DBA Best Practices for Database Settings

If you are going to play with database settings then wait and read following base lines as best practices

  1. Unless you know exactly what you are doing and have already performed impartial experiments that prove that making SQL Server configuration changes helps you in your particular environment, do not change any of the SQL Server configuration settings.
  2. In almost all cases, leave the “auto create statistics” and “auto update statistics” options on for all user databases.
  3. In most cases, the settings for the “maximum server memory” and the “minimum server memory” should be left to their default values. This is because the default values allow SQL Server to dynamically allocate memory in the server for the best overall optimum performance. If you use AWE memory, then this recommendation is to be ignored, and maximum memory needs to be set manually.
  4. Many databases need to be shrunk periodically in order to free up disk space as older data is deleted from the database. But don’t be tempted to use the “auto shrink” database option, as it can waste SQL Server resources unnecessarily. Instead, shrink databases manually.
  5. Don’t rely on AUTOGROWTH to automatically manage the size of your databases. Instead, proactively monitor and alter database size as circumstances dictate. Only use AUTOGROWTH to deal with unexpected growth.
