  • Java process eating CPU; Why?

    - by Camran
    I have a Linux server which I have installed Java on. Sometimes, and only sometimes when a large nr of visitors visit my website, the site hangs. When I open the terminal and enter the "top" command to see whats going on, I can see that "Java" process is eating CPU! Like 400%. I have also tried ps aux command, and can see that the command is from usr/bin/java I have little experience in troubleshooting this kind of things, so I turn to you guys for help. I have a java container installed (Jetty) which I must have in order to use SOLR (search engine) which is integrated into my website. I can start and stop SOLR by: etc/init.d/solr stop But this didn't remove the java process from the "Top" command. Still java was eating 400% CPU. Is there other methods to restart java only? This has happened twice to me, and each time I have now restarted my entire servers and everithing is fine. If you need more input let me know! Thanks

  • Monit mail alert failed

    - by user119720
    I have configure our Monit to monitor some of the application in our linux box (httpd,mysqld,etc...).We can receive alerts when using gmail SMTP to send email through it but it failed when we are using our exchange SMTP. Here are the gmail configuration in the monitrc : set mailserver smtp.gmail.com port 587 # primary mailserver username "[email protected]" password "mypasswd" using tlsv1 with timeout 30 seconds and it failed when I changed it to this configuration : set mailserver outlook.automanage.net port 587 # primary mailserver username "[email protected]" password "mypasswd" using tlsv1 with timeout 30 seconds I can telnet my exchange server,so the exchange server is alive and can be connected. Did I miss anything here?Or do I need to need configure something in our exchange server?

  • C# Request not timing out

    - by Joel Kennedy
    I have this code which runs in a BackgroundWorker, and should make a POST request to the server and get a response. It works fine when it is supposed to work, but when I try to induce a 404 error it doesn't catch the error reporting system. loginProcess.DoWork += delegate(object s, DoWorkEventArgs args) { // loginProcess BackgroundWorker try { // Try to login, if error, report loginProcess.ReportProgress(10); String method = "POST"; String postdata = "postdata=test"; String url = "http://localhost/dev/login.php"; loginProcess.ReportProgress(15); WebRequest rqst = HttpWebRequest.Create(url); rqst.Timeout = 5000; ((HttpWebRequest)rqst).KeepAlive = true; loginProcess.ReportProgress(20); //rqst.Timeout = this.Timeout; // only needed, if you use HTTP AUTH //CredentialCache creds = new CredentialCache(); //creds.Add(new Uri(url), "Basic", new NetworkCredential(this.Uname, this.Pwd)); //rqst.Credentials = creds; rqst.Method = method; if (!String.IsNullOrEmpty(postdata)) { //rqst.ContentType = "application/xml"; rqst.ContentType = "application/x-www-form-urlencoded"; loginProcess.ReportProgress(30); byte[] byteData = UTF8Encoding.UTF8.GetBytes(postdata); loginProcess.ReportProgress(40); rqst.ContentLength = byteData.Length; loginProcess.ReportProgress(50); using (Stream postStream = rqst.GetRequestStream()) { loginProcess.ReportProgress(50); postStream.Write(byteData, 0, byteData.Length); loginProcess.ReportProgress(60); postStream.Close(); loginProcess.ReportProgress(70); rqst.GetResponse().Close(); rqst.GetRequestStream().Close(); } } loginProcess.ReportProgress(90); using (var response1 = rqst.GetResponse()) { using (var responseStream1 = response1.GetResponseStream()) { using (var reader1 = new StreamReader(responseStream1)) { //StreamReader rsps = new StreamReader(rqst.GetResponse().GetResponseStream()); string strRsps = reader1.ReadToEnd(); loginProcess.ReportProgress(95); loginVars = strRsps; //rqst. //reader1.Close(); //rsps.Dispose(); } args.Result = "SUCCESS"; } } } catch(WebException err) { // Catch error and put into err variable if(err.Status == WebExceptionStatus.ProtocolError) { // If something is wrong with protocol LoginReporting.ErrorName = Convert.ToString(((HttpWebResponse)err.Response).StatusCode); LoginReporting.ErrorDescription = Convert.ToString(((HttpWebResponse)err.Response).StatusDescription); LoginReporting.ErrorNotes = "Error when logging in, Server returned: " + Convert.ToString(((HttpWebResponse)err.Response).StatusCode); LoginReporting.ErrorLocation = "LoginRequest.ProtocolError"; args.Result = "ERROR"; //MessageBox.Show(Convert.ToString(((HttpWebResponse)err.Response).StatusCode)); //MessageBox.Show(Convert.ToString(((HttpWebResponse)err.Response).StatusDescription)); } else { args.Result = "ERROR"; } } catch(Exception err) { // Catch unhandled error LoginReporting.ErrorName = Convert.ToString(err); LoginReporting.ErrorDescription = Convert.ToString(err.Message); LoginReporting.ErrorNotes = "Error when logging in, Server returned: " + Convert.ToString(err.Message); LoginReporting.ErrorLocation = "LoginRequest.ProtocolError"; args.Result = "ERROR"; } }; I have put a timeout on the request but it just doesn't work! Is this a bug, or am I doing something wrong here? Thanks

    A new programmer needs yourhelp. I'm working on a porject of re-developement of Java driver for the company's PIN pad terminals. the Java Api (CPXApplicationUpdate) will allow the applications in pinpads to be updated and to be downloaded at different speed (Baud rate). the Java Api was created. i followed the protocolto build the message. the message is to send to a RS-232 port. i'm trying to use setter and getter to let the code work as an API. import java.io.InputStream; import java.io.OutputStream; import java.util.Properties; public class CPXApplicationUpdate extends CPXCommand { private int speed; // TODO: temporary variable for baud rate test stub. // speed: baud rate of the maintenance application performing DL /** Creates a new instance of CPXApplicationUpdate */ public CPXApplicationUpdate() { speed = 9600; // no baud rate change CPXProcessor.logger.fine("-------CPXApplicationUpdate constructor"); // setParam("timeout", _cmdInfo.getDefaultParValue("timeout")); } public CPXApplicationUpdate(int speedinit) { speed = speedinit; // TODO: where to get the speed? wait for user input.

