asm manual

I. basic information and concepts 1. ASM is an ORACLE automatic storage management software. It uses bare devices and ASM disks. Before using the software, you need to secure the ASM library driver for the corresponding platform. 2. ASM combines multiple disks to form a disk group. The disk group has the advantages of

In earlier versions of ORACLE78, data files could be stored on file systems and bare devices provided by the operating system.ü Shared file system: With the development of IT system, simple bare device storage and operating system to provide file system storage can not meet the needs of business development, in order to improve the system's computing power, Oracle database has developed a variety of highly available architecture, The
