  • Organize code in Chef: libraries, classes and resources

    - by ColOfAbRiX
    I am new to both Chef and Ruby and I am implementing some scripts to learn them. Now I am facing the problem of how to organize my code: I have created a class in the library directory and I have used a custom namespace to maintain order. This is a simplified example of my file: # ~/chef-repo/cookbooks/mytest/libraries/MyTools.rb module Chef::Recipe::EP class MyTools def self.print_something( text ) puts "This is my text: #{text}" end def self.copy_file( dir, file ) cookbook_file "#{dir}/#{file}" do source "#{dir}/#{file}" end end end end From my recipe I call both methods: # ~/chef-repo/cookbooks/mytest/recipes/default.rb EP::MyTools.print_something "Hello World!" EP::MyTools.copy_file "/etc", "passwd" print_something works fine, but with copy_file I get this error: undefined method `cookbook_file' for Chef::Recipe::EP::FileTools:Class It's clear to me that I don't know how to create libraries in Chef or I don't know some basic assumptions. Can anyone help me, please? I am looking for a solution of this problem (organize my code, libraries, use resources in classes) or, better, a good Chef documentation as I find the documentation very deficient in clarity and disorganized so that research through it is a pain.

  • Greater than or equal check when using Group Policy Preferences and Item Level Targeting in the Registry

    - by edusysadmin
    I'm implementing some screen saver configurations via Group Policy Preferences (on Win7 Enterprise x64 desktops). The desired configuration is to have users be able to adjust their screen saver and screen saver time out, but not allow them to select non screen saver or a time out higher than 45min. I've found a great write-up for configuration of the screen saver (link) but cannot find a way to configure the time out. I cannot find a way to have the item level targeting compare the reg key HKCU\Control Panel\Desktop\ScreenSaveTimeOut value and force an over-write of the key if configured above 45min/2700seconds. Anyone else tried something like this or found a means to do this?

  • Grails SSL TOMCAT

    - by user974459
    I'm implementing grails with SSL and deployed to tomcat 7.0. I have used spring security plugin for SSL. In tomcat, I added <Connector port="80" protocol="HTTP/1.1" connectionTimeout="200000000" redirectPort="443" /> <Connector port="8443" protocol="HTTP/1.1" connectionTimeout="200000000" redirectPort="443" /> <Connector port="443" maxThreads="200" scheme="https" secure="true" SSLEnabled="true" keystoreFile="${user.home}/.keystore" keystorePass="123456" clientAuth="false" sslProtocol="TLS"/> if I type https://localhost is ok. But my app doesn't work.

  • Is it possible to put only the boot partition on a usb stick?

    - by Steve V.
    I've been looking at system encryption with ArchLinux and i think I have it pretty much figured out but I have a question about the /boot partition. Once the system is booted up is it possible to unmount the /boot partition and allow the system to continue to run? My thought was to install /boot to a USB stick since it can't be left encrypted and then boot from the USB stick which would boot up the encrypted hard disk. Then I can take the USB key out and just use the system as normal. The reason I want to do this is because if an attacker was able to get physical access to the machine they could modify the /boot partition with a keystroke logger and steal the key and if they already had a copy of the encrypted data they could just sit back and wait for the key. I guess I could come up with a system of verifying that the boot has been untouched at each startup. Has this been done before? Any guidance for implementing it on my own?

  • Cannot assign multi-line values to CustomAttributes with Set-Mailbox

    - by Biglig
    A colleague is implementing an application that generates signatures and publishes them to Outlook. It would be useful to him if I could store a multi-line string for each user in Active-Directory. Using one of the Custom-Attributes seems obvious, but if I try set-mailbox biglig -CustomAtribute1 "First Line``r``n Second Line" then CustomAttribute1 gets set to "FirstLineSecondLine" and looses the breaks. However, the same syntax works fine when I set e.g. StreetAddress or Notes. Of course, those are changed with set-user rather than set-mailbox. According to Technet's reference for set-user and set-mailbox, The CustomAttributes, StreetAddress, and Notes all take a system.string as their value. Is it just the case that some attributes accept multi-line strings and some don't? If so, can anyone suggest a workaround?

