ASM - Overview
• ASM can be used to simplify the administration of <strong>Oracle</strong>
database files. Instead of managing multiple database
files, ASM requires to manage a small number of disk
groups. A disk group is a set of disk devices that ASM
manages as a single, logical unit.
• A particular disk group can be defined as the default disk
group for a database and <strong>Oracle</strong> automatically allocates
storage for and creates or deletes the files associated
with the database object. When administering the
database, there is only referring to database objects by
name rather than by file name.
