• Unaccounted for database size

  - by Nazadus

  I currently have a database that is 20GB in size. I've run a few scripts which show on each tables size (and other incredibly useful information such as index stuff) and the biggest table is 1.1 million records which takes up 150MB of data. We have less than 50 tables most of which take up less than 1MB of data. After looking at the size of each table I don't understand why the database shouldn't be 1GB in size after a shrink. The amount of available free space that SqlServer (2005) reports is 0%. The log mode is set to simple. At this point my main concern is I feel like I have 19GB of unaccounted for used space. Is there something else I should look at? Normally I wouldn't care and would make this a passive research project except this particular situation calls for us to do a backup and restore on a weekly basis to put a copy on a satellite (which has no internet, so it must be done manually). I'd much rather copy 1GB (or even if it were down to 5GB!) than 20GB of data each week. sp_spaceused reports the following: Navigator-Production 19184.56 MB 3.02 MB And the second part of it: 19640872 KB 19512112 KB 108184 KB 20576 KB while I've found a few other scripts (such as the one from two of the server database size questions here, they all report the same information either found above or below). The script I am using is from SqlTeam. Here is the header info: * BigTables.sql * Bill Graziano (SQLTeam.com) * graz@<email removed> * v1.11 The top few tables show this (table, rows, reserved space, data, index, unused, etc): Activity 1143639 131 MB 89 MB 41768 KB 1648 KB 46% 1% EventAttendance 883261 90 MB 58 MB 32264 KB 328 KB 54% 0% Person 113437 31 MB 15 MB 15752 KB 912 KB 103% 3% HouseholdMember 113443 12 MB 6 MB 5224 KB 432 KB 82% 4% PostalAddress 48870 8 MB 6 MB 2200 KB 280 KB 36% 3% The rest of the tables are either the same in size or smaller. No more than 50 tables. Update 1: - All tables use unique identifiers. Usually an int incremented by 1 per row. I've also re-indexed everything. I ran the dbcc shrink command as well as updating the usage before and after. And over and over. An interesting thing I found is that when I restarted the server and confirmed no one was using it (and no maintenance procs are running, this is a very new application -- under a week old) and when I went to run the shrink, every now and then it would say something about data changed. Googling yielded too few useful answers with the obvious not applying (it was 1am and I disconnected everyone, so it seems impossible that was really the case). The data was migrated via C# code which basically looked at another server and brought things over. The quantity of deletes, at this point in time, are probably under 50k in rows. Even if those rows were the biggest rows, that wouldn't be more than 100M I would imagine. When I go to shrink via the GUI it reports 0% available to shrink, indicating that I've already gotten it as small as it thinks it can go. Update 2: sp_spaceused 'Activity' yields this (which seems right on the money): Activity 1143639 134488 KB 91072 KB 41768 KB 1648 KB Fill factor was 90. All primary keys are ints. Here is the command I used to 'updateusage': DBCC UPDATEUSAGE(0); Update 3: Per Edosoft's request: Image 111975 2407773 19262184 It appears as though the image table believes it's the 19GB portion. I don't understand what this means though. Is it really 19GB or is it misrepresented? Update 4: Talking to a co-worker and I found out that it's because of the pages, as someone else here has also state the potential for that. The only index on the image table is a clustered PK. Is this something I can fix or do I just have to deal with it? The regular script shows the Image table to be 6MB in size. Update 5: I think I'm just going to have to deal with it after further research. The images have been resized to be roughly 2-5KB each and on a normal file system doesn't consume much space but on SqlServer it seems to consume considerably more. The real answer, in the long run, will likely be separating that table in to another partition or something similar.

• Everytime user types , in my text box i want it to become ',' or help me do it using a parameter

  - by MyHeadHurts

  I am using a vb.net textbox to become part of my IN sql statement in my program I tryed to use a parameter and it didn't work here is my code TextBox1.Text = "'Cruises','Caribbean and

runs much faster. if the user did click the checkbox then the textbox where they type the specific regions shows up and it will run the query that includes the dbo.B605SaleAsOfAdvancedMaster.SDESCR in

• Fastest way to parse XML files in C#?

