Upgrade Guide
Improve the startup performance of the BlackBerry Enterprise Server
after the upgrade
After an upgrade, the BlackBerry® Enterprise Server might send new service books to every BlackBerry device. If it sends all
the new service books at the same time, the BlackBerry Enterprise Server startup time might be affected. You can improve
the startup performance of the BlackBerry Enterprise Server by configuring the number of service books that the BlackBerry
Enterprise Server sends each hour.
1.
On the computer that hosts an upgraded BlackBerry Policy Service, on the taskbar, click Start > Run. Type regedit.
2.
In the left pane, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Research In Motion\BlackBerry Enterprise Server
\BlackBerry IT Admin Server.
3.
Right-click BlackBerry IT Admin Server. Click New > DWORD Value.
4.
Create the following DWORD values if they do not already exist:
• SBThrottlingEnabled: Right-click the new value. Click Modify. Set the Value data to 1.
• SBThrottleLimit: Right-click the new value. Click Modify. Set the Value data, in decimal format, to the maximum
number of service books that you want the BlackBerry Enterprise Server to send each hour. The default is .60, which
means that the BlackBerry Enterprise Server sends 60 new service books each hour.
