System Global Area. It is made up of the database buffer cache, shared pool and redo log buffer. Basically this is any data and program caches that are shared among database users.
System Global Area. The SGA is a shared memory region Oracle uses to store data and control information for one Oracle instance. The SGA is allocated when the Oracle instance starts; it is deallocated when the Oracle instance shuts down. Each Oracle instance that starts has its own SGA. The information in the SGA is made up of the database buffers, the redo log buffer, and the shared pool; each has a fixed size and is created at instance startup.
System Global Area. A memory region within main memory used to store data for fast access. Oracle uses the shared pool to allocate SGA memory for shared SQL and PL/SQL procedures.
System Global Area. An area of memory used for database information shared by the database users.
System Global Area. The shared memory region that is used to store data and control information for one Oracle instance. Each Oracle instance has its own SGA; the SGA is allocated when the instance starts, and is deallocated when the instance is shut down. The SGA is comprised of the database buffers, the redo log buffer, and the shared pool.
System Global Area. A group of shared memory structures that contain data and control information for an Oracle instance.
System Global Area. A shared storage area that contains information required by user processes and background processes, such as data and control information for one Oracle instance. The SGA is allocated when an Oracle instance is started, and is deallocated when the instance shuts down.
The System Global Area ( SGA) is an area of memory allocated when an Oracle Instance starts up. The SGA's size and function are controlled by INIT.ORA (initialization) parameters. The SGA is composed of areas like the Shared Pool, Buffer Cache, Log Buffer, etc.