  I have to load many XML files from internet. But for testing with better speed i downloaded all of them (more than 500 files) of the following format. <player-profile> <personal-information> <id>36</id> <fullname>Adam Gilchrist</fullname> <majorteam>Australia</majorteam> <nickname>Gilchrist</nickname> <shortName>A Gilchrist</shortName> <dateofbirth>Nov 14, 1971</dateofbirth> <battingstyle>Left-hand bat</battingstyle> <bowlingstyle>Right-arm offbreak</bowlingstyle> <role>Wicket-Keeper</role> <teams-played-for>Western Australia, New South Wales, ICC World XI, Deccan Chargers, Australia</teams-played-for> <iplteam>Deccan Chargers</iplteam> </personal-information> <batting-statistics> <odi-stats> <matchtype>ODI</matchtype> <matches>287</matches> <innings>279</innings> <notouts>11</notouts> <runsscored>9619</runsscored> <highestscore>172</highestscore> <ballstaken>9922</ballstaken> <sixes>149</sixes> <fours>1000+</fours> <ducks>0</ducks> <fifties>55</fifties> <catches>417</catches> <stumpings>55</stumpings> <hundreds>16</hundreds> <strikerate>96.95</strikerate> <average>35.89</average> </odi-stats> <test-stats> . . . </test-stats> <t20-stats> . . . </t20-stats> <ipl-stats> . . . </ipl-stats> </batting-statistics> <bowling-statistics> <odi-stats> . . . </odi-stats> <test-stats> . . . </test-stats> <t20-stats> . . . </t20-stats> <ipl-stats> . . . </ipl-stats> </bowling-statistics> </player-profile> I am using XmlNodeList list = _document.SelectNodes("/player-profile/batting-statistics/odi-stats"); And then loop this list with foreach as foreach (XmlNode stats in list) { _btMatchType = GetInnerString(stats, "matchtype"); //it returns null string if node not availible . . . . _btAvg = Convert.ToDouble(stats["average"].InnerText); } Even i am loading all files offline, parsing is very slow Is there any good faster way to parse them? Or is it problem with SQL? I am saving all extracted data from XML to database using DataSets, TableAdapters with insert command. I

• Long-running Database Query

thanks for your help thats how i tried to get it into my activity public class MainTabActivity extends TabActivity { private Context context; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.maintabactivity); TabHost mTabHost = getTabHost(); Intent intent1 = new Intent().setClass(this,MapOfLight.class); //Intent intent2 = new Intent().setClass(this,Test.class); //Testactivity //Intent intent2 = new Intent().setClass(this,DetailView.class); //DetailView Intent intent2 = new Intent().setClass(this,ObjectList.class); //ObjectList //Intent intent2 = new Intent().setClass(this,Gallery.class); //Gallery Intent intent3 = new Intent().setClass(this,ContactDetail.class); mTabHost.addTab(mTabHost.newTabSpec("tab_mol").setIndicator(this.getText(R.string.mol), getResources().getDrawable(R.drawable.ic_tab_mol)).setContent(intent1)); mTabHost.addTab(mTabHost.newTabSpec("tab_highlights").setIndicator(this.getText(R.string.highlights),getResources().getDrawable(R.drawable.ic_tab_highlights)).setContent(intent2)); mTabHost.addTab(mTabHost.newTabSpec("tab_contacts").setIndicator(this.getText(R.string.contact),getResources().getDrawable(R.drawable.ic_tab_contact)).setContent(intent3)); mTabHost.setCurrentTab(1); SQLiteDatabase db; DBAdapter dh = null; OpenHelper openHelper = new OpenHelper(this.context); dh = new DBAdapter(this); db = openHelper.getWritableDatabase(); dh.SQL_INSERT_COUNTRY("AT", "Austria", "AUT"); } } i tried it with my country table because it has only 3 columns public class Country { private static String Iso2Count = "iso2_country"; private static String NameCount = "name_country"; private static String FlagCount = "flag_image_url_country"; public static final String TABLE_NAME = "country"; public static final String SQL_CREATE = "CREATE TABLE IF NOT EXISTS " + TABLE_NAME + "(" + Iso2Count + " TEXT not NULL," + NameCount + " TEXT not NULL," + FlagCount + " TEXT not NULL," + "primary key(iso2_country)"; public boolean SQL_INSERT_COUNTRY(String Iso2CountIns, String NameCountIns, String FlagCountIns) { try{ db.execSQL("INSERT INTO " + "country" + "(" + Iso2Count + ", " + NameCount + ", " + FlagCount + ") " + "VALUES ( " + Iso2CountIns + ", " + NameCountIns +", " + FlagCountIns + " )"); return true; } catch (SQLException e) { return false; } } another question is it better to put the insert and select from each table into a separate class, so i have 1 class for each table or put them all into the DBAdapter class?

• XML DB Content Connector unable to accept binary content due to Invalid argument(s) in call oracle.sql.BLOB.setBinaryStream(0L)

  - by sthieme

  Dear Readers, I am working on implementing a custom Document Management System using the Oracle XML DB Content Connector. See the following documentation link for details Oracle XML DB Developer's Guide 11g Release 2 (11.2)Chapter 31 Using Oracle XML DB Content Connectorhttp://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb_jcr.htm especially the following example gave me some trouble to run it successfully Sample Code to Upload Filehttp://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb_jcr.htm#ADXDB5627 I had already succeeded to set some of the properties successfully, i.e. jcr:encoding, jcr:mimeType, ojcr:displayName and ojcr:language. However setting the jcr:data property as described in the example failed consistently, both with the documented input FileStream or with a fixed string. contentNode.setProperty("jcr:data", "mystringvalue"); After some research I found the following Support Note which describes the cause for the issue in the JDBC driver version 11.2.0.1.