Now, i need to create a demo application to test if this java driver (Java Api) works. the value of the speed can be input by users (command line), or creat property files. how can i do that?

  • How to use rhythmbox-client on LAN?

    - by Kaustubh P
    A few days ago I had asked this question, and according to one suggestion, used rhythmote. It is a web-interface to change songs on a rhythmbox playing on some PC. However, its not what I had thought of, and I stumbled upon documentation for rhythmbox-client. I tried a few ways of using it, but was unsuccessful. Let me show you a few ways of how I did it. The rhythmbox is running at address 192.168.1.4, lets call it jukebox. Passing the address as a parameter Hoping that I would be able to see and browse through songs on the jukebox rhythmbox-client 192.168.1.4 But, I get this message (rhythmbox-client:8370): Rhythmbox-WARNING **: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. (rhythmbox-client:8370): Rhythmbox-WARNING **: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. SSH ssh -l jukebox 192.168.1.4 rhythmbox-client --print-playing Which spat this at me: (rhythmbox-client:9389): Rhythmbox-WARNING **: /bin/dbus-launch terminated abnormally with the following error: Autolaunch error: X11 initialization failed. rhythmbox-client as root gksudo rhythmbox-client 192.168.1.4 A rhythmbox client comes up, but with no music shown in the library. I am guessing this is running on my own computer. Can anyon tell me how rhythmbox-client is to be run, and is it even correct of me to think that I can get a rhythmbox window showing the songs on the jukebox? PS: There were a few other solutions mentioned, but I want to evaluate each and every one of them. Thanks.

  • cURL works but PHP cURL fails to internet [migrated]

    - by wrk2bike
    Trying to diagnose an issue using PHP to cURL to an Internet location on a RedHat Linux server. cURL is installed and working, and: <?php var_dump(curl_version()); ?> shows all the correct information in the output. The issue is I can use PHP to cURL to localhost on the box itself, but not the Internet (see below). Normally I'd suspect the firewall, but I can cURL from the command line to the Internet without a problem. The box can also update it's own software packages, etc. What am I missing? My test is: <?php function http_head_curl($url,$timeout=30) { $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_TIMEOUT, $timeout); curl_setopt($ch, CURLOPT_HEADER, 1); curl_setopt($ch, CURLOPT_NOBODY, 1); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $res = curl_exec($ch); if ($res === false) { throw new RuntimeException("cURL exception: ".curl_errno($ch).": ".curl_error($ch)); } return trim($res); } // Succeeds, displaying headers echo(http_head_curl('localhost')); // Fails: echo(http_head_curl('www.google.com')); ?>

  • Persistence problem when installing USB Ubuntu variant using Windows

    - by Derek Redfern
    I'm part of a project called One2One2Go - we're developing a Live USB Ubuntu variant for use in schools in Somerville, MA. We have the project files compiled into an iso, and when installed using the native Ubuntu Startup Disk Creator, the USB works fine. When installed using a tool on a Windows machine (LiLi at linuxliveusb.com or liveusb-creator at fedorahosted.org/liveusb-creator), the USB works, but does not have persistence. This happens even if the creator is specifically set to allocate an area for persistent files. When comparing files on sticks created in Windows or Ubuntu, the one file that is different is syslinux/syslinux.cfg. I have printed the contents of the file below: Installed on Windows: DEFAULT nomodset LABEL debug menu label ^debug kernel /casper/vmlinuz append boot=casper xforcevesa initrd=/casper/initrd.gz -- LABEL nomodset menu label ^nomodset kernel /casper/vmlinuz append boot=casper quiet splash nomodset initrd=/casper/initrd.gz -- LABEL memtest menu label ^Memory test kernel /install/memtest append - LABEL hd menu label ^Boot from first hard disk localboot 0x80 append - PROMPT 0 TIMEOUT 1 Installed on Ubuntu: DEFAULT nomodset LABEL debug menu label ^debug kernel /casper/vmlinuz append noprompt cdrom-detect/try-usb=true persistent boot=casper xforcevesa initrd=/casper/initrd.gz -- LABEL nomodset menu label ^nomodset kernel /casper/vmlinuz append noprompt cdrom-detect/try-usb=true persistent boot=casper quiet splash nomodset initrd=/casper/initrd.gz -- LABEL memtest menu label ^Memory test kernel /install/memtest append - LABEL hd menu label ^Boot from first hard disk localboot 0x80 append - PROMPT 0 TIMEOUT 1 For troubleshooting reasons, I changed the Windows-created syslinux.cfg to match the one created by Ubuntu and persistence worked on it. I think the problem is that on the stick created by Windows, there is no "persistent" flag, but I don't know why. Is this a problem with our disk image or with the creator? How would I go about fixing this problem? Thanks in advance for your help. Derek Redfern

    The question was born because lately we've seen a pretty odd (well, at least for us, for the first time) - error message in Google webmaster tools - "DNS lookup timeout" ... I was pretty sure that with eNom's 5 DNS servers (dns1... to dns5.name-services.com) we're pretty set... But it appears that from (Europe/Hungary), for example - dns1.name-services.com takes 170ms. to respond on a ping... while GoDaddy's ns75.domaincontrol.com - takes only 40 ms. to respond... and at the same time - dns2 to dns5.name-services.com - each result with a timeout error (on ping)... This issue came to our attention right in the final stages of optimizing our web-site (almost to death) - basically, just in time... I would love to move our domains to a fast (fastest?) and reliable DNS server.. - but how do I find one ? Also - I did the ping tests from various geographic locations (we have servers in many countries) and GoDaddy seemed to be faster than eNom almost in every case. I'd be very thankful for any hints on this! Edited: Well.. maybe this one does not have an answer, after all...

