Oracle on AWS RDS Migration - 성기명

Oops !~~~~~
 Oracle Database 9iR2(9.2.0.8) + Data Size 300GB
 HP-UX 11.11 Model 9000/800/N4000-55
 CPU : PA8600(PA-RISC 2.0) 550MHz * 4EA
 RAN : 6144MB(6GB)
 OS/HW/DB 모두 End Of Support(EOS)

Oracle on AWS RDS로 이관 시 고려 사항
 Oracle Database License 관련 내용 확인
 License Included와 Bring Your Own License(BYOL) 지원
 License Included: Oracle DB SE One, SE Two
 BYOL : 모든 Oracle DB 제품 지원
 지원 가능한 Oracle DB Version?
 Oracle Database 12cR1(12.1.0.2)
 Oracle Database 11gR2(11.2.0.4)
 지원 가능한 이관 방법은?
 Exp/Imp, Data pump등 다양한 이관 방법 지원
 이관 Data Size 및 임시파일(Dump File) 보관 공간 확보 여부?
 Storage를 이용한 Data Dump File을 보관 가능
 최대 Downtime 가능 시간은?
 무 정지 이관 시 AWS DMS 및 3rd Party Tool 사용 가능
 Data 성격 및 국내 IDC 존재 여부?
 개인정보의 경우 국외 이전의 거의 불가능 함.

Oracle on AWS RDS로 지원하는 이관 방법
 Oracle SQL Developer
 Oracle에서 제공하는 Java Base SQL Tool를 이용
 작은 Size의 Data Migration에 적합
 추가 기능을 설치하면 Mysql 및 기타 DBMS도 지원 함
 Oracle Data Pump
 가장 일반적인 Migration Tool 이며, 빠른 이관 속도를 보임
 DBMS_FILE_TRANSFER Option을 사용 해야 함
 Oracle Export/Import
 전통적인 Migration Tool이며, Oracle 8i 부터 지원 함
 LOB Data Type이 있을 경우 매우 느림
 Oracle SQL*Loader
 구분자로 구분된 Text File을 Table에 Insert 하는 방식
 Oracle Materialized Views
 Database link를 이용하여 Materialized Views를 이용하여 이관
 CDC Tool를 이용한 이관 방법

ance-store-swap-volumes.html
• OUI의 “-ignoreSysPrereqs “ 옵션 사용하여 SWAP 없이 설치 가능
 t2.micro는 “X Window System”를 제공 하지 않음
• Yum을 설정하여 “X Window System”은 가능 함.
• OUI의 “-silent “ 옵션 사용하여 X Windows System 없이 설치 가능
