Do We still need Secondary Indexes on the cubes with BWA being Primary

Hi Guru's
Could you please suggest us, do you think we still need secondary Indexes on the cubes with BWA being Primary

Compression: DB statistics and DB indexes for the InfoCubes are less relevant once you use the BI Accelerator. In the standard case, you could even completely forgo these processes. However, note the following aspects:
Compression is still necessary for inventory InfoCubes, for InfoCubes with a significant number of cancellation requests,
and for InfoCubes with a high number of partitions in the F-table. Note that compression requires DB statistics and DB
indexes (P-index).
DB statistics are necessary in particular for real-time InfoCubes and reading the most current data.
DB Indexes (index on the time dimension) are necessary in particular if the E fact table is not partitioned. Note also that you
need compressed and indexed InfoCubes with up-to-date statistics whenever you switch off the BI Accelerator index.
DB Indexes (index on the time dimension) are necessary in particular if the E fact table is not partitioned.
Note also that you need compressed and indexed InfoCubes with up-to-date statistics whenever you switch off the BI
Accelerator index.
Please refer to the below link for useful information on BIA.

  • Need to understand how the PGI date is being calculated

    Hi,
    Need to understand how the PGI date is being calculated.
    Does the PGI date get recalculated if the cusotme delivery date is changed.
    Thanks,
    Raki

    Hi,
    Thanks for the information and please let us know is there any calculation logic exist for that?
    I have changed delivery date in the sales order and based on that-
    - Transportation planning/material availability/loading/schedule line and confirmed quantity date was chaged.
    Is this the - GI date - Transist time= PGI?
    Thanks,

  • Transferring the Cube with activation of some Nav Attribute

    Hi , In Production system, I have a sales multicube which has data coming in from sales overview and sales history cube. Data is loaded from mARCH 2006 to Till date every day in 2 basic cubes "sales overview" and "sales history"
    Question 1:I need to now avtivate  "ship to party - postal code" which  is there in two basic cubes but not checked so I now select the check mark in nav attribute "ship to party - postal code" for both the cube in development system. and same in mULTICUBE should I Transport 2 basic Cubes, and Multicube and All effected Queries or just the query in which change is requested.  
    Question #2 : How to reload all the data which is right now there in Production, If I transport the cube with changes from DevLOPMENT to Production will the data be deleted in Production. All Data is feeding in Cube from ODS so Can I just Transport the cubes in Production and Use Update data to data target in ods. will the data be reloaded in cubes by doing that. Data loaded is delta so please let me know asap what will be best way to make the change and also save the data that is right now there in cubes in Production. since i have to transport it from dev no changes allowed in production.Hope you will reply back soon. Thanks
    alot
    seeraj

    Hardeep,
        You need to transport the Sales Overview cube, Slaes History, Multicube cube and modified Queries.
        when ever you make changes like Making Navigational there is no need to delete the data. you just do one transport.
    All the best.

  • The Cube with ID = Rate doesn't exist in the collection Error Message

    When doing a Full Optimization in the Rate cube I get a "The Cube with ID = Rate doesn't exist in the collection" error message. What is causing this error and how do I fix it?

    I have seen this error when reporting services was not properly configured. can you connect to http://servername/reports ?
    If not try to fix reporting services first, this solved the problem for me in the past.
    But usually in this case all the aplications are giving this error when modifying. Is this also the case in your appset?
    Does Apshell work when you modify the application there?

  • I no longer have an iphone.  Do I still need mobile me for the ipod touch?

    I no longer have an iphone.  Do I need mobileme for my ipod touch?

    You didn't need MobileMe for your iPhone either, per se. What was it about the service that caused you to sign up? Was it the "Find My iPhone" service? If so, that would still be perhaps useful for the iPod touch, though since the iPod has no GPS locations may be less accurate.
    If that doesn't answer your question, please post back with further information about your needs and what you're asking about.
    Regards.