  • Kubuntu 12.04 - DNS Issues

    - by AndrewJesaitis
    Starting yesterday (6/11/12), I've been having many network problems. When requesting a page in chrome, the page hangs on "Sending request" and then will eventually timeout. I'm within a VPN that has it's own DNS server. I've tried to manually set my DNS through the Network-Manager applet and by editing /etc/network/interfaces. Having no luck I unlinked the resolv.conf file and dumped the contents of my old resolv.conf into it. Again having no luck, I deactivated the dnsmasq server in /etc/NetworkManager/NetworkManager.conf by commenting out the dns=dnsmasq. $ cat NetworkManager.conf [main] plugins=ifupdown,keyfile #dns=dnsmasq no-auto-default=D0:67:E5:EA:B6:6B, [ifupdown] managed=false $ nm-tool NetworkManager Tool State: connected (global) - Device: eth0 [Wired connection 1] ------------------------------------------- Type: Wired Driver: tg3 State: connected Default: yes HW Address: D0:67:E5:EA:B6:6B Capabilities: Carrier Detect: yes Speed: 1000 Mb/s Wired Properties Carrier: on IPv4 Settings: Address: 192.168.254.122 Prefix: 24 (255.255.255.0) Gateway: 192.168.254.2 DNS: 192.168.254.1 What is strange is that the network will work fine for a few minutes then start to timeout. A few minutes later it will work again. I'm unable to hit internal or external sites when it is timing out. When I $dig local sites, I receive no answer. I do receive an answer from google.com. At this point, I would usually blame the DNS Server, especially since when I change to Google's DNS server things work. But, I need to use our internal DNS to hit our internal sites. Nobody else is having issues and they are all using DHCP. This group includes one user who is using 11.04. At this point, I'm at a loss for what to do, so any help would be appreciated.

  • Does Hauppauge WinTV HVR-900 (r2) [USB ID 2040:6502] work with ubuntu 12.04 LTS?

    I have this DVB+Analog usb tv tuner Hauppauge WinTV HVR-900 (r2) [USB ID 2040:6502]. This used to work under ubuntu 10.04 LTS. But in 12.04 there seems to be a problem.

  • Why doesn't my grub background show?

    I've tried to change resolution, colors and background image for my grub menu, but I get no background (well, just a black one, no image).... What am I doing wrong?

  • Am I the only one this anal / obsessive about code? [closed]

    - by Chris
    While writing a shared lock class for sql server for a web app tonight, I found myself writing in the code style below as I always do: private bool acquired; private bool disposed; private TimeSpan timeout; private string connectionString; private Guid instance = Guid.NewGuid(); private Thread autoRenewThread; Basically, whenever I'm declaring a group of variables or writing a sql statement or any coding activity involving multiple related lines, I always try to arrange them where possible so that they form a bell curve (imagine rotating the text 90deg CCW). As an example of something that peeves the hell out of me, consider the following alternative: private bool acquired; private bool disposed; private string connectionString; private Thread autoRenewThread; private Guid instance = Guid.NewGuid(); private TimeSpan timeout; In the above example, declarations are grouped (arbitrarily) so that the primitive types appear at the top. When viewing the code in Visual Studio, primitive types are a different color than non-primitives, so the grouping makes sense visually, if for no other reason. But I don't like it because the right margin is less of an aesthetic curve. I've always chalked this up to being OCD or something, but at least in my mind, the code is "prettier". Am I the only one?

  • Can't start system due to mdadm failing

    - by user101212
    I used to have a 5-disk RAID5 partition, all working very well. I have then decided to add 3 more disks on it, totaling 8 equal disks. I've opened Webmin and just asked to add the disks. Then I've realized the three disks had NTFS partitions, wich mdadm didn't complain, so I tried to stop the growing to remove the Windows partitions. I've tried to remove a disk using the same Webmin, but (as you might guess and call me fool...), the system became unstable. By restarting the system, I've started receiving these messages: "udev[126]: timeout: killing '/sbin/mdadm --incremental /dev/sdh1' [311]" "udev[124]: timeout: killing '/sbin/mdadm --detail --export /dev/md0' [316]" I've formated the system disk, hoping to get a system up and running. I did that with all RAID disks disconected, so everything was fine. I then reconnected the disks, wich was also ok. And finally installed mdadm using apt-get. By reboot, the system has found the mdadm intention of growing the system, so the same messages appear again. I other words: I can't even reach a command prompt to do something. Any ideas of what to do? I believe I could turn off the system, disconnect the disks and look for the mdadm.conf file. Would that be a good idead? I'm no Linux expert, so I'm really lost here.

  • How do I add a boot from cd option to yaboot?

