System failure - need diagnostic recommendation

- by Ladislav Mrnka

I have big problem with my computer. Configuration is: Intel i7 + 6x2GB OCZ DDR3 Motheboard: Asus P6T Deluxe V2, HDD controller configured to AHCI Main drive: OCZ Vertex 2 (SSD) - contains all installed programs and system Second drive: Samsung SpinPoint - contains User profiles, ProgramData, virtual machines and databases Third drive: Samsung SpinPoint - data drive + backups OS: Windows 7 Ultimate x64 I have never had any problem with this computer until now. During weekend my computer completely crashed without any reason. Each time I tried to boot to Windows I got BSOD with message BAD_SYSTEM_CONFIG_INFO and automatic restart (I didn't install any new SW or HW). But after restart main OCZ drive was disconnected (not detected by BIOS). When I turned off and on computer, the drive was again connected. It also happend every single time I tried to repair installation somehow. It ended with some error and after restart drive was disconnected. The only thing which worked was format + fresh install. After installing almost everything I wanted to install Visual Studio 2010 Ultimate (complete installation without SQL Server Express). During installation of VS itself I always get BSOD - it is too fast so I'm not able to read description. After restart it searches for all disk drives for really long time and sometimes it changes boot drive so the system is not able to start - Bootmgr not found. After reconfiguring BIOS the system starts. There is no event describing the failure in Event viewer. Installing VS 2010 is absolutely necessary for me. I need help with diagnostic. I need to find where is the problem - I expect that the problem is in OCZ drive or in HDD controller on motherboard but I don't know how to find it. All components still have valid warranty. Can you recommend me some approach or tools to find the problem? Edit: I'm still looking for source of the problem. New information is that Windows are not able to perform check disk (Chkdsk) on the SSD system drive. After restarting it always starts checking drive and in part where files are checked it fails with BSOD - BAD_SYSTEM_CONFIG_INFO. After next restart and skipping check disk tests the system runs.

How to tune system settings for mongoDB on Linux?

- by jsh

Trying to squeeze a lot out of one question here -- please bear with me. Although the MongoDB man pages make several useful recommendations about system settings like ulimit (http://docs.mongodb.org/manual/reference/ulimit/), and other production factors (http://docs.mongodb.org/manual/administration/production-notes/) they seem mysteriously silent on things like virtual memory and swap settings. The closest we get to a hint is that "...the operating system’s virtual memory subsystem manages MongoDB’s memory..." (http://docs.mongodb.org/manual/faq/fundamentals/#does-mongodb-require-a-lot-of-ram). Running the same job - high writes and high reads on about 10,000,000 records in a single collection -- on my 4-processor, 4GB RAM macbook and an 8-core ubuntu box with 64GB RAM I saw dramatically WORSE read performance on the linux box with factory settings, and could hear the disk constantly spinning, indicating high I/O and presumably swapping. Yes, other things were happening on the box, but there was plenty of free RAM, disk space, etc.; furthermore, I did not see evidence that Mongo was expanding to take advantage of all that free RAM as it is touted to do. Linux box default settings were as follows: vm.swappiness =60 vm.dirty_background_ratio = 10 vm.dirty_ratio = 20 vm.dirty_expire_centisecs =3000 vm.dirty_writeback_centisecs=500 I hazarded some guesses looking at docs and blogs for other types of databases (Oracle, MYSQL, etc.), experimented, and adjusted as below. vm.swappiness=10 vm.dirty_background_ratio=5 vm.dirty_ratio=5 vm.dirty_writeback_centisecs=250 vm.dirty_expire_centisecs=500 I saw some immediate apparent improvements in read time. However, when I ran my test jobs again, read performance continued to be painfully sluggish during heavy writes. Then, I REBUILT the collection from an available data source - and suddenly I can read at 1ms or less per record WHILE doing the write job! So the question is really two-fold: 1) What are appropriate VM settings for MongoDB on Linux? 2) (bonus) Does Mongo do some checking or optimization with the OS while data is being built? In other words, if I have built a large data set with suboptimal VM or I/O settings, does Mongo make assumptions during the memory-mapping process that will fail to take advantage of optimizations down the road? Obviously I don't fully grok memory mapping under the hood (I was hoping I wouldn't have to). Any help appreciated...thanks! -j

Reviews Cheyney Group Marketing: What accounting softwares are available in the market for small businesses?

- by user225556

Accounting is the language of business, and good accounting software can save you hundreds of hours at the business equivalent of Berlitz. There's no substitute for an accounting pro who knows the ins and outs of tax law, but today's desktop packages can help you with everything from routine bookkeeping to payroll, taxes, and planning. Each package also produces files that you can hand off to an accountant as needed. Small-business managers have more accounting software options than ever, including subscription Web-based options that don't require their users to install or update software. Many businesses, however--including those that need to track large inventories or client databases, and those that prefer not to entrust their data to the cloud--may be happier with a desktop tool. We looked at three general-purpose, small-business accounting packages: Acclivity AccountEdgePro 2012 (both the product and the company were previously called MYOB), Intuit QuickBooks Premier 2012, and Sage's Sage 50 Complete 2013 (the successor to Peachtree Complete). All three packages offer a solid array of tools for tracking income and expenses, invoicing, managing payroll, and creating reports. These full-featured and highly mature programs don't come cheap. Acclivity AccountEdge Pro, at $299, is the least expensive; and prices climb if you opt to use common time-saving add-ons such as payroll services, or if you add licenses for multiple user accounts. All three are solid on the basics, but they have distinct differences in style and focus. The more you know about your accounting requirements, the more closely you'll want to look at the software you're thinking of buying. Sage 50 Complete should appeal most to people who understand the fine points of accounting and can use the product's many customization features (especially for businesses that manage inventory). QuickBooks works hard to appeal to newbies who need only the basics and might be intimidated by the level of detail and technical language exposed in the other two packages. At the same time, it also has a slew of third-party add-ons that meet specific needs and greatly expand its capabilities. AccountEdge Pro balances accessibility with a strong feature set at an affordable price. It's especially suitable for businesses that need to provide simultaneous access to multiple users.

Need help recovering a corrupt SQL database

- by user570079

I have a very special case that I have been working on for several days. I have a very large SQL Server 2008 database (about 2 TB) that contains 500 filegroups to support very large partitioned tables. Recently we had a catastophic failure on one of the drive and lost several filegroups and the database became in-accessible. We have been doing filegroup backups on a daily basis, but due to other issues, we lost our most recent backup of the log and the primary filegroup. We have all the data backed up but the primary filegroup backup is old. There have been no schema changes since the primary filegroup backup, but the lsn's are now all out of sync and we cannot recover the data. I have tried everything I could think of (and have tried just about every trick and hack I could google) but I still end up at the same point where I get messages saying that the files for filegroup x do not match the primary filegroup. I am now at the point of trying to edit the system tables (we have a separate temporary environment to do this so we are not worried about corrupting any production databases). I have tried updated sys.sysdbreg, sys.sysbrickfiles, and sys.sysprufiles to try to trick SQL into thinking all the files are online, but a "Select * From OPENROWSET(TABLE DBPROP, 5)" shows a different database state from what I see in sys.sysdbreg. I am now thinking I need to somehow edit the headers of the actual data files to try to line up the lsn's with the primary. I appreciate any help anyone can give me here, but please do not respond with things like "you are not supposed to do edit mdf, ndf files...." or "see msdn article....", etc. This is an advanced emergency case and I need a real hack so we can just get to the data in this corrupt database and export to a fresh new database. I know there is a way to do this, but not knowing what the DBPROP system functions does (i.e. does it look at system tables or does it actually open the file) is keeping me from trying to figure out how to fool SQL into allowing me to read these files. Thanks for any help.

jqgrid with asp.net webmethod and json working with sorting, paging, searching and LINQ

