Larry Ellison and his friends former co workers Bob Miner and Ed Oates started the consultancy Software Development Laboratories SDL in SDL built the first version of the Oracle software. The title Oracle comes from the code title of a CIA funded project Ellison had worked on while previously employed by Ampex. 3 Physical and rational structures An Oracle database system identified by an alphanumeric system identifier or SID 4 comprises at least one instance of the application along with data storage. An instance identified persistently by an instantiation numeral or activation id SYS. V_ $ DATABASE. ACTIVA- TION comprises a set of operating system processes and memory 13

14 structures that interact with the storage. Typical processes comprise PMON the process check and SMON the system check. Oracle documentation can bring name to an vigorous database instance as a shared memory realm. 5 Users of Oracle databases bring name to the server face memory structure as the SGA System Global Area. The SGA typically holds cache intelligence such as data buffers SQL commands and client intelligence. In improver to storage the database consists of online redo logs or logs which book transactional past events. Processes can in turn archives the online redo logs into archives logs offline redo logs which supply the base if necessary for data recuperation and for the involving the body standby forms of data replication using Oracle Data Guard. If the Oracle database administrator has implemented Oracle RAC Real Application Clusters then several instances usually on dissimilar servers attach to a middle storage array. This sequence of possible events offers advantages such as better performance scalability and superfluousness. However support becomes more complicated and many sites do not use RAC. In version 10g grid computer science introduced shared means where an instance can use for instance CPU means from another connecting point computer in the grid. The Oracle DBMS can store and do stored procedures and functions in itself. PL SQL Oracle Corporation s proprietary procedural addition to SQL or the target oriented linguistic communication Java can invoke such code objects and or supply the programming structures for writing them. Storage The Oracle RDBMS stores data logically in the form of tablespaces and physically in the form of data files datafiles. 6 Tablespaces can comprise various types of memory segments such as Data Segments Index Segments etcetera. Segments in turn comprise one or more extents. Extents comprise groups of contiguous data blocks. Data blocks form the fundamental units of data storage. Newer versions of the database can also comprise a partitioning characteristic this allows the partioning of tables based on dissimilar set of keys. Specific partitions can then be easily added or 14

15 dropped to support control big data sets. Oracle database management tracks its computer data storage with the support of intelligence stored in the SYSTEM tablespace. The SYSTEM tablespace holds the data lexicon and frequently by default option indexes and clusters. A data lexicon consists of a special assemblage of tables that holds intelligence about all client objects in the database. Since version 8i the Oracle RDBMS also supports locally managed tablespaces which can store space management intelligence in bitmaps in their own headers rather than in the SYSTEM tablespace as happens with the default option lexicon managed tablespaces. Version 10g and later introduced the SYSAUX tablespace which holds some of the tables formerly in the SYSTEM tablespace. Disk files Disk files primarily compose of the following types Data and alphabetical listing files Those files are necessary for the involving the body storage which can compose of the data lexicon data related to the tablespace SYSTEM client data or alphabetical listing data. These files can be managed manually or managed by Oracle itself Oracle managed files. Note that a datafile has to be owned by to exactly one tablespace whereas a tablespace can compose of several datafiles. Redo enter files consisting of all changes to the database being used to convalesce from an instance failing. Note that frequently these files are stored several times for extra security in case of flat circular plate failing. The identical redo enter files are said to be owned by to the same group. Undo files Those special datafiles which can only comprise undo intelligence are being used for recuperation rollbacks and interpret something consistence. Archive enter files Those files are copies of the redo enter files but are usually stored at dissimilar locations. They are necessary for instance to be concerned with concrete problems or data to a standby database or to give a performance recuperation after an instance failing. It is possible to archives to several locations. Tempfiles Those special datafiles are being used exclusively for impermanent storage data being used for instance for big sorts Control data file necessary for database startup. A binary data file that records the involving the body structure of a database and 15