    - by Sergiu
    So I'm dual-booting Ubuntu 12.04.1 on my iMac G5 powepc alongside Mac OS X and I want to add a boot cd option to yaboot because I'm trying to boot a scratched Mac OS X installation DVD that takes a while to read and the frst bootstrap moves on too fast. How do I edit the timeout for the first bootstrap anyways? So, my main question is, how do I add a cd booting option to yaboot and then, how doI boot it? The devalias from OpenFrmware tells me that 1 have 2 cd-rom instaled, on is /ht/pci@3/ata-6/disk@0 and the other on ends with a 1 instead of a zero. These are the contents of my yaboot.conf file: yaboot.conf generated by the Ubuntu installer run: "man yaboot.conf" for details. Do not make changes until you have!! see also: /usr/share/doc/yaboot/examples for example configurations. For a dual-boot menu, add one or more of: bsd=/dev/hdaX, macos=/dev/hdaY, macosx=/dev/hdaZ boot="/dev/disk/by-id/scsi-SATA_ST3160023AS_5MT1GCWA-part2" device=/ht@0,f2000000/pci@3/k2-sata-root@c/@0/@0 partition=4 root="UUID=798a048f-ee48-49e0-bba3-111aed8dee04" timeout=12000 install=/usr/lib/yaboot/yaboot magicboot=/usr/lib/yaboot/ofboot enablecdboot macosx="/dev/disk/by-id/scsi-SATA_ST3160023AS_5MT1GCWA-part3" image=/boot/vmlinux label=Linux read-only initrd=/boot/initrd.img append="quiet splash" What do I add here so that yaboot will boot from my cd in like 3 minutes after startup? Thanks!

  • Bulk inserting best way to about it? + Helping me understand fully what I found so far

    - by chobo2
    Hi So I saw this post here and read it and it seems like bulk copy might be the way to go. http://stackoverflow.com/questions/682015/whats-the-best-way-to-bulk-database-inserts-from-c I still have some questions and want to know how things actually work. So I found 2 tutorials. http://www.codeproject.com/KB/cs/MultipleInsertsIn1dbTrip.aspx#_Toc196622241 http://www.codeproject.com/KB/linq/BulkOperations_LinqToSQL.aspx First way uses 2 ado.net 2.0 features. BulkInsert and BulkCopy. the second one uses linq to sql and OpenXML. This sort of appeals to me as I am using linq to sql already and prefer it over ado.net. However as one person pointed out in the posts what he just going around the issue at the cost of performance( nothing wrong with that in my opinion) First I will talk about the 2 ways in the first tutorial I am using VS2010 Express, .net 4.0, MVC 2.0, SQl Server 2005 Is ado.net 2.0 the most current version? Based on the technology I am using, is there some updates to what I am going to show that would improve it somehow? Is there any thing that these tutorial left out that I should know about? BulkInsert I am using this table for all the examples. CREATE TABLE [dbo].[TBL_TEST_TEST] ( ID INT IDENTITY(1,1) PRIMARY KEY, [NAME] [varchar](50) ) SP Code USE [Test] GO /****** Object: StoredProcedure [dbo].[sp_BatchInsert] Script Date: 05/19/2010 15:12:47 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[sp_BatchInsert] (@Name VARCHAR(50) ) AS BEGIN INSERT INTO TBL_TEST_TEST VALUES (@Name); END C# Code /// <summary> /// Another ado.net 2.0 way that uses a stored procedure to do a bulk insert. /// Seems slower then "BatchBulkCopy" way and it crashes when you try to insert 500,000 records in one go. /// http://www.codeproject.com/KB/cs/MultipleInsertsIn1dbTrip.aspx#_Toc196622241 /// </summary> private static void BatchInsert() { // Get the DataTable with Rows State as RowState.Added DataTable dtInsertRows = GetDataTable(); SqlConnection connection = new SqlConnection(connectionString); SqlCommand command = new SqlCommand("sp_BatchInsert", connection); command.CommandType = CommandType.StoredProcedure; command.UpdatedRowSource = UpdateRowSource.None; // Set the Parameter with appropriate Source Column Name command.Parameters.Add("@Name", SqlDbType.VarChar, 50, dtInsertRows.Columns[0].ColumnName); SqlDataAdapter adpt = new SqlDataAdapter(); adpt.InsertCommand = command; // Specify the number of records to be Inserted/Updated in one go. Default is 1. adpt.UpdateBatchSize = 1000; connection.Open(); int recordsInserted = adpt.Update(dtInsertRows); connection.Close(); } So first thing is the batch size. Why would you set a batch size to anything but the number of records you are sending? Like I am sending 500,000 records so I did a Batch size of 500,000. Next why does it crash when I do this? If I set it to 1000 for batch size it works just fine. System.Data.SqlClient.SqlException was unhandled Message="A transport-level error has occurred when sending the request to the server. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)"

