There are 18 LIOs per insert=2E
There are 3 indexes on the table, none are functional=2E
Using you formula I should have 10 LIOs per table so yes, my number is=20=
bigger than the simple calculation=2E

RE: LIOs on INSERT?
Hi Patty,
How many LIOs per one insert do you have?
How many indexes do you have on the table?
Hope no functional indexes :)
Simple algorithm for LIO for simple insert should be =3D
N*M + X
where N =3D number of indexes
M =3D depth level (usually up to 4 on big tables)
X =3D number of blocks the insert can fit into (1 for
normal size row)
Is your number bigger then with this simple formula?
Regards,
Zoran Martic
