Maximum number of rows before doing a commit

When updating a database table, is there a maximum number of rows you should update before doing a commit work?

It's hard to give a specific answer. There are generally more than one rollback area in an installation and the size for the one used by batch processes may change after a certain time of day when more batch updates are being run. It will also depend on the size of the record being updated. It may also depend on whether you are in the development systemm QA or production.
But I guess, I would start with a number like 5,000 or 10,000 and see what happens.
You might also see if you can do the entire update in the QA system and commit afer it's done. If you can do it there, you'll likely be OK in production. Or if it works there, you can commit a couple of extra times in production - just to be sure.
Bear in mind though, that if you commit and the job fails later, you have to either be able to back out the updates, or start updating at the point where the previous one failed.

  • Does ADF pivot table in JDeveloper 11.1.1.2.0 have a maximum number of rows

    Does ADF pivot table in JDeveloper 11.1.1.2.0 have a maximum number of rows that can be fetched from the database?

    mmurmeli,
    Seems then that you've identified how to allow more rows (increase the heap space) ;)
    Hard physical limits aside, there is a practical limit to how much information a single human mind can absorb.

    I am getting the below error.
    Maximum number of rows (65535) exceeded. Result is incomplete.
    Message no. BRAIN675
    We are on SAP GUI 7.X and Excel 2007
    Is there any setting that I have to change inorder for BEX analyzer to display all the 200,000 records.
    Also any memory setting for the result set to be changed ?
    Please let me know your thoughts
    Thanks
    Doodle

    Hi Doodle,
    The rows limit for Excel 2007 is 1 million so this is not the problem with row limitation. It seems like you have opened the pre-excel 2007 workbook in excel 2007, check your title bar if it says "Compatible Mode". This will limit you to old standard of 65K.
    May be what you can do is , save your file using save as option and try running the workbook.
    Your new file extension will be .xlsx

  • BEx Variable Input Help (F4) Maximum Number of Rows

    Hi Experts,
    We using Bex 3.x version. Now, the user is asking to change the maximum number of rows (by default 500, for my case) to 1000. (While executing the workbook, on the variable pop-up screen where we can search for input help (F4) values). For surely, there is some global setting needs to be corrected but not sure. I have checked in T-code: SPRO and some of the threads but not get the apt solution.
    Could you please share us your inputs/experiences as how can we increase maximum number of rows in the input help.
    Many thanks in advance!!!
    Best Regards

    Hello Venkat,
    Is there is a way to setup that, you will find into this KBA Article (SAP Note):

  • What is the maximum number of row for a table control in LabWindows/CVI ?

    I use LabWindows CVI 8.5.1 (MMI first developped in version 6.0).
    In one of our many MMI, a table control contains a list of aircraft parameters.
    We can add as many parameters (row) as we want but over 40 000 we observe a crash of the LabWindows CVI runtime.
    Our client want to inscrease the number of parameters (row) up to 200 000 !!!
    So my questions are:
    What is the real maximum number of row for the table control ?
    Is this maximum number of row different on LabWindows 2010 version ?
    Or is there an other solution ?
    Thanks

    Greetings,
    Can you clarify what you mean by "crash"? Is there an error message thrown? Is it possible that you've consumed all of the available memory?

  • Maximum number of rows for an ALV

    Dear all,
    What is the maximum number of columns an ALV grid can handle .
    Best Regards,
    Manmohan.

    Hello Manmohan,
    As far as I know the total column size for a list screen is 1023 characters. ALV is actually making use of list screen instead of a dynpro. So as long as your total size of column if less than  1023, you can have as many columns as you want.
    For number of rows, I don't think there is limitation.

  • Is there a maximum number of rows in a sheet?

    Can anyone tell me if there is any limit to the number of rows per sheet in Numbers. (Excel now has a one million row limit.) May be there is some way to string sheets together so they act as one large sheet.

    JROA wrote:
    65536??? WHY???
    Because it's 16^4, which is an integer which may be coded with four bytes.
    The step beyond would be 16^6 or 16^8.
    But, given the slowness of Numbers, I am unable to work with tables of 10000 rows.
    From my point of view, it would be foolish to build tables with 65536 rows with the current app.

  • Maximum number of rows and columns in data form

    Hi,
    I wanted to know if there is a limitation to the number of rows and columns that can be displayed in a data form, in Hyperion planning 11.1.2.1 ?
    And what would be the most appropriate number of rows and columns to be included for optimum performance.
    Thanks.

    Hi,
    While its a fun fact to determine how much one can stuff into a web form, the reality is: how much can a user reasonably consume in a web form?
    And what would be the most appropriate number of rows and columns to be included for optimum performance
    You will find that the answer to this is by "what design makes a web form most usable?" And no, the users don't really know what they want from a design perspective, they see it in their head, but usually what they ask for is something that would look entirely different (huge).
    The next thing to think about is the use of member selection functions in the page axis. IDescendants(Entity) in a dropdown could cause issues just as easily as too many rows - and again make the drop down unusable for a user.
    If your question is a bit more technical, then consider this (somewhat oversimplified): Web forms are constructed by a process on the server. Objects are created based on the form's definition and used by the process that builds the form. The process uses Cartesian looping (lots of iterations) to construct the form cell by cell, starting at the top left and finishing up in the bottom right. If the form has a million cells on it, then the loop and all the code within it runs a million times. The capability of the server has a lot to do with how well it can handle this request, and how many it can handle at one time.
    The result of this is gobs of HTML and JavaScript. All of this has to be sent over a network to the requesting client. The client starts receiving the web page code and has to render it in the browser and run the JavaScript. The ability to do this is limited by the browser, the OS, and the hardware that the client is running on.
    And that's just rendering the page for use.
    Now it has to be interacted with on the client machine, and changes parsed, packaged, and sent back to the server.
    So the technical answer is, there can be many limitations to how many rows and columns a data form can have - none of which can truly be anticipated by anyone. This is why I put the part about usability first in this post.

