Tuning CA Database Performance

  • Article

Applies To: Windows Server 2003 with SP1

Increasing CA Database Session Limit

By default, the Windows Server 2003 certification authority allows only 20 concurrent sessions to the JET BLUE database, which is used for storing certificate information, and so on. The CA itself can use several connections as well as client enrollment requests or management tools that view the database. In general, the 20 concurrent session limit should be sufficient for most operations. To increase the max session limit, use the following command to increase the maximum number of sessions to 30, which is the highest limit tested with the Windows Server 2003 certification authority:

certutil -setreg DBSessionCount 30

The certification authority must be stopped and re-started for this change to take place.
