Title: Chapter 1: Database Architecture and ASM
Course: DEPT MC - ORACLE DATABASE MANAGEMENT II > Section: Unit 1 - Database Administration II

Automatic Storage Management (ASM) is a key Oracle Database technology that you should be using
in your environment, even if it has only one database and one database instance. The integration of
the server file system and a volume manager built specifically for Oracle Database files makes your
disk management and tuning task a breeze: Every file object is striped and mirrored to optimize
performance. In addition, nearly all ASM volume management tasks can occur while the volume is
online. For example, you can expand a volume or even move a volume to another disk while users are
accessing it, with minimal impact to performance. The multiplexing features of an ASM cluster
minimize the possibility of data loss and are generally more effective than a manual scheme that
places critical files and backups on different physical drives. And if that isn’t enough, you can use an
ASM instance and its disk groups to service more than one database instance, further optimizing your
investment in disk hardware
