How to get each thread in the threadpool

Hi,everyone.I'm now learning java.util.concurrent package and I have two questions about the threadpool.
1) How to get each thread in the threadpool;
2) How to get each thread's data in the threadpool and dispaly them onto GUI;
e.g :
There are 5 threads in the threadpool(ThreadPoolExecutor) and I have 100 tasks(Runnable or Callable),every task scans a directory(every task scans a different directory),how can I display the "real-time" count of the files in the directory which the current 5 threads in the threadpool scan onto the ListView Items in the GUI?

Finally you notify the monitor when the execution has completed.

    I am using oracle 10g.
    In the process of getting each number from the parm '(25,23,35,1)' , I also need the position of the number
    say 25 is at 1 position.
    23 is at 2
    35 is at 3
    1 is at 4.
    the reason I need that is when I build seperate select for each value, I need to add the query number at the end of the select query.
    Please see the code I wrote for it, But the select query is having error:-
    BEGIN
    IF(pi_flag_codes IS NOT NULL) THEN
    SELECT length(V_CNT) - length(replace(V_CNT,',','')) FROM+ ----> the compiler gives an error for this select query : PLS-00428:
    *(SELECT '(25,23,35,1)' V_CNT  FROM dual);*
    DBMS_OUTPUT.PUT_LINE(V_CNT);
    -- V_CNT := 3;
    FOR L_CNT IN 0..V_CNT LOOP
    if L_CNT=0 then
    V_S_POS:=1;
    V_E_POS:=instr(pi_flag_codes, ',', 1, 1)-1;
    else
    V_S_POS:=instr(pi_flag_codes,',',1,L_CNT)+1;
    V_E_POS:=instr(pi_flag_codes, ',', 1, L_CNT+1)-V_S_POS;
    end if;
    if L_CNT=V_CNT then
    V_ID:=TO_NUMBER(substr(pi_flag_codes,V_S_POS));
    else
    V_ID:=TO_NUMBER(substr(pi_flag_codes,V_S_POS,V_E_POS));

    Pls help me with fetching each value to build the where cond of the select query along with the query number.

  • "there were not enough threads in the threadpool object to complete the operation" exception

    Post Author: crystalmatrix
    CA Forum: .NET
    I have a WinForm application using a Crystal Report Viewer control that in turn connects to a CR web service to display report. The client side application runs on WinXP SP1 with .Net framework 1.1, and the server is Win2k with ASP.Net 1.1. I am using CR XI out of the box.
    Users would periodically get "there were not enough threads in the threadpool object to complete the operation." exception when trying to launch the report viewer connected to the web service. The web service is a standard example implementation derived from CrystalDecisions.Web.Services.ReportServiceBase class. The problem usually happens when the user tries to open multiple report viewer forms, but once they get the error, it would continue to happen even after the user shuts down all viewer forms and then tries to launch a new one.
    There are some posts on the web regarding multiple asynchronous HttpWebRequest draining threadpool when running simultaneously and each one taking a long time to complete. However, our reports all run pretty quickly and results are usually returned before the next report starts to run. So my question is: does Crystal Report Viewer control has a problem with web service in that it may hold the HttpWebRequest thread even after the report is returned, or any other problem that may prevents the asynchronous thread being released back to the Threadpool? Anyone has experienced similar problems and has a workaround?
    Any advice is appreciated.

    What do you mean with "it doesn't work"? Do you get a compiler error? Do you get an exception at runtime? What's the error message?

  • How to get Open Balance for the year and Total Ending Balance?

    For a given account, how to get Open Balance for the year (Cumulative Ending Balance) and Total Ending Balance (Cumulative Ending Balance)?
    Is there any function module available? or should I read from some tables? Please advice.

    Hello Paul,
    You could try calling one of the following BAPIs - see which one meets your requirement. They are documented well so shouldn't be a problem finding out the correct one for your requirements.
    BAPI_GL_GETGLACCBALANCE      
    BAPI_GL_GETGLACCCURRENTBALANCE
    BAPI_GL_ACC_GETBALANCE      
    BAPI_GL_ACC_GETCURRENTBALANCE
    BAPI_GL_ACC_GETPERIODBALANCES
    BAPI_COND_VAL_DECRE_BALANCES
    You might have to put in some of your own logic after the BAPI call to get what you want.
    Hope this helps,
    Cheers,
    Sougata.
    p.s. Also look at FM FAGL_GET_ACCOUNT_BALANCE

    how to process each records in the derived table which i created using  cte table using sql server

    Ideally you would be doing a set based processing rather than traversing row by row as thats more efficient. To answer it specific to your scenario we may need more info. Can you explain with some sample data your exact requirement?

  • How to get a question in the course placed anywhere in the course and does not appear in the quiz result or total number of questions. Pretest would work except it can't go anywhere in the course (at least for me it can't)

    How to get a question in the course placed anywhere in the course and does not appear in the quiz result or total number of questions. Pretest would work except it can't go anywhere in the course (at least for me it can't)

    Use a normal question, and do not add the score to the total score. That will give you a correct score at the end. But the total number of questions, that system variable will still take into account all questions. You'll need a user variable, and calculate its value by subtracting 1 from the system variable cpQuizInfoTotalQuestionsPerProject. Same for the progress indicator if you want to show it?
    Customized Progress Indicator - Captivate blog
    If you want to allow Review, you'll have to tweak as well. You didn't specify the version, and all those questions I now mentioned.
    And my approach, since you talk about only one question: create a custom question, because you'll have total control then.

    how to get boot camp in the emac

    Furthermore, eMacs can only emulate the Windows environment, whereas Intel CPU Macs including the iMac you have running 10.6.8 can virtualize Windows.  Emulation is a poor man's solution, because software is used to replace functions that normally take place with hardware.  You can use the iMac to do any data conversion before it gets sent back to the eMac over a network.  See my FAQ* regarding Windows on the Mac:

  • HT4889 Replacing System hard drive with a new one. How to get everything over to the new boot drive?

    Replacing System hard drive with a new one. How to get everything over to the new boot drive? Should I use Carbon Copy or does apple have a better untility to do this?
    I can't get my current system drive (OSX 10.8.3) to start on the first try. I always have to shut down and restart again to finally see the Apple logo.
    Have used disc utility to repair the disc and permissions several times and that works. The next time I boot up, it works fine and I get the apple logo, but then the second time I boot up, it's back to the blank screen again and it only boots after the second try.  I have tried this repair three different times now always with the same result. Works right the first try (after the repair) then from the second time on it doesn't work. I just get the white screen until I reboot a second time.
    Thinking I should change drives but what's the easist and best way to move everything over to the new drive so it will boot correctly with all my data on it. This is the system drive for a Pro Tools 10HD setup. MacPro 3,1 with 16 gigs ram and OSX10.8.3 on it.
    Thanks for any help!

    If you have a time machine back up of your current drive you can do this
    Shut down your computer, install the new drive. While the computer is off plug in the external hard drive that you have your time machine back up on. Hold Option key while the computer turnes on, let go of the option key once you get a grey screen. Shortly after you'll see  a list of bootable drives, select the one that has your time machine back up on it and boot into that drive.
    From there go into disk utility, format your new drive too, osx extended journaled ( I think, double check that, its been awhile since ive had to do this), hit format
    Exit disk utility and then you can use time machine to copy all your exisit data to the new hhd and then your pretty much done.
    There is also a program called Carbon Cloner that will do esentially the same thing however I've never uesed it.
