Auditing and Performance

By default, the Policy Server writes audit events to a text file, which is known as the Policy Server log. Optionally, you can configure the Policy Server to log events to an audit database.

Note: For more information about configuring the Policy Server to log events to an audit database, see the Policy Server Administration Guide. For more information about configuring an audit database, see the Policy Server Installation Guide.

Consider the following factors if you decide to log events to an audit database:

• Performance associated with authentication and authorization is affected because SiteMinder is logging all authentication and authorization decisions to the database.
• (Optional) Synchronous logging—You can configure synchronous logging at the realm level. If configured, the Policy Server prevents the result of each authentication and authorization request until the record is saved in the audit database. Users are not authenticated or authorized until the record is saved.