- by aimlessWonderer

THIS WORKS! Most topics covering jqgrid and asp.net seem to relate to just receiving JSON, or working in the MVC framework, or utilizing other handlers or web services... but not many dealt with actually passing parameters back to an actual webmethod in the codebehind. Furthermore, scarce are the examples that contain successful implementation the AJAX paging, sorting, or searching along with LINQ to SQL for asp.net jqGrid. Below is a working example that may help others who need help to pass parameters to jqGrid in order to have correct paging, sorting, filtering.. it uses pieces from here and there... ================================================== First, THE JAVASCRIPT <script type="text/javascript"> $(document).ready(function() { var grid = $("#list"); $("#list").jqGrid({ // setup custom parameter names to pass to server prmNames: { search: "isSearch", nd: null, rows: "numRows", page: "page", sort: "sortField", order: "sortOrder" }, // add by default to avoid webmethod parameter conflicts postData: { searchString: '', searchField: '', searchOper: '' }, // setup ajax call to webmethod datatype: function(postdata) { mtype: "GET", $.ajax({ url: 'PageName.aspx/getGridData', type: "POST", contentType: "application/json; charset=utf-8", data: JSON.stringify(postdata), dataType: "json", success: function(data, st) { if (st == "success") { var grid = jQuery("#list")[0]; grid.addJSONData(JSON.parse(data.d)); } }, error: function() { alert("Error with AJAX callback"); } }); }, // this is what jqGrid is looking for in json callback jsonReader: { root: "rows", page: "page", total: "totalpages", records: "totalrecords", cell: "cell", id: "id", //index of the column with the PK in it userdata: "userdata", repeatitems: true }, colNames: ['Id', 'First Name', 'Last Name'], colModel: [ { name: 'id', index: 'id', width: 55, search: false }, { name: 'fname', index: 'fname', width: 200, searchoptions: { sopt: ['eq', 'ne', 'cn']} }, { name: 'lname', index: 'lname', width: 200, searchoptions: { sopt: ['eq', 'ne', 'cn']} } ], rowNum: 10, rowList: [10, 20, 30], pager: jQuery("#pager"), sortname: "fname", sortorder: "asc", viewrecords: true, caption: "Grid Title Here" }).jqGrid('navGrid', '#pager', { edit: false, add: false, del: false }, {}, // default settings for edit {}, // add {}, // delete { closeOnEscape: true, closeAfterSearch: true}, //search {} ) }); </script> ================================================== Second, THE C# WEBMETHOD [WebMethod] public static string getGridData(int? numRows, int? page, string sortField, string sortOrder, bool isSearch, string searchField, string searchString, string searchOper) { string result = null; MyDataContext db = null; try { //--- retrieve the data db = new MyDataContext("my connection string path"); var query = from u in db.TBL_USERs select u; //--- determine if this is a search filter if (isSearch) { searchOper = getOperator(searchOper); // need to associate correct operator to value sent from jqGrid string whereClause = String.Format("{0} {1} {2}", searchField, searchOper, "@" + searchField); //--- associate value to field parameter Dictionary<string, object> param = new Dictionary<string, object>(); param.Add("@" + searchField, searchString); query = query.Where(whereClause, new object[1] { param }); } //--- setup calculations int pageIndex = page ?? 1; //--- current page int pageSize = numRows ?? 10; //--- number of rows to show per page int totalRecords = query.Count(); //--- number of total items from query int totalPages = (int)Math.Ceiling((decimal)totalRecords / (decimal)pageSize); //--- number of pages //--- filter dataset for paging and sorting IQueryable<TBL_USER> orderedRecords = query.OrderBy(sortfield); IEnumerable<TBL_USER> sortedRecords = orderedRecords.ToList(); if (sortorder == "desc") sortedRecords= sortedRecords.Reverse(); sortedRecords= sortedRecords .Skip((pageIndex - 1) * pageSize) //--- page the data .Take(pageSize); //--- format json var jsonData = new { totalpages = totalPages, //--- number of pages page = pageIndex, //--- current page totalrecords = totalRecords, //--- total items rows = ( from row in sortedRecords select new { i = row.USER_ID, cell = new string[] { row.USER_ID.ToString(), row.FNAME.ToString(), row.LNAME } } ).ToArray() }; result = Newtonsoft.Json.JsonConvert.SerializeObject(jsonData); } catch (Exception ex) { Debug.WriteLine(ex); } finally { if (db != null) db.Dispose(); } return result; } ================================================== Third, NECESSITIES In order to have dynamic OrderBy clauses in the LINQ, I had to pull in a class to my AppCode folder called 'Dynamic.cs'. You can retrieve the file from downloading here. You will find the file in the "DynamicQuery" folder. That file will give you the ability to utilized dynamic ORDERBY clause since we don't know what column we're filtering by except on the initial load. To serialize the JSON back from the C-sharp to the JS, I incorporated the James Newton-King JSON.net DLL found here : http://json.codeplex.com/releases/view/37810. After downloading, there is a "Newtonsoft.Json.Compact.dll" which you can add in your Bin folder as a reference Here's my USING's block using System; using System.Collections; using System.Collections.Generic; using System.Linq; using System.Web.UI.WebControls; using System.Web.Services; using System.Linq.Dynamic; For the Javascript references, I'm using the following scripts in respective order in case that helps some folks: 1) jquery-1.3.2.min.js ... 2) jquery-ui-1.7.2.custom.min.js ... 3) json.min.js ... 4) i18n/grid.locale-en.js ... 5) jquery.jqGrid.min.js For the CSS, I'm using jqGrid's necessities as well as the jQuery UI Theme: 1) jquery_theme/jquery-ui-1.7.2.custom.css ... 2) ui.jqgrid.css The key to getting the parameters from the JS to the WebMethod without having to parse an unserialized string on the backend or having to setup some JS logic to switch methods for different numbers of parameters was this block postData: { searchString: '', searchField: '', searchOper: '' }, Those parameters will still be set correctly when you actually do a search and then reset to empty when you "reset" or want the grid to not do any filtering Hope this helps some others!!!! Please reply if you find major issues or ways of refactoring or doing better that I haven't considered.

SQL SERVER – Enumerations in Relational Database – Best Practice

- by pinaldave

Marko Parkkola This article has been submitted by Marko Parkkola, Data systems designer at Saarionen Oy, Finland. Marko is excellent developer and always thinking at next level. You can read his earlier comment which created very interesting discussion here: SQL SERVER- IF EXISTS(Select null from table) vs IF EXISTS(Select 1 from table). I must express my special thanks to Marko for sending this best practice for Enumerations in Relational Database. He has really wrote excellent piece here and welcome comments here. Enumerations in Relational Database This is a subject which is very basic thing in relational databases but often not very well understood and sometimes badly implemented. There are of course many ways to do this but I concentrate only two cases, one which is “the right way” and one which is definitely wrong way. The concept Let’s say we have table Person in our database. Person has properties/fields like Firstname, Lastname, Birthday and so on. Then there’s a field that tells person’s marital status and let’s name it the same way; MaritalStatus. Now MaritalStatus is an enumeration. In C# I would definitely make it an enumeration with values likes Single, InRelationship, Married, Divorced. Now here comes the problem, SQL doesn’t have enumerations. The wrong way This is, in my opinion, absolutely the wrong way to do this. It has one upside though; you’ll see the enumeration’s description instantly when you do simple SELECT query and you don’t have to deal with mysterious values. There’s plenty of downsides too and one would be database fragmentation. Consider this (I’ve left all indexes and constraints out of the query on purpose). CREATE TABLE [dbo].[Person] ( [Firstname] NVARCHAR(100), [Lastname] NVARCHAR(100), [Birthday] datetime, [MaritalStatus] NVARCHAR(10) ) You have nvarchar(20) field in the table that tells the marital status. Obvious problem with this is that what if you create a new value which doesn’t fit into 20 characters? You’ll have to come and alter the table. There are other problems also but I’ll leave those for the reader to think about. The correct way Here’s how I’ve done this in many projects. This model still has one problem but it can be alleviated in the application layer or with CHECK constraints if you like. First I will create a namespace table which tells the name of the enumeration. I will add one row to it too. I’ll write all the indexes and constraints here too. CREATE TABLE [CodeNamespace] ( [Id] INT IDENTITY(1, 1), [Name] NVARCHAR(100) NOT NULL, CONSTRAINT [PK_CodeNamespace] PRIMARY KEY ([Id]), CONSTRAINT [IXQ_CodeNamespace_Name] UNIQUE NONCLUSTERED ([Name]) ) GO INSERT INTO [CodeNamespace] SELECT 'MaritalStatus' GO Then I create a table that holds the actual values and which reference to namespace table in order to group the values under different namespaces. I’ll add couple of rows here too. CREATE TABLE [CodeValue] ( [CodeNamespaceId] INT NOT NULL, [Value] INT NOT NULL, [Description] NVARCHAR(100) NOT NULL, [OrderBy] INT, CONSTRAINT [PK_CodeValue] PRIMARY KEY CLUSTERED ([CodeNamespaceId], [Value]), CONSTRAINT [FK_CodeValue_CodeNamespace] FOREIGN KEY ([CodeNamespaceId]) REFERENCES [CodeNamespace] ([Id]) ) GO -- 1 is the 'MaritalStatus' namespace INSERT INTO [CodeValue] SELECT 1, 1, 'Single', 1 INSERT INTO [CodeValue] SELECT 1, 2, 'In relationship', 2 INSERT INTO [CodeValue] SELECT 1, 3, 'Married', 3 INSERT INTO [CodeValue] SELECT 1, 4, 'Divorced', 4 GO Now there’s four columns in CodeValue table. CodeNamespaceId tells under which namespace values belongs to. Value tells the enumeration value which is used in Person table (I’ll show how this is done below). Description tells what the value means. You can use this, for example, column in UI’s combo box. OrderBy tells if the values needs to be ordered in some way when displayed in the UI. And here’s the Person table again now with correct columns. I’ll add one row here to show how enumerations are to be used. CREATE TABLE [dbo].[Person] ( [Firstname] NVARCHAR(100), [Lastname] NVARCHAR(100), [Birthday] datetime, [MaritalStatus] INT ) GO INSERT INTO [Person] SELECT 'Marko', 'Parkkola', '1977-03-04', 3 GO Now I said earlier that there is one problem with this. MaritalStatus column doesn’t have any database enforced relationship to the CodeValue table so you can enter any value you like into this field. I’ve solved this problem in the application layer by selecting all the values from the CodeValue table and put them into a combobox / dropdownlist (with Value field as value and Description as text) so the end user can’t enter any illegal values; and of course I’ll check the entered value in data access layer also. I said in the “The wrong way” section that there is one benefit to it. In fact, you can have the same benefit here by using a simple view, which I schema bound so you can even index it if you like. CREATE VIEW [dbo].[Person_v] WITH SCHEMABINDING AS SELECT p.[Firstname], p.[Lastname], p.[BirthDay], c.[Description] MaritalStatus FROM [dbo].[Person] p JOIN [dbo].[CodeValue] c ON p.[MaritalStatus] = c.[Value] JOIN [dbo].[CodeNamespace] n ON n.[Id] = c.[CodeNamespaceId] AND n.[Name] = 'MaritalStatus' GO -- Select from View SELECT * FROM [dbo].[Person_v] GO This is excellent write up byMarko Parkkola. Do you have this kind of design setup at your organization? Let us know your opinion.