Next I looked at bulkcopy /// <summary> /// An ado.net 2.0 way to mass insert records. This seems to be the fastest. /// http://www.codeproject.com/KB/cs/MultipleInsertsIn1dbTrip.aspx#_Toc196622241 /// </summary> private static void BatchBulkCopy() { // Get the DataTable DataTable dtInsertRows = GetDataTable(); using (SqlBulkCopy sbc = new SqlBulkCopy(connectionString, SqlBulkCopyOptions.KeepIdentity)) { sbc.DestinationTableName = "TBL_TEST_TEST"; // Number of records to be processed in one go sbc.BatchSize = 500000; // Map the Source Column from DataTabel to the Destination Columns in SQL Server 2005 Person Table // sbc.ColumnMappings.Add("ID", "ID"); sbc.ColumnMappings.Add("NAME", "NAME"); // Number of records after which client has to be notified about its status sbc.NotifyAfter = dtInsertRows.Rows.Count; // Event that gets fired when NotifyAfter number of records are processed. sbc.SqlRowsCopied += new SqlRowsCopiedEventHandler(sbc_SqlRowsCopied); // Finally write to server sbc.WriteToServer(dtInsertRows); sbc.Close(); } } This one seemed to go really fast and did not even need a SP( can you use SP with bulk copy? If you can would it be better?) BatchCopy had no problem with a 500,000 batch size.So again why make it smaller then the number of records you want to send? I found that with BatchCopy and 500,000 batch size it took only 5 seconds to complete. I then tried with a batch size of 1,000 and it only took 8 seconds. So much faster then the bulkinsert one above. Now I tried the other tutorial. USE [Test] GO /****** Object: StoredProcedure [dbo].[spTEST_InsertXMLTEST_TEST] Script Date: 05/19/2010 15:39:03 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[spTEST_InsertXMLTEST_TEST](@UpdatedProdData nText) AS DECLARE @hDoc int exec sp_xml_preparedocument @hDoc OUTPUT,@UpdatedProdData INSERT INTO TBL_TEST_TEST(NAME) SELECT XMLProdTable.NAME FROM OPENXML(@hDoc, 'ArrayOfTBL_TEST_TEST/TBL_TEST_TEST', 2) WITH ( ID Int, NAME varchar(100) ) XMLProdTable EXEC sp_xml_removedocument @hDoc C# code. /// <summary> /// This is using linq to sql to make the table objects. /// It is then serailzed to to an xml document and sent to a stored proedure /// that then does a bulk insert(I think with OpenXML) /// http://www.codeproject.com/KB/linq/BulkOperations_LinqToSQL.aspx /// </summary> private static void LinqInsertXMLBatch() { using (TestDataContext db = new TestDataContext()) { TBL_TEST_TEST[] testRecords = new TBL_TEST_TEST[500000]; for (int count = 0; count < 500000; count++) { TBL_TEST_TEST testRecord = new TBL_TEST_TEST(); testRecord.NAME = "Name : " + count; testRecords[count] = testRecord; } StringBuilder sBuilder = new StringBuilder(); System.IO.StringWriter sWriter = new System.IO.StringWriter(sBuilder); XmlSerializer serializer = new XmlSerializer(typeof(TBL_TEST_TEST[])); serializer.Serialize(sWriter, testRecords); db.insertTestData(sBuilder.ToString()); } } So I like this because I get to use objects even though it is kinda redundant. I don't get how the SP works. Like I don't get the whole thing. I don't know if OPENXML has some batch insert under the hood but I do not even know how to take this example SP and change it to fit my tables since like I said I don't know what is going on. I also don't know what would happen if the object you have more tables in it. Like say I have a ProductName table what has a relationship to a Product table or something like that. In linq to sql you could get the product name object and make changes to the Product table in that same object. So I am not sure how to take that into account. I am not sure if I would have to do separate inserts or what. The time was pretty good for 500,000 records it took 52 seconds The last way of course was just using linq to do it all and it was pretty bad. /// <summary> /// This is using linq to sql to to insert lots of records. /// This way is slow as it uses no mass insert. /// Only tried to insert 50,000 records as I did not want to sit around till it did 500,000 records. /// http://www.codeproject.com/KB/linq/BulkOperations_LinqToSQL.aspx /// </summary> private static void LinqInsertAll() { using (TestDataContext db = new TestDataContext()) { db.CommandTimeout = 600; for (int count = 0; count < 50000; count++) { TBL_TEST_TEST testRecord = new TBL_TEST_TEST(); testRecord.NAME = "Name : " + count; db.TBL_TEST_TESTs.InsertOnSubmit(testRecord); } db.SubmitChanges(); } } I did only 50,000 records and that took over a minute to do. So I really narrowed it done to the linq to sql bulk insert way or bulk copy. I am just not sure how to do it when you have relationship for either way. I am not sure how they both stand up when doing updates instead of inserts as I have not gotten around to try it yet. I don't think I will ever need to insert/update more than 50,000 records at one type but at the same time I know I will have to do validation on records before inserting so that will slow it down and that sort of makes linq to sql nicer as your got objects especially if your first parsing data from a xml file before you insert into the database.

