  • add script on boot linux machine

    - by user1546679
    I have one script to start a service on my ubuntu. I added it on boot machine using "# update-rc.d projeto defaults". But it still doesn't start with the boot machine. I think is because I am using other user to start the script "su - www-data -c ...". But I am not sure, because I run the update-rc.d command as root. When I execute the script from a terminal, it asks the password of the user www-data. Does anyone know what is happening? Thanks a lot! Felipe #!/bin/bash # /var/www/boinc/projeto/bin/start function action { su - www-data -c "/var/www/boinc/projeto/bin/$1" } case $1 in start|stop|status) action $1 ;; *) echo "ERRO: usar $0 (start|stop|status)" exit 1 ;; esac

  • how to add value to windows installer property table

    - by Felix
    According to MSDN installer sets ROOTDRIVE to the local drive that can be written to having the most free space. In my situation it is a slow USB drive that I use for nightly backup, but I would prefer to use my C drive for the install folder. But somehow I can't figure out how to set this property from command line or through PowerShell. I found that it is possible, but these instructions don't make any sense

  • Which are the RDBMS that minimize the server roundtrips? Which RDBMS are better (in this area) than

    - by user193655
    When the latency is high ("when pinging the server takes time") the server roundtrips make the difference. Now I don't want to focus on the roundtrips created in programming, but the roundtrips that occur "under the hood" in the DB engine, so the roundtrips that are 100% dependant on how the RDBMS is written itself. I have been told that FireBird has more roundtrips than MySQL. But this is the only information I know. I am currently supporting MS SQL but I'd like to change RDBMS (because I use Express Editions and in my scenario they are quite limiting from the performance point of view), so to make a wise choice I would like to include also this point into "my RDBMS comparison feature matrix" to understand which is the best RDBMS to choose as an alternative to MS SQL. So the bold sentence above would make me prefer MySQL to Firebird (for the roundtrips concept, not in general), but can anyone add informations? And MS SQL where is it located? Is someone able to "rank" the roundtrip performance of the main RDBMS, or at least: MS SQL, MySql, Postegresql, Firebird (I am not interested in Oracle since it is not free, and if I have to change I would change to a free RDBMS). Anyway MySql (as mentioned several times on stackoverflow) has a not clear future and a not 100% free license. So my final choice will probably dall on PostgreSQL or Firebird. Additional info: somehow you can answer my question by making a simple list like: MSSQL:3; MySQL:1; Firebird:2; Postgresql:2 (where 1 is good, 2 average, 3 bad). Of course if you can post some links where the roundtrips per RDBMSs are compared it would be great

  • How bad is opening and closing a SQL connection for several times? What is the exact effect?

    - by Eren
    For example, I need to fill lots of DataTables with SQLDataAdapter's Fill() method: DataAdapter1.Fill(DataTable1); DataAdapter2.Fill(DataTable2); DataAdapter3.Fill(DataTable3); DataAdapter4.Fill(DataTable4); DataAdapter5.Fill(DataTable5); .... .... Even all the dataadapter objects use the same SQLConnection, each Fill method will open and close the connection unless the connection state is already open before the method call. What I want to know is how does unnecessarily opening and closing SQLConnections affect the performance of the application. How much does it need to scale to see the bad effects of this problem (100,000s of concurrent users?). In a mid-size website (daily 50000 users) does it worth bothering and searching for all the Fill() calls, keeping them together in the code and opening the connection before any Fill() call and closing afterwards?

  • Nokogiri: add <tbody> after <table> elements as FireFox does

    - by wefwgeweg
    i have a problem: Firefox adds <tbody> whether it's there or not, after <table>. I have no problem with this. Nokogiri doesn't add it. I need Nokogiri to emulate Firefox's behavior. How can i add tbody after <table> elements to a given HTML page ? If tbody is already there, then move on to the next <table>....until all <tbody> tags are placed by Nokogiri. Thank you.

  • wxWidgets - Add items to sizer via DLL

    - by intl
    I have a GUI set up with wxWidgets (C++, MSVC) and part of the functionality is to add elements to the GUI via DLL's. Essentially, I would be passing in a sizer to the DLL which will in turn add the elements based on what is in the DLL. Could someone just point me in the right direction on how to get the DLL set up? I have looked, but don't see anything that's similar to what I'm looking for. The programming of the elements is fine with me, I just need to understand how to structure the DLL programming. Help appreciated.

