Is there a case for creatiing more than on flat file sourece system in BI 7

Hello BI/BW Friends:
What are the Best practices / recommendations for the number of
flat file interfaces, Flat file source systems to be created in a BI/BW system.
I need to load 20 flat files into a BI 7.0 system.
Is there a best practice in this case?
Is there a case for more that one Flat File source systems being created to increase the speed or
parallel extraction of these flat files?
Am I creating any system contention by trying to extract all 20 of these files through the same flat file source system?
Any and all comments are appreciated.
Regarcs,
Joey G.

You don't need to create several Flatfile source systems for several files uploading, One would do
You can parallelize the loads with one file source , For performance point of view it's the same even you create several file sources or with one, the only thing you will have to concern is to fine tune the routines if any , load MD and then TD
If you have several file sources, You may get confusion and has to maintain them across the landscape.
Best practice would be upload all the files in application server and automate the loads thru process chains.

  • [Web] Is there a way to generate more than 1 CSS file?

    Obviously using model.appearance. with AddCustomCSS lets us generate a CSS file.
    I could create an AddPage file that uses maps nonCSS values into a pregenerated CSS file. The problem is that live_update doesn't handle these well.
    (if someone wants to write a more indepth look at doing stuff in Live Update, that would be fine with me, not to mention Matthew Campagna and John Beardsworth)
    Is there an alternative way, or are we restricted to one CSS file per model section? why do I need more than 1? iFrames. I don't want the same body values etc inside the iFrame HTML.

    Let me put it another way:
    What would I need to add to live_update.js to have nonCSS values force a refresh?

  • More than one flat files with same external table

    Is it possible to create external table in owb associated with more than one file ie to generate code like LOCATION ( FILE1,FILE2) in create table ddl.

    Hi,
    Yes, you can add multiple files by using the configuration of the external table, and create many instances of 'files'. Every 'file' you specify requires you to specify a location and a file name.
    For more details, please review chapter 5 of the user's guide (http://www.oracle.com/technology/documentation/warehouse.html), page 5-15.
    Hope this helps.

  • Is there a way to enable & configure Volume Discounts via the Product Import Spreadsheet? Is there a way to enable more than 2 Quantity Thresholds?

    Is there a way to enable & configure Volume Discounts via the Product Import Spreadsheet? Is there a way to enable more than 2 Quantity Thresholds?

    Hi Michael,
    You can set the thresholds via an import file. The easiest way to do this (and this goes for all importable data, webapps included, 301 redirects and so on) is this:
    1. go into the Admin and create a single item, in you case create a test product and set the thresholds
    2. export that data - in your case export the product list
    3. take a look at how the data looks like in the export file so you can get an idea of how the format should be like in the import file
    Unfortunately you cannot set more than 2 thresholds, that is not possible at the moment.
    Thanks,
    Mihai

  • Case structure with more than 200 cases, slower lab view app

    Problem Description :
    i am currently making a vi which compose of a simple case structures, a case structure with more than 200 cases, what i noticed is that the more i added cases the slower the labview reacts, it takes time for me to route wire on each of the cases.
    i dont know if there are any setting in the labview environment that i can increase the buffer size? i dont know... but its getting slow (only on the
    vi with more cases in a case structure)
    mytestautomation.com
    ...unleashed the power, explore and share ideas on power supply testing
    nissanskyline.org
    ...your alternative nissan skyline information site

    Can you clarify what you mean by "slow". Does it run more slowly or does it feel sluggish during editing?
    Could you attach the actual VI?
     Overall, I agree with the notion of local variable overuse. For example, you read the same local variable twice in the same case. Is there a need for this? Is there a chance that it varies between the two reads? Typically, you would place the terminal in front of the case structure and wire to all the locations where you need the value. This ensures that the data is consistent. Still, this should not cause any slowdown problem.
    (On a sidenote, the code in the upper left corner is inefficient. You convert the same data to lower case with each iteration, so you might want to place this before the loop and do it only once (well, if you are lucky, LabVIEW will fold the operation, but still....). Also your "index array" operation can be replaced by autoidenxing of the 2D array on the outer loop boundary.)
    LabVIEW Champion . Do more with less code and in less time .

