• sends IT policies and service books that you update to all BlackBerry devices that are associated with the BlackBerry
Enterprise Server instance that the BlackBerry Policy Service runs on
• sends updated PIN encryption keys to all devices that are associated with the BlackBerry Enterprise Server instance
that the BlackBerry Policy Service runs on
• performs an application poll to verify whether the BlackBerry Policy Service must send applications to all devices that
are associated with the BlackBerry Enterprise Server instance that the BlackBerry Policy Service runs on
You can configure BlackBerry Policy Service throttling using the BlackBerry Enterprise Trait Tool. You can access the
BlackBerry Enterprise Trait Tool in the Tools folder of the BlackBerry Enterprise Server installation files.

If the BlackBerry Enterprise Trait Tool does not list any BlackBerry Policy Service throttling traits, no BlackBerry
Policy Service throttling traits have been changed from their default values.
Configuring BlackBerry Policy Service throttling for ITpolicies and service books
If the BlackBerry Policy Service detects that you updated an IT policy or service book in the BlackBerry Configuration
Database, it schedules a task to create and deliver the IT policy or service book to BlackBerry device users that must
receive the update. The BlackBerry Policy Service tries to process tasks as fast as the server permits, which can result in an
unexpected increase in CPU usage and database usage.
Because you cannot synchronize multiple BlackBerry Policy Service instances on multiple BlackBerry Enterprise Server
instances, an update to an IT policy or service book that affects many users on multiple BlackBerry Enterprise Server
instances can increase the CPU usage and database usage significantly for a long period of time. The increased CPU usage
and database usage can lead to unexpected behavior such as database updates not completing.
To avoid this scenario, you can throttle the processing of IT policies and service books. You can specify the maximum
number of processes for IT policies and service books that a BlackBerry Policy Service can run at one time before the
BlackBerry Policy Service schedules additional processes for IT policies and service books. You can also specify the
maximum number of IT policies and service books that a BlackBerry Policy Service can send to devices each minute and
