    Tempfiles: These special datafiles serve exclusively for temporary storage data used for example during large sorts or for global temporary tables Control files, necessary for database startup. Oracle Corporation defines a control file as "[a] binary file that records the physical structure of a database and contains the names and locations of redo log files, the time stamp of the database creation, the current log sequence number, checkpoint information, and so on".

    Data files can occupy pre-allocated space in the file system of a computer server, use raw disk directly, or exist within ASM logical volumes. After the installation process sets up sample tables, the user logs into the database with the username scott and the password tiger. Other default schemas [83] [84] include: SYS essential core database structures and utilities SYSTEM additional core database structures and utilities, and privileged account OUTLN used to store metadata for stored outlines for stable query-optimizer execution plans.

    The information in the SGA consists of the following elements, each of which has a fixed size, established at instance startup: Datafiles Every Oracle database has one or more physical datafiles, which contain all the database data.

    The data of logical database structures, such as tables and indexes, is physically stored in the datafiles allocated for a database. Datafiles have the following characteristics: One or more datafiles form a logical unit of database storage called a tablespace.

    A datafile can be associated with only one tablespace. Datafiles can be defined to extend automatically when they are full.

    Data in a datafile is read, as needed, during normal database operation and stored in the memory cache of Oracle Database. For example, if a user wants to access some data in a table of a database, and if the requested information is not already in the memory cache for the database, then it is read from the appropriate datafiles and stored in memory.

    Modified or new data is not necessarily written to a datafile immediately. To reduce the amount of disk access and to increase performance, data is pooled in memory and written to the appropriate datafiles all at once. The instance writes redo log buffers to the redo log as quickly and efficiently as possible.