• Using Recursive SQL and XML trick to PIVOT(OK, concat) a "Document Folder Structure Relationship" table, works like MySQL GROUP_CONCAT

  - by Kevin Shyr

  I'm in the process of building out a Data Warehouse and encountered this issue along the way.In the environment, there is a table that stores all the folders with the individual level.  For example, if a document is created here:{App Path}\Level 1\Level 2\Level 3\{document}, then the DocumentFolder table would look like this:IDID_ParentFolderName1NULLLevel 121Level 232Level 3To my understanding, the table was built so that:Each proposal can have multiple documents stored at various locationsDifferent users working on the proposal will have different access level to the folder; if one user is assigned access to a folder level, she/he can see all the sub folders and their content.Now we understand from an application point of view why this table was built this way.  But you can quickly see the pain this causes the report writer to show a document link on the report.  I wasn't surprised to find the report query had 5 self outer joins, which is at the mercy of nobody creating a document that is buried 6 levels deep, and not to mention the degradation in performance.With the help of 2 posts (at the end of this post), I was able to come up with this solution:Use recursive SQL to build out the folder pathUse SQL XML trick to concat the strings.Code (a reminder, I built this code in a stored procedure.  If you copy the syntax into a simple query window and execute, you'll get an incorrect syntax error) Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} -- Get all folders and group them by the original DocumentFolderID in PTSDocument table;WITH DocFoldersByDocFolderID(PTSDocumentFolderID_Original, PTSDocumentFolderID_Parent, sDocumentFolder, nLevel)AS (-- first member      SELECT 'PTSDocumentFolderID_Original' = d1.PTSDocumentFolderID            , PTSDocumentFolderID_Parent            , 'sDocumentFolder' = sName            , 'nLevel' = CONVERT(INT, 1000000)      FROM (SELECT DISTINCT PTSDocumentFolderID                  FROM dbo.PTSDocument_DY WITH(READPAST)            ) AS d1            INNER JOIN dbo.PTSDocumentFolder_DY AS df1 WITH(READPAST)                  ON d1.PTSDocumentFolderID = df1.PTSDocumentFolderID      UNION ALL      -- recursive      SELECT ddf1.PTSDocumentFolderID_Original            , df1.PTSDocumentFolderID_Parent            , 'sDocumentFolder' = df1.sName            , 'nLevel' = ddf1.nLevel - 1      FROM dbo.PTSDocumentFolder_DY AS df1 WITH(READPAST)            INNER JOIN DocFoldersByDocFolderID AS ddf1                  ON df1.PTSDocumentFolderID = ddf1.PTSDocumentFolderID_Parent)-- Flatten out folder path, DocFolderSingleByDocFolderID(PTSDocumentFolderID_Original, sDocumentFolder)AS (SELECT dfbdf.PTSDocumentFolderID_Original            , 'sDocumentFolder' = STUFF((SELECT '\' + sDocumentFolder                                         FROM DocFoldersByDocFolderID                                         WHERE (PTSDocumentFolderID_Original = dfbdf.PTSDocumentFolderID_Original)                                         ORDER BY PTSDocumentFolderID_Original, nLevel                                         FOR XML PATH ('')),1,1,'')      FROM DocFoldersByDocFolderID AS dfbdf      GROUP BY dfbdf.PTSDocumentFolderID_Original) And voila, I use the second CTE to join back to my original query (which is now a CTE for Source as we can now use MERGE to do INSERT and UPDATE at the same time).Each part of this solution would not solve the problem by itself because:If I don't use recursion, I cannot build out the path properly.  If I use the XML trick only, then I don't have the originating folder ID info that I need to link to the document.If I don't use the XML trick, then I don't have one row per document to show in the report.I could conceivably do this in the report function, but I'd rather not deal with the beginning or ending backslash and how to attach the document name.PIVOT doesn't do strings and UNPIVOT runs into the same problem as the above.I'm excited that each version of SQL server provides us new tools to solve old problems and/or enables us to solve problems in a more elegant wayThe 2 posts that helped me along:Recursive Queries Using Common Table ExpressionHow to use GROUP BY to concatenate strings in SQL server?

• Benchmark Linq2SQL, Subsonic2, Subsonic3 - Any other ideas to make them faster ?

