  • Replication Presentation at the Southampton User Group

    - by GavinPayneUK
    Last night I delivered a presentation about SQL Server’s replication services to Mark Pryce-Maher’s user group in Southampton. As those who were there saw this is a massive topic and to deliver anything but a high level overview in 45 minutes does an injustice to the subject.  Therefore, what I gave the Wednesday night audience was a deliberately high level introduction through my slides with an accompanying detailed commentary as well as answering questions as we went along. The great thing...(read more)

  • Speaker Prep Tip: Use the AV Studio Built into that Laptop

    - by merrillaldrich
    Over at erinstellato.com there is a great post this week about tips for new presenters. Ms. Stellato suggests, insightfully, that we record ourselves, which is really a fantastic piece of advice. What’s extra-cool is that today you don’t need any special equipment or expensive software to do just that. This week I “filmed” two run-throughs of my talk for SQL Saturday tomorrow. For me, the timing is the hardest thing – figuring out how much content I can really present in the time allowed without...(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.

  • TechEd 2014 Day 3

    - by John Paul Cook
    There is some confusion about durability of data stored in SQL Server in-memory tables, so some review of the concepts is appropriate. The in-memory option is enabled at the database level. Enabling it at the database level only gives you the option to specify the in-memory feature on a table by table basis. No existing tables or new tables will by default become in-memory tables when you enable the feature at the database level. If you choose to make a table an in-memory table, by default it is...(read more)

  • 5 Reasons You Must Start Capturing Baseline Data

    It is widely acknowledged within the SQL Server community that baselines represent valuable information that DBAs should capture. Unfortunately, very few companies manage to log and report on this information, and DBAs are then forced to troubleshoot from the hip and scramble to find evidence to prove that the database is not the problem. This article will make a compelling argument for why DBAs must start capturing baseline information, and will create a roadmap for subsequent posts.

  • Geek City: What gets logged for index rebuild operations?

    - by Kalen Delaney
    This blog post was inspired by a question from a future student. Someone who was already booked for my SQL Server Internals class in June asked for some information on a current problem he was having with transaction log writes causing excessive wait times during index rebuild operations when run in ONLINE mode. He wanted to know if switching to BULK_LOGGED recovery could help. I knew the difference between ALTER INDEX in FULL vs BULK_LOGGED recovery when doing normal OFFLINE rebuilds, but I wasn't...(read more)

  • Queries barely over the Cost Threshold for Parallelism

    - by jchang
    I had discussed SQL Server parallelism in Oct 2010, with my thoughts on the best settings for: Cost Threshold for Parallelism (CTP) and Max Degrees of Parallelism (MAXDOP) in Parallelism Strategy and Comments . At the time, I had intended to follow up with detailed measurements. So now a mere 2 years later, here it is. The general thought was that CTP should be raised from the default value of 5, and MAXDOP should be changed from unrestricted, on modern systems with very many cores, and most especially...(read more)

  • Is Job Running?

    - by Derek D.
    The following SQL Server script works to determine if a particular job is currently running. This feature is nice to have if you do not want jobs to step over one another. I frequently will use this script as the first step of the job. If it is currently running, then the [...]

  • 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?

  • Stairway to Database Design STEP 2: Domains, Constraints and Defaults

    A clear understanding of SQL Data Types and domains is a fundamental requirement for the Database Developer, but it is not elementary. If you select the most appropriate data type, it can sidestep a variety of errors. Furthermore, if you then define the data domains as exactly as possible via constraints, you can catch a variety of those problems that would otherwise bedevil the work of the application programmer.
