Characteristics of a Database Clustering with RAC Database Deployment
This topic does not apply to Oracle Cloud Infrastructure or to Oracle Cloud at Customer.
When you create a database deployment using the Oracle Database Cloud Service service level and choose the Database Clustering with RAC database type, Database Classic Cloud Service creates a two-node cluster database using Oracle RAC. Each node of the database is housed on a compute node that Database Classic Cloud Service creates using Oracle Compute Cloud Service resources. In brief, Database Classic 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 Grid Infrastructure 18, 12.2.0.1 or 12.1.0.2 (depending on which database version was selected), 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 three Oracle Automatic Storage Management (ASM) disk groups to provide shared storage for database data, the fast recovery area, and the redo logs, and mounts the disk groups as shared file systems on the two compute nodes using Oracle ASM Cluster File System (ACFS).
-
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 a two-node Oracle RAC database on the compute nodes and starts the network listeners for the nodes.
