在相同的主机上创建一个duplicate数据库
source db:dbtest
auxiliary db:dupdb
duplicate database会自动分配一个新的DBID
要确保auxiliary channel能访问到所需的备份以及归档日志
1.备份source db
$ rman target / RMAN> backup database format ='/home/oracle/arch/dbbak_%U' plus archivelog;
2.修改监听文件,静态注册监听
SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (GLOBAL_DBNAME = testdb) (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1/) (SID_NAME =testdb) ) (SID_DESC = (GLOBAL_DBNAME = dupdb) (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1/) (SID_NAME =dupdb) ) )
3.修改tnsnames.ora文件
DBTEST = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = testdb)(PORT = 1521)) ) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = dbtest) ) ) DUPDB = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = testdb)(PORT = 1521)) ) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = dupdb) ) )
4.为duplicate 数据库创建参数文件initdupdb.ora
db_name=dupdb db_block_size=8192 compatible=11.2.0.4.0 remote_login_passwordfile=exclusive control_files=('/u01/app/oracle/oradata/dupdb/control01.ctl','/u01/app/oracle/oradata/dupdb/control02.ctl') db_file_name_convert=('/u01/app/oracle/oradata/dbtest','/u01/app/oracle/oradata/dupdb') log_file_name_covert=('/u01/app/oracle/oradata/dbtest','/u01/app/oracle/oradata/dupdb')
#其他参数是可选的
5.启动auxiliary database(duplicate database)
$ export ORACLE_SID=dupdb $ sqlplus /nolog SQL> connect /as sysdba SQL> startup nomount pfile='/u01/app/oracle/product/11.2.0/dbhome_1/dbs/initdupdb.ora' ORACLE instance started. Total System Global Area 317370368 bytes Fixed Size 2252784 bytes Variable Size 260046864 bytes Database Buffers 50331648 bytes Redo Buffers 4739072 bytes SQL>
6.启动rman
$ export ORACLE_SID=dupdb $ rman Recovery Manager: Release 11.2.0.4.0 - Production on Thu Jun 25 07:52:09 2015 Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved. RMAN> connect target sys/system1@dbtest connected to target database: DBTEST (DBID=1275290034) RMAN> connect auxiliary / connected to auxiliary database: DUPDB (not mounted) RMAN>
7.启动duplicate database操作
RMAN> duplicate target database to dupdb;
以下为duplicate命令的执行结果:
