  • Bulk Insert takes 4x as long on first operation of the day

    - by patrick
    I do Bulk Inserts into a table with about 14 million rows at fiver minute increments during a 7 hour period during the day. These inserts take somewhere between 9-14 secs. However, the first insert always takes about 40 secs. Anyone know what SQL Server 2005 would be doing differently on the first insert into a table for that day? From what I've read I should probably use the SqlBulkCopy class instead of just using a bulk insert in a stored procedure. Is that that the general consensus?

  • Slow retrieval of data in SQLITE takes a long using ContentProvider

    - by Arlyn
    I have an application in Android (running 4.0.3) that stores a lot of data in Table A. Table A resides in SQLite Database. I am using a ContentProvider as an abstraction layer above the database. Lots of data here means almost 80,000 records per month. Table A is structured like this: String SQL_CREATE_TABLE = "CREATE TABLE IF NOT EXISTS " + TABLE_A + " ( " + COLUMN_ID + " INTEGER PRIMARY KEY NOT NULL" + "," + COLUMN_GROUPNO + " INTEGER NOT NULL DEFAULT(0)" + "," + COLUMN_TIMESTAMP + " DATETIME UNIQUE NOT NULL" + "," + COLUMN_TAG + " TEXT" + "," + COLUMN_VALUE + " REAL NOT NULL" + "," + COLUMN_DEVICEID + " TEXT NOT NULL" + "," + COLUMN_NEW + " NUMERIC NOT NULL DEFAULT(1)" + " )"; Here is the index statement: String SQL_CREATE_INDEX_TIMESTAMP = "CREATE INDEX IF NOT EXISTS " + TABLE_A + "_" + COLUMN_TIMESTAMP + " ON " + TABLE_A + " (" + COLUMN_TIMESTAMP + ") "; I have defined the columns as well as the table name as String Constants. I am already experiencing significant slow down when retrieving this data from Table A. The problem is that when I retrieve data from this table, I first put it in an ArrayList and then I display it. Obviously, this is possibly the wrong way of doing things. I am trying to find a better way to approach this problem using a ContentProvider. But this is not the problem that bothers me. The problem is for some reason, it takes a lot longer to retrieve data from other tables which have only upto 12 records maximum. I see this delay increase as the number of records in Table A increase. This does not make any sense. I can understand the delay if I retrieve data from Table A, but why the delay in retrieving data from other tables. To clarify, I do not experience this delay if Table A is empty or has less than 3000 records. What could be the problem?

  • What happens when you click a button using WebRat under cucumber

    - by Peter Tillemans
    I am trying to login to a Java web application. The login page has the following html : <html> <head><title>Login Page</title></head> <body onload='document.f.j_username.focus();'> <h3>Login with Username and Password</h3> <form name='f' action='/ui/j_spring_security_check' method='POST'> <table> <tr><td>User:</td><td><input type='text' name='j_username' value=''></td></tr> <tr><td>Password:</td><td><input type='password' name='j_password'/></td></tr> <tr> <td><input type='checkbox' name='_spring_security_remember_me'/> </td> <td>Remember me on this computer.</td> </tr> <tr><td colspan='2'><input name="submit" type="submit"/></td></tr> <tr><td colspan='2'><input name="reset" type="reset"/></td></tr> </table> </form> </body> </html> I use the following script: Given /^I am logged in as (.*) with password (.*)$/ do | user, password | visit "http://localhost:8080/ui" click_link "Projects" puts "Response Body:" puts response.body assert_contain "User:" fill_in "j_username", :with => user fill_in "j_password", :with => password puts "Response Body:" puts response.body click_button puts "Response Body:" puts response.body end This gives the following in the log file : [INFO] Response Body: [INFO] <html><head><title>Login Page</title></head><body onload='document.f.j_username.focus();'> [INFO] <h3>Login with Username and Password</h3><form name='f' action='/ui/j_spring_security_check' method='POST'> [INFO] <table> [INFO] <tr><td>User:</td><td><input type='text' name='j_username' value=''></td></tr> [INFO] <tr><td>Password:</td><td><input type='password' name='j_password'/></td></tr> [INFO] <tr><td><input type='checkbox' name='_spring_security_remember_me'/></td><td>Remember me on this computer.</td></tr> [INFO] <tr><td colspan='2'><input name="submit" type="submit"/></td></tr> [INFO] <tr><td colspan='2'><input name="reset" type="reset"/></td></tr> [INFO] </table> [INFO] </form></body></html> [INFO] Response Body: [INFO] <html><head><title>Login Page</title></head><body onload='document.f.j_username.focus();'> [INFO] <h3>Login with Username and Password</h3><form name='f' action='/ui/j_spring_security_check' method='POST'> [INFO] <table> [INFO] <tr><td>User:</td><td><input type='text' name='j_username' value=''></td></tr> [INFO] <tr><td>Password:</td><td><input type='password' name='j_password'/></td></tr> [INFO] <tr><td><input type='checkbox' name='_spring_security_remember_me'/></td><td>Remember me on this computer.</td></tr> [INFO] <tr><td colspan='2'><input name="submit" type="submit"/></td></tr> [INFO] <tr><td colspan='2'><input name="reset" type="reset"/></td></tr> [INFO] </table> [INFO] </form></body></html> [INFO] Response Body: [INFO] [INFO] Given I am logged in as pti with password ptipti # features/step_definitions/authentication_tests.rb:2 So apparently the response.body disappeared after clicking the submit button.