  - by Aristos

  I am working with Subsonic 2 more than 3 years now... After Linq appears and then Subsonic 3, I start thinking about moving to the new Linq futures that are connected to sql. I must say that I start move and port my subsonic 2 with SubSonic 3, and very soon I discover that the speed was so slow thats I didn't believe it - and starts all that tests. Then I test Linq2Sql and see also a delay - compare it with Subsonic 2. My question here is, especial for the linq2sql, and the up-coming dotnet version 4, what else can I do to speed it up ? What else on linq2sql settings, or classes, not on this code that I have used for my messures I place here the project that I make the tests, also the screen shots of the results. How I make the tests - and the accurate of my measures. I use only for my question Google chrome, because its difficult for me to show here a lot of other measures that I have done with more complex programs. This is the most simple one, I just measure the Data Read. How can I prove that. I make a simple Thread.Sleep(10 seconds) and see if I see that 10 seconds on Google Chrome Measure, and yes I see it. here are more test with this Sleep thead to see whats actually Chrome gives. 10 seconds delay 100 ms delay Zero delay There is only a small 15ms thats get on messure, is so small compare it with the rest of my tests that I do not care about. So what I measure I measure just the data read via each method - did not count the data or database delay, or any disk read or anything like that. Later on the image with the result I show that no disk activity exist on the measures See this image to see what really I measure and if this is correct Why I chose this kind of test Its simple, it's real, and it's near my real problem that I found the delay of subsonic 3 in real program with real data. Now lets tests the dals Start by see this image I have 4-5 calls on every method, the one after the other. The results are. For a loop of 100 times, ask for 5 Rows, one not exist, approximatively.. Simple adonet:81ms SubSonic 2 :210ms linq2sql :1.70sec linq2sql using CompiledQuery.Compile :239ms Subsonic 3 :15.00sec (wow - extreme slow) The project http://www.planethost.gr/DalSpeedTests.rar Can any one confirm this benchmark, or make any optimizations to help me out ? Other tests Some one publish here this link http://ormbattle.net/ (and then remove it - don not know why) In this page you can find a really useful advanced tests for all, except subsonic 2 and subsonic 3 that I have here ! Optimizing What I really ask here is if some one can now any trick how to optimize the DALs, not by changing the test code, but by changing the code and the settings on each dal. For example... Optimizing Linq2SQL I start search how to optimize Linq2sql and found this article, and maybe more exist. Finally I make the tricks from that page to run, and optimize the code using them all. The speed was near 1.50sec from 1.70.... big improvement, but still slow. Then I found a different way - same idea article, and wow ! the speed is blow up. Using this trick with CompiledQuery.Compile, the time from 1.5sec is now 239ms. Here is the code for the precompiled... Func<DataClassesDataContext, int, IQueryable<Product>> compiledQuery = CompiledQuery.Compile((DataClassesDataContext meta, int IdToFind) => (from myData in meta.Products where myData.ProductID.Equals(IdToFind) select myData)); StringBuilder Test = new StringBuilder(); int[] MiaSeira = { 5, 6, 10, 100, 7 }; using (DataClassesDataContext context = new DataClassesDataContext()) { context.ObjectTrackingEnabled = false; for (int i = 0; i < 100; i++) { foreach (int EnaID in MiaSeira) { var oFindThat2P = compiledQuery(context, EnaID); foreach (Product One in oFindThat2P) { Test.Append("<br />"); Test.Append(One.ProductName); } } } } Optimizing SubSonic 3 and problems I make many performance profiling, and start change the one after the other and the speed is better but still too slow. I post them on subsonic group but they ignore the problem, they say that everything is fast... Here is some capture of my profiling and delay points inside subsonic source code I have end up that subsonic3 make more call on the structure of the database rather than on data itself. Needs to reconsider the hole way of asking for data, and follow the subsonic2 idea if this is possible. Try to make precompile to subsonic 3 like I did in linq2Sql but fail for the moment... Optimizing SubSonic 2 After I discover that subsonic 3 is extreme slow, I start my checks on subsonic 2 - that I have never done before believing that is fast. (and it is) So its come up with some points that can be faster. For example there are many loops like this ones that actually is slow because of string manipulation and compares inside the loop. I must say to you that this code called million of times ! on a period of few minutes ! of data asking from the program. On small amount of tables and small fields maybe this is not a big think for some people, but on large amount of tables, the delay is even more. So I decide and optimize the subsonic 2 by my self, by replacing the string compares, with number compares! Simple. I do that almost on every point that profiler say that is slow. I change also all small points that can be even a little faster, and disable some not so used thinks. The results, 5% faster on NorthWind database, near 20% faster on my database with 250 tables. That is count with 500ms less in 10 seconds process on northwind, 100ms faster on my database on 500ms process time. I do not have captures to show you for that because I have made them with different code, different time, and track them down on paper. Anyway this is my story and my question on all that, what else do you know to make them even faster... For this measures I have use Subsonic 2.2 optimized by me, Subsonic 3.0.0.3 a little optimized by me, and Dot.Net 3.5

• Configuration Error ASP.NET password format specified is invalid

  - by salvationishere

  I am getting the above error in IIS 6.0 now when I browse my C# / SQL web application. This was built in VS 2008 and SS 2008 on a 32-bit XP OS. The application was working before I added Login controls to it. However, this is my first time configuring Login/password controls so I am probably missing something really basic. This error doesn't happen until I try to login. Here are the details of my error from IIS; I get the same error in VS: Parser Error Message: Password format specified is invalid.