  • Windows 2012 Master & Ubuntu Bind 9 Slave & SOA

    - by RecentCoin
    I'm kinda like the maid... I don't do Windows. But thanks to new things we're implementing, I'm now attempting replicating a single zone from our AD cluster. We had this working just fine but someone had to "adjust" it. That broke the replication completely. We've gotten that restarted but now a different DC is showing as the SOA. Does it matter which of the domain controllers is listed as the SOA? The contents of the zone file appear to be correct. Part of me says "Good enough. Leave it be." but the rest of me doesn't want a 3AM phone call. So does anyone know if it matters which DC is listed as the SOA?

  • Controlling access to my API using SSH public key (not SSL)

    - by tharrison
    I have the challenge of implementing an API to be consumed by relatively non-technical clients -- pasting some sample code into their WordPress or homegrown PHP site is probably as much as we can ask. Asking them to install SSL on their servers ain't happening. So I am seeking a simple yet secure way to authenticate API clients. OAuth is the obvious solution, but I don't think it passes the "simple" test. Adding a client id and hashed secret as a parameter to the requests is closer -- it's not hard to do md5($secret . $client_id) or whatever the php would be. It seems to me that if client requests could use the same approach as SSH public keys (client gives us a key from their server(s) there should be some existing magic to make all of the subsequent transactions transparently work just as regular HTTP API requests. I am still working this out (obviously :-), so if I am being an idiot, it would be nice to know why. Thanks!

  • Rejecting new HTTP requests when server reaches a certain throughput

    - by user56221
    I have a requirement to run an HTTP server that rejects new HTTP requests (with a 503, or similar) when the global transfer rate of current HTTP responses exceeds a certain level. For example, if the web server is transferring at 98Mbps, and a new HTTP request arrives, we would want to reject this (as we couldn't guarantee a good speed). I've had a look at mod_cband for Apache, limit_req for nginx, and lighttpd's rate limiting features, but none of them seem to handle my (rather contrived, granted) use case. I should add that I'm open to using pretty much any web server, and am open to implementing this in iptables rules if someone can craft such a rule! (Refusing the TCP connection is fine, it doesn't have to respond with an HTTP 503). Any suggestions?

  • Can I get some help on a javascript project?

    - by HenryOrrin
    I'm learning javascript and I thought it would be fun to build a "simple" calculator. I spent a few hours coding, and implementing the functions, but it only works partially. Can one of you look at my code and try and figure out what's wrong? The Calculator.zip Here's some explanation of the issues: the add(), subtract(), multiply(), and divide() methods work partially, not at all, or don't do as they're supposed to.. sometimes the 0 wont clear when the replaceDisplay() method evaluates the screen. If it helps, I'm also using jquery, so keep that in mind. Thank you!

  • PuTTY: how to properly emulate -t option

    - by John Sonderson
    On Linux the ssh command has a -t option whose man page reads: Force pseudo-tty allocation. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g. when implementing menu services. Multiple -t options force tty allocate, even if ssh has no local tty. I would like to use this same option with PuTTY on Windows. In particular, I can see that PuTTY has a bunch of options under: Category - Connection - SSH - TTY and suspect it might be possible to achieve the same behavior via some of the (NUMEROUS!) settings found on this screen. Anyone know how to configure the following command: ssh -t USER,[email protected] create Thanks!

  • How do you host images using Windows Server so that they are accessible over the internet? [closed]

    - by nairware
    I was trying to figure out a way to host images (picture images, not disk images) such that they are accessible over the internet via URLs--in a way similar to a web service like Photobucket or ImageShack. I have a whole bunch of Windows Servers (Windows Server 2008 R2) available in the cloud. Instead of hosting images using Photobucket or ImageShack, I wanted to host this images directly on my own Windows cloud. This could be really complicated or really simple. I have no idea, as I know very little about IIS 6 (which is what I am using) or web servers. If this is too broad of a question (as there are probably multiple ways of implementing this), is there at least some guide or documentation of how someone else has setup image hosting? Perhaps a step-by-step guide of at least one way to do it?

