• Automated SSRS deployment with the RS utility

  - by Stacy Vicknair

  If you’re familiar with SSRS and development you are probably aware of the SSRS web services. The RS utility is a tool that comes with SSRS that allows for scripts to be executed against against the SSRS web service without needing to create an application to consume the service. One of the better benefits of using this format rather than writing an application is that the script can be modified by others who might be involved in the creation and addition of scripts or management of the SSRS environment.   Reporting Services Scripter Jasper Smith from http://www.sqldbatips.com created Reporting Services Scripter to assist with the created of a batch process to deploy an entire SSRS environment. The helper scripts below were created through the modification of his generated scripts. Why not just use this tool? You certainly can. For me, the volume of scripts generated seems less maintainable than just using some common methods extracted from these scripts and creating a deployment in a single script file. I would, however, recommend this as a product if you do not think that your environment will change drastically or if you do not need to deploy with a higher level of control over the deployment. If you just need to replicate, this tool works great. Executing with RS.exe Executing a script against rs.exe is fairly simple. The Script Half the battle is having a starting point. For the scripting I needed to do the below is the starter script. A few notes: This script assumes integrated security. This script assumes your reports have one data source each. Both of the above are just what made sense for my scenario and are definitely modifiable to accommodate your needs. If you are unsure how to change the scripts to your needs, I recommend Reporting Services Scripter to help you understand how the differences. The script has three main methods: CreateFolder, CreateDataSource and CreateReport. Scripting the server deployment is just a process of recreating all of the elements that you need through calls to these methods. If there are additional elements that you need to deploy that aren’t covered by these methods, again I suggest using Reporting Services Scripter to get the code you would need, convert it to a repeatable method and add it to this script! Public Sub Main() CreateFolder("/", "Data Sources") CreateFolder("/", "My Reports") CreateDataSource("/Data Sources", "myDataSource", _ "Data Source=server\instance;Initial Catalog=myDatabase") CreateReport("/My Reports", _ "MyReport", _ "C:\myreport.rdl", _ True, _ "/Data Sources", _ "myDataSource") End Sub   Public Sub CreateFolder(parent As String, name As String) Dim fullpath As String = GetFullPath(parent, name) Try RS.CreateFolder(name, parent, GetCommonProperties()) Console.WriteLine("Folder created: {0}", name) Catch e As SoapException If e.Detail.Item("ErrorCode").InnerText = "rsItemAlreadyExists" Then Console.WriteLine("Folder {0} already exists and cannot be overwritten", fullpath) Else Console.WriteLine("Error : " + e.Detail.Item("ErrorCode").InnerText + " (" + e.Detail.Item("Message").InnerText + ")") End If End Try End Sub   Public Sub CreateDataSource(parent As String, name As String, connectionString As String) Try RS.CreateDataSource(name, parent,False, GetDataSourceDefinition(connectionString), GetCommonProperties()) Console.WriteLine("DataSource {0} created successfully", name) Catch e As SoapException Console.WriteLine("Error : " + e.Detail.Item("ErrorCode").InnerText + " (" + e.Detail.Item("Message").InnerText + ")") End Try End Sub   Public Sub CreateReport(parent As String, name As String, location As String, overwrite As Boolean, dataSourcePath As String, dataSourceName As String) Dim reportContents As Byte() = Nothing Dim warnings As Warning() = Nothing Dim fullpath As String = GetFullPath(parent, name)   'Read RDL definition from disk Try Dim stream As FileStream = File.OpenRead(location) reportContents = New [Byte](stream.Length-1) {} stream.Read(reportContents, 0, CInt(stream.Length)) stream.Close()   warnings = RS.CreateReport(name, parent, overwrite, reportContents, GetCommonProperties())   If Not (warnings Is Nothing) Then Dim warning As Warning For Each warning In warnings Console.WriteLine(Warning.Message) Next warning Else Console.WriteLine("Report: {0} published successfully with no warnings", name) End If   'Set report DataSource references Dim dataSources(0) As DataSource   Dim dsr0 As New DataSourceReference dsr0.Reference = dataSourcePath Dim ds0 As New DataSource ds0.Item = CType(dsr0, DataSourceDefinitionOrReference) ds0.Name=dataSourceName dataSources(0) = ds0     RS.SetItemDataSources(fullpath, dataSources)   Console.Writeline("Report DataSources set successfully")       Catch e As IOException Console.WriteLine(e.Message) Catch e As SoapException Console.WriteLine("Error : " + e.Detail.Item("ErrorCode").InnerText + " (" + e.Detail.Item("Message").InnerText + ")") End Try End Sub     Public Function GetCommonProperties() As [Property]() 'Common CatalogItem properties Dim descprop As New [Property] descprop.Name = "Description" descprop.Value = "" Dim hiddenprop As New [Property] hiddenprop.Name = "Hidden" hiddenprop.Value = "False"   Dim props(1) As [Property] props(0) = descprop props(1) = hiddenprop Return props End Function   Public Function GetDataSourceDefinition(connectionString as String) Dim definition As New DataSourceDefinition definition.CredentialRetrieval = CredentialRetrievalEnum.Integrated definition.ConnectString = connectionString definition.Enabled = True definition.EnabledSpecified = True definition.Extension = "SQL" definition.ImpersonateUser = False definition.ImpersonateUserSpecified = True definition.Prompt = "Enter a user name and password to access the data source:" definition.WindowsCredentials = False definition.OriginalConnectStringExpressionBased = False definition.UseOriginalConnectString = False Return definition End Function   Private Function GetFullPath(parent As String, name As String) As String If parent = "/" Then Return parent + name Else Return parent + "/" + name End If End Function

