Characteristics of a Single Instance with Data Guard Standby Database Deployment

This section provides information about the content and configuration of a newly created Oracle Database Cloud Service database deployment that uses the Oracle Database Cloud Service service level and the Single Instance with Data Guard Standby database type.

When you create a database deployment using the Oracle Database Cloud Service service level and choose the Single Instance with Data Guard Standby database type, Database Cloud Service creates an Oracle Data Guard configuration with a primary database and one physical standby database. Each database is a single-instance Oracle database housed on a compute node that Database Cloud Service creates using Oracle Compute Cloud Service resources. In brief, Database Cloud Service:

  • Creates two compute nodes that are alike in all respects except that each one has its own public IP address.

  • Installs Oracle Linux 6.6, Oracle Database 18, 12.2.0.1, 12.1.0.2 or 11.2.0.4 (depending on which version was selected), and cloud tooling software on each of the compute nodes.

  • Creates storage for database data, the fast recovery area, and the redo logs.

  • Creates Oracle Compute Cloud Service networking resources to provide access to the compute nodes, setting all except SSH access on port 22 to a disabled status.

  • Creates and starts an Oracle database on each compute node and starts the network listener for each node.