  • RAID 10 over RAID 5 when using SSDs

    - by root
    I am considering implementing an iSCSI shared storage array using SATA SSDs instead of the 15k RPM SAS drives we normally purchase. We normally use RAID 10 because of spindle contention with the random IO produced by virtualized workloads. I was wondering if we could switch to RAID 5 or RAID 6 to have more usuable space now that spindle contention is less of an issue. A question in my mind is how much overhead there is from the controller calculating parity. I am aware that this configuration will not allow TRIM to function. Our current workloads are running on a Dell H800 with a 24 bay external enclosure.

  • SQL SERVER – 2011 – Wait Type – Day 25 of 28

    - by pinaldave
    Since the beginning of the series, I have been getting the following question again and again: “What are the changes in SQL Server 2011 – Denali with respect to Wait Types?” SQL Server 2011 – Denali is yet to be released, and making statements on the subject will be inappropriate. Denali CTP1 has been released so I suggest that all of you download the same and experiment on it. I quickly compared the wait stats of SQL Server 2008 R2 and Denali (CTP1) and found the following changes: Wait Types Exists in SQL Server 2008 R2 and Not Exists in SQL Server 2011 “Denali” SOS_RESERVEDMEMBLOCKLIST SOS_LOCALALLOCATORLIST QUERY_WAIT_ERRHDL_SERVICE QUERY_ERRHDL_SERVICE_DONE XE_PACKAGE_LOCK_BACKOFF Wait Types Exists in SQL Server 2011 and Not Exists in SQL Server 2008 SLEEP_MASTERMDREADY SOS_MEMORY_TOPLEVELBLOCKALLOCATOR SOS_PHYS_PAGE_CACHE FILESTREAM_WORKITEM_QUEUE FILESTREAM_FILE_OBJECT FILESTREAM_FCB FILESTREAM_CACHE XE_CALLBACK_LIST PWAIT_MD_RELATION_CACHE PWAIT_MD_SERVER_CACHE PWAIT_MD_LOGIN_STATS DISPATCHER_PRIORITY_QUEUE_SEMAPHORE FT_PROPERTYLIST_CACHE SECURITY_KEYRING_RWLOCK BROKER_TRANSMISSION_WORK BROKER_TRANSMISSION_OBJECT BROKER_TRANSMISSION_TABLE BROKER_DISPATCHER BROKER_FORWARDER UCS_MANAGER UCS_TRANSPORT UCS_MEMORY_NOTIFICATION UCS_ENDPOINT_CHANGE UCS_TRANSPORT_STREAM_CHANGE QUERY_TASK_ENQUEUE_MUTEX DBCC_SCALE_OUT_EXPR_CACHE PWAIT_ALL_COMPONENTS_INITIALIZED PREEMPTIVE_SP_SERVER_DIAGNOSTICS SP_SERVER_DIAGNOSTICS_SLEEP SP_SERVER_DIAGNOSTICS_INIT_MUTEX AM_INDBUILD_ALLOCATION QRY_PARALLEL_THREAD_MUTEX FT_MASTER_MERGE_COORDINATOR PWAIT_RESOURCE_SEMAPHORE_FT_PARALLEL_QUERY_SYNC REDO_THREAD_PENDING_WORK REDO_THREAD_SYNC COUNTRECOVERYMGR HADR_DB_COMMAND HADR_TRANSPORT_SESSION HADR_CLUSAPI_CALL PWAIT_HADR_CHANGE_NOTIFIER_TERMINATION_SYNC PWAIT_HADR_ACTION_COMPLETED PWAIT_HADR_OFFLINE_COMPLETED PWAIT_HADR_ONLINE_COMPLETED PWAIT_HADR_FORCEFAILOVER_COMPLETED PWAIT_HADR_WORKITEM_COMPLETED HADR_WORK_POOL HADR_WORK_QUEUE HADR_LOGCAPTURE_SYNC LOGPOOL_CACHESIZE LOGPOOL_FREEPOOLS LOGPOOL_REPLACEMENTSET LOGPOOL_CONSUMERSET LOGPOOL_MGRSET LOGPOOL_CONSUMER LOGPOOLREFCOUNTEDOBJECT_REFDONE HADR_SYNC_COMMIT HADR_AG_MUTEX PWAIT_SECURITY_CACHE_INVALIDATION PWAIT_HADR_SERVER_READY_CONNECTIONS HADR_FILESTREAM_MANAGER HADR_FILESTREAM_BLOCK_FLUSH HADR_FILESTREAM_IOMGR XDES_HISTORY XDES_SNAPSHOT HADR_FILESTREAM_IOMGR_IOCOMPLETION UCS_SESSION_REGISTRATION ENABLE_EMPTY_VERSIONING HADR_DB_OP_START_SYNC HADR_DB_OP_COMPLETION_SYNC HADR_LOGPROGRESS_SYNC HADR_TRANSPORT_DBRLIST HADR_FAILOVER_PARTNER XDESTSVERMGR GHOSTCLEANUPSYNCMGR HADR_AR_UNLOAD_COMPLETED HADR_PARTNER_SYNC HADR_DBSTATECHANGE_SYNC We already know that Wait Types and Wait Stats are going to be the next big thing in the next version of SQL Server.

