  • Command line tool for MediaWiki?

    - by Magnus
    Is there a command line tool that would allow me to script creation of accounts on a MediaWiki instance? The UI for creating an account is painful, and very time consuming when tasked with creating 10+ accounts at a time. Unfortunately I can't get ImportUsers to work due to the very old version of MediaWiki we use (and upgrading is unfortunately not possible at this time).

  • dependency analysis from C# code thru to database tables/columns

    - by fpdave
    I'm looking for a tool to do system wide dependency analysis in C# code and SQL-Server databases. Its looking like the only tool available that does this might be CAST (cast software), which is expensive and it does lots more besides that I dont really need. c# code thru to database column dependency would be hugely useful for many reasons, including: - determining effects of database changes throughout the system - seeing hot spots in the database schema - finding dead stored procedures/tables/etc - understanding the existing code base does anyone know of any such tools?

  • July, the 31 Days of SQL Server DMO’s – Day 3 (sys.dm_exec_connections)

    - by Tamarick Hill
      The third DMV we will review is the sys.dm_exec_connections DMV. This DMV is Server-Scoped and displays information about each and every current connection on your SQL Server Instance. Lets take a look at some information that this DMV returns. SELECT * FROM sys.dm_exec_connections After reviewing this DMV, in my opinion, its not a whole lot of useful information returned from this DMV from a monitoring or troubleshooting standpoint. The primary use case I have for this DMV is when I need to get a quick count of how many connections I have on one of my SQL Server boxes. For this purpose a quick SELECT COUNT(*) satisfies my need. However, for those who need it, there is other information such as what type of authentication a specific connection is using, network packet size, and client/local TCP ports being used. This information can come in handy for specific scenarios but you probably wont need it very much for your day to day monitoring/troubleshooting needs. However, this is still an important DMV that you should be aware of in the event that you need it. For more information on this DMV, please see the below Books Online link: http://msdn.microsoft.com/en-us/library/ms181509.aspx

  • ASP.NET 4.0- CompressionEnabled Property in session state 4.0

    - by Jalpesh P. Vadgama
    Hello Guys, This blog has been quite for few days. Because i was busy with some personal and professional work both and that’s why i am not able to work on writing blog posts which i have discovered in last few days. Here is one features of asp.net 4.0 that I am going to explain. As a web developer we all know about session. Without the use of session any database driven web application is incomplete. As we all know unlike windows form web forms are state less so when user interacts with web application we need to maintain state amongst web pages and we are using session for maintaining state between web pages for each users. ASP.NET is also provide same kind of session state functionalities. ASP.Net Session state identify request coming for same user and same browser for specific session time out interval and its preserves values in session for that specific time intervals and that’s help us in maintaining state amongst web pages for a specific user. ASP.NET Session state allows us to store session in three way 1. IncProc 2. Session State Service 3. SQL Server. In SQL Server mode it will store session in SQL Server tables instead of storing it in Server Memory. ASP.NET 4.0 provides a new property called Compression Enabled that means when we store values in serialized form in SQL Server with GZip Compression and that results in better performance. For that you need to store property in web.config like following. <sessionState allowCustomSqlDatabase="true" sqlConnectionString="data source=Server;Initial Catalog=aspnetsessionstatedb" compressionEnabled="true" /> That’s it now with the use of this property you can have better performance when you are storing large amount of data in session.But still you need to decide that why you want to stored large amount of data in session because its against best practices.

  • Is there a Kerberos testing tool?

    - by ixe013
    I often use openssl s_client to test and debug SSL connections (to LDAPS or HTTPS services). It allows me to isolate the problem down to SSL, without anything getting in the way. I know about klist that allows me to purge the ticket cache. Is there tool that would allow me to ask a Kerberos ticket for a given server, not event sending it ? Just enough to see the whole Kerberos exchange in Wireshark for example ?

  • Performance monitor visualization tool

    - by MK
    I'm looking for a tool to display data from performance monitor counters. I'm looking for something that would be visually appealing (look like a dashboard) and it should be able to aggregate (sum up) over multiple counters. No thresholds/alarming needed, we are using Nagios for that.

  • Automating SQL Execution Plan analysis

    - by jchang
    Last year, I made my tool for automating execution plan analysis available on www.qdpma.com The original version could parse execution plans from sys.dm_exec_query_stats or dm_exec_cached_plans and generate a cross-reference of which execution plans employed each index. The DMV sys.dm_db_index_usage_stats shows how often each index is used, but not where, that is, which particular stored procedure or My latest version can now also 1) use the DMV sys.dm_exec_procedure_stats, 2) it can also get the...(read more)

  • SQL Azure Service Issues &ndash; 10.27.2012 (Restored Now)

