11g从活动数据库复制数据库

原创 Oracle 作者:安佰胜 时间:2014-03-19 17:06:19 0 删除 编辑


11g新特性,duplicate database,文件不落地,直接从库复制库

db1:
189.168.0.11

db2
189.168.0.22


LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = db1)(PORT = 1521))
    )
  )
 
ADR_BASE_LISTENER = /opt/oracle
 
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = zaradb)
      (ORACLE_HOME = /opt/oracle/product/11.2.0/db_1)
      (SID_NAME = zaradb)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = db2)(PORT = 1521))
    )
  )
 
ADR_BASE_LISTENER = /opt/oracle
 
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = zaradb)
      (ORACLE_HOME = /opt/oracle/product/11.2.0/db_1)
      (SID_NAME = zaradb)
    )
  )

db1=
(DESCRIPTION=
  (ADDRESS=(PROTOCOL=tcp)(HOST=189.168.0.11)(PORT=1521))
  (CONNECT_DATA=
     (SERVICE_NAME=zaradb)
  )
)


db2=
(DESCRIPTION=
  (ADDRESS=(PROTOCOL=tcp)(HOST=189.168.0.22)(PORT=1521))
  (CONNECT_DATA=
     (SERVICE_NAME=zaradb)
  )
)


listener动态注册,口令文件一致
orapwd file=?/dbs/orapworcl password=oracle

db1归档open
db2启动到nomount

rman target sys/oracle@db1 auxiliary sys/oracle@db2

 

duplicate target database to ZARADB from active database nofilenamecheck;


注意事项
监听必须是静态注册