All the discussion of Wait Stats in this blog is generic and varies from system to system. It is recommended that you test this on a development server before implementing it to a production server.

  • How do I make an on-screen HUD in libgdx?

    - by Devin Carless
    I'm new to libgdx, and I am finding I am getting stumped by the simplest of things. It seems to want me to do things a specific way, but the documentation won't tell me what that is. I want to make a very simple 2d game in which the player controls a spaceship. The mouse wheel will zoom in and out, and information and controls are displayed on the screen. But I can't seem to make the mouse wheel NOT zoom the UI. I've tried futzing with the projection matrices in between Here's my (current) code: public class PlayStage extends Stage { ... public void draw() { // tell the camera to update its matrices. camera.update(); // tell the SpriteBatch to render in the // coordinate system specified by the camera. spriteBatch.setProjectionMatrix(camera.combined); spriteBatch.begin(); aButton.draw(spriteBatch, 1F); playerShip.draw(spriteBatch, 1F); spriteBatch.end(); } } camera.zoom is set by scrolled(int amount). I've tried about a dozen variations on the theme of changing the camera's projection matrix after the button is drawn but before the ship is, but no matter what I do, the same things happen to both the button and the ship. So: What is the usual libgdx way of implementing an on-screen UI that isn't transformed by the camera's projection matrix/zoom?

  • LinqPad with Azure Table Storage

    - by Sarang
    LinqPad as we all know has been a wonderful tool for running ad-hoc queries. With Windows Azure Table storage in picture LinqPad was no longer in picture and we shifted focus to Cloud Storage Studio only to realize the limited and strange querying capabilities of CSS. With some tweaking to Linqpad we can get the comfortable old shoe of ad-hoc queries with LinqPad in the Windows Azure Table storage. Steps: 1. Start LinqPad 2. Right Click in the query window and select “Query Properties” 3. In The Additional References add reference to Microsoft.WindowsAzure.StorageClient, System.Data.Services.Client.dll and the assembly containing the implementation of the DataServiceContext class tied to the Windows Azure table storage. 4. In the additional namespace imports import the same three namespaces mentioned above. 5. Then we need to provide following details. a. Table storage account name and shared key. b. DataServiceContext implementing class in your code. c. A LINQ query. e.x.         var storageAccountName = "myStorageAccount";  // Enter valid storage account name         var storageSharedKey = "mysharedKey"; // Enter valid storage account shared key         var uri = new System.Uri("http://table.core.windows.net/");         var storageAccountInfo = new CloudStorageAccount(new StorageCredentialsAccountKey(storageAccountName, storageSharedKey), false);         var serviceContext = new TweetPollDataServiceContext(storageAccountInfo); // Specify the DataServiceContext implementation         // The query         var query = from row in serviceContext.Table                     select row;         query.Dump(); Thanks LinqPad!