  • Do I need to perform Process Index on the cube when measure groups has been processed with full individually?

    hi there, I am not sure if I need to perform process Index?  Do I have to do that after I process full on measure groups?
    thanks
    --Currently using Reporting Service 2000; Visual Studio .NET 2003; Visual Source Safe SSIS 2008 SSAS 2008, SVN --

    I did process update on all dimensions... after that, I did process full on each measure groups...
    In this case, do I need to process index on the whole cube? 
    Hi Cat_ca,
    ProcessFull - Simple to digest, applies all objects which means it discards the storage contents of the object and rebuilds them.
    ProcessIndexes - Applies to dimension, cube, measure group, and partition.
    Since you did process full on each measure groups, I don't think you need do a processindex, here are some links about process options on Analysis Services for your reference.

  • Do I still need GPS when A-GPS comes with Phone?

    Could somebody explain me whether I still need an external GPS module when using Nokia E71? E71 comes with A-GPS, which stands for assisted. What the heck it means. To me it sounds like "the GPS is not good, so it will need assitance from your provider".
    Nokia is still offering the Nokia Bluetooth GPS Module LD-4W as an accessory for E71. So this prompts me to ask whether I still need it. The LD-4W is not listed as Asssisted GPS. Does it mean it's better?
    I am confused with all that GPS.
    Thank you.

    Solved!
    Go to Solution.

    Great, thanks guys for explanation. Yes, I looked up, E71 has GPS with A-GPS. So it means it drains less battery and is faster to find location because the phone doesn't rely solely on the satellites but it gets information from towers faster.
    Does it mean, if I don't have data plan OR if there are no towers, the GPS still should be capable to do the job?
    Anyway, seems like a good idea to get LD-4W to save battery on the phone. The LD-4W can operate 11 hours on GPS only, no A-GPS. Can E71 come close in number of hours for GPS use? Anybody tried?
    An interesting thing would be whether E71 A-GPS can match the 11 hours of the LD-4W GPS unit. In the city the results would be different than on the countryside, I guess. Going on travel might make sense to get LD-4W. If staying only in city, it might make less value then? Hmm.
    I will give it a try and see how it works.

  • Do ORACLE support indexing on the columns with Hebrew Data

    Hello Forum,
    I was working on an assignment with schemas containing Hebrew Data.
    Can i create indexes on the columns containing Hebrew Language data?
    Thanks
    Priyank Jain

    Varchar2; is something difficult for me. Reason why is I need to make change in my application throughout to accept this design change.
    My need of Index on Hebrew Data:
    Basically I am going to implement a Full-Text Search environment. For full-text searching; I am having a plugin which implements Lucene Algorithm of Indexing.
    The Index writing will not be useful until the table is indexed and well-functional.
    "But note that standard indexes will be sorted according to binary order of Hebrew letters in Unicode."
    So does it means we are not going to index on actual data (Data in Hebrew)??
    Thanks

  • How to edit the cube with new fields without changing historical  in BI 7.0

    HI,
    I have requirment that need to edit cube with new fields and without changing historical data on it.
    Please some one can advise me abt the above scenario.
    Note:I am using BI7.0

    hi Krish,
    In BI 7.0,
    we cannot add a characteristic to an existing dimension if the data is not deleted from the cube.
    It can go to a new dimension and that will not change the existing structure of the cube tables, but will just add to it (as another dim table).  or use remodeling.
    for more details, please seach threads.....

    The only results I'm finding refer to sites that talk about jailbreaking iPhones.
    My only suggestion is to try restoring your iPhone, or to visit an AT&T store(assuming you're in the US) for a new SIM.

  • Why I still need to pay for the apps which I purchased when I downloaded in my 2nd iPad? For example the flashcards, I need to pay again for the additional games... Please help.

    I have paid for the additional games in my first iPad, when I download it again from purchased history, and execute it, it prompt me a request payment dialog. The truth is, I have paid it previously? Is it a normal for this kind off apps which is lite (free), and paid for upgrade would not have the previlage  for second device?

    Hi John,
    I agree with you, I downloaded it using the same apple id, and it is free even though for the first time downloading. We need to pay when we wanted to buy additional game/flash cards, but for my ipad2, when i select the one I have been purchased before for the additional cards, it prompt request payment... I am doubtful whether it will charge or not.....