• [EF + Oracle] Entities

  - by JTorrecilla

  Prologue Following with the Serie I started yesterday about Entity Framework with Oracle, Today I am going to start talking about Entities. What is an Entity? A Entity is an object of the EF model corresponding to a record in a DB table. For example, let’s see, in Image 1 we can see one Entity from our model, and in the second one we can see the mapping done with the DB. (Image 1) (Image 2) More in depth a Entity is a Class inherited from the abstract class “EntityObject”, contained by the “System.Data.Objects.DataClasses” namespace. At the same time, this class inherits from the following Class and interfaces: StructuralObject: It is an Abstract class that inherits from INotifyPropertyChanging and INotifyPropertyChanged interfaces, and it exposes the events that manage the Changes of the class, and the functions related to check the data types of the Properties from our Entity.  IEntityWithKey: Interface which exposes the Key of the entity. IEntityWithChangeTracker: Interface which lets indicate the state of the entity (Detached, Modified, Added…) IEntityWithRelationships: Interface which indicates the relations about the entity. Which is the Content of a Entity? A Entity is composed by: Properties, Navigation Properties and Methods. What is a Property? A Entity Property is an object that represents a column from the mapped table from DB. It has a data type equivalent in .Net Framework to the DB Type. When we create the EF model, VS, internally, create the code for each Entity selected in the Tables step, such all methods that we will see in next steps. For each property, VS creates a structure similar to: · Private variable with the mapped Data type. · Function with a name like On{Property_Name}Changing({dataType} value): It manages the event which happens when we try to change the value. · Function with a name like On{Property_Name}Change: It manages the event raised when the property has changed successfully. · Property with Get and Set methods: The Set Method manages the private variable and do the following steps: Raise Changing event. Report the Entity is Changing. Set the prívate variable. For it, Use the SetValidValue function of the StructuralObject. There is a function for each datatype, and the functions takes 2 params: the value, and if the prop allow nulls. Invoke that the entity has been successfully changed. Invoke the Changed event of the Prop. ReportPropertyChanging and ReportPropertyChanged events, let, respectively, indicate that there is pending changes in the Entity, and the changes have success correctly. While the ReportPropertyChanged is raised, the Track State of the Entity will be changed. What is a Navigation Property? Navigation Properties are a kind of property of the type: EntityCollection<TEntity>, where TEntity is an Entity type from the model related with the current one, it is said, is a set of record from a related table in the DB. The EntityCollection class inherits from: · RelatedEnd: There is an abstract class that give the functions needed to obtein the related objects. · ICollection<TEntity> · IEnumerable<TEntity> · IEnumerable · IListSource For the previous interfaces, I wish recommend the following post from Jose Miguel Torres. Navigation properties allow us, to get and query easily objects related with the Entity. Methods? There is only one method in the Entity object. “Create{Entity}”, that allow us to create an object of the Entity by sending the parameters needed to create it. Finally After this chapter, we know what is an Entity, how is related to the DB and the relation to other Entities. In following chapters, we will se CRUD operations(Create, Read, Update, Delete).

• SQL Azure: Notes on Building a Shard Technology

  - by Herve Roggero

  In Chapter 10 of the book on SQL Azure (http://www.apress.com/book/view/9781430229612) I am co-authoring, I am digging deeper in what it takes to write a Shard. It's actually a pretty cool exercise, and I wanted to share some thoughts on how I am designing the technology. A Shard is a technology that spreads the load of database requests over multiple databases, as transparently as possible. The type of shard I am building is called a Vertical Partition Shard  (VPS). A VPS is a mechanism by which the data is stored in one or more databases behind the scenes, but your code has no idea at design time which data is in which database. It's like having a mini cloud for records instead of services. Imagine you have three SQL Azure databases that have the same schema (DB1, DB2 and DB3), you would like to issue a SELECT * FROM Users on all three databases, concatenate the results into a single resultset, and order by last name. Imagine you want to ensure your code doesn't need to change if you add a new database to the shard (DB4). Now imagine that you want to make sure all three databases are queried at the same time, in a multi-threaded manner so your code doesn't have to wait for three database calls sequentially. Then, imagine you would like to obtain a breadcrumb (in the form of a new, virtual column) that gives you a hint as to which database a record came from, so that you could update it if needed. Now imagine all that is done through the standard SqlClient library... and you have the Shard I am currently building. Here are some lessons learned and techniques I am using with this shard: Parellel Processing: Querying databases in parallel is not too hard using the Task Parallel Library; all you need is to lock your resources when needed Deleting/Updating Data: That's not too bad either as long as you have a breadcrumb. However it becomes more difficult if you need to update a single record and you don't know in which database it is. Inserting Data: I am using a round-robin approach in which each new insert request is directed to the next database in the shard. Not sure how to deal with Bulk Loads just yet... Shard Databases:  I use a static collection of SqlConnection objects which needs to be loaded once; from there on all the Shard commands use this collection Extension Methods: In order to make it look like the Shard commands are part of the SqlClient class I use extension methods. For example I added ExecuteShardQuery and ExecuteShardNonQuery methods to SqlClient. Exceptions: Capturing exceptions in a multi-threaded code is interesting... but I kept it simple for now. I am using the ConcurrentQueue to store my exceptions. Database GUID: Every database in the shard is given a GUID, which is calculated based on the connection string's values. DataTable. The Shard methods return a DataTable object which can be bound to objects.  I will be sharing the code soon as an open-source project in CodePlex. Please stay tuned on twitter to know when it will be available (@hroggero). Or check www.bluesyntax.net for updates on the shard. Thanks!