I am using MonoGame as a framework and in order to support both Windows and Windows 8 metro I need to compile the shader with pixel and vertex shader 4. compile vs_4_0_level_9_1 compile ps_4_0_level_9_1 However some of the hlsl syntax has been updated with DX10 and DX11. I need to update this hlsl code: float4x4 World; float4x4 View; float4x4 Projection; float3 CameraPosition; Texture SkyBoxTexture; samplerCUBE SkyBoxSampler = sampler_state { texture = <SkyBoxTexture>; magfilter = LINEAR; minfilter = LINEAR; mipfilter = LINEAR; AddressU = Mirror; AddressV = Mirror; }; struct VertexShaderInput { float4 Position : POSITION0; }; struct VertexShaderOutput { float4 Position : POSITION0; float3 TextureCoordinate : TEXCOORD0; }; VertexShaderOutput VertexShaderFunction(VertexShaderInput input) { VertexShaderOutput output; float4 worldPosition = mul(input.Position, World); float4 viewPosition = mul(worldPosition, View); output.Position = mul(viewPosition, Projection); float4 VertexPosition = mul(input.Position, World); output.TextureCoordinate = VertexPosition - CameraPosition; return output; } float4 PixelShaderFunction(VertexShaderOutput input) : COLOR0 { return texCUBE(SkyBoxSampler, normalize(input.TextureCoordinate)); } technique Skybox { pass Pass1 { VertexShader = compile vs_2_0 VertexShaderFunction(); PixelShader = compile ps_2_0 PixelShaderFunction(); } } I quess I need to change Texture into TextureCube, change sampler, swap texCUBE() with TextureCube.Sample() and change PixelShader return semantic to SV_Target0. I'm very new in shader languages and any help is appreciated!

  • Is CUDA, cuBLAS or cuBLAS-XT the right place to start with for machine learning?

    - by Stefan R. Falk
    I am not sure if this is the right forum to post this question - but it surely is no question for stackoverflow. I work on my bachelor thesis and therefore I am implementing a so called Echo-State Network which basically is an artificial neural network that has a large reservoir of randomly initialized neurons and just a few input and output neurons .. but I think we can skip that. The thing is, there is a Python library called Theano which I am using for this implementation. It encapsulates the CUDA API and offers a quiet "comfortable" way to access the power of a NVIDIA graphics card. Since CUDA 6.0 there is a sub-library called cuBLAS (Basic Linear Algebra Subroutines) for LinAlg operations and also a cuBLAS-XT an extention which allows to run calculations on multiple graphics cards. My question at this point is if it would make sense to start using cuBLAS and/or cuBLAS-XT right now since the API is quite complex or rather wait for libraries that will build up on those library (such as Theano does on basic CUDA)? If you think this is the wrong place for this question please tell me which one is, thank you.

  • Do abstractions have to reduce code readability?

    - by Martin Blore
    A good developer I work with told me recently about some difficulty he had in implementing a feature in some code we had inherited; he said the problem was that the code was difficult to follow. From that, I looked deeper into the product and realised how difficult it was to see the code path. It used so many interfaces and abstract layers, that trying to understand where things began and ended was quite difficult. It got me thinking about the times I had looked at past projects (before I was so aware of clean code principles) and found it extremely difficult to get around in the project, mainly because my code navigation tools would always land me at an interface. It would take a lot of extra effort to find the concrete implementation or where something was wired up in some plugin type architecture. I know some developers strictly turn down dependency injection containers for this very reason. It confuses the path of the software so much that the difficulty of code navigation is exponentially increased. My question is: when a framework or pattern introduces so much overhead like this, is it worth it? Is it a symptom of a poorly implemented pattern? I guess a developer should look to the bigger picture of what that abstractions brings to the project to help them get through the frustration. Usually though, it's difficult to make them see that big picture. I know I've failed to sell the needs of IOC and DI with TDD. For those developers, use of those tools just cramps code readability far too much.

  • They Wrote The Book On It

    - by steve.diamond
    First of all, an apology to you all for my not posting this yesterday, when I should have. For those of you bloggers out there, you know the difference between "Save" and "Preview." But I temporarily forgot it. Nevertheless, while I'm not impressed with this mishap, I'm blown away by the initiative three of my colleagues have taken. Jeff Saenger, Tim Koehler, and Louis Peters, recently wrote a book, "Oracle CRM On Demand Deployment Guide." Not only that, they got this book PUBLISHED. These guys know their stuff. They have worked in the CRM industry for many years. And trust me, they command a lot of respect inside this organization. In the words of Louis Peters (who posted this verbiage yesterday on LinkedIn), "We've assembled all the best practices and lessons learned over the past six years working with CRM On Demand. The book covers a range of topics - working with SaaS-based applications, planning and executing a successful rollout, designing elegant and high-performing applications, and working effectively with Oracle. We even included several sample designs based on successful real-world deployments. Our main target audience is the CRM On Demand project team - sponsors, project managers, administrators, developers - really anyone planning, implementing or maintaining the application." Now these guys don't know it, but I'll be interviewing one of them and including audio excerpts of that conversation right here next Wednesday. In the meantime, if you want to learn more about successful CRM deployments in general, and working with Oracle CRM On Demand in particular, you should check out this book.

