvider data interactively. In the BEx Analyzer, you can add queries to workbooks, navigate within them and refresh the data. You can also process the queries further in Microsoft Excel or display them in the Web browser in a default view.
    Navigation of a query allows you, for example, to filter characteristics on a single value, drilldown on all values for a characteristic, regroup characteristics and key figures in the rows and columns of the results area, or hide key figures. Navigation results in different views of the InfoProvider data. In addition, a range of further functions is available which allow you to edit a query interactively (for example, sorting, cumulated output, among others). In addition, you can use the editing functions in Microsoft Excel in order to set up individual format templates, to print results areas, or to create graphics.
    ·        Queries in Workbooks
    Queries are inserted into workbooks so you can display them. When you insert a query, a link is made between the cell areas of the worksheet and the data of the InfoProvider upon which the query is based. A link therefore exists between the Business Explorer and the Business Information Warehouse Server (BW Server).
    When inserting a query into the workbook, a VBA routine is automatically generated in the workbook. You can also connect the Business Explorer with your own VBA programs (Visual Basic for Applications).
    You can create workbook templates, into which you can insert your queries. Workbook templates can contain pre-determined items for the area of the query, formatting settings, logos, VBA macros, and so on.
    ·        Precalculating workbooks
    You can precalculate and distribute workbooks with the BEx Broadcaster, which is a Web application you get to form the BEx toolbar. The system generates MS Excel workbooks with historical data. You determine the time for precalculation yourself: You can have workbooks precalculated at a predefined time or they can be precalculated whenever data in the underlying InfoProvider changes. You can have the precalculated workbooks sent by e-mail or you can export them into the Enterprise Portal, where you can make them available to employees within your company.
    Activities
    To start the BEx Analyzer, choose Start ® Programs ® SAP Front-end Business Information Warehouse ® SAP Business Explorer Analyzer.
    You can also access the BEx Analyzer via SAP Easy Access ® SAP Business Information Warehouse ® SAP Menu ® Business Explorer ® Analyzer or in the Business Explorer Browser using the Business Explorer Analyzer symbol in the menu bar.
    Hope this will solve your issu

  • What is difference between report programming and dialog programming?

    hi,
    what is difference between report programming and dialog programming? plz provide some example code
    bye

    ABAP programming
    Basically reports are used to read database and represent the results in lists.
    Reports are collections of processing blocks that the system calls depending on events.
    We can use reports to evaluate data from database tables.
    Reports are stand alone programs and controlled by events.
    A report itself never creates events
    steps in report:
    Processing the selection screen
    Reading the database
    Evaluating the data and creating lists
    Outputting a list.
    1st u write simple logics, after that u can enhance the code as step by step.

    Dialog Programming
    Structure of a Dialog Program
    A dialog program consists of the following basic components:
    Screens (dynpros)
    Each dialog in an SAP system is controlled by dynpros. A dynpro (DYnamic PROgram) consists of a screen and its flow logic and controls exactly one dialog step. The flow logic determines which processing takes place before displaying the screen (PBO-Process Before Output) and after receiving the entries the user made on the screen (PAI-Process After Input).
    The screen layout fixed in the Screen Painter determines the positions of input/output fields, text fields, and graphical elements such as radio buttons and checkboxes. In addition, the Menu Painter allows to store menus, icons, pushbuttons, and function keys in one or more GUI statuses. Dynpros and GUI statuses refer to the ABAP/4 program that control the sequence of the dynpros and GUI statuses at runtime.
    ABAP/4 module pool
    Each dynpro refers to exactly one ABAP/4 dialog program. Such a dialog program is also called a module pool, since it consists of interactive modules. The flow logic of a dynpro contains calls of modules from the corresponding module pool. Interactive modules called at the PBO event are used to prepare the screen template in accordance to the context, for example by setting field contents or by suppressing fields from the display that are not needed. Interactive modules called at the PAI event are used to check the user input and to trigger appropriate dialog steps, such as the update task.
    All dynpros to be called from within one transaction refer to a common module pool. The dynpros of a module pool are numbered. By default, the system stores for each dynpro the dynpro to be displayed next. This dynpro sequence or chain can be linear as well as cyclic. From within a dynpro chain, you can even call another dynpro chain and, after processing it, return to the original chain.

    To make things clear, here are two small examples that show how nasty locals and value properties can be to the naive programmer.
    - Open the diagram of the race condition.vi before running it and try to predict what will be the values of the two counters after the third run.
    - Use the Compare Locals Properties and Wires.vi to find out how slow locals and value properties can be (times 1000+).
    This being demonstrated, I must add that I use globals and value properties quite often, because they are often very convenient

  • What is difference between Shared ,Exclusive and Exclusive but not commulat

    what is difference between Shared ,Exclusive and Exclusive but not commulative lock modes plese tell me

