_use_adaptive_log_file_sync

edited Sep 16, 2015 8:39AM in Database Administration (MOSC) 5 commentsAnswered ✓

Hi,

I am trying  to understand the log file sync wait events.

As both Post/wait  and Polling  have their own advantages and disadvantages under heavy load conditions.

To avoid/ reduce  log file sync wait events in 11.2.0.3 ,we may disable lGWR switcing   by setting _use_adaptive_log_file_sync  to False.

If we disable _use_adaptive_log_file_sync , LGWR uses conventional method , to flush the log buffer data , Which one is the Conventional method ?

-Thanks