• Indexing data from multiple tables with Oracle Text

  - by Roger Ford

  It's well known that Oracle Text indexes perform best when all the data to be indexed is combined into a single index. The query select * from mytable where contains (title, 'dog') 0 or contains (body, 'cat') 0 will tend to perform much worse than select * from mytable where contains (text, 'dog WITHIN title OR cat WITHIN body') 0 For this reason, Oracle Text provides the MULTI_COLUMN_DATASTORE which will combine data from multiple columns into a single index. Effectively, it constructs a "virtual document" at indexing time, which might look something like: <title>the big dog</title> <body>the ginger cat smiles</body> This virtual document can be indexed using either AUTO_SECTION_GROUP, or by explicitly defining sections for title and body, allowing the query as expressed above. Note that we've used a column called "text" - this might have been a dummy column added to the table simply to allow us to create an index on it - or we could created the index on either of the "real" columns - title or body. It should be noted that MULTI_COLUMN_DATASTORE doesn't automatically handle updates to columns used by it - if you create the index on the column text, but specify that columns title and body are to be indexed, you will need to arrange triggers such that the text column is updated whenever title or body are altered. That works fine for single tables. But what if we actually want to combine data from multiple tables? In that case there are two approaches which work well: Create a real table which contains a summary of the information, and create the index on that using the MULTI_COLUMN_DATASTORE. This is simple, and effective, but it does use a lot of disk space as the information to be indexed has to be duplicated. Create our own "virtual" documents using the USER_DATASTORE. The user datastore allows us to specify a PL/SQL procedure which will be used to fetch the data to be indexed, returned in a CLOB, or occasionally in a BLOB or VARCHAR2. This PL/SQL procedure is called once for each row in the table to be indexed, and is passed the ROWID value of the current row being indexed. The actual contents of the procedure is entirely up to the owner, but it is normal to fetch data from one or more columns from database tables. In both cases, we still need to take care of updates - making sure that we have all the triggers necessary to update the indexed column (and, in case 1, the summary table) whenever any of the data to be indexed gets changed. I've written full examples of both these techniques, as SQL scripts to be run in the SQL*Plus tool. You will need to run them as a user who has CTXAPP role and CREATE DIRECTORY privilege. Part of the data to be indexed is a Microsoft Word file called "1.doc". You should create this file in Word, preferably containing the single line of text: "test document". This file can be saved anywhere, but the SQL scripts need to be changed so that the "create or replace directory" command refers to the right location. In the example, I've used C:\doc. multi_table_indexing_1.sql : creates a summary table containing all the data, and uses multi_column_datastore Download link / View in browser multi_table_indexing_2.sql : creates "virtual" documents using a procedure as a user_datastore Download link / View in browser

• Browser Specific Extensions of HttpClient

  - by imran_ku07

          Introduction:                     REpresentational State Transfer (REST) causing/leaving a great impact on service/API development because it offers a way to access a service without requiring any specific library by embracing HTTP and its features. ASP.NET Web API makes it very easy to quickly build RESTful HTTP services. These HTTP services can be consumed by a variety of clients including browsers, devices, machines, etc. With .NET Framework 4.5, we can use HttpClient class to consume/send/receive RESTful HTTP services(for .NET Framework 4.0, HttpClient class is shipped as part of ASP.NET Web API). The HttpClient class provides a bunch of helper methods(for example, DeleteAsync, PostAsync, GetStringAsync, etc.) to consume a HTTP service very easily. ASP.NET Web API added some more extension methods(for example, PutAsJsonAsync, PutAsXmlAsync, etc) into HttpClient class to further simplify the usage. In addition, HttpClient is also an ideal choice for writing integration test for a RESTful HTTP service. Since a browser is a main client of any RESTful API, it is also important to test the HTTP service on a variety of browsers. RESTful service embraces HTTP headers and different browsers send different HTTP headers. So, I have created a package that will add overloads(with an additional Browser parameter) for almost all the helper methods of HttpClient class. In this article, I will show you how to use this package.           Description:                     Create/open your test project and install ImranB.SystemNetHttp.HttpClientExtensions NuGet package. Then, add this using statement on your class, using ImranB.SystemNetHttp;                     Then, you can start using any HttpClient helper method which include the additional Browser parameter. For example,  var client = new HttpClient(myserver); var task = client.GetAsync("http://domain/myapi", Browser.Chrome); task.Wait(); var response = task.Result; .                     Here is the definition  of Browser, public enum Browser { Firefox = 0, Chrome = 1, IE10 = 2, IE9 = 3, IE8 = 4, IE7 = 5, IE6 = 6, Safari = 7, Opera = 8, Maxthon = 9, }                     These extension methods will make it very easy to write browser specific integration test. It will also help HTTP service consumer to mimic the request sending behavior of a browser. This package source is available on github. So, you can grab the source and add some additional behavior on the top of these extensions.         Summary:                     Testing a REST API is an important aspect of service development and today, testing with a browser is crucial. In this article, I showed how to write integration test that will mimic the browser request sending behavior. I also showed an example. Hopefully you will enjoy this article too.

