Course Description
Overview
In this class students will learn how to install, configure and manage Oracle (ASM) and the Oracle Clustered File System (ACFS). This is a fully instructor-led class with demonstrations and hands-on workshops.ASM / ACFS is much more than a storage platform for Oracle databases: it can also replace third party file servers and clustered file systems, acting as a highly available and fault tolerant storage medium that can be used by any application. Learn why ASM and Automatic Storage Management Cluster File System (ACFS) are so important for performance and reliability of Oracle systems and how to exploit their capabilities to the full and why ASM is the best performing storage option available for Oracle Databases.
