Wrong calculation in OracChk "Verify Datafile's Logical and Physical Size"

Hi all,

I executed OraChk from AHF v.21.2.3 for all of my Databases 19.12.

On Check-ID B82BEA8B546919FCE053D398EB0A514B ("Verify Datafile's Logical and Physical Size") it listed EVERY datafile > 10.000.000.000 Bytes.

The output in the HTML assessment reports is like this:

Status on testsrv:
WARNING => Logical and physical size of all datafiles are not same

DATA FROM testsrv - ORATEST DATABASE - Verify Datafile's Logical and Physical Size
