Regarding performace issue

hi,
i want to retrieve the no. of records available for 6 months period. if i am writing single query to retrieve data for 6 months, it's getting timed out in jsp. i am using java and jsp for this.
so using function call, i want to retrieve the no. of records available for weekly or monthly and want to get the total no. of records available for 6 months.
how to split the date range into smaller subset in java?
and not even a single day should be left in between?
any build-in function is available for this?
how to do this?
it's urgent.. can anyone help me?
thanks,
Sri

Fixing performance issue at the end point may not provide much improvement.

    i am working on these from 2 days
    but i am not getting any performace.so please reply me
    what is the solution to increase the number of records per second dump into
    Oracle int this scenario.
    Thanking you

    Hi,
    what is the solution to increase the number of records per second dump intoOracle
    With the right configuration, I've been able to insert over 300,000 rows per second.
    First, optimize your inserts:
    http://www.dba-oracle.com/t_optimize_insert_sql_performance.htm
    Next, look at running parallel insert threads, using multiple freelists or ASSM:
    http://www.dba-oracle.com/t_parallel_dml_updates_inserts.htm
    Finally, using SSD will speed-up optimized inserts:

  • Regarding performence issue of  Z-Report

    Hello experts
    While i am analyzing my Z-report with ST-05 transaction, the duration of Fetch column showing in pink color for analysing that i am selected and clik on explain above nothing is coming. What is the meaning of this and how to avoid this. Is it really making down my
    Z-report down . Please kindly advise me.
    with regards
    Sridharmurali.

    1) Yellow color means normal
    2) Dark yellow colour means not bad.
    3) Pink or Red colour means SQL having performace issue.
    pure nonsense !!!
    Light and dark yellow change if the statements changes no other meaning
    Red color means that operation needs longer than 100ms (or other limit), also no meaning since it depends on the number of records which are read. Anyway it is starting point.
    The Explain is  only available for the OPEN/PREPARE operation (other line) no for the FETCH.
    Anyway, I would not recommend the trace list but the summary by SQL statements, see here

  • REgarding licensing issues involvng 'Computername' and the use of UpperCase4 vs Lowercase Letters

    Does any one know if it would cause problems for the Office 365 software license to be displayed as licensed to an ALL CAPS name like 'MY-FAVORITE-PC' but the computer itself shows the computer name to be 'my-favorite-pc"?
    If it does, which one should I change?  A couple of people here have had this same problem (which usually occurs when they change to using a different PC for their account) I have to Deactivate their Old PC namer and then install the licnse to
    their New OC using whatever name it has.
    On more than one system, this has resulted in various odd "failure to contact Microsoft server" issues when activating.  The problem continues for 7 days and then their copy of Office starts showing reed warning bards and eventually gets totally
    unusable.
    However, if I uninstall the office, deactivate the license, and reinstall it once again, it install just fine and acts ok but invariably at some point, the same thing occurs.
    On one of them I noticed the difference in the case of the letters used in the computer name and the license name.  On others I am wondering about various software add ins for Outlook or some other 3rd part application causing the problem.  Whatever
    it is, it gets extremely annoying.  Officer 365 apparently must run an activation sequence almost constantly while Office 2010 (and I presume 2013) ran it once and were done with it.
    Searching Google I have found too many  possible reasons along with a lot of people who have had the same problems but no one seems to have the 100% solution.   This has only started happening since we switched to Office 365 and only
    seems to occur on systems that are changed out to different ones with the same User's 365 Account which is in good standing  and has 5 available licenses of which only one is in use.
    In the case of the caps vs lowercase I also wonder if changing the name to CAPS on their PC would create additional problems on its own?

    Hi Questorfla,
    For the Office 365 software license issue, I recommend you can post in dedicated Office 365 Forum to get a better response:
    http://community.office365.com/en-us/f/148.aspx
    If there is anything else regarding this issue, please feel free to post back.

  • Regarding Consignment Issue

    Hi Friends,
             I have a question regarding consignment issue. During the consignment fill up I have entered a material (machine) that is configurable and also assigned a serial number to it. Now when I try to create an order (consignment issue) and enter the corresponding serial number tied up to the machine in Consignment fillup, the system is taking just the higher level item of the BOM. The BOM is not getting exploded in the order. Can anyone please suggest where I can control. Any help is greatly appreciated. Thanks in advance.
    Sunny.

    Hi
    I don't think it will b exploded in Consignment Issue as it has already exploded in Consignment fill up. Consignment issue means what selling the stock which is at consignee's place so it dose not have to b exploded. u carr on like that and see what is the flow if it is ok then go on otherwise u let me know the problem.
    Thanks

  • Regarding Performance Issue in MI Application

    Hii All,
    We have made a SmartSync MI Application.Everything thing is working fine.But the scenario is this that when we try to navigate through the application from one page to another ,for example if i click on one link to get details corresponding to that link(i.e) we are retreiving the data from the local database, but this is taking a lot of time and according to our buisness need we have to reduce this time to fetch the data.
    Can anyone help me regarding this issue what can be done either in coding part, what parameters & standards to follow to improve the performance.
    Thanks,
    Devendra Phate

    hello deven,
    if you are only focusing on your application's performance
    on the aspect of usability i.e. less waiting time, fast
    response UI, i would personally suggest you to use AJAX.
    put some processing part on the browser side and making
    data retrieval from MI asynchronous... this way, your user
    don't have to wait for all data to be presented, but rather
    could work on the data presented in pieces (i.e. asynchronously).
    anyway try googling for AJAX...
    regards

