Storage Volumes and File System Layout
This topic does not apply to Oracle Cloud Infrastructure or to Oracle Cloud at Customer.
When the database deployment is created, the following Oracle Compute Cloud Service storage volumes are created and attached to the two compute nodes.
Storage Volume | Description |
---|---|
boot (two volumes, one for each compute node) |
25 GB volume for operating system files, user directories and swap space. This volume appears as the |
bits (two volumes, one for each compute node) |
70 GB volume for Oracle Database and Oracle Grid Infrastructure software. This volume appears as the |
data (one volume accessed by both compute nodes) |
Shared storage for database files. GB size equal to the value provided in the Usable Data Storage field during the database deployment creation process, with a minimum of 15 GB. This volume appears as the |
fra (one volume accessed by both compute nodes) |
Shared storage for the fast recovery area. GB size depends on the choice of Backup Destination during the database deployment creation process:
This volume appears as the |
redo (one volume accessed by both compute nodes) |
20 GB shared storage volume for redo logs. This volume appears as the |
These storage volumes are mounted on the compute nodes as follows.
File System Mount | Description |
---|---|
swap |
Swap space; 4 GB allocated from the boot Compute Cloud storage volume. |
|
Operating system files; 16 GB allocated from the boot Compute Cloud storage volume. |
|
Operating system kernel; 500 MB allocated from the boot Compute Cloud storage volume. |
|
Oracle product software; the entire bits Compute Cloud storage volume. |
|
Oracle Database data storage; the entire data Compute Cloud storage volume. An Oracle ASM diskgroup named DATA is created on the storage volume and Oracle ACFS is used to mount it. |
|
Database backup storage; the entire fra Compute Cloud storage volume. An Oracle ASM diskgroup named FRA is created on the storage volume and Oracle ACFS is used to mount it. |
|
Database redo logs; the entire redo Compute Cloud storage volume. An Oracle ASM diskgroup named REDO is created on the storage volume and Oracle ACFS is used to mount it. |