The Network Service account has SELECT, EXECUTE, INSERT, UPDATE access to this database. But one problem I see is that all of the tables in this database are empty except for aspnet_SchemaVersions, which just has 2 records (common and membership). Is this right? I added users and roles via ASP.NET Configuration wizard, and I believe I set this up correctly since I followed the Microsoft tutorial at http://msdn.microsoft.com/en-us/library/ms998347.aspx. One other problem I see from VS is after adding content to my Page_Load on my initial login Password.aspx.cs file, I'm getting an invalid cast problem below. I googled this problem also but the solutions I saw confused me even more. The Page_Load section I added is: protected void Page_Load(object sender, EventArgs e) { Response.Write("Hello, " + Server.HtmlEncode(User.Identity.Name)); FormsIdentity id = (FormsIdentity)User.Identity; FormsAuthenticationTicket ticket = id.Ticket; Response.Write("<p/>TicketName: " + ticket.Name); Response.Write("<br/>Cookie Path: " + ticket.CookiePath); Response.Write("<br/>Ticket Expiration: " + ticket.Expiration.ToString()); Response.Write("<br/>Expired: " + ticket.Expired.ToString()); Response.Write("<br/>Persistent: " + ticket.IsPersistent.ToString()); Response.Write("<br/>IssueDate: " + ticket.IssueDate.ToString()); Response.Write("<br/>UserData: " + ticket.UserData); Response.Write("<br/>Version: " + ticket.Version.ToString()); } And the VS exception I'm getting: System.InvalidCastException was unhandled by user code Message="Unable to cast object of type 'System.Security.Principal.GenericIdentity' to type 'System.Web.Security.FormsIdentity'."

• BizTalk 2009 - Installing BizTalk Server 2009 on XP for Development

  - by StuartBrierley

  At my previous employer, when developing for BizTalk Server 2004 using Visual Studio 2003, we made use of separate development and deployment environments; developing in Visual Studio on our client PCs and then deploying to a seperate shared BizTalk 2004 Server from there.  This server was part of a multi-server Standard BizTalk environment comprising of separate BizTalk Server 2004 and SQL Server 2000 servers.  This environment was implemented a number of years ago by an outside consulting company, and while it worked it did occasionally cause contention issues with three developers deploying to the same server to carry out unit testing! Now that I am making the design and implementation decisions about the environment that BizTalk will be developed in and deployed to, I have chosen to create a single "server" installation on my development PC, installling SQL Server 2008, Visual Studio 2008 and BizTalk Server 2009 on a single system.  The client PC in use is actually a MacBook Pro running Windows XP; not the most powerful of systems for high volume processing but it should be powerful enough to allow development and initial unit testing to take place. I did not need to, and so chose not to, install all of the components detailed in the Microsoft guide for installing BizTalk 2009 on Windows XP but I did follow the basics of the procedures detailed within.  Outlined below are the highlights of this process and any details of what choices I made.   Install IIS I had previsouly installed Windows XP, including all current service packs and critical updates.  At the time of installation this included Service Pack 3, the .Net Framework 3.5 and MS Windows Installer 3.1.  Having a running XP system, my first step was to install IIS - this is quite straightforward and posed no difficulties. Install Visual Studio 2008 The next step for me was to install Visual Studio 2008.  Making sure to select a custom installation is crucial at this point, as you need to make sure that you deselect SQL Server 2005 Express Edition as it can cause the BizTalk installation to fail.  The installation guide suggests that you only select Visual C# when selecting features to install, but  I decided that due to some legacy systems I have code for that I would also select the VB and ASP options. Visual Studio 2008 Service Pack 1 Following the completion of the installation of Visual Studio itself you should then install the Visual Studio 2008 Service Pack 1. SQL Server 2008 Standard Edition The next step before intalling BizTalk Server 2009 itself is to install SQL Server 2008 Standard Edition. On the feature selection screen make sure that you select the follwoing options: Database Engine Services SQL Server Replication Full-Text Search Analysis Services Reporting Services Business Intelligence Development Studio Client Tools Connectivity Integration Services Management Tools Basic and Complete Use the default instance and the same accounts for all SQL server instances - in my case I used the Network Service and Local Service accounts for the two sets of accounts. On the database engine configuration screen I selected windows authentication and added the current user, adding the same user again on the Analysis services Configuration screen.  All other screens were left on the default settings. The SQL Server 2008 installation also included the installation of hotfix for XP KB942288-v3, the Windows Installer 4.5 Redistributable. System Configuration At this stage I took a moment to disable the SQL Server shared memory protocol and enable the Named Pipes and TCP/IP protocols.  These can be found in the SQL Server Configuration Manager > SQL Server Network Configuration > Protocols for MSSQLServer.  I also made sure that the DTC settings were configured correctley.   BizTalk Server 2009 The penultimate step is to install BizTalk Server 2009 Standard Edition. I had previsouly downloaded the redistributable prerequisites as a CAB file so was able to make use of this when carrying out the installation. When selecting which components to install I selected: Server Runtime BizTalk EDI/AS2 Runtime WCF Adapter Runtime Portal Components Administrative Tools WFC Administartion Tools Developer Tools and SDK, Enterprise SSO Administration Module Enterprise SSO Master Secret Server Business Rules Components BAM Alert Provider BAM Client BAM Eventing Once installation has completed clear the launch BizTalk Server Configuration check box and select finish. Verify the Installation Before configuring BizTalk Server it is a good idea to check that BizTalk Server 2009 is installed and that SQL Server 2008 has started correctly.  The easiest way to verify the BizTalk installation is check the Programs and Features in Control panel.  Check that SQL is started by looking in the SQL Server Configuration Manager. Configure BizTalk Server 2009 Finally we are ready to configure BizTalk Server 2009.  To start this I opted for a custom configuration that allowed me to choose in more detail the settings to be used. For all databases I selected the local server and default database names. For all Accounts I used a local account that had been created specifically for the BizTalk Services. For all windows groups I allowed the configuration wizard to create the default local groups. The configuration wizard then ran:   Upon completion you will be presented with a screen detailing the success or failure of the configuration.  If your configuration failed you will need to sort out the issues and try again (it is possible to save the configuration settings for later use if you want too - except passwords of course!).  If you see lots of nice green ticks - congratulations BizTalk Server 2009 on XP is now installed and configured ready for development.