  • Manually writing a dx11 tessellation shader

    - by Tudor
    I am looking for resources on what are the steps of manually implementing tessellation (I'm using Unity cg). Today it seems that it is all the rage to hide most of the gpu code far away and use rather rigid simplifications such as unity's SURFace shaders. And it seems useless unless you're doing supeficial stuff. A little background: I have procedurally generated meshes (using marching cubes) which have quality normals but no UVs and no Tangents. I have successfully written a custom vertex and fragment shader to do triplanar texture and bumpmap projection as well as some custom stuff (custom lighting, procedurally warping the texture for variation etc). I am using the GPU Gems book as reference. Now I need to implement tessellation, but It seems I must calculate the tangents at runtime by swizzling normals (ctrl+f this in gems: <normal.z, normal.y, -normal.x>) before the tessellator gets them. And I also need to keep my custom vert+frag setup (with my custom parameters/textures being passed between them) - so apparently I cannot use surface shaders. Can anyone provide some guidence?

  • Entity Framework v1 &ndash; tips and Tricks Part 3

    - by Rohit Gupta
    General Tips on Entity Framework v1 & Linq to Entities: ToTraceString() If you need to know the underlying SQL that the EF generates for a Linq To Entities query, then use the ToTraceString() method of the ObjectQuery class. (or use LINQPAD) Note that you need to cast the LINQToEntities query to ObjectQuery before calling TotraceString() as follows: 1: string efSQL = ((ObjectQuery)from c in ctx.Contact 2: where c.Address.Any(a => a.CountryRegion == "US") 3: select c.ContactID).ToTraceString(); ================================================================================ MARS or MultipleActiveResultSet When you create a EDM Model (EDMX file) from the database using Visual Studio, it generates a connection string with the same name as the name of the EntityContainer in CSDL. In the ConnectionString so generated it sets the MultipleActiveResultSet attribute to true by default. So if you are running the following query then it streams multiple readers over the same connection: 1: using (BAEntities context = new BAEntities()) 2: { 3: var cons = 4: from con in context.Contacts 5: where con.FirstName == "Jose" 6: select con; 7: foreach (var c in cons) 8: { 9: if (c.AddDate < new System.DateTime(2007, 1, 1)) 10: { 11: c.Addresses.Load(); 12: } 13: } 14: } ================================================================================= Explicitly opening and closing EntityConnection When you call ToList() or foreach on a LINQToEntities query the EF automatically closes the connection after all the records from the query have been consumed. Thus if you need to run many LINQToEntities queries over the same connection then explicitly open and close the connection as follows: 1: using (BAEntities context = new BAEntities()) 2: { 3: context.Connection.Open(); 4: var cons = from con in context.Contacts where con.FirstName == "Jose" 5: select con; 6: var conList = cons.ToList(); 7: var allCustomers = from con in context.Contacts.OfType<Customer>() 8: select con; 9: var allcustList = allCustomers.ToList(); 10: context.Connection.Close(); 11: } ====================================================================== Dispose ObjectContext only if required After you retrieve entities using the ObjectContext and you are not explicitly disposing the ObjectContext then insure that your code does consume all the records from the LinqToEntities query by calling .ToList() or foreach statement, otherwise the the database connection will remain open and will be closed by the garbage collector when it gets to dispose the ObjectContext. Secondly if you are making updates to the entities retrieved using LinqToEntities then insure that you dont inadverdently dispose of the ObjectContext after the entities are retrieved and before calling .SaveChanges() since you need the SAME ObjectContext to keep track of changes made to the Entities (by using ObjectStateEntry objects). So if you do need to explicitly dispose of the ObjectContext do so only after calling SaveChanges() and only if you dont need to change track the entities retrieved any further. ======================================================================= SQL InjectionAttacks under control with EFv1 LinqToEntities and LinqToSQL queries are parameterized before they are sent to the DB hence they are not vulnerable to