Home -> Community -> Mailing Lists -> Oracle-L -> RE: ASM monitoring in Enterprise Manager
I would first use asmcmd to look for those dead files you suspect to have.
As for the internals, that sounds strange compared with what I typically see in my ASM diskgroups.
Anyway you can get query for more info on all allocated ASM files, including metadata from x$kffil and x$kfdat (see examples below):
select group_kffil group#, number_kffil file#, filsiz_kffil filesize_after_mirr,
filspc_kffil raw_file_size
from x$kffil;
select group_kfdat group#,FNUM_KFDAT file#, sum(1) AU_used
from x$kfdat where v_kfdat='V'
group by group_kfdat,FNUM_KFDAT,v_kfdat;
I hope this can be of help. Cheers,
Luca

Hi ASM gurus
I am trying to find out why when in EM and I look up the page for the Diskgroup the pie graph Disk Group Usage shows the an amount used for internal that is currently 28%.
I have my suspicions that this is from an earlier process of when we refreshed some databases that we now have dead files in ASM. Is there a way to find out the reason ASM wants 28% of my storage for internal?
I cant find any reference to this in any documentation
ASM is on 10.0.2.3
Cheers