  • Algorithmia Source Code released on CodePlex

    - by FransBouma
    Following the release of our BCL Extensions Library on CodePlex, we have now released the source-code of Algorithmia on CodePlex! Algorithmia is an algorithm and data-structures library for .NET 3.5 or higher and is one of the pillars LLBLGen Pro v3's designer is built on. The library contains many data-structures and algorithms, and the source-code is well documented and commented, often with links to official descriptions and papers of the algorithms and data-structures implemented. The source-code is shared using Mercurial on CodePlex and is licensed under the friendly BSD2 license. User documentation is not available at the moment but will be added soon. One of the main design goals of Algorithmia was to create a library which contains implementations of well-known algorithms which weren't already implemented in .NET itself. This way, more developers out there can enjoy the results of many years of what the field of Computer Science research has delivered. Some algorithms and datastructures are known in .NET but are re-implemented because the implementation in .NET isn't efficient for many situations or lacks features. An example is the linked list in .NET: it doesn't have an O(1) concat operation, as every node refers to the containing LinkedList object it's stored in. This is bad for algorithms which rely on O(1) concat operations, like the Fibonacci heap implementation in Algorithmia. Algorithmia therefore contains a linked list with an O(1) concat feature. The following functionality is available in Algorithmia: Command, Command management. This system is usable to build a fully undo/redo aware system by building your object graph using command-aware classes. The Command pattern is implemented using a system which allows transparent undo-redo and command grouping so you can use it to make a class undo/redo aware and set properties, use its contents without using commands at all. The Commands namespace is the namespace to start. Classes you'd want to look at are CommandifiedMember, CommandifiedList and KeyedCommandifiedList. See the CommandQueueTests in the test project for examples. Graphs, Graph algorithms. Algorithmia contains a sophisticated graph class hierarchy and algorithms implemented onto them: non-directed and directed graphs, as well as a subgraph view class, which can be used to create a view onto an existing graph class which can be self-maintaining. Algorithms include transitive closure, topological sorting and others. A feature rich depth-first search (DFS) crawler is available so DFS based algorithms can be implemented quickly. All graph classes are undo/redo aware, as they can be set to be 'commandified'. When a graph is 'commandified' it will do its housekeeping through commands, which makes it fully undo-redo aware, so you can remove, add and manipulate the graph and undo/redo the activity automatically without any extra code. If you define the properties of the class you set as the vertex type using CommandifiedMember, you can manipulate the properties of vertices and the graph contents with full undo/redo functionality without any extra code. Heaps. Heaps are data-structures which have the largest or smallest item stored in them always as the 'root'. Extracting the root from the heap makes the heap determine the next in line to be the 'maximum' or 'minimum' (max-heap vs. min-heap, all heaps in Algorithmia can do both). Algorithmia contains various heaps, among them an implementation of the Fibonacci heap, one of the most efficient heap datastructures known today, especially when you want to merge different instances into one. Priority queues. Priority queues are specializations of heaps. Algorithmia contains a couple of them. Sorting. What's an algorithm library without sort algorithms? Algorithmia implements a couple of sort algorithms which sort the data in-place. This aspect is important in situations where you want to sort the elements in a buffer/list/ICollection in-place, so all data stays in the data-structure it already is stored in. PropertyBag. It re-implements Tony Allowatt's original idea in .NET 3.5 specific syntax, which is to have a generic property bag and to be able to build an object in code at runtime which can be bound to a property grid for editing. This is handy for when you have data / settings stored in XML or other format, and want to create an editable form of it without creating many editors. IEditableObject/IDataErrorInfo implementations. It contains default implementations for IEditableObject and IDataErrorInfo (EditableObjectDataContainer for IEditableObject and ErrorContainer for IDataErrorInfo), which make it very easy to implement these interfaces (just a few lines of code) without having to worry about bookkeeping during databinding. They work seamlessly with CommandifiedMember as well, so your undo/redo aware code can use them out of the box. EventThrottler. It contains an event throttler, which can be used to filter out duplicate events in an event stream coming into an observer from an event. This can greatly enhance performance in your UI without needing to do anything other than hooking it up so it's placed between the event source and your real handler. If your UI is flooded with events from data-structures observed by your UI or a middle tier, you can use this class to filter out duplicates to avoid redundant updates to UI elements or to avoid having observers choke on many redundant events. Small, handy stuff. A MultiValueDictionary, which can store multiple unique values per key, instead of one with the default Dictionary, and is also merge-aware so you can merge two into one. A Pair class, to quickly group two elements together. Multiple interfaces for helping with building a de-coupled, observer based system, and some utility extension methods for the defined data-structures. We regularly update the library with new code. If you have ideas for new algorithms or want to share your contribution, feel free to discuss it on the project's Discussions page or send us a pull request. Enjoy!

  • AWS: setting up auto-scale for EC2 instances

    - by Elton Stoneman
    Originally posted on: http://geekswithblogs.net/EltonStoneman/archive/2013/10/16/aws-setting-up-auto-scale-for-ec2-instances.aspxWith Amazon Web Services, there’s no direct equivalent to Azure Worker Roles – no Elastic Beanstalk-style application for .NET background workers. But you can get the auto-scale part by configuring an auto-scaling group for your EC2 instance. This is a step-by-step guide, that shows you how to create the auto-scaling configuration, which for EC2 you need to do with the command line, and then link your scaling policies to CloudWatch alarms in the Web console. I’m using queue size as my metric for CloudWatch,  which is a good fit if your background workers are pulling messages from a queue and processing them.  If the queue is getting too big, the “high” alarm will fire and spin up a new instance to share the workload. If the queue is draining down, the “low” alarm will fire and shut down one of the instances. To start with, you need to manually set up your app in an EC2 VM, for a background worker that would mean hosting your code in a Windows Service (I always use Topshelf). If you’re dual-running Azure and AWS, then you can isolate your logic in one library, with a generic entry point that has Start() and Stop()  functions, so your Worker Role and Windows Service are essentially using the same code. When you have your instance set up with the Windows Service running automatically, and you’ve tested it starts up and works properly from a reboot, shut the machine down and take an image of the VM, using Create Image (EBS AMI) from the Web Console: When that completes, you’ll have your own AMI which you can use to spin up new instances, and you’re ready to create your auto-scaling group. You need to dip into the command-line tools for this, so follow this guide to set up the AWS autoscale command line tool. Now we’re ready to go. 1. Create a launch configuration This launch configuration tells AWS what to do when a new instance needs to be spun up. You create it with the as-create-launch-config command, which looks like this: as-create-launch-config sc-xyz-launcher # name of the launch config --image-id ami-7b9e9f12 # id of the AMI you extracted from your VM --region eu-west-1 # which region the new instance gets created in --instance-type t1.micro # size of the instance to create --group quicklaunch-1 #security group for the new instance 2. Create an auto-scaling group The auto-scaling group links to the launch config, and defines the overall configuration of the collection of instances: as-create-auto-scaling-group sc-xyz-asg # auto-scaling group name --region eu-west-1 # region to create in --launch-configuration sc-xyz-launcher # name of the launch config to invoke for new instances --min-size 1 # minimum number of nodes in the group --max-size 5 # maximum number of nodes in the group --default-cooldown 300 # period to wait (in seconds) after each scaling event, before checking if another scaling event is required --availability-zones eu-west-1a eu-west-1b eu-west-1c # which availability zones you want your instances to be allocated in – multiple entries means EC@ will use any of them 3. Create a scale-up policy The policy dictates what will happen in response to a scaling event being triggered from a “high” alarm being breached. It links to the auto-scaling group; this sample results in one additional node being spun up: as-put-scaling-policy scale-up-policy # policy name -g sc-psod-woker-asg # auto-scaling group the policy works with --adjustment 1 # size of the adjustment --region eu-west-1 # region --type ChangeInCapacity # type of adjustment, this specifies a fixed number of nodes, but you can use PercentChangeInCapacity to make an adjustment relative to the current number of nodes, e.g. increasing by 50% 4. Create a scale-down policy The policy dictates what will happen in response to a scaling event being triggered from a “low” alarm being breached. It links to the auto-scaling group; this sample results in one node from the group being taken offline: as-put-scaling-policy scale-down-policy -g sc-psod-woker-asg "--adjustment=-1" # in Windows, use double-quotes to surround a negative adjustment value –-type ChangeInCapacity --region eu-west-1 5. Create a “high” CloudWatch alarm We’re done with the command line now. In the Web Console, open up the CloudWatch view and create a new alarm. This alarm will monitor your metrics and invoke the scale-up policy from your auto-scaling group, when the group is working too hard. Configure your metric – this example will fire the alarm if there are more than 10 messages in my queue for over a minute: Then link the alarm to the scale-up policy in your group: 6. Create a “low” CloudWatch alarm The opposite of step 4, this alarm will trigger when the instances in your group don’t have enough work to do (e.g fewer than 2 messages in the queue for 1 minute), and will invoke the scale-down policy. And that’s it. You don’t need your original VM as the auto-scale group has a minimum number of nodes connected. You can test out the scaling by flexing your CloudWatch metric – in this example, filling up a queue from a  stub publisher – and watching AWS create new nodes as required, then stopping the publisher and watch AWS kill off the spare nodes.