• Expression Tree

  - by nettguy

  My understanding of expression tree is : Expression trees are in-memory representation of expression like arithmetic or boolean expression.The expressions are stored into the parsed tree.so we can easily transalate into any other language. Linq to SQL uses expression tree.Normally in LINQ to SQL query the compiler translates it into parsed expression trees.These are passed to Sql Server as T-SQL Statements.The Sql server executes the T-SQL query and sends down the result back.That is why when you execute LINQ to SQL you gets IQueryable<T> not IEnumetrable<T>.Because IQuerybale contains public IQueryable:IEnumerable { Type Element {get;} Expression Expression {get;} IQueryaleProvider Provider {get;} } Questions : Microsoft uses Expression trees to play with LINQ-to-Sql.What are the different ways can i use expression trees to boost my code. Apart from LINQ to SQL,Linq to amazon ,who used expression trees in their applications? Linq to Object return IEnumerable,Linq to SQL return IQueryable ,What does LINQ to XML return?

• Expression Tree : C#

  - by nettguy

  My understanding of expression tree is : Expression trees are in-memory representation of expression like arithmetic or boolean expression.The expressions are stored into the parsed tree.so we can easily transalate into any other language. Linq to SQL uses expression tree.Normally when our LINQ to SQL query compiler translates it to parsed expression trees.These are passed to Sql Server as T-SQL Statements.The Sql server executes the T-SQL query and sends down the result back.That is why when you execute LINQ to SQL you gets IQueryable<T> not IEnumetrable<T>.Because IQuerybale contains public IQueryable:IEnumerable { Type Element {get;} Expression Expression {get;} IQueryaleProvider Provider {get;} } Questions : Microsoft uses Expression trees to play with LINQ-to-Sql.What are the different ways can i use expression trees to boost my code. Apart from LINQ to SQL,Linq to amazon ,who used expression trees in their applications? Linq to Object return IEnumerable,Linq to SQL return IQueryable ,What does LINQ to XML return?

• WCF Bidirectional serialization fails

  - by Gena Verdel

  I'm trying to take advantage of Bidirectional serialization of some relational Linq-2-Sql generated entity classes. When using Unidirectional option everything works just fine, bu the moment I add IsReferenceType=true, objects fail to get transported over the tcp binding.

  Please see my below(SubjectDetailsDao.java) code of addZoneToDb method. My debugger is nicely running upto ** session.getTransaction().commit();** code. but after that debugger stops,I do not know why it stops after that line? .And because of this i am unable to insert my data into my database table.

