Introduction to cloud
What Is It? Oracle Database Cloud Service gives you a complete Oracle database instance in a virtual machine (VM). It’s the same familiar Oracle database—now in a cloud. You have full access to the features and operations that are available with Oracle Database, but Oracle hosts the VM and cloud storage. And you can perform some database maintenance and management operations with the easy-to-use cloud portal or command-line interface.
Service levels Two service levels are available: The Oracle Database Cloud Service - Virtual Image level includes Oracle Database and supporting software. You have to install this software yourself, and you are responsible for all maintenance operations for this software. You have root privilege, so you can load and run software in the compute environment. You have full administrative privileges for the Oracle database. The Oracle Database Cloud Service level also includes Oracle Database and supporting software. However, the software is installed for you, an Oracle database is created using values you provide when creating the database deployment, and the database is started.
Metering Frequency When creating a database deployment on Oracle Database Cloud Service, you choose one of the following metering frequencies: 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. For deployments that are started in the middle of a month, the price is pro-rated; you pay only for the partial month from the start date.You cannot switch a deployment from monthly to hourly metering frequency after it is created.
Oracle Database Software Release When creating a database deployment on Oracle Database Cloud Service, 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 18c Release 1
Oracle Database Software Edition When creating a database deployment on Oracle Database Cloud Service, you choose one of the following Oracle Database software editions. For detailed information about the included Oracle Database features, options and packs, see the Permitted Features section of Oracle Database Licensing Information User Manual. Standard Edition—Oracle Database Standard Edition, which delivers unprecedented ease of use, power, and performance for workgroup, department level, and Web applications. It includes all the facilities necessary to build business-critical applications. Enterprise Edition—Oracle Database Enterprise Edition, which provides the performance, availability, scalability, and security required for mission-critical applications such as high-volume online transaction processing (OLTP) applications, query-intensive data warehouses, and demanding Internet applications. Enterprise Edition - High Performance—provides all the features of Enterprise Edition, plus many of the available Oracle Database options and management packs. Enterprise Edition - Extreme Performance—provides all the features of Enterprise Edition, plus all of the Oracle Database options and management packs appropriate for use in Oracle Database Cloud Service.
Oracle Database Type Single Instance — A single Oracle Database instance and database data store hosted on one compute node. For more information about this type, see Characteristics of an Oracle Database Cloud Deployment. 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. For more information about this type, see Characteristics of an Oracle Database Cloud Service Deployment Using Oracle RAC.About Database Cloud Service Database Deployments 1-4 Oracle Cloud Using Oracle Database Cloud Service 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. For more information about this type, see Characteristics of a Database Deployment Using Oracle Data Guard. 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. For more information about this type, see Characteristics of an Oracle Database Cloud Service Deployment Using Oracle RAC and Oracle Data Guard.
Oracle Database Type Not all types are available with all combinations of service level and software edition: Single Instance is the only type supported by the Oracle Database Cloud Service -Virtual Image service level. Single Instance is the only type supported by the Standard Edition software edition. The two types that use Oracle RAC are available only with Enterprise Edition -Extreme Performance software edition.

Backing Up and Restoring Databases on Database Cloud Service Backup failed! This time, it was due to insufficient local storage to hold the backup. Since I chose no backup option, Oracle Cloud Service did not allocate storage to perform backups to /u03 file system. The database was created in ARCHIVELOG mode, and the Cloud Service setup a cron job to remove the archivelog files hourly. It took a while to figure out how to add storage to /u03 file system. More storage is added to the standard file systems by using the “Scale up or down Resources” menu item. Added 50G to “Backup Storage Volume”, which is /u03. 6G volume is now 56G.
Backing Up and Restoring Databases on Database Cloud Service Adding disk space alone is not sufficient, need to increase the Fast Recovery Area as well.
Backing Up and Restoring Databases on Database Cloud Service Though backup is scheduled to run periodically using the cronjobs, lets kick off a backup to verify if the added storage in /u03 resolved the backup issue.
Disaster Recovery to the Oracle Cloud
Disaster Recovery to the Oracle Cloud Why to have DR in Cloud? Cloud service providers has in-built high availability so obvious question that comes to your mind is, why do I need to consider Oracle database disaster recovery for my cloud database or Why should I put my DR database in Cloud? Common Reasons Save costs related to running secondary data center Starting point for your Cloud journey Part of end to end move to Cloud
Disaster Recovery to the Oracle Cloud Primary on Premise, DR in Oracle Cloud Using Oracle cloud as DR brings the obvious benefits related to provisioning and maintaining DR site but it has its own challenges and complexities related to network latency, administration and performance. At high level following steps are performed to do this kind of configuration. Create an Oracle instance in Oracle cloud Perform network configuration to enable on premise DB connectivity with cloud DB Drop database created as part of step 1 Instantiate Standby database using primary DB backup Configure Standby database
Disaster Recovery to the Oracle Cloud Primary and DR both in Oracle Cloud Oracle cloud provides fully automated setup of your primary and Standby database. Here your primary and DR both databases reside in Oracle cloud
