What is the exact difference between Database Cloning and Database Refresh?

Hi,
Can anybody tel me the exact difference between Database Cloning and Database Refresh?
I Have some conflicts in these topics.
Thanks
Rajesh

Refresh is what it says, "refresh" . You have a main site which would always have the data being inserted into it. There would be another site which would remain some where else . This site needs to be refreshed with the primary site. So you need to do export from the primary, push it to the secondary site and done!

  • What's the exact difference between "Query Def. Filter Value Selection" and

    Hi Gurus,
    what's the exact difference between "Query Def. Filter Value Selection" and "Query Execution Filter Val. Selectn" in info-object's "Business explorer" tab?
    I found out that if my info-object A has a input-ready variable in a query,after the query running,in  the selection screen,my info-object A's F4 value is follow the setting of "Query Execution Filter Val. Selectn",as the setting of "Query Def. Filter Value Selection" I tried every diff setting, it won't effect my query anyway.
    so:
    1.what's the exact difference between "Query Def. Filter Value Selection" and "Query Execution Filter Val. Selectn" in info-object's "Business explorer" tab?
    2.how they effect query's presentation?
    I searched forum,didn't find the answer what I want.
    Thanks everyone.

    Hi Denny,
    I will try to explain it again.
    Query Def. Filter Value Selection : Let say the value is set to "Only Values in Infoprovider"
    Lets take an example infoobject - 0MATERIAL (Material)
    Total material records in material Master = 1000 (master Data table /BI0/PMATERIAL)
    You create a query on top of an Infoprovider using Material.
    Total unique materials in Infoprovider= 500.
    Now when you are in design mode in Query Designer, and you try to restrict Material by few materials (for e.g. 1, 2, and 3), for this you right click on material and select Restrict, the pop-up opens with list of materials, this list is all those 500 materials which are in the infoprovider, because the setting is  "Only Values in Infoprovider". Which means then when you are trying to restrict a characterstic in query definition the list of values displayed for restricition is derived from Infoprovider.
    Query Execution Filter Value Selection  - I think you already know what it is , its the read mode for F4 help selection.
    I hope this helps.
    Thanks

  • Wat is the exact differences between clustered table and pooled table

    hi,
       can you tell me ravi...wat is the exact differences between clustered table and pooled table
    with regards//
    anilreddyg

