hot file 5.1B PK3

How can I find out hot files (most frequent access read/write) in a filesystem in a given period of time?
OS: 5.1B PK3
HW: 2 GS60, 2 DS25
Storate: SAN EVA5000
LSM installed but not being used.
SW: Informix C-ISAM

Thanks,
Zoong

Re: hot file 5.1B PK3

Does the "vfast [-l|-L] hotfiles" command help?

Hi,

interesting command. You will need the advfs-utilities license however.

Re: hot file 5.1B PK3

I would propose:
1) To check last accessed time.
It does sence only if you looking for files accessed say, once per day or hour.
command 'find' may help here.
This one does removal:
find /var/adm/syslog.dated/* -depth -type d -ctime +7 -exec rm -rf {}

2) In Oracle there are Database tools to see file I\O. Maybe, Informix provides the same?