• Differences Between NHibernate and Entity Framework

  - by Ricardo Peres

  Introduction NHibernate and Entity Framework are two of the most popular O/RM frameworks on the .NET world. Although they share some functionality, there are some aspects on which they are quite different. This post will describe this differences and will hopefully help you get started with the one you know less. Mind you, this is a personal selection of features to compare, it is by no way an exhaustive list. History First, a bit of history. NHibernate is an open-source project that was first ported from Java’s venerable Hibernate framework, one of the first O/RM frameworks, but nowadays it is not tied to it, for example, it has .NET specific features, and has evolved in different ways from those of its Java counterpart. Current version is 3.3, with 3.4 on the horizon. It currently targets .NET 3.5, but can be used as well in .NET 4, it only makes no use of any of its specific functionality. You can find its home page at NHForge. Entity Framework 1 came out with .NET 3.5 and is now on its second major version, despite being version 4. Code First sits on top of it and but came separately and will also continue to be released out of line with major .NET distributions. It is currently on version 4.3.1 and version 5 will be released together with .NET Framework 4.5. All versions will target the current version of .NET, at the time of their release. Its home location is located at MSDN. Architecture In NHibernate, there is a separation between the Unit of Work and the configuration and model instances. You start off by creating a Configuration object, where you specify all global NHibernate settings such as the database and dialect to use, the batch sizes, the mappings, etc, then you build an ISessionFactory from it. The ISessionFactory holds model and metadata that is tied to a particular database and to the settings that came from the Configuration object, and, there will typically be only one instance of each in a process. Finally, you create instances of ISession from the ISessionFactory, which is the NHibernate representation of the Unit of Work and Identity Map. This is a lightweight object, it basically opens and closes a database connection as required and keeps track of the entities associated with it. ISession objects are cheap to create and dispose, because all of the model complexity is stored in the ISessionFactory and Configuration objects. As for Entity Framework, the ObjectContext/DbContext holds the configuration, model and acts as the Unit of Work, holding references to all of the known entity instances. This class is therefore not lightweight as its NHibernate counterpart and it is not uncommon to see examples where an instance is cached on a field. Mappings Both NHibernate and Entity Framework (Code First) support the use of POCOs to represent entities, no base classes are required (or even possible, in the case of NHibernate). As for mapping to and from the database, NHibernate supports three types of mappings: XML-based, which have the advantage of not tying the entity classes to a particular O/RM; the XML files can be deployed as files on the file system or as embedded resources in an assembly; Attribute-based, for keeping both the entities and database details on the same place at the expense of polluting the entity classes with NHibernate-specific attributes; Strongly-typed code-based, which allows dynamic creation of the model and strongly typing it, so that if, for example, a property name changes, the mapping will also be updated. Entity Framework can use: Attribute-based (although attributes cannot express all of the available possibilities – for example, cascading); Strongly-typed code mappings. Database Support With NHibernate you can use mostly any database you want, including: SQL Server; SQL Server Compact; SQL Server Azure; Oracle; DB2; PostgreSQL; MySQL; Sybase Adaptive Server/SQL Anywhere; Firebird; SQLLite; Informix; Any through OLE DB; Any through ODBC. Out of the box, Entity Framework only supports SQL Server, but a number of providers exist, both free and commercial, for some of the most used databases, such as Oracle and MySQL. See a list here. Inheritance Strategies Both NHibernate and Entity Framework support the three canonical inheritance strategies: Table Per Type Hierarchy (Single Table Inheritance), Table Per Type (Class Table Inheritance) and Table Per Concrete Type (Concrete Table Inheritance). Associations Regarding associations, both support one to one, one to many and many to many. However, NHibernate offers far more collection types: Bags of entities or values: unordered, possibly with duplicates; Lists of entities or values: ordered, indexed by a number column; Maps of entities or values: indexed by either an entity or any value; Sets of entities or values: unordered, no duplicates; Arrays of entities or values: indexed, immutable. Querying NHibernate exposes several querying APIs: LINQ is probably the most used nowadays, and really does not need to be introduced; Hibernate Query Language (HQL) is a database-agnostic, object-oriented SQL-alike language that exists since NHibernate’s creation and still offers the most advanced querying possibilities; well suited for dynamic queries, even if using string concatenation; Criteria API is an implementation of the Query Object pattern where you create a semi-abstract conceptual representation of the query you wish to execute by means of a class model; also a good choice for dynamic querying; Query Over offers a similar API to Criteria, but using strongly-typed LINQ expressions instead of strings; for this, although more refactor-friendlier that Criteria, it is also less suited for dynamic queries; SQL, including stored procedures, can also be used; Integration with Lucene.NET indexer is available. As for Entity Framework: LINQ to Entities is fully supported, and its implementation is considered very complete; it is the API of choice for most developers; Entity-SQL, HQL’s counterpart, is also an object-oriented, database-independent querying language that can be used for dynamic queries; SQL, of course, is also supported. Caching Both NHibernate and Entity Framework, of course, feature first-level