    Hi Anil Reddy
    Pooled Tables, Table Pools, Cluster Tables, and Table Clusters
    These types of tables are not transparent in the sense that they are not legible or manageable directly using the underlying database system tools. They are managed from within the R/3 environment from the ABAP dictionary and also at runtime when they are loaded into application memory.Pool and cluster tables are logical tables. Physically, these logical tables are arranged as records of transparent tables. The pool and cluster tables are grouped together in other tables, which are of the transparent type. The tables that group together pool tables are known as table pools, or just pools; similarly, table clusters, or just
    clusters, are the tables which group cluster tables.Not all operations that can be performed over transparent tables can be executed over pool or cluster tables.
    For instance, you can manage these tables using Open SQL calls from ABAP, but not Native SQL.These tables are meant to be buffered and loaded in memory, because they are commonly used for storing internal control information and other types of data with no external (business) relevance. SAP recommends that tables of pool or cluster type be used exclusively for control information such as
    program parameters, documentation, and so on. Transaction and application data should be stored in transparent tables.
    Table Pools
    From the point of view of the underlying DBMS as from the point of view of the ABAP dictionary, a table pool is a transparent table containing a group of pooled tables which, when created, were assigned to this table pool.
    Field Type Description
    TABNAME CHAR(10) Table name
    VARKEY CHAR(n) Maximum key length n =< 110
    DATALN INT2(5) Length of the VARDATA record returned
    VARDATA RAW(m) Maximum length of the data varies according to DBMS
    Table Clusters
    Similarly to pooled tables, cluster tables are logical tables which, when created, are assigned to a table cluster. Therefore, a table cluster, or just cluster, groups together several tables of type clusters.Several logical rows from different cluster tables are brought together in a single physical record. The records
    from the cluster tables assigned to a cluster are thus stored in a single common table in the database.A cluster contains a transparent cluster key which must be located at the start of the key of all logical cluster tables to be included in the cluster. As well, a cluster contains a long field (VARDATA), which contains the
    data of the cluster tables for this key. If the data does not fit into a field, continuation records are created.
    Field Type Description
    CLKEY1 CHAR(*) First key fields
    CLKEY2 CHAR(*) Second key field
    CLKEYN CHAR(*) nth key field
    PAGENO INT2(5) Number of the next page
    TIMESTMP CHAR(14) Time stamp
    PAGELG INT2(5) Length of the VARDATA record returned
    VARDATA RAW(*) Maximum length of the data section; varies according to database system
    Working with Tables
    The dictionary includes many functions for working with tables. There are five basic operations you can perform on tables: display, create, delete, modify, copy. Please do not confuse displaying a table with displaying the table entries (table contents). In order to display a table, it must previously exist; otherwise the system will display an error message in the status bar. For the following example, the table TABNA is used. To display this table, from the main dictionary screen, enter the table name in the Object name
    input field with the radio button selected next to Tables. Then, click on the Display button at the bottom of the screen, or press the F7 function key, or, alternatively,
    select Dictionary object Display from the menu.
    In this screen, you can see table information such as
    ¨ Table type, shown next to the name of the object. In the example, it is a transparent table.
    ¨ Short text description.
    ¨ Name of the user who made the last change, and the date of the change.
    ¨ Master language.
    ¨ Table status. On the screen, you can see this table is saved and active.
    ¨ Development class. For information on development classes, refer to Chap. 6.
    Delivery class, which sets the maintenance group for the table. It controls how tables will behave during client copy procedures, upgrades, and so forth.¨
    Tab. Maint. Allowed flag, which indicates whether you can generate a screen for maintaining table entries.
    ¨Then, on the lower part of the screen, you can see the table fields with all associated characteristics such as:
    ¨ Field name.
    ¨ Key indicator. When set, this field is the primary key, or part of it.
    ¨ Data element.
    ¨ Basic data type.
    ¨ Length.
    ¨ Check table.
    ¨ Short text, describing the field.
    Additional information about the table can be displayed by selecting the corresponding functions from the menu or directly from the application toolbar, such as keys, indexes, or technical settings
    Standard table:
    The key access to a standard table uses a sequential search. The time required for an access is linearly dependent on the number of entries in the internal table.
    You should usually access a standard table with index operations.
    Sorted table:
    The table is always stored internally sorted by its key. Key access to a sorted table can therefore use a binary search. If the key is not unique, the entry with the lowest index is accessed. The time required for an access is logarithmically dependent on the number of entries in the internal table.
    Index accesses to sorted tables are also allowed. You should usually access a sorted table using its key.
    Hash table:
    The table is internally managed with a hash procedure. All the entries must have a unique key. The time required for a key access is constant, that is it does not depend on the number of entries in the internal table.
    You cannot access a hash table with an index. Accesses must use generic key operations (SORT, LOOP, etc.).
    Index table:
    The table can be a standard table or a sorted table.
    Index access is allowed to such an index table. Index tables can be used to define the type of generic parameters of a FORM (subroutine) or a function module.

  • What is the exact diff between  At New  and On Chnage

    hello all
    what is the exact diff between  At New  and On Chnage in control breaks statements. and when  shall we go for At new & when shall we go for On change on events.
    Plz tell with with some code.

    Hi ,
    Using at new
    Each time the value of c changes, the lines of code between at new and endat are executed. This block is also executed during the first loop pass or if any fields to the left of c change. Between at and endat, the numeric fields to the right of c are set to zero. The non-numeric fields are filled with asterisks (*). If there are multiple occurrences of at new, they are all executed. at end of behaves in a similar fashion.
    Using the on change of Statement
    Another statement you can use to perform control break processing is on change of. It behaves in a manner similar to at new.
    The following points apply:
    u2022     If the value of any of the variables (v1, v2, and so on) changes from one test to the next, the statements following on change of are executed.
    u2022     If no change is detected and else is specified, the statements following else are executed.
    on change of differs from at new in the following respects:
    u2022     It can be used in any loop construct, not just loop at. For example, it can be used within select and endselect, do and enddo, or while and endwhile, as well as inside get events.
    u2022     A single on change of can be triggered by a change within one or more fields named after of and separated by or. These fields can be elementary fields or field strings. If you are within a loop, these fields do not have to belong to the loop.
    u2022     When used within a loop, a change in a field to the left of the control level does not trigger a control break.
    u2022     When used within a loop, fields to the right still contain their original values; they are not changed to contain zeros or asterisks.
    u2022     You can use else between on change of and endon.
    u2022     You can use it with loop at it where . . ..
    u2022     You can use sum with on change of. It sums all numeric fields except the one(s) named after of.
    u2022     Any values changed within on change of remain changed after endon. The contents of the header line are not restored as they are for at and endat.

