Automatic Storage Management (ASM) was first released with Oracle Database 10g. For Oracle databases, ASM provided a significant simplification for file system and volume management. In addition to enhancing storage automation, ASM improved file system scalability, performance, and database availability. These benefits hold for both single-instance Oracle databases as well as for Oracle Real Application Clusters (Oracle RAC) database environments. Oracle Database 12c introduces several new capabilities in ASM. This whitepaper presents these advances and is targeted at a technical audience mainly comprising:

  • Database, system and storage administrators
  • Architects
  • Consultants
  • System engineers
  • Technical managers
ASM Overview

ASM is a feature of Oracle database providing an integrated cluster file system and volume manager at no additional cost. ASM lowers the Oracle database storage total cost of ownership and increases storage utilization while improving performance and availability as compared with traditional file system and volume management solutions. With ASM, less effort is required for managing your database storage environment.

ASM is easier to manage than conventional file systems, it optimizes the performance of your storage hardware, and is tightly integrated with the Oracle Database. Additionally, ASM eliminates the need for 3rd-party volume managers and file systems for managing the Oracle database files
