Oracle Beer Stammtisch - ASM & ACFS Storage Internals

This is a deep-dive into the fascinating storage internals of ASM and ACFS.
We'll examine and dissect the ASM storage structures in great detail and you'll
learn how ASM maps data blocks to Exadata grid and cell disks so that you can
selectively read and modify data blocks to simulate lost writes and corruption
scenarios.
Moreover, we'll also look into how ACFS stores files on ASM and how an attacker
could use that knowledge to read and modify data in a multitenant environment
that lacks appropriate security measures.
