If you do not specify which partition the bcp sessions should use, Adaptive Server randomly assigns the multiple bcp sessions to the table’s available partitions.
dbcc checktable – to periodically to check the total page counts for each partition
sp_helpsegment or sp_helpartition – to perform a similar check, but without locking the database objects
For more information about dbcc checktable, see the System Administration Guide. For more information about sp_helpsegment and sp_helpartition, see the Reference Manual.