• Flow-Design Cheat Sheet &ndash; Part II, Translation

  - by Ralf Westphal

  In my previous post I summarized the notation for Flow-Design (FD) diagrams. Now is the time to show you how to translate those diagrams into code. Hopefully you feel how different this is from UML. UML leaves you alone with your sequence diagram or component diagram or activity diagram. They leave it to you how to translate your elaborate design into code. Or maybe UML thinks it´s so easy no further explanations are needed? I don´t know. I just know that, as soon as people stop designing with UML and start coding, things end up to be very different from the design. And that´s bad. That degrades graphical designs to just time waste on paper (or some designer). I even believe that´s the reason why most programmers view textual source code as the only and single source of truth. Design and code usually do not match. FD is trying to change that. It wants to make true design a first class method in every developers toolchest. For that the first prerequisite is to be able to easily translate any design into code. Mechanically, without thinking. Even a compiler could do it :-) (More of that in some other article.) Translating to Methods The first translation I want to show you is for small designs. When you start using FD you should translate your diagrams like this. Functional units become methods. That´s it. An input-pin becomes a method parameter, an output-pin becomes a return value: The above is a part. But a board can be translated likewise and calls the nested FUs in order: In any case be sure to keep the board method clear of any and all business logic. It should not contain any control structures like if, switch, or a loop. Boards do just one thing: calling nested functional units in proper sequence. What about multiple input-pins? Try to avoid them. Replace them with a join returning a tuple: What about multiple output-pins? Try to avoid them. Or return a tuple. Or use out-parameters: But as I said, this simple translation is for simple designs only. Splits and joins are easily done with method translation: All pretty straightforward, isn´t it. But what about wires, named pins, entry points, explicit dependencies? I suggest you don´t use this kind of translation when your designs need these features. Translating to methods is for small scale designs like you might do once you´re working on the implementation of a part of a larger design. Or maybe for a code kata you´re doing in your local coding dojo. Instead of doing TDD try doing FD and translate your design into methods. You´ll see that way it´s much easier to work collaboratively on designs, remember them more easily, keep them clean, and lessen the need for refactoring. Translating to Events [coming soon]

Which means if you have zero time between now and next Wednesday then you are still good to go. But if you can do some pre-work you will likely get even more out of the three days. Step 1: Check out the topics and resources available on-demand The course is based around a subset of the channel 9 training to allow you to easily dig deeper or look again at specific areas. Take a lap around the SharePoint 2010 Training Course on Channel 9 Download the SharePoint Developer Training Kit Step 2: Use a pre-configured Virtual Machine which you can download (best start today – it is large!) Consider using the VM we created If you don't have access to SharePoint 2010. You will need a 64bit host OS and bare minimum of 4GB of RAM. 8GB recommended. Virtual PC can not be used with this VM – Virtual PC only supports 32bit guests. The 2010-7a Information Worker VM gives you everything you need to develop for SharePoint 2010. Watch the Video on how to use this VM Download the VM Remember you only need to download the “parts” for the 2010-7a VM. There are 3 subtly different ways of using this VM: Easiest is to follow the advice of the video and get yourself a host OS of Windows Server 2008 R2 with Hyper-V and simply use the VM Alternatively you can take the VHD and create a “Boot to VHD” if you have Windows 7 Ultimate or Enterprise Edition. This works really well – especially if you are already familiar with “Boot to VHD” (This post I did will help you get started) Or you can take the VHD and use an alternative VM tool such as VirtualBox if you have a different host OS. NB: This tends to involve some work to get everything running fine. Check out parts 1 to 3 from Rolly and if you go with Virtual Box use an IDE controller not SATA. SATA will blue screen. Note in the screenshot below I also converted the vhd to a vmdk. I used the FREE Starwind Converter to do this whilst I was fighting blue screens – not sure its necessary as VirtualBox does now work with VHDs. or Step 3 – Install SharePoint 2010 on a 64bit Windows 7 or Vista Host I haven’t tried this but it is now supported. Check out MSDN. Final notes: I am in the process of securing a number of hosted VMs for ISVs directly managed by my team. Your Architect Evangelist will have details once I have them! Else we can sort out on the Wed. Regrettably I am unable to give folks 1:1 support on any issues around Boot to VHD, 3rd party VM products etc. Related Links: Check you are fully plugged into the work of my team – have you done these simple steps including joining our new LinkedIn group?

• How to resize / enlarge / grow a non-LVM ext4 partition

  - by Mischa

  I have already searched the forums, but couldnt find a good suitable answer: I have an Ubuntu Server 10.04 as KVM Host and a guest system, that also runs 10.04. The host system uses LVM and there are three logical volumes, which are provided to the guest as virtual block devices - one for /, one for /home and one for swap. The guest had been partitioned without LVM. I have already enlarged the logical volume in the host system - the guest successfully sees the bigger virtual disk. However, this virtual disk contains one "good old" partition, which still has the old small size. The output of fdisk -l is me@produktion:/$ LC_ALL=en_US sudo fdisk -l Disk /dev/vda: 32.2 GB, 32212254720 bytes 255 heads, 63 sectors/track, 3916 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000c8ce7 Device Boot Start End Blocks Id System /dev/vda1 * 1 3917 31455232 83 Linux Disk /dev/vdb: 2147 MB, 2147483648 bytes 244 heads, 47 sectors/track, 365 cylinders Units = cylinders of 11468 * 512 = 5871616 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000f2bf7 Device Boot Start End Blocks Id System /dev/vdb1 1 366 2095104 82 Linux swap / Solaris Partition 1 has different physical/logical beginnings (non-Linux?): phys=(0, 32, 33) logical=(0, 43, 28) Partition 1 has different physical/logical endings: phys=(260, 243, 47) logical=(365, 136, 44) Disk /dev/vdc: 225.5 GB, 225485783040 bytes 255 heads, 63 sectors/track, 27413 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00027f25 Device Boot Start End Blocks Id System /dev/vdc1 1 9138 73398272 83 Linux The output of parted print all is Model: Virtio Block Device (virtblk) Disk /dev/vda: 32.2GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 32.2GB 32.2GB primary ext4 boot Model: Virtio Block Device (virtblk) Disk /dev/vdb: 2147MB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 2146MB 2145MB primary linux-swap(v1) Model: Virtio Block Device (virtblk) Disk /dev/vdc: 225GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 75.2GB 75.2GB primary ext4 What I want to achieve is to simply grow or resize the partition /dev/vdc1 so that it uses the whole space provided by the virtual block device /dev/vdc.