  • TransactionScope and Transactions

    - by Mike
    In my C# code I am using TransactionScope because I was told not to rely that my sql programmers will always use transactions and we are responsible and yada yada. Having said that It looks like TransactionScope object Rolls back before the SqlTransaction? Is that possible and if so what is the correct methodology for wrapping a TransactionScope in a transaction. Here is the sql test CREATE PROC ThrowError AS BEGIN TRANSACTION --SqlTransaction SELECT 1/0 IF @@ERROR<> 0 BEGIN ROLLBACK TRANSACTION --SqlTransaction RETURN -1 END ELSE BEGIN COMMIT TRANSACTION --SqlTransaction RETURN 0 END go DECLARE @RESULT INT EXEC @RESULT = ThrowError SELECT @RESULT And if I run this I get just the divide by 0 and return -1 Call from the C# code I get an extra error message Divide by zero error encountered. Transaction count after EXECUTE indicates that a COMMIT or ROLLBACK TRANSACTION tatement is missing. Previous count = 1, current count = 0. If I give the sql transaction a name then Cannot roll back SqlTransaction. No transaction or savepoint of that name was found. Transaction count after EXECUTE indicates that a COMMIT or ROLLBACK TRANSACTION statement is missing. Previous count = 1, current count = 2. some times it seems the count goes up, until the app completely exits The c# is just using (TransactionScope scope = new TransactionScope()) { ... Execute Sql scope.Commit() }

  • Add HTML Id's to tags in .aspx file

    - by slandau
    So I'm writing an app that lets the user select a folder, it gets all the .aspx files in that folder, and lets the users check off which ones they want to add HTML ID's to. Then they click start, and this runs private void btnStart_Click(object sender, EventArgs e) { for (int i = 0; i < listFiles.CheckedItems.Count; i++) { } } It loops through all the selected file names. How do I open each of these .aspx files in the background, and go through them and add the id="thisItemId" attribute to each tag that's like a , , , , , etc....

  • Add Bookmark to IE automatically for new users on a computer

    - by Kyle Brandt
    When I set up a PC, I would like to be able to have it so when anyone logs into that PC from the domain a couple of IT bookmarks will be in IE. I read I can do this with a Domain-Level group policy, but unfortunately, with my current domain group policies have not gone well, so I have fear (Rather not get into this in this question). Can I do this at the PC level when I deploy a new computer? So any domain users who log into the PC will have these bookmarks added when their profile is created (no roaming profiles). These are XP machines, and the domain is run by 2003 controllers.

  • Perfectly reproducable select statement default ordering issue....

    - by Dave
    Hi, I've recently been chasing an issue with a client's db... solution found, but impossible to recreate. Essentially, we're doing a Select * from mytable where ArbitraryColumn = 75 Where MyTable has an Identity column, called 'MyIndentityColumn' - incremented by one in each insert. Naturally, and normally I would assume that the order returned would be the order in which they are inserted (bad assumption, but one which was forced onto me, through an inherited application - which has been patched). Essentially, I would like suggestions as to why the database, when restored to my local machine (same OS, same SQL server version - 200 sp3) same collation, and same backup instance restored on it, as a test DB on the client site. When I perform the above select, I get them in order of insert (i.e. identity column ordered ascending). On the client, it seems random (but the same 'random' order each time)... A few other points: I have the same collation on my test server as client Same DB backup restored to a test only I can access Same SQL server version and service pack Same OS Test DB is a new DB - new log and MDF... I have the problem 'solved' by adding an explicit order by clause but I want to undertand the cause of the issue, given the exact nature of my attempts to recreate it beuing futile, and perfectly recreatable on the client server... Thanks in advance, Dave

  • Add a listener inside or outside get method

    - by James P.
    I'm learning Swing and have composed an interface using a series of get methods to add components. Is it a good practise to add a Listener inside a get method as follows? I'd like to make things as decoupled as possible. private JButton getConnectButton() { if (connectButton == null) { connectButton = new JButton(); connectButton.setText("Connect"); connectButton.setSize(new Dimension(81, 16)); connectButton.setLocation(new Point(410, 5)); connectButton.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { // actionPerformed code goes here } }); } return connectButton; }

  • Firefox Add-On for closing multiple tabs except some

    - by Chris
    I'm looking for a Firefox addon, compatible with the latest version, which closes all tabs, except some which I can select. So, if I have 40 Open Tabs, and I want to keep only 3 open, this addon should be able to close the other 37. Such an addon is: https://addons.mozilla.org/en-US/firefox/addon/close-multiple-tabs/ Unfortunately, this version is not compatible with Firefox 13. Do you know an alternative?

  • Comparing two strings in excel, add value for common variables

    - by overtime
    I'm comparing two large datasets containing strings in excel. Column A contains the numbers 1-1,000,000. Column B contains 1,000,000 strings, neatly organized in the desired order. Column C contains 100,000 randomly organized strings, that have identical values somewhere in column B. Example: A B C D 1 String1 String642 2 String2 String11 3 String3 String8000 4 String4 String78 What I'd like to do is find duplicate values in columns B and C then output the Column A value that corresponds with the string in Column C into Column D. Desired Output: A B C D 1 String1 String642 642 2 String2 String11 11 3 String3 String8000 8000 4 String4 String78 78

    Basically I have a Segmented Controller on my NavBar right in the middle. What I want to be able to do is hide the Segmented Controller and add a title to the navigation bar. But with my code, the segmented controller is being hidden, but the title will not add, thus leaving a blank NavBar. This is my simple code in .h: IBOutlet UISegmentedControl *toggleDay; IBOutlet UINavigationBar *navBar; And this is my code in my .m: toggleDay.hidden = YES; navBar.topItem.title = @"Title"; Any help would be great thanks!