  • 7u10: JavaFX packaging tools update

    - by igor
    Last weeks were very busy here in Oracle. JavaOne 2012 is next week. Come to see us there! Meanwhile i'd like to quickly update you on recent developments in the area of packaging tools. This is an area of ongoing development for the team, and we are  continuing to refine and improve both the tools and the process. Thanks to everyone who shared experiences and suggestions with us. We are listening and fixed many of reported issues. Please keep them coming as comments on the blog or (even better) file issues directly to the JIRA. In this post i'll focus on several new packaging features added in JDK 7 update 10: Self-Contained Applications: Select Java Runtime to bundle Self-Contained Applications: Create Package without Java Runtime Self-Contained Applications: Package non-JavaFX application Option to disable proxy setup in the JavaFX launcher Ability to specify codebase for WebStart application Option to update existing jar file Self-Contained Applications: Specify application icon Self-Contained Applications: Pass parameters on the command line All these features and number of other important bug fixes are available in the developer preview builds of JDK 7 update 10 (build 8 or later). Please give them a try and share your feedback! Self-Contained Applications: Select Java Runtime to bundle Packager tools in 7u6 assume current JDK (based on java.home property) is the source for embedded runtime. This is useful simplification for many scenarios but there are cases where ability to specify what to embed explicitly is handy. For example IDE may be using fixed JDK to build the project and this is not the version you want to bundle into your application. To make it more flexible we now allow to specify location of base JDK explicitly. It is optional and if you do not specify it then current JDK will be used (i.e. this change is fully backward compatible). New 'basedir' attribute was added to <fx:platform> tag. Its value is location of JDK to be used. It is ok to point to either JRE inside the JDK or JDK top level folder. However, it must be JDK and not JRE as we need other JDK tools for proper packaging and it must be recent version of JDK that is bundled with JavaFX (i.e. Java 7 update 6 or later). Here are examples (<fx:platform> is part of <fx:deploy> task): <fx:platform basedir="${java.home}"/> <fx:platform basedir="c:\tools\jdk7"/> Hint: this feature enables you to use packaging tools from JDK 7 update 10 (and benefit from bug fixes and other features described below) to create application package with bundled FCS version of JRE 7 update 6. Self-Contained Applications: Create Package without Java Runtime This may sound a bit puzzling at first glance. Package without embedded Java Runtime is not really self-contained and obviously will not help with: Deployment on fresh systems. JRE need to be installed separately (and this step will require admin permissions). Possible compatibility issues due to updates of system runtime. However, these packages are much much smaller in size. If download size matters and you are confident that user have recommended system JRE installed then this may be good option to consider if you want to improve user experience for install and launch. Technically, this is implemented as an extension of previous feature. Pass empty string as value for 'basedir' attribute and this will be treated as request to not bundle Java runtime, e.g. <fx:platform basedir=""/> Self-Contained Applications: Package non-JavaFX application One of popular questions people ask about self-contained applications - can i package my Java application as self-contained application? Absolutely. This is true even for tools shipped with JDK 7 update 6. Simply follow steps for creating package for Swing application with integrated JavaFX content and they will work even if your application does not use JavaFX. What's wrong with it? Well, there are few caveats: bundle size is larger because JavaFX is bundled whilst it is not really needed main application jar needs to be packaged to comply to JavaFX packaging requirements(and this may be not trivial to achieve in your existing build scripts) javafx application launcher may not work well with startup logic of your application (for example launcher will initialize networking stack and this may void custom networking settings in your application code) In JDK 7 update 6 <fx:deploy> was updated to accept arbitrary executable jar as an input. Self-contained application package will be created preserving input jar as-is, i.e. no JavaFX launcher will be embedded. This does not help with first point above but resolves other two. More formally following assertions must be true for packaging to succeed: application can be launched as "java -jar YourApp.jar" from the command line  mainClass attribute of <fx:application> refers to application main class <fx:resources> lists all resources needed for the application To give you an example lets assume we need to create a bundle for application consisting of 3 jars:     dist/javamain.jar     dist/lib/somelib.jar    dist/morelibs/anotherlib.jar where javamain.jar has manifest with      Main-Class: app.Main     Class-Path: lib/somelib.jar morelibs/anotherlib.jar Here is sample ant code to package it: <target name="package-bundle"> <taskdef resource="com/sun/javafx/tools/ant/antlib.xml" uri="javafx:com.sun.javafx.tools.ant" classpath="${javafx.tools.ant.jar}"/> <fx:deploy nativeBundles="all" width="100" height="100" outdir="native-packages/" outfile="MyJavaApp"> <info title="Sample project" vendor="Me" description="Test built from Java executable jar"/> <fx:application id="myapp" version="1.0" mainClass="app.Main" name="MyJavaApp"/> <fx:resources> <fx:fileset dir="dist"> <include name="javamain.jar"/> <include name="lib/somelib.jar"/> <include name="morelibs/anotherlib.jar"/> </fx:fileset> </fx:resources> </fx:deploy> </target> Option to disable proxy setup in the JavaFX launcher Since JavaFX 2.2 (part of JDK 7u6) properly packaged JavaFX