  • How to increase the Heap space of Jdeveloper for about more than 512 MB?

    When starting JDeveloper, the application within JDeveloper is throwing the error message:
    "could not reserve enough space for object heap"
    and a windows popup with the following error message:
    "Unable to create an instance of the Java Virtual Machine Located at path: ..\..\jdk\jre\bin\client\jvm.dll "
    To resolve these issues, i know that adding the following in ide.conf , jdev.conf will help.
    AddVMOption -XX:MaxPermSize=512M
    AddVMOption -Xmx512M
    AddVMOption -Xms512M
    I have got 10 GB of RAM in my desktop machine and virtual memory of 15 GB (page size). I am not able to increse the heap space of Jdeveloper for about more than 512MB. This is really frustrating..I had to restart my jdevloper after 3 or 4 deployments.....Has anyone tried success in increasing the heap space in jdeveloper for about 2 GB?
    Regards
    Prasath.C

    Yes, i know that -XX:MaxPermSize has nothing to do with Heap Memory. I Just pasted all my configuration settings to know if some thing or the other has caused the issue.... After hearing few people who increased the heap space to more than 512m , i played with those settings again and figured out few things...Mine is Jdeveloper 11.1.1.4, 64 bit Windows 7 environment, 64 bit Java/ JDK.
    First, i was deceived by one suggestion in forum that, keeping max and min heap memory to same size always will yield in good performance...From that time on wards, i was always increasing both and was never able to move more than 512m..But this time, i kept the min memory as constand and kept on changing the max memory ..
    Jdev.conf
    AddVMOption -XX:MaxPermSize=512M
    AddVMOption -Xmx972M (I was never able to increase more than this size, though i have around 10GB RAM, if not Jdev doesnt startup)
    AddVMOption -Xms512M
    Ide.conf
    AddVMOption -Xmx2048M (here i was able to increase)
    AddVMOption -Xms512M
    But even then, i was not seeing my changed settings at the time of deployment...
    starting weblogic with Java version:
    java version "1.6.0_21"
    Java(TM) SE Runtime Environment (build 1.6.0_21-b51)
    Java HotSpot(TM) Client VM (build 17.0-b17, mixed mode)
    Starting WLS with line:
    C:\Oracle\MIDDLE~1\JDK160~1\bin\java -client -Xms512m -Xmx512m -XX:MaxPermSize=512m -Dweblogic.Name=DefaultServer ..........
    Then i changed again into
    setDomainEnv.cmd of my default domain
    set USER_MEM_ARGS=-Xms512m -Xmx2048m -XX:MaxPermSize=512m
    Then i stared my deployment...this time i could see a real boost in deployment...and my page was launched in a fraction of minute..

  • Is there a way to have more than one Query view in the same workbook?

    Is there a way to have more than one Query view in the same workbook?
    BEx allows us to insert Queries into workbooks, but not saved views.
    I can open a view in excel & then save it as a workbook....but after that there is no way to add another view to the same excel. If I open a new view, it opens in a new Excel.

    Hi

  • Maintenace view for fld more than 500 characters

    Ho do i create a maintenance view for fld more than 500 characters? i  need a maintenance view to maintain URL which is sometimes more than 500 chars.

    The way SAP solves this for webservices is via a hash.
    Once you have executed the service, the URL populates a mapping table and generates a unique hash value for it.
    Via this hash, you can assign it to authorization fields and use it in your coding where the fields have limitations.
    As a consequence this causes some confusion if you dont use F4, but it does work.

    My macbook fell off the couch and now everything on the display is double and slightly transparent. Is there a fix for this other than getting it replaced?

    Only an Apple Store or an authorized Apple Service Provider can determine if a repair is economically justifiable. It may be as simple as a dislodged display cable.