  • How to add "make install" target to simple Eclipse C project

    - by Jim Flood
    I have a simple Eclipse C project. Is there a way to add a "make install" target to the generated makefile? I can't seem to find the right search keywords to find any useful information in the doc or by googling (i.e. there is too much noise and no signal.) I tried creating a simple project using the autotools plug-in but without being able to find any useful doc or tutorial that starts from scratch with a single C source file, I couldn't even get the project to build. Edit: I'll take an answer based on using the autotools plug-in if I can get my project to build. I don't see how to add an include dir (-I) a link dir (-L) or additional link libs to a new Hello World autotools C project. Is there any simple autotools plug-in tutorial that covers this?

  • Does a Postgresql dump create sequences that start with - or after - the last key?

    - by bennylope
    I recently created a SQL dump of a database behind a Django project, and after cleaning the SQL up a little bit was able to restore the DB and all of the data. The problem was the sequences were all mucked up. I tried adding a new user and generated the Python error IntegrityError: duplicate key violates unique constraint. Naturally I figured my SQL dump didn't restart the sequence. But it did: DROP SEQUENCE "auth_user_id_seq" CASCADE; CREATE SEQUENCE "auth_user_id_seq" INCREMENT 1 START 446 MAXVALUE 9223372036854775807 MINVALUE 1 CACHE 1; ALTER TABLE "auth_user_id_seq" OWNER TO "db_user"; I figured out that a repeated attempt at creating a user (or any new row in any table with existing data and such a sequence) allowed for successful object/row creation. That solved the pressing problem. But given that the last user ID in that table was 446 - the same start value in the sequence creation above - it looks like Postgresql was simply trying to start creating rows with that key. Does the SQL dump provide the wrong start key by 1? Or should I invoke some other command to start sequences after the given start ID? Keenly curious.

  • Full-text search locks up database - error 0x8001010e

    - by Stewart May
    Hi We have a full-text catalog that is populated via a job every 15 minutes like so: ALTER FULLTEXT INDEX ON [dbo].[WorkItemLongTexts] START INCREMENTAL POPULATION We have encountered a problem where the database containing this catalog locks up. There are a couple of scenarios, we either see the job execute and the process hang with with a wait type of UNKNOWN TOKEN, or we see another process hang with a wait type of MSSEARCH. Once this happens the job continues to run but informs us that the request to start a full-text index population is ignored because a population is currently active. Looking in the full text log files we see the following error each time these problems occur: 2010-04-21 08:15:00.76 spid21s The full-text catalog health monitor reported a failure for full-text catalog "XXXFullTextCatalog" (5) in database "YYY" (14). Reason code: 0. Error: 0x8001010e(The application called an interface that was marshalled for a different thread.). The system will restart any in-progress population from the previous checkpoint. If this message occurs frequently, consult SQL Server Books Online for troubleshooting assistance. This is an informational message only. No user action is required."'' The only solution is to restart the SQL Server service and then the full text service. This is now occuring on a daily basis now so any help would be appreciated.

  • Cloning a VM to add a new MySQL Slave

    - by Ben Holness
    I am in the process of adding a new slave to a replicated mysql setup. All of the slave nodes are virtual machines. If I clone one of the nodes to a new VM, then start it with no networking, stop mysql, change the server-id in my.cnf to a new id and then restart mysql and networking, will it all work correctly, or will mysql get confused because it used to be a different server id?

    - by Magdy Roshdy
    I was have WSS 2.0 and then I upgraded to WSS 3.0 and the old instalation database was SQL 2000, now I have another SQL Server instance called:server_name\MICROSOFT##SSEE . After upgrade every thing works fine and our team started to use the portal and we sent lot of documents and make lot of activities on it. The problem started after installing Windows updates the website suddenly stopped and giving me an error "Cannot connect to the configuration database" If I tried to open SharePoint Products and Technologies Configuration Wizard it is gives me a strange error says: "An exception of type Microsoft.SharePoint.PostSetupConfiguration.PostSetupConfigurationTaskException was thrown. Additional exception information: SharePoint Products and Technologies cannot be configured. The current installation mode does not support SKU to SKU upgrades because there exists an older version of Windows SharePoint Services that must be upgraded first " At this post:http://stackoverflow.com/questions/114398/iis-error-cannot-connect-to-the-configuration-database/249494#249494 the guy of the second answer have the same problem and he suggested a solution but I don't understand well. I tried as he suggested to make the identity of the app pool of the SharePoint web site as "IWAM_server_name " after that the error changed as he said and I web site give me "Server Application Unavailable " and when checked the Event Viewer at the server I found that ASP.NET 2.0 give this exception: "Could not load file or assembly 'System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. Access is denied ." and I don't know how to solve this problem. I'm really want to make my web site working because our team really need these documents and its stuff. I hope I will find some one to help me.