Windows Azure: Announcing Support for Windows Server 2012 R2 + Some Nice Price Cuts

- by ScottGu

Today we released some great updates to Windows Azure: Virtual Machines: Support for Windows Server 2012 R2 Cloud Services: Support for Windows Server 2012 R2 and .NET 4.5.1 Windows Azure Pack: Use Windows Azure features on-premises using Windows Server 2012 R2 Price Cuts: Up to 22% Price Reduction on Memory-Intensive Instances Below are more details about each of the improvements: Virtual Machines: Support for Windows Server 2012 R2 This morning we announced the release of Windows Server 2012 R2 – which is a fantastic update to Windows Server and includes a ton of great enhancements. This morning we are also excited to announce that the general availability image of Windows Server 2012 RC is now supported on Windows Azure. Windows Azure is the first cloud provider to offer the final release of Windows Server 2012 R2, and it is incredibly easy to launch your own Windows Server 2012 R2 instance with it. To create a new Windows Server 2012 R2 instance simply choose New->Compute->Virtual Machine within the Windows Azure Management Portal. You can select the “Windows Server 2012 R2” image and create a new Virtual Machine using the “Quick Create” option: Or alternatively click the “From Gallery” option if you want to customize even more configuration options (endpoints, remote powershell, availability set, etc): Creating and instantiating a new Virtual Machine on Windows Azure is very fast. In fact, the Windows Server 2012 R2 image now deploys and runs 30% faster than previous versions of Windows Server. Once the VM is deployed you can drill into it to track its health and manage its settings: Clicking the “Connect” button allows you to remote desktop into the VM – at which point you can customize and manage it as a full administrator however you want: If you haven’t tried Windows Server 2012 R2 yet – give it a try with Windows Azure. There is no easier way to get an instance of it up and running! Cloud Services: Support for using Windows Server 2012 R2 with Web and Worker Roles Today’s Windows Azure release also allows you to now use Windows Server 2012 R2 and .NET 4.5.1 within Web and Worker Roles within Cloud Service based applications. Enabling this is easy. You can configure existing existing Cloud Service application to use Windows Server 2012 R2 by updating your Cloud Service Configuration File (.cscfg) to use the new “OS Family 4” setting: Or alternatively you can use the Windows Azure Management Portal to update cloud services that are already deployed on Windows Azure. Simply choose the configure tab on them and select Windows Server 2012 R2 in the Operating System Family dropdown: The approaches above enable you to immediately take advantage of Windows Server 2012 R2 and .NET 4.5.1 and all the great features they provide. Windows Azure Pack: Use Windows Azure features on Windows Server 2012 R2 Today we also made generally available the Windows Azure Pack, which is a free download that enables you to run Windows Azure Technology within your own datacenter, an on-premises private cloud environment, or with one of our service provider/hosting partners who run Windows Server. Windows Azure Pack enables you to use a management portal that has the exact same UI as the Windows Azure Management Portal, and within which you can create and manage Virtual Machines, Web Sites, and Service Bus – all of which can run on Windows Server and System Center.

New MySQL Cluster 7.3 Previews: Foreign Keys, NoSQL Node.js API and Auto-Tuned Clusters

- by Mat Keep

At this weeks MySQL Connect conference, Oracle previewed an exciting new wave of developments for MySQL Cluster, further extending its simplicity and flexibility by expanding the range of use-cases, adding new NoSQL options, and automating configuration. What’s new: Development Release 1: MySQL Cluster 7.3 with Foreign Keys Early Access “Labs” Preview: MySQL Cluster NoSQL API for Node.js Early Access “Labs” Preview: MySQL Cluster GUI-Based Auto-Installer In this blog, I'll introduce you to the features being previewed. Review the blogs listed below for more detail on each of the specific features discussed. Save the date!: A live webinar is scheduled for Thursday 25th October at 0900 Pacific Time / 1600UTC where we will discuss each of these enhancements in more detail. Registration will be open soon and published to the MySQL webinars page MySQL Cluster 7.3: Development Release 1 The first MySQL Cluster 7.3 Development Milestone Release (DMR) previews Foreign Keys, bringing powerful new functionality to MySQL Cluster while eliminating development complexity. Foreign Key support has been one of the most requested enhancements to MySQL Cluster – enabling users to simplify their data models and application logic – while extending the range of use-cases for both custom projects requiring referential integrity and packaged applications, such as eCommerce, CRM, CMS, etc. Implementation The Foreign Key functionality is implemented directly within the MySQL Cluster data nodes, allowing any client API accessing the cluster to benefit from them – whether they are SQL or one of the NoSQL interfaces (Memcached, C++, Java, JPA, HTTP/REST or the new Node.js API - discussed later.) The core referential actions defined in the SQL:2003 standard are implemented: CASCADE RESTRICT NO ACTION SET NULL In addition, the MySQL Cluster implementation supports the online adding and dropping of Foreign Keys, ensuring the Cluster continues to serve both read and write requests during the operation. This represents a further enhancement to MySQL Cluster's support for on0line schema changes, ie adding and dropping indexes, adding columns, etc. Read this blog for a demonstration of using Foreign Keys with MySQL Cluster. Getting Started with MySQL Cluster 7.3 DMR1: Users can download either the source or binary and evaluate the MySQL Cluster 7.3 DMR with Foreign Keys now! (Select the Development Release tab). MySQL Cluster NoSQL API for Node.js Node.js is hot! In a little over 3 years, it has become one of the most popular environments for developing next generation web, cloud, mobile and social applications. Bringing JavaScript from the browser to the server, the design goal of Node.js is to build new real-time applications supporting millions of client connections, serviced by a single CPU core. Making it simple to further extend the flexibility and power of Node.js to the database layer, we are previewing the Node.js Javascript API for MySQL Cluster as an Early Access release, available for download now from http://labs.mysql.com/. Select the following build: MySQL-Cluster-NoSQL-Connector-for-Node-js Alternatively, you can clone the project at the MySQL GitHub page. Implemented as a module for the V8 engine, the new API provides Node.js with a native, asynchronous JavaScript interface that can be used to both query and receive results sets directly from MySQL Cluster, without transformations to SQL. Figure 1: MySQL Cluster NoSQL API for Node.js enables end-to-end JavaScript development Rather than just presenting a simple interface to the database, the Node.js module integrates the MySQL Cluster native API library directly within the web application itself, enabling developers to seamlessly couple their high performance, distributed applications with a high performance, distributed, persistence layer delivering 99.999% availability. The new Node.js API joins a rich array of NoSQL interfaces available for MySQL Cluster. Whichever API is chosen for an application, SQL and NoSQL can be used concurrently across the same data set, providing the ultimate in developer flexibility. Get started with MySQL Cluster NoSQL API for Node.js tutorial MySQL Cluster GUI-Based Auto-Installer Compatible with both MySQL Cluster 7.2 and 7.3, the Auto-Installer makes it simple for DevOps teams to quickly configure and provision highly optimized MySQL Cluster deployments – whether on-premise or in the cloud. Implemented with a standard HTML GUI and Python-based web server back-end, the Auto-Installer intelligently configures MySQL Cluster based on application requirements and auto-discovered hardware resources Figure 2: Automated Tuning and Configuration of MySQL Cluster Developed by the same engineering team responsible for the MySQL Cluster database, the installer provides standardized configurations that make it simple, quick and easy to build stable and high performance clustered environments. The auto-installer is previewed as an Early Access release, available for download now from http://labs.mysql.com/, by selecting the MySQL-Cluster-Auto-Installer build. You can read more about getting started with the MySQL Cluster auto-installer here. Watch the YouTube video for a demonstration of using the MySQL Cluster auto-installer Getting Started with MySQL Cluster If you are new to MySQL Cluster, the Getting Started guide will walk you through installing an evaluation cluster on a singe host (these guides reflect MySQL Cluster 7.2, but apply equally well to 7.3 and the Early Access previews).

