1. hosts 파일 편집

모든 서버의 /etc/hosts 파일에 IP와 호스트명 정보 입력
[primary IP] [primary 호스트명]
[standby IP] [standby 호스트명]
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

10.0.1.71   seoul
10.0.5.71   seoul_dg
10.0.1.72   busan
10.0.5.72   busan_dg


실제 운영 환경에서는 업무에 부담을 줄이기 위해 별도의 DG 전용 망을 사용하는 것을 권장합니다.

2. Primary  네트워크 설정

A) listener.ora 파일 작성

primary 노드 listener.ora 파일에 data guard에서 사용할 리스너 정보 추가

      (SID_NAME = orcl)
    )
  )


Primary 노드에 Static 리스너 설정을 추가합니다.

B) tnsnames.ora 파일 작성

primary 노드 tnsnames.ora 파일에 data guard에서 사용할 접속 정보 추가

    )
    (CONNECT_DATA =

      (SERVICE_NAME = orcl)
    )
  )

BUSAN_SYN =
  (DESCRIPTION =

    이러한 경우, 아래와 같이 DG Broker에서 아래와 같이 StaticConnectIdentifier 변경 작업을 추가로 진행해야 할 수 있습니다.

    예: seoul => seoul_dg / busan => busan_dg 로 변경

    DGMGRL> show database orcl_stby StaticConnectIdentifier
      StaticConnectIdentifier = '(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=busan)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=orcl_stby_DGMGRL)(INSTANCE_NAME=orcl)(SERVER=DEDICATED)))'
    
    DGMGRL> edit database orcl_stby set property StaticConnectIdentifier = '(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=busan_dg)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=orcl_stby_DGMGRL)(INSTANCE_NAME=orcl)(SERVER=DEDICATED)))';
    Property "staticconnectidentifier" updated
    
    DGMGRL> show database orcl_stby StaticConnectIdentifier
      StaticConnectIdentifier = '(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=busan_dg)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=orcl_stby_DGMGRL)(INSTANCE_NAME=orcl)(SERVER=DEDICATED)))'
