  • Bringing Alerts and Operators together with Notifications

    - by fatherjack
    I have covered SQL Server Alerts (Alerts are good, arent they?) on this blog before and I more recently did a post regarding Notifications (Are your Jobs talking to you) and how they should be configured. Now we need to check that these things are linked up so that when an Alert condition is met that you get the appropriate Notifications sent to Operators. Straight into the code we need and then a review of what it does ... DECLARE @ChosenOperator SYSNAME DECLARE @FailSafeOp TABLE ...(read more)

  • SSIS Basics: Using the Merge Join Transformation

    SSIS is able to take sorted data from more than one OLE DB data source and merge them into one table which can then be sent to an OLE DB destination. This 'Merge Join' transformation works in a similar way to a SQL join by specifying a 'join key' relationship. this transformation can save a great deal of processing on the destination. Annette Allen, as usual, gives clear guidance on how to do it.

  • No Significant Fragmentation? Look Closer…

    If you are relying on using 'best-practice' percentage-based thresholds when you are creating an index maintenance plan for a SQL Server that checks the fragmentation in your pages, you may miss occasional 'edge' conditions on larger tables that will cause severe degradation in performance. It is worth being aware of patterns of data access in particular tables when judging the best threshold figure to use.

  • Designing Databases for Rapid Resilience

    As the volume of data increases, DBAs need to plan more actively for rapid restores in the event of failure. For this, the intelligent use of filegroups is important, particularly when the Enterprise Edition of SQL Server offers the hope of online restores. How, though, should you arrange your data on the different filegroups? What happenens if the primary filegroup gets corrupted? Why backup and restore indexes?

  • What a .NET developer should know or practice (know how to do)? [closed]

    - by Olav
    I would like to have a list of basic tasks that .NET developers of different flavors using Visual Studio/SQL Server should be able to do. Ideally with a kind of lab environment where I could practice. VB.NET or C#, latest versions of ASP.NET, WPF and Silverlight. I am looking for small practical "atomic" tasks (like adding a db connection for example) I am looking for some existing labs/lists rather than specific points in the answers. (But I would not mind collaborating in developing material).

  • Collecting the Information in the Default Trace

    The default trace is still the best way of getting important information to provide a security audit of SQL Server, since it records such information as logins, changes to users and roles, changes in object permissions, error events and changes to both database settings and schemas. The only trouble is that the information is volatile. Feodor shows how to squirrel the information away to provide reports, check for unauthorised changes and provide forensic evidence.

  • Help with MVC design pattern?

    - by user3681240
    I am trying to build a java program for user login but I am not sure if my MVC design is accurate.

  • Implenting ActiveRecord with inheritance?

    - by King
    I recently converted an old application that was using XML files as the data store to use SQL instead. To avoid a lot of changes I basically created ActiveRecord style classes that inherited from the original business objects. For example SomeClassRecord :SomeClass //ID Property //Save method I then used this new class in place of the other one, because of polymorphism I didn't need to change any methods that took SomeClass as a parameter. Would this be considered 'Bad'? What would be a better alternative?

  • Windows Azure from a Data Perspective

    Before creating a data application in Windows Azure, it is important to make choices based on the type of data you have, as well as the security and the business requirements. There are a wide range of options, because Windows Azure has intrinsic data storage, completely separate from SQL Azure, that is highly available and replicated. Your data requirements are likely to dictate the type of data storage options you choose.

  • Farm is unavailable exception

    - by H(at)Ni
    I was faced today by an exception saying that "Farm is unavailable" and the call stack which for sure wasn't useful for diagnosing that type of error. My solution to this error was straight forward and below are the steps that I've followed: 1. Open run and type services.msc 2. Search for the SQL server instance and in my case I've found that it's not running, so simply start it :) After that, refresh the page and everything is normal again !

  • A quick look at: sys.dm_os_buffer_descriptors

    - by fatherjack
    SQL Server places data into cache as it reads it from disk so as to speed up future queries. This dmv lets you see how much data is cached at any given time and knowing how this changes over time can help you ensure your servers run smoothly and are adequately resourced to run your systems. This dmv gives the number of cached pages in the buffer pool along with the database id that they relate to: USE [tempdb] GO SELECT COUNT(*) AS cached_pages_count , CASE database_id ...(read more)