• Rolling Along: PASS Board Year 2, Q2

  - by Denise McInerney

  Eighteen months into my time as a PASS Director I’m especially proud of what the Virtual Chapters have accomplished and want to share that progress with you. I'm also pleased that the organization has invested more resources to support the VCs. In this quarter I got to attend two conferences and meet more members of the SQL community. Virtual Chapters In the first six months of 2013 VCs have hosted more than 50 webinars, offering free technical education to over 6200 attendees. This is a great benefit to PASS members; thanks to the VC leaders, volunteers and speakers who contribute their time to produce these events. The Performance VC held their “Summer Performance Palooza”, an event featuring eight back-to-back sessions. Links to the session recordings can be found on the VCs web site. The new webinar platform, GoToWebinar, has been rolled out to all the VCs. This is a more stable, scalable platform and represents an important investment into the future of the VCs. A few new VCs are in the planning stages, including one focused on Security and one for Russian speakers. Visit the Virtual Chapter home page to sign up for the chapters that interest you. Each Virtual Chapter is offering a discount code for PASS Summit 2013. Be sure to ask your VC leader for the code to save $200 on Summit registration. 24 Hours of PASS The next 24HOP will be on July 31. This Summit Preview edition will feature 24 consecutive webcasts presented by experts who will be speaking at Summit in October. Registration for this free event is open now. And we will be using the GoToWebinar platform for 24HOP also. Business Analytics Conference April marked the first PASS Business Analytics Conference in Chicago. This introduced PASS to another segment of data professionals: the analysts and data scientists who work with the world’s growing collection of data. Overall the inaugural event was a success and gave us a glimpse into this increasingly important space. After Chicago the Board had several serious discussions about the lessons learned from this seven and what we should do next. We agreed to apply those lessons and continue to invest in this event; there will be a PASS Business Analytics Conference in 2014. I’m very pleased the next event will be in San Jose, CA, the heart of Silicon Valley, a place where a great deal of investment and innovation in data analytics is taking place. Global SQL Community Over the last couple of years PASS has been taking steps to become more relevant to SQL communities in different parts of the world. In May I had the opportunity to attend SQL Bits XI in Nottingham, England. It was enlightening to meet and talk with SQL professionals from around the U.K. as well as many other European countries. The many SQL Bits volunteers put on a great event and were gracious hosts. Budgets The Board passed the FY14 budget at the end of June. The  budget process can be challenging and requires the Board to make some difficult choices about where to allocate resources. Overall I’m satisfied with the decisions we made and think we are investing in the right activities and programs. Next Up The Board is meeting July 18-19 in Kansas City. We will be holding the Executive Committee election for the Exec Co that will take office in 2014. We will also be discussing plans for the next BA conference as well as the next steps for our Global Growth initiative. Applications for the upcoming Board of Directors election open on July 24. If you are considering running for the Board you can visit the PASS elections site to learn more about the election process. And I encourage anyone considering running to reach out to current and past Board members to learn about what the role entails. Plans for the next PASS Summit are in full swing. We are working on some fun new ideas to introduce attendees to the many ways to become involved in the SQL community.

• Doubts about several best practices for rest api + service layer

  - by TheBeefMightBeTough

  I'm going to be starting a project soon that exposes a restful api for business intelligence. It may not be limited to a restful api, so I plan to delegate requests to a service layer that then coordinates multiple domain objects (each of which have business logic local to the object). The api will likely have many calls as it is a long-term project. While thinking about the design, I recalled a few best practices. 1) Use command objects at the controller layer (I'm using Spring MVC). 2) Use DTOs at the service layer. 3) Validate in both the controller and service layer, though for different reasons. I have my doubts about these recommendations. 1) Using command objects adds a lot of extra single-purpose classes (potentially one per request). What exactly is the benefit? Annotation based validation can be done using this approach, sure. What if I have two requests that take the same parameters, but have different validation requirements? I would have to have two different classes with exactly the same members but different annotations? Bleh. 2) I have heard that using DTOs is preferable to parameters because it makes for more maintainable code down the road (say, e.g., requirements change and the service parameters need to be altered). I don't quite understand this. Shouldn't an api be more-or-less set in stone? I would understand that in the early phases of a project (or, especially, an entire company) the domain itself will not be well understood, and thus core domain objects may change along with the apis that manipulate these objects. At this point however the number of api methods should be small and their dependents few, so changes to the methods could easily be tolerated from a maintainability standpoint. In a large api with many methods and a substantial domain model, I would think having a DTO for potentially each domain object would become unwieldy. Am I misunderstanding something here? 3) I see validation in the controller and service layer as redundant in most cases. Why would I validate that parameters are not null and are in general well formed in the controller if the service is going to do exactly the same (and more). Couldn't I just do all the validation in the service and throw a runtime exception with a list of bad parameters then catch that in the controller to make the error messages more presentable? Better yet, couldn't I just make the error messages user-friendly in the service and let the exception trickle up to a global handler (ControllerAdvice in spring, for example)? Is there something wrong with either of these approaches? (I do see a use case for controller validation if the input does not map one-to-one with the service input, but since the controllers are for a rest api and not forms, the api parameters will probably map directly to service parameters.) I do also have a question about unchecked vs checked exceptions. Namely, I'm not really sure why I'd ever want to use a checked exception. Every time I have seen them used they just get wrapped into general exceptions (DomainException, SystemException, ApplicationException, w/e) to reduce the signature length of methods, or devs catch Exception rather than dealing with the App1Exception, App2Exception, Sys1Exception, Sys2Exception. I don't see how either of these practices is very useful. Why not just use unchecked exceptions always and catch the ones you actually do care about? You could just document what unchecked exceptions the method throws.

