Hi Friends,

Today, I am going to show you an interesting thing about SQL Server 2016 – Instant File Initialization. We all knew about the Instant file Initialization feature. For those who are not aware about it can click here.

As a DBA, we know the importance of this feature. Instant File Initialization feature helps SQL Server to grow the database files without filling them to zero. Enabling the Instant File Initialization is a step, that is added to SQL Server Installation step list that should be configured just after the installation. Prior SQL Server 2016, if we want to enable this feature, then there are some steps as mentioned below:

  1. Open the Local Security Policy application.
  2. Expand Local Policies, click on User Rights Assignment.
  3. Now double-click on Perform volume maintenance tasks.
  4. Go to Add User or Group and add service account.
  5. Click on Apply.

Now in SQL Server 2016, you don’t need to perform these steps manually. However, SQL Server 2016 Installer will take care of these steps for you. The only thing that you have to select the check box for Grant Perform Volume Maintenance Task privilege to SQL Server Database Engine Service. I found this interesting feature during the installation of SQL Server 2016 on my test box:

HAPPY LEARNING!
