Answer / nishi
When an instance of an ORACLE database is started, its control file is used to identify the database and redo log files that must be opened for database operation to proceed. It is also used in database recovery.
Controlfile contains the information about the database like names and locations of datafiles, name of the database, database creation timestamp and apart from this the SCN are also reported into control during the database operation. Especially during the database startup the controlfile is used to gather the information about the database and while opening the database the information in the controlfile is validated to check for the consistency of the database.