• Profiling Startup Of VS2012 &ndash; dotTrace Profiler

  - by Alois Kraus

  Jetbrains which is famous for the Resharper tool has also a profiler in its portfolio. I downloaded dotTrace 5.2 Professional (569€+VAT) to check how far I can profile the startup of VS2012. The most interesting startup option is “.NET Process”. With that you can profile the next started .NET process which is very useful if you want to profile an application which is not started by you.     I did select Tracing as and Wall time to get similar options across all profilers. For some reason the attach option did not work with .NET 4.5 on my home machine. But I am sure that it did work with .NET 4.0 some time ago. Since we are profiling devenv.exe we can also select “Standalone Application” and start it from the profiler. The startup time of VS does increase about a factor 3 but that is ok. You get mainly three windows to work with. The first one shows the threads where you can drill down thread wise where most time is spent. I The next window is the call tree which does merge all threads together in a similar view. The last and most useful view in my opinion is the Plain List window which is nearly the same as the Method Grid in Ants Profiler. But this time we do get when I enable the Show system functions checkbox not a 150 but 19407 methods to choose from! I really tried with Ants Profiler to find something about out how VS does work but look how much we were missing! When I double click on a method I do get in the lower pane the called methods and their respective timings. This is something really useful and I can nicely drill down to the most important stuff. The measured time seems to be Wall Clock time which is a good thing to see where my time is really spent. You can also use Sampling as profiling method but this does give you much less information. Except for getting a first idea where to look first this profiling mode is not very useful to understand how you system does interact.   The options have a good list of presets to hide by default many method and gray them out to concentrate on your code. It does not filter anything out if you enable Show system functions. By default methods from these assemblies are hidden or if the checkbox is checked grayed out. All in all JetBrains has made a nice profiler which does show great detail and it has nice drill down capabilities. The only thing is that I do not trust its measured timings. I did fall several times into the trap with this one to optimize at places which were already fast but the profiler did show high times in these methods. After measuring with Tracing I was certain that the measured times were greatly exaggerated. Especially when IO is involved it seems to have a hard time to subtract its own overhead. What I did miss most was the possibility to profile not only the next started process but to be able to select a process by name and perhaps a count to profile the next n processes of this name.

• Identity in .NET 4.5&ndash;Part 3: (Breaking) changes

  - by Your DisplayName here!

  I recently started porting a private build of Thinktecture.IdentityModel to .NET 4.5 and noticed a number of changes. The good news is that I can delete large parts of my library because many features are now in the box. Along the way I found some other nice additions. ClaimsIdentity now has methods to query the claims collection, e.g. HasClaim(), FindFirst(), FindAll(). ClaimsPrincipal has those methods as well. But they work across all contained identities. Nice! ClaimsPrincipal.Current retrieves the ClaimsPrincipal from Thread.CurrentPrincipal. Combined with the above changes, no casting necessary anymore. SecurityTokenHandler now has read and write methods that work directly with strings. This makes it much easier to deal with non-XML tokens like SWT or JWT. A new session security token handler that uses the ASP.NET machine key to protect the cookie. This makes it easier to get started in web farm scenarios. No need for a custom service host factory or the federation behavior anymore. WCF can be switched into “WIF mode” with the useIdentityConfiguration switch (odd name though). Tooling has become better and the new test STS makes it very easy to get started. On the other hand – and that was kind of expected – to bring claims into the core framework, there are also some breaking changes for WIF code. If you want to migrate (and I would recommend that), most changes to your code are mechanical. The following is a brain dump of the changes I encountered. Assembly Microsoft.IdentityModel is gone. The new functionality is now in mscorlib, System.IdentityModel(.Services) and System.ServiceModel. All the namespaces have changed as well. No IClaimsPrincipal and IClaimsIdentity anymore. Configuration section has been split into <system.identityModel /> and <system.identityModel.services />. WCF configuration story has changed as well. Claim.ClaimType is now Claim.Type. ClaimCollection is now IEnumerable<Claim>. IsSessionMode is now IsReferenceMode. Bootstrap token handling is different now. ClaimsPrincipalHttpModule is gone. This is not really needed anymore, apart from maybe claims transformation (see here). Various factory methods on ClaimsPrincipal are gone (e.g. ClaimsPrincipal.CreateFromIdentity()). SecurityTokenHandler.ValidateToken now returns a ReadOnlyCollection<ClaimsIdentity>. Some lower level helper classes are gone or internal now (e.g. KeyGenerator). The WCF WS-Trust bindings are gone. I think this is a pity. They were *really* useful when doing work with WSTrustChannelFactory. Since WIF is part of the Windows operating system and also supported in future versions of .NET, there is no urgent need to migrate to the 4.5 claims model. But obviously, going forward, at some point you want to make the move.