cache. NHibernate also supports a second-level cache, that can be used among multiple ISessionFactorys, even in different processes/machines: Hashtable (in-memory); SysCache (uses ASP.NET as the cache provider); SysCache2 (same as above but with support for SQL Server SQL Dependencies); Prevalence; SharedCache; Memcached; Redis; NCache; Appfabric Caching. Out of the box, Entity Framework does not have any second-level cache mechanism, however, there are some public samples that show how we can add this. ID Generators NHibernate supports different ID generation strategies, coming from the database and otherwise: Identity (for SQL Server, MySQL, and databases who support identity columns); Sequence (for Oracle, PostgreSQL, and others who support sequences); Trigger-based; HiLo; Sequence HiLo (for databases that support sequences); Several GUID flavors, both in GUID as well as in string format; Increment (for single-user uses); Assigned (must know what you’re doing); Sequence-style (either uses an actual sequence or a single-column table); Table of ids; Pooled (similar to HiLo but stores high values in a table); Native (uses whatever mechanism the current database supports, identity or sequence). Entity Framework only supports: Identity generation; GUIDs; Assigned values. Properties NHibernate supports properties of entity types (one to one or many to one), collections (one to many or many to many) as well as scalars and enumerations. It offers a mechanism for having complex property types generated from the database, which even include support for querying. It also supports properties originated from SQL formulas. Entity Framework only supports scalars, entity types and collections. Enumerations support will come in the next version. Events and Interception NHibernate has a very rich event model, that exposes more than 20 events, either for synchronous pre-execution or asynchronous post-execution, including: Pre/Post-Load; Pre/Post-Delete; Pre/Post-Insert; Pre/Post-Update; Pre/Post-Flush. It also features interception of class instancing and SQL generation. As for Entity Framework, only two events exist: ObjectMaterialized (after loading an entity from the database); SavingChanges (before saving changes, which include deleting, inserting and updating). Tracking Changes For NHibernate as well as Entity Framework, all changes are tracked by their respective Unit of Work implementation. Entities can be attached and detached to it, Entity Framework does, however, also support self-tracking entities. Optimistic Concurrency Control NHibernate supports all of the imaginable scenarios: SQL Server’s ROWVERSION; Oracle’s ORA_ROWSCN; A column containing date and time; A column containing a version number; All/dirty columns comparison. Entity Framework is more focused on Entity Framework, so it only supports: SQL Server’s ROWVERSION; Comparing all/some columns. Batching NHibernate has full support for insertion batching, but only if the ID generator in use is not database-based (for example, it cannot be used with Identity), whereas Entity Framework has no batching at all. Cascading Both support cascading for collections and associations: when an entity is deleted, their conceptual children are also deleted. NHibernate also offers the possibility to set the foreign key column on children to NULL instead of removing them. Flushing Changes NHibernate’s ISession has a FlushMode property that can have the following values: Auto: changes are sent to the database when necessary, for example, if there are dirty instances of an entity type, and a query is performed against this entity type, or if the ISession is being disposed; Commit: changes are sent when committing the current transaction; Never: changes are only sent when explicitly calling Flush(). As for Entity Framework, changes have to be explicitly sent through a call to AcceptAllChanges()/SaveChanges(). Lazy Loading NHibernate supports lazy loading for Associated entities (one to one, many to one); Collections (one to many, many to many); Scalar properties (thing of BLOBs or CLOBs). Entity Framework only supports lazy loading for: Associated entities; Collections. Generating and Updating the Database Both NHibernate and Entity Framework Code First (with the Migrations API) allow creating the database model from the mapping and updating it if the mapping changes. Extensibility As you can guess, NHibernate is far more extensible than Entity Framework. Basically, everything can be extended, from ID generation, to LINQ to SQL transformation, HQL native SQL support, custom column types, custom association collections, SQL generation, supported databases, etc. With Entity Framework your options are more limited, at least, because practically no information exists as to what can be extended/changed. It features a provider model that can be extended to support any database. Integration With Other Microsoft APIs and Tools When it comes to integration with Microsoft technologies, it will come as no surprise that Entity Framework offers the best support. For example, the following technologies are fully supported: ASP.NET (through the EntityDataSource); ASP.NET Dynamic Data; WCF Data Services; WCF RIA Services; Visual Studio (through the integrated designer). Documentation This is another point where Entity Framework is superior: NHibernate lacks, for starters, an up to date API reference synchronized with its current version. It does have a community mailing list, blogs and wikis, although not much used. Entity Framework has a number of resources on MSDN and, of course, several forums and discussion groups exist. Conclusion Like I said, this is a personal list. I may come as a surprise to some that Entity Framework is so behind NHibernate in so many aspects, but it is true that NHibernate is much older and, due to its open-source nature, is not tied to product-specific timeframes and can thus evolve much more rapidly. I do like both, and I chose whichever is best for the job I have at hands. I am looking forward to the changes in EF5 which will add significant value to an already interesting product. So, what do you think? Did I forget anything important or is there anything else worth talking about? Looking forward for your comments!