    Lock objects are used to synchronize access to the same data by more than one program.
    The lock mode controls whether several users can access data records at the same time. The lock mode can be assigned separately for each table in the lock object. When the lock is set, the corresponding lock entry is stored in the lock table of the system for each table.
    There are three types of lock modes
    1.Exclusive
    2.Shared
    3.Exclusive not cummulative
    Exclusive lock: The locked data can only be displayed or edited by a single user. A request for another exclusive lock or for a shared lock is rejected.
    Shared lock: More than one user can access the locked data at the same time in display mode. A request for another shared lock is accepted, even if it comes from another user. An exclusive lock is rejected.
    Exclusive but not cumulative: Exclusive locks can be requested several times from the same transaction and are processed successively. In contrast, exclusive but not cumulative locks can be called only once from the same transaction. All other lock requests are rejected.
    please go through these links:

    briefly :
    You can lock the table or record by using following types of locking:
    1) Exclusive (E) the locked data can only be displayed or modified by single user i.e the owner of the object. Access to other users is denied.
    2) Shared (S) several users can access the same record simultaneously, but only in display mode and except the first one, who has asked for the data in update mode.
    3) Exclusive not cumulating (X) it is similar to exclusive lock. It allows only a single user access. E can be called several times from the same transaction. In contrast, a lock type X can be called only once during the transaction. Any other call for this lock is rejected.
    Activation of Lock Object
    1) When you activate the lock object, the functions are automatically generated. And these are ENQUEUE-EZN and DEQUEUE-EZN. EZN is name of the lock object.
    2) While ENQUEUE is used in program to set the code over the selected data depending upon the lock object arguments. DEQUEUE is used to release the lock.

  • What is difference between Managed Bean and Backing Bean?

    What is difference between Managed Bean and Backing Bean? Please guide me how to create them and when to use them?
    Please post sample for both beans.

    Hi,
    managed beans and backing beans are quite the same in that the Java object is managed by the JavaServer Faces framework. Manage in this respect means instantiation. The difference is that backing beans contain component "binding" references, which managed beans usually don't. Do backing beans are page specific versions of managed beans.
    Managed beans are configured either in the faces-config.xml file, or using ADF Faces and ADFc, in the adfc-config.xml file

    what is difference between table space and shchema ?

    784633 wrote:
    so each user has it own space of tables - schema ?yes, but let's clarify a bit ....
    The "schema" is the collection of all objects owned by a particular user. So if user SCOTT creates two tables, EMP and DEPT, and a view EMP_RPT, and a procedure GET_MY_EMP, those objects (tables, views, procedures) collectively make up the SCOTT schema.
    Those objects will be physically stored in a tablespace.
    A tablespace is a named collection of data files. So tablespace USERS will be made up of one or more data files. A specific datafile can belong to one and only one tablespace. If a tablespace has more than one data file, oracle will manage those files as a collection invisible to the application - much like the OS or disk subsystem handles striping across multiple physical disks.
    A specific object in the SCOTT schema can exist in only one tablespace, but not all objects of the schema have to be in the same tablespace. Likewise a tablespace can contain objects from multiple schemas.
    and can one user to access tables of other users?As others have said - FRED can access tables belonging to SCOTT as long has SCOTT has granted that access to FRED.

  • Whats the difference between arrayCollection = null and arrayCollection.removeAll()?

    Whats the difference between arrayCollection = null and
    arrayCollection.removeAll()?

    In arrayCollection = null; statement you're setting this
    reference to null and potentially making it available for garbage
    collection. I say 'this reference' and potentially because, as you
    may know, there might be other references to this array collection
    object that won't be affected by this statement and hence it won't
    be GC'ed.
    arrayCollection.removeAll() says that I want to empty this
    array collection for all the reference that we pointing to it. That
    is, remove all the objects from the collection -- and of course
    make them 'potentially' available for the GC -- the size of the
    array collection would be reduced down to zero and all the
    references would be pointing to a valid but empty collection.
    Hope this helps.

    Also when I upgrade does it have to be with a monthly membership or can I just purchase the product out right like you use to be able?

    You cannot "update" from what you have to any of the applications you mention. It will have to be a straight purchase or subscription at full price.
    Photoshop is a professional level application that makes no apologies for its very long and steep learning curve.
    Lightroom is all about volume, and very light editing.

  • Differences between rate routing and reference rate routings?

    Hello PP members:
    I would like to differences between rate routing and reference rate routings
    Thanks for your time,
    Thanks Again,
    Suren R

    Hi Mr.Suren,
    As explained by other friends Routing is used in Discrete manufacturing and Rate routing is used for REM-Repetitive manufacturing.
    In addional to these types SAP has given 2 more types
    1.Reference operation set -Used in Discrete manufacturing.
    2.Reference rate routing - Used in REM.
    If similar rate routing is been used for producing many materials,then instead of entering(these steps) in rate routing of each  material you create a refrence rate routing and you enter the work centres used and the other details.After saving you get a group counter number showing reference rate routing is saved with group XXXXXXXXX.
    When you are creating rate routing for a material say A ,after giving the name and plant details in the top you will be able to see an icon "copy from" and you can select the radio button for reference rate routing and give the group counter number. or else without giving it here you have got an option to select the reference rate routing after entering into the operation screen also.
    In that particular page in operation overview screen,there will be an icon copy,there you can click that icon and you can give the reference rate routing group counter number and very easily you can create rate routing for N number of material.
    Likewise you can use reference operation set while creating routing for a material in Discrete manufacturing.This basically reduces the time in creating routing or rate routing for materials in Discrete & REM respectively
    CA01,CA02,CA03-Create,Change,display (routing)  respectively.
    CA11,CA12,CA13-Create,Change,Display reference operation set Respectively.
    CA21,CA22,CA23-Create,Change,Display rate routing respectively.
    CA31,CA32,CA33-create,change,display reference rate routing resp.
    I hope this will help you.
    If useful reward your points.
    Thanks & regards
    Karthik.