• saslauthd + PostFix producing password verification and authentication errors

  - by Aram Papazian

  So I'm trying to setup PostFix while using SASL (Cyrus variety preferred, I was using dovecot earlier but I'm switching from dovecot to courier so I want to use cyrus instead of dovecot) but I seem to be having issues. Here are the errors I'm receiving: ==> mail.log <== Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: SASL authentication failure: Password verification failed Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: ipname[xx.xx.xx.xx]: SASL PLAIN authentication failed: authentication failure ==> mail.info <== Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: SASL authentication failure: Password verification failed Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: ipname[xx.xx.xx.xx]: SASL PLAIN authentication failed: authentication failure ==> mail.warn <== Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: SASL authentication failure: Password verification failed Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: ipname[xx.xx.xx.xx]: SASL PLAIN authentication failed: authentication failure I tried $testsaslauthd -u xxxx -p xxxx 0: OK "Success."

• IIS HTTP Error 403.1 - Forbidden: Execute access is denied

  - by coxymla

  I have a ASP.NET 1.1 application running on IIS 6 / Windows Server 2003. It's our application, but we're trying to specifically replicate a customer's installation so the app folder has been copied entirely from their production server onto our test machine, and then we've created the Virtual Directory and Web Application for IIS manually. The problem I have is that when we access the app, we get the standard IIS security error message: The page cannot be displayed You have attempted to execute a CGI, ISAPI, or other executable program from a directory that does not allow programs to be executed. -------------------------------------------------------------------------------- Please try the following: •Contact the Web site administrator if you believe this directory should allow execute access. HTTP Error 403.1 - Forbidden: Execute access is denied. Internet Information Services (IIS) Now this is pretty standard, except as far as I can see it's not anything so simple. I have checked: IIS user has read access to the directory IIS user and Network Service users have read/write access to the Temporary ASP.NET Files folder Virtual directory is set to the correct version of ASP.NET ASP.NET 1.1 Web Service Extension is allowed Virtual directory has the correct mappings of file extensions and all verbs to the aspnet 1.1 DLL Virtual directory properties allow Scripts and Executables to be run Anonymous access is turned on and the username and password is correct What am I missing?

• Notifying view controller when subview touch events occur.

  - by Nebs

  I have a UIViewController whose view has a custom subview. This custom subview needs to track touch events and report swipe gestures. Currently I put touchesBegan, touchesMoved, touchesEnded and touchesCancelled in the subview class. With some extra logic I am able to get swipe gestures and call my handleRightSwipe and handleLeftSwipe methods. So now when I swipe within the subview it calls its local swipe handling methods. This all works fine. But what I really need is for the handleRightSwipe and handleLeftSwipe methods to be in the view controller. I could leave them in the subview class but then I'd have to bring in all the logic and data as well and that kind of breaks the MVC idea. So my question is is there a clean way to handle this? Essentially I want to keep my touch event methods in the subview so that they only trigger for that specific view. But I also want the view controller to be informed when these touch events (or in this case swipe gestures) occur. Any ideas? Thanks.

• Sharp architecture; Accessing Validation Results

  - by nabeelfarid

  I am exploring Sharp Architecture and I would like to know how to access the validation results after calling Entity.IsValid(). I have two scenarios e.g. 1) If the entity.IsValid() return false, I would like to add the errors to ModelState.AddModelError() collection in my controller. E.g. in the Northwind sample we have an EmployeesController.Create() action when we do employee.IsValid(), how can I get access to the errors? public ActionResult Create(Employee employee) { if (ViewData.ModelState.IsValid && employee.IsValid()) { employeeRepository.SaveOrUpdate(employee); } // .... } [I already know that when an Action method is called, modelbinder enforces validation rules(nhibernate validator attributes) as it parses incoming values and tries to assign them to the model object and if it can't parse the incoming values  then it register those as errors in modelstate for each model object property. But what if i have some custom validation. Thats why we do ModelState.IsValid first.] 2) In my test methods I would like to test the nhibernate validation rules as well. I can do entity.IsValid() but that only returns true/ false. I would like to Assert against the actual error not just true/ false. In my previous projects, I normally use a wrapper Service Layer for Repositories, and instead of calling Repositories method directly from controller, controllers call service layer methods which in turn call repository methods. In my Service Layer all my custom validation rules resides and Service Layer methods throws a custom exception with a NameValueCollection of errors which I can easily add to ModelState in my controller. This way I can also easily implement sophisticated business rules in my service layer as well. I kow sharp architecture also provides a Service Layer project. But what I am interested in and my next question is: How I can use NHibernate Vaidators to implement sophisticated custom business rules (not just null,empty, range etc.) and make Entity.IsValid() to verify those rules too ?

• Maintaining ISAPI Rewrite Path with the ASP.NET tilde (~)

  - by Adam

  My team is upgrading from ASP.NET 3.5 to ASP.NET 4.0. We are currently using Helicon ISAPI Rewrite to map http://localhost/<account-name>/default.aspx to http://localhost/<virtual-directory>/default.aspx?AccountName=<account-name> where <account-name> is a query string variable and <virtual-directory> is a virtual directory (naturally). Before the upgrade the tilde (~) resolved to http://localhost/<account-name>/... (which I want it to do) and after the upgrade the tilde resolves to http://localhost/<virtual-directory>/... which results in an error because the <account-name> query string is required. I'd like to avoid going down the road of replacing everything with relative paths because there are several features in our system that use the entire URL instead of just the relative path. For what it's worth I'm using IIS7 in Windows 7, Visual Studio 2010 with ASP.NET 4.0 and the 64 bit Helicon ISAPI Rewrite. If I switch back to the ASP.NET 3.5 version then it still works fine (leading me to believe nothing changed in IIS unless it's within the 4.0 app pool - when I switch back and forth between 3.5 and 4.0 I have to change the app pool in IIS). Any ideas? Thanks in advance!

