8 Things To Do After You Install SQL Server

  3. 3. Overview SQL Server’s Default Installation Rules are BAD!!! Let’s Fix It!!
  4. 4. Set Max Memory • The default setting for max server memory is 2147483647 MB (2.1 Petabytes!!!) • If this setting is not changed SQL Server will attempt to grab all of the memory on the box • This can lead to paging of the Windows O/S • Best Practice is to allocate 80% of memory to SQL Server • The one exception is very large memory servers— Windows generally needs about 6-8 GB to run comfortably • Minimum Memory doesn’t need to be set except on VMs
  5. 5. Configure MaxDOP  Default setting is 0 which uses all available processors in parallel query execution  This can lead to CXPACKET and Scheduler waits  Best Practice  For servers > 8 CPUs = MAXDOP=8  For servers < 8 CPUs = MAXDOP 0 to n  Sharepoint MAXDOP=1
  6. 6. Change Model File Sizes  Initial Size and Autogrowth are way too small initially  There is no right number— base on roughly how big your databases will be  Definitely, change autogrowth to remove percentage growth and go with fixed value  Goal is to avoid file system fragementation
  7. 7. Change Model Recovery Model • By default—Model is in full recovery mode • Typically I set to simple—if a database needs to be in full recovery mode, set it manually
  8. 8. Add Files to TempDB  If the number of logical processors < 8 then number of TempDB Files = number of CPUs  If logical processors > 8, then number of TempDB Files = 8  If contention continues add files in multiples of 4  All TempDB files should be the same size and have same autogrowth settings
  9. 9. Create SQL Agent Alerts for Critical Errors • Ensures you get notified when something bad happens on your server • Know that problems are happening before your users do • Can tie alerts to actions and/or pages
  10. 10. Patch SQL Server  Find out the current Service Pack and Cumulative Update level (sqlserverbuilds.blogspot.com)  Patch your server—no time like install time
  11. 11. Script your Installs • Don’t use the GUI • Automate for consistency, and speed • You should still QA—this process is dependent on things like having standard disk letters • Download at my blog
  12. 12. Summary  Do this stuff  Automate and Repeat  Your Servers will love you Slides joedantoni.wordpress.com Twitter @jdanton Email jdanton1@yahoo.com
