- Uncategorized

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.

December 19, 2017

- Uncategorized

Oracle Database Cloud Service (DBCS) provides you the ability to deploy Oracle databases in the Oracle Cloud. Each database deployment contains a single Oracle database in a Virtual machine image. You can’t create multiple databases in one database deployment if you want to create multiple databases then you create a 12c Container database with multiple Pluggable databases. Oracle DBCS or also known as DBaaS is part of Platform as a Service (PaaS) offering. The compute, virtual machine, storage, network, optionally tools to simplify routine database maintenance and management operations are provided by Oracle. You will have full access to the features and options available with Oracle Databases.

When you create a database deployment, Database Cloud Service creates compute nodes to host the database, using computing, storage and networking resources provided by various Oracle Cloud infrastructure services.
