154.41 MB of Audit Trail files collected (.aud: 154.41, .xml: 0, .bin: 0)

Enterprise Manager giving error 'Audit Trail files collected' after EM upgrade to 12.1.0.5.0

Current 'Database Instance' template was showing:

> Operating System Audit Records

> > File Count [>=, 10, 20]

After hours of investigating found my ideal fix for our environment.


Fix: Created a new 'Database Instance' and applied to database.

Now we got the desired option

> Operating System Audit Records

> > Size of Audit Files [>=, 10, 20]

After updating above numbers to 1024, 1280 and applying the template to database, above alert has gone. Selected 1GB and 1.2GB, since we the space and for all 40+ rac's size of current audit folders were 100 - 800 MB.