    - by ToStringTheory
    Please note that if you have a Windows Azure website, or use SQL Azure, your site may be experiencing downtime currently.  Notice I just called in regarding one of my public facing internet sites, because the site was failing to load anything but its error page, I couldn’t connect to the database to inspect application error logs, and the Windows Azure Management portal won’t load the SQL Azure extension. After speaking to the representative, he also mentioned that they were also having some problems updating the Service Dashboard which shows service up/down time, and for now, they are posting messages at http://account.windowsazure.com.  Please note that this issue may only be effecting certain regions.  Last, I may have misheard the representative, but he said that the outage was being categorized as a level 8, and if I heard correctly, I think he said that level 8 was the worst level.  I can’t say for sure on this though, because the phone connection to their support number was bad – large amounts of white noise. Good Luck! Update It appears that this outage may also be effecting the following services: SQL Database, Service Bus, Datamarket, Windows Azure Marketplace, Shared Caching, Access Control 2.0, and SQL Reporting. The note on the account page says for the South Central US region, however, I believe the representative I spoke to also mentioned North Central. As I said before though, the connection was bad. Update 2 My site regained connectivity about an hour ago, and it appears that the service dashboard is back in operation with correct status and history. It does appear that I misheard on the phone regarding multiple regions, so chances are this only effected a percentage of the platform. All in all, if this WAS their worst level of a problem, they really got it fixed and back up pretty fast. All in all, I understand that it is inherent for a complex system such as Azure to have ups and downs, but at the end of the day, I am still happy to support Azure to its fullest!

  • Cluster Nodes as RAID Drives

    - by BuckWoody
    I'm unable to sleep tonight so I thought I would push this post out VERY early. When you don't sleep your mind takes interesting turns, which can be a good thing. I was watching a briefing today by a couple of friends as they were talking about various ways to arrange a Windows Server Cluster for SQL Server. I often see an "active" node of a cluster with a "passive" node backing it up. That means one node is working and accepting transactions, and the other is not doing any work but simply "standing by" waiting for the first to fail over. The configuration in the demonstration I saw was a bit different. In this example, there were three nodes that were actively working, and a fourth standing by for all three. I've put configurations like this one into place before, but as I was looking at their architecture diagram, it looked familar - it looked like a RAID drive setup! And that's not a bad way to think about your cluster arrangements. The same concerns you might think about for a particular RAID configuration provides a good way to think about protecting your systems in general. So even if you're not staying awake all night thinking about SQL Server clusters, take this post as an opportunity for "lateral thinking" - a way of combining in your mind the concepts from one piece of knowledge to another. You might find a new way of making your technical environment a little better. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Generic Repository with SQLite and SQL Compact Databases

    - by Andrew Petersen
    I am creating a project that has a mobile app (Xamarin.Android) using a SQLite database and a WPF application (Code First Entity Framework 5) using a SQL Compact database. This project will even eventually have a SQL Server database as well. Because of this I am trying to create a generic repository, so that I can pass in the correct context depending on which application is making the request. The issue I ran into is my DataContext for the SQL Compact database inherits from DbContext and the SQLite database inherits from SQLiteConnection. What is the best way to make this generic, so that it doesn't matter what kind of database is on the back end? This is what I have tried so far on the SQL Compact side: public interface IRepository<TEntity> { TEntity Add(TEntity entity); } public class Repository<TEntity, TContext> : IRepository<TEntity>, IDisposable where TEntity : class where TContext : DbContext { private readonly TContext _context; public Repository(DbContext dbContext) { _context = dbContext as TContext; } public virtual TEntity Add(TEntity entity) { return _context.Set<TEntity>().Add(entity); } } And on the SQLite side: public class ElverDatabase : SQLiteConnection { static readonly object Locker = new object(); public ElverDatabase(string path) : base(path) { CreateTable<Ticket>(); } public int Add<T>(T item) where T : IBusinessEntity { lock (Locker) { return Insert(item); } } }

  • Designing a Database Application with OOP

    - by Tim C
    I often develop SQL database applications using Linq, and my methodology is to build model classes to represent each table, and each table that needs inserting or updating gets a Save() method (which either does an InsertOnSubmit() or SubmitChanges(), depending on the state of the object). Often, when I need to represent a collection of records, I'll create a class that inherits from a List-like object of the atomic class. ex. public class CustomerCollection : CoreCollection<Customer> { } Recently, I was working on an application where end-users were experiencing slowness, where each of the objects needed to be saved to the database if they met a certain criteria. My Save() method was slow, presumably because I was making all kinds of round-trips to the server, and calling DataContext.SubmitChanges() after each atomic save. So, the code might have looked something like this foreach(Customer c in customerCollection) { if(c.ShouldSave()) { c.Save(); } } I worked through multiple strategies to optimize, but ultimately settled on passing a big string of data to a SQL stored procedure, where the string has all the data that represents the records I was working with - it might look something like this: CustomerID:34567;CurrentAddress:23 3rd St;CustomerID:23456;CurrentAddress:123 4th St So, SQL server parses the string, performs the logic to determine appropriateness of save, and then Inserts, Updates, or Ignores. With C#/Linq doing this work, it saved 5-10 records / s. When SQL does it, I get 100 records / s, so there is no denying the Stored Proc is more efficient; however, I hate the solution because it doesn't seem nearly as clean or safe. My real concern is that I don't have any better solutions that hold a candle to the performance of the stored proc solution. Am I doing something obviously wrong in how I'm thinking about designing database applications? Are there better ways of designing database applications?