applications  have proxy settings initialized according to Java Runtime configuration settings. This is handy for most of the application accessing network with one exception. If your application explicitly sets networking properties (e.g. socksProxyHost) then they must be set before networking stack is initialized. Proxy detection will initialize networking stack and therefore your custom settings will be ignored. One way to disable proxy setup by the embedded JavaFX launcher is to pass "-Djavafx.autoproxy.disable=true" on the command line. This is good for troubleshooting (proxy detection may cause significant startup time increases if network is misconfigured) but not really user friendly. Now proxy setup will be disabled if manifest of main application jar has "JavaFX-Feature-Proxy" entry with value "None". Here is simple example of adding this entry using <fx:jar> task: <fx:jar destfile="dist/sampleapp.jar"> <fx:application refid="myapp"/> <fx:resources refid="myresources"/> <fileset dir="build/classes"/> <manifest> <attribute name="JavaFX-Feature-Proxy" value="None"/> </manifest> </fx:jar> Ability to specify codebase for WebStart application JavaFX applications do not need to specify codebase (i.e. absolute location where application code will be deployed) for most of real world deployment scenarios. This is convenient as application does not need to be modified when it is moved from development to deployment environment. However, some developers want to ensure copies of their application JNLP file will redirect to master location. This is where codebase is needed. To avoid need to edit JNLP file manually <fx:deploy> task now accepts optional codebase attribute. If attribute is not specified packager will generate same no-codebase files as before. If codebase value is explicitly specified then generated JNLP files (including JNLP content embedded into web page) will use it.  Here is an example: <fx:deploy width="600" height="400" outdir="Samples" codebase="http://localhost/codebaseTest" outfile="TestApp"> .... </fx:deploy> Option to update existing jar file JavaFX packaging procedures are optimized for new application that can use ant or command line javafxpackager utility. This may lead to some redundant steps when you add it to your existing build process. One typical situation is that you might already have a build procedure that produces executable jar file with custom manifest. To properly package it as JavaFX executable jar you would need to unpack it and then use javafxpackager or <fx:jar> to create jar again (and you need to make sure you pass all important details from your custom manifest). We added option to pass jar file as an input to javafxpackager and <fx:jar>. This simplifies integration of JavaFX packaging tools into existing build  process as postprocessing step. By the way, we are looking for ways to simplify this further. Please share your suggestions! On the technical side this works as follows. Both <fx:jar> and javafxpackager will attempt to update existing jar file if this is the only input file. Update process will add JavaFX launcher classes and update the jar manifest with JavaFX attributes. Your custom attributes will be preserved. Update could be performed in place or result may be saved to a different file. Main-Class and Class-Path elements (if present) of manifest of input jar file will be used for JavaFX application  unless they are explicitly overriden in the packaging command you use. E.g. attribute mainClass of <fx:application> (or -appclass in the javafxpackager case) overrides existing Main-Class in the jar manifest. Note that class specified in the Main-Class attribute could either extend JavaFX Application or provide static main() method. Here are examples of updating jar file using javafxpackager: Create new JavaFX executable jar as a copy of given jar file javafxpackager -createjar -srcdir dist -srcfiles fish_proto.jar -outdir dist -outfile fish.jar  Update existing jar file to be JavaFX executable jar and use test.Fish as main application class javafxpackager -createjar -srcdir dist -appclass test.Fish -srcfiles fish.jar -outdir dist -outfile fish.jar  And here is example of using <fx:jar> to create new JavaFX executable jar from the existing fish_proto.jar: <fx:jar destfile="dist/fish.jar"> <fileset dir="dist"> <include name="fish_proto.jar"/> </fileset> </fx:jar> Self-Contained Applications: Specify application icon The only way to specify application icon for self-contained application using tools in JDK 7 update 6 is to use drop-in resources. Now this bug is resolved and you can also specify icon using <fx:icon> tag. Here is an example: <fx:deploy ...> <fx:info> <fx:icon href="default.png"/> </fx:info> ... </fx:deploy> Few things to keep in mind: Only default kind of icon is applicable to self-contained applications (as of now) Icon should follow platform specific rules for sizes and image format (e.g. .ico on Windows and .icns on Mac) Self-Contained Applications: Pass parameters on the command line JavaFX applications support two types of application parameters: named and unnamed (see the API for Application.Parameters). Static named parameters can be added to the application package using <fx:param> and unnamed parameters can be added using <fx:argument>. They are applicable to all execution modes including standalone applications. It is also possible to pass parameters to a JavaFX application from a Web page that hosts it, using <fx:htmlParam>.  Prior to JavaFX 2.2, this was only supported for embedded applications. Starting from JavaFX 2.2, <fx:htmlParam> is applicable to Web Start applications also. See JavaFX deployment guide for more details on this. However, there was no way to pass dynamic parameters to the self-contained application. This has been improved and now native launchers will  delegate parameters from command line to the application code. I.e. to pass parameter to the application you simply need to run it as "myapp.exe somevalue" and then use getParameters().getUnnamed().get(0) to get "somevalue".