• BindAttribute, Exclude nested properties for complex types

  - by David Board

  I have a 'Stream' model: public class Stream { public int ID { get; set; } [Required] [StringLength(50, ErrorMessage = "Stream name cannot be longer than 50 characters.")] public string Name { get; set; } [Required] [DataType(DataType.Url)] public string URL { get; set; } [Required] [Display(Name="Service")] public int ServiceID { get; set; } public virtual Service Service { get; set; } public virtual ICollection<Event> Events { get; set; } public virtual ICollection<Monitor> Monitors { get; set; } public virtual ICollection<AlertRule> AlertRules { get; set; } } For the 'create' view for this model, I have made a view model to pass some additional information to the view: public class StreamCreateVM { public Stream Stream { get; set; } public SelectList ServicesList { get; set; } public int SelectedService { get; set; } } Here is my create post action: [HttpPost] [ValidateAntiForgeryToken] public ActionResult Create([Bind(Include="Stream, Stream.Name, Stream.ServiceID, SelectedService")] StreamCreateVM viewModel) { if (ModelState.IsValid) { db.Streams.Add(viewModel.Stream); db.SaveChanges(); return RedirectToAction("Index", "Service", new { id = viewModel.Stream.ServiceID }); } return View(viewModel); } Now, this all works, apart from the [Bind(Include="Stream, Stream.Name, Stream.ServiceID, SelectedService")] bit. I can't seem to Include or Exclude properties within a nested object.

• Why I am getting a Heap Corruption Error?

  - by vaidya.atul

  I am new to C++. I am getting HEAP CORRUPTION ERROR. Any help will be highly appreciated. Below is my code class CEntity { //some member variables CEntity(string section1,string section2); CEntity(); virtual ~CEntity(); //pure virtual function .. virtual CEntity* create()const =0; }; I derive CLine from CEntity as below class CLine:public CEntity { // Again some variables ... // Constructor and destructor CLine(string section1,string section2); CLine(); ~CLine(); CLine* Create() const; } // CLine Implementation CLine::CLine(string section1,string section2):CEntity(section1,section2){}; CLine::CLine(); CLine* CLine::create()const{return new CLine();} I have another class CReader which uses CLine object and populates it in a multimap as below class CReader { public: CReader(); ~CReader(); multimap<int,CEntity*>m_data_vs_entity; }; //CReader Implementation CReader::CReader() { m_data_vs_entity.clear(); }; CReader::~CReader() { multimap<int,CEntity*>::iterator iter; for(iter = m_data_vs_entity.begin();iter!=m_data_vs_entity.end();iter++) { CEntity* current_entity = iter->second; if(current_entity) delete current_entity; } m_data_vs_entity.clear(); } I am reading the data from a file and then populating the CLine Class.The map gets populated in a function of CReader class. Since CEntity has a virtual destructor, I hope the piece of code in CReader's destructor should work. In fact, it does work for small files but I get HEAP CORRUPTION ERROR while working with bigger files. If there is something fundamentally wrong, then, please help me find it, as I have been scratching my head for quit some time now. Thanks in advance and awaiting reply, Regards, Atul

• Difference between GL10 and GLES10 on Android

  - by kayahr

  The GLSurfaceView.Renderer interface of the Android SDK gives me a GL interface as parameter which has the type GL10. This interface is implemented by some private internal jni wrapper class. But there is also the class GLES10 where all the GL methods are available as static methods. Is there an important difference between them? So what if I ignore the gl parameter of onDrawFrame and instead use the static methods of GLES10 everywhere? Here is an example. Instead of doing this: void onDrawFrame(GL10 gl) { drawSomething(gl); } void drawSomething(GL10 gl) { gl.glLoadIdentity(); ... } I could do this: void onDrawFrame(GL10 gl) { drawSomething(); } void drawSomething() { GLES10.glLoadIdentity(); ... } The advantage is that I don't have to pass the GL context to all called methods. But even it it works (And it works, I tried it) I wonder if there are any disadvantages and reasons to NOT do it like that.

• 'Must Override a Superclass Method' Errors after importing a project into Eclipse

  - by Tim H

  Anytime I have to re-import my projects into Eclipse (if I reinstalled Eclipse, or changed the location of the projects), almost all of my overridden methods are not formatted correctly, causing the error 'The method ?????????? must override a superclass method'. It may be noteworthy to mention this is with Android projects - for whatever reason, the method argument values are not always populated, so I have to manually populate them myself. For instance: list.setOnCreateContextMenuListener(new OnCreateContextMenuListener() { public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { //These arguments have their correct names } }); will be initially populated like this: list.setOnCreateContextMenuListener(new OnCreateContextMenuListener() { public void onCreateContextMenu(ContextMenu arg1, View arg2, ContextMenuInfo arg3) { //This methods arguments were not automatically provided } }); The odd thing is, if I remove my code, and have Eclipse automatically recreate the method, it uses the same argument names I already had, so I don't really know where the problem is, other then it auto-formatting the method for me. This becomes quite a pain having to manually recreate ALL my overridden methods by hand. If anyone can explain why this happens or how to fix it .. I would be very happy. Maybe it is due to the way I am formatting the methods, which are inside an argument of another method?
