Storage Volumes and File System Layout

Not Oracle Cloud Infrastructure This topic does not apply to Oracle Cloud Infrastructure.

This section provides information about the storage volumes and file system layout of a newly created database deployment on Oracle Database Cloud Service.

Compute Cloud Service Storage Volumes

When a Database Cloud Service deployment is created using the Oracle Database Cloud Service service level, the following storage volumes are created.

Storage Volume Description

bits

60 GB volume completely allocated to /u01 on the virtual machine.

boot

32 GB volume allocated to the following file system mounts on the virtual machine:

  • / (root)

  • /boot

  • swap space

data

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 is completely allocated to /u02 on the virtual machine.

fra

GB size depends on the choice of Backup Destination during the database deployment creation process:

  • Both Cloud Storage and Local Storage: GB size equal to 1.7 times the size of the data volume.

  • Cloud Storage Only or None: GB size equal to 0.1 times the size of the data volume, with a minimum of 7 GB

    .

This volume is completely allocated to /u03 on the virtual machine.

redo

25 GB volume completely allocated to /u04 on the virtual machine. (If the data volume is 25 GB, then the redo volume is allocated 26 DB instead.)

File System Layout

When a database deployment is created using the Oracle Database Cloud Service service level, Oracle Cloud Service storage volumes are created and allocated as follows.

File System Mount Description

swap

Swap space; 4 GB allocated from the boot Compute Cloud storage volume.

/ (root)

Operating system files; 25.5 GB allocated from the boot Compute Cloud storage volume.

/boot

Operating system kernel; 500 MB allocated from the boot Compute Cloud storage volume.

/u01

Oracle product software; the entire bits Compute Cloud storage volume.

/u02

Oracle Database data storage; the entire data Compute Cloud storage volume.

/u03

Database backup storage; the entire fra Compute Cloud storage volume.

/u04

Database redo logs; the entire redo Compute Cloud storage volume.