  • Fun with upgrading and BCP

    - by DavidWimbush
    I just had trouble with using BCP out via xp_cmdshell. Probably serves me right but that's a different issue. I got a strange error message 'Unable to resolve column level collations' which turned out to be a bit misleading. I wasted some time comparing the collations of the the server, the database and all the columns in the query. I got so desperate that I even read the Books Online article. Still no joy but then I tried the interweb. It turns out that calling bcp without qualifying it with a path causes Windows to search the folders listed in the Path environment variable - in that order - and execute the first version of BCP it can find. But when you do an in-place version upgrade, the new paths are added on the end of the Path variable so you don't get the latest version of BCP by default. To check which version you're getting execute bcp -v at the command line. The version number will correspond to SQL Server version numbering (eg. 10.50.n = 2008 R2). To examine and/or edit the Path variable, right-click on My Computer, select Properties, go to the Advanced tab and click on the Environment Variables button. If you change the variable you'll have to restart the SQL Server service before it takes effect.

  • Tool to determine filesystem on removable media

    - by Todd Brooks
    I have a CompactFlash card that is used in a custom piece of hardware. WAV files are written to it. Windows doesn't recognize the media and wants to format it, which rules out FAT 16/32, NTFS, UDF, etc. Is there a Windows tool that can determine what filesystem the media is using and possible read the contents? I've tried dskprobe.exe, but it did not work.

  • SQL Server Interview Questions

    - by Rodney Vinyard
    User-Defined Functions Scalar User-Defined Function A Scalar user-defined function returns one of the scalar data types. Text, ntext, image and timestamp data types are not supported. These are the type of user-defined functions that most developers are used to in other programming languages. Table-Value User-Defined Function An Inline Table-Value user-defined function returns a table data type and is an exceptional alternative to a view as the user-defined function can pass parameters into a T-SQL select command and in essence provide us with a parameterized, non-updateable view of the underlying tables. Multi-statement Table-Value User-Defined Function A Multi-Statement Table-Value user-defined function returns a table and is also an exceptional alternative to a view as the function can support multiple T-SQL statements to build the final result where the view is limited to a single SELECT statement. Also, the ability to pass parameters into a T-SQL select command or a group of them gives us the capability to in essence create a parameterized, non-updateable view of the data in the underlying tables. Within the create function command you must define the table structure that is being returned. After creating this type of user-defined function, I can use it in the FROM clause of a T-SQL command unlike the behavior found when using a stored procedure which can also return record sets.

  • SQL Rally Pre-Con: Data Warehouse Modeling – Making the Right Choices

    - by Davide Mauri
    As you may have already learned from my old post or Adam’s or Kalen’s posts, there will be two SQL Rally in North Europe. In the Stockholm SQL Rally, with my friend Thomas Kejser, I’ll be delivering a pre-con on Data Warehouse Modeling: Data warehouses play a central role in any BI solution. It's the back end upon which everything in years to come will be created. For this reason, it must be rock solid and yet flexible at the same time. To develop such a data warehouse, you must have a clear idea of its architecture, a thorough understanding of the concepts of Measures and Dimensions, and a proven engineered way to build it so that quality and stability can go hand-in-hand with cost reduction and scalability. In this workshop, Thomas Kejser and Davide Mauri will share all the information they learned since they started working with data warehouses, giving you the guidance and tips you need to start your BI project in the best way possible?avoiding errors, making implementation effective and efficient, paving the way for a winning Agile approach, and helping you define how your team should work so that your BI solution will stand the test of time. You'll learn: Data warehouse architecture and justification Agile methodology Dimensional modeling, including Kimball vs. Inmon, SCD1/SCD2/SCD3, Junk and Degenerate Dimensions, and Huge Dimensions Best practices, naming conventions, and lessons learned Loading the data warehouse, including loading Dimensions, loading Facts (Full Load, Incremental Load, Partitioned Load) Data warehouses and Big Data (Hadoop) Unit testing Tracking historical changes and managing large sizes With all the Self-Service BI hype, Data Warehouse is become more and more central every day, since if everyone will be able to analyze data using self-service tools, it’s better for him/her to rely on correct, uniform and coherent data. Already 50 people registered from the workshop and seats are limited so don’t miss this unique opportunity to attend to this workshop that is really a unique combination of years and years of experience! http://www.sqlpass.org/sqlrally/2013/nordic/Agenda/PreconferenceSeminars.aspx See you there!