Database model for keeping track of likes/shares/comments on blog posts over time

- by gage

My goal is to keep track of the popular posts on different blog sites based on social network activity at any given time. The goal is not to simply get the most popular now, but instead find posts that are popular compared to other posts on the same blog. For example, I follow a tech blog, a sports blog, and a gossip blog. The tech blog gets waaay more readership than the other two blogs, so in raw numbers every post on the tech blog will always out number views on the other two. So lets say the average tech blog post gets 500 facebook likes and the other two get an average of 50 likes per post. Then when there is a sports blog post that has 200 fb likes and a gossip blog post with 300 while the tech blog posts today have 500 likes I want to highlight the sports and gossip blog posts (more likes than average vs tech blog with more # of likes but just average for the blog) The approach I am thinking of taking is to make an entry in a database for each blog post. Every x minutes (say every 15 minutes) I will check how many likes/shares/comments an entry has received on all the social networks (facebook, twitter, google+, linkeIn). So over time there will be a history of likes for each blog post, i.e post 1234 after 15 min: 10 fb likes, 4 tweets, 6 g+ after 30 min: 15 fb likes, 15 tweets, 10 g+ ... ... after 48 hours: 200 fb likes, 25 tweets, 15 g+ By keeping a history like this for each blog post I can know the average number of likes/shares/tweets at any give time interval. So for example the average number of fb likes for all blog posts 48hrs after posting is 50, and a particular post has 200 I can mark that as a popular post and feature/highlight it. A consideration in the design is to be able to easily query the values (likes/shares) for a specific time-frame, i.e. fb likes after 30min or tweets after 24 hrs in-order to compute averages with which to compare against (or should averages be stored in it's own table?) If this approach is flawed or could use improvement please let me know, but it is not my main question. My main question is what should a database scheme for storing this info look like? Assuming that the above approach is taken I am trying to figure out what a database schema for storing the likes over time would look like. I am brand new to databases, in doing some basic reading I see that it is advisable to make a 3NF database. I have come up with the following possible schema. Schema 1 DB Popular Posts Table: Post post_id ( primary key(pk) ) url title Table: Social Activity activity_id (pk) url (fk) type (i.e. facebook,twitter,g+) value timestamp This was my initial instinct (base on my very limited db knowledge). As far as I under stand this schema would be 3NF? I searched for designs of similar database model, and found this question on stackoverflow, http://stackoverflow.com/questions/11216080/data-structure-for-storing-height-and-weight-etc-over-time-for-multiple-users . The scenario in that question is similar (recording weight/height of users overtime). Taking the accepted answer for that question and applying it to my model results in something like: Schema 2 (same as above, but break down the social activity into 2 tables) DB Popular Posts Table: Post post_id (pk) url title Table: Social Measurement measurement_id (pk) post_id (fk) timestamp Table: Social stat stat_id (pk) measurement_id (fk) type (i.e. facebook,twitter,g+) value The advantage I see in schema 2 is that I will likely want to access all the values for a given time, i.e. when making a measurement at 30min after a post is published I will simultaneous check number of fb likes, fb shares, fb comments, tweets, g+, linkedIn. So with this schema it may be easier get get all stats for a measurement_id corresponding to a certain time, i.e. all social stats for post 1234 at time x. Another thought I had is since it doesn't make sense to compare number of fb likes with number of tweets or g+ shares, maybe it makes sense to separate each social measurement into it's own table? Schema 3 DB Popular Posts Table: Post post_id (pk) url title Table: fb_likes fb_like_id (pk) post_id (fk) timestamp value Table: fb_shares fb_shares_id (pk) post_id (fk) timestamp value Table: tweets tweets__id (pk) post_id (fk) timestamp value Table: google_plus google_plus_id (pk) post_id (fk) timestamp value As you can see I am generally lost/unsure of what approach to take. I'm sure this typical type of database problem (storing measurements overtime, i.e temperature statistic) that must have a common solution. Is there a design pattern/model for this, does it have a name? I tried searching for "database periodic data collection" or "database measurements over time" but didn't find anything specific. What would be an appropriate model to solve the needs of this problem?

SQL Developer at Oracle Open World 2012

- by thatjeffsmith

We have a lot going on in San Francisco this fall. One of the most personal exciting bits, for what will be my 4th or 5th Open World, is that this will be my FIRST as a member of Team Oracle. I’ve presented once before, but most years it was just me pressing flesh at the vendor booths. After 3-4 days of standing and talking, you’re ready to just go home and not do anything for a few weeks. This time I’ll have a chance to walk around and talk with our users and get a good idea of what’s working and what’s not. Of course it will be a great opportunity for you to find us and get to know your SQL Developer team! 3.4 miles across and back – thanks Ashley for signing me up for the run! This year is going to be a bit crazy. Work wise I’ll be presenting twice, working a booth, and proctoring several of our Hands-On Labs. The fun parts will be equally crazy though – running across the Bay Bridge (I don’t run), swimming the Bay (I don’t swim), having my wife fly out on Wednesday for the concert, and then our first WhiskyFest on Friday (I do drink whisky though.) But back to work – let’s talk about EVERYTHING you can expect from the SQL Developer team. Booth Hours We’ll have 2 ‘demo pods’ in the Exhibition Hall over at Moscone South. Look for the farm of Oracle booths, we’ll be there under the signs that say ‘SQL Developer.’ There will be several people on hand, mostly developers (yes, they still count as people), who can answer your questions or demo the latest features. Come by and say ‘Hi!’, and let us know what you like and what you think we can do better. Seriously. Monday 10AM – 6PM Tuesday 9:45AM – 6PM Wednesday 9:45AM – 4PM Presentations Stop by for an hour, pull up a chair, sit back and soak in all the SQL Developer goodness. You’ll only have to suffer my bad jokes for two of the presentations, so please at least try to come to the other ones. We’ll be talking about data modeling, migrations, source control, and new features in versions 3.1 and 3.2 of SQL Developer and SQL Developer Data Modeler. Day Time Event Monday 10:454:45 What’s New in SQL Developer Why Move to Oracle Application Express Listener Tueday 10:1511:455:00 Using Subversion in Oracle SQL Developer Data Modeler Oracle SQL Developer Tips & Tricks Database Design with Oracle SQL Developer Data Modeler Wednesday 11:453:30 Migrating Third-Party Databases and Applications to Oracle Exadata 11g Enterprise Options and Management Packs for Developers Hands On Labs (HOLs) The Hands On Labs allow you to come into a classroom environment, sit down at a computer, and run through some exercises. We’ll provide the hardware, software, and training materials. It’s self-paced, but we’ll have several helpers walking around to answer questions and chat up any SQL Developer or database topic that comes to mind. If your employer is sending you to Open World for all that great training, the HOLs are a great opportunity to capitalize on that. They are only 60 minutes each, so you don’t have to worry about burning out. And there’s no homework! Of course, if you do want to take the labs home with you, many are already available via the Developer Day Hands-On Database Applications Developer Lab. You will need your own computer for those, but we’ll take care of the rest. Wednesday PL/SQL Development and Unit Testing with Oracle SQL Developer 10:15 Performance Tuning with Oracle SQL Developer 11:45 Thursday The Soup to Nuts of Data Modeling with Oracle SQL Developer Data Modeler 11:15 Some Parting Advice Always wanted to meet your favorite Oracle authors, speakers, and thought-leaders? Don’t be shy, walk right up to them and introduce yourself. Normal social rules still apply, but at the conference everyone is open and up for meeting and talking with attendees. Just understand if there’s a line that you might only get a minute or two. It’s a LONG conference though, so you’ll have plenty of time to catch up with everyone. If you’re going to be around on Tuesday evening, head on over to the OTN Lounge from 4:30 to 6:30 and hang out for our Tweet Meet. That’s right, all the Oracle nerds on Twitter will be there in one place. Be sure to put your Twitter handle on your name tag so we know who you are!