SQL Injection attacks. EntitySQL may be slightly vulnerable to attacks since it does not use parameterized queries. However since the EntitySQL demands that the query be valid Entity SQL syntax and valid native SQL syntax at the same time. So the only way one can do a SQLInjection Attack is by knowing the SSDL of the EDM Model and be able to write the correct EntitySQL (note one cannot append regular SQL since then the query wont be a valid EntitySQL syntax) and append it to a parameter. ====================================================================== Improving Performance You can convert the EntitySets and AssociationSets in a EDM Model into precompiled Views using the edmgen utility. for e.g. the Customer Entity can be converted into a precompiled view using edmgen and all LinqToEntities query against the contaxt.Customer EntitySet will use the precompiled View instead of the EntitySet itself (the same being true for relationships (EntityReference & EntityCollections of a Entity)). The advantage being that when using precompiled views the performance will be much better. The syntax for generating precompiled views for a existing EF project is : edmgen /mode:ViewGeneration /inssdl:BAModel.ssdl /incsdl:BAModel.csdl /inmsl:BAModel.msl /p:Chap14.csproj Note that this will only generate precompiled views for EntitySets and Associations and not for existing LinqToEntities queries in the project.(for that use CompiledQuery.Compile<>) Secondly if you have a LinqToEntities query that you need to run multiple times, then one should precompile the query using CompiledQuery.Compile method. The CompiledQuery.Compile<> method accepts a lamda expression as a parameter, which denotes the LinqToEntities query  that you need to precompile. The following is a example of a lamda that we can pass into the CompiledQuery.Compile() method 1: Expression<Func<BAEntities, string, IQueryable<Customer>>> expr = (BAEntities ctx1, string loc) => 2: from c in ctx1.Contacts.OfType<Customer>() 3: where c.Reservations.Any(r => r.Trip.Destination.DestinationName == loc) 4: select c; Then we call the Compile Query as follows: 1: var query = CompiledQuery.Compile<BAEntities, string, IQueryable<Customer>>(expr); 2:  3: using (BAEntities ctx = new BAEntities()) 4: { 5: var loc = "Malta"; 6: IQueryable<Customer> custs = query.Invoke(ctx, loc); 7: var custlist = custs.ToList(); 8: foreach (var item in custlist) 9: { 10: Console.WriteLine(item.FullName); 11: } 12: } Note that if you created a ObjectQuery or a Enitity SQL query instead of the LINQToEntities query, you dont need precompilation for e.g. 1: An Example of EntitySQL query : 2: string esql = "SELECT VALUE c from Contacts AS c where c is of(BAGA.Customer) and c.LastName = 'Gupta'"; 3: ObjectQuery<Customer> custs = CreateQuery<Customer>(esql); 1: An Example of ObjectQuery built using ObjectBuilder methods: 2: from c in Contacts.OfType<Customer>().Where("it.LastName == 'Gupta'") 3: select c This is since the Query plan is cached and thus the performance improves a bit, however since the ObjectQuery or EntitySQL query still needs to materialize the results into Entities hence it will take the same amount of performance hit as with LinqToEntities. However note that not ALL EntitySQL based or QueryBuilder based ObjectQuery plans are cached. So if you are in doubt always create a LinqToEntities compiled query and use that instead ============================================================ GetObjectStateEntry Versus GetObjectByKey We can get to the Entity being referenced by the ObjectStateEntry via its Entity property and there are helper methods in the ObjectStateManager (osm.TryGetObjectStateEntry) to get the ObjectStateEntry for a entity (for which we know the EntityKey). Similarly The ObjectContext has helper methods to get an Entity i.e. TryGetObjectByKey(). TryGetObjectByKey() uses GetObjectStateEntry method under the covers to find the object, however One important difference between these 2 methods is that TryGetObjectByKey queries the database if it is unable to find the object in the context, whereas TryGetObjectStateEntry only looks in the context for existing entries. It will not make a trip to the database ============================================================= POCO objects with EFv1: To create POCO objects that can be used with EFv1. We need to implement 3 key interfaces: IEntityWithKey IEntityWithRelationships IEntityWithChangeTracker Implementing IEntityWithKey is not mandatory, but if you dont then we need to explicitly provide