RMAN stands for ____________________.

____ logs are copies of old redo log files,copied just before redo log files are reused.

How fast does data change in an OLTP database and in a data warehouse? How does this affect recoverability?

____________________ is the process of executing procedures in Oracle Database to update the recovered backup files to an up to date state.

A(n)____ backup or recovery requires a database to be completely shut down for the backup,and sometimes the recovery process as well.

____ is the process of making some kind of copies of parts of a database,or an entire database.

Typically,many database installations will use a combination of both disk and tape backup storage.

Oracle backup and recovery is actually broken up into ____ separate actions.

OLTP databases are often required to be available on a 24-hour basis.

Restoration of a recovered backup is a simple process of applying redo log entries to the datafile,until the datafile "catches up" to the time indicated by the archive log.

If you ever need to restore from a cold backup,you would need to restore at least all the datafiles and controlfiles.

The redo log buffer is always larger than the database buffer cache.

A(n)____________________ tablespace is a physical copy of a tablespace (containing data),plus an export utility dump of metadata (from the SYSTEM tablespace).

An abort shutdown of a database,or a power failure,kills all processes and clears all memory buffers immediately,regardless of what is executing in the database.

Flashback technology relies generally on a combination of undo data,and ____.

Recovery of a controlfile does not actually involve any kind of recovery process,but rather one of restoration or rebuilding of the controlfile.
