Real Application Clusters
General Purpose Cluster Configuration
The General Purpose Cluster is a new cluster deployment that requires minimum network and storage configuration and supports applications that benefit from managed server restarts and failover capabilities. Oracle Grid Infrastructure installer provides a streamlined option to configure a general-purpose cluster in either interactive or silent mode.
This feature increases productivity and reduces the required deployment time by simplifying deployment requirements.
Local Rolling Database Maintenance
Local Rolling Database Maintenance creates a new local database home and starts a second instance of the same database from the new home on the same server, allowing you to perform rolling patching and maintenance operations locally on one node of a multi-node Oracle Real Application Clusters (Oracle RAC) or Oracle RAC One Node cluster.
Local Rolling Database Maintenance provides uninterrupted database availability during maintenance activities (such as patching) for Oracle RAC and Oracle RAC One Node databases. This feature significantly improves the availability of your databases while limiting the impact on other nodes in the cluster.
Single-Server Rolling Database Maintenance
Single-Server Rolling Database Maintenance creates a new local database home and starts a second instance of the same database from the new home on the same server, allowing you to perform rolling patching and maintenance operations on a single server hosting an Oracle RAC One Node or Real Application Clusters (Oracle RAC) database.
Single-Server Rolling Database Maintenance provides database availability during maintenance activities (such as patching) on a single server hosting an Oracle RAC or Oracle RAC One Node database. This feature significantly improves the availability of your single-node databases without expanding them to a multi-node cluster and adding support for shared storage.
