Hi! I am preparing new, just installed, Oracle Linux 7.6 operating system for Oracle Database 12cR2 use. I tried to execute these recommendations from "Oracle® Database Administrator's Reference 12c Release 2 (12.2) for Linux and UNIX-Based Operating Systems E85783-02 February 2018" document, B.7.4 "Configuring HugePages on Linux" part:

I have few questions for the community about this document explanation:

1. In document's example server has 64 Gb RAM, so when I will calculate formulae 64*1024*1024*0.9, I will get 60397977,6 KB really. In the document I see just 60397977 KB, so we are loosing 0.6 KB. I know this is very little number, but why we doesn't round up our real number to nearest upper integer, for example 6039797

Howdy, Stranger!
