問題文
A single server will run one database, and the site wants the database, the listener and the storage layer to come back by themselves after the host restarts. Which statement describes what has to be installed for that?
選択肢
- The database software alone is installed, and the components that have to come back are then listed in the parameter file of that database so that the instance brings each of them up after the host restarts.
- The clusterware for several servers is installed, and the components that have to come back are then registered with it so that another server in the cluster takes them over after the host restarts.
- The database software is installed twice into two homes, and the components that have to come back are then divided between the homes so that one of them starts the other after the host restarts.
- The grid software for a single server is installed into a home of its own, and the components that have to come back are then registered with it so that it brings each of them up after the host restarts.