I have no idea why the response.body is gone. I have no idea where I am. I speculated that I had to wait for the page request, but all documentation says that webrat nicely waits till all redirects, pageloads, etc are finished. (At least I think I read that). Besides I find no method to wait for the page in the webrat API. Can someone give some tips on how to proceed with debugging this?

  • Very long strings as primary keys in a database for caching

    - by Bill Zimmerman
    Hi, I am working on a web app that allows users to create dynamic PDF files based on what they enter into a form (it is not very structured data). The idea is that User 1 enters several words (arbitrary # of words, practically capped of course), for example: A B C D E There is no such string in the database, so I was thinking: Store this string as a primary key in a MySQL database (it could be maybe around 50-100k of text, but usually probably less than 200 words) Generate the PDF file, and create a link to it in the database When the next user requests A B C D E, then I can just serve the file instead of recreating it each time. (simple cache) The PDF is cpu intensive to generate, so I am trying to cache as much as I can... My questions are: Does anyone have any alternative ideas to my approach What will the database performance be like? Is there a better way to design the schema than using the input string as the primary key?

  • Counting keystrokes and clicks in vb.net

    - by Cyclone
    I'm trying to create an application similar to the site WhatPulse, which will generate an image with my clicks and keystrokes. WhatPulse only updates the image once every 24 hours, so I am going to make an application to keep track of that for me, only with realtime stats. How can I count total keystrokes (outside of the application itself) as well as total clicks, in vb.net? This is for personal use. Thanks for your help!

  • MySQL - how long to create an index?

    - by user293594
    Can anyone tell me how adding a key scales in MySQL? I have 500,000,000 rows in a database, trans, with columns i (INT UNSIGNED), j (INT UNSIGNED), nu (DOUBLE), A (DOUBLE). I try to index a column, e.g. ALTER TABLE trans ADD KEY idx_A (A); and I wait. For a table of 14,000,000 rows it took about 2 minutes to execute on my MacBook Pro, but for the whole half a billion, it's taking 15hrs and counting. Am I doing something wrong, or am I just being naive about how indexing a database scales with the number of rows?

  • Trigger jQueryUI datePicker on button click, send result to disabled input field

    - by Enrique
    Hi I've been searching for a way to do this, but could not find anything I want to have a: a disabled input text field, called #XX. This input will store the selected value from datepicker (as this input is disabled I won't be able to use this to trigger the datePicker) A button, besides #XX. When user clicks this button, datePicker will show. User will select the date, and this date will be assigned to disabled input #XX. I want this so user can't change manually -by typing crap- the selected date Also, should I validate if date was entered using #XX.val()? or is there a better way? Thanks

  • Strange: Planner takes decision with lower cost, but (very) query long runtime

Notice: Cost of the second query ist somewhat higher than for the first query. So the main question is: Why does the planner make the first decision, instead of the second? Also interesing: Via SET enable_seqscan TO false; i temp. disabled seq scans. Than the planner used indexes and hash joins, and the query still was slow. So the problem seems to be the hash join. Maybe someone can help in this confusing situation? thx, R.

  • sudo taking long time

    - by Sam
    On a Ubuntu 9 64bit Linux machine, sudo takes longer time to start. "sudo echo hi" takes 2-3 minutes. strace on sudo tells poll("/etc/pam.d/system-auth", POLLIN) timesout after 5 seconds and there are multiple calls(may be a loop) to same system call (which causes 2-3min delay). Any idea why sudo has to wait for /etc/pam.d/system-auth? Any tunable to make sudo to timeout faster? Thanks Samuel

  • Long text input from user and PDF generation

    - by Petteri Hietavirta
    I have built a web application that can be seen as an overcomplicated application form. There are bunch of text areas with a given character limit. After the form submission various things happen and one of them is PDF generation. The text is queried from the DB and inserted in the PDF template created in iReports. This works fine but the major pain is overflowing text. The maximum number of characters is set based on 'average' text. But sometimes people prefer to write with CAPS or add plenty of linefeeds to format their text. These then cause user's text to overflow the space given in PDF. Unfortunately the PDF document must look like a real application form so I cannot allow unlimited space. What kind of approaches you have used to tackle this? Clean/restrict user input? Calculate the space requirement of the text based on font metrics? Provide preview of the PDF? (too bad users are not allowed to change their input after submission...)

  • Click Once doesn't create StartMenu entry and Shortcut on Windows 7 x64

    - by MadBoy
    I've application that I deploy to share with ClickOnce so other users can install it and use it on their own machines. It worked fine till i noticed that when i install this app on my own machine (Windows 7 x 64) it doesn't add StartMenu (even thou it installs correctly and I have it in Control Panel / Programs). I didn't had that problem when my development machine was Windows XP. Application also deploys fine on other Windows XP computers. Also during installation (when i rerun setup) even thou I already have Net Framework 3.5 it always wants to install one (it starts that and terminates few seconds later - probably installer sees that it's already there). I can run application straigit from share just a bit of pain to do it. Are there some special settings I should do? Or some patches? I have Visual Studio 2008 and system with all optional updates installed. Application is written in C# and uses NET 3.5.

  • No middle-click scrolling in visual studio 2010?

    - by maxp
    Just as I started to assume this feature was ubiquitous(middle-clicking on a page, then scrolling speed/direction is relative to the distance of the pointer on the y-axis). I can't believe this hasn't been implemented into the text editor in vs2010, I used it all the time in 2005 and 2008. Has anyone managed to find a workaround or am I a minority user of this feature?
