在相同的主机上创建一个duplicate数据库

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.

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：

RMAN> duplicate target database to dupdb;
