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

4. target 에서 원격접속을 위해 passwd 화일 생성
[oracle:/oracle/product/11.2.0.4/dbs]#orapwd file=orapwORCL2 password=manager entries=10
5. nomount 로 DB기동
export ORACLE_SID=ORCL2
sqlplus "/as sysdba"
SQL> startup nomount
6. rman 접속
target 에서
[oracle:/home/oracle]#rman target sys/manager@ORCL auxiliary sys/manager@ORCL2