  • Maximum number of rows export to excel from WebI

    Hello,
    I have a WebI Report in BO 4 SP6 which has 14 columns and 80,000 rows. I opened the report in WebI (Internet explorer) and clicked on the export icon but nothing happened. this report was being run for a month 201301.
    So I modified the same report with 1 week's data which is 4500 rows and when I exported it to excel 2007 and it worked.
    My questions are:
    1- how do I export 80,000 rows of data to excel?
    2- what servers/services are responsible for exporting data to excel?
    3- any other opinions that you can share which might help me.
    PS: I have not test this in rich client since rich client is not being used by users, Users only use WebI.
    Regards,
    samique

    After you click on export to excel. wait for some time for the pop up to come up.... Even after some time  if it doesn't come up and throw a timeout error "Missing sEntry parameter", then you can try by increasing the time limit. But I won't recommend this since, this is happening due to huge volume of data.
    Below thread might help you
    Error when exporting WebI to PDF
    If you export it using rich client, you can clearly see that the file size is too large.. It was 45 MB in my case. So I requested my user to put some filters and then do an export to excel.

  • What is the maximum number of rows in version 3.5.3

    I am using Numbers v3.5.3 in Yosemite.
    I need to copy/paste from a .txt file 1,085,300 lines of information.
    Numbers will only accept !65,000 lines.
    Is there a limit by default?  Can that be extended?
    Thank you.

    Hi Wayne - you have been very helpful; thank you.
    I work at a film / tv post production facility.  We use Outlook365 and the Sharepoint feature to share Word Docs and Excel Spreadsheets virtually.  I use the Excel functionality in Sharepoint so that we can track media we copy to our StorNext SAN volumes as well as the multiple LTFS and Tar Per Shot LTO5s we write for both our clients and as internal data backups.  Managing the media is beyond critical as TV and Feature studios require the utmost care of their OCF (original camera footage) and dailies / editorial media.
    Of the many toolsets we use to edit and color shows and feature films is the AutoDesk platform (think Flame, Inferno, Smoke).  The application toolset writes over 20TBs of data to our SAN volumes and the way it writes the data is unique to the application. If you tried to look at via a Mac Finder or Windows Explorer, the hex values in the filenames would not make sense. We cannot associate those hex names with actual human readable project names.
    One of my engineers used the AutoDesk app to spit out a 1 million line plus text file with human readable names of every project, file type and file path.
    What I am trying to do is suck all of that data into a spreadsheet that I can upload to Sharepoint (or paste directly into Sharepoint).  When I try to copy/paste on my Mac Mini directly into a Sharepoint page, both Safari and Firefox go into a spinning beach ball of death.  Time stops; photons of light are bent towards the event horizon; you get the picture.
    Since Numbers won't accept more than 65,000 lines, I need a way to get that data into a spreadsheet.
    I have downloaded LibreOffice and will give that a try. 
    Knowing what you do now, might you have any other suggestions?
    Thank you again.

  • Max number of rows?

    Hi,
    We have a new implementation of Enterprise X1 3.1 and are trying to determine what determines the maximum number of rows that can successfully be generated using Webi.  Is there a hard limit that Webi has (assuming the Universe max rows is deactivated)?
    Also, is there a limit for Live Office extractions into Excel?  What are the main drivers for this limit?
    Finally, all other factors being equal, are there different limits for the number of rows a query can return successfully in Webi vs Deski vs BEx?  How does the performance of these three tools compare to each other in terms of speed?
    Thanks!
    Darryl

    Thanks for your reply!  I also got a response back from SAP / BObj that I'll share:
    Q) We have a new implementation of Enterprise X1 3.1 and are trying to determine what determines the maximum number of rows that can successfully be generated using Webi. Is there a hard limit that Webi has (assuming the Universe max rows are deactivated)?
    => There is a limit to the number of pages Web Intelligence reports can have. This is because there are a maximum number of pages (per report) the server can process. This number depends on the paper size chosen. Generally, it is approximately 590000 inches vertically by 590000 inches horizontally. Therefore, if you choose a smaller paper size, you get more pages but may not see all the pages of the report.
    Resolution:
    To work around this behavior, you can either make each line smaller to get more records, or split your report into more than one report to see all your data.
    Q) Is there a limit for Live Office extractions into Excel? What are the main drivers for this limit?
    => By default its set to 512 rows and columns....however you can change this by modifying the Liveoffice_config.properties file...you can locate this file in /dswsbobje/lib/dsws_liveoffice_provider.jar.
    Q) Are there different limits for the number of rows a query can return successfully in Webi vs. Deski?
    => Although there is no official limit on the number of rows that can be handled by DeskI, it is really not meant to be used like a database, i.e. for returning millions of rows. The purpose of BusinessObjects reporting tools is to get useful information, which is not possible with millions of rows.
    => It has been observed that when the number of rows increases beyond 1.5 million approximately, it starts affecting the Desktop Intelligence performance. This behavior may vary from machine to machine depending upon the available resources and programs (processes) running in the background.
    => The limit is related to the number of rows those can actually be displayed in the report and not how many can be loaded into the data cube. All the rows get loaded in the cube however when it comes to rendering them in the report the problem may arise.
    Example: Report A returns 2 million rows into the cube however due to the report design there are only 200 rows in the actual report page and can be run successfully. Report B tries to render all 2 million rows into the actual report page and can fail.
    Workaround:
    Use filters in the report so that it will retrieve less number of rows and will also help to display useful data.