values for the EntityKey for various functions (for e.g. the functions needed to implement IEntityWithChangeTracker and IEntityWithRelationships). Implementation of IEntityWithKey involves exposing a property named EntityKey which returns a EntityKey object. Implementation of IEntityWithChangeTracker involves implementing a method named SetChangeTracker since there can be multiple changetrackers (Object Contexts) existing in memory at the same time. 1: public void SetChangeTracker(IEntityChangeTracker changeTracker) 2: { 3: _changeTracker = changeTracker; 4: } Additionally each property in the POCO object needs to notify the changetracker (objContext) that it is updating itself by calling the EntityMemberChanged and EntityMemberChanging methods on the changeTracker. for e.g.: 1: public EntityKey EntityKey 2: { 3: get { return _entityKey; } 4: set 5: { 6: if (_changeTracker != null) 7: { 8: _changeTracker.EntityMemberChanging("EntityKey"); 9: _entityKey = value; 10: _changeTracker.EntityMemberChanged("EntityKey"); 11: } 12: else 13: _entityKey = value; 14: } 15: } 16: ===================== Custom Property ==================================== 17:  18: [EdmScalarPropertyAttribute(IsNullable = false)] 19: public System.DateTime OrderDate 20: { 21: get { return _orderDate; } 22: set 23: { 24: if (_changeTracker != null) 25: { 26: _changeTracker.EntityMemberChanging("OrderDate"); 27: _orderDate = value; 28: _changeTracker.EntityMemberChanged("OrderDate"); 29: } 30: else 31: _orderDate = value; 32: } 33: } Finally you also need to create the EntityState property as follows: 1: public EntityState EntityState 2: { 3: get { return _changeTracker.EntityState; } 4: } The IEntityWithRelationships involves creating a property that returns RelationshipManager object: 1: public RelationshipManager RelationshipManager 2: { 3: get 4: { 5: if (_relManager == null) 6: _relManager = RelationshipManager.Create(this); 7: return _relManager; 8: } 9: } ============================================================ Tip : ProviderManifestToken – change EDMX File to use SQL 2008 instead of SQL 2005 To use with SQL Server 2008, edit the EDMX file (the raw XML) changing the ProviderManifestToken in the SSDL attributes from "2005" to "2008" ============================================================= With EFv1 we cannot use Structs to replace a anonymous Type while doing projections in a LINQ to Entities query. While the same is supported with LINQToSQL, it is not with LinqToEntities. For e.g. the following is not supported with LinqToEntities since only parameterless constructors and initializers are supported in LINQ to Entities. (the same works with LINQToSQL) 1: public struct CompanyInfo 2: { 3: public int ID { get; set; } 4: public string Name { get; set; } 5: } 6: var companies = (from c in dc.Companies 7: where c.CompanyIcon == null 8: select new CompanyInfo { Name = c.CompanyName, ID = c.CompanyId }).ToList(); ;

  • SQLAuthority News – Download Whitepaper – A Case Study on “Hekaton” against RPM – SQL Server 2014 CTP1

    - by Pinal Dave
    In this new world of social media, apps and mobile devices, we are all now getting impatient. Automatic updates have spoiled few of our habits. When a new feature is released everybody wants to immediately adopt the feature and start using it. Though this is true in the world of apps and smart phones, but it is still not possible in the developer’s world. When new features are around, before we start using it, we need to spend quite a lots of time to understand it and test it. Once we are sold on the feature we refer the feature to our manager and eventually the entire organization makes decisions on upgrading to use the new feature. Similarly, when the new feature of In-Memory OLTP was announced, pretty much every SQL Server DBA wanted to implement that on their server. Through the implementation of the feature is not hard, it is not that easy as well. One has to do proper research about their own environment and workload before implementing this feature. Microsoft has recently released a Case Study on In-Memory OLTP feature. Here is the abstract from the white paper itself. I/O latch can cause session delays that impact application performance. This white paper describes the procedures and common I/O latch issues when migrating to Hekaton in SQL Server 2014. It also includes challenges that occurred during the migration and the performance analysis at different stages.  If you are going to implement In-Memory OLTP database, this is a good case study to refer.
