SHARE means that dbmlsync locks all synchronization tables in shared mode. EXCLUSIVE means that dbmlsync locks all synchronization
tables in exclusive mode. For all platforms except Windows Mobile, ON is the same as SHARE. For Windows Mobile devices, ON
is the same as EXCLUSIVE.
The default is OFF. By default, dbmlsync does not lock any synchronization tables except for the following situations:
If there is a publication that uses script-based upload in the current synchronization or if there is an sp_hook_dbmlsync_schema_upgrade
hook defined in the remote database, dbmlsync locks the synchronization tables with SHARE.
Set to ON to prevent modifications during synchronization.
When synchronization tables are locked in exclusive mode (the default for Windows Mobile devices), no other connections can
access the tables, and so dbmlsync stored procedures that execute on a separate connection are not able to execute if they
require access to any of the synchronization tables.
