Understanding the CREATE DATABASE Statement (69)

When you execute a CREATE DATABASE statement, Oracle Database performs (at least)
a number of operations. The actual operations performed depend on the clauses that
you specify in the CREATE DATABASE statement and the initialization parameters that
you have set. Oracle Database performs at least these operations:
■ Creates the datafiles for the database
■ Creates the control files for the database
■ Creates the redo log files for the database and establishes the ARCHIVELOG mode.
■ Creates the SYSTEM tablespace
■ Creates the SYSAUX tablespace
■ Creates the data dictionary
■ Sets the character set that stores data in the database
■ Sets the database time zone
■ Mounts and opens the database for use[@more@]
