Re: OS bloack size and ORACLE BLOCK SIZE

The default block size is 8K with a fragment size of 1K i.e. files with size below 8K are allocated using 1K blocks increments and files larger than 8K are done in 8K increments except for the last block which may be a fragment.

Hi Everyone i'm trying to determine what my os block size is My DB's have an 8k block size and i thought for best performance my os block size should be the same.

So i run the command "df -g"

           8192 file system block size 1024 fragment size is the result

and i run the command "fstyp -v /dev/dbvg/dblv" f_bsize: 1024
f_frsize: 1024
is the result

so what is my os block size, aren't these commands returning my filesystem block size, or is that the same thing.
If i'm completly wrong how do i find out my OS block and should my filesystem block be the same as that?
i'm on HPUX 10.20

Thanks David Hill