Using C# 4.0’s DynamicObject as a Stored Procedure Wrapper

- by EltonStoneman

[Source: http://geekswithblogs.net/EltonStoneman] Overview Ignoring the fashion, I still make a lot of use of DALs – typically when inheriting a codebase with an established database schema which is full of tried and trusted stored procedures. In the DAL a collection of base classes have all the scaffolding, so the usual pattern is to create a wrapper class for each stored procedure, giving typesafe access to parameter values and output. DAL calls then looks like instantiate wrapper-populate parameters-execute call: using (var sp = new uspGetManagerEmployees()) { sp.ManagerID = 16; using (var reader = sp.Execute()) { //map entities from the output } } Or rolling it all into a fluent DAL call – which is nicer to read and implicitly disposes the resources: This is fine, the wrapper classes are very simple to handwrite or generate. But as the codebase grows, you end up with a proliferation of very small wrapper classes: The wrappers don't add much other than encapsulating the stored procedure call and giving you typesafety for the parameters. With the dynamic extension in .NET 4.0 you have the option to build a single wrapper class, and get rid of the one-to-one stored procedure to wrapper class mapping. In the dynamic version, the call looks like this: dynamic getUser = new DynamicSqlStoredProcedure("uspGetManagerEmployees", Database.AdventureWorks); getUser.ManagerID = 16; var employees = Fluently.Load<List<Employee>>() .With<EmployeeMap>() .From(getUser); The important difference is that the ManagerId property doesn't exist in the DynamicSqlStoredProcedure class. Declaring the getUser object with the dynamic keyword allows you to dynamically add properties, and the DynamicSqlStoredProcedure class intercepts when properties are added and builds them as stored procedure parameters. When getUser.ManagerId = 16 is executed, the base class adds a parameter call (using the convention that parameter name is the property name prefixed by "@"), specifying the correct SQL Server data type (mapping it from the type of the value the property is set to), and setting the parameter value. Code Sample This is worked through in a sample project on github – Dynamic Stored Procedure Sample – which also includes a static version of the wrapper for comparison. (I'll upload this to the MSDN Code Gallery once my account has been resurrected). Points worth noting are: DynamicSP.Data – database-independent DAL that has all the data plumbing code. DynamicSP.Data.SqlServer – SQL Server DAL, thin layer on top of the generic DAL which adds SQL Server specific classes. Includes the DynamicSqlStoredProcedure base class. DynamicSqlStoredProcedure.TrySetMember. Invoked when a dynamic member is added. Assumes the property is a parameter named after the SP parameter name and infers the SqlDbType from the framework type. Adds a parameter to the internal stored procedure wrapper and sets its value. uspGetManagerEmployees – the static version of the wrapper. uspGetManagerEmployeesTest – test fixture which shows usage of the static and dynamic stored procedure wrappers. The sample uses stored procedures from the AdventureWorks database in the SQL Server 2008 Sample Databases. Discussion For this scenario, the dynamic option is very favourable. Assuming your DAL is itself wrapped by a higher layer, the stored procedure wrapper classes have very little reuse. Even if you're codegening the classes and test fixtures, it's still additional effort for very little value. The main consideration with dynamic classes is that the compiler ignores all the members you use, and evaluation only happens at runtime. In this case where scope is strictly limited that's not an issue – but you're relying on automated tests rather than the compiler to find errors, but that should just encourage better test coverage. Also you can codegen the dynamic calls at a higher level. Performance may be a consideration, as there is a first-time-use overhead when the dynamic members of an object are bound. For a single run, the dynamic wrapper took 0.2 seconds longer than the static wrapper. The framework does a good job of caching the effort though, so for 1,000 calls the dynamc version still only takes 0.2 seconds longer than the static: You don't get IntelliSense on dynamic objects, even for the declared members of the base class, and if you've been using class names as keys for configuration settings, you'll lose that option if you move to dynamics. The approach may make code more difficult to read, as you can't navigate through dynamic members, but you do still get full debugging support. var employees = Fluently.Load<List<Employee>>() .With<EmployeeMap>() .From<uspGetManagerEmployees> ( i => i.ManagerID = 16, x => x.Execute() );

Solaris 11.1: Changes to included FOSS packages

- by alanc

Besides the documentation changes I mentioned last time, another place you can see Solaris 11.1 changes before upgrading is in the online package repository, now that the 11.1 packages have been published to http://pkg.oracle.com/solaris/release/, as the “0.175.1.0.0.24.2” branch. (Oracle Solaris Package Versioning explains what each field in that version string means.) When you’re ready to upgrade to the packages from either this repo, or the support repository, you’ll want to first read How to Update to Oracle Solaris 11.1 Using the Image Packaging System by Pete Dennis, as there are a couple issues you will need to be aware of to do that upgrade, several of which are due to changes in the Free and Open Source Software (FOSS) packages included with Solaris, as I’ll explain in a bit. Solaris 11 can update more readily than Solaris 10 In the Solaris 10 and older update models, the way the updates were built constrained what changes we could make in those releases. To change an existing SVR4 package in those releases, we created a Solaris Patch, which applied to a given version of the SVR4 package and replaced, added or deleted files in it. These patches were released via the support websites (originally SunSolve, now My Oracle Support) for applying to existing Solaris 10 installations, and were also merged into the install images for the next Solaris 10 update release. (This Solaris Patches blog post from Gerry Haskins dives deeper into that subject.) Some of the restrictions of this model were that package refactoring, changes to package dependencies, and even just changing the package version number, were difficult to do in this hybrid patch/OS update model. For instance, when Solaris 10 first shipped, it had the Xorg server from X11R6.8. Over the first couple years of update releases we were able to keep it up to date by replacing, adding, & removing files as necessary, taking it all the way up to Xorg server release 1.3 (new version numbering begun after the X11R7 split of the X11 tree into separate modules gave each module its own version). But if you run pkginfo on the SUNWxorg-server package, you’ll see it still displayed a version number of 6.8, confusing users as to which version was actually included. We stopped upgrading the Xorg server releases in Solaris 10 after 1.3, as later versions added new dependencies, such as HAL, D-Bus, and libpciaccess, which were very difficult to manage in this patching model. (We later got libpciaccess to work, but HAL & D-Bus would have been much harder due to the greater dependency tree underneath those.) Similarly, every time the GNOME team looked into upgrading Solaris 10 past GNOME 2.6, they found these constraints made it so difficult it wasn’t worthwhile, and eventually GNOME’s dependencies had changed enough it was completely infeasible. Fortunately, this worked out for both the X11 & GNOME teams, with our management making the business decision to concentrate on the “Nevada” branch for desktop users - first as Solaris Express Desktop Edition, and later as OpenSolaris, so we didn’t have to fight to try to make the package updates fit into these tight constraints. Meanwhile, the team designing the new packaging system for Solaris 11 was seeing us struggle with these problems, and making this much easier to manage for both the development teams and our users was one of their big goals for the IPS design they were working on. Now that we’ve reached the first update release to Solaris 11, we can start to see the fruits of their labors, with more FOSS updates in 11.1 than we had in many Solaris 10 update releases, keeping software more up to date with the upstream communities. Of course, just because we can more easily update now, doesn’t always mean we should or will do so, it just removes the package system limitations from forcing the decision for us. So while we’ve upgraded the X Window System in the 11.1 release from X11R7.6 to 7.7, the Solaris GNOME team decided it was not the right time to try to make the jump from GNOME 2 to GNOME 3, though they did update some individual components of the desktop, especially those with security fixes like Firefox. In other parts of the system, decisions as to what to update were prioritized based on how they affected other projects, or what customer requests we’d gotten for them. So with all that background in place, what packages did we actually update or add between Solaris 11.0 and 11.1? Core OS Functionality One of the FOSS changes with the biggest impact in this release is the upgrade from Grub Legacy (0.97) to Grub 2 (1.99) for the x64 platform boot loader. This is the cause of one of the upgrade quirks, since to go from Solaris 11.0 to 11.1 on x64 systems, you first need to update the Boot Environment tools (such as beadm) to a new version that can handle boot environments that use the Grub2 boot loader. System administrators can find the details they need to know about the new Grub in the Administering the GRand Unified Bootloader chapter of the Booting and Shutting Down Oracle Solaris 11.1 Systems guide. This change was necessary to be able to support new hardware coming into the x64 marketplace, including systems using UEFI firmware or booting off disk drives larger than 2 terabytes. For both platforms, Solaris 11.1 adds rsyslog as an optional alternative to the traditional syslogd, and OpenSCAP for checking security configuration settings are compliant with site policies. Note that the support repo actually has newer versions of BIND & fetchmail than the 11.1 release, as some late breaking critical fixes came through from the community upstream releases after the Solaris 11.1 release was frozen, and made their way to the support repository. These are responsible for the other big upgrade quirk in this release, in which to upgrade a system which already installed those versions from the support repo, you need to either wait for those packages to make their way to the 11.1 branch of the support repo, or follow the steps in the aforementioned upgrade walkthrough to let the package system know it's okay to temporarily downgrade those. Developer Stack While Solaris 11.0 included Python 2.7, many of the bundled python modules weren’t packaged for it yet, limiting its usability. For 11.1, many more of the python modules include 2.7 versions (enough that I filtered them out of the below table, but you can always search on the package repository server for them. For other language runtimes and development tools, 11.1 expands the use of IPS mediated links to choose which version of a package is the default when the packages are designed to allow multiple versions to install side by side. For instance, in Solaris 11.0, GNU automake 1.9 and 1.10 were provided, and developers had to run them as either automake-1.9 or automake-1.10. In Solaris 11.1, when automake 1.11 was added, also added was a /usr/bin/automake mediated link, which points to the automake-1.11 program by default, but can be changed to another version by running the pkg set-mediator command. Mediated links were also used for the Java runtime & development kits in 11.1, changing the default versions to the Java 7 releases (the 1.7.0.x package versions), while allowing admins to switch links such as /usr/bin/javac back to Java 6 if they need to for their site, to deal with Java 7 compatibility or other issues, without having to update each usage to use the full versioned /usr/jdk/jdk1.6.0_35/bin/javac paths for every invocation. Desktop Stack As I mentioned before, we upgraded from X11R7.6 to X11R7.7, since a pleasant coincidence made the X.Org release dates line up nicely with our feature & code freeze dates for this release. (Or perhaps it wasn’t so coincidental, after all, one of the benefits of being the person making the release is being able to decide what schedule is most convenient for you, and this one worked well for me.) For the table below, I’ve skipped listing the packages in which we use the X11 “katamari” version for the Solaris package version (mainly packages combining elements of multiple upstream modules with independent version numbers), since they just all changed from 7.6 to 7.7. In the graphics drivers, we worked with Intel to update the Intel Integrated Graphics Processor support to support 3D graphics and kernel mode setting on the Ivy Bridge chipsets, and updated Nvidia’s non-FOSS graphics driver from 280.13 to 295.20. Higher up in the desktop stack, PulseAudio was added for audio support, and liblouis for Braille support, and the GNOME applications were built to use them. The Mozilla applications, Firefox & Thunderbird moved to the current Extended Support Release (ESR) versions, 10.x for each, to bring up-to-date security fixes without having to be on Mozilla’s agressive 6 week feature cycle release train. Detailed list of changes This table shows most of the changes to the FOSS packages between Solaris 11.0 and 11.1. As noted above, some were excluded for clarity, or to reduce noise and duplication. All the FOSS packages which didn't change the version number in their packaging info are not included, even if they had updates to fix bugs, security holes, or add support for new hardware or new features of Solaris.

