20 Oracle TimesTen 구성방안 Centralized vs Distributed

21 Centralized TimesTen 구성 ( 2 ) ( 3 ) ( 1 ) ( 6 ) Oracle TimesTen WAS ( 5 ) ( 4 ) ( 1 ) HTTP Request ( 2 ) SELECT 조회 ( 3 ) SELECT 결과리턴 ( 4 ) DML 수행 (PassThrough SQL) ( 5 ) DML 결과데이터반영과 AutoRefresh(Oracle RDBMS > TimesTen) Oracle 10g 21

22 Distributed TimesTen 구성 WAS ( 1 ) ( 2 ) WAS ( 3 ) ( 4 ) Oracle 10g ( 5 ) ( 1 ) HTTP Request WAS ( 2 ) SELECT 조회 ( 3 ) SELECT 결과리턴 ( 4 ) DML 수행 (PassThrough SQL) ( 5 ) DML 결과데이터반영과 AutoRefresh(Oracle RDBMS > TimesTen) 22

23 Centralized vs Distributed 비교 Centralized Configuration Distributed Configuration Installation 동일시스템에 Oracle RDBMS 와 TimesTen 를설치함 WAS 서버에 TimesTen 를설치함 Auto Refresh 오라클 RDBMS 에변경된데이터 (Commited Data) 를가장빠른속도로 TimesTen 에반영됨. 오라클 RDBMS 에변경된데이터 (Commited Data) 가매우빠른속도로 WAS 에설치된모든 TimesTen 에반영됨 Performance Availability 만약 3 개 Node 의 WAS 에서활성트랜잭션이증가한다면 DBMS 시스템의자원경합에의한속도저하가간헐적으로발생할수있음. TimesTen 장애발생시 TimesTen 도입전과동일한형태의처리가보장되나어플리케이션의성능을기대할수없음. 활성트랜잭션이증가하여도 WAS 안에존재하는개별 TimesTen 에서처리하므로안정적인어플리케이션속도를보장함 3 개의 WAS 에서운용되는 TimesTen 중일부가장애가발생하더라도나머지정상운영되는 TimesTen 에의해어플리케이션의성능을유지할수있음. 23

24 Oracle TimesTen 사용장점
