Use database table in different system?

Hi, experts,
I am new to WD. I have a question here:
For example, now my WD application is in IB* system and the database table I need is in IS* system. I want to create functions in IB* system to operate the data from database table in IS* system and I will then use BAPI to call the created functions to transfer the results to WD. Is this possible?
Best Regards
Fan

Hi, Jagdish,
thank you for your reply. Do I need to do anything special to call the function module in another system? Or the WD wizard of making service call will automaticlly identify the position of the needed function module after i specify the name of the function module?
Best Regards
Fan

  • Thread pool and use database table as queue

    is this possible to use database table as queue rather than using "LinkedBlockingQueue"..and store in memory ? If yes, how do i serialized the task object into table and how to retrieve the task object back when need to be execute by executorservice..?

I would think in terms of messaging with JMS. There is one potential pitfall you may have to work around. JMS does not guarantee the order in which messages will be extracted from the queue. If the order of messages is important that is a problem you'll have to solve.

  • After compressed the database table affect the system performance

    There is a very big database table in my system called MSEG. It is about 910G and the wasted tablespace is about 330G. I want to compress the table, but the table is written and deleted frequently. will it affect the system performance if I compress the table. Or I can only select reorganize the dababase table avoid it affect the system performance? Thanks.

    Hi Huiyong,
    If you talk about table compression, it cannot be done online. we need to do this with a planned downtime. Table compression has some percentage of overhead on CPU. Refer SAP note for
    1289494
    FAQ: Oracle compression
    1436352
    Oracle Database 11g Advanced Compression for SAP Systems
    If you talk about online table reorg, yes definitely there would be impact on user performance.
    As the table size is very big it may take some days or hours to perform online Reorg.
    Other faster method is to perform table export import which is faster than online reorg. But it will again require downtime .
    Hope this helps.

  • Define hashed table using database table

    Hi,
    I have a database table and would want to define a hashed table using this table structure, how would I do that?
    Thanks
    RT

    Hi Rob,
    The syntax is as follows,
    DATA ITAB TYPE HASHED TABLE OF SPFLI
                   WITH UNIQUE KEY CARRID CONNID.
    The table object ITAB has the type hashed table, a line type corresponding to the flat structure SPFLI from the ABAP Dictionary, and a unique key with the key fields CARRID and CONNID. The internal table ITAB can be regarded as an internal template for the database table SPFLI. It is therefore particularly suitable for working with data from this database table as long as you only access it using the key.

  • Access SAP database table from different SAP server

    Hi,
    May i know is that possible to access the SAP database table from server A to server B without write a program on server A? Is it possible for direct access the SAP database table.
    Best regards,
    Gan

    Hello,
    you could use the RFC-Modules RFC_READ_TABLE or RFC_GET_TABLE_ENTRIES on server A.
    Precondition: you need a RFC-Destination from B to A.
    And a little drawback: you get only the first 512 byte of each table entry.

  • How can I list used database/table size resp user space ? Compression after

    How can I list used + maximum tablespace/database/table size of an Oracle database ?
    How can I list the space used currently by a user resp. his tables+indizes ?
    By the way: If I delete a user or table from an Oracle database installation: are then only the entires deleted

    Can anybody help me?
    Thanks in advance

    correct formatting...I wish you could edit your posts instead of reposting!
    Just a performance tip--> since it looks as though you are looping through and performing the same statement many times, you should consider using a prepared statement:
    PreparedStatement ps = con.prepareStatement("insert into Table1 (Col1,COl2,Col3) " +
    "values ( ? , ? , ? )");
    for (int k=0; j<array1.length; k++) {
    if (array1[k] !=null)
    tt = array1[k].getArray2();
    for (int j=0; j<50; j++) {
    if (array2[k] !=null)
    ps.setString(1, tt[j].getString1);
    ps.setString(2, tt[j].getString2);
    ps.setString(3, tt[j].getString3);
    ps.executeUpdate();You will notice a significant performance gain if you are looping many times.
    Advanced--> huge performance gain if you use batch statement in this loop!
    PreparedStatement ps = con.prepareStatement("insert into Table1 (Col1,COl2,Col3) " +
    "values ( ? , ? , ? )");
    for (int k=0; j<array1.length; k++) {
    if (array1[k] !=null)
    tt = array1[k].getArray2();
    for (int j=0; j<50; j++) {
    if (array2[k] !=null)
    ps.setString(1, tt[j].getString1);
    ps.setString(2, tt[j].getString2);
    ps.setString(3, tt[j].getString3);
    ps.addBatch();
    //when completed all looping
    int[] insertCount = ps.executeBatch();Jamie

  • Can moving large sharepoint lists to database and using database table as an external list help performance?

    Hi All,
    I have to maintain a huge SharePoint 2010 list with more than 700,000 items in it. The items are data records(not documents) and are distributed among a number of folders. There are also a number webparts that are currently using this list. As you can imagine
    the performance of queries on the list have degraded considerably. Even opening the folders with too many items in them takes quite some time. We are looking for a solution for this situation and some people suggested to move the list items to a SQL Server
    table and make an external list representing the original list. They think this way the changes that we have to make in the webparts source codes will be minimal.
    I am not sure if this is the best solution as I have heard about slow external lists. Do you think using the external list instead of our current list improves the performance? Do you think this is the right solution for us?
    I would be grateful if you tell me your ideas to solve this problem.
    Thanks in advance

    "right solution for us" is hard to solve without more info.
    SharePoint list items can include things like version history, content approval, audit tracking, and more... such things are NOT built into SQL.
    BCS is an option, and generally changing a list CAN have a very minimal impact (making many assumptions about how it's used)...
    BCS also incurs an overhead of the lookup (since it's external). And there are record limits (defaults at a minimum).
    And more importantly, SharePoint *can* handle large lists... if done appropriately... but can also be mis-handled.
    The limits imposed on large lists by SharePoint, are largely attributable DIRECTLY BACK TO SQL (specifically, the number of records that can be obtained with ROW locks before switching to PAGE locks or TABLE locks, which have LARGER impacts).
    So again, BCS is an option, but whether it's the "right solution for us" is more dependent. Plus, you would probably also benefit by spending some time investigating the other uses (web parts/etc) for opportunities to improve their performance,
    user experience, etc.

