I am on 11g R2 Linun redhat-5 , i found a strange thing today, i fired audit all on scott.emp by session but when when i see dba_Audit_Trail it is showing me everytime time the command is executed, means if command select * from emp is executed as scott 5 times it is showing me 5 times the rows in dba_Audit_trail, just like by access option. Note i have not executed audit all on scott.emp by access. I just said audit all on scott.emp by session means it should be audit once even if i execute 10 times
