User Global Area (UGA)The UGA is memory associated with a user session Software code areasSoftware code areas are portions of memory used to store code that is being run or can be run.
The SGA is shared by all server and background processes Examples of data stored in the SGA include cached data blocks and shared SQL areas.

The collection of individual PGAs is the total instance PGA, or instance PGA Database initialization parameters set the size of the instance PGA, not individual PGAs.. Figure 14-1 illustrates the relationships among these memory structures Figure 14-1 Oracle Database Memory StructuresDescription of 'Figure 14-1 Oracle Database Memory Structures'Oracle Database Memory ManagementMemory management involves maintaining optimal sizes for the Oracle instance memory structures as demands on the database change.

The memory area stores information such as the following:Program codeInformation about each connected session, even if it is not currently activeInformation needed during program execution, for example, the current state of a query from which rows are being fetchedInformation such as lock data that is shared and communicated among processesCached data, such as data blocks and redo records, that also exists on diskBasic Memory StructuresThe basic memory structures associated with Oracle Database include:System global area (SGA)The SGA is a group of shared memory structures, known as SGA components, that contain data and control information for one Oracle Database instance.. This chapter contains the following sections:See Also:Oracle Database Administrator's Guide for instructions for configuring and managing memoryIntroduction to Oracle Database Memory StructuresWhen an instance is started, Oracle Database allocates a memory area and starts background processes..

Oracle Database code is stored in a software area that is typically at a different location from user programs—a more exclusive or protected location.. The database instance automatically tunes to the target memory size, redistributing memory as needed between the SGA and the instance PGA. Best Desktop Mail App For Mac
If you create a database with Database Configuration Assistant (DBCA) and choose the basic installation option, then automatic memory management is the default.. The PGA is created by Oracle Database when an Oracle process is started One PGA exists for each server process and background process..

Program global area (PGA)A PGA is a nonshared memory region that contains data and control information exclusively for use by an Oracle process.. Automatic shared memory managementThis management mode is partially automated You set a target size for the SGA and then have the option of setting an aggregate target size for the PGA or managing PGA work areas individually.. Oracle Database manages memory based on the settings of memory-related initialization parameters..