    My iphone plus is bending, what does Apple offer regarding this issue?
    I am trying to get to contact with Apple Customer Care, but not clear to me how to do it beside this channel of communication. I bought the phone from kosovar carrier which is under Slovenian ownership. This means that the original warranty comes from Slovenia, bit complicated but still I would like to get an urgent answer how to proceed with this issue, thanks

    Maybe i should have only asked if anyone is aware on apple's policy
    regarding bending. I took the point that this seems not a proper forum to
    pose Q's to apple thanks to both

    Here is my concerns and issue.
    For the all above all routines i am referring BI0/AFIGL_O1400
    DSO and finally loading to the Same DSO(BI0/AFIGL_O1400
    The worried part is my DSO  0FIGL_O1400 is currecnly having nearly 60 Lacks records and MM cube is having nearly 55 requests which are required to update to the Above DSO for PO related PO value and Invoice amount.
    The big issue here is while uploading data from MM cube to DSO say for example if the request is having  25,000 records from this  nearly 500-600 records will be updated to DSO.
    But here it is taking huge time ( nearly 3 days for request ) for updating  these records , like this i have to pull 50 more requests from Cube to DSO as per the requirement.
    Please note as of now i haven't created any indexes on DSO to improve this loads.
    Please note am facing this issue in Production environment and need your help ASAP.
    Thanks & Regards,
    Srinivas Padugula

    Hi,
    If selecting data from 0FIGL_O14 is taking long time then you can create secondary indexes on DSO.
    0FIGL_O14 would be huge as data volume directly corresponds to data volume in BSEG.
    But for you requirement, I think what you can do is,
    1. create multiprovider on top of DSO and Cube and create Bex report to give you the fields requried from both the infoproviders, you can then use open hub or APD approach to keep the data in the staging table or direct update DSO and then load the data to the DSO
    2. Create secondary indexes on DSO so that fetching would be faster.
    3. Do the enhancment at R/3 level to fetch fields from MM during load of G/L

  • Regarding goods issue

    Dear GUrus,
    I am issuing raw material against a production order.
    the BOM for the finished material is
    to produce one qty of FG 30 KG of raw material is required
    and the raw material available in my store is only 10KG. and it still allows me to issue that 10kg of raw material against that production order.(I am doing this with movement type 261)
    Where as the requirement from my user is that the system should issue an error msg that there is deficit of raw material quantity.
    Please look into the matter adn throw some light as to how do i set this in the system.
    Thanks

    Hi Anand,
    Check with your user, if they are OK with this -
    Release of Production order is possible only if all components exist i.e. full qty. If they are OK with that, then go to OPJK for the plant - order type - business function (2) combination set Release Material indicator to 3.
    This will prevent the order being released due to shortage of component qty.
    Hope the above is helpful.
    Regards,
    Vivek

  • Regarding goods issue (reversal) against process order

    Dear friends,
    Recently i have noticed one strange thing in SAP.I have created one process order and against it i have done the confirmation.Now when i go to Transaction code mb1a and select movement type 262 (Goods Issue to process order-reversal) and give the storage location and in next screen i gave order number,material code and its qty.These material code is not maintained in the bom of order header material.And even in process order in material tab we haven't maintained this material.Also while doing the confirmation in goods movement we haven't maintained this material.Then also system allows me to do so.Which means material which i haven't issued against the process order, system is allowing me to do its reversal i.e (262).because of which system is creating the stock for that material, which is not correct.
    Can we control this behaviour of system.
    Thanking you guys in advance.

    Hi Jitendra,
    This is fact and there is no standard Control available for the same.Only thing you can do is put control over Movement type 262 or try it by implementing User Exit.
    I am not sure but you can use Enhancement CCOWB001 - Customer exit for modifying menu entries.
    Include is LXCOWBF01.

  • Contacting skype via email regarding payment issue

    I would like someone to contact me via email regarding the following issue:
    I received a notification my account with Skype has been canceled.  I surmise that for some reason or another Citibank has not been sending payment via electronic payment per my contract with SKYPE.
    I have contacted Citibank just now via email, sending then the following message.
    (please email me back with your contact phone numbers so I can resolve this unfortunate incident or issue which I have first heard about an hour ago via an email to me from SKYPE)
    Received this from your accounting operations.
    Something wrong here as the payments are suppose to be make automatically when they g3et near the ten dollar mark.
    I have not been following payment as it has been done automatically-and this is the first notification.
    How can this be?  This amount shown is very strange and very incredulous to be this high unless Citibank Guam Visa has been not paying the amounts when charged by SKYPE.
    Obviously if this is true, for about the past five or so months by my estimate this has been happening.
    What is perplexing is that the credit card is still good and ca not understand how it was’t paid.
    Could you send me the past 2012 payments so I can see what has been going on?
    I will send this on to Citibank as an inquiry.
    Anyway, I do not want to cancel my SKYPE account.
    Thank you.

    Hi there     Alan Sokoloff,
    Problem with your payment
    Unfortunately, your payment failed, but don’t worry, we didn’t deduct   any money from your card.

    Why was my payment refused?
    Reasons for your card payment failing can be:1. You entered the wrong   details. Make sure you have the correct details and try again. You didn't   have enough money on your card. Make sure you have enough money before you   try again. You might be using an anonymous proxy or proxy server to access   the internet, which we don't allow during the purchase process.