BizTalk Server 2009 - Architecture Options

- by StuartBrierley

I recently needed to put forward a proposal for a BizTalk 2009 implementation and as a part of this needed to describe some of the basic architecture options available for consideration. While I already had an idea of the type of environment that I would be looking to recommend, I felt that presenting a range of options while trying to explain some of the strengths and weaknesses of those options was a good place to start. These outline architecture options should be equally valid for any version of BizTalk Server from 2004, through 2006 and R2, up to 2009. The following diagram shows a crude representation of the common implementation options to consider when designing a BizTalk environment. Each of these options provides differing levels of resilience in the case of failure or disaster, with the later options also providing more scope for performance tuning and scalability. Some of the options presented above make use of clustering. Clustering may best be described as a technology that automatically allows one physical server to take over the tasks and responsibilities of another physical server that has failed. Given that all computer hardware and software will eventually fail, the goal of clustering is to ensure that mission-critical applications will have little or no downtime when such a failure occurs. Clustering can also be configured to provide load balancing, which should generally lead to performance gains and increased capacity and throughput. (A) Single Servers This option is the most basic BizTalk implementation that should be considered. It involves the deployment of a single BizTalk server in conjunction with a single SQL server. This configuration does not provide for any resilience in the case of the failure of either server. It is however the cheapest and easiest to implement option of those available. Using a single BizTalk server does not provide for the level of performance tuning that is otherwise available when using more than one BizTalk server in a cluster. The common edition of BizTalk used in single server implementations is the standard edition. It should be noted however that if future demand requires increased capacity for a solution, this BizTalk edition is limited to scaling up the implementation and not scaling out the number of servers in use. Any need to scale out the solution would require an upgrade to the enterprise edition of BizTalk. (B) Single BizTalk Server with Clustered SQL Servers This option uses a single BizTalk server with a cluster of SQL servers. By utilising clustered SQL servers we can ensure that there is some resilience to the implementation in respect of the databases that BizTalk relies on to operate. The clustering of two SQL servers is possible with the standard edition but to go beyond this would require the enterprise level edition. While this option offers improved resilience over option (A) it does still present a potential single point of failure at the BizTalk server. Using a single BizTalk server does not provide for the level of performance tuning that is otherwise available when using more than one BizTalk server in a cluster. The common edition of BizTalk used in single server implementations is the standard edition. It should be noted however that if future demand requires increased capacity for a solution, this BizTalk edition is limited to scaling up the implementation and not scaling out the number of servers in use. You are also unable to take advantage of multiple message boxes, which would allow us to balance the SQL load in the event of any bottlenecks in this area of the implementation. Any need to scale out the solution would require an upgrade to the enterprise edition of BizTalk. (C) Clustered BizTalk Servers with Clustered SQL Servers This option makes use of a cluster of BizTalk servers with a cluster of SQL servers to offer high availability and resilience in the case of failure of either of the server types involved. Clustering of BizTalk is only available with the enterprise edition of the product. Clustering of two SQL servers is possible with the standard edition but to go beyond this would require the enterprise level edition. The use of a BizTalk cluster also provides for the ability to balance load across the servers and gives more scope for performance tuning any implemented solutions. It is also possible to add more BizTalk servers to an existing cluster, giving scope for scaling out the solution as future demand requires. This might be seen as the middle cost option, providing a good level of protection in the case of failure, a decent level of future proofing, but at a higher cost than the single BizTalk server implementations. (D) Clustered BizTalk Servers with Clustered SQL Servers – with disaster recovery/service continuity This option is similar to that offered by (C) and makes use of a cluster of BizTalk servers with a cluster of SQL servers to offer high availability and resilience in case of failure of either of the server types involved. Clustering of BizTalk is only available with the enterprise edition of the product. Clustering of two SQL servers is possible with the standard edition but to go beyond this would require the enterprise level edition. As with (C) the use of a BizTalk cluster also provides for the ability to balance load across the servers and gives more scope for performance tuning the implemented solution. It is also possible to add more BizTalk servers to an existing cluster, giving scope for scaling the solution out as future demand requires. In this scenario however, we would be including some form of disaster recovery or service continuity. An example of this would be making use of multiple sites, with the BizTalk server cluster operating across sites to offer resilience in case of the loss of one or more sites. In this scenario there are options available for the SQL implementation depending on the network implementation; making use of either one cluster per site or a single SQL cluster across the network. A multi-site SQL implementation would require some form of data replication across the sites involved. This is obviously an expensive and complex option, but does provide an extraordinary amount of protection in the case of failure.

The Interaction between Three-Tier Client/Server Model and Three-Tier Application Architecture Model

The three-tier client/server model is a network architectural approach currently used in modern networking. This approach divides a network in to three distinct components. Three-Tier Client/Server Model Components Client Component Server Component Database Component The Client Component of the network typically represents any device on the network. A basic example of this would be computer or another network/web enabled devices that are connected to a network. Network clients request resources on the network, and are usually equipped with a user interface for the presentation of the data returned from the Server Component. This process is done through the use of various software clients, and example of this can be seen through the use of a web browser client. The web browser request information from the Server Component located on the network and then renders the results for the user to process. The Server Components of the network return data based on specific client request back to the requesting client. Server Components also inherit the attributes of a Client Component in that they are a device on the network and that they can also request information from other Server Components. However what differentiates a Client Component from a Server Component is that a Server Component response to requests from devices on the network. An example of a Server Component can be seen in a web server. A web server listens for new requests and then interprets the request, processes the web pages, and then returns the processed data back to the web browser client so that it may render the data for the user to interpret. The Database Component of the network returns unprocessed data from databases or other resources. This component also inherits attributes from the Server Component in that it is a device on a network, it can request information from other server components and database components, and it also listens for new requests so that it can return data when needed. The three-tier client/server model is very similar to the three-tier application architecture model, and in fact the layers can be mapped to one another. Three-Tier Application Architecture Model Presentation Layer/Logic Business Layer/Logic Data Layer/Logic The Presentation Layer including its underlying logic is very similar to the Client Component of the three-tiered model. The Presentation Layer focuses on interpreting the data returned by the Business Layer as well as presents the data back to the user. Both the Presentation Layer and the Client Component focus primarily on the user and their experience. This allows for segments of the Business Layer to be distributable and interchangeable because the Presentation Layer is not directly integrated in with Business Layer. The Presentation Layer does not care where the data comes from as long as it is in the proper format. This allows for the Presentation Layer and Business Layer to be stored on one or more different servers so that it can provide a higher availability to clients requesting data. A good example of this is a web site that uses load balancing. When a web site decides to take on the task of load balancing they must obtain a network device that sits in front of a one or machines in order to distribute the request across multiple servers. When a user comes in through the load balanced device they are redirected to a specific server based on a few factors. Common Load Balancing Factors Current Server Availability Current Server Response Time Current Server Priority The Business Layer and corresponding logic are business rules applied to data prior to it being sent to the Presentation Layer. These rules are used to manipulate the data coming from the Data Access Layer, in addition to validating any data prior to being stored in the Data Access Layer. A good example of this would be when a user is trying to create multiple accounts under one email address. The Business Layer logic can prevent duplicate accounts by enforcing a unique email for every new account before the data is even stored in the Data Access Layer. The Server Component can be directly tied to this layer in that the server typically stores and process the Business Layer before it is returned to the end-user via the Presentation Layer. In addition the Server Component can also run automated process through the Business Layer on the data in the Data Access Layer so that additional business analysis can be derived from the data that has been already collected. The Data Layer and its logic are responsible for storing information so that it can be easily retrieved. Typical in most modern applications data is stored in a database management system however data can also be in the form of files stored on a file server. In addition a database can take on one of several forms. Common Database Formats XML File Pipe Delimited File Tab Delimited File Comma Delimited File (CSV) Plain Text File Microsoft Access Microsoft SQL Server MySql Oracle Sybase The Database component of the Networking model can be directly tied to the Data Layer because this is where the Data Layer obtains the data to return back the Business Layer. The Database Component basically allows for a place on the network to store data for future use. This enables applications to save data when they can and then quickly recall the saved data as needed so that the application does not have to worry about storing the data in memory. This prevents overhead that could be created when an application must retain all data in memory. As you can see the Three-Tier Client/Server Networking Model and the Three-Tiered Application Architecture Model rely very heavily on one another to function especially if different aspects of an application are distributed across an entire network. The use of various servers and database servers are wonderful when an application has a need to distribute work across the network. Network Components and Application Layers Interaction Database components will store all data needed for the Data Access Layer to manipulate and return to the Business Layer Server Component executes the Business Layer that manipulates data so that it can be returned to the Presentation Layer Client Component hosts the Presentation Layer that interprets the data and present it to the user

Seven Worlds will collide…. High Availability BI is not such a Distant Sun.

