What are the file systems and volume management techniques used in oracle rac?
Answer / Sania Zehra
In Oracle RAC, the following file systems and volume management techniques can be used:
- Shared SCAN (Shared Server Connection): It is a connection method used by the database instances to share resources such as memory and CPU.
- ASM (Automatic Storage Management): It is a storage management tool that automates the creation, maintenance, and backup of database files.
- OCFS2 (Oracle Cluster File System 2): It is a clustered file system for Linux-based Oracle RAC environments.
- DAS (Direct Attached Storage): It is used in some Oracle RAC implementations where shared storage is not available or desired.
