Third-Party Cold Failover vs. RAC One Node
A third-party technology such as HP's Serviceguard, IBM's HACMP, or Veritas' Cluster Server can be used to
address unplanned server outages. These technologies manage a database in active/passive configuration to offer
failover solutions to a single-instance database. In the event of a server failure, the passive instance on the other
node will be started manually or with automated scripts. However, application connections need be redirected to
the active instance.
