oracle clusterware造句

• With the release of Oracle Database 10g Release 2 ( 10.2 ), Cluster Ready Services was renamed to Oracle Clusterware.
• Oracle Clusterware is the software which enables the nodes to communicate with each other, allowing them to form the cluster of nodes which behaves as a single logical server.
• When using Oracle 10g or higher, Oracle Clusterware is the only clusterware that you need for most platforms on which Oracle RAC operates ( except for Tru cluster, in which case you need vendor clusterware ).
• Oracle Clusterware is run by Cluster Ready Services ( CRS ) consisting of two key components : Oracle Cluster Registry ( OCR ), which records and maintains the cluster and node membership information; voting disk, which polls for consistent heartbeat information from all the nodes when the cluster is running, and acts as a tiebreaker during communication failures.
