  • Oracle DBCS Storage Volumes and File System Layout

    Oracle uses simple and most efficient Storage Volumes and
    File System Layout in Oracle Database Cloud Service (DBCS) for the ease of use
    and management.


    Let’s take a look at the
    Oracle Database Cloud Services Storage Volume and File System Layout in more
    details.

    When you create a database deployment, Oracle Database Cloud
    Services (DBCS) creates the following Storage Layout and File Systems for you.

    Storage Volumes

    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
    10
    GB volume completely allocated to /u04 on the
    virtual machine.
