rman duplicate

11g 에서는 rman 을 이용하여 DB가 백업본이 없어도 운영중인 상태에서 복제가 가능하다.(FROM ACTIVE DATABASE 이용)

현재 서버 ORCL DB -> 다른서버의 ORCL2 라는 이름으로 복제해 보자. 귀찮아서 새로운 서버의 화일 경로는 바꾸지 않았다.

1. source 와 target에서 각각의 서비스를 tnsnames.ora 에 모두 반영

target 관련 TNS에는 from active database 옵션을 써서 복제할 경우 startup nomount 상태시 target 의 listener 가 blocking 되어 통신이 되지 않으므로 (UR=A) 항목을 추가해 줘서 에러를 방지해 준다.

TEST2 =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = single2)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = TEST2) (UR=A)
    )
)

2. 양쪽 listener start

3. source 에서 pfile 을 생성하여 target 환경에 맞게 수정후 init 화일 생성

SQL> create pfile from spfile;

생성된 pfile 을 이용하여 target 에 init화일을 생성해준다.

환경에 맞게 db_name 등을 수정반영

root.sh or rootupgrade.sh 수행후 OUI 죽었을때 후속조치

11g RAC 설치중 해당 과정 화면에서 root.sh 까지는 멋지게 성공하였으나 Session 오류나 기타 문제로 OUI 화면이

없어져 버렸을 경우 아래와 같이 조치하면 후속작업(Configure Oracle Grid Infrastructure for a Cluster 이하)을

계속 진행하고 마무리 지을수 있다.

$GRID_HOME/cfgtoollogs/configToolAllCommands

즉 text 모드로 진행하여 설치완료 할 수 있다.

scan ip 변경

SCAN IP를 105 -> 205 로 바꾸어 보자.

1. [root:/root]#crsctl stop crs

2. vi /etc/hosts

# SCAN
#192.168.56.105 rac-scan

192.168.56.205 rac-scan

3. [root:/root]#crsctl start crs

4. 확인해 보면 아직 반영 안 되어 있다.

[root:/root]#srvctl config scan
SCAN name: rac-scan, Network: 1/192.168.56.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /rac-scan/192.168.56.105

5. modify 해준다.

root 유저로 실행

[root:/root]#srvctl modify scan -n rac-scan

6. 확인 끝
