what is the impact on fixed_objects_stats or x$ when changing init parameter _user_adaptive_log_file

edited Nov 27, 2014 10:03AM in Database Tuning (MOSC) 3 commentsAnswered

Per Oracle Support, the _use_adaptive_log_file_sync was changed to false from true to address 'log_file_sync' issue on RAC 4-node database.

What is the impact on x$ table and fixed_objects_stats after modifying _use_adaptive_log_file_sync parameter?

Is it run DBMS_STATS.GATHER_FIXED_OBJECT_STATS after such an init parameter change helps the Optimizer?

Howdy, Stranger!
