SGA and PGA are parts of the memory architecture of Oracle Database. (System Global Area)SGA is is a group of shared memory areas that are dedicated to an Oracle instance (Program global area)PGA is a memory region that contains data and control information for a server process. It is nonshared memory created by Oracle Database when a server process is started. Access to the PGA is exclusive to the server process. There is one PGA for each server process. Background processes also allocate their own PGAs.

CAPTIONS AVAILABLE - I assume that it's the "I like!" votes that keep this video at or near the top when you search on "oracle". Thank you to all. S. Faroult View on www.konagora.com where Youtube is blocked. Full transcript (with some screenshots) available for a small fee at http://stores.lulu.com/konagora/. A pretty reckless description of what happens when you start Oracle and when you execute a statement. If you're a developer, it could influence how you code. If you're a junior DBA, or would be junior DBA, I hope it will help you make sense of some parts of the "Concepts" manual.

How to increase/decrease memory_target in 11g ====================================================== oracle 10g --sga_target (parameter new in 10g) oracle 11g --memory_target (parameter new in 11g) How to check whether the parameter is static or dynamic? ========================================================= select name, value, issys_modifiable from v$parameter where name like '%¶meter%' ; if issys_modifiable=false --- parameter is static (database bounce required) if issys_modifiable=immediate --- parameter is dynamic (database bounce not required) (note: consider using spfile) sql commands ================ show parameter memory; alter system set memory_target=350m scope=spfile; alter system set memory_max_target=350m scope=spfile;

This video describes the best architecture of the oracle after trying more than times to Oracle structure I decided to produce an animated video let's start first with the database structure on the left side you have the client here on the right side you have to serve a two-year the server side is divided in three main structures to memory the logical structure and the physical structure so let's use SQL Plus application to provide you every step up a transaction will be using Scott sample schema it is important to note that the whole string is an alias and not a database name district will be compared to this alias inside of a file called pianist named doc or this file is similar to a DNS and with up pain all the necessary detail to reach a database server locally a user process will be allocated and will validate the connection through a listener the listener will be in charge to allocate a server process the user processes da link to the server process let's now execute our first transaction for this example we will execute an update first to state that will be validated we call this step the parsing this server process sense back to confirmation of the parsing that statement with be written into their share pool and the redo log buffer an execution plan will also be created it to the fair share Paul that database book they choose fought the transaction will be read and copy into the database buffer cache only that feel implicated in that transaction will be held it to a - segment till the transaction is completed we call those copies the before image a copy of this block will be duplicated with the updated feel this copy is called me after image a confirmation will be sent to to use a process the commit statement will complete the transaction and will be written into to redo log buffer to commit statement triggers the log writer process and we'll send all statement for the current transaction into the redo log file the before image into undo segment could be then deleted went that threshold up to undo retention parameters reach alaskan from Asian will be sent to the user process went to current law kiss Paul it generates a switch lock triggering at the same time the archiver process and to log sequence number the archiver will generate and archive the file with the content of the current loc a switch up with them trigger a checkpoint process that will incriminate the checkpoint number by applying this last number into each data file header the checkpoint process with finally trigger the database writer process enright the last image from that database buffer cache into thirty people

강의 자료(PDF) 다운로드: https://goo.gl/VZovDV - Oracle Server가 시작될 때마다 시스템 전역 영역(SGA: System Global Area)이 메모리에 할당된다. - SGA는 Oracle DBMS에 대한 데이터와 제어 정보를 갖고 있는 공유 메모리 그룹이다. - SGA의 데이터는 여러 사용자 간에 공유된다. - SGA는 종종 "공유 전역 영역 (Shared Global Area)" 이라고 부르기도 한다 .
