How to manage when there are huge files in the batch program?

Hi all
There are huge files in my lot, and when I run the batch, the performance was very poor, then, how I divide it into several small batches to improve performance?

The solution below will work for single batch processing thread. With these lines, I was able to download 300 K Recoreds in ciustom table in 7 min.

int i = 0;
Read all the records in the input file
While (not null (record = {readRecord()))}

i ++ ;
If (I % 500 == 0) {}

((FrameworkSession) SessionHolder.getSession ()) .getHibernateSession () .flush ();
((FrameworkSession) SessionHolder.getSession ()) .getHibernateSession () .clear ();
}

Process record
} / / End then that

    Soham,

    I think you just create this LOV page by simply moving the VO, right?

    You can select the box to tick 'Include no. Selection' in your VO, and see if that helps?

    See you soon

  • Disable the generation of report when there are no returned by the query

    I would like to write a preliminary report trigger that disables reports generation when my main query in my data model will return no data. If possible, I would like to reuse the same query in the data model from the writing of a motion to double again.

    Thank you all

    Create a view for the main request. In this case, you just have to do it in the front trigger of the report:

    select count(*)
    into my_var
    from my_view
    where ...;
    
    if my_var =  0 then
       return false;
    else
       return true;
    end if;
    

    In where clause you can use the same settings as in your main report query.

  • When I open the Task Manager and select "Show processes from all users" there are 2 files virus csrss.exe?

    original title: virus csrss.exe?

    I use Vista Home Premium.  When I open the Task Manager and select "Show processes from all users" there are 2 files csrss.exe.  I learned that this indicates that I was infected by a virus.  Is this the case?

    Hi Julie,.

    Did you the latest changes on the system?

    Csrss.exe is Client/Server Runtime Subsystem.  All the Microsoft system has file csrss.exe running in the Task Manager, but it is likely to be infected by others. If it uses a lot of time processor and extremely abnormal in activities in the Task Manager, you can run a scan of the system security.

    Vincent

    No out-of-the-box, but there are several workaround solutions if you want to continue an any of them:

    (1) use a view selector. A single report will be a pivot table with the column, the other will have the same report less column. Users can switch reports.

    (2) use a column selector. The two choices would be this column or an empty space. If white is chosen (because the user has no values), the column "will disappear" according to the report.

    (3) guided use NAV. This method involves the intervention of the user. Build a small report using the single column and put a filter "is not equal to" 0. Because there is only a single column, so all lines are 0, the report returns no rows.

    Use this report in the properties of guided navigation from one section of the dashboard. Assign to this "If the report returns lines" and put the report that contains the column in this section. Now add another article on your table edge and in the properties of guided navigation of this section, set on "If the report will return no rows" and it points to the small report as well. In this section, put a second version of your report without the column in it.

    When the column contains all zeros, the second section with column will not display in it; the first section is not displayed. When at least a line contains a value not zero, the first section is displayed with the column, and the second part will not be.

  • When the Admin sign on the office comes to the top, but after that the computer does not respond when the user tries to do anything. There are actually turns off the computer with the power button.

    Original title: user profile

    My administrator user profile does not work properly, but I have a user profile that has activated the parental control that worked well for about a year and yesterday when this user logs on the desktop comes up, but after that the computer does not respond when that user tries to do anything. There are actually turns off the computer with the power button.  I ran a virus scan and spyware scan in my user admin profile and he has not found anything.  I don't know what to check.

    Hello rhunter15,

    There may be a program to interfere with Parental controls so that we can try a few things to see if we can determine the application or program that is causing problems.

    First of all, we run System File Checker to see if you have a corrupt file system.

    • Click Start
    • Click on all programs
    • Click Accessories, and then right-click on the command prompt.
    • Select the Security tab and choose "Run as Administrator"
    • Click on command prompt
    • Type SFC/scannow.

    It will scan and repair any damaged operating system files.

    To determine if there is a program because of a conflict, we recommend that you perform a "clean boot" of the computer. A clean boot is designed to disable programs and services in the background as much as possible. This helps determine which service or program can be the cause of the problem.  For more information about how to perform a clean boot for troubleshooting, click the number below to view the article in the Microsoft Knowledge Base.

    KB 929135 - how to solve a problem of performaing a clean boot in Windows Vista.
    http://support.Microsoft.com/kb/929135

    Once you have finished the clean boot, check again and see if you get the error of parental control.

    If please post again and let us know if that helped pinpoint the problem or if you still need help.

    Thank you

    Packer of creative cloud in creating a package that I can install do not.  He goes through the motions, download all updates, create setup file, but it does not work despite the fact that there are no errors in the log files

    After hitting my head against the desk to repeatedly create packages, try on different computers I have finally found a solution.

    These packages have been copied on an external drive, if I try and install from the external drive, which is a common practice, it fails.

    If I then copy this file pkg from the outside, to the computer I install, then run it, it will to and moved very well.

    That is mind-boggling stupid, because it's rare that you have to copy the file into any computer, it is less always installed off the coast of externally, and many people in the company are pushing on the network and the management of the suites so there is a serious problem in Adobe package manager if this is the case where it cannot manage the Middle installed offshore.