  • What is the main difference between f.13 and f13e

    Hi,
       What is the main difference between f.13 and f13e.
      when clearing the document do they follow deifferent steps in selection?
    Thanks,
    Sravanthi

    Hi,
    The reason "Clearing currency" is provided is because you can clear in any currency apart from local currency. For eg if your local currency is INR and Document currency (Invoice) is USD and the customer pays in EUR, you can still clear them with the Clearing currency EUR. On the date of payment, Open items in USD will be converted into Clearing currency EUR as follows: USD to INR and from INR to EUR. (based on exchange rates between USD-INR and INR-EUR).

  • What is the basic difference between Hyperion Planning and HFM

    Hi GURU'S,
    what is the basic difference between Hyperion Planning and HFM and when do we choose them.

    On a high level the difference is this:
    1. HFM is best for global collection (collecting data from scattered entities), group consolidation and for easily structuring financial reporting (mainly consisting of financial data)
    2. Planning is best for modeling your business, starting from a demand forecast and arriving to capacity planning and finally to financial statements, by utilizing business drivers (non-financial data like volumes, prices, productivity rates etc)
    Of course, differences may be analyzed at several levels down to technical, but the discussion may turn out to be too long, yet adding little value to the question: "when do we choose the one over the other". Bear in mind that your requirements may turn out that you need both.

  • What are the main differences between Signal Express and Labview?

    Howard,
    You clearly don't know what you are talking about. There is no "graphical version" of LabVIEW, there is just LabVIEW. Click on the article "Is LabVIEW a general purpose programming language?" written by the Jeff K. for some easy reading from a few years ago. It is all still true (except that object oriented features and recursion have been added in recent versions).
    One of the main points at this years NI-week was the discussion of how processor development is switching more and more to multicore designs  to improve performance because a simple boost in clock frequency is becoming more difficult. Linear, text based code is not well suited to take advantage of multticore design, while the dataflow based LabVIEW programming language automatically scales well to multiple processor cores, without any need to rewrite older code. I would say that only LabVIEW is futureproof in this respect. LabVIEW programmers are not wimps that are simply too stupid to write text based code. LabVIEW is not a toy language for people that don't want to learn a "real" programming language.
    LabVIEW is arguably the best programming language in terms of getting things done! I've never felt limited with LabVIEW and my programs often don't even have anything to do with data acquisition or instrument control. The difference between text based code vs. LabVIEW is like "DOS vs. Windows", "Radio vs. HD television". "Trilobyte vs. Homo sapiens" (sorry Putnam ). Text based code is monochrome, archaic and outdated and its linearity imposes unecessary constraints on the programmer that can only be (partially) overcome by wasting even more time throwing even more code at it.
    Sure, a seasoned text based programmer will initially have problems adapting to LabVIEW, just because you would need to adapt to and embrace the power of dataflow and not try to make a literal translation of the text code to LabVIEW, retaining old habits. If you get stuck, come back and ask here in the forum.
    You were looking for object oriented features and failed. All you need to do is a quick site search. All the information is out there. Just because you cannot find it in the first five sentences of the glossy brochure does not mean it does not exist. Maybe you want to read one of the application notes such as:
    LabVIEW Object-Oriented Programming: The Decisions Behind the Design
    In general, you should avoid judgement until you have all information. Your opinions seem quite biased and superficial and not really based on hard facts.
    Initially you asked about the difference between signal express and LabVIEW.

    No thanks, there has to be a better way to get an answer to my
    question than get involved in a two month study project.
    If you would answer the first question quoted above, we could certainly help you with the decision. Isn't that the main purpose of this thread?
    You can also contact your local LabVIEW Field Engineer to go over your requirements and help you make a decision. They usually know their stuff!

  • What are the main differences between 9 iAS and Oracle 8.1.7 ?

    My question is focus on JServ/JVM/EJB Deployment.
    1. They both provide Appach JServ to support JSP/Servlet application
    2. They both provide JVM 8i to support EJB 1.1.
    3. You can deploy JSP/Servlet application to JVM via mod_ose.
    4. On the White paper about 9 iAS, it says you can deploy applications into JDK JVM or Oracle 8i JVM, does that also apply to EJB? If so, how can you do it (with JDev 3.2 not some other command line tool?), it that one of the different between two products?
    5. Since 8.1.7, application server and database server were built into a package, why on 9i to separate them into two (or three) parts again? - what is the benefit for customers?