- by Testas

Over the last 5 years I have observed Microsoft persevere with the notion of Self Service BI over a series of conferences as far back as SQLBits V in Newport. The release of SQL Server 2012, improvements in Excel and the integration with SharePoint 2010 is making this a reality. Business users are now empowered to create their own BI reports through a number of different technologies such as PowerPivot, PowerView and Report Builder. This opens up a whole new way of working; improving staff productivity, promoting efficient decision making and delivering timely business reports. There is, however; a serious question to answer. What happens should any of these applications become unavailable? More to the point, how would the business react should key business users be unable to fulfil reporting requests for key management meetings when they require it? While the introduction of self-service BI will provide instant access to the creation of management information reports, it will also cause instant support calls should the access to the data become unavailable. These are questions that are often overlooked when a business evaluates the need for self-service BI. But as I have written in other blog posts, the thirst for information is unquenchable once the business users have access to the data. When they are unable to access the information, you will be the first to know about it and will be expected to have a resolution to the downtime as soon as possible. The world of self-service BI is pushing reporting and analytical databases to the tier 1 application level for some of Coeo’s customers. A level that is traditionally associated with mission critical OLTP environments. There is recognition that by making BI readily available to the business user, provisions also need to be made to ensure that the solution is highly available so that there is minimal disruption to the business. This is where High Availability BI infrastructures provide a solution. As there is a convergence of technologies to support a self-service BI culture, there is also a convergence of technologies that need to be understood in order to provide the high availability architecture required to support the self-service BI infrastructure. While you may not be the individual that implements these components, understanding the concepts behind these components will empower you to have meaningful discussions with the right people should you put this infrastructure in place. There are 7 worlds that you will have to understand to successfully implement a highly available BI infrastructure 1. Server/Virtualised server hardware/software 2. DNS 3. Network Load Balancing 4. Active Directory 5. Kerberos 6. SharePoint 7. SQL Server I have found myself over the last 6 months reaching out to knowledge that I learnt years ago when I studied for the Windows 2000 and 2003 (MCSE) Microsoft Certified System Engineer. (To the point that I am resuming my studies for the Windows Server 2008 equivalent to be up to date with newer technologies) This knowledge has proved very useful in the numerous engagements I have undertaken since being at Coeo, particularly when dealing with High Availability Infrastructures. As a result of running my session at SQLBits X and SQL Saturday in Dublin, the feedback I have received has been that many individuals desire to understand more of the concepts behind the first 6 “worlds” in the list above. Over the coming weeks, a series of blog posts will be put on this site to help understand the key concepts of each area as it pertains to a High Availability BI Infrastructure. Each post will not provide exhaustive coverage of the topic. For example DNS can be a book in its own right when you consider that there are so many different configuration options with Forward Lookup, Reverse Lookups, AD Integrated Zones and DNA forwarders to name some examples. What I want to do is share the pertinent points as it pertains to the BI infrastructure that you build so that you are equipped with the knowledge to have the right discussion when planning this infrastructure. Next, we will focus on the server infrastructure that will be required to support the High Availability BI Infrastructure, from both a physical box and virtualised perspective. Thanks Chris

SQL – Quick Start with Explorer Sections of NuoDB – Query NuoDB Database

- by Pinal Dave

This is the third post in the series of the blog posts I am writing about NuoDB. NuoDB is very innovative and easy-to-use product. I can clearly see how one can scale-out NuoDB with so much ease and confidence. In my very first blog post we discussed how we can install NuoDB (link), and in my second post I discussed how we can manage the NuoDB database transaction engines and storage managers with a few clicks (link). Note: You can Download NuoDB from here. In this post, we will learn how we can use the Explorer feature of NuoDB to do various SQL operations. NuoDB has a browser-based Explorer, which is very powerful and has many of the features any IDE would normally have. Let us see how it works in the following step-by-step tutorial. Let us go to the NuoDBNuoDB Console by typing the following URL in your browser: http://localhost:8080/ It will bring you to the QuickStart screen. Make sure that you have created the sample database. If you have not created sample database, click on Create Database and create it successfully. Now go to the NuoDB Explorer by clicking on the main tab, and it will ask you for your domain username and password. Enter the username as a domain and password as a bird. Alternatively you can also enter username as a quickstart and password as a quickstart. Once you enter the password you will be able to see the databases. In our example we have installed the Sample Database hence you will see the Test database in our Database Hierarchy screen. When you click on database it will ask for the database login. Note that Database Login is different from Domain login and you will have to enter your database login over here. In our case the database username is dba and password is goalie. Once you enter a valid username and password it will display your database. Further expand your database and you will notice various objects in your database. Once you explore various objects, select any database and click on Open. When you click on execute, it will display the SQL script to select the data from the table. The autogenerated script displays entire result set from the database. The NuoDB Explorer is very powerful and makes the life of developers very easy. If you click on List SQL Statements it will list all the available SQL statements right away in Query Editor. You can see the popup window in following image. Here is the cool thing for geeks. You can even click on Query Plan and it will display the text based query plan as well. In case of a SELECT, the query plan will be much simpler, however, when we write complex queries it will be very interesting. We can use the query plan tab for performance tuning of the database. Here is another feature, when we click on List Tables in NuoDB Explorer. It lists all the available tables in the query editor. This is very helpful when we are writing a long complex query. Here is a relatively complex example I have built using Inner Join syntax. Right below I have displayed the Query Plan. The query plan displays all the little details related to the query. Well, we just wrote multi-table query and executed it against the NuoDB database. You can use the NuoDB Admin section and do various analyses of the query and its performance. NuoDB is a distributed database built on a patented emergent architecture with full support for SQL and ACID guarantees. It allows you to add Transaction Engine processes to a running system to improve the performance of your system. You can also add a second Storage Engine to your running system for redundancy purposes. Conversely, you can shut down processes when you don’t need the extra database resources. NuoDB also provides developers and administrators with a single intuitive interface for centrally monitoring deployments. If you have read my blog posts and have not tried out NuoDB, I strongly suggest that you download it today and catch up with the learnings with me. Trust me though the product is very powerful, it is extremely easy to learn and use.

A Rose by Any Other Name..

- by Geoff N. Hiten

It is always a good start when you can steal a title line from one of the best writers in the English language. Let’s hope I can make the rest of this post live up to the opening. One recurring problem with SQL server is moving databases to new servers. Client applications use a variety of ways to resolve SQL Server names, some of which are not changed easily <cough SharePoint /cough>. If you happen to be using default instances on both the source and target SQL Server, then the solution is pretty simple. You create (or bug the network admin until she creates) two DNS “A” records. One points the old name to the new IP address. The other creates a new alias for the old server, since the original system name is now redirected. Note this will redirect ALL traffic from the old server to the new server, including RDP and file share connection attempts. Figure 1 – Microsoft DNS MMC Snap-In Figure 2 – DNS New Host Dialog Box Both records are necessary so you can still access the old server via an alternate name. Server Role IP Address Name Alias Source 10.97.230.60 SQL01 SQL01_Old Target 10.97.230.80 SQL02 SQL01 Table 1 – Alias List If you or somebody set up connections via IP address, you deserve to have to go to each app and fix it by hand. That is the only way to fix that particular foul-up. If have to deal with Named Instances either as a source or a target, then it gets more complicated. The standard fix is to use the SQL Server Configuration Manager (or one of its earlier incarnations) to create a SQL client alias to redirect the connection. This can be a pain installing and configuring the app on multiple client servers. The good news is that SQL Server Configuration Manager AND all of its earlier versions simply write a few registry keys. Extracting the keys into a .reg file makes centralized automated deployment a snap. If the client is a 32-bit system, you have to extract the native key. If it is a 64-bit, you have to extract the native key and the WoW (32 bit on 64 bit host) key. First, pick a development system to create the actual registry key. If you do this repeatedly, you can simply edit an existing registry file. Create the entry using the SQL Configuration Manager. You must use a 64-bit system to create the WoW key. The following example redirects from a named instance “SQL01\SQLUtiluty” to a default instance on “SQL02”. Figure 3 – SQL Server Configuration Manager - Native Figure 3 shows the native key listing. Figure 4 – SQL Server Configuration Manager – WoW If you think you don’t need the WoW key because your app is 64 it, think again. SQL Server Management Server is a 32-bit app, as are most SQL test utilities. Always create both keys for 64-bit target systems. Now that the keys exist, we can extract them into a .reg file. Fire up REGEDIT and browse to the following location: HKLM\Software\Microsoft\MSSQLServer\Client\ConnectTo. You can also search the registry for the string value of one of the server names (old or new). Right click on the “ConnectTo” label and choose “Export”. Save with an appropriate name and location. The resulting file should look something like this: Figure 5 – SQL01_Alias.reg Repeat the process with the location: HKLM\Software\Wow6432Node\Microsoft\MSSQLServer\Client\ConnectTo Note that if you have multiple alias entries, ALL of the entries will be exported. In that case, you can edit the file and remove the extra aliases. You can edit the files together into a single file. Just leave a blank line between new keys like this: Figure 6 – SQL01_Alias_All.reg Of course if you have an automatic way to deploy, it makes sense to have an automatic way to Un-deploy. To delete a registry key, simply edit the .reg file and replace the target with a “-“ sign like so. Figure 7 – SQL01_Alias_UNDO.reg Now we have the ability to move any database to any server without having to install or change any applications on any client server. The whole process should be transparent to the applications, which makes planning and coordinating database moves a far simpler task.

