How to decrease the OLAP/DB and Frontend time of query

Hi,
While  I am excuiting the query, it takes time to dispaly the query output. Reason behind is it have the high OLAP/DB and Front end time.
Can anyone help me how to decrease the OLAP/DB and Front end time.
Regards,

Probably Existing Aggregates are not useful .. you can edit them based on below factors
You can also check ST03N - > BI Workload - > select Weekly/Monthly - >Choose All data tab - >dbl click on Infocube - > choose query - > check the DB time % > 30% and Aggregation ratio is > 10 % then create aggregates.
Now goto RSRT choose query - > Execute debug mode - > check 'Display Aggr found' and choose 'Display Stats' -> now you can check records selected Vs records transferred in % .. it should be > 10 % .. That means the query is fetching records from Aggrs which will also improve query performance!
Also check RSRT - Execute in Debug and choose display aggregates found.. If it found aggregates then the query is using/fetching data from aggr's

  • How to decrease the column length in working time (CATS) table

    Hi all,
    Can you please tell me how we can decrease the column length in CATS table in the portal. Is it something we can do in webdynpro or in the back end.
    Thanks in advance.

    I was looking for something similar and ran across OSS Note 989453. I would recommend checking out this note to see if it helps. Apparently, there is a JAVA program error that makes the columns wider than they need to be.
    We have not yet tried this so if you happen to use it, let me know how it works for you.

  • How to decrease the dynamic table data loading time

    hi
    i have problem with dynamic table.
    when i execute the the table with passing a query , getting lot of time for loading the table data.( it takes 30sec for every 100 rows.)
    pls help me how to overcome this problem.
    thanks advance.

    Yes, This is oracle application...
    We can move into other tablespace as well. But concern is how to improve the alter table move command performance.
    Is there any specific parameter apart from the nologging and parallel server..
    If it is taking 8 hours , can some have experience that nologging will save how much time. or is there any risk in doing in production.

  • How to decrease the width of left column in the "2 column layout"?

    Hi all,
    I create two webdynpro based iViews in the EP, then I create a page use the "2 column layout(Narrow:Wide)".I put one iview in the left column and another iview in the right column. When I preview my page, I found the left column still too wide. So how to decrease the width of my page's left column?
    Thanks and Best regards
    Deyang

    Hi Deyang,
    You have to create your own layout:
    - Navigate to System Administration->Support
    - Choose Portal Runtime -> Browse Deployment
    - Navigate under pcd or under temp, and download the layouts par (com.sap.portal.layouts.default.par.bak if I recall correctly)
    - Import that par as a project to Developer Studio
    - Make your changes (create a new jsp acording to the existing examples, and update the portalapp.xml accordingly)
    - Export to par (in a different name!) and deploy
    - In the portal content: new from par -> Layout (don't forget to mark it as a template).
    - Your new layout template will now be available when you create new pages.
    good luck!

  • How to decrease the row height in ALV Grid (OOPS).

    HI Experts,
    I have displayed ALV Grid using CL_GUI_ALV_GRID=>SET_TABLE_FOR_DISPLAY.
    I want to decrease the row height and width.
    Can any one suggest how to do this?
    Regards,
    Kumar.

    Hi Kumar,
    Row height it predefined and you won't change it, but you can adjust column width.
    For that use field COL_OPT of layout structure ( type LVC_SLAYO ) to optimize all columns width, or set explicit width using field catalog, setting field OUTPUTLEN for certain column.

  • How to decrease the storage in macbook air

    how to decrease the storage in macbook air ?

    you mean decrease all the files filling your Air?
    See here for answer about the OTHER which is taking up space:
    http://pondini.org/TM/30.html
    and here:
    http://pondini.org/OSX/DiskSpace.html
    See Kappys excellent note on the rest of “other” files taking up your space:
    What is "Other" and What Can I Do About It?
    In the case of a Macbook Air or Macbook Pro Retina with ‘limited’ storage on the SSD, this distinction becomes more important in that in an ever rapidly increasing file-size world, you keep vital large media files, pics, video, PDF collections, music off your SSD and archived on external storage, for sake of the necessary room for your system to have free space to operate, store future applications and general workspace.  You should never be put in the position of considering “deleting things” on your macbook SSD in order to ‘make space’.
    Professionals who create and import very large amounts of data have almost no change in the available space on their computers internal HD because they are constantly archiving data to arrays of external or networked HD.
    Or in the case of the consumer this means you keep folders for large imported or created data and you ritually offload and archive this data for safekeeping, not only to safeguard the data in case your macbook has a HD crash, or gets stolen, but importantly in keeping the ‘breathing room’ open for your computer to operate, expand, create files, add applications, for your APPS to create temp files, and for general operation.

  • How to decrease the latency with flash+http+camera video?

    I build a HTTP server between live camera and flash player. The flash player connect http server with NetStream. But i find there is a long latency and NetStream doesn't decode frames when the buffersize reach a special value. So i want to know, how to decrease the latency in those environment?
    And why the frame cannot be decoded when the buffersize reachs a special value. I find the buffersize*framerate is about 64. Can i low this value?

