Finding out most used/accessed datafile/(s) in my 10g database

edited Mar 9, 2017 9:58AM in Database Administration (MOSC) 11 commentsAnswered

Hi Gurus,

I am after exploring the following problem :

I have huge 10g database which is used both OLTP and Reporting purposes.  I have performance problems.  My manager decided to move the data files from the existing discs to more faster discs.  When we try this while the database is up and running(i.e serving users) we encountered locking problems.

Hence I want to know whether there is any report(awr or something esle)/view/or any other way to find which data file/(s) are most accessed during 24 hours period. If I know this, I can plan downtime to move those hot data files from existing to faster discs.

Howdy, Stranger!
