If num is -1 then dbmlsync retries an interrupted synchronization until it completes, successfully or unsuccessfully, without being
interrupted. If num is 0 then dbmlsync does not retry the interrupted synchronization. If num is greater than 0 then dbmlsync retries the synchronization up to num times until it completes. After num attempts, if the synchronization has not completed, then it is run as a foreground synchronization so it will complete without
By default BackgroundRetry is 0. It is an error to set BackgroundRetry to a non-zero value when the Background option has
not been set to TRUE. See -bk dbmlsync option.
The BackgroundRetry is ignored when the dbmlsync API or the SQL SYNCHRONIZE statement is used.