    Would you mind reposting this question over on the Flash Professional forums?  This forum is primarily for end users, the Pro forums will get you in touch with a wider developer audience.
    Thanks,

    Hi Mithun,
    Here are a few points related to performance issue. These might be helpful.
    The performance of a report is related to:
    External factors:
    1. The amount of time the database server takes to process the SQL query.
    ( Crystal Reports send the SQL query to the database, the database process it, and returns the data set to Crystal Reports. )
    2. Network traffics.
    3. Local computer processor speed.
    ( When Crystal Reports receives the data set, it generates a temp file to further filter the data when necessary, as well as to group, sort, process formulas, ... )
    4. The number of records returned
    ( If a SQL query returns a large number of records, it will take longer to format and display than if was returning a smaller data set.)
    Report design:
    1. Where is the Record Selection evaluated?
    Ensure your Record Selection Formula can be translated in SQL, so the data can be filter down on the server, otherwise the filtering will be done in a temp file on the local machine which will be much slower.
    They have many functions that cannot be translated in SQL because they may not have a standard SQL for it.
    For example, control structure like IF THEN ELSE cannot be translated into SQL. It will always be evaluated
    in Crystal Reports. But if you use an IF THEN ELSE on a parameter, it will convert the result of the condition to
    SQL, but as soon as uses database fileds in the conditions it will not be translated in SQL.
    2. How many subreports the report contains and in section section they are located.
    Minimise the number of subreports used, or avoid using subreports if possible because
    subreports are reports within a report, and if you have a subreport in a details section, and the report returns 100
    records, the subreport will be evaluated 100 times, so it will query the database 100 times. It is often the biggest
    factor why a report takes a long time to preview.
    3. How many records will be returned to the report.
    Large number of records will slow down the preview of the reports. Ensure you only returns the necessary data on the report, by creating a Record Selection Formula, or basing your report off a Stored Procedure, or a Command Object that only returns the desired data set.
    4. Do you use the special field "Page N of M", or "TotalPageCount"
    When the special field "Page N of M" or "TotalPageCount" is used on a report, it will have to generate each page
    of the report before it displays the first page, therfore it will take more time to display the first page of the report.
    If you want to improve the speed of a report, remove the special field "Page N of M" or "Total Page Count" or formula that uses the function "TotalPageCount". If those aren't use when you view a report it only format the page requested. It won't format the whole report.
    5. Link tables on indexed fields whenever possible.
    6. Remove unused tables, unused formulas, unused running totals from the report.
    7. Suppress unnecessary sections.
    8. For summaries, use conditional formulas instead of running totals when possible.
    9. Whenever possible, limit records through selection, not suppression.
    10. Use SQL expressions to convert fields to be used in record selection instead of using formula functions.
    For example, if you need to concatenate 2 fields together, instead of doing it in a formula, you can create a SQL Expression Field. It will concatenate the fields on the database server, instead of doing in Crystal Reports.
    SQL Expression Fields are added to the SELECT clause of the SQL Query send to the database.
    11. Using one command as the datasource can be faster if you returns only the desired data set. It can be faster if the SQL query written only return the desired data.
    12. Perform grouping on server
    This is only relevant if you only need to return the summary to your report but not the details. It will be faster as less data will be returned to the reports.

    Shweta

  • How to use the selection profile and status profile for production order?

    Hi expert,
       I want to know how to use the selection profile and status profile for production order. what's the usage for these two selection profile and status profile ?
      Please help me.
      thanks in advance.
      george.shi

    Hi George,
    There are are two types of statuses.One is system status and second one is user status.These statuses will tell us current situation of an order.
    We can't change system statuses.But we can create our own statuses through status profile.With this profile we can control user statuses.
    In this status profile,
    1.We define the sequence in which user statuses can be activated,
    2.We define initial statuses
    3. Allow or prohibit certain business transactions.
    Selection profiles are used to select the objects (say production orders) with different status combinations.We assign status profiles to selection profiles in BS42 T-Code.

  • How to deploy the Oracle Forms and Reports 10g in Web?

    Currently I am working in Oracle forms & Reports conversion project (6i to 10g).
    As of now 6i forms working as a standalone application. After migrated it to 10g, I need to deploy the forms and reports in web.
    Any one know how to deploy the Oracle forms and Reports in web?
    Please help me out. Thanks in advance.
    Vimal

    Hello Frank,
    for development, you need to install Oracle Developer
    Suite 10g. This includes Forms and Reports.this topic interests me too, because I've downloaded Developer Suite and Database (both for 10g) from Oracle website, installed them, but I couldn't connect to a database.
    What should be done for me to create a database link and be able to connect locally, in my personal Desktop computer? (Not to a server)
    Once it was told me here that I should download 10g Database - I did it, and installed it, but it didn't work. Later, some of my job partners said I should install them in a sequence - that is, 1st the Developer, and 2nd the Database. But it has failed too. And I don't know how to configure a database connection.
    Best regards,

  • How to output the digital clock and synchronization signal from the NI USB-6211

    Hello,
    I need to connect the NI USB-6211 to control a digital to analog convertor chip (AD5541). However, this chip requires three input signals :1) Clock input, 2) Logic input or a synchronization signal  and 3) Signal Serial Data input (CS, SCLK, DIN).
    how to output the digital clock and the synchronization signal from the NI USB-6211?

    Hi SaberSaber,
    You should be able to use the counters to generate a pulse train that could be used for clock and synch purposes.  
    Hope this helps.  Let us know if you have more questions.

    Hello,
    Exactly which USB device are you referring to? Is the device a NI product?
    The Product ID for National Instruments DAQPad-6020E is 0x12C0. The USB vendor ID is 0x3923. This is a 16-bit hexadecimal number(1093) (that is decimal 4243).
