Oracle Database Cloud Services (DBCS) Overview

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.

Service Level

Service Level	Details
Oracle Database Cloud Service - Virtual Image	Compute Allocated Storage Allocated Virtual Machine Image Installed Included software to create Oracle Database Connect to VM and run DBCA to create Database You are responsible for maintenance operations such as Backup , Patching and Upgrade

Metering Frequency

Frequency	Description
Hourly	Pay only for the number of hours used during your billing period. You cannot switch a deployment from hourly to monthly metering frequency after it is created.
Monthly	Pay one price for the full month irrespective of the number of hours used. You cannot switch a deployment from hourly to monthly metering frequency after it is created.

Cloud Tooling for Database Cloud Service

Purpose	Tool	Description
Automated Backup	bkup_api	To perform on-demand backup and change how automatic backups are configured. Use raccli for Real Application Clusters deployment.
Automated Recovery	dbaascli	To perform restore/recovery. Use raccli for RAC deployment.
Automated Patching	dbaascli	To apply patches. Use raccli for RAC deployment
Database Monitoring	DBaaS Monitor	To monitor Oracle Database and Computing Resources

Oracle Database Software Release

When creating a database deployment on Oracle Database Cloud Service (DBCS), you choose one of the following Oracle Database software releases:

• Oracle Database 11g Release 2
• Oracle Database 12c Release 1
• Oracle Database 12c Release 2

Oracle Database Type

Database Type	Description
Single Instance	A single Oracle Database instance and database data store hosted on one compute node.
Database Clustering with RAC	A two-node clustered database using Oracle Real Application Clusters technology; two compute nodes each host an Oracle Database instance, and the two instances access the same shared database data store.
Single Instance with Data Guard Standby	Two single-instance databases, one acting as the primary database and one acting as the standby database in an Oracle Data Guard configuration.
Database Clustering with RAC and Data Guard Standby	Two two-node Oracle RAC databases, one acting as the primary database and one acting as the standby database in an Oracle Data Guard configuration.
Data Guard Standby for Hybrid DR	Single-instance database acting as the standby database in an Oracle Data Guard configuration. The primary database is on your own system.

Automatic Backup Configuration

When you create a new database deployment on DBCS, you can choose whether you want to configure automatic backup for your database.

Backup Option	Description
Both Cloud Storage and Local Storage	30 days worth of backups are kept, with the 7 days most recent backups available directly on the compute node’s local storage.
Cloud Storage Only	30 days worth of backups are kept, with all backups on cloud storage.
None	No automatic backups are configured