    Hi Steve,
    The endpoint would be the in the mxml file as part of the generated code. If you have used the service using the "Bind To Data" dialog, It would be part of the declarations tag in the mxml file as shown below.
    >>
    <YourService :YourService id="YourService" destination="YourService" endpoint="http://localhost/YourProject-debug/gateway.php" fault="Alert.show(event.fault.faultString)" showBusyCursor="true" source="yourService"/>
    <<
    The localhost needs to be changed to the server, where you are deploying your swf.Also the YourProject-debug folder to the directory under the webroot where you have copied the swf files and the corresponding php files.
    Hope this helps.

  • When using multiple tables in different sheets is it possible to delete cell/rows on all tables at the same time?

    I have recently changed from Excel to numbers and i can't  work out how to change cells. I have a sheet for each month, on that sheet i have all my outgoings on a daily basis. Those cells are the same in every table. In Excel i could hold shift and click the tab for each month and then change the information in all those cells. Can i do this in Numbers, if so how?

    This is not a feature of Numbers.

  • How to transport the DATABASE TABLE  into  the Test system ?

    Hi Experts,
    I am working on BI7,  I had created Database table in BDV system using SE11. Tech_name is ZGLACC_TEMP. I had activated it. I had used this database table for the purpose of  writing the start routine in the transformation. while I am transporting the transformations to the test system, It is showing as syntax error in ABAP program,
    In BDV system there are no syntax errors. it is working fine,
    So now I have to transport the database table to test system  so that I can transport the transformations into Test system without any error.
    Kindly anyone can give the answer , it will be appreciate and points will be assigned.
    thanks
    sekhar

    Hi Sekhar,
       Go to SE11, go into the change mode of your table and change the Object Directory entry (Goto -> Object Directory Entry) to some valid package (other than $tmp). Then it will ask for a transport request. Give a transport request and then I believe you know what to do with that transport.
       Another thing to keep in mind ... transport all the data elements and domains you have created for this table. Change their Object Directory Entry and assign them to the same transport request.
    Best regards,
    Kazmi

  • DBACOCKPIT - MSSQL Named Instance, RFC and DB Connection different systems

    Hello All,
    SAP is installed as a Central Server. Database and Central instance on a single host with the database on a Named Instance.
    I have configured the dbacockpit as per SAP Note 1388700 - SQL Server Remote Database Monitor in Solution Manager 400 for my Named Instances. I have a working database connection %_<SID>_<HOSTNAME> with the DBCO Connection Info referencing the MSSQL_SERVER as <HOSTNAME>\<SID>. Full line:
    MSSQL_DBNAME=<SID> MSSQL_SERVER=<HOSTNAME>\<SID> OBJECT_SOURCE=SAPSolMan710
    In dbacockpit now as an additional action I try to edit the connection. I select the checkbox by RFC destination, first message with a Red LED is 'This is not the local system, please specify a RFC destination. I select any RFC destination referencing the host, even custom made ones. The response after logging in to the target (when not using Trusted RFC) is always the same.
    'Red LED', SMP, RFC destination and database connection describe different systems.
    In the home screen of dbacockpit if you now select 'SLD System Import' the systems with a Named Instance are still available under 'New Database Systems in the SLD'.
    Now edit the system again, remove the RFC destination and Save. This will write to the SLD.
    If you now log in to the SLD, Administration, Content Maintenance, 'Class' Database Systems you will now have a new System with 0(zero) associations. This system has SystemHome = <HOSTNAME>\<SID> as such it will not match to the SAP System. I have edited the Database in SMSY to directly reference the Database connection but even this does not help
    Has anyone come accross this? What is the resolution?

    Hi,
    Could you please post the errors that appears while configuring in the DBACOCKPIT t code at the bottom of the screen?
    According to that we can determine, whether it is able connect the database correctly or not.
    Cheers

  • Authentication & Authorization with SSO, JAAS and Database Tables mix

    Hi,
    I'm looking for how manage Authentication & Authorization in a J2EE ADF+Struts+JSP application.
    I'm interested in use SSO for authentication (I just did it programatically & dynamically already), and now I would like to could define authorization using database tables with users, groups, profiles, individual permissions, ..., (maitanined dynamically by web application admin) throught JAZN (JAAS or however is said) but not statically defining roles, groups, users, ... in jazn xml files.
    I saw that exists the possibility to create a custom DataSourceUserManager class to manage all this, and this gave me the idea that this could be possible to do (I was thinking in make a custom Authorization API over my application tables, without JAZN) but what is better that use and extended and consolidated aprox like JAZN.
    Anybody could tell me if my idea could be possible, and realizable, and maybe give me some orientation to build this approach.
    A lot of thanks in advanced.
    And sorry, excuse my so bad english.
    See you.

    Marcel,
    Originally the idea was to create a post to only explain how to do authentication using a Servlet filter. However,
    I have recently added code to the JHeadstart runtime and generators to enable both JAAS and 'Custom' authentication AND authorization in generated applications. Therefore, this post will be made after we have released the next patch release, as it will depend on these code changes.
    We currently plan to have the patch release available sometime in the second half of May.
    Kind regards,
    Peter Ebell