Getting WCF Bindings and Behaviors from any config source

- by cibrax

The need of loading WCF bindings or behaviors from different sources such as files in a disk or databases is a common requirement when dealing with configuration either on the client side or the service side. The traditional way to accomplish this in WCF is loading everything from the standard configuration section (serviceModel section) or creating all the bindings and behaviors by hand in code. However, there is a solution in the middle that becomes handy when more flexibility is needed. This solution involves getting the configuration from any place, and use that configuration to automatically configure any existing binding or behavior instance created with code. In order to configure a binding instance (System.ServiceModel.Channels.Binding) that you later inject in any endpoint on the client channel or the service host, you first need to get a binding configuration section from any configuration file (you can generate a temp file on the fly if you are using any other source for storing the configuration). private BindingsSection GetBindingsSection(string path) { System.Configuration.Configuration config = System.Configuration.ConfigurationManager.OpenMappedExeConfiguration( new System.Configuration.ExeConfigurationFileMap() { ExeConfigFilename = path }, System.Configuration.ConfigurationUserLevel.None); var serviceModel = ServiceModelSectionGroup.GetSectionGroup(config); return serviceModel.Bindings; } The BindingsSection contains a list of all the configured bindings in the serviceModel configuration section, so you can iterate through all the configured binding that get the one you need (You don’t need to have a complete serviceModel section, a section with the bindings only works). public Binding ResolveBinding(string name) { BindingsSection section = GetBindingsSection(path); foreach (var bindingCollection in section.BindingCollections) { if (bindingCollection.ConfiguredBindings.Count > 0 && bindingCollection.ConfiguredBindings[0].Name == name) { var bindingElement = bindingCollection.ConfiguredBindings[0]; var binding = (Binding)Activator.CreateInstance(bindingCollection.BindingType); binding.Name = bindingElement.Name; bindingElement.ApplyConfiguration(binding); return binding; } } return null; } The code above does just that, and also instantiates and configures the Binding object (System.ServiceModel.Channels.Binding) you are looking for. As you can see, the binding configuration element contains a method “ApplyConfiguration” that receives the binding instance that needs to be configured. A similar thing can be done for instance with the “Endpoint” behaviors. You first get the BehaviorsSection, and then, the behavior you want to use. private BehaviorsSection GetBehaviorsSection(string path) { System.Configuration.Configuration config = System.Configuration.ConfigurationManager.OpenMappedExeConfiguration( new System.Configuration.ExeConfigurationFileMap() { ExeConfigFilename = path }, System.Configuration.ConfigurationUserLevel.None); var serviceModel = ServiceModelSectionGroup.GetSectionGroup(config); return serviceModel.Behaviors; }public List<IEndpointBehavior> ResolveEndpointBehavior(string name) { BehaviorsSection section = GetBehaviorsSection(path); List<IEndpointBehavior> endpointBehaviors = new List<IEndpointBehavior>(); if (section.EndpointBehaviors.Count > 0 && section.EndpointBehaviors[0].Name == name) { var behaviorCollectionElement = section.EndpointBehaviors[0]; foreach (BehaviorExtensionElement behaviorExtension in behaviorCollectionElement) { object extension = behaviorExtension.GetType().InvokeMember("CreateBehavior", BindingFlags.InvokeMethod | BindingFlags.NonPublic | BindingFlags.Instance, null, behaviorExtension, null); endpointBehaviors.Add((IEndpointBehavior)extension); } return endpointBehaviors; } return null; } In this case, the code for creating the behavior instance is more tricky. First of all, a behavior in the configuration section actually represents a set of “IEndpoint” behaviors, and the behavior element you get from the configuration does not have any public method to configure an existing behavior instance. This last one only contains a protected method “CreateBehavior” that you can use for that purpose. Once you get this code implemented, a client channel can be easily configured as follows var binding = resolver.ResolveBinding("MyBinding"); var behaviors = resolver.ResolveEndpointBehavior("MyBehavior"); SampleServiceClient client = new SampleServiceClient(binding, new EndpointAddress(new Uri("http://localhost:13749/SampleService.svc"), new DnsEndpointIdentity("localhost"))); foreach (var behavior in behaviors) { if(client.Endpoint.Behaviors.Contains(behavior.GetType())) { client.Endpoint.Behaviors.Remove(behavior.GetType()); } client.Endpoint.Behaviors.Add(behavior); } The code above assumes that a configuration file (in any place) with a binding “MyBinding” and a behavior “MyBehavior” exists. That file can look like this, <system.serviceModel> <bindings> <basicHttpBinding> <binding name="MyBinding"> <security mode="Transport"></security> </binding> </basicHttpBinding> </bindings> <behaviors> <endpointBehaviors> <behavior name="MyBehavior"> <clientCredentials> <windows/> </clientCredentials> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> The same thing can be done of course in the service host if you want to manually configure the bindings and behaviors.

Big Data – Role of Cloud Computing in Big Data – Day 11 of 21

- by Pinal Dave

In yesterday’s blog post we learned the importance of the NewSQL. In this article we will understand the role of Cloud in Big Data Story What is Cloud? Cloud is the biggest buzzword around from last few years. Everyone knows about the Cloud and it is extremely well defined online. In this article we will discuss cloud in the context of the Big Data. Cloud computing is a method of providing a shared computing resources to the application which requires dynamic resources. These resources include applications, computing, storage, networking, development and various deployment platforms. The fundamentals of the cloud computing are that it shares pretty much share all the resources and deliver to end users as a service. Examples of the Cloud Computing and Big Data are Google and Amazon.com. Both have fantastic Big Data offering with the help of the cloud. We will discuss this later in this blog post. There are two different Cloud Deployment Models: 1) The Public Cloud and 2) The Private Cloud Public Cloud Public Cloud is the cloud infrastructure build by commercial providers (Amazon, Rackspace etc.) creates a highly scalable data center that hides the complex infrastructure from the consumer and provides various services. Private Cloud Private Cloud is the cloud infrastructure build by a single organization where they are managing highly scalable data center internally. Here is the quick comparison between Public Cloud and Private Cloud from Wikipedia: Public Cloud Private Cloud Initial cost Typically zero Typically high Running cost Unpredictable Unpredictable Customization Impossible Possible Privacy No (Host has access to the data Yes Single sign-on Impossible Possible Scaling up Easy while within defined limits Laborious but no limits Hybrid Cloud Hybrid Cloud is the cloud infrastructure build with the composition of two or more clouds like public and private cloud. Hybrid cloud gives best of the both the world as it combines multiple cloud deployment models together. Cloud and Big Data – Common Characteristics There are many characteristics of the Cloud Architecture and Cloud Computing which are also essentially important for Big Data as well. They highly overlap and at many places it just makes sense to use the power of both the architecture and build a highly scalable framework. Here is the list of all the characteristics of cloud computing important in Big Data Scalability Elasticity Ad-hoc Resource Pooling Low Cost to Setup Infastructure Pay on Use or Pay as you Go Highly Available Leading Big Data Cloud Providers There are many players in Big Data Cloud but we will list a few of the known players in this list. Amazon Amazon is arguably the most popular Infrastructure as a Service (IaaS) provider. The history of how Amazon started in this business is very interesting. They started out with a massive infrastructure to support their own business. Gradually they figured out that their own resources are underutilized most of the time. They decided to get the maximum out of the resources they have and hence they launched their Amazon Elastic Compute Cloud (Amazon EC2) service in 2006. Their products have evolved a lot recently and now it is one of their primary business besides their retail selling. Amazon also offers Big Data services understand Amazon Web Services. Here is the list of the included services: Amazon Elastic MapReduce – It processes very high volumes of data Amazon DynammoDB – It is fully managed NoSQL (Not Only SQL) database service Amazon Simple Storage Services (S3) – A web-scale service designed to store and accommodate any amount of data Amazon High Performance Computing – It provides low-tenancy tuned high performance computing cluster Amazon RedShift – It is petabyte scale data warehousing service Google Though Google is known for Search Engine, we all know that it is much more than that. Google Compute Engine – It offers secure, flexible computing from energy efficient data centers Google Big Query – It allows SQL-like queries to run against large datasets Google Prediction API – It is a cloud based machine learning tool Other Players Besides Amazon and Google we also have other players in the Big Data market as well. Microsoft is also attempting Big Data with the Cloud with Microsoft Azure. Additionally Rackspace and NASA together have initiated OpenStack. The goal of Openstack is to provide a massively scaled, multitenant cloud that can run on any hardware. Thing to Watch The cloud based solutions provides a great integration with the Big Data’s story as well it is very economical to implement as well. However, there are few things one should be very careful when deploying Big Data on cloud solutions. Here is a list of a few things to watch: Data Integrity Initial Cost Recurring Cost Performance Data Access Security Location Compliance Every company have different approaches to Big Data and have different rules and regulations. Based on various factors, one can implement their own custom Big Data solution on a cloud. Tomorrow In tomorrow’s blog post we will discuss about various Operational Databases supporting Big Data.
