Does Extension matter for Creating a database?
We have 3 types of file extensions in SQL Server. MDF, NDF and LDF each one representing Primary, Secondary and Log file respectively. Do you think these extensions are need to be given to the respective files? If your answer is yes then you are wrong. You can give any extension as you like or else you can even interchange these 3 extensions to primary, secondary and log file. Extension plays a important role for us to understand which file is what where as when you attach the db, SQL (by pointing the primary file) knows where the log file and the additional files for the db, it will attach the database without any errors. This is because SQL will check the primary file (which you have pointed) and if it’s in right format then it will start reading the header page to fetch additional details about other files and attach the database.
SQL Server 2008 R2 New Features
On April 22nd 2010 SQL Server 2008 R2 is released to production. I tried to get the list of new features added to R2 however I couldn’t find all the new features in a single thread so I’m writing this article to populate the list of new features added to SQL Server 2008 R2. There are many new features added to DBA and BI however I feel we have more features for BI.
Performance Data Collector – Part 2
Last month I’ve wrote an article on Performance Data Collector part one, I thought of writing part 2 soon however I was stuck with Organizing SQL Code Camp with my fellow MVP Deepak & Sugesh. Now it’s almost a month so thought of writing the second part. In this part we are going to see how to customize the data collection, retrieval of reports from PDW (Performance Data Warehouse) etc.
SQL Code Camp at Chennai–Great Success
I, Deepak & Sugesh have organized SQL Code Camp – One full day event for SQL Server last Saturday (17th July 2010). We are happy to say that this is the first one full day event for SQL Server held in India and we are proud that we are organizing it. Deepak and Sugesh has already created a post so I’m not going to write much about the event. You can find our experiences and learning from the link below.
Performance Data Collector – Part 1
Performance Data Collector is one of the new features that’s accompanied from SQL Server 2008. If you are a DBA , you know it’s very hard to get performance data from necessary inputs. We will get the data from Perfmon (system monitor), profiler, DMV etc and correlating this data is very hard, implementing the same process or scripts across your environment is also time consuming one. To Overcome this MS has added Performance data collector feature in SQL 2008. In a Nutshell performance data collector will collect performance data (integrating all your data from your server), upload it in centralized management data warehouse (MDW) in relational format and finally allows you to see reports in graphical format.
