What kind if tables are suitable for partitioning?

What kind of tables are suitable for partitioning?
I have several tables in same schema. Each of them is bigger than 200MB. DML commands are executed continuously against these tables. After diagnosis, I know than the sequential read wait is the root cause. Should I partition each of them?

BTW sequential read wait has to do with index scans, not table scans. Table scan waits are reported as scattered reads, not sequential.

  • Which tables are suitable for advanced compression in R12.1.1 vision db

    I want to use advanced compression in our R12.1.1 test env and I want to know which R12 tables are suitable for that?(I want make a script for compressing our VISION DB automatically)
    for example, table like GL% and ... ?
    some table contain long/long raw data_type ,so if I compress all tables in a tablespace(like APPS_TS_TX_DATA) ,filter long/long raw table will became a time-cosuming job..
    thanks

    Hi,
    for example, table like GL% and ... ?I believe this is no direct answer to your question as this depends on the number/type of records you have in your tables, and this varies from one organization/environment to another. You could calculate the size of the tables and decide which tables need compression by yourself.
    some table contain long/long raw data_type ,so if I compress all tables in a tablespace(like APPS_TS_TX_DATA) ,filter long/long raw table will became a time-cosuming job..Please see if these links help.

  • What kind of certification is suitable for our product

    We have a J2EE product which focus on supply chain. Now I would like it to run on netweaver and exchange data with SAP (e.g. material master, purchasing doc) so that it can be seen as extenstion of SAP.
    What certification process is suitable in this case? Power by netweaver or Xapps cert?
    I looked at power by netweaver but it's merely deploying application on SAP J2EE application server and exporting some iview.
    For Xapps certification, it requires the combination of services from more than 1components whereas our application only need to communicate with SAP.
    Please help tell us the way to go.
    Thanks
    Giang

    Hi Giang,
    Your application can still qualify for a Packaged Composite Application (PCA) (The name xApp is reserved for SAP applications and PCA is an equivalent for 3rd-party developed xApps). For example, if you use one or more SAP composition tools such as, Composite Application Framework, Guided Procedure or Visual Composer to develop your PCA.
    I suggest that you apply for a PCA certification by using the <a href="http://www.sap.com/partners/howtopartner/application/">link</a> so that we can better help you.

  • What type of tables are stored in TVDIR ???

    Hi Experts,
                   I have created one custom table " ZEMPLOYEE ". I activated it succesfully without any type errors.But it is not found in this table TVDIR.
    What might be the reason ? <b>What type of tables are stored in TVDIR ???</b>
    Regards,
    V.Raghavender.

    Hi Raghava,
    TVDIR stores the tables and views which has <b>table maintainance generator</b>.
    We can create table maintainance generator using <b>sm30</b> TCODE.
    If you create table maintainance generator for your table then there will be an entry of your table in TVDIR.

  • What kind of costs are assessed and distributed

    Hi Gurus,
    Can anyone explain to me what kind of costs are usually assessed and what kind of costs are usually distributed?
    Thanks

    hi there,
    ok lets say you have a company and you have diff departments in there for say manufacturing, accounting, sales, marketing, HR and so on...and each are made cost centers since as you know each dept is a cost center where some or the other cost incurr on them
    and you will have expenditure on ur company right!
    lets say you have to pay electricity ,and rent for the building , and water bill, and postage and telegram expenses and things like that..
    each department might be using diff units of electricity for say manufactuting department might use the 70 % of the total bill and other depts use only 30% of the whole bill but in the electricity expense GL you will put down the 100 % bill
    since we have cost centers and this amt is goin to cost center attached on that gl so at later point they distibute the amt to other cost centers accordingly for internal auditing purpose ( to keep track of ) how much cost incurring in whihc department.
    hope this gives you some idea on what you are looking for. assign points if helpful

  • What kind of glass is used for the iPhone 6?

    I want to get a case before we upgrade to the iPhone 6.  Some of the cases we are looking at (Speck Mightyshell) do not come with screen protectors.  I was wondering what kind of glass is used for the iPhone 6 and if a screen protector is even necessary?

    The iPhone 6 currently uses Corning’s Gorilla Glass. There was some speculation that they would start using Sapphire glass but I guess they’re not ready yet. I have had my iPad 2 for years now and the glass is still perfectly fine. My new iPhone 6 uses a more developed version of the same glass. Will the glass break? Yes. Will the glass scratch? Yes, if you carry your phone in the same pocket as your car keys, the screen will scratch. It’s not impervious, just highly resistant.
    I do have a real life controlled experiment going on in the family. My wife and one son have their iPhone 6s in a case WITH a screen protector. Myself and my other son carry our iPhone 6s around without ANY protection whatsoever, no case and no screen protector. So far they all still look perfectly fine. We’ll se how this experiment turns out.

  • What kind of cert is needed for Client to MP/DP communication.

    Hi, 
    What kind of Certificate is needed for Client to DP/MP communication?   I know what the documentation says about setting up a Client cert and setting up auto enroll however, we are not able to setup auto enroll in a couple domains so we are trying
    to figure out how to get certs on these other machines.
    Will any cert listed in the personal store of the Client and the MP/DP work? 
    How does Config Manager pick the cert it needs to use for this on the CLient side and MP side?
    Thanks in advance.
    Thanks Lance

    We manually created a cert for a machine using the Config Manager Client template.   THis was the same template used to create the config manager client cert that we installed on the site system.
    So both the Config Manager server and Client have a cert created with this template (and therefore show the same template id).
    The client and config manager server have root certificate in the trusted root store from the same CA.
    in our ccmmessaging.log file on the client we get the following error.
    Certificate [Thumbprint ksdjfskfjdsfksjfskdfjskdjfskjfskdjfklsjdfslkfjdslkf] issued to 'machinename' doesn't have private key or caller doesn't have access to private key.
    in the certificates MMC it shows for the certificate with the above thumbprint..
    you have a private key that corresponds to this certificate.
    What are we missing?
    Thanks Lance

  • Which tables are used for Quality Efficiency calculation of OEE report ?

    Hello,
    We're confirming OEE report behavior.
    I'd like to know OEE report and ME table specification.
    Which tables are used for Quality Efficiency calculation of OEE report ?
    According to I know, the definition of Quality Efficiency is (complete qty) / (start qty).
    For this calculation, does OEE report just use qty_started and qty_completed of PRODUCTION_LOG table?
    If any other tables/columns/logic are implemented, your information is appreciated.

  • What compressor settings settings are best for 1080i  to output to DVD using DVD Studio pro?

    What compressor settings settings are best for 1080i  to output to DVD using DVD Studio pro? I used FCP 6, exported using Quick Time.

    DVDs are only SD. There was at one time HD-DVDs, which DVD SP and Compressor can make, but HD-DVDs will only play in Macs and, now obsolete HD-DVD players. HD-DVDs will not play back in standard DVD players or Blu-Ray players. If you want to make a "DVD will be played on DVD player for TV" disc, your only choice is SD.
    If you want HD video on a disc, then you want Blu-Ray. You will need a Blu-Ray burner (Apple does not make a Blu-Ray burner so you will have to buy a third-party Blu-Ray burner), Blu-Ray discs and software that will make a Blu-Ray disc. That could be the latest version of Compressor, or FCPX, or Toast, or Encore.
