Large MMNL trace file

edited Apr 28, 2010 5:23AM in Database Administration (MOSC) 4 commentsAnswered
I have 2 mmnl trc files in my bdump directory. One is 1.3g in size and contains data from 15th Feb 2010 to April 21st, the other is 68M and contains data from 21st April to today. I am trying to understand what creates these files, and whether they can be switched off / deleted / housekept safely while the database is still up and running?

Thanks
