Oracle Fail Safe
Oracle Fail Safe is a core feature included with every Oracle Database 12c license for Windows 2008 R2, and Windows 2012. It is a high availability software, integrated with Microsoft Failover Cluster, that provides a fast, easy, and accurate way to configure and verify Windows clusters and to automatically fail over Oracle databases and applications.
In the event of a system failure, Oracle Fail Safe works with Microsoft Failover Cluster to restart Oracle databases and applications on a surviving cluster node. With Oracle Fail Safe, you can monitor and fail over:
Oracle Fail Safe also enables flexible fail back when nodes are returned to service; planned failover for rolling cluster upgrades and workload balancing; and scripting of high availability tasks through its command line interface.
