Troubleshooting: BlackBerry Enterprise Server Performance

A BlackBerry Enterprise Server that you installed remotely from the BlackBerry Configuration Database uses an unexpected amount of system resources and increases wireless network traffic

Possible cause

Once daily, the BlackBerry® Enterprise Server uses the BlackBerry Mailstore Service to refresh the user information from your organization's address book in the BlackBerry Configuration Database. If multiple BlackBerry Enterprise Server instances are associated with a BlackBerry Configuration Database, each BlackBerry Enterprise Server instance tries to use a BlackBerry Mailstore Service to refresh the address book information in the BlackBerry Configuration Database. The first BlackBerry Mailstore Service that starts the refresh process is responsible for completing it.

If the BlackBerry Mailstore Service that is responsible for completing the refresh process is associated with a BlackBerry Enterprise Server that is geographically remote from the BlackBerry Configuration Database, the BlackBerry Mailstore Service can take an unexpected amount of time to complete the refresh process. The refresh process can use an unexpected amount of system resources and increase wireless network traffic.

Possible solution

You can use TraitTool.exe to turn off the address book refresh feature for BlackBerry Enterprise Server instances that are geographically remote from the BlackBerry Configuration Database. As a result, BlackBerry Enterprise Server instances that are located geographically close to the BlackBerry Configuration Database can use the BlackBerry Mailstore Service to refresh the user information from your organization's address book in the BlackBerry Configuration Database.

TraitTool.exe is located in the Tools directory on the BlackBerry Enterprise Server installation media.

  1. At the command prompt, navigate to the folder that TraitTool.exe is located in.
  2. Type: TraitTool -host <name> -trait MailstoreAddressRefreshEnabled -set False, where <name> is the name of the BlackBerry Enterprise Server instance.
  3. Press ENTER.

To turn on the address book refresh feature for a BlackBerry Enterprise Server again, use the same command with a value of True.

Microsoft SQL Server uses a considerable amount of disk space

Possible cause

Reorganizing or rebuilding an index in Microsoft® SQL Server® can cause the size of the transaction log file in the BlackBerry® Configuration Database to grow larger than expected.

Possible solution

Add the following tasks to the end of your organization's regular maintenance plan:

  1. Perform a complete backup of the transaction log file.
  2. Perform a shrink log file task on the transaction log file.
