KB11719 - New Data Source ID results in constant slow synchronization
KB11719 - New Data Source ID results in constant slow synchronization
Environment
- BlackBerry® Enterprise Server version 4.1 SP2 and earlier
- IBM® Lotus® Domino® 7.0.2
- SDR111207
Overview
When the new application programming interface (API) call was used (NSFDbModifiedTimeByName), a new Data Source ID was created and caused a slow sync.
The problem occurs immediately after adding a contact to the address book. The API call is made to check for modified documents. The problem eventually occurs on its own because the BlackBerry Enterprise Server makes the call automatically at regular intervals.
Cause
In environments using BlackBerry Enterprise Server version 4.1 SP2 and IBM Lotus Domino 7.0.2, Data Source IDs are created when BlackBerry smartphone users add a new contact to address books configured to use an external database. This causes a slow sync of the BlackBerry smartphone user’s address book.
Resolution
Apply BlackBerry Enterprise Server version 4.1 SP2 HF2 or later.
Workaround
To stop the constant slow synchronization, complete the following steps: - On the computer on where the BlackBerry Enterprise Server is installed, start the Registry Editor.
- In the left pane, browse to HKEY_LOCAL_MACHINE\SOFTWARE\Research In Motion\BlackBerry Enterprise Server\Agents\
- Create the DWORD value DontUseModifiedByName.
- Enter 1 to prevent the functionality. The DWORD DontUseModifiedByName = "1" stops the constant slow synchronization